New Audi S4 sedan and Avant is revealed in detail, including engine specs, power figures and indicative pricing. Looks like another winner from Audi.

Audi S4, new for 2009 and ready to play. Two versions of the same car, a sedan capable of carrying people and luggage, and an Avant, just as capable and adding skis plus family dog. At the heart of the S4 is a throbbing petrol V6 displacing 3.0-litres in size. In their wisdom, Audi saw it fit to install a supercharger to compliment this V6 motor, thereby creating a bahnstormer of 245kW/ 333 hp. Maximum torque is quoted at 440Nm. Although supercharged, the S4 is badged TFSI like the turbo charged Audis.

Driving this power to all four wheels is quattro, which under normal guise transfers 40 percent of torque to the front and the rest to the rear, but can transfer a range of torque at the speed of milliseconds, depending on road conditions. Taking all this power in their stride are the two gearboxes offered; a standard 6-speed manual and an optional 7-speed double clutch S Tronic.

Suspension is a five five-link front axle and a self-tracking trapezoidal-link rear axle. It uses several components made from aluminium, so it is quite light as well. An optional sport differential adds to the handling excitement, especially on take-off. Here the S4 sedan achieves a sprint time of 5.1 seconds from 0 – 100km/h, while the Avant goes slightly slower with a time of 5.2 seconds. Both versions are said to be limited to 250km/h, but we know Audi has on occasion, understated this particular figure.

S4 comes kitted properly to lay its claim as the current leader of the A4 pack, until the arrival of the RS 4. Sporting that muscular look thanks to special aprons, sill trims, rear spoiler, quad tail pipes, 18-inch light-alloy wheels and the trademark aluminium-look side mirrors, the S4 is distinctively different from other models in the range. Interior convenience is provided in packages, including MMI, various sound system choices that include the top-of-the-range Bang & Olufsen, Bluetooth and iPod interface. At 50,950 Euros for the basic manual sedan, the S4 offers a very attractive overall package for the family-oriented person with thrill-seeking tendencies.
