NISSAN SILVIA
Japan saw a new version of the Silvia (S15) in 1999, now boasting 250 hp (184 kW) from its SR20DET engine, thanks to a ball-bearing turbocharger upgrade, as well as improved engine management. The SR20DE (non-turbo motor) featured 165 hp (121 kW).
The S15 Silvia included aggressive styling inside and out, updating the previous Silvia styling in-line with modern car design trends. The body dimensions were reduced from the previous generation so that it would comply with Japanese Government compact class, which had an effect on sales of the previous model.
The S15 Silvia model lineup was initially simplified to just the Spec-S and Spec-R, both models offering an "Aero" variant with a large rear wing and side skirts/valances.
This generation of the Silvia was only sold in Japan, Australia and New Zealand but was available as a grey import in most other countries. In Australia and New Zealand the car was sold as the Nissan 200SX.
Within the Australian domestic market (AUDM), the S15 sold in 2 trim levels as noted above; Spec-S and Spec-R - however both models featured the SR20DET motor, albeit slightly detuned from the JDM spec cars. Nissan S15s were never officially sold with the naturally aspirated SR20DE engine in Australia or New Zealand. These two models were available at Nissan showrooms until the Nissan 200SX GT was introduced in 2002, the last year of production for the S15. Main differences here were namely the wheels being finished in a silver shadow chrome and updated larger rear wing.
Toyota SUPRA 1992
With this version Toyota took a big leap in the direction of a more serious high-performance car. Again using subframe, suspension,and drivetrain assemblies from the Z30 Soarer (Lexus SC300/400), test model pre-production started in December 1992 with 20 models, and official mass production began in April 1993. The new Supra was completely redesigned, with rounded body styling and featured two new engines: a naturally aspirated Toyota 2JZ-GE producing 220 hp (164 kW; 223 PS) at 5800 rpm and 210 lb·ft (280 N·m) at 4800 rpm of torque and a twin turbocharged Toyota 2JZ-GTE making 276 hp (206 kW; 280 PS) and 318 lb·ft (431 N·m) of torque for the Japanese version. The styling, while modern, does seem to borrow some elements from Toyota's first grand touring sports car, the Toyota 2000GT. For the export model (America/Europe) Toyota upgraded the Supra turbo's engine (smaller, steel wheeled turbochargers, bigger fuel injectors, etc.). This increased the power output to 320 hp (239 kW; 324 PS) at 5600 rpm and 315 lb·ft (427 N·m) at 4000 rpm. (326hp / 325lbft for Europe)
The turbocharged variant could achieve 0–60 mph in as low as 4.6 seconds and 1/4 mile (402 m) in 13.1 seconds at 109 mph (175 km/h). The turbo version was tested to reach over 285 km/h (177 mph), but the cars are restricted to just 180 km/h (112 mph) in Japan and 250 km/h (155 mph) elsewhere. European versions of the car also had an air intake or scoop on the hood. Drag coefficient is 0.31 for the naturally aspirated models and 0.32 for the turbo models but unknown with the rear spoiler.
The twin turbos operated in sequential mode, not parallel. Initially, all of the exhaust is routed to the first turbine for reduced lag. This resulted in boost and enhanced torque as early as 1800 rpm, where it already produced 300 lb·ft (410 N·m) of torque. At 3500 rpm, some of the exhaust is routed to the second turbine for a "pre-boost" mode, although none of the compressor output is used by the engine at this point. At 4000 rpm, the second turbo's output is used to augment the first turbo's output. Compared to the parallel mode, sequential mode turbos provide quicker low RPM response and increased high RPM boost. This high RPM boost was also aided with technology originally present in the 7M-GE in the form of the Acoustic Control Induction System (ACIS) which is a way of managing the air compression pulses within the intake piping as to increase power.
LANCER EVO
Mitsubishi unveiled a second concept car, the Prototype-X, at the 2007 North American International Auto Show (NAIAS).[21]
The Lancer Evolution X sedan features a newly designed 4B11T 2.0L (1998cc) turbocharged, all-aluminium inline-4 GEMA engine. Power and torque depend on the market but all versions will have at least 280 PS (206 kW; 276 hp). (JDM version), the American market version will have slightly more. The UK models will be reworked by Mitsubishi UK, in accordance with previous MR Evolutions bearing the FQ badge. Options for the UK Evolutions are expected to be between 300 hp (220 kW) and 360 hp (270 kW).
Two versions of the car are offered in the U.S. The Lancer Evolution MR, with 6-speed Twin Clutch Sportronic Shift Transmission (TC-SST). The other version is the GSR which has a 5-speed manual transmission system. The car also has a new full-time four-wheel drive system named S-AWC (Super All Wheel Control), an advanced version of Mitsubishi's AWC system used in previous generations.] The S-AWC uses torque vectoring technology to send different amounts of torque to the rear wheels.
It also features Mitsubishi's new sequential semi-automatic six speed SST twin-clutch transmission with steering-mounted magnesium alloy shift paddles. It has replaced the Tiptronic automatic transmission, hence the SST version replaced the GT-A version (which was used in Evolution VII and Evolution IX Wagon). A five speed manual gearbox will also be available. The new Lancer Evolution will also incorporate Mitsubishi's next generation RISE safety body.
The Evolution X went on sale October 1, 2007 in Japan, January 2008 in the USA, February in Canada (as the first version of Evolution in Canada) and in March 2008 in the UK. The Twin Clutch SST version was available in Japan from November 2007. Europe will follow with sales in May, GSR and MR version included premium Package. The introduction of the 2010 MR-Touring moved the car even further upscale. Leather and a Moonroof became standard while revising the rear spoiler to just a lip spoiler.
Japanese models
The engine is the 4B11T-type 2.0 litre inline-4 turbo engine. The Evolution X can accelerate from 0–100 km/h (4.5)- 4.7 seconds. Aluminum is used in the roof panel, hood, front fenders and the rear spoiler frame structure. The launch model's engine was rated at 280 PS (206 kW; 276 hp) @ 6500 rpm and 422 N·m (311 lb·ft) @ 3500 rpm. Following the repeal of the 276 horsepower Gentleman's Agreement in Japan, engine power was raised to 300 PS (221 kW; 296 hp) @ 6500 rpm beginning in 2009 model year.
Subaru impreza STI
Subaru introduced the "New Age" Impreza to Japan in August 2000. Larger in size compared to the previous iteration, the sedan increased its width by 40 millimetres (1.6 in), while the hatchback notably increased by just 5 millimetres (0.2 in)—placing the two variants in different Japanese classification categories. The coupe body style from the first generation did not reappear for the new series. However, the off-road appearance package that included contrasting-colored bumpers did carry over forward. Marketed as a separate model line, this North American-only variant was, as before, badged Subaru Outback Sport.
Naturally aspirated flat-four (boxer) engines comprised the 1.5-liter EJ15, the 1.6-liter EJ16, the 2.0-liter EJ20, and the 2.5-liter EJ25. Turbocharged versions of the 2.0- and 2.5-liter engines were offered in the WRX and WRX STI models. STI models featured a more powerful 2.5-liter turbocharged engine. WRX models featured a 2.0-liter turbocharged boxer engine until 2005, after which they switched to the 2.5-liter turbocharged engine.
Although the headlamp styling of the "New Age" Impreza was considered polarizing, improvements to the car brought greater mainstream acceptance. Subaru updated the Impreza's fascia in 2002 with more rectangular headlamps. In 2005, Subaru introduced a second facelift which introduced Subaru's new corporate face—including the controversial "jet intake and wings" grille design.
