Top Gear in Bolivia

Top Gear tackles the 'Road of Death' in Bolivia It may be Christmas, but at least we still get a new episode of Top Gear this Sunday – Episode 6 of series 14. But be warned; it’s on at yet another time slot – 7.45pm BBC2 – but that’s because it’s 75 minutes long instead of the regular one hour. This week is a Top Gear special with the boys tackling a journey across Bolivia in a quest to reach the coast of Chile.

This could be your first autonomous vehicle

While Google's autonomous fleet of robot cars prowls Silicon Valley and gets all the press, the first, or one of the first, truly autonomous vehicles you may ride in could be something like this: The humble, people-moving Navia. Developed by a French company called Induct, the Navia is ringed with laser beams (not frickin' laser beams. Ed.) that help it navigate through city streets or college campuses without the aid of a track in the ground, a rail or even GPS (GPS is not accurate enough, Induct says).

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.
