Costs & verdict
Everyday costs, plus how reliable and safe it is
Costs, insurance groups, MPG and CO2
The A3 carries a slight price premium over equivalent versions of the BMW 1 Series and Mercedes A-Class, but there isn’t a lot in it. How well the car will hold onto its value, and how competitive the PCP finance deals are for it, remain to be seen.
The engines offer fuel official economy and CO2 emissions in line with what you can expect from equivalents from Mercedes and BMW. Unsurprisingly, the best fuel economy and lowest CO2 emissions are found from the diesel engines. Company car users might want to sit tight until the plug-in hybrid version arrives, with the possibility of lower Benefit-in-Kind tax.
Equipment, options and extras
The three core trim levels are all impressively equipped, and entry-level Technik trim represents the best value overall, giving you cruise control, rear parking sensors and LED headlights. Go up to Sport and you get dual-zone climate control, a leather interior and electrically folding door mirrors. Top-spec S line gets sporty styling touches, as well as front sports seats.
Audi doesn’t have a brilliant record when it comes to reliability; it finished 20th out of 31 brands in the 2019 What Car Reliability Survey. The A3 comes with a three-year/60,000-mile warranty and three years’ roadside assistance as standard – basically on a par with the industry norm. You can pay a little extra to extend your A3 Sportback's cover for up to five years or 90,000 miles.
Safety and security
Every A3 has automatic emergency braking (AEB) and lane departure warning as standard. It hasn’t been independently tested by safety experts Euro NCAP yet, but the Volkswagen Golf – which is very similar underneath – achieved the full five-star verdict.
