The world has been without an Audi RS5 since 2015, but finally, that changes. Today at the Geneva Motor Show, the 2018 RS5 made its debut with 450 horsepower and all sorts of clever chassis tricks up its sleeve. It's the all-wheel drive alternative to the M4.
That 450 horsepower comes from a new 2.9-liter twin-turbo V6 that Audi says has been "developed from the ground up." The engine is based off the V6 that made its debut in the new Porsche Panamera 4S and generates 442.5 lb-ft of torque in this application. As with the new Audi S5, the only transmission option for the RS5 is an eight-speed Tiptronic automatic.
This drivetrain helps the RS5 sprint from 0-60 mph in 3.9 seconds, and when ordered with the optional Dynamic Package, top speed is 174 mph. The RS5's weight of 3648 lbs is 132 lbs lighter than its predecessor, and Audi says it's capable of achieving 27 US mpg in the European test cycle.
The RS5's 450 horsepower is sent to all four wheels with a torque split of 40 percent at the front axle, and 60 percent at the rear . Optional is a rear sport differential, which should help make the RS5 even more nimble. Also, as the top picture shows, it'll allow for oversteer. There's five-link suspension at both the front and the rear, and there's an optional RS sport suspension with adaptive dampers. Carbon ceramic brakes and dynamic steering are also available as options.
Inside, there's all the goodness you'd expect from a modern Audi, a handful of trim pieces to remind you you're in an RS5. Outside, Audi says the design is inspired by the Audi 90 IMSA GTO that dominated US sports car racing back in the early 1990s.
As the only all-wheel-drive car in its segment, the RS5 should make for an interesting comparison with the M4, Mercedes-AMG C63, and Cadillac ATS-V. Hopefully we'll find out how it drives sooner than later.
