Kia KV7 concept

Kia is clearly keen to grab the last of 2010's headlines by releasing this teaser render of its upcoming concept, the KV7, due to be unveiled at the Detroit auto show. The large crossover appears to preview a replacement for the Korean manufacturer's Borrego. While the exterior's clamshell tailgate, muscular wheelarches and Ford Explorer-aping lamp graphics (from this view, at least) may be directly relative to a production model, it's unlikely that the rear gullwing door openings will make the transition.

Audi RS7 Sportback refreshed with 190 mph top speed

Audi has fitted the RS7 Sportback with a series of mild styling changes only 18 months after its reveal at the 2013 Detroit auto show. Among the subtle visual modifications brought to the plush performance liftback is a lightly reworked front end. It features a restyled single-frame grille set within a slightly more structured bumper, bringing its appearance in line with less-powerful versions of the A7 Sportback revealed last week.

Audi A5 Coupe – the aluminium future.

Audi has built a lightweight A5 with aluminium body. Audi has taken a standard existing steel-bodied production car as its basis and utilised Audi’s Aluminium Space Frame which reduces the weight of the car body by at least 40% compared to a conventional steel bodied car. The result on the A5 is a drop in weight of 240 lbs (not quite the complete aluminium future Jaguar are working towards).
