Concept Car of the Week: Saab Aero X

In January 2005 Bryan Nesbitt, then-executive director of GM Europe Design, charged the 15-strong Saab Advanced design team in Gothenburg, Sweden, to create the "ultimate vision of the brand". The design team – led by head of Advanced Design at Saab, Anthony Lo – worked on a number of sports car proposals, which were considered 'the jet fighters of the road.' The chosen proposal by Alex Daniel was for a large, front-engined sports car that would become one of the most universally acclaimed concept cars of recent times. Of course the Aero X's door arrangement – complete with huge, forward-hinged canopy – is its party trick, but even without the theatrics the car's proportions, surfacing and graphics are exceptional.

Renault Alpine A110-50 at Monaco? Possibly, but surely this isn’t it.

Is this a new Renault Alpine (left), or a Photoshopped Renault DeZir (right)? The rumour mill says Renault will revive Alpine with a tribute to the A110 – the Alpine A110-50. But the photo doing the rounds surely isn’t it.

Ford trucks pulling it to the next level

With the heavy-duty truck segment heating up, Ford is breaking out some tough new vehicles and an upgraded 6.7-liter diesel engine. The second-generation 6.7-liter Power Stroke V8 turbo diesel packs a manufacturer estimated 440 hp with 860 lb-ft of torque. This is a gain of 40 hp and 60 lb-ft over the first-gen 6.7 oil burner.
