Although this A3 is made up of some great individual ingredients, they don’t come together to produce a must-buy car. Unless you really need an automatic gearbox or can’t live without the head-turning looks of the S line trim, we’d save £4,200 and plump for the five-speed manual SE. It’s good to drive, still looks desirable, has plenty of standard equipment and, crucially, costs even less to run. It’s a winner.

Here's proof that green cars don’t have to be dull. This A3 S line looks like a hot hatch – but with Audi’s latest 1.6-litre diesel and stop-start, it’s cheap to run. For the first time, we’ve tried the eco-friendly motor with the super-efficient seven-speed S tronic twin-clutch box. How does it stand up?

Compared to the manual, there’s no performance penalty – 0-62mph takes only three-tenths longer, at 11.7 seconds, while the 121mph top speed is the same.

On the move, the auto works well, changing gears swiftly, while the torquey engine offers great refinement and punch. For extra pace, there’s a Sport mode, which holds on to gears longer before changing up. Plus, steering wheel paddles add to the appeal.

Factor in combined economy of 67.3mpg and CO2 emissions of 109g/km, and this Audi looks like a tempting choice. However, the auto doesn’t combine that well with stop-start. Once you’ve come to a halt, there can be too much of a delay between you demanding power and the engine firing up.

S line trim brings seven-spoke alloys, a roof spoiler and leather seats, giving the already smart-looking A3 extra visual appeal. But there’s a price to pay for standing out. When you specify the £1,450 S tronic transmission, this car costs nearly £23,000.
