The backlash among Evo enthusiasts was instantaneous. Once word came down that the 10th iteration of the Lancer Evolution (known as Evo X in Japan) was heavier than the outgoing 2006 model (Evo IX) yet possessed about the same level of power, rabid Mitsu fans began posturing that it wasn't only slower but, due to a beefier structure, more sound deadening, and new electronic aids like Active Yaw Control (AYC), also (gasp!) duller than the raw, scalpel-like IX. Heir apparent? If you paid attention to the bloggers who'd been speculating about the performance of the X even before the Concept X bowed at the 2005 Tokyo motor show, it was more like "error apparent."

To dispel (or confirm) these rumors, we grabbed an Evo X at the first opportunity and, in addition to subjecting it to our full battery of road and track analyses, we hauled it up to Reno-Fernley Raceway in the high desert of northern Nevada for a full day of track torture. With four miles of road course composed of 30 turns, 15 configurations, and enough elevation change to empty more stomachs than a Six Flags roller coaster, RFR is an ideal playground for assessing a rally-inspired street car. To raise the stakes, we brought along an Evo IX GSR (more commonly known as the straight IX or just IX) for a baseline comparison. We even had technical editor Kim Reynolds transport our long-term Evo IX MR to see how the new X would stack up against its most potent precursor (see sidebar). While your humble scribe and senior editor Ed Loh would hot-lap all three Evos, we enlisted the help of Erwin Nagl, chief instructor of the Pro Control Driving Academy at RFR and former DTM driver and BMW and Bondurant driving instructor, to slice and dice the best times. Grab your cutting boards; we got the blades....
