Got it from MBworld: Lexus IS- F Test in Autocar today - MBWorld.org ForumsSubjective :-
Likes: Engine Note, Chassis balance, Strong Brakes, High Spec, Penchant for oversteer
Dislikes: Lack of proper LSD, Hesitent Gearbox, Flat seats, Fidgety ride.
More subjective impressions:-
Performance:- gearbox shuffles a lot to make most use of the 8 gears, engine note less aggressive than AMG and more contrived than M3 at high revs. Brakes good.
Handling and ride:- harsh patter at low speeds, chassis balance good with crisp turn in, extremely controllable oversteer handling, electronic LSD has not got smooth transitions though.
Styling and Interior:- Mark Levinson audio is superb though centre console finish excellent, interior does not feel special like C63 and M3, contrived exhaust
Summary "The IS-F is a credible effort for a company whose stock in trade is luxury and refinement, and there is much that Lexus has absolutely nailed. The V8 powperplant stands comparison to any of it's rivals and the overal balance of the chassis is wonderful. Those are the basics and they are spot on. In the end, then, it's the details that set the Mercedes C63 and BMW M3 apart from the IS-F. But they are the details that separate excellence from mere competence....Lexus has done well but can do better"
