Elon Musk presumably hasn't yet quite worked out that this is a war of words only one side can possibly win.

On the one hand, anything Martin Eberhard says about Elon Musk has no implications for himself or whatever he does next.

On the other hand, Elon Musk's comment about Martin Eberhard begs the question "so, you're trying to sell us a car designed by the worst individual you've ever had the displeasure of working with?"

Whoops. Elon, open mouth, remove foot, then close mouth again and leave it that way.

I notice you've only shown it from the rear this time. The boat race aint no Paris.

"Fisker in short order has announced a deal with GM to supply it with 260bhp 2.0L DI Ecotec engines for its Karma four-door sports saloon"

An electric car. With a 260hp petrol engine.

Ho yus. Looks like another Prius - perfectly conventional car with a small battery for feel-goodery and to evade various taxes.

Looks absolutely gorgeous.
