Mercedes GLA 45 AMG Concept: Los Angeles Auto Show (video)

The Mercedes GLA 45 AMG Concept has been revealed in LA Over the weekend we had a teaser video from AMG for the GLA 45 AMG Concept, although Mercedes didn’t actually name it as such. But a GLA with the same powertrain as the A 45 and CLA 45 AMG is exactly what Mercedes’ AMG concept tease was, and it’s now been revealed in LA ahead of a likely debut in production form in 2014. The GLA 45 AMG Concept gets bold graphics – something buyers would be unlikely to want – and 21″ forged alloys painted matt black with a red rim and red brake callipers to shout its intent.

Driven: Fisker Karma

Even top-flight car designers are usually not known for their business acumen. So Henrik Fisker's announcement that he would build the "the world's first luxury plug-in hybrid" was met with some cynicism as he stood next to his Fisker Karma concept at the 2008 NAIAS in Detroit. Three years on and CDN is one of the first to get to drive Fisker Automotive's production Karma, a car so hot of the press this model is number three or four off Valmet Automotive's production line in Finland.

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.
