The updated 2015 Audi A8 will feature more powerful engines, new assistance systems and Matrix LED headlights.

According to Audi, the design of the new A8 sedan has become even more expressive. The engine hood, the Singleframe grille and the front bumper are even more sculptured. Also, the A8 will feature optional headlights with Matrix LED technology, which sets new benchmarks with respect to design and technology. Additional features of the new headlights include intelligent cornering light, new-look daytime running lights and dynamic turn signals.

Audi offers the A8 on the German market with two gasoline and two diesel engines. These are the supercharged 3.0 TFSI with 228 kW (310 hp), the V8 twin-turbo 4.0 TFSI with 320 kW (435 hp), the highly efficient 3.0 TDI clean diesel with 190 kW (258 hp) and the extremely high-torque 4.2 TDI clean diesel, which produces 283 kW (385 hp) and 850 Nm (626.93 lb-ft).

Performance has increased with most engines. For example, when paired with quattro all-wheel drive, the 4.0 TFSI now accelerates the A8 from 0 to 100 km/h (62.14 mph) in 4.5 seconds.

When it comes to optional assistance systems, new in the A8 are Audi active lane assist, which makes slight steering adjustments when necessary, and the park assist system with 360-degree display, which handles steering when parking. In addition, the head-up display projects important data in the driver's field of vision on the windshield, according to Audi.

The new A8 is scheduled to arrive at German dealerships in November, says Audi. Prices in Germany start at 74,500 euros. The U.S. release date and specs haven't been announced yet.
