An "F" version of Lexus' GS model is on the works and according to R&T, the GS-F will come with a 5.0L V8 engine (a V10 engine has been speculated in the past) producing 465 hp! It is estimated that it will hit 100 km/h in less than 4.5 sec. The mighty Lexus should therefore be able to challenge the Germans, BMW's M5 and MB E63 AMG.
But performance doesn't come only from a powerful engine, low weight is also crucial. Thus, Lexus aims to achieve a weight of around 1700 kg by incorporating aluminium and carbon fibre parts. The GS-F won't hit the markets any time soon, but it could make its appearance as early as 2012.
