Ingolstadt, Germany - Audi has given its Q7 Sports Utility Vehicle (SUV) a makeover with several styling changes and more efficient and cleaner engines.

Along with the 3.0 TDI, the car maker is offering a TDI clean diesel version with a consumption listed at 8.9 litres per 100 kilometres or 26.43 to the gallon (US).

Among the design changes is a new single-frame radiator grille

with vertical chrome bars contrasting with a black high-gloss finish. From the side, the vehicle has a more coupe-like roofline.

The interior features more legible instruments encircled by metallic frames and other details such as interior lights in the door linings.

The Q7 is available with six direct injection units, two of them petrol-powered and four diesel engines, including the V12 TDI. The 3.0 TDI has an output of 176 kW/240 hp with a consumption of 9.1 litres.

The optionally available TDI clean diesel is fitted with a complex exhaust gas recirculation system. It meets the strict LEV II Bin 5 US standard and already complies with the Euro 6 limits announced for 2014, according to the car maker.

The 3.6 FSI, a V6 with a small cylinder angle, has a power output of 206 kW/280 hp. Its average fuel consumption is 12.1 liters per 100 km.

All the engines are linked to a recovery system, which during braking and coasting phases, converts mechanical energy into electric energy and stores it in the battery. It reduces CO2 emissions by up to five grammes per kilometre, according to Audi.
