Concept Car of the Week: Oldsmobile Aerotech (1987)

In late 1984, Oldsmobile management had so much confidence in the potential of its new inline four-cylinder engine Quad 4, that a small team was assigned to the creation of the Aerotech, a research vehicle designed to demonstrate the engine's performance by setting a new world speed record. Ed Welburn, then assistant chief designer, was mostly working on the 1988 Cutlass Supreme but his passion for race cars made him the ideal candidate to be handed the assignment by Oldsmobile 2 studio's chief David North. Inspired by Le Mans racers such as the Porsche 917LH and Jim Hall's Chaparrals, he designed a long, flowing car that immediately seduced design director Chuck Jordan and GM management.

Aston Martin Coupé Zagato Centennial and Spyder Zagato Centennial

American car collector Peter Read has commissioned a pair of Zagato-bodied Aston Martins that coincide with the British marque's centenary. The DBS Coupé Zagato Centennial and DB9 Spyder Zagato Centennial are the hard- and soft-top siblings are the latest in a long line of collaborations between the two companies. But while many have been – an admittedly more exuberant – expression of contemporary Aston design language, the Centennials have a stronger individual identity with an almost sedan-like aesthetic with forward-leaning noses and long Kamm tails.

Volkswagen puts a price on the VW Polo BlueGT

The Volkswagen Polo Blue GT – a warmed over Polo – will cost from £17,400 for the 1.4-litre 138bhp 6 spd manual. The Polo Blue GT gets the 1.4 TFSI engine with 138bhp so the little Polo can row along well enough, but it also get cylinder deactivation for when you’re not blatting from traffic light to traffic light to endow the Blue GT with official average economy of 60.1mpg (or 62.7mpg if you opt for the DSG ‘box). When you’re not worried about being parsimonious with your fuel the Polo GT skips along to 62mph in 7.9 seconds and handles well enough thanks to the Polo’s already decent setup and a 15mm lower suspension.
