Do you know which are the best kept secrets among automakers? Their future top models! But you will say why do they still want to develop supercars if people are doing their best to find Eco, Blue and hybrid solutions? Well simple: because supercars is what keep a maker alive, and from the edge of the top models will also benefit the subordinate vehicle series.

And supercar will always have success, no matter how many restrictions there will be! Lets be serious now, if you had the money what would you buy: a Prius or an Enzo (or any other combination you prefer)?

Lets take BMW for example, they have already trademark the "M10" name for a future supercar that is supposed to be a replacement for the legendary BMW M1, built between 1978 and 1981.

The M1's successor will be powered by a ten-cylinder twin turbo-charged engine and will feature direct fuel injection. The performance target: 625 hp and a top speed of 400 km/h!

BMW will also offer an entry-level version that will be powered by twin turbo a 4.4 liter V8 engine that delivers 450 hp.

The M1's successor will debut in the next 24-36 months and will be priced between 150.000-300.000 euro depending on the engine.
