Lacetti 2003 Review

GM Daewoo Raises the Bar for the Mid-Size Car Introducing the All-New Lacetti
28 August, 2003

GM Daewoo is launching its second model on to the Australian market, the all-new Lacetti. This four-door mid-size sedan is the first model in a new line, which will also include a hatchback available late 2004 and a station wagon currently under development.

"The new Lacetti sets a benchmark in value by providing plenty of car for the money. We believe it's raised the bar for the mid-sized car and is another example of GM Daewoo driving value for Australian buyers," said Mr Graeme Coverdale, Managing Director, GM Daewoo Australia.

The name "Lacetti" is derived from the Latin word "Lacertus" which means energetic, muscular, youthful and full of strength.

Its elegant, sporty design by the world-renowned Italian design studio Pininfarina, the comfort and safety features, new engine and value for money make it an attractive proposition for Australian families looking for a mid size car.

The new Lacetti features a new Australian-built Family II 1.8L DOHC engine, which generates 90kW/122hp at 5800rpm and fuel consumption of 8 litres per 100 km manual transmission and 9.3 litres per 100km automatic transmission (Source: Department of Transport & Regional Services in simulated driving conditions on a rolling road July 2003).

GM Daewoo's philosophy of 'driving value' by providing plenty of car for the money has been underscored in the new Lacetti, not only by the generous number of standard features, but also by the dimensions of this modern front wheel drive car. One example is its exterior length. At 4.5m it can be considered long for this class of mid size car.

Dual driver and front passenger airbags are provided as standard equipment and high tensile steel sheets are used in 40% of the vehicles composition for cabin rigidity and strength. There are five three-point seatbelts and three Isofix fittings to attach a child seat. With the three-layer structure, the sturdy bumpers can withstand minor collisions up to 5 km/h. Ventilated front disc brakes and rear disc brakes are standard on the new Lacetti.

"The standard comfort and convenience features of the Lacetti include air conditioning with pollen filter, front and rear power windows, power mirrors, power steering, remote central locking and keyless entry with alarm and immobilizer featuring a 30 second reset function, a remote release for the boot in the key, height-adjustable driver seat, drivers seat lumbar support and height-adjustable seatbelts for the driver and front passenger, tilt adjustable steering wheel plus a six speaker stereo system with radio and in-dash single CD player," he said.

The back seats can be folded down in a ratio of 60:40, and there are storage trays and holders like a cup/can holder in the front center console, a pocket on the side of the front passenger's seat, compartments in all four doors, a ticket clip in the driver's sun visor, sunglasses holder on the drivers side and an under seat storage tray on the passenger side. A12volt power outlet is located in the front centre console and a glove box for the owner's manual or personal items.

The Lacetti will be available in a range of 10 colours - galaxy white (solid), imperial blue (mica), denim blue (mica), modern green (mica), Khaki green (mica), red rock (solid), mélange beige (metallic), mint green (metallic), pearl black (mica) and poly silver (metallic)

The Lacetti four-door sedan will go on sale nationally on September 1 with a RRP of $19,490 with a manual transmission. This price excludes dealer delivery and government charges. The optional automatic transmission is available for an additional RRP of $2,000 and optional metallic/mica paint is an additional RRP of $195.

"We are keeping our feet on the ground, because this is where our competitive edge is - offering customers great products at reasonable prices and providing our dealers with a sustainable long term business," Mr Coverdale said.

The Lacetti will be available at over 120 GM Daewoo showrooms throughout Australia.

GM Daewoo, a member of the General Motors group, is the exclusive distributor of the Lacetti in Australia.

International Development on Four Continents

The development of the Lacetti began in November 1999 and went into production after a development period of 30 months, which was internationally oriented from the very beginning. The Lacetti prototypes covered nearly two million test kilometres on four continents. Kapuskasing in Canada and Arjeplog in Sweden were chosen for the punishing winter testing, after which the test vehicles were subjected to the merciless heat of Alice Springs in Australia and Idiada in Spain. 111 prototypes in a total of 194 crash tests were carried out in the United States and at GM Daewoo's development centre in Bupyung, South Korea, according to Euro NCAP standards. During the final endurance training, the test cars did endless laps of the test circuit near Beijing, China, and the MIRA circuit in Millbrook, UK.

The list of key development partners for the project includes SiemensAutomotive (airbag systems, emissions control), Bosch (ABS), Aisin and ZF (automatic transmission), Pininfarina (design) and Delphi (engine management system).


The new Lacetti is produced at the Gunsan plant on the western coast of South Korea. The industrial complex covers an area of 2.4 million square meters and includes among other things a small proving ground for carrying out handling trials and running in exercises. With the introduction of the new compact class generation, the level of automation at the plant (which also produces the Tacuma compact multi-purpose vehicle) is being further increased. It has now reached 85 percent in the press shop and 98.4 percent in the body shop. At the end of 2002, GM Daewoo's workforce at this modern production plant was 1,884.


Lacetti Body Language: The Power of Proportion

  • Body design by Pininfarina
  • Powerful lines
  • Elegant, Modern Interior
  • Suprisingly Spacious Cabin

The new Lacetti is the second new Daewoo model after the Tacuma to originate at the internationally renowned Pininfarina design studio near Turin, Italy, the home of legendary Ferrari designer. The cooperation with world-famous Italian car designers is thus becoming a trademark for the model range of the Korean manufacturer. The designs of the Kalos, the small five-door hatch successfully introduced in April, and the lovable Matiz, also came from Turin, from Giorgetto Giugaro's ItalDesign studios.

The look of the new Lacetti is characterized by strong, clearly defined contours. Lorenzo Ramaciotti, Pininfarina's Managing Director, explains: "We have always put our trust in simplicity and the power of proportion, and we have continued this philosophy with GM Daewoo's new compact sedan."

The body language of the new Lacetti is modern and dynamic. From the side, it is dominated by its wedge shape and clearly accentuated shoulders. The roofline drops down to the high rear section almost like that of a coupé, and the prominent wheel arches give the front-wheel drive vehicle a solid stance.

The face of the Lacetti clearly distinguishes it as a member of the current GM Daewoo family. The crease lines on the hood converge towards the front of the car and continue all the way down to the front apron. The three-section chrome grille - a traditional Daewoo design cue - is integrated harmoniously into the hood and crowned by the company's modern new logo. The sleek, cylinder shaped, jewel-effect headlamps and their clear-glass covers the three cylindrical lamps in each unit.

The Lacetti's unique greenhouse design gave birth to the six-window (additional quarter glasses) with a greenhouse length of 2780mm. Greenhouse length refers to the distance between the base of the front windshield to the base of the rear windscreen.

The high defined wheel arches have a European feel finished by the body coloured outside mirrors, chrome-pressed door handles and body-side moulding with body coloured front and rear bumpers.

The rear of this mid-size sedan has been designed so that the airflow encounters a minimum of resistance. The boot lid is positioned comparatively high, making it easy to continue the aerodynamic, coupé-style roofline to the end of the body. This also has a positive effect on the size of the trunk. Pininfarina has been particularly successful at harmonizing the rear and side lines. "We focused a great deal of attention on the form of the rear lights," says Ramaciotti. "The clean-cut design lines of the body lead to and define the three dimensions of the lights, giving them a characteristic diamond shape and creating the impression of solidity and quality."

Interior: New, Modern and Roomy

The interior is a modern horizontal style with a new colour scheme which surrounds the cockpit on three sides, dividing the interior into an upper dark-gray and lower light-gray section. Modern grey plush seats finish the look.

All the key information for the driver is accommodated in three circular instruments that have been designed with silvering detail for greater visibility and jade green illumination and translucent cover when driving at night.

The radio and single in-dash CD stereo system and the buttons for the air-conditioner are easy to reach for the driver and passenger in the center console. The matte silver finish on the steering wheel spokes, and on the step gate automatic transmission shift lever console, adds a sporty touch to the interior.

The interior is surprisingly spacious with high hip point seating giving occupants easier entry and exit and good all round visibility.

Here are the interior dimensions:

Cabin height

* Greenhouse length refers to the distance from the base of the front windshield to the base of the rear windshield.

** Couple distance refers to the distance between front and rear passenger hip points.

The Lacetti cabin is a driver-orientated environment where the driving position may be changed to suit drivers of various stature. The driver's seat may be adjusted for height and provides adjustable lumbar support. The steering wheel and drivers seatbelt may be tilted for height. The headrest tilts as well as being height adjustable.

Interview with Lorenzo Ramaciotti, General Manager of Pininfarina Design

"Elegant Lacetti with Tight Character Lines and a Dynamic Stance"

All new Lacetti was the second Pininfarina project after the Tacuma.

Barcelona. Cooperation with famous Italian designers has become a Daewoo trademark: While Matiz and Kalos received their own independent shape and form from Italdesign and designer, Giorgietto Giugiaro, the new Lacetti is the product of cooperative efforts between the GM Daewoo design center and the specialists at Pininfarina in Turin under the guidance of General Manager Lorenzo Ramaciotti. The mid-size sedan is characte-rized by strong, clean-cut contours. Typical for the newcomer's styling are the bold lines on the engine hood, which guide the eye to the new company badge and the chrome-plated radiator grille. The sturdy bumpers can withstand collisions at speeds of up to 5 km/h without damage.

The interior is elegant and modern. Three clearly laid out, circular displays provide all the information the driver needs. The cockpit splits horizontally, contrasting the dark gray upper area against a light gray lower section. The center console gives the interior a sporty look. It houses the radio CD Stereo system format as well as the temperature controls for the standard air conditioning.

In an interview conducted recently on the premises of Pininfarina Ricerca e Sviluppo S.p.A. in Cambiano near Turin, Italy, the company's CEO and General Manager Lorenzo Ramaciotti described the development process of the Lacetti.

Interview with Lorenzo Ramaciotti, CEO and General Manager of Pininfarina Design

Question: How and when did Pininfarina first come into contact with Daewoo?

Ramaciotti: In 1996 we were asked to participate in the Tacuma project. Our proposal for the exterior design developed was eventually chosen for production.

Question: This successful cooperation led to another project, today known as Lacetti?

Ramaciotti: Yes, in May 1999 Daewoo contacted us with a comprehensive briefing for the new Lacetti. First renderings were presented at the beginning of July and a 1:1 model was shipped to Seoul/Korea in October. Part of our assignment, by the way, was to achieve an aerodynamic drag coefficient of 0,30.

Question: How did the project progress?

Ramaciotti: The cooperation was excellent, GM Daewoo is a very professional partner and it has been a pleasure to work with them.

Question: Let's talk about the car itself. How would you characterize its main features?

Ramaciotti: Pininfarina has always believed in simplicity and the power of proportion. So what we tried to achieve with the Lacetti was a very simple and clear shape but with a dynamic and modern treatment. Thanks to the pronounced wedge-shape and sharp shoulder line, the car looks athletic and streamlined. Another element that gives the car its dynamic stance is the very prominent treatment of the wheel arches.

Question: To go into a bit more detail, what can you tell us about the Lacetti front?

Ramaciotti: The front of the car is like the face of a person. So we tried to embody as much personality as we could in the front of this car. The three apertures of the grill incorporate the traditional Daewoo design, but in a much more modern and integrated shape. There's a flowing, continuous movement along the raised center of the hood through the bumper and down to the bottom of the car. As the headlights are the eyes of the car, we made them large and very bright. They also have a very interesting interior treatment.

Question: What most people see on the road is the back of a car. Could we have your comments here as well?

Ramaciotti: On the one hand, the trunk lid is the continuation of the roofline, creating a single aerodynamic surface right to the end of the car; on the other hand, to allow for a large luggage compartment, it has to be quite high. We harmonized the characteristic line of the side with the lines of the rear. Special attention has also been given to the shape of the rear lamps. Like a diamond, its three-dimensional shape reaches nicely into the three surfaces of the car creating an impression of solidity and quality.

Question: Are those the attributes you applied to the interior as well?

Ramaciotti: Indeed. In the interior you find the same styling cues that we used for the exterior: Simplicity, solidity and practicality. The instruments, for instance, are very easy to read and have a metal surround that adds a sporty note to the interior. Many people will be surprised by the generous amount of interior space in a car that from the outside looks more like a sports sedan or even a coupé.

Question: Last question: Are there any typical Italian elements in the design of Lacetti?

Ramaciotti: Yes, of course. The essence of its design and its elegant proportions are very much Italian. Italian cars are all about elegant proportions and nice surfaces with a few tight lines, exactly like the new Lacetti.

Lorenzo Ramaciotti, CEO and General Manager of Pininfarina

Lorenzo Ramaciotti was born in Modena/Italy in 1948. He graduated in Mechanical Engineering in 1972 at the Politechnic University of Turin. He joined Pininfarina as a designer in 1973, working in the styling department, later being responsible for models and prototypes construction. In 1982, when Pininfarina Studi e Ricerche moved to its present premises at Cambiano, Lorenzo Ramaciotti assumed the position of Deputy General Manager.

In 1988 he was promoted to his present position of General Manager. Since January 1, 2002 he has also held the position of CEO of the company, the name of which the Board of Directors changed on December 20 2001 from Pininfarina Studi e Ricerche S.p.A. to Pininfarina Ricerca e Sviluppo S.p.A.

Body, Stability, Safety

Generous Dimensions, Stable Body and Safety Measures

  • Long wheelbase and generous dimensions
  • 40 percent high-strength steel
  • Comprehensive safety measures

The brief given to the engineers designing the all-new Lacetti included the following: provide a generous amount of space but keep it as compact as possible, ensure maximum protection of the passengers but keep the weight to a minimum, and maintain high manufacturing precision in production. As if that was not enough, they also had to make sure that a hatchback and station wagon variant could be built on the same platform at a later stage.

After much deliberation, the designers finally decided to adopt a wheelbase of 2,600 mm. With its overall length of 4,500 mm, the Lacetti looks streamlined and athletic. By positioning the engine compartment and trunk as far to the front and back as possible, the engineers created a maximum of space inside. Thanks to clever packaging, the front and rear overhangs nevertheless remain reasonable at 885 and 1,015 mm respectively.

The impressive stature of the new Lacetti is further illustrated by its other vital statistics: The tread width of 1,480 mm lifts the new model into the upper third of its class, as indeed does the overall width of 1,725 mm. Its relatively low height of 1,445 mm, on the other hand, underlines the dynamism of the new compact-class vehicle, a characteristic that is also expressed in its sporty design.

The Lacetti has a frontal area of 2.155 m². The drag coefficient of 0.338 results in wind resistance equivalent to 0.71 m². The surprising thing is that, despite the Lacetti's many standard features, GM Daewoo has succeeded in keeping the kerb weight down to 1,235 kg (1.8 with automatic transmission).

Here are the vital statistics of the new Lacetti at a glance:

Length x width x height (mm) 4,500 x 1,725 x 1,445
Wheelbase (mm) 2,600
Tread front/rear (mm) 1,480/1,480
Drag coefficient 0.338
Minimum Ground Clearance 160
Drag resistance (m2) 0.71
Kerb weight (kg) Manual 1,210
Automatic 1,235
Steel Tank capacity (liters) 60

The reason for the car's comparatively low weight despite its high torsional rigidity and comprehensive crash stability is the large percentage of high-strength and extra high-strength steel in the Lacetti. It accounts for 40 percent of the body shell and plays a key role in the high stability of the passenger compartment.

Protection: Passenger Compartment Made of High-Strength Steel

The cabin has high torsional rigidity and crash stability due to the high-strength and extra high-strength steel in the body shell. High-strength steel has also been used, for example, for the straight front frame side rails with their hexagonal cross section. They split up to create load paths that can absorb impact energy both in a cross-member positioned below the bulkhead and in members located in the doorsills. These members, as well as the connections to the A and B pillars of the body, the pillars themselves, the center tunnel and the cross structures at the front and rear, are also made of high-strength steel.

The car interior's new hexagonal structure is designed for absorption of impact shock. The energy-absorbing sandwich construction of the bulkhead and dashboard, and impact-absorbing rigid foam elements in the front doors affect the direction of shock energy so it is deflected away from passengers at impact.

The B pillar is three pieces welded using a piece tailor welded blanking method, a wide C pillar and side door impact beams for reinforcement and impact distribution designed to minimize impact of force on the cabin.

The progressive crumple zones with frontal three way impact diffusion system to absorb impact through pre-determined body deformation with the use of high strength steel in the cabin, hexagonal front longitudinal frame, strong dash panel, knee bolsters, dual driver (60litres) and front passenger (120 litres) airbags, five three point seatbelts and three ISOFIX child seat tether anchorage points are designed to minimize the force of impact on the passenger cabin.

Interior, Equipment

Space, Comfort and Security

  • Generous rear-seat space
  • Lots of standard equipment and storage functionalities
  • Surprising level of convenience, comfort and security

GM Daewoo's philosophy of providing 'plenty of car for your money' has been underscored in the new Lacetti not only by the generous number of standard features, but also by the amount of space available in this modern front-wheel drive car.

One good example is its exterior length. At 4,500 mm and with the rear space, it's surprisingly spacious.

Here are the most important interior dimensions at a glance:

Length/width/height (mm) 1,925/1,460/1,180
Head room front/rear (mm) 993/961
Legroom front/rear (mm) 1,068/932
Shoulder room front/rear (mm) 1,389/1,363
Hip room front/rear (mm) 1,338/1,368
Boot volume (liters) 404

Storage Spaces

The back seats can be folded down in a ratio of 60:40 for flexible storage and under seat trays and cup holders in the front center console, a pocket on the side of the front passenger seat, seatback pockets on the drivers and front passengers seat, storage compartments in all four doors, mobile phone holder in the back door storage compartments, rear seat centre armrest with dual cup holder, glove box, sunglass holder on the drivers side, shopping bag hook on the front passenger seat and in the boot and a ticket clip in the driver's sun visor.

Convenience and Comfort

The standard equipment includes air conditioning with pollen filter, front and rear power windows, power mirrors and power steering.

Access to the vehicle is by the remote central locking and keyless entry system located in the Lacetti ignition key. There is an anti-theft alarm and immobilizer with reset function.

The vehicle doors can be locked and unlocked by a high frequency transmitter in the key, which can sense an intrusion into the vehicle through the cabin doors, boot or the engine hood. Once activated it produces a warning signal (siren). When the vehicle is unlocked with the remote control, the hazard lights flash twice, which may help locate the vehicle when parked close by.

If the doors, engine hood or boot are unlocked using remote keyless entry and are not opened within 30 seconds, all the doors are automatically re-locked and the system re-armed (remote central locking, alarm and immobilizer). The hazard lamps blink and siren chirps once to indicate the system has been rearmed. The security indicator is located on the driver's door snippet lock button surround and will flash when armed. The remote release for the boot is also featured on the ignition key for more convenient access.

The Lacetti has a six speaker stereo system with radio and in-dash single CD player as standard equipment. In the centre console is a 12V power outlet for an electrical accessory. And for the driver and front passenger there is a vanity mirror under each front sunvisor.

Suspension, Steering, Brakes, Quiet Drive

Suspension System for a Comfortable Drive

  • Sophisticated independent rear suspension
  • Four wheel disc brakes
  • Noise suppression measures for a quieter drive

The design and development work on the chassis for the new Lacetti actually began with a blank sheet of paper. "Our aim," explains GM Daewoo's Chief Engineer, Dr. Ki-Joon Yu, "was to measure ourselves against the very best in our market segment in terms of ride comfort and particularly in the prevention of noise and vibration. This is why we decided to go for independent suspension for the rear axle."

The new Lacetti features McPherson struts with gas-pressure shock absorbers on all four wheels. A suspension arm at the front and two additional wishbones and a trailing arm at the rear ensure precise wheel control. A front stabilizer bar installed directly across the strut enhances maneuverability. A H-type highly rigid, front cross member, rear wheel bearings and pigtail spring applications add to the driving performance.

Well dimensioned cross members also make a significant contribution to enhancing comfort. Push-pull struts control the standard torsion-bar stabilizers on both axles.

The Lacetti comes standard with 15-inch wheels and 195/55R15 tyres and has four- wheel disc brakes with 7 + 8 inch Tandem Boosters for heat protection and braking force. The internally ventilated front brakes have a diameter of 256 millimeters at the front and 258 millimeters at the rear.


The standard power-assisted steering on the Lacetti features a stronger torsion bar and a pump with a higher flow rate. It has been tuned to give more feedback to the driver, "We call it 'confidence steering'," says H.G. Chae, Head of GM Daewoo's Test and Development Group in Seoul. "The driver feels that the steering is true to center and offers rapid response with a continuous build-up of steering resistance." The steering wheel can be tilt adjusted for the height of the driver. The turning circle is 10.4 meters.

Quiet Ride

With numerous noise suppression systems, the Lacetti offers occupants a quieter ride. Connecting the alternator, power lamp and air conditioning compressor with one belt has reduced engine noise and improved durability as the belt is controlled by an auto-tensioner.

Using a hydraulic engine mounting with both engine and transmission has further reduced engine noise. The installed road-type torque reaction halts vibration from reaching the car body and controls quick vibration arising from engines surges.

Engine noise is trapped by an insulation-equipped engine cover, which wraps around the engine so the noise route is effectively blocked by the filter foam sealing process. The dome shaped cylinder block also minimizes engine noise and vibration and the aluminum engine oil pan absorbs vibrations. There is insulation on the dash panel, fender, front floor, B-pillar, rear floor and under the rear seat front area on the floor.

Using a 7.8-litre air cleaner and 8-litre resonater has reduced intake noise. Exhaust noise has been minimized by the triple muffler system, which has a centre muffler and large volume (22.8 litre) muffler. Wind noise has been reduced through an installed rain channel, which also prevents rain from flowing down the front side windows.

Powertrain, Transmission

New Engine for Sporty Performance

  • 1.8L DOHC Family II Engine
  • Built by Holden in Australi
  • Delphi Engine Management System
  • ZF Fuzzy Logic electronic automatic transmission

The new Lacetti will take to the road with a new, modern and fundamentally modified four-cylinder Family II engine operated by two overhead camshafts. Apart from improving efficiency the engine was designed to deliver smoother operation and minimize engine vibration. The engine is equipped with a five-speed gearbox as standard, while a new optional four-speed ZF Fuzzy Logic electronic automatic transmission is available for an additional RRP of $2000.

The new Lacetti 1.8L Engine

The new engine is a 1.8-litre DOHC Family II and is manufactured in Australia at Holden. Its displacement is 1,799 cm3, it generates a maximum of 90 kW/122 hp at 5,800 rpm, and has a maximum torque of 165 Nm at 4,000 rpm.

The new Lacetti is equipped with a Delphi Engine Management System (ECM). The ECM controls the entire engine management system with a Central Processing Unit operating at 32 bits compared with 8 bits in the previous engine.

It is characterised by efficient fuel consumption and low noise. A cylinder head and an induction valve device were added to the engine and a newly designed adjustable induction system was applied for optimum air intake. Six coolant pipes lower the average temperature of the engine's cylinder head bloc, leading to better engine performance, lower fuel consumption and increased durability.


Combining the 1.8-litre engine with the new optional electronically controlled four-speed automatic transmission makes for even greater smoothness. It is built by the acclaimed German company, ZF, and offers sportier drivers the possibility to change the gears themselves. The Adaptive Gear Control automatically adjusts to the driving conditions and the driver's particular style by the use of Fuzzy Logic.

Fuzzy Logic is a software type, which is programmed into the Transmission Control Module (TCM), which assesses driving conditions and decides when to select proper shifting mode for that particular condition in real time. Once the logic is selected, eg shifting mode, the TCM follows the predetermined shifting pattern. However, in case driving conditions change, the fuzzy logic assesses the condition again and changes the shifting modes accordingly.

Shift modes learned are:

  • Economy/Medium/Sporty
  • Load 1/Load 2/Load 3
  • Shifting Inhibit

Economy/Medium/Sporty/Load 1/Load 2/ Load 3 are shift pattern selections in the long term where as Shifting Inhibit is a dynamic correction in the short term.

The new Economy is tuned into achieving better fuel consumption when compared to conventional Economy mode. Sporty mode is the former Power mode and Medium is a tuning in between Economy and Sporty. These three shift modes are selected mainly for flat roads. The TCM selects economy mode for most of the driving cycle to achieve maximum fuel economy. Sporty mode is selected for a shorter time and when maximum power is required.

The transmission has an Electronic Lock-Up Torque Converter. A planetary gear train establishes the mechanical gear ratios. The electronic-hydraulic control makes controlled power shifts and various shift programs possible.

The special feature of this transmission is that it operates without free wheeling. Shifting between individual gears takes place by way of overlapping clutch engagement.

The advantages of overlapping shifting are that the transmission can be more compact in design and is lighter with a small number of shift elements. Higher efficiency results due to lower drag losses and there is lower peak torque acting on the components and drive line.

The corrugated automatic transmission shift gate prevents accidental selection of neutral when shifting from low ratio to Drive while the Hold feature allows the car to move off from standstill in second or third gear on slippery roads. The Brake shift interlock does not allow shifting of the gear lever from Park to Reverse or Drive without the foot brake engaged.

The standard manual transmission has a hydraulic concentric slave cylinder (CSC), which replaces the conventional clutch linkages. In place of the fork and thrust bearing, the hydraulic CSC slides out and pushes against the clutch spring and the CSC piston automatically returns when the clutch pedal is depressed. This means there is less clutch pedal effort required as the mileage of the car increases. In normal driving conditions, there is improving clutch efficiency, durability and engagement feel, that is, it reduces the "softening feel of the clutch over time".

The synchromesh on reverse gear in the manual transmission minimizes grating noise when reverse is engaged.

The designers have reduced noise and vibration by lowering the cylinder block skirts and fitting an aluminum oil sump. Other factors contributing to noise suppression are the insulation of the engine hood and the use of larger-than-normal air filter housings and exhaust systems.

Finely tuned hydro mounts are used both for the engine and for the transmission unit. The third suspension point is a torque support, which effectively restricts the movement of the engine and is also insulated from the body to prevent vibrations.
