Pricing and running costs for the A3 Saloon are roughly in line with equivalent versions of the BMW 2 Series Gran Coupé and Mercedes A Class Saloon. What’s more, it will cost you a lot less than an Audi A4 or BMW 3 Series with the same sort of power and spec, whether you’re buying outright or on PCP finance.
On the other hand, our favourite version of the 3 Series – the 330e plug-in hybrid – makes a much cheaper company car than any A3 Saloon, thanks to its tiny CO2 emissions and plug-in hybrid tax breaks. If you are choosing an A3 Saloon as your next company car, think about petrol rather than diesel – the A3's diesels aren't RDE2 emissions compliant (unlike those of the A Class Saloon), and that means you'll pay a 4% surcharge.
The A3 Saloon comes with a three-year/60,000-mile warranty and three years’ roadside assistance – basically on a par with the industry norm. And you can pay a little extra to extend your A3's cover for up to five years or 90,000 miles.
We’d be tempted to do so, because Audi doesn’t have a brilliant record when it comes to reliability; it finished 22th out of 31 brands in the 2020 What Car? Reliability Survey. That is way below BMW (and a lot of non-premium brands, such as Ford, Mazda and Skoda) but still above Mercedes.
