Unlike other websites and magazines, our ratings are not based solely on a singular road test, but rather a more encompassing batch of criteria: quality, safety, comfort, performance, fuel economy, reliability history and value. When comparing vehicles using our Rating System, it's important to note that the rating earned by each vehicle correlates only to the models within its class. For example, a compact car cannot be compared to a SUV—They are different vehicles altogether.
You can interpret our ratings in the following way:
5-Star: Outstanding vehicle. Only the most exceptional vehicles achieve this rating.
4-Star: Very Good vehicle. Very good and close to being the best vehicle in its class.
3-Star: Good vehicle. Decent, but not quite the best. Often affordable, but lacking key features found in vehicles of the same class.
2-Star: Below average vehicle. Not recommended, and lacking attributes a car buyer would come to expect for the price.
1-Star: Poor vehicle. Simply does not deserve to be on the road.
2018 Audi S5 OVERVIEW
Like other German premium automakers, Audi boasts a group of stand-apart, high-performance variants of its standard models, identified by the “S” prefix. Based upon the stylishly sporty, but civilized, A5 coupe and convertible, the S5 versions might be considered the youthfully impetuous outsiders in Audi's family of respectable compact models. Packed with performance upgrades, each S5 boasts sufficient power and sport-performance technology to behave downright aggressively, even if they appear to be upstanding automotive citizens.
What's New for 2018
Audi has redesigned the S5 – along with its A5 parent – for a second generation, adding a new Sportback body style. Billed as a “five-door coupe,” the Sportback joins the two-door S5 coupe and convertible. A new version of Audi’s 3.0-liter V6 develops 354 horsepower. An eight-speed automatic transmission has replaced the previous six-speed unit.
Choosing Your Audi S5
Although the S5 shares its basic body with the more common A5, it looks a bit more aggressive, due to a lowered suspension, subtly revised trim, and unique 18-inch wheels. Of course, the vital difference lies beneath the hood of each S5, where a new turbocharged 3.0-liter V6 whips up 354 horsepower and 369 pound-feet of torque. The energetic V6 mates with a new eight-speed automatic transmission. A manual gearbox is not available.
Every S5 has Audi’s Quattro all-wheel drive. There are four distinct driving modes: Comfort, Auto, Dynamic, and Individual. The flat-bottom steering wheel includes shift paddles. Five-double-spoke 18-inch wheels hold summer performance tires.
Acceleration to 60 miles per hour takes a mere 4.4 seconds, according to Audi. Fuel economy of the coupe and Sportback are estimated at 21 miles per gallon city, 30 highway, 24 combined, according to the EPA. The convertible is a hair less thrifty, at 20/29/23 mpg.
Expect to pay a premium of $7,700 for the soft-top convertible, compared to the coupe.
As before, S5 models are available in two trim levels:
Clearly, the new Sportback appeals mainly to drivers who make frequent use of the back seat, which isn’t exactly roomy in a coupe or convertible. Upgrading to the Prestige adds some tempting technology (mostly optional for Premium Plus), as well as the possibility of getting the additional features in the Driver Assistance package.
