Hot on the heels of the all-new Audi A3 three-door hatch, the German firm is expanding the range with a practical five-door Sportback and a hot S3.

Both models will sit on the Audi stand at the Paris motorshow next week, with the three-door S3 set to grab the limelight.

The 2.0-litre TFSI motor in the all-wheel-drive S3 produces 296bhp and 379Nm of torque, some 35bhp and 30Nm more than the outgoing car. Audi claim the new 2.0-litre four-cylinder petrol engine will return a useful 40.9mpg on the combined cycle.

The new car is lighter than its predecessor, helping it hit 60mph from rest in five seconds when equipped with the S-Tronic dual clutch auto transmission, and 5.2 seconds with a manual – comfortably undercutting the old S3 and closing in on the super hot RS3.

Images of the more practical Sportback have also made a web appearance ahead of its French motor show debut. It shares much of the A3's styling but with an added pair of doors and roof rails.

It's roomier inside than its predecessor, offering more rear leg room thanks to a 58mm longer wheelbase and a boot capacity of 1,220 litres with the rear seats folded – 10 litres more than before.

In line with the new A3 three-door hatch, the Sportback is more efficient than the old car thanks to more economical engines and a 90kg weight loss.

Initially, only one diesel – the 2.0-litre TDI – and two petrol engines – 1.4 TFSI and 1.8-litre TFSI – will be available. A more powerful 2.0-litre diesel and a 1.6-litre diesel will be arriving later, as will an economical 1.2-litre TFSI petrol.

The Sportback will be going on sale next year, costing from £19,825, meaning those extra pair of doors and a tad more practicality cost an extra £620 over the three-door hatch.

UK pricing for the S3 is yet to released but it will go on sale in Germany from €38,900 or £31,000. Expect leather, LED lights and S Line trinkets to cost extra.
