In addition to the screaming 276-horsepower turbocharged/intercooled 2.0-liter engine that's common among all Evos, The MR offers a six-speed manual topped by a palm-filling aluminum shift knob; lighter, more subtly calibrated Bilstein shocks. The MR gets more, however. Immediately visible at the trailing edge of the roof is a patch of carbon fiber from which sprout a series of small fins. This is the vortex generator, and it reduces aerodynamic drag and increases the downforce generated by the huge carbon fiber rear wing. You may have seen similar devices on airplane wings.
