Subaru BRZ (2012) insurance groups announced

Subaru has announced the BRZ sports car will fall into insurance group 30, with higher-end SE Lux models in group 31. How does the Subaru BRZ's insurance compare to its rivals? Tricky question, since the BRZ, as a £25k, rear-drive 2+2 coupe, doesn't have much in the way of brand new, direct rivals (save for its Toyota GT86 sister of course).

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.
