By fitting its Audi A1 and A3 vehicles with Cylinder-on-Demand technology, the German manufacturer now appears to have two super-frugal models in its range.
Representing a perfect example of why less can sometimes mean more, the system in question allows the two cars to cut down on unnecessary mechanical effort and thus enable them to achieve fuel economy figures in excess of 60mpg, respectively.
To further highlight the green credentials of the new Audi A1 and A3, the former is able to limit its CO2 emissions to no more than 113g/km. At the same time, the A3’s CO2 emissions with the Cylinder-on Demand technology in place should never climb above 112g/km.
On the topic of eco-friendly driving, all versions mentioned are packed with Audi’s state-of-the-art engine stop-start system.
This device effectively cuts the car’s engine while it is at a standstill - while waiting at traffic lights or a junction for example - and then switches it back on without a hitch once a driver requests the vehicle to move once more.
Another intriguing feature of Audi’s new Cylinder-on-Demand technology is the fact that the device can switch between a two cylinder and a four cylinder operation in as little as 13 milliseconds.
From a driving standpoint, the Cylinder-on-Demand enabled Audi A1 - which will be made available in either a standard or five-door Sportback setup - can deliver a maximum torque of 250Nm at between 1,500 and 3,500rpm and the ability to go from 0-62mph in just eight seconds.
Meanwhile, the A3 and A3 Sportback is capable of topping 62mph from a standstill in an equally blistering 8.3 and 8.4 seconds, respectively. All classes are able to boast a top speed of 132mph.
