2020 AUDI RS7 – Specs, Design, Test Drive — автоновости

The V8 4.0 TFSI in the new 2020 Audi RS 7 Sportback produces 600 horsepower (441 kW) and delivers 590 lb-ft (800 Nm) of torque within a broad range from 2,050 to 4,500 rpm. The high-performance Sportback will sprint from 0 to 100 km/h (0 to 62 mph) in only 3.6 seconds. The top speed is electronically limited to 250 km/h (155 mph); this can be increased to 280 km/h (174 mph) with the Dynamic package and to 305 km/h (189 mph) with the Dynamic plus package.

Thanks to its mild hybrid system (MHEV) with a 48-volt main on-board electrical system, the 4.0 TFSI combines maximum performance with high efficiency. The belt alternator starter can recover up to 12 kW power under gentle acceleration and feed it into a lithium-ion battery as electricity. If the driver releases the accelerator at a speed between 55 and 160 km/h (34.2 to 99.4 mph), the drive management will select one of two options. Depending on the driving situation and the settings in Audi drive select, the new RS 7 Sportback will either recover energy or coast with the engine switched off. When the driver steps on the accelerator, the belt alternator starter will start the engine again. MHEV technology allows for start-stop mode at speeds below 22 km/h (13.7 mph). As soon as the vehicle in front of the new RS 7 Sportback starts moving, the engine will spring back to life—even if the brakes are applied. With the MHEV-technology it is possible to reduce fuel consumption by as much as 0.8 liters per 100 kilometers.

The cylinder on demand (COD) system is another weapon in the vehicle’s armory when it comes to efficiency. In higher gears at low to medium loads and engine speeds, it will deactivate cylinders 2, 3, 5, and 8 by halting injection and ignition and closing the intake and exhaust valves. In four-cylinder mode, the operating points will switch to the active cylinders at higher loads, thereby improving efficiency, while the deactivated cylinders continue to run like gas springs, largely without any losses. When the driver presses the accelerator pedal, they are reactivated immediately. Each switchover takes mere milliseconds and is virtually undetectable by the driver and passengers.
