Company Profile:
A subsidiary of Volkswagen, the Audi Group, comprising the two brands Audi and Lamborghini, is one of the world’s leading carmakers in the premium and supercar segment. The core of the Company is the Audi brand. It offers its products under both the Audi and Lamborghini brands, as well as sells ...
The ratio of the cylinder and combustion chamber volume when the piston is all the way at the bottom (bottom dead center) to when the piston is all the way up in the cylinder (top dead center). A measure of the degree combustible gasses are pressurized and reduced in volume in a running engine.

Multitronic is a continuously variable transmission (CVT) with a steel link-plate chain running in tension in an oil bath between two pairs of bevel wheels of variable diameter. In addition, it permits an exceptionally wide range of effective ratios. The differential is located in the same compact housing as the transmission. There are no fixed gear ratios. The resulting smooth and powerful acceleration ensures a high level of driving comfort. There are also advantages when towing a trailer, thanks to the high torque available over the entire engine speed range. The design and the low weight of the transmission reduce fuel consumption. Manual gear selection mode is available, as with the 6-speed Tiptronic transmission and six simulated gear ratios can be selected. In the automatic mode on the multitronic that calculates the optimum gear ratio with the aid of a dynamic regulating program (DRP) according to engine load, the driver's preferences and driving conditions.

When the car equipped with convenience opening is locked or unlocked at the driver’s or passenger’s door, the power windows can be opened at the same time. All power windows open when the unlock button on the radio-operated remote control is held down. When it is released, the opening stops immediately. The same happens when the key is inserted into the door lock, turned to the open or close position and held there. The opening or closing process is interrupted as soon as the key is released.

Effective corrosion protection increases the car’s resale value. Audi bodies are made with fully galvanized sheet metal and have thorough wax flooding in cavities subject to moisture. Finally, we apply a paint finish consisting of many flawless layers. Corrosion protection is standard on every Audi model, except those in the A8 family (aluminum bodies do not need this protection).

All Audi models are extensively tested to achieve optimum safety prior to a car's availability in the market. First, virtual crash testing takes places via computer simulations. The following are tuned: * Stiffness of passenger compartment * Resulting acceleration curves * Occupant protection systems Next, the vehicle safety department conducts a whole series of crash tests – up to 30 different types, including frontal, side, rear-end and offset impacts and rollovers. The results of all these crash tests form the basis of the continuous development process to improve passive safety, which involves engineers and scientists as well as experts in accident medicine and accident research.

This electronic aid keeps the car moving at a constant speed, reducing stress on the driver particularly where speed limits must be observed, when towing a trailer, and on long trips. The system stores and maintains the speed selected by the driver. The set speed can also be manually increased or decreased. The cruise control can be deactivated with the “Off” switch or by pressing the brake or clutch pedal. (If desired, the car will resume the last speed set.) Note: For safety reasons, the cruise control should not be used in heavy traffic or under unfavorable road conditions (wet or icy roads, fog, ect.).
Industry:Automotive
The weight of an empty vehicle (without passengers or payload), but including oil, gas, coolant, and other standard equipment.

Various studies and the NHTSA recommend the use of daytime running lights, to improve driver visibility to oncoming traffic during the day. DRLs are mandatory in Canada. Several Audi models are now equipped with DRLs, which can be switched on or off based on driver preference. When the low-beam headlights are switched on by the light sensor or rain sensor, the daytime driving lights remain on but are dimmed to the brightness of side lights.

When a vehicle turns a corner, the inside wheels cover a shorter distance than those on the outside. To limit stresses and other wear in the drive train, the differential compensates for this difference. Since the rear wheels describe an arc different from the front wheels, an all-wheel-drive quattro also has a mechanical Torsen differential or a Haldex clutch to compensate for the difference in rotational speeds.
Industry:Automotive
The total volume of air displaced by all the pistons within an engine block. In general, the greater an engine's displacement, the more power it can produce.
