We really haven't seen too much of the Lexus IS-F since the meanish blue beastie rolled onto the fog-filled set at the Detroit Auto Show. This past weekend we not only saw a sweet pearl white IS-F, but we witnessed that same IS-F setting the pace for the vintage Can-Am and IMSA racecars on top of shredding some tires between rounds. A couple of IS350 sedans were also on track during the event, which was presented by Toyota. The IS-F, powered by a 5.0-liter directed-injected V8 producing more than 400 horsepower and 350 lb-ft of torque, carved well ahead of its tires barking Lexus brethren, and sang a sweet V8 song through the quad-tipped exhaust. It really did sound that good. It's a fine appearance of a car we'll likely see in dealerships by early 2008.
