Audi TT Sportback concept – it’s a 5-door TT: Paris 2014

Audi TT Sportback concept – it’s a 5-door TT Audi has long been the master of the niche, so it’s no real surprise they’re looking for ways to ‘extend’ the Audi TT in to a series of new niche models. The latest take is this, the Audi TT Sportback concept, which has arrived at the Paris Motor Show as a big brother to the TT Coupe, with an extra pair of doors and an extra 290mm in length. Audi has also played with the look of the TT Sportback, with a new hexagonal grill, new headlights and a new bumper up front and the new tail lights and smaller back window give the TT Sportback an individual look (well, as individual as an Audi ever gets).

Customers less satisfied with run-flat, low-rolling resistance tires

In non-April Fool's news, customers who buy cars shod with run-flat tires are nearly twice as likely to have to replace them as people with more conventional tires, according to a J.D. Power and Associates study. The poll also found that customers are also less satisfied with low-rolling resistance tires.

2014 Mercedes S Class LIVE reveal

The new S Class (W222) gets a bit longer than the current S Class (by 20mm), a bit wider (28mm) and a bit lower (25mm) but the wheelbase of the standard S Class stays the same at 3035mm with the long wheelbase S Class getting an extra 130mm for extra sprawling room. There will be a variety of engines on offer in the new S Class (from parsimonious 4-cylinders to mighty V12s) but we’re expecting at launch that just three will be on offer – the S350 diesel with a 255bhp V6, the S400 with a 300bhp V6 petrol and the S500 with a 4.7 litre turbo petrol with 450bhp. In terms of styling, Mercedes appear to have taken away much of the bulbous look of the current S Class and replaced it with a more flowing shape, but one that’s still very much S Class.
