Design

KUZOVOsnovoy body is an aluminum frame, which are built light-bearing panels. The combination of profile sections with cast elements and the large panels reduced the total number of body parts. Fewer connections and advanced welding technology have led to the special rigidity. Recall that the opposition static torsional forces in the body of the new A8 to 60% more than the previous model, and light alloy construction and a half times lighter than comparable steel body. DVIGATELV-shaped ten-cylinder engine is a special version of the engine, mounted on the Lamborghini Gallardo. When you save during the diameter of the cylinders is increased, so has passed for the working volume of five liters. Power, compared to Gallardo, reduced to 50 liters. with. for increased torque, which "grew" by 30 Nm. Camber cylinder - 90 degrees. Crankshaft bearings are cast from gray iron to increase the heat and hardness of the aluminum crankcase. Forged connecting rods are combined with aluminum, oil-cooled pistons. In the collapse of the cylinder vibration of the first order balancer shaft calms, and all four camshafts can change the phase within 42 degrees. All shafts are maintenance-free units and chains on the rear end of the engine. And of course, technology triumphs FSI. TRANSMISSIYaPostoyanny wheel drive, which became the trademark Audi, is present on the S8. However, to match the orientation of the sports car and to improve the traction control center differential is made asymmetric. Under normal driving conditions the rear wheels account for 60% of torque, while the front - 40%. In the event of a change in road conditions completely mechanical differential distributes instantaneously share traction. The front axle in such a situation may account for up to 65% of the time, to the rear - up to 85%. Slipping wheels countered electronic differential lock and additional braking system. The standard Audi S8 is equipped with an automatic transmission function tiptronic. Switching gears manually is possible, with shift paddles. Top gear in the box has a lower ratio than the A8. Because of this dynamic can accelerate sportversiya and sixth speed. Suspension, steering, TORMOZAV Audi S8 uses conventional suspension kinematics A8 with special sports settings. In front of each side by four aluminum lever, rear - two trapezoidal. The suspension is much stiffer standard. Its height is consistent with normal air suspension, but can pnevmoelementy moving down the body by 20 mm. Because of this clearance varies from 125 to 95 mm. The gear ratio steering is reduced for better sensitivity. Brake disc diameter of 18 inches - standard equipment. On request is possible to install ceramic discs. Dynamic Stability ESP has special settings to work with "ceramics". SYSTEM BEZOPASNOSTIAudi S8 is equipped with switchable stability control system that operates with some delay and for a short time. She is able to remove a water film from the brake discs. In wet weather clamps invisible blocks to the disks occur automatically at regular intervals. The car is equipped with all possible kinds of airbags, seat belts equipped with pretensioners all but the front seats - active head restraints.
