Driven: Citroën C4 Cactus

It wasn't our intention to hunt down random old Citroëns in the new C4 Cactus – on our first acquaintance with this new car in Amsterdam, they found us. The first was a beige 1971 DS Safari. It cruised by as we stopped for a photocall on the outskirts of the Dutch capital.

Ram introduces CNG-powered pickup

Aside from the Honda Civic Natural Gas, compressed-natural-gas-powered vehicles have usually been converted after the fact, generally for fleet use. Chrysler is hoping to carve out a niche in the corporate-pickup segment by selling a factory-built CNG Ram 2500 that can seamlessly switch over to gasoline operation when the natural-gas tanks run dry. The twin 4.6-cubic-foot CNG tanks (which store the equivalent of 18.2 gallons of gas) take up a section of the bed, while an eight-gallon gasoline tank provides fuel during start-up and then reserve capacity when the compressed tanks are tapped out, allowing the bruiser a measure of operational flexibility.

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.
