We've been hearing rumblings about a Lexus GS F for over two years, with the most recent report indicating that the maxed-out super sedan was put on hold until the economic climate reached a balmy 75-degrees. However, the rumormongers at Japan's BestCar seem to think that the GS F is back on track, and not only that, it'll be powered by a detuned version of the LFA's V10.
Although that sounds simply insane at first blush, the possibility of a 500+ hp V10 powerplant coincides with an initial report released way back in September of 2007. Not only that, but the GS F's closest competition -- the BMW M5 -- uses a bent-ten as well. However, even if Toyota is trying to spread out the costs of the LFA's development, with BMW's bahn burner about to get the twin-turbocharged V8 from the BMW X6/X5 M and Mercedes-Benz' decision to drop its 6.2-liter engines in favor of force-fed eights, it could be bad timing... or a cunning marketing move, depending on your motivational perspectives.
Speculation aside, if Toyota does pull the trigger and fit a reworked version of the 552-hp, 4.8-liter 1LR-GUE V10 into its staid sedan, expect the performance to strip the paint clean off it's swollen fascia while leaving you over $100,000 lighter in the process.
