The new Audi A1 1.4 TFSI 185hp makes its world debut at the Paris Auto Show this month for delivery later this year. The 1.4-liter direct injection gasonline engine combines a supercharger that is active from 1500rpm, with a turbocharger adding its influence from around 3500rpm
The important numbers are: 185hp, 185 lb-ft, 0-62mph in 6.9 seconds, top speed 141mph, combined economy 40mpg US, CO2 139g/km The car will also get the S tronic twin-clutch transmission and S line specification as standard equipment.
Employing both supercharging and turbocharging for the first time in an Audi road car, the new compact and lightweight 4-vavle engine powering the A1 1.4 TFSI 185hp propels it from rest to 62mph in just 6.9 seconds. As the pace builds, the supercharger intervenes at 1500rpm to increase thrust, and in most cases disengages at 2400rpm, to be followed from around 3500rpm by the turbocharger spooling to provide another welcome surge.
As the supercharger takes care of low-range boost, it has been possible to use a larger turbocharger, designed with optimum efficiency in mind, which is reflected in impressively fuel economy and low emissions.
The light and compact seven-speed S tronic twin-clutch transmission fitted as standard to the top ranking A1 directs power to the front wheels. Composed of two transmission structures operated by two multi-plate clutches, it performs gear shifts in hundredths of a second, with no detectable interruption of power. The tall seventh gear reduces fuel consumption.
ESP with limited slip differential, McPherson strut front and torsion-beam rear suspension with separate springs and dampers, and taut S line settings forms the basis for agile handling, giving keen turn-in and impressive mid-corner stability and grip.
Speed modulation is taken care of very effectively by ventilated front disc brakes measuring 288mm in diameter and solid rear discs. Control is also safeguarded by the latest ESP stabilization program with electronic limited slip differential, which initiates very brief braking of the inside front wheel when its sensors detect an impending loss of traction during fast cornering.
The performance-oriented S line suspension forms part of the overall S line specification that will be standard for the 1.4 TFSI 185hp version, and includes features such as an exclusive S line exterior treatment, 17-inch wheels and part leather-upholstered sports seats.
