Automotive manufacturers have been “cleaning up” their act so to speak in terms of their high performance variants, with announcement of the discontinuation of models like the Focus ST.

Fortunately for Lexus and the IS-F, this hasn’t been the case. The Toyota based company will be unveiling a revised 5.0 litre V8 that will be more compliant with the upgraded Euro 5 standard. The engine will still generate 423hp, accelerating the car to a 100 km/h in just 4.7 seconds. This goes on to reach an electronically limited top speed of 270km/h.

The 2011 model which will debut at the upcoming Paris Motor Show, will also feature exterior tweaks such as a new headlight design with LED daytime running lights, rear light design, a revised front grille, new alloy wheels along with new exterior colours. This is nothing new as they’ve also been made available for the regular IS with the F-sport package.

Inside changes include better support for the driver in the form of a new seat design, blue stitching for the leather upholstery and redesigned instrument clusters. A picture gallery is available after the jump.
