A further efficiency component of the 2.9 TFSI is the thermal management system. The crankcase and the cylinder head have separate coolant circuits. After a cold start, the switchable water pump controls the flow of coolant through the engine so that the oil is warmed up as quickly as possible. The exhaust manifolds are integrated in the cylinder head, and coolant circulates around them which helps ensure rapid warming up. When the engine is warm, this technology lowers the exhaust temperatures - consumption drops drastically, especially when driving in a sporty way. The great efficiency of the V6 bi-turbo is also partly to do with low friction. For example, the fully adjustable oil pump only builds up as much pressure as necessary.
The 2.9 TFSI V6 bi-turbo engine, which Audi developed from the ground up, offers sharp increases in power and efficiency as well as an incomparably full-bodied RS sound. It delivers 331 kW (450 hp). And it‘s peak torque of 600 Nm (442.5 lb-ft) - 170 Nm (125.4 lb-ft) more than the previous model - is available across a broad engine speed range from 1,900 to 5,000 rpm. The top model in the A5 family sprints from 0 to 100 km/h (62.1 mph) in 3.9 seconds, and reaches a top speed of 250 km/h (155.3 mph) - with the optional RS dynamic package it can even reach 280 km/h (174.0 mph).
The front of the Audi RS5 Coupe looks sportily aggressive thanks to massive air inlets and RS bumpers with a blade in contrasting color. The broad Singleframe with high-sheen black honeycomb grille and quattro lettering highlights an aluminum-look frame. A sharply drawn shoulder line in the form of the characteristic wave lends the new.
