The S5 is the top performance spec model in the A5 range, barring the very top spec RS5 that will be made in limited numbers. The new Audi S5 2018 model has felt the pressure that has been on all car manufacturers to make their motors cleaner, more fuel efficient, and produce less CO2, so Audi took the step when the Sportback and convertible S5 variants were released of downsizing from a normally aspirated 4 litre V8, to a newer 3.0 litre supercharged engine, which has a horsepower level of 333 bhp, however due to the supercharger it has a higher level of torque than the older V8, meaning mid-range acceleration is just as good as it was in the 4.2 V8, and the 3.0 supercharged engine is significantly better on fuel consumption and CO2 levels, although you don't really buy an Audi S5 for either of those reasons, if you want good fuel economy figures and CO2 levels go and buy a 2.0 litre diesel A5 instead!
