The newly developed 2.9-liter TFSI engine in the Audi RS 4 Avant delivers a completely new dimension of torque and efficiency. From 1,900 to 5,000 rpm, the V6 twin turbo sends a huge 600 Nm of torque to the crankshaft – 170 Nm more than in the previous model. With its output of 331 kW (450 hp), equating to a performance of 155.5 hp per liter, the RS 4 Avant accelerates from zero to 100 km/h in 4.1 seconds, which is 0.6 tenths faster than before. The RS dynamics package increases the electronically controlled top speed from 250 to 280 km/h. In the new European driving cycle, the vehicle uses just 8.8 liters of fuel per 100 kilometers, equivalent to 200–199 grams of CO2 per kilometer. These values represent a 17% reduction in fuel consumption compared with the previous model.
In using the 2.9-liter TFSI V6 twin turbo, Audi Sport is following up on the legendary first-generation RS 4 Avant. The RS 4 released back in 1999 was also equipped with a V6 twin turbo – the first ever highly supercharged twin turbo engine from Audi. Delivering an output of 280 kW (380 hp), the engine performs at 141 hp per liter. The first RS 4 Avant went from zero to 100 km/h in 4.9 seconds. Huge demand for this founding vehicle of the V6 twin turbo success story led Audi to double the original number of models planned for production. In total, the brand produced 6,030 units of the first-generation RS 4.
