Porsche 911 Speedster arrives +Video

We’ve been expecting the first 911 Speedster from Porsche in almost a generation since we first reported back in June that we would see the Porsche 911 Speedster rocking in for Paris, along with the 911 GTS.

Tesla Model S outselling Chevrolet Volt & Nissan LEAF

Tesla never managed to make any money out of their electric Lotus – the Tesla Roadster – but it does look like they’re on to a winner with their electric  executive saloon, the Tesla Model S. Despite moans that the headline-grabbing sub-$50k Model S was never a reality – and a starting point of $70k – the Model S looks set to outsell the two most successful ‘alternatively fuelled’ cars – the electric Nissan LEAF and the range extender Chevrolet Volt – in the first quarter of 2013. Sales of the electric Nissan LEAF, which costs from $29k in the US, in the first quarter of 2013 were 3,965 units and the Chevrolet Volt, which costs from $40k, sold 4,421 units.

Mass production processes, packaging requirements and safety and regulatory constraints are just a few of the reasons why it is hard to make a car that looks truly different.
