A new MR edition debuts that features a six-speed manual transmission, BBS one-piece forged alloy wheels, Bilstein shocks and an aluminum roof for a lower center of gravity. The all-wheel-drive system for all Evos now includes a front helical limited-slip differential and electronic active center differential (ACD). All models get a power boost of 5 horsepower and 13 pound-feet of torque. A larger cupholder is new this year, and all models get aluminum side-impact bars (to save weight). The standard Evo loses its HID headlamps (now optional), and all Evos lose the intercooler water spray feature (due to packaging for the ACD). The MR and RS get an aluminum roof panel, and the RS also gets thinner sheet metal in the deck lid (again, to save weight). Inside, all models get a revised meter cluster to include the ACD display.
