The headline here is the 60mpg CoD petrol engine that Audi are introducing to the A1 and A3 this year, but the point is to keep up with rivals like Ford who have already done the same thing with their EcoBoost range.
The new 1.4 litre engine that the German marque has developed is called Cylinder on Demand because the ECU shuts down two of the four cylinders when the engine’s full power isn’t required to save fuel. The TFSI CoD engine in a three-door A1 produces 138 hp and offers fuel economy of 60.1 mpg, and knocks out CO2 emissions of 109g/km. Acceleration from 0-62 mph is completed in a spritely 7.9 seconds. Choosing an A1 Sportback doesn’t affect the economy or acceleration but if you order an S Line or Black Edition model, the fuel economy is 57.6 mpg and the CO2 is 113g/km. Every A1 comes with a seven-speed DSG gearbox, although a six-speed manual option will be available later in the year.
The system operates using information from throttle pedal sensors to determine how the car’s being driven. The system is clever enough to removes any irregular pattern from its database so accelerating and decelerating for roundabouts are not counted as changes to the way the car is being driven.
The A3 CoD models start at £20,055 and each comes with six-speed manual transmission. The fuel economy of the bigger car is 60.1 mpg and the A3 accelerates to 62 mph in 8.3 seconds. The Sportback version is a tenth of a second slower to 62 mph. Both the A1 and A3 models are available to order now.
