Mercedes-Benz A-class patent renderings leaked

Mercedes-Benz unveiled a three-door concept version of its 2012 A-class at the New York and Shanghai auto shows in April, and images of a possible production model leaked this week via the European Patent Office. The renderings show a five-door hatchback version of the A-class concept with less aggressive styling. Its world premiere is said to be scheduled for the Frankfurt motor show in September.

Police Tape app can document traffic stops

In a video that looks like something cooked up by elementary-school students, the American Civil Liberties Union of New Jersey touts its new, free smartphone app called Police Tape. The application allows users to review their rights on the spot and to record both video and audio when stopped by police. Once recorded, files can automatically be uploaded to external servers, where they are retained and examined by the ACLU for possible civil liberties violations.

Tesla Model S goes up in price

The electric Tesla Model S – which won’t arrive in the UK until at least late in 2013 – is going up in price in the US and gets a spec change. The Tesla Model S is perhaps, just perhaps, the only really credible electric car so far; a luxury ‘Sports’ saloon car that offers range almost comparable to an ICE car and, it seems, prices that aren’t an awful lot different. That makes it a far more appealing prospect as a replacement for an ICE car than anything we’ve previously seen.
