Powerful New 3.0 TFSI Engine

The 3.0-liter, all-aluminum V6 engine in the 2011 Audi S4 benefits from supercharging to create 333 hp and 325 lb-ft of torque. The sizeable torque figure is generated over a wide range, from 2,900 to 5,300 rpm, making full power usable at any speed. The powerplant incorporates a number of Audi innovations to maintain class-leading fuel efficiency as well. FSI direct injection allows a high compression ratio of 10.3:1, a two-stage intake, dual intercoolers and a drive-by wire throttle all help the 3.0 TFSI achieve a remarkable 28 mpg highway (S4 3.0 TFSI quattro S Tronic).

Manual and Automatic Transmission

The 2011 S4 is available with a six-speed manual or the brilliant Audi seven-speed S tronic dual-clutch transmission, which allows the driver to enjoy power from the 3.0 TFSI supercharged V6 in nearly uninterrupted bursts - providing the perfect marriage of speed and comfort. The system works using dual clutches and twin input shafts, thereby allowing the computer to "predict" which gear the driver intends to use and prep the gear for action before it is selected. Also available on the S4 is quattro with Sport rear differential, which gives the S4 a new level of road holding ability, by actively controlling the distribution of torque between the two rear wheels, effectively overdriving the outside wheel in corners. This "forces" the front end of the vehicle into the corner, thus eliminating understeer and creating more attainable excitement for the driver. In addition, the Sport rear differential works with ESP during accident avoidance maneuvers to keep the S4 stable and composed in emergencies.

Suspension

While the smooth ride quality and athletic driving feel of the 2011 Audi S4 are enhanced by an incredibly rigid body design and the extensive use of lightweight materials, the advanced suspension is the real star of the show.

The 2011 Audi S4 offers extremely precise steering, thanks in part to a steering box located lower and further forward than on other comparable models. The effect is noticeable immediately, giving the Audi S4 a light and agile dimension. The innovative engineering combines with Audi dynamic steering to vary the ratio depending on vehicle speed. This equates to a more balanced system that offers quicker lock-to-lock feedback at low speeds and stable cornering when the vehicle is traveling faster

Options

The 2011 Audi A4 is available with a number of driver convenience packages designed to make the Audi ownership experience a pleasure. Among those, a Bluetooth/HomeLink package allows for a simple hands-free system and easy garage entry. The MMI Navigation plus package includes a hard drive based navigation system with center display, voice control, third-generation MMI and rear-view camera with rear park sensors. An available driver assist package includes parking sensors to alert the driver of approaching objects.

For the more sport-minded buyer, Audi offers both an 18-inch and a 19-inch sport package for the Audi S4 that includes unique wheels, summer tires, and attractive and supportive seats. A stiffer suspension and steering wheel mounted paddle shifters also are part of the equation, adding an extra level of driving flair to the already capable Audi S4. Even more significant is the return of Audi drive select - a system capable of adjusting a number of performance parameters on the fly to create a more precise driving experience. These include dynamic steering, suspension, and drivetrain settings.

quattro with Sport Differential

quattro with Sport differential goes a step beyond the already capable quattro all-wheel drive by controlling torque distribution between the two rear wheels, effectively changing the balance during cornering by overdriving the outside rear wheel. This causes the front of the car to "tuck into" corners, and eliminates understeer. The system reacts in less than 100 milliseconds - quicker than even ESP - and amazingly works without using the brakes whether or not the gas is applied.
