Mercedes CLA employs a cat in new advert to demonstrate its aerodynamic shape (video)

It’s the Mercedes CLA sliding cat advert We’re not entirely sure that Mercedes has chosen to focus attention on a cat in a new advert for the CLA to dig at Jaguar’s mickey-take of its chicken advert for Magic Body Control, but it’s definitely the cat that’s front and centre, regardless of the motivation. With the new Mercedes CLA boasting exceptional aerodynamic credentials, Mercedes has employed a stunt cat to slide up and over the CLA to demonstrate just how slippery their new compact saloon is. Already shown on TV in the UK at the weekend (during the new series of Britain’s Got Talent), the moggie in question – William, apparently – glides effortlessly over the CLA’s slippery shape to a soundtrack playing Rossini’s Duetto buffo di due gatti (which you may not think you know, but you do).

Audi RS7 to lap Hockenheim – DRIVERLESS

Audi are taking an RS7 round Hockenheim completely autonomously Every car maker – from Mercedes to Volvo and Ford – is working hard to make autonomous driving a reality, and it looks like we’re just a few years away from seeing cars being driven by computers, with the driver relegated to passenger in many daily driving tasks. Now it’s Audi’s turn to demonstrate the progress they’re making with autonomous technology by taking an RS7 round the Grand Prix track at Hockenheim without a driver having control. It’s arguable that taking a driverless car round a track – even at race speed – is far less of a technological task than having a car running driverless through a cityscape with all its variables, but it’s an impressive demonstration nonetheless.

Other surprises include the quick charger that reduces charge times about 30 minutes and the inclusion of Sail Mode, which decouples the transmission from the engine to conserve fuel.
