Audi's Q7 SUV has been given a new engine and trim level in an update for 2012.

Its new engine is a V6 3.0-litre carried across from the Audi A6 model and will accompany the 242hp 3.0-litre diesel that is already available in the Q7 range.

The new V6 engine is less powerful than the current model with a power output of 201hp from 450Nm of torque. With this power the engine delivers a top speed of 127mph and a 0-62 capability of 9.1 seconds.

However, this has the benefit of improving emissions and efficiency for one of Audi's largest cars on sale in the UK.

Emissions for the new V6 are 189g/km and it returns 39.2mpg. Although these are emissions are still high it is an improvement on the more powerful 242hp engine offered and a reasonable level for a large premium car.

This engine will also accompany the Q7's quattro four-wheel-drive and variable height air suspension system.

The Q7's new available trim level will be added to the Standard, SE and S line trims that are already available. The new is called the S line Plus and offers exterior features like 21" alloy wheels, privacy glass and metallic paint.

Inside, the trim offers new Verano leather upholstery, navigation Google Earth mapping, Audi Music Interface iPod connection and an Audi Parking System with a reversing camera.

Prices for the Audi Q7, with the Standard trim, start from £39,995 on the road, which is quite expensive. The other trims come in at an even higher price: SE £42,960, S line £44,620.

The new trim is the most expensive in the range and costs £49,120.
