Mitsubishi introduced the Lancer Evolution IX in Japan on 3 March 2005 and exhibited the car at the Geneva Motor Show for the European market the same day. North American markets believed that the example given in the New York International Auto Show next month. The 2.0 L 4G63 engine has MIVEC technology (variable valve timing), and a revised turbocharger design to increase official output at crankshaft to 291 PS (214 kW 287 hp) and torque of 392 N m ( 289 lbs ft).
The USDM Lancer Evolution IX models: standard (Grand Sport Rally or "GSR" in some markets), RS (Rally Sport), SE (Special Edition) and MR (Mitsubishi Racing) has varied slightly in their performance capabilities. Subtleties unique to each model for variations in acceleration, handling and speed. The standard RS features excluded in the standard, SE and MR models (stereo system, power windows and locks, rear wiper, rear spoiler, inside the trunk and sound insulation). The result is a weight saving of more than 60 pounds (27 kg)
Although the RS is the lightest of the group, the Republic of Serbia failed to surpass the standard and IX MR around a circuit (if only by fractions of a second). This was intended to be a lack of a rear spoiler on the RS. In a sprint, the three models are all about even. The RS model was produced by teams rally racing and wanted a platform to build a race car. That is stripped of all amenities, and other improvements that drive the price for the features that the race teams would not be necessary.
The IX MR retains the features of the Evolution VIII MR like Bilstein shocks, a 6-speed manual transmission, a vortex generator on the roof, BBS forged wheels, HID xenon headlights, fog lights, accessory gauge package, " zero lift "kit, special emblems and an aluminum roof. All models continued to sport Recaro seats, Brembo brakes and steering wheel Momo. Additional revisions from 2005 include a closer relationship up to a 5-speed manual transmission, new lighter Enkei wheels on non-MR models, a redesigned interface with more efficient air dam (the most notable feature is the two canals small, oval to cool the intercooler pipes), and a new rear bumper with a diffuser undersurface to smooth the airflow coming out of the car to U.S. models do not. In an effort to reduce the price increase in the Evolution IX model,  HID headlamps are standard equipment is no longer on the base IX (nor were they standard on the 2005 VIII), and were only available in the package SSL (Sun, Sound and Leather), SE (Special Edition) and MR trims.
Three finishes are available for Japan, Asia and Europe. Although all models used the same 291 hp (214 kW, 287 hp) engine, the torque differs from one model to another. In Europe, however, the Evolution IX was announced that 280 hp (206 kW, 276 HP). The GSR produced 400 N m ( 295 lbs ft) of torque, while the RS and GT produced 407 N m (300 pounds feet).
* RS - "sports rally," revised 5-speed, aluminum roof, gauge pack minimal interior, LSD and a titanium turbine, magnesium, left hand drive option available.
* GT - revised 5-speed, this is basically the RS mechanically, but with some features of the GSR (parts, mainly the interior).
* GSR - 6-speed, Bilstein monotube shocks, aluminum roof, gauge pack Sayce (Super Active Yaw Control), and double-DIN radio (this is roughly equivalent to the USDM MR).
In the United Kingdom, the Evolution IX uses a different model scheme based on the power of the car. There were initially three models available: the FQ-300, CF-320 CF-340, each with approximately 300, 320 and 340 hp (254 kW) respectively. A CF-360 model was subsequently released as a successor to the Evolution VIII FQ-400. While the new FQ-360 produces less power than its predecessor, there were over 363 lbs torque feet (492 N m ) at 3200 rpm. The four models were designed to run on super unleaded petrol only. The MR FQ-360 also was published in a limited number (only 200) in the last year of production.
* CF-300, 320, 340 - 6-speed, Bilstein monotube shocks, AYC (Active Yaw Control), super unleaded petrol only
* CF-360 - 6-speed, Bilstein monotube shocks, AYC (Active Yaw Control), Ralliart Sports Meter Kit, carbon front splitter, Speedline alloy wheels, super unleaded petrol only
* MR FQ-360 - Turbo turbo finned aluminum alloy, titanium Speedline Turini alloy wheels, Privacy Glass, lowered Eibach coil springs (10 mm in the front / 5 mm in the rear), IX Interior D., super unleaded petrol only
Four models are available in the U.S.. All models used the same 286 hp (213 kW) engine.
* Standard - revised 5-speed, standard model
* RS - sports ralli, revised 5-speed, aluminum roof, gauge pack minimum inside, there are also radio
* SE - Special Edition, aluminum roof / Hood and front fenders, split seven-spoke forged aluminum BBS wheels in "diamond black" finish, HID headlights with integrated fog lights, red-stitched Recaro
* MR - 6-speed, Bilstein monotube shocks, split seven-spoke forged aluminum BBS wheels, aluminum roof, hood and front fenders, wide package, HID headlamps with integrated fog lights, vortex generator, and the distinctive Custom MR.
All American models are the same in power and performance. The only thing difference is the RS, Evo, which is 80 pounds (36 kg) lighter than the MR and SE models.
For the standard model, the Sun, Sound and Leather package adds a power sunroof, HID xenon headlights with integrated fog lights, a slightly different stereo headunit (with no integral amplifier), slightly better speakers in the front doors and shelf , 4.1 channel amplifier under the driver's seat, power trunk-mounted Infinity subwoofer, black leather seating surfaces Leather-trimmed door panels, slightly revised center armrests in the front and rear, and separate rear side headrests. This model deleted the GSR stellar mounted sunglasses holder to make room for the sunroof.
Philippines had the Evolution IX, until August 2008, which is offered in two trims, the entry-level RS offers a 5-speed manual transmission, Brembo 17-in. ventilated discs (4-Pot), 16-in Brembo ventilated drum in disc (2-Pot), and almost the same features of the GSR to the seat in the international version. The MR was the top-of-the-line segment, which offers nearly the same characteristic as that of MRI in the international verision seat. All are powered by a L4 2.0 4G63 MIVEC turbocharged.
