Audi SQ5 TDI arrives at Le Mans

The Audi SQ5 TDI – a 309bhp diesel Q5 – is revealed at Le Mans as the first Audi S model with a diesel engine. It’s quite appropriate that the first diesel S Model from Audi has arrived at Le Mans in the shape of the Audi SQ5 TDI, where Audi are expected to dominate in diesel-engined cars. It also shows that Audi are aware that powerful diesel compact SUVs are a must have in today’s car market, and they’ve got in first with a proper barn-storming diesel Q5 before a Range Rover Evoque Sport with perhaps the 3.0 litre V6 diesel or a BMW X3 M40d arrives.

Chevrolet Colorado concept

General Motors' Chevrolet brand is previewing the next generation midsized Colorado pickup truck in concept form at the Bangkok International Auto Show. The venue was chosen to debut the truck due to the Thai market's prevalence – it is the world's largest market for midsize pickups. Despite being a show vehicle, the basic proportions and form are said to convey the vision for the next-generation Colorado, whiuch is said to build on Chevrolet's 'strong truck DNA and award-winning heritage.' With a design calling on the inherent strength of Chevy trucks, it is unsurprising to see the exterior boast a broad shouldered and squat demeanor.

The AutoWeek list: Foolish cars we should never have bought, but did

2001 Pontiac Aztek Our take: The most recent black eye to the General's style department. A car equivalent of the ubiquitous camel design, put together by a committee whose members obviously didn't speak to each other. 1999 Isuzu VehiCROSS Our take: We don't doubt this Japanese ute's off-road prowess, but its goggle-eye front and corrugated steel door ripples were enormous design miscues.
