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.

Tesla asks NHTSA to investigate fires

In response to concerns following a recent accident which appeared to result from road debris damaging the underside of a battery compartment of a Tesla Model S, causing a fire in the engine compartment, the company has announced that it has requested that the National Highway Traffic Safety Administration conduct a full investigation into the fire incidents. In a blog post, Tesla CEO Elon Musk wrote the following about the investigation: "While we think it is highly unlikely, if something is discovered that would result in a material improvement in occupant fire safety, we will immediately apply that change to new cars and offer it as a free retrofit to all existing cars. Given that the incidence of fires in the Model S is far lower than combustion cars and that there have been no resulting injuries, this did not at first seem like a good use of NHTSA's time compared to the hundreds of gasoline fire deaths per year that warrant their attention." Tesla has also released a software update to the cars which will maintain their standard ride height at highway speeds, preventing the air suspension from lowering the car an extra inch at highway speeds for greater aerodynamic efficiency.

AA warns of automated penalties

DRIVERS are still suffering a year on from the time most wheelclampers were banned from operating in private car parks, according to the AA. Twelve months on, parking enforcement firms are reaping large sums from issuing automated "penalty" tickets. The AA said that while Communities Minister Eric Pickles is reining in local authorities who over-zealously use CCTV, private parking operators now rely heavily on this technology and automatic number plate recognition (ANPR) to watch drivers and issue tickets through the post when they put a foot wrong in parking areas.
