Watch Tesla Model S testing new titanium armor

In a missive signed by Elon Musk himself, Tesla announced it would be adding titanium plates and aluminum deflectors to all new Model S sedans and offering free retrofits for the 20,000 or so existing EVs. The company earlier offered an over-the-air software update to raise the ground clearance of the Model S so the car would be more likely to clear dangerous road debris. The actions were in response to well-publicized fires in the electric luxury sedans.

Record expected for Auto Union sale

By James Mullan Motor Industry 07 February 2007 09:21 A rare 1939 Auto Union Type D grand prix car is tipped to tear up the record books this month when it goes under the hammer – for an estimated price of up to £7.8 million. Auto Union developed the Type D racing car with a mid-mounted 3.0-litre 12-cylinder engine; in 1939, it was modified with the addition of a twin supercharger, increasing power 420bhp to 460bhp – enough for a top speed of 205mph. This particular car won the French and Yugoslavian Grand Prix in 1939, but at the end of the Second World War it was transported from East Germany to the former Soviet Union by Russian occupation forces as spoils of war.
