Driven: BMW i8

When BMW unveiled the Vision EfficientDynamics concept at the 2009 Frankfurt motor show, we wrote: "for our money, it's the first time a major carmaker has really attempted to communicate ‘green' technology in an aesthetic sense." Fast-forward five years and we've swapped the show halls of the IAA for a beauty spot on the north-west coast of Scotland. And, while the car's name has changed to i8, our sentiment towards this genre- and era-defining car remains. Admittedly the production car's design execution hasn't received the universal praise of its concept forebears, but, on a remote outpost of the British Isles, a Protonic Blue i8 couldn't look more exotic.

BMW M5 F10M (2011) track test video

BMW M has released new video footage of the upcoming F10M M5 performance testing at the BMW Miramas test centre in southern France. Is this BMW M5 video worth risking a sneaky peek at the office? If you like the M5 or fast cars in general, yes. Compared to previous entries in the M5 teaser video campaign this one shows the BMW M engineers creating enough wheelspin and oversteer to make us think that they're auditioning to work in the motoring media. The video, at nearly four minutes long, shows M5 prototypes largely stripped of camouflage sheeting being put through their paces on the test circuit, as well as undertaking some low speed incline testing on a 32 degree gradient. What we can see conforms with the M5 Concept shown at the 2011 Shanghai motor show.Apart from the aforementioned tyre abuse, you also get clear shots of the new M5's instrument panel, showing the M-DCT transmission's shift mode selector and adaptive damping display.

Concept Car of the Week: Bertone Alfa Romeo Carabo

It might sound unbelievable today, but despite its racing pedigree and a voluptuous body designed by Franco Scaglione, Alfa Romeo was struggling to sell the outstanding 33 Stradale. Its heavy price tag was far above that of a Lamborghini Miura and also 120hp less powerful. By 1969, production was discontinued and only 18 examples had been made.
