Audi S4

The new Audi S4 and Audi S4 Avant are top-class athletes ahead of their field. Their engine, the 3.0 TFSI, delivers 245 kW (333 hp) yet consumes only 9.7 liters of fuel per 100 km (24.25 US mpg). quattro permanent four-wheel drive, sports suspension and a high-performance brake system control the power reliably. With optional performance technologies - the seven-speed S tronic, the new sport differential and the Audi drive select dynamic driving system - both new S models from Audi are extending their lead even further.

It takes just two figures to comprehend the dynamic potential of the new Audi S4 and S4 Avant: 5.1 seconds for the sprint from zero to 100 km/h (62.14 mph) and only 4.4 seconds for the intermediate sprint from 80 to 120 km/h (49.71 - 74.56 mph) in fourth gear. Behind these figures there is a fascinating driving experience, marked by the sonorous sound of the new mechanically supercharged V6 engine, its mighty propulsive power, its free-revving character and its sharp, spontaneous response to the throttle.

The 3.0 TFSI is the new range-topping unit in Audi's V6 engine family. It develops 245 kW (333 hp) and delivers a powerful 440 Nm of torque (324.53 lb-ft) to the crankshaft between 2,900 and 5,300 rpm. The 3.0 TFSI combines two state-of-the-art technologies - gasoline direct injection and mechanical supercharging. These technologies make it a prime example of Audi's downsizing philosophy for greater efficiency, i.e. engine capacity is replaced by a supercharger.

Audi delivers the Audi S4 and S4 Avant with a six-speed manual transmission as standard - its short and precise lever travel and low operating force make every gear change a delight. Special selector fork mountings decouple the gear lever from the driveline so that the driver does not sense any vibration.

Internal friction in the transmission has been minimized, improving the already high level of efficiency still further. A change-up display in the driver information system helps the driver to adopt a more economical driving style. It shows which gear is in use and recommends a different gear if this would be a better choice. The dual-mass flywheel and the hydraulically actuated single dry-plate clutch are not bolted to the crankshaft in the usual way, but supported on the transmission input shaft. On the Audi S4 and S4 Avant, the differential is located in front of the clutch. Output to it is via a hollow shaft, which features a so-called beveloid gear on both sides, enabling it to be installed at an inclined angle of 7.2 degrees.

Interchanging the components has moved the front axle forward by 154 millimeters (6.06 in) compared with the previous model. This has many advantages - a long wheelbase, a short front overhang and good weight distribution. It results in handling characteristics that set new standards in terms of dynamism, precision and stability.

The very design of the front section alludes to the power of the new Audi S4 and S4 Avant. The LED daytime driving lights in the standard-specification xenon plus headlights can be seen from afar. The single-frame grille, in platinum gray, has the typical look of the S models from Audi - its vertical double struts bear chromed inserts and the S4 badge. Two ribs define the lower trapezoidal air vents and chrome rings encase the front fog lights. An aluminum-look "blade" forms the centerpiece of the striking bumper.

The side view also reflects the athletic character of the Audi S4 and S4 Avant. Sill trims painted in the body color emphasize the width of the body; the aluminum-look exterior mirror housings gleam. The new midsize athletes have a powerful stance on the road with their 18 or 19-inch wheels, the rim spokes allow the blackpainted brake calipers to shine through. The so-called high-gloss package adds elegant touches all round the side windows with aluminum strips and black trims.

At the rear, too, the new Audi S4 and S4 Avant remain unmistakable - thanks to the badge on the trunk lid, the LED lights and the quadruple oval tailpipes. The rear bumper, incorporating a diffuser, has also been redesigned, its blade likewise in aluminum look. The spoiler - on the trunk lid of the sedan and the roof edge of the Avant - separates the airflow in a clean, defined way, further enhancing driving stability at high speeds.

Dynamic, elegant, sophisticated - this is the interior of the new Audi S4 and S4 Avant. The ergonomics are exemplary, the amount of space generous; the electromechanical parking brakes leaves room on the centre tunnel. The interior in cool black - the roof lining is optionally available in silver - creates an atmosphere of sporty and technical expertise, underlined by the uncompromising craftsmanship so typical of Audi.

The many meticulously thought-out details are another characteristic of the brand. The S4 logos are found on the door sill trims, the leather multifunction sports steering wheel, the remote control key and on the instruments, the dials of which are gray, the needles white. Understated aluminum-look inlays provide subtle highlights; the versions with seven-speed S tronic sport aluminum-look shift paddles, mounted behind the steering wheel.
