Geneva Motor Show 2014: Audi to debut 228bhp S1 hot hatch

The launch of the three-door Audi S1 and the S1 Sportback means Audi has kept its promise to turn the limited-edition Audi A1 Quattro into a fully fledged series-production model.

Powering the Audi S1 is a turbocharged 2.0-litre, four-cylinder petrol engine, which delivers 228bhp and 37.7kgm of torque. That’s 24bhp less but 2kgm more than the older ‘EA113’ turbocharged 2.0-litre petrol engine used in the A1 Quattro, which was produced in limited numbers in 2012.

 

The Audi S1 will come with a six-speed manual transmission, plus a Haldex-style multi-plate-clutch four-wheel drive system. An electronic differential lock has been incorporated within a two-stage electronic stability control system to limit wheelspin and further enhance traction. Audi quotes a 0-100kph time of 5.8sec for the three-door S1 and 5.9sec for the heavier five-door S1 Sportback. Top speed for both is limited to 250kph. 

 

Underpinning both S1 models is a revised version of the standard A1’s MacPherson strut front suspension, but with a number of detailed changes, in combination with a revamped electro-mechanical steering system. A new four-link arrangement replaces the torsion beam set-up used on lesser A1 models, providing improvements in wheel control.  

 

Equipment will include variable damper control, 17-inch wheels shod with 215/40 tyres and Audi’s Drive Select system, which allows the driver to alter the mapping of the throttle, dampers and steering. The braking set-up includes upgraded 310mm front discs. Among the optional features are 18-inch wheels with more aggressive 225/35 rubber and red brake calipers.

Xenon headlamps, LED tail-lamps, wider sills and modified bumpers all feature. Four new colours, including the yellow of the car pictured here, complement the changes. However, don’t expect the S1, or indeed the A1 it’s based on, to feature in Audi’s Indian line-up anytime soon. For now, the most affordable Audi model in India will be the Audi A3 sedan that will be launched soon.
