Mitsubishi Lancer Evolution X


The development goal for the Mitsubishi Lancer Evolution X was to make the car as fast as possible, while also making it as safe to drive as possible. To that end Mitsubishi Lancer Evolution X is loaded with the very latest in automotive engineering technology, including the S-AWC (Super All Wheel Control) vehicle dynamics control system and the newly developed, power-efficient Twin Clutch SST (Sport Shift Transmission). Mitsubishi Lancer Evolution X is a new-generation high-performance 4WD sedan that allows a new category of driver access to Mitsubishi's dynamic driving experience by underpinning speed with control, security and safety.
Mitsubishi Lancer Evolution X's handsome and aggressive functional design presents an intimidating and exciting aerodynamic exterior suggestive of its superior road performance. This is complemented by a functional interior that encourages the driver to concentrate fully on piloting his machine. Mitsubishi Lancer Evolution X uses the front end design identity common to all new Mitsubishi Motors sedans (inverted-slant nose with a trapezoidal grille design) first seen on the new Galant Fortis (Mitsubishi Lancer / Lancer EX in overseas markets). As well as shouting loud the aggressive qualities that mark a high performance sports sedan, the front fascia is crafted for optimum aerodynamic performance.
Mitsubishi Lancer Evolution X realizes very high levels of motive and driving performance thanks to its new high-output and lightweight 2.0-liter DOHC MIVEC turbocharged engine with aluminum block, an all-new body and stiffer suspension. Despite its turbocharged pedigree the new model earns a 3-star rating for emissions that are 50% lower than the requirements of the Japanese 2005 standards. And complementing its powerful and clean road performance is the kind of a safety specification one would expect of a new-generation high-performance model: SRS dual-stage airbags for driver and front passenger, SRS knee airbag for driver and adaptive front lighting system (AFS) are all standard equipment on the GSR trim level.
The Twin Clutch SST is a 6-speed automated manual transmission incorporating a dual automated clutch system to deliver lightning-fast, slick shifting for feel-good acceleration; while it also provides high-efficiency power transmission for outstanding fuel economy. In keeping with the higher output and torque developed by the new engine, Mitsubishi Lancer Evolution X is offered with a new 5-speed manual transmission that delivers smoother shifting and improved shift feel for those who prefer the joys and more direct control of manual shifting.
All Mitsubishi Lancer Evolution X GSR models are fitted with the S-AWC vehicle dynamics control system. The system intelligently manages several component systems to regulate drive torque and braking force at each wheel, reading and reflecting driver intent in real time over a wide range of situations. This allows drivers of all abilities to enjoy sporty driving with peace of mind.
Engine
Mitsubishi Lancer Evolution X is powered by a new turbocharged engine that adds a high-performance turbocharger to the 4B11-type 2.0-liter 4-cylinder 16-valve DOHC MIVEC unit used in the Galant Fortis. Developing more power over the full rev range, this engine generates more torque at 422 Nm (43.0 kg-m)/3500 rpm and has better response than its 4G63 predecessor. The new engine is also lighter and returns better environmental performance.
The application of continuously variable valve timing technology (MIVEC) to both intake and exhaust camshafts realizes valve timing optimally matched to engine speed and load to stabilize combustion characteristics and allow the engine to develop more power over the full rev range. It also improves emissions performance. Mitsubishi Lancer Evolution X earns a 3-star rating for emissions that are 50% under the Japanese 2005 Emissions Standards levels.
The new engine, excluding auxiliary equipment, is 12 kg lighter than the 4G63 thanks to the use of a die-cast aluminum cylinder block, head cover and chain case.
Using a titanium-aluminum alloy turbine wheel and aluminum alloy compressor wheel, the turbocharger features a shape-optimized compressor wheel that improves boost response and increases low-end and mid-range torque.
The adoption of a rearward facing exhaust manifold layout has, as well as improving exhaust efficiency, allowed the engine to be mounted lower, lowering the center of gravity. Other innovations have reduced intake/exhaust system losses and valvetrain friction, contributing to improved engine performance.
Transmissions
The GSR is available with the new Twin Clutch SST 6-speed automated manual transmission that eliminates the need for a clutch pedal and provides slick, smooth shifting. Twin Clutch SST puts odd (1st, 3rd, 5th) and even (2nd, 4th and 6th) gears on separate input shafts each with its own clutch and, through tight cooperative control with the engine, switches between these clutches to realize seamless and lightning-fast shifting for feel-good acceleration. Because it uses clutches rather than a torque converter to transmit power, Twin Clutch SST allows superior power transmission efficiency with little loss of motive power and returns excellent fuel economy. Twin Clutch SST allows the driver to choose between Autoshift fully automatic shifting and Manual Shift, where the driver can change gears as with a manual transmission. A toggle switch located at the base of the shift selector allows the driver to choose between Normal, Sport and Super Sport modes for the optimum shift scheduling for a wide variety of situations ranging from driving around town to tracing a tight line on a winding road.
Twin Clutch SST models are fitted as standard with steering column-mounted lightweight magnesium paddle shifters that allow the driver to shift manually without taking his hand off the steering wheel.
For drivers who enjoy having more direct control over their machine, the GSR is available with a new 5-speed manual transmission. (The RS is only available with this manual gearbox.) Benefiting from the know-how Mitsubishi Motors has accumulated in the motorsport arena the new manual gearbox features a greater torque capacity to handle the higher torque generated by the new turbocharged engine without growing in size. First to fourth gears use close ratios. 1st gear uses a lower ratio than previously for better standing acceleration while 5th gear uses a higher ratio for more comfortable high-speed cruising. The new transmission uses multi-cone synchronizer rings on all gears for smoother shifting and a more positive shift feel as well as for improved durability.
Body
Mitsubishi Lancer Evolution X's new platform achieves significant increases in body stiffness, with gains in torsional and flexural stiffness of 40% and 60% respectively over Lancer Evolution IX MR. This results in better handling stability and crashworthiness, as well as in improved ride and in reduced vibration and noise, to realize levels of quality and comfort that befit a new-generation sports sedan.
Mitsubishi Lancer Evolution X's wider track and longer wheelbase not only create a more spacious living space but also bring improved stability and ride. Other factors contributing to the new model's improved handling include its lower center of gravity stemming from the lower powertrain, and better front/rear weight distribution resulting from the lower engine weight, a front overhang that is 20 mm shorter than on the Lancer Evolution IX MR, and the transfer of the battery to the trunk.
To reduce weight and lower the center of gravity, aluminum is used in the roof panel, front fenders and the rear spoiler frame structure.
Suspension & tires
While based on the MacPherson strut front and multi-link rear suspension arrangement used on previous models in the series, Mitsubishi Lancer Evolution X features a revamped suspension layout with wider tracks and 18-inch tires. Geometry optimization and greater stiffness in the mountings maximizes the contact patch and allows S-AWC to perform to its full potential as well as bringing improved straight line stability, cornering and ride.
GSR comes standard with 245/40R18 wide and low-aspect tires on 18-inch Enkei 12-spoke high-rigidity cast alloy wheels. 18-inch BBS lightweight alloy wheels are also available as a factory-fitted option for GSR and add a distinctive custom touch with a luster finish.
GSR comes standard with brembo 18-inch front and 17-inch rear ventilated disc brakes. The increased disc size improves stopping power and fade resistance as well as improving brake pedal feel.
The factory-fitted High Performance Package comprises the Bilstein single tube shock absorbers and Eibach coil springs used on Lancer Evolution IX MR. It also includes brembo 2-piece disc brakes that realize a saving of 1.3 kg at each wheel and high performance tires with stiffer walls and better grip. This package brings further improvements in grip, steering response, stability and cornering.
4WD system (S-AWC)
The GSR trim level comes with Mitsubishi Motors' own 4WD vehicle dynamics control system S-AWC (Super All Wheel Control) standard. For Mitsubishi Lancer Evolution X, Active Stability Control (ASC) has been added to the ACD, AYC and Sport ABS component systems featured in previous Lancer Evolution. S-AWC uses integrated management of these systems to exert high-precision control on drive torque and brake force at each wheel to enhance cornering and stability under all conditions from everyday driving to emergency evasion; thereby producing vehicle behavior that faithfully reflects driver intent. S-AWC offers three operating modes - TARMAC for dry, paved surfaces; GRAVEL for wet or unmade surfaces, and SNOW for snow covered surfaces - allowing the driver to select the mode best suited to current road surface conditions and realize greater stability.
ACD (Active Center Differential)
The Active Center Differential uses an electronically-controlled hydraulic multi-plate clutch to optimize front/rear wheel torque split and thereby produce the best balance between traction and steering response.
AYC (Active Yaw Control)
AYC uses a torque transfer mechanism in the rear differential to control rear wheel torque differential for different driving conditions and so limit the yaw moment that acts on the vehicle body and thus enhance cornering performance. AYC now features yaw rate feedback control using a yaw rate sensor to more accurately determine the cornering dynamics on a real-time basis. And the addition of braking force control allows the system to realize vehicle behavior that more closely mirrors driver intent.
Sport ABS (Sport Anti-lock Brake System)
ABS allows the driver to maintain directional control and keeps the vehicle stable by preventing the wheels from locking under heavy braking or when braking on slippery surfaces. The addition of yaw rate sensors and brake pressure sensors to the Sport ABS system has improved braking performance through corners.
Active Stability Control (ASC)
The ASC system stabilizes vehicle attitude while maintaining optimum traction by regulating engine power and the braking force at each wheel. ASC elevates vehicle stability by suppressing skidding in an emergency evasion maneuver or as the result of other sudden steering inputs. It also improves traction under acceleration by preventing the driving wheels from spinning on slippery surfaces.
Maserati GranTurismo
The new Maserati GranTurismo, styled by Pininfarina, makes its worldwide debut at the Geneva Motorshow.
The Maserati GranTurismo is a muscular and sporty car, that can be enjoyed every day and at the same time is engaging for the driver. Its excellent handling and sportiveness makes it a point of reference in its category. The Maserati GranTurismo is built with particular attention to comfort, choice of materials and details and with enough room for four people, as only Maserati can do.
The new Maserati GranTurismo is a high-performance sports car, exciting to drive with a 4.2 liter V8 engine, delivering 405 HP, and a weight distribution of 49% at the front and 51% at the rear. It is fitted with an automatic gearbox and equipped with an adaptive control system which adjusts the gear-shifting mode to the driving style and the driving conditions.
Maserati's tradition of the Gran Turismo concept dates back to 1947 when the Trident Company, following its clients' demand, unveiled at the Geneva Motorshow its first Gran Turismo, the A6, designed by the great Pinin Farina. It was the first Maserati road car and was produced in 58 units. The car was acclaimed by the automotive press for its advanced technical content and for its avant-garde style solutions.
The new model name - Maserati GranTurismo - is not incidental. Once again, the partnership between Maserati and Pininfarina gives birth to a car that is able to generate emotions and sets itself apart from competitors, due to the technique with which it is built and its unique style.
The new Maserati GranTurismo represents a further step towards the completion of the Trident product range, following the worldwide launch of the Quattroporte Automatic at the 2007 North American International Auto Show in Detroit
Ferrari 458 Italia
While it's true that every Ferrari is innovative by definition, it's equally true that in the course of the Prancing Horse's history, certain cars have marked a genuine departure from the current range. This is very much the case with the Ferrari 458 Italia, which is a massive leap forward from the company's previous mid-rear engined sports cars.
The new model is a synthesis of style, creative flair, passion and cutting-edge technology, characteristics for which Italy as a nation is well-known. For this reason Ferrari chose to add the name of its homeland to the traditional figure representing the displacement and number of cylinders.
The Ferrari 458 Italia is a completely new car from every point of view: engine, design, aerodynamics, handling, instrumentation and ergonomics, just to name a few.
A two-seater berlinetta, the Ferrari 458 Italia, as is now traditional for all Ferrari's road-going cars, benefits hugely from the company's Formula 1 experience. This is particularly evident in the speed and precision with which the car responds to driver inputs and in the attention focused on reducing internal friction in the engine for lower fuel consumption than the Ferrari F430, despite the fact that both overall displacement and power have increased. However, Ferrari's track experience makes its presence felt in the Ferrari 458 Italia not only in terms of pure technological transfer but also on a more emotional level, because of the strong emphasis on creating an almost symbiotic relationship between driver and car. The Ferrari 458 Italia features an innovative driving environment with a new kind of steering wheel and dashboard that is the direct result of racing practice. Once again input from Michael Schumacher - who was involved from the very start of the Ferrari 458 Italia project - played an invaluable part.
The Ferrari 458 Italia's Pininfarina design provides further evidence of the complete departure from the past that this new car hails. The Ferrari 458 Italia has a compact, aerodynamic shape, underscoring the concepts of simplicity, efficiency and lightness that inspired the project. As with every Ferrari, the car's styling has been very heavily influenced by the requirements for aerodynamic efficiency, as can be seen from the downforce of 140 kg at 200km/h generated by the new model. The front features a single opening for the front grille and side air intakes, with aerodynamic sections and profiles designed to direct air to the coolant radiators and the new flat underbody. The nose also sports small aeroelastic winglets which generate downforce and, as speed rises, deform to reduce the section of the radiator inlets and cut drag.
The new 4499 cc V8 is the first Ferrari direct injection engine to be mid-rear mounted. It has a very low piston compression height typical of racing engines which contributed to achieving its compression ratio of 12.5:1. Equipped with the traditional flat-plane crankshaft, the engine delivers 570 CV at 9000 rpm and, with an outstanding power output of 127 CV/litre, sets a new benchmark not only for the whole Ferrari range and the history of company, but also for the entire market segment. Maximum torque is 540 Nm at 6000 rpm, over 80 per cent of which is available from 3250 rpm. Specific torque is a record 120 Nm/litre. However, what is truly extraordinary is the amount of torque available while still maintaining high levels of power at low revs.
The car's soundtrack is also typical Ferrari, with an exciting, powerful growl emerging from the engine before it channels through to the exhaust's three rear tailpipes.
The Ferrari 458 Italia is equipped with the seven-speed dual-clutch transmission which increases performance whilst providing very smooth shifts even at full throttle. The engineers have developed specific, sportier gear ratios to match the power and torque curves of the new V8, guaranteeing high torque even at lower engine speeds and allowing the car to reach its maximum speed in top gear.
This new Ferrari is also a major leap forward when it comes to cutting emissions. Despite the fact that the new engine is significantly more powerful than the V8s that preceded it, the Ferrari 458 Italia produces just 320 g/km of CO2 and fuel consumption is 13.7 l/100 km (combined cycle), the best in the entire segment
