Renault to unveil Alpine-branded concept car at Monaco GP

Renault is set to unveil an Alpine-branded concept car at this weekend's Monaco Grand Prix. The A110-50 – so named to commemorate the fiftieth anniversary of the oh-so-pretty A110 rally car – is clearly a development of the 2010 DeZir concept car although with only one leaked image to analyze, it's difficult to know by what amount it has changed. Clearly it has been subjected to the addition of a myriad of additional details, surfaces, inlets, outlets and various pieces of racing addenda however that, on the little evidence we have, appear to have added drama to the detriment of the refreshingly non-aggressive nature of the DeZir.

General Motors designs windshield to see what the eye might miss

General Motors is developing a windshield display system designed to outline the edges of roads in fog and highlight a deer before it crosses into traffic. The system works by collecting information through vehicle sensors and cameras and projecting laser-generated images onto the windshield. It can also highlight road signs and tell drivers when construction is coming or when a desired exit is approaching.

Porsche race cars gather at Quail Lodge: Video

It was almost too serene, as the field of roughly 200 cars draped in loose silk car covers that greeted the crowd gave the impression of burying Porsches, not praising them. But things perked up with a group unveiling that revealed an outstanding collection of rare and unique racers, including many from the Porsche Museum and the Collier collection.
