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.

Pagani's trademark stylistic details are still present, such as the emphasis on carbon fiber and the quartet of exhausts.
