At first glance, this latest iteration doesn't look all that different from a box-stock Evolution. The dark-gray forged BBS wheels are new, as are the complement of vortex-generating fins on the roof, but otherwise, it doesn't really scream extra performance. But it's there. There in the form of a retuned and slightly more powerful engine (276 bhp, 286 lb.-ft. of torque), a new 6-speed close-ratio gearbox, Active Center Differential (ACD), front helical limited-slip differential (LSD), Sport ABS and specially valved Bilstein shock absorbers. These improvements are evident from the first trip around the block. Gone forever is the wish I had another gear feeling of the current 5-speed, replaced by six tightly spaced ratios and a smoother, more positive shift engagement. Gone, too, is the standard Evo's often choppy ride. In its place, the Bilstein shocks have transformed how the suspension absorbs bumps, impacts and surface changes. The cabin feels much more isolated in the MR, yet the chassis sacrifices neither feedback nor grip along the way. The additional power may seem minor (5 more bhp, 13 lb.-ft. more torque), but on the road, the difference is more evident. A lighter, reshaped wastegate valve and larger turbine nozzle noticeably improve midrange punch and help the engine rev more freely from 3000 rpm to redline. Match that to the gearbox's closer ratios and the MR is never at a loss for neck-snapping acceleration. Expect 0-60-mph times in the mid-4s and the quarter mile in the low 13s. This extra velocity is ably handled by a chassis that boasts the aforementioned Bilsteins, front helical limited-slip differential (previously only available on the lightweight Evolution RS) and ACD. Working in concert with the new shocks, ACD and the front LSD make this Evo easier to drive quickly than the '04 car. This new setup keeps the tires more planted at speed (especially over bumps) and the front diff helps pull the nose around corners with greater conviction. The three ACD settings (Tarmac, Gravel, Snow) apply different software maps to the electronically controlled hydraulic differential, giving it slightly different parameters for distributing torque between the front and rear axles. For nearly all applications, Tarmac works best, but the other modes prove entertaining, especially at the track or on gravel, where they make it easier to rotate the car and slide it around a little (or a lot). The brakes have been upgraded to Sport ABS, an improved system standard on all '05 Evos (except the RS). Sport ABS monitors wheel and vehicle speed, and also incorporates data received from steering-wheel angle and lateral-g sensors to more effectively distribute braking force to each wheel. The extra sensors work as advertised, endowing the MR with an added degree of stability, especially under hard braking into a turn. To help compensate for the additional weight of the limited-slip front differential, weight has been trimmed in several critical areas: Each of the BBS wheels is 2.8 lb. lighter than stock, the side-impact door beams are now aluminum (saving 7.7 lb.) and the roof is also aluminum, shaving a further 8.8 lb. This adds up to a 27.7-lb. reduction, which cancels out the extra weight of the front LSD.
