Videos: Chris Bangle shares his views on design and the future of car design

Chris Bangle is a man that needs no introduction on these pages. Both revered and castigated, Bangle's work has undoubtedly been influential for a generation of designers. His unconventional practices – employed at a time when design was still largely segregated from other departments during the development process – yielded many avantgarde and contentious designs, but Bangle's fundamental understanding of the design process, creative vision and desire for change can never be cast in doubt. While Bangle shares his views on the future of the car in the video to the right, the video to the left provides an insight into the former BMW design chief's thought processes and gives us a glimpse into his home and studio in the Piedmont region of northern Italy.

BMW Concept5 X5 eDrive revealed. It’s a plug-in Hybrid X5

The BMW Concept5 X5 eDrive (pictured) will debut at Frankfurt The arrival of the BMW Concept X5 eDrive ahead of its debut at Frankfurt next month doesn’t preview and immediate addition to the X5 range of a plug-in hybrid, but it does show what will be on offer in a year or two. Just like yesterday’s Mercedes S500 plug-in hybrid, the X5 eDrive is another example of how car makers have developed their way round CO2 taxation levels by throwing electric motors at ICE engines to create a car that offers impressive emissions and economy on official tests. In the case of the X5 eDrive that means a four-cylinder twin power ICE engine (BMW aren’t saying, but we’re assuming its a petrol engine), a 94bhp electric motor and a lithium-ion battery under the boot all working together to produce an X5 that is capable (at least in official tests, which is all that matters) of 74.3mpg and emissions under 90g/km.

Audi shows S3 Sportback (2013) – but is a used S3 a better buy?

Here’s Audi’s S3 Sportback, the five-door version of the 296bhp Quattro hot hatch unveiled last year. The S3 Sportback takes 5sec flat to accelerate from 0 to 62mph, that’s one-tenth of a second quicker than Audi’s official figure for its three-door stablemate. That’s because the initial 5.1sec S3 time was only an estimate, and Audi’s subsequent tests have shown the three-door S3 actually dipping below five seconds in the 0-62mph sprint.
