With its 605 hp, the Audi RS6 Avant and RS7 Sportback performance were not exactly amorphous. The 605 bhp new version of their performance now make the station wagon and coupe the most powerful four-door market. Competition in the German premium cars is eternal, and Audi had taken a little late in some segments
Increased performance and outstanding efficiency - the new Audi RS6 Avant performance and the new Audi RS7 Sportback performance top their respective model lines. Their 4.0 TFSI engine with 445 kW (605 hp) and up to 750 Nm (553.2 lb ft) of torque push acceleration nearly to levels usually reserved for supercars. Fuel consumption remains unchanged at 9.6 and 9.5 liters per 100 kilometers (24.5 and 24.8 US mpg), respectively, corresponding to 223 and 221 g CO2 per km (358.9 and 355.7 g/mi). These are best-in-segment figures.
Engine
The new RS performance models are equipped with the most powerful version of the free-revving V8 biturbo power unit with a displacement of 3,993 cc. Power output has been increased by 33 kW (45 hp) to 445 kW (605 hp), which is available between 6,100 and 6,800 rpm. The maximum rpm has thus also been increased by 200 revs. A constant 700 Nm (516.3 lb-ft) of torque is available between 1,750 and 6,000 rpm. A particular highlight of the engine is an overboost function allowing the driver to temporarily draw on up to 750 Nm (553.2 lb-ft) between 2,500 and 5,500 rpm. Overboost is activated automatically under full load if the engine/transmission setting is set to "dynamic" mode. The boost pressure indicator in the RS menu turns red when overboost is active.
The high-tech character of the 4.0 TFSI is manifested in numerous details, such as the twin-scroll turbochargers that provide for the early and rapid development of torque, the innovative thermal management and the layout of the cylinder heads. Their intake side is on the outside and the exhaust side on the inside. The turbos and their intercooler are located in the inner V. This layout results in short gas flow paths with minimal flow losses and spontaneous response.
The road performance of the new RS6 Avant performance and the new RS7 Sportback performance speaks for itself: The two RS high-performance models sprint like supercars from 0 to 100 km/h (62.1 mph) in just 3.7 seconds, an improvement of 0.2 seconds over the respective base RS model.
They need just 12.1 seconds to accelerate from 0 to 200 km/h (124.3 mph), 1.4 seconds less than the base RS models. Audi limits the top speed in the standard configuration to 250 km/h (155.3 mph). Top speed can be increased to 280 km/h (174.0 mph) upon request, and 305 km/h (189.5 mph) is possible with the dynamic package. In the ECE cycle, the 4.0 TFSI still consumes just 9.6 and 9.5 liters of fuel per 100 kilometers (24.5 and 24.8 US mpg), respectively, corresponding to 223 and 221 g CO2 per kilometer (358.9 and 355.7 g/mi).
These top figures for power and efficiency are made possible by the technological expertise of Audi and quattro GmbH. Engineering skills and long years of experience with RS high-performance models enabled further optimization of the 4.0 TFSI, from the specific engine management system with increased rpm and boost pressure to the Audi cylinder on demand (COD) system. At low to moderate load and engine speed, this deactivates cylinders two, three, five and eight by closing their valves and shutting off fuel injection. The high-performance power unit then runs as a four-cylinder engine until the driver presses firmly down on the gas pedal again. The only thing the driver notices is significantly reduced fuel consumption.
These two monsters, which differ only in their inner rims 21 "specific, Quattro logo on the lower grille and a matte titanium fittings (not to mention a unique Ascari Blue paint option), will arrive in dealership in January. At 133,700 euros for the RS 6 Performance and 142,900 euros for the 7 RS Performance, this represents an additional cost of about 10,000 euros in both cases.
