Bold face. Clearly identifiable as both a current Ford and a Mustang. Sculpted hood suggests power. After a few iterations, Audi's "singleframe" grille works. RS 5 has flared fenders.
Muscular body sides. The wheels are a good match. Far cleaner than the somewhat cartoonish Mustang exterior, yet also muscular, in its own way.
Does the upper body appear disproportionately small? It's not easy to achieve such excellent proportions with a front-drive architecture.
Rear panel maintains a stylistic connection with past Mustangs. Interplay between character line and fender flares. Subtle waves ripple through RS 5's body sides.
The interior also effectively combines current Ford design with traditional Mustang flavor. Little distinguishes the RS 5's interior from the far less pricey A5's. Still nicer than the Ford
The fake stitching needs to go. And the chrome trim needs to be more convincing, if not real metal. More American than the exterior. You're clearly not in an Audi.
Plenty of buttons, mostly logical. Toggles at the base of the center stack select drive modes. Cushier than the Audi's driver seat. Good lateral support.
The optional Recaro driver seat provides outstanding lateral support, but at a price. And a cost. The Mustang's back seat is even less adult-friendly than the Audi's.
This isn't a tiny roadster. Plenty of space for two people's luggage. The big bulging hood isn't deceptive. Massive cover makes the large engine appear even larger.
The best-looking part of the Mustang is under the hood. Even under the engine cover. DOHC heads on a large engine are large.
