2021 Audi S5 MODEL OVERVIEW

Pros

  • Sleek exterior styling
  • Good cargo space in the Sportback model
  • Superb materials and quality

Cons

  • Driving experience lacks feel
  • Standard A5 is plenty quick
  • Adaptive cruise control isn't standard

Some cars make you choose between style and performance, but not the S5. Mechanically it's basically an S4, but sleek sheetmetal sets it apart—coupe, cabriolet, and four-door Sportback models are available, and all look fantastic. Turbo V-6 power and Quattro AWD provide the S5's sporty credentials. The current second-generation S5 debuted for 2017, and received a refresh for 2020.

What's New

  • All trims now equipped with lane-departure warning and wireless Apple CarPlay
  • The Premium Plus trim gains adaptive cruise control and lane-keep assist
  • Sportback Prestige models now include heated rear seats

What We Think

Sometimes, specs don't really matter. If they always did, Audi wouldn't bother building the S5 alongside the S4—hardware and equipment are basically identical between the two cars. So what does the S5 have that the S4 doesn't?

Perhaps most obviously, style. The S4 looks good, but the S5's sleek bodywork gives it head-turning presence. That's an intrinsic feature of many coupes, and folding the roof down on the cabriolet makes the S5 even more rakish. Somehow, though, the four-door Sportback hatch model might be the best-looking of the bunch.

The S5 Sportback doesn't only have a stylistic advantage over the S4. It's more practical, too, thanks to its surprisingly deep and spacious hatchback cargo area.

In terms of features and specs, though, the S5 and S4 are very similar. Both are high-tech and present Audi's impeccable build quality. Performance is nearly identical, with plenty of acceleration but not much in the way of feel. So why is the S5 so appealing? Just look at it.

Performance and Fuel Economy

All S5 models pack a turbocharged 3.0-liter V-6 producing 349 hp and 369 lb-ft of torque. That engine is joined to an eight-speed automatic transmission and a sport-tuned version of Audi's Quattro AWD system. In MotorTrend testing of the slightly more powerful (354-hp) 2018 S5 Sportback, 0-60 mph acceleration took between 4.3 and 4.5 seconds. EPA-rated fuel economy is 20/28 mpg city/highway for the coupe and Sportback models, 20/26 mpg for the Cabriolet.

How Quick Is the RS 5?

If the S5 simply isn't sporty enough, Audi builds the RS 5. Its twin-turbocharged 2.9-liter V-6 makes 444 hp and 443 lb-ft of torque, good for a 0-60 mph time of under 4.0 seconds. Bigger brakes, stiffer suspension, louder exhaust, and a different tune for the Quattro AWD system give the RS 5 higher performance than the S5, but we found it more restrained than some direct competitors. Regardless, whether in coupe or Sportback form, the RS 5 looks the part with its more aggressive body styling.

Safety

Although the S5 has not been safety tested, its performance should be similar to the standard A5. From the NHTSA, the A5 Sportback gets a five-star overall safety rating, the highest possible score. From the IIHS, the A5 coupe earns the top Good score in five crashworthiness tests, while the A5 Sportback earns an additional Good rating in the passenger-side small front overlap test.

Front automatic emergency braking and lane-departure warning are equipped on all S5 trims as standard. Adaptive cruise control, lane-keep assist, road sign recognition, and rear and side cross-traffic alerts are included on the Premium Plus and Prestige trims.

Cargo Space and Interior Room

In the S5 Sportback, cargo space is 21.8 cubic feet behind the second-row seats, or 35.0 cubic feet with those seats folded down. Trunk capacity measures 10.9 cubic feet in the S5 coupe. It's just 7.3 cubic feet in the S5 cabriolet.

Front-row legroom measures 41.3 inches in all S5 models. Front-row headroom is 39.4 inches in the Sportback, 37.4 inches in the coupe, and 40.0 inches in the cabriolet. Second-row legroom is 35.1 inches in the Sportback, 32.7 inches in the coupe, and 33.3 inches in the cabriolet. Second-row headroom is 37.0 inches in the Sportback, 36.1 inches in the coupe, and 36.3 inches in the cabriolet.

Technology

The S5 is equipped with a 10.1-inch infotainment touchscreen. Wireless Apple CarPlay, Android Auto, Bluetooth streaming, and two front-row USB ports are included; a wireless charging pad is added on the Premium Plus trim. The Premium trim has a 7.0-inch gauge cluster display, while the Premium Plus and Prestige trims have a 12.3-inch all-digital gauge display. Prestige models also get built-in navigation and a head-up display. The standard sound system has 10 speakers, and a 19-speaker Bang & Olufsen premium setup is also available.
