The 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). The photos reveal flared fenders, an aggressive face and oddly stacked quad-tailpipes. According to The Car Connection, the IS500 will probably receive the 4.6-liter V8 from the new Lexus LS460 (wouldn't that make it an IS460?), which would up the power to around 380 horsepower. That's not enough in some cases to compete nose-to-nose with the Germans, but apparently Lexus says it won't get dragged into a horsepower war. We're sure it will find other ways in which to tussle with its German competition.
