2023 Audi S4 Sedan Performance

All versions of the S4 feature the same engine with the same output. The Audi S4 has a turbo strapped to a 3.0-liter V6 and produces 349 hp and 369 lb-ft of torque, all of which is harnessed with the aid of a quattro all-wheel-drive system and an eight-speed Tiptronic automatic transmission - no manual is available, and Audi doesn't have a switchable AWD system like its rivals. Still, it's an impressive machine, with the Audi S4's performance promising 0-60 mph times of 4.4 seconds and a top speed of 155 mph. These figures are pretty good, and the Audi S4 sedan will return them time and time again. However, most Audi S4 reviews will concede that the car seems a little docile and a little unassuming. For impressive performance in the suit of a sleeper, the S4 is good, but it certainly won't set your hair on fire the way a Giulia can.

The S4 is fitted with a turbocharged 3.0-liter TFSI engine with 349 hp and 369 lb-ft of torque across all trim levels. All models also feature an eight-speed Tiptronic automatic transmission, and it's very, very good - but it's not quite the greatest. Sure, it changes up quickly and smoothly, with little hesitation, but it's that hint of hesitation that keeps it from being among the absolute best. Still, it's not offensive at all, and you'll find that it can be left to its own devices without frustrating you. Switch to manual mode, and it's more engaging, with sharp changes and an almost indiscernible pause between shifts. The engine is good too, but the quiet cabin of the S4 further muffles the characterless motor, especially if you opt for the top trim as it comes with dual-pane acoustic glass for the front windows. At least the engine is a strong one, with minimal turbo lag and quick responses to the inputs of your right foot. That said, it lacks the excitement of the old B5 with its twin-turbo 2.7 V6 or the addictive grumble of the RS4's V8.

Gas mileage figures for the S4 have been estimated by the EPA as 21/30/24 mpg on the city/highway/combined cycles. With a 15.3-gallon gas tank, that will mean you should achieve around 367 miles of range with mixed driving. The Merc C43 has a bigger tank but won't get any farther because it achieves worse figures of 18/27/21 mpg.
