Under the 2018 S4's hood is a 3.0-liter turbo-six that produces 354 hp and 369 lb-ft. Unlike my long-term A4, the S4 gets a conventional eight-speed automatic, and its all-wheel-drive system is biased 40/60 front/rear.How does the 2018 Audi S4 compare to its competitors?
The 2018 Audi S4 's upgrades go deeper than just a powerful six-cylinder engine, and we tested the more performance-focused sedan to see how it compares to rivals from BMW, Mercedes-Benz, Infiniti and, well, Audi in the form of our long-term A4.Is the Audi S4 AWD or AWD?
All 2018 S4s use Audi’s fantastic Quattro all-wheel-drive (AWD) system. An 8-speed automatic is your only transmission, but it’s a good one; smooth all the way. Like so many other new cars seeking to eke out better fuel economy, the Audi S4 uses an engine start/stop system that cuts power at idle.
