2012 Q5 Hybrid quattro

The hybrid quattro is distinguished by visual features on the outside. The tailgate, the fenders and the aluminum sill panel strips bear the hybrid lettering. The radiator grill is glossy black, and the tailpipes chrome-trimmed. Polar Silver, metallic is available for the exclusive paintwork.

The 2.0 TFSI in the has a displacement of 1984 cc (121.08 cu in). Its output is 155 kW (211 hp), with the maximum torque of 350 Nm (258.15 lb-ft) permanently available at 1500 to 4200 rpm. The 4-cylinder engine combines direct injection with turbocharging – typical for the Audi philosophy of downsizing, which replaces displacement by charging. The Audi valve lift system (AVS) further increases power, torque and efficiency by switching the stroke of the exhaust valves between two stages depending on the load and rpm.

The 2.0 TFSI has been overhauled in some respects for use in the Audi Q5 hybrid. The drive of the ancillary units has been dropped, and the crankshaft bearing and fine tuning of the turbocharger have been adapted to the specific demands. A secondary air system at the cylinder head makes sure that the exhaust gas treatment cuts in particularly fast. Integrated in the engine control unit, the so-called hybrid manager controls the efficient change and smooth transitions between the operating modes, and was fully developed by Audi alone.

A largely modified eight-speed tiptronic serves the power transmission without the aid of a torque converter. Its place is taken by the disk-shaped electric motor, combined with the multi-plate clutch operating in an oil bath – it couples and decouples the electric motor and the TFSI. The innovative decoupler operates with high precision, smoothly and quickly in any situation.

The highly comfortable and fast-shifting hybrid gear unit contributes significantly to the efficiency of the Audi Q5 hybrid – its eight gears are widely spaced. When the 2.0 TFSI is turned off, an electric pump maintains the oil pressure in the hydraulic system to safeguard the convenient start-stop feature.
