The third-generation Audi A8 (Typ 4H) was unveiled in Design Miami 2009 on 30 November 2009. It is based on the Volkswagen Group MLB platform, but retains the Audi Space Frame aluminium construction of the previous A8, making it the lightest all-wheel drive car in the full-size luxury segment, while also giving it best-in-class fuel economy. The quattro all-wheel drive system splits torque with a default bias of 40 percent front and 60 percent rear.
Early models include A8 4.2 FSI quattro (372PS), A8 3.0 TDI quattro (250PS), A8 4.2 TDI quattro (350PS). A8 3.0 TDI (204PS) was added later.
Initial internal combustion engine options comprise 4.2-litre Fuel Stratified Injection (FSI) petrol and Turbocharged Direct Injection (TDI) diesel V8s, with 273 kW (366 hp) and 258 kW (346 hp) respectively. A 3.0-litre V6 TDI with either 184 kilowatts (247 hp) or 150 kilowatts (201 hp) will be available later. A 6.3-litre W12 engine only for the long wheelbase model was made available in 2010, and compared to its predecessor it has a larger displacement and direct fuel injection. All engines are mated to the new eight-speed ZF 8HP automatic transmission. Although other Audi vehicles such as the 2010 Audi S4 and 2011 Audi A7 had switched from the 4.2L V8 to the 3.0L supercharged V6, the Audi A8 retained a higher-output 4.2L V8 as the base engine for the 2011 and 2012 model years in North America.
A8 L (2010-present)
German models went on sale in fall 2010. Early models include 3.0 TFSI quattro (290PS), 4.2 FSI quattro (372PS), W12 6.3 FSI quattro (500PS), 3.0 TDI quattro (250PS), 4.2 TDI quattro (350PS).

The A8 L Security features a core safety cell made from hot-formed armoured steel, aramide fabric, ceramics, special alloyed aluminium and multilayer glass. The car receives a high level of armouring, an emergency exit system, and a ballistic protection rating of VR7 – strong enough to, according to Audi, withstand a military hand grenade attack. In certain areas, the armouring on the Audi A8 L Security complies with the criteria for class VR 9 and VR 10.
