Sitting beneath the hood of the new RS7 Sportback is Audi’s familiar 4.0-liter twin-turbo V8 engine supplemented with the same 48-volt main on-board electrical system as the RS6 Avant. The car delivers a total of 592 hp and 590 lb-ft (800 Nm) of torque and can hit 62 mph (100 km/h) in a head-snapping 3.6 seconds before topping out at an electronically-limited top speed of 155 mph (250 km/h).
Should customers want a little extra speed, they can opt for the Dynamic package that lifts the vmax up to 174 mph (280 km/h) or the Dynamic plus package that lifts it up to 189 mph (305 km/h).
It has a 48-volt system and cylinder deactivation too
Audi says that the 48-volt system can recover up to 12 kW of power under gentle acceleration and feed it into the lithium-ion battery. Whenever the driver is sitting at a speed between 34 mph (55 km/h) and 99 mph (160 km/h), the powertrain will either start recovering energy or coast with the engine switched off. The moment the driver steps on the throttle, the belt alternator start switches on the twin-turbo V8.
Adding to the efficiency of the new RS7 Sportback’s powertrain is a cylinder on demand system that will deactivate cylinders 2, 3, 5, and 8 in higher gears at low to medium loads and engine speeds. As mentioned, the car uses an eight-speed transmission and permanent all-wheel drive system that splits power 40:60 front-to-rear in most situations but can send up to 70 per cent of power to the front wheels and up to 85 per cent of power to the rear wheels.
The Audi RS7 Sportback comes as standard with adaptive air suspension that includes automatic level control and can be set to three different modes. In normal mode, the air suspension means the RS7 Sportback sits 20 mm (0.8-inches) lower than an A7 Sportback on traditional suspension while at speeds above 74.6 mph (120 km/h), the ride height drops by an additional 10 mm (0.4-inches). A lift mode is also available to bump up the ride height by 20 mm (0.8-inches).
To enhance the road-holding abilities of the car, customers can select the dynamic all-wheel steering system while also having the configurable Audi drive select dynamic handling system at their disposal. In terms of braking, the RS7 Sportback features huge 420 mm (16.5-inch) discs at the front and 370 mm (14.6-inch) discs at the rear. There are also ceramic brakes available that increase the size of the front discs to 440 mm (17.3-inches).
Inside, the RS7 Sportback is much the same as other models in the A7 family but does include a fully perforated RS sport leather steering wheel with aluminium shift paddles and RS-specific displays in the Audi virtual cockpit instrument display. Audi has also developed RS sports seats and added various RS7 badges to spruce up the cabin.
Audi has yet to release pricing for the 2020 RS7 Sportback but says it will start arriving at dealerships across Europe by the end of 2019.
