Despite the recent credit crunch and new car sales falling by the wayside the muscle car day are back, in more ways then you think. In the 1960s it was American automakers pulling their most powerful engines and installing them in smaller vehicles to create and fun factory built hot rod. And while U.S. car builders have come back with models like the Camaro SS and Shelby GT500, but it looks like things are taking shape across the Pacific as well. It turns out that the one cancelled F tuned version of the Lexus GS->ke439 luxury sedan has just received a new lease on life, much like the IS-F a GS-F will receive a high output power plant exotic to that chassis and be beefed up everywhere else to accommodate the extra ponies. The Lexus GS-F high performance four door will compete with models like Audi RS6, BMW M5, Cadillac CTS-V and Mercedes E63 AMG.

The Japanese magazine Best Car is speculating that a future Lexus GS-F will be powered by the same 4.8 Liter V10 piston pumper that can be found under the hood of the current Lexus LF-A->ke2181 super car. With a V8 being the largest engine offered in the current Lexus GS, a ten cylinder is next logical step, cranking out 553 HP and 354 lb-ft of torque from the 1LR-GUE, a 550 HP sport sedan sounds quite fun, however Toyota is going to have to shed a considerable amount of weight from the Lexus in order to work well with considerably less torque. However they know what they are doing, taking a decade to develop the LF-A, and we are sure that they have already taken that into consideration.
