Concept Car of the Week: Dodge M4S PPG Turbo Interceptor (1985)

As a major paint supplier of Detroit's big three, PPG would commission every year a car to be used as a pace car in the Indy Car World Series. In 1984 Chrysler began the development of a mid-engined, rear-wheel drive car using an experimental powertrain. To avoid the costs of creating a whole new chassis, the M4S is based on a modified Huffaker tubular chassis with full roll cage taken from the Pontiac Fiero IMSA race car, only lengthened to a 100-inch wheelbase.

2015 Volkswagen Touareg price and specs – costs from £43,000

The 2015 Volkswagen Touareg (pictured) costs from £35k Volkswagen revealed a facelift for its biggest SUV – the VW Touareg – at the Beijing Motor Show in April which got the usual tweaks of titivated front and back and a new set of alloys to make it look fresher. Also in the mix, sadly, was the end of the very grunty 4.2 litre V8 diesel (and the hybrid in the UK) with VW deciding to concentrate on two flavours of V6 diesel and adding in new technology like post-collision braking, coasting and low-resistance tyres with air suspension to the mix. Now, with the 2015 VW Touareg due to go on sale on 27 August, Volkswagen has revealed prices and specs for the new Touareg.

Mercedes S400 Hybrid – and a facelift as well

Mercedes S400 Hybrid launched - and a facelift for the S Class Range [ad#ad-1] Mercedes has long held the ‘Best Luxury Car’ mantle, despite build quality issues in the early part of this century, but the competition, particularly from Audi and BMW has got stronger with each model change, so they have to keep upping their game (and the new Jaguar XJ may make them up it even further before long). So we knew it time for a facelift for the current S Class, but Mercedes has decided to link that with the launch of the first S Class Hybrid – the S400 Hybrid. The S400 Hybrid gets a 3.5 litre V6 petrol engine, which on its own delivers 279bhp, but linked to an electric motor it gets a 20bhp boost and a big jump in torque.
