Following the reveal of the Audi S6 and S7 TDI models, the diesel-powered versions of Audi’s famous performance machines, the four-ringed brand suffered some backlash among enthusiasts. Audi’s fast diesel engines are great but they don’t belong in proper ‘S’ model cars like the S6 and S7. Thankfully, those diesel engines are only set for the European market and the North American market will be getting proper engines. We learned this from the American-bound S6 that was recently revealed. Now, we get to see the American-spec Audi S7 and it gets the same engine.
Powering the ‘Merican Audi S7 is the same 2.9 liter twin-turbocharged V6 that powers the new S6. While it’s technically the same engine as the Audi RS5, it gets a unique twist in the S6 and S7 in that it also gets a 48-volt electrical system with an EPC (Electrically-Powered Compressor). That EPC acts as a third turbocharger, just one powered by electricity rather than exhaust gases, and it helps to eliminate turbo-lag and provide sharper response at low revs. It’s a very small compressor so it doesn’t add any extra power over the RS5’s engine but it does increase the engine’s response.
That twin-turbo V6 makes 444 hp and 443 lb-ft of torque, all of which helps get the Audi S7 from 0-60 mph in 4.5 seconds. That’s very quick but it’s actually a bit behind some of its competitors. For instance, the BMW M850i Gran Coupe uses a 4.4 liter twin-turbocharged V8 with 523 hp and gets to 60 mph in 3.8 seconds. Just like the S6, the Audi S7 will use an eight-speed ZF-sourced automatic gearbox to send its power to all four wheels.
The S7 comes as-standard with S-tuned adaptive air suspension, upgraded brakes and an available S sports package brings all-wheel steering and a limited-slip rear differential.
Where the Audi S7 really makes a case for itself is with its body style. That sleek, sexy shape isn’t just more stylish than its competitors, and its S6-sibling, it’s also more practical. So its smooth roofline actually opens up into a liftback tailgate, giving the Audi S7 more cargo space than the S6 and BMW M850i. So it’s better looking than both while also being more practical.
Style isn’t cheap, though. If you want the sleek, sexy S7, you’ll have to pay a premium. Starting price for the S7 in the ‘States is $83,900 for the ‘Premium Plus’ model and the more luxurious ‘Prestige’ trim comes in at $89,500. So it’s almost $20,000 more than its rival from Bavaria while being less powerful and slower. So if you want the new S7’s beauty and practicality, you’re going to have to pay. I don’t think you’ll be upset with your purchase, though.
