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.

Whichever side you come down on, the BMW 2-Series Active Tourer – previewed by the BMW Concept Active Tourer at Paris in 2012 – is a production reality and does look like it will fill very well the space in BMW’s range for a compact MPV. Despite looks that are almost the opposite of what you’d expect from a BMW – stubby nose and a high roof line; a proper BMW take on the Mercedes B-Class – the 2-Series Active Tourer still manages to exude BMW style, albeit in a more practical way to the rest of the range.
