Mitsubishi Lancer Evolution IX MR
The Evolution IX MR (Mitsubishi Racing) represented the absolute pinnacle of the 4G63-powered Lancer Evolution series. With MIVEC variable valve timing, a Bilstein-damped chassis, and the most advanced version of Mitsubishi's Super All Wheel Control system, the Evo IX MR was the most complete and capable Evo ever built around the legendary iron-block four-cylinder engine.
The 4G63T engine, now in its final and most developed form, displaced 1,997cc and produced 286 horsepower at 6,500 rpm with 400 Nm of torque at 3,500 rpm. The addition of MIVEC (Mitsubishi Innovative Valve timing Electronic Control) on the intake camshaft improved both low-end torque and high-RPM breathing. The IHI turbocharger was matched to the MIVEC system's broadened powerband, and the result was an engine that felt equally willing to produce torque at 2,500 rpm as it was to scream to its 7,000 rpm redline.
The MR designation brought specific chassis upgrades: Bilstein monotube dampers, Eibach springs, and a six-speed close-ratio manual gearbox. The S-AWC (Super All Wheel Control) system integrated ACD (Active Center Differential), AYC (Active Yaw Control), Sport ABS, and the Super Sport ASC stability system. This array of systems worked together to provide extraordinary traction and adjustability — the car could be provoked into controlled slides yet snapped back to stability the moment the driver wanted it.
The Evo IX MR received subtle styling updates including revised headlights, a redesigned front bumper, and new wheel designs. The rear wing remained the Evo's visual signature, and the overall appearance was aggressive without being garish.
The interior featured Recaro bucket seats, a Momo steering wheel, and aluminum-accented controls. The cabin was functional rather than luxurious, reflecting the car's competition-focused priorities.
The Evo IX MR was the last Evo to use the 4G63 engine — a unit that had been continuously developed since the original Evo I in 1992. Twelve years of evolution had transformed a good engine into an exceptional one, and the Evo IX MR represented its ultimate expression. The subsequent Evo X used an all-new engine and platform, making the IX MR the end of an era.
Today, the Evo IX MR is universally regarded as the finest 4G63-powered Evo and one of the greatest turbocharged sports sedans ever produced.
The 4G63 in Evo IX MIVEC specification is the most developed version — still check for crankwalk and bearing wear. Six-speed gearbox (MR-specific) synchros must be checked. Bilstein dampers should be leak-free. S-AWC system including AYC must fully function. Service records essential. Unmodified MR examples are rare and increasingly valuable. The MIVEC system must be verified as operational.
Produced at Mitsubishi's Mizushima plant in Japan. The Evolution IX was manufactured from 2005 to 2007, with the MR variant introduced in 2006. Exact MR production numbers are not separately documented. The Evo IX was the final Evolution to use the 4G63 engine.
