Audi S5: B8 and B9 generations, engines, and body types
The Audi S5 is the sporty version of the A5 with a powerful V8 or V6 engine and quattro all-wheel drive. We look at the two most popular used market generations, their engines, body types, and what to check before buying a used S5.
S5 in brief
The S5 debuted in 2007 as the sporty coupe version of the A5. Later, Cabriolet and four-door Sportback body styles were added, making the S5 more versatile. All versions come with quattro all-wheel drive and a sporty suspension.
This is the car for those who need excellent dynamics but don't want to sacrifice daily comfort and a high-quality interior.
Which generation to choose
The B8 generation (2007–2016) initially had a naturally aspirated 4.2-litre V8, later replaced by a supercharged 3.0-litre V6. It's appreciated for its classic character and is often more affordable, but the cars are quite old, so condition is more important than features.
The B9 generation (from 2016) uses a more modern platform, a lighter body, a new 3.0-litre V6 with a turbocharger, and more advanced multimedia. It's pricier, but technically more advanced and economical.
Engines and transmissions
The B8 initially used a 4.2-litre V8 (around 354 hp), later replaced by a 3.0-litre supercharged V6 (around 333 hp). Most commonly, a 6-speed manual or 7-speed S tronic transmission was used, with the V8 versions also having an automatic tiptronic transmission.
The B9 has a 3.0-litre V6 with a turbocharger (around 354 hp) and an 8-speed tiptronic transmission. In Europe, an S5 TDI with around 347 hp and a mild hybrid was also available.
What to check when buying a used S5
When buying a B8, check the cooling system for leaks. Direct-injection engines are prone to deposits in the intake valves, so proper maintenance and high-quality oil are crucial.
Test the S tronic and tiptronic gearboxes by driving slowly and quickly: shifts should be smooth, without hesitation. Ask if the gearbox oil has been changed according to the manufacturer's schedule.
In the Cabriolet version, inspect the roof mechanism, seals, and electrical operation. For all S5s, check the brakes, tyres, and suspension, as sporty versions wear out faster.
