The Japanese automaker Lexus unveiled a tuned version of their high performance IS-F sport sedan covered in a bright orange finish at the 2010 Tokyo Auto Salon. Much like the original IS-F Evolution, the Circuit Club Sport Concept focuses on dropping as much weight from the fast four door as possible to improve handling and acceleration without having to squeze any more power out of the 21st century V8. Although Lexus hasn’t disclosed exactly how many pounds were shed from the concept, with a vast assortment of items like the hood, fenders, roof, trunk, side skirts and rear diffuser all made from light weight carbon fiber, we are pretty sure that they met their quota.
On the inside, the cabin of the Circuit Club Sport Concept has also been adorned with the black baked composite material adding a bit more hardcore racer attitude to the concept IS-F with carbon fiber covering the door panels, center console, steering wheel and shifter. Meanwhile under the hood Lexus has left the 5.0 Liter V8 intact, however the addition of a lightweight free flowing exhaust system has raised output all the way up to 422 HP, more than enough to have some fun in this tuner IS-F.
