Audi has introduced the A1 1.4 TFSI Cylinder-on-Demand (CoD) range priced from £16,740 for the 1.4 TFSI 140PS Sport (manual).
The Cylinder-on-Demand models can seamless switch between two cylinder and four cylinders in as little as 13 milliseconds in order to minimise fuel consumption – with up to 60.1 mpg on the combined cycle for the 1.4 140PS petrol engine. The 140PS unit is capable of 0-62 mph in 7.9 seconds, so it no slouch with a top speed of 132 mph.
According to the official combined cycle test the Sport, S line and Black Edition versions of the three-door Audi A1 can return up to 60.1 mpg with CO2 emissions of 109 g/km. The five-door A1 Sportback Sport models also record 60.1 mpg and 109 g/km, while S line and Black Edition versions are rated at 57.6 mpg with113g/km output.
All versions of the A1 and A1 Sportback are equipped initially with the seven-speed S tronic twin-clutch transmission, with manual transmission being available later in the year.
The Cylinder-on-Demand technology works using information from the throttle pedal sensors, it determines how the driver is driving, and if it detects an irregular pattern, for instance over a series of roundabouts or on a twisting A-road, it inhibits cylinder deactivation because here it would generally only be of short duration and wouldn't save any fuel. Two-cylinder operation is also disengaged if the driver brakes, enabling all four cylinders to support braking when coasting, and if the car is travelling downhill.
