Is there an RS3 sedan?
Overview. Audi’s smallest performance sedan is the RS3, but this little four-door is packed with performance and posh features. A turbocharged inline-five is the only engine option, making a heady 394 horsepower and a distinctive exhaust burble. The S3 is quick and engaging enough, but the shadow of Audi’s flagship RS3 looms large. At least in theory the RS is dynamically sharper and more engaging, giving the potential to be more rewarding. But then again, it’s also more expensive.Is an audi rs3 expensive to run? The audi rs3 is a performance car with lots of power, so there’s no denying it will cost you more in fuel during your ownership than a regular hatchback, insurance will be pricier, and some of the more bespoke upgrades could cost more to replace if things go wrong.Fuel consumption might not be your highest priority when considering a hot hatch as powerful as the Audi RS3, but it’s worth mentioning. Officially, the RS3 will return 31mpg – high 20s should be reasonable in everyday driving, but expect that to drop quickly if you’re making the most of the power on tap.
