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.

GM to build Cadillacs outside the U.S.

General Motors CEO Dan Akerson said Tuesday that the company plans to begin building Cadillacs outside the United States by the end of 2012 as part of its plan to make GM's premium brand a true global nameplate. Akerson said overseas Cadillac production would reduce the risk of foreign-currency fluctuations and allow GM to better manage its supply chain. Although Cadillac long has been sold in China and other international markets, it's produced only in North America.

Aston Martin's Launch Edition Cygnets (2011)

Production of the Aston Martin Cygnet begins in just a few months' time, and the sports car company has announced two special editions to celebrate the launch of its new city car.

The Cygnet Launch Edition White is supposed to be about serenity, with Snow White paint, white diamond-turned alloy wheels, and white Aston badges on the outside, and white leather on the inside.
