Audi A8L

Audi A8L


The Audi A8 is a four-door, full-size, luxury sedan car manufactured and marketed by the German automaker Audi since 1994. Succeeding the Audi V8, and now in its third generation, the A8 has been offered with both front- or permanent all-wheel drive—and in short- and long-wheelbase variants. The first two generations employed the Volkswagen Group D platform, with the current generation deriving the MLB platform. After the original model's 1994 release, Audi released the second generation in 2002, and the third and current iteration in 2009.
Notable for being the first mass-market car with an aluminium chassis, all A8 models have utilised this construction method co-developed with Alcoa and marketed as the Audi Space Frame
A mechanically-upgraded, high-performance version of the A8 debuted in 1996 as the Audi S8. Produced exclusively at Audi's Neckarsulm plant, unlike the donor A8 model, the S8 has been available only in short-wheelbase form and is fitted standard with Audi's quattro

Initial release A8 (2010-)

 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


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).




A8 L long-term evolution broadband prototype (2011)

It is a version of A8 L demonstrating long-term evolution (LTE) broadband technology. Developed in collaboration with Alcatel-Lucent, the car's mobile broadband connection is a fourth generation (‘4G’) technology with data transfer speeds of up to 100Mbit/s.
During the 2011 Consumer Electronics Show in Las Vegas, Rupert Stadler, Chairman of the Board of Management of AUDI AG, announced that LTE technology would be used in cars by early 2011. The A8 L prototype was unveiled weeks later.

A8 L Security (2011–present)

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.First model included a W12 engine rated 368 kW (500 PS) and 625 N·m (461 lbf·ft), with delivery began in late summer 2011. An additional engine model with improved fuel efficiency went on sale in 2012.The vehicle was unveiled in 2011 Geneva Motor Show.
