Our spy photographers have caught the upcoming Audi RS 7 testing in the snow and flaunting its shapely silhouette. The high-performance variant of Audi 's swoopy fastback sedan is scheduled to debut sometime next year and will eventually do battle with the Mercedes -AMG GT 4-Door Coupe, Porsche Panamera , and BMW M5 . Some of the dead giveaways that this is the RS 7 are the large oval exhaust tips, which distinguish Audi's RS models from lesser variants. Behind all of the camouflage, the fenders look wider than on the standard A7 . This particular prototype also appears to have a different lower front fascia with larger side openings for improved air flow to cool the brakes. It's also sporting sizable front brakes and larger-diameter alloy wheels. The car also appears lower than a standard A7, which could hint at a height-adjustable air suspension or possibly a lowered fixed setup. As with past Audi RS models, it's the small details that will set this car apart from its more pedestrian sibling, which should help the RS 7 to be one heck of a sleeper. Our spy photographers tell us that the RS 7 will debut with a new twin-turbo V-8 good for 650 hp. That powertrain is likely to be shared with the eight-cylinder version of the Bentley Continental GT . Look for the 2020 Audi RS 7 to debut next year, possibly at the Geneva motor show.
