Audi has released the full official details of the facelifted 2013 Q5 - its first updates since the initial launch in 2008. The highlights include a more refined engine range that is up to 15 percent more fuel efficient.

Exterior styling has been updated with minimal modifications to the grille, bumper and fog light surrounds while the headlights have been remodeled and incorporate both LED lamps and xenon plus units. The rear end meanwhile has been treated to modifications to the diffuser and tailpipes.

A choice of two diesel and three petrol powertrains are available with the compact crossover SUV. The diesel variants start with the frugal 2.0-liter TDI unit that generates 141hp (105 kW/143 PS) and 320 Nm (236 lb-ft) of torque while offering a fuel economy figure of just 5.3 liters/km (44mpg US / 53mpg UK). The 3.0-liter TDI meanwhile offers 241hp (180 kW/245PS) and 580 Nm (428 lb-ft) of torque.

The petrol options consist of a 2.0 TFSI with 221hp (165 kW/225PS) and 350 Nm (258 lb-ft) and a new turbocharged 3.0.liter V6 with 268hp (200 kW/272PS) and 400 Nm (295 lb-ft).

The final powertrain is for the hybrid variant of the Q5 line-up and is only available with the brand's quattro all-wheel-drive system. It couples the 2.0 TFSI with an electric motor to produce a combined output of 241hp (180 kW/245PS) and 480 Nm (354 lb-ft) of torque.

Pricing for the 2013 Audi Q5 facelift will start at €39,900 for the base model which is a bump of just €150 over its predecessor.
