Audi A1 Quattro revealed

The Audi A1 quattro is powered by the 2.0 TFSI engine. The 1,984cc, four-cylinder engine combines gasoline direct injection with turbocharging in the classic Audi manner. Among its highlights are the adjustable intake cam shaft and the two balance shafts, which ensure smooth operation. Maximum torque of 350 Nm is continuously available between 2,500 and 4,500 rpm, and peak power 256Ps is developed at 6,000 rpm.

Every detail of the sporty, sonorous four-cylinder engine has been optimized for high performance and low fuel consumption. Common rail injection, a turbocharger with intercooler and a regulated oil pump are just a few examples. The Audi A1 quattro is expected to consume on average less than 8.5 liters of fuel per 100 km. Yet it performs like a top-notch sports car: The standard sprint takes just 5.7 seconds, and top speed is 245 km/h.

The 2.0 TFSI delivers its power to the quattro permanent all-wheel drive system via a precisely shifting six-speed transmission, bringing Vorsprung durch Technik to the small-car class. The heart of this system is an electronically controlled, hydraulically actuated multi-plate clutch whose package of plates rotates in an oil bath.

During normal driving, the clutch sends most of the engine's power to the front wheels. If traction decreases there, the clutch can transfer torque steplessly to the rear axle in just a few milliseconds by forcing the packages of plates together by a defined amount. A pressure reservoir helps the electric pump to develop the oil pressure. If a wheel on one of the axles should slip, it is braked by the electronic differential lock (EDL).

The placement of the multi-plate clutch at the rear axle provides for a harmonious distribution of the axle loads, and the chassis of the Audi A1 quattro has been adapted to the dynamics of the drivetrain.

The infotainment equipment likewise leaves nothing to be desired. It includes a CD changer, a digital radio tuner, the Audi music interface and MMI navigation plus. The Bose sound system drives 14 speakers with 465 watts of power; the woofers in the doors are indirectly lit with light guide LEDs. Audi connect uses the Bluetooth online car phone to connect to the Internet and deliver special web services, including Google Earth, to the car. Passengers can also connect their mobile devices to the integrated WLAN hotspot.
