New technology boosts Audi A1 to 60mpg
The new Audi A1 will deliver up to 60mpg thanks to new engine technology that shuts part of itself down at lower speeds to save fuel.
The futuristic new technology, first seen on Audi's performance vehicles in the 'RS' ranges, is available in the form of a four-cylinder, 1.4-litre petrol engine.
However, when the Audi A1 is travelling at lower speeds or coasting the engine is capable of shutting down two cylinders to essentially turn the car into a two-cylinder vehicle for shorter periods.
The switch to two cylinders means the car uses up significantly less fuel than before and with careful driving can push fuel economy up to 60mpg.
Audi says the technology switches between active and deactivated cylinders within 13 to 35 milliseconds for almost instantaneous results.
For example, when the engine is working at lower speeds (1,400rpm to 3,000rpm) cylinders will automatically be deactivated. However, once the accelerator is pressed the cylinders are activated and the engine can fulfil its full sport potential.
The Audi A1 delivers 140PS when all four cylinders are firing and is capable of powering the car from 0-62mph in just 7.9 seconds.
The figures really begin to look impressive when compared to the 99Ps Ford Fiesta EcoBoost engine. The two-cylinder EcoBoost delivers up to 65mpg but offers less power than the Audi A1 option.
Audi has labelled the technology 'Cylinder on demand' (CoD) and will sell the engine option for £850 more than the standard 1.4-litre engine in the Audi A1.
Audi A1 1.4-litre CoD prices start from £16,740 and all models come with a seven-speed S tronic twin-clutch transmission.
The stylish supermini, winner of What Car? Car of the Year in 2011, is not the only Audi to get the new technology.
The Audi A1 Sportback will also be available with the CoD engine while the Audi A3 and the Audi A3 Sportback will also get the system from this year.
Prices for the new Audi A3 fitted with CoD technology start from £20,055 and all models are available to order now.
