This Supra will use the V6-Hybrid link up of the Lexus GS450h (my wife's car) which is hugely powerful and smooth (335bhp; a 270PS petrol engine alongside a 180PS electric one). I imagine they'll tune that to get another 50 or so horses out of it. This is rear wheel drive and will be around the £50K mark.
The Lexus, the LFA-1, will be a V8 or a V10 and will be around the £80K mark, and also be hybrid, and possibly 4WD. And if you think that Supra looks a bit ugly...
However, while the Lexus will definitely happen, the Supra is being used purely as a teaser to see if potential customers are interested enough to generate a market for it. We're a long, long, way off production yet.
