New Audi RS4 Avant V6 Biturbo in SUPERDETAIL with 2.9 TFSI twin-turbo V6 [4K]

“Combining consistent sportiness with unlimited everyday usability may seem like an unconventional idea to some, but to us, the high-performance Avant is one of the best concepts of our 25-year history,” says Oliver Hoffmann, Managing Director of Audi Sport GmbH. “As our long-standing bestseller, the Audi RS 4 Avant contributes significantly to the success of Audi Sport GmbH.”

Muscular: the exterior design

The front section of the new RS 4 Avant was completely redesigned. The RS 4 Avant differs considerably from the A4 Avant. The Singleframe is wider and flatter as compared to the base model. Just like its big RS brothers, the RS 6 Avant and the RS 7 Sportback, the RS 4 Avant also features the three-dimensional honeycomb structure in gloss black that is typical for the RS model series. To give it a clean look, the Singleframe is designed without a frame. The new eggcrate grille with the RS 4 emblem is inserted directly into the bumper with the large lateral air inlets and vertical flaps.

The shape of the LED headlights of the RS 4 Avant has also been redesigned. The optional matrix LED headlights with darkened bezels complete the revised appearance of the high-performance Avant and differentiate it within the A4 family. The wheel arches with the quattro blisters located above are each 30 millimeters (1.2 in) wider at the front and back as compared to the Audi A4 Avant. Gloss black design elements positioned right next to the headlights underline the effect of width of the new RS 4 Avant.

The gloss black, matt aluminum and carbon styling packages add individual accents to the inlay in the sill, the exterior mirror housings and the front and rear bumpers. Upon request, the gloss black and carbon styling packages also include the Audi rings and the RS logo in black on the front and rear. The RS badges can be omitted completely for a more understated look. The roof rails are designed in matt black as standard. The RS-specific roof edge spoiler and the diffuser insert as well as the chrome tailpipes of the RS exhaust system give the vehicle a distinct finish. The optional RS sport exhaust system with black tailpipe trims creates a particularly sporty sound experience. The driver can decide whether they want a sporty or subdued sound via the Audi drive select dynamic handling system.

Full tractive power: the drive

With the 2.9 TFSI twin-turbo V6, Audi Sport GmbH is building on the legendary 2.7 liter V6 of the first RS 4 Avant from 1999. Back then, the twin-turbo V6 had a power output of 380 HP.
The new RS 4 Avant now outputs 450 metric HP, which equals an output of 155.5 metric hp per liter. This allows the RS 4 Avant to accelerate from zero to 100 km/h (62.1 mph) in just 4.1 seconds. The TFSI engine weighs just 182 kilograms (401.2 lb), which is 31 kilograms (68.3 lb) less than the V8 engine in the predecessor model from 2012. This benefits the gross weight and the axle load distribution—two prerequisites for the impressive performance. The twin-turbo V6 applies an impressive 600 Nm (442.5 lb-ft) of torque to the crankshaft in a broad engine speed range from 1,900 to 5,000 rpm. The RS dynamic package increases the electronically governed top speed from 250 to 280 km/h (155.3 to 174.0 mph).

The two turbochargers of the 2.9 TFSI are each assigned to a cylinder bank and build up a boost pressure of up to 1.5 bar. Like with all V6 and V8 engines from Audi, the turbochargers are installed within the 90-degree interior “V” of the cylinder banks, and thus the exhaust side of the cylinder heads is on the inside, while the intake side is on the outside of the engine. This layout enables compact construction and short gas flow paths with minimal flow losses, allowing the 2.9 TFSI to respond particularly spontaneously to movement of the accelerator pedal.
