ABT Sportsline has revealed a massive power hike for the 2014 Audi S1 Sportback.

As if the standard Audi S1 wasn't already a little monster with its 231 PS (170 kW) output in such a small package, ABT is raising the stakes with a power bump for the four-cylinder 2.0-liter TFSI engine. After ABT applied its know-how, the engine is now capable of developing no less than 310 PS (228 kW) and 440 Nm (324 lb-ft).

Besides the added oomph, the S1 Sportback seen here has custom springs lowering the ride height by 30mm while for shoes the tuner went for an 18-inch gun metal set wrapped around in 225/50 R18 sports tires. Other changes include fender inserts along with built-in entrance lights and bespoke floor mats.

Performance details have not been released but this tuned S1 should be a tad quicker than the standard version which needs 5.9 seconds until 62 mph (100 km/h) before hitting an electronically-capped top speed of 155 mph (250 km/h). Needless to say, ABT is offering this upgrade package also for the three-door S1.
