BMW Alpina B6 Bi-Turbo Convertible (2011) at the Frankfurt motor show

BMW’s M Division is busy readying M6 variants of both the 6-series Coupe and Convertible, but if you can’t wait until 2012 – or if you want a fast but understated Six – then Alpina has just the car for you.

The Toyota GT86 TRD Griffon (pictured) will be at the Goodwood FoS We’ve had a road-going version of the Toyota GT86 fettled by TRD and now we’re getting a track-focused version too. Just like the Toyota GT86 TRD, the Griffon version gets a makeover from Toyota Racing Division, and just like the road-going version – which costs £31,495 – the Griffon track version has to make do with the same 197bhp flat four engine the stock road car gets.

Mazda's rotary engine stalled, not forgotten

In fact, the 16X so far performs slightly better than Mazda's standard two-liter gasoline engine, said Mitsuo Hitomi, general manager of the Japanese carmaker's powertrain division.
