Take a look on spy shots of new 2008 Lexus IS500. The Lexus IS500 will be a more potent version of the IS sedan that currently tops out at 306 horsepower in IS350 trim (that’s with a 3.5L V6). This prototype has all the sporty cues: an aggressive front air dam that appears to take inspiration from Lexus’ LF-A sports car, subtly integrated fender flares, and a deep rear bumper with uniquely stacked dual-exhaust tips.
The most logical engine powering this beast would be the 4.6-liter V-8 introduced in the new Lexus LS460, which, if in the same state of tune, would mean 380 hp and 370 lb-ft of torque.
