Audi has revealed details of its mildly face-lifted A3 and A3 Sportback models.
They are due to go on sale this summer, with prices likely to remain unchanged, starting from around £15,500.
Four petrol and three diesel engines will be available, with improvements making them up to 15% more efficient.
The petrols range from 100bhp to 196bhp, and the diesels from 100bhp to 167bhp, although the highest-powered diesel won't be available until later in the year.
The engines are fitted to five- or six-speed manual gearboxes as standard, but the high-speed semi-automatic six- or seven-speed S tronic gearbox will be available as an option with most units.
Exterior changes include a more sculpted bonnet lid, front wings and updated bumpers. The headlamps are curved, and the exterior mirrors, door handles and alloy wheels have all been modified.
Interior tweaks include the use of more aluminium detailing, a refreshed instrument cluster design and a gearshift indicator that shows the most efficient gear to use. Buyers will also have a choice of more upholstery and fabric colours.
There are four trims: Standard, SE, Sport and S Line.
Standard cars have air-con, alloy wheels, electric windows, and a radio player.
SE adds a multi-function steering wheel, front foglamps and a different alloy wheel design.
Sport models have sports seats, sports suspension and 17-inch alloy wheels.
The top-level S line adds 18-inch alloys, a sportier body design, and black cloth and leather upholstery.
Options include automatic air-con, adaptive lights and parking sensors.
The Audi parking system is also available, which senses if a space is large enough for the car. It then operates the steering wheel to parallel-park the car, while the driver operates the accelerator, clutch and brakes.
Both the 2.0-litre petrol and highest-powered 2.0-litre diesel engines are available with Audi's Quattro four-wheel-drive system.
Buyers of the 1.8- or 2.0-litre petrol engines, or either 2.0-litre diesel, can also opt for Audi magnetic ride, which allows them to switch between normal and sport settings.
The options range for the A3 Sportback has also been expanded to include roof rails and a panoramic sunroof.
Like the A3, the S3's exterior design has been refreshed, with changes to the radiator grille, bumpers and roof spoiler.
Interior changes include new sports seats and revised aluminium pedals.
The S3 Sportback is now marketed as the second-top model in the range, alongside the three-door Audi S3.
Both are powered by a 260bhp 2.0-litre petrol engine with 258bhp of pulling power.
This powers the three-door car from 0-62mph in 5.7sec, 0.1sec faster than the Sportback. Top speed on both cars is limited to 155mph. Fuel consumption on each is 27.7mpg.
Other features include a six-speed manual gearbox, four-wheel-drive, 18-inch wheels, sports suspension and uprated brakes.
