New Audi RS6 Avant and RS7 Sportback 2020 pricing and specs detailed: Mercedes-AMG E63 rivals go hybrid

Audi Australia has confirmed pricing and full specification for the new-generation RS6 Avant wagon and RS7 Sportback liftback ahead of their combined launch on July 24.

The RS6 Avant is priced from $216,000 plus on-road costs, while the RS7 Sportback charges $224,000, making them a massive $32,355 and $37,140 cheaper than their predecessors.

Both models are motivated by a 4.0-litre twin-turbo V8 petrol engine that pumps out 441kW of power from 6000-6250rpm and 800Nm of torque from 2050-4500rpm despite coming armed with cylinder deactivation.

This unit is mated to an eight-speed torque-converter automatic transmission and a rear-biased version of Audi’s signature quattro all-wheel-drive system, as well as a 48V mild-hybrid set-up that has coasting and extended stop-start functionality.

The combination helps the RS6 Avant and RS7 Sportback sprint from a standstill to 100km/h in just 3.6 seconds while on the way to 200km/h in 12.0s and their electronically limited top speed of 280km/h.

Standard equipment in the pair otherwise includes adaptive air suspension, rear-wheel steering, a sports exhaust system, a rear limited-slip differential, metallic or pearl-effect paintwork, HD Matrix LED headlights, 22-inch alloy wheels, power-folding side mirrors with heating, soft-close doors, rear privacy glass, a power-operated tailgate and black exterior trim.

Inside, 10.1-inch and 8.6-inch touchscreens, satellite navigation, Android Auto and wireless Apple CarPlay support, digital radio, a 705W Bang & Olufsen sound system with 16 speakers, a 12.3-inch digital instrument cluster, a panoramic sunroof, keyless entry and start, a wireless smartphone charger, power-adjustable front sports seats with heating, a power-adjustable steering column and Valcona and Nappa leather upholstery feature.

Advanced driver-assist systems extend to autonomous emergency braking, lane-keep and steering assist, adaptive cruise control with stop and go functionality, tyre pressure monitoring and surround-view cameras, among others.

Options for the Mercedes-AMG E 63 rivals include a carbon-ceramic brakes package that replaces the standard 420mm steel discs with 440mm rotors. Either way, the rear discs measure 370mm in diameter, while the front rotors are paired with 10-piston callipers.
