Audi has added an efficient new 1.4-litre Cylinder on Demand engine to the A1 and A3 line-ups. This new engine can shut down two of its four cylinders on light throttle loads to improve fuel consumption.
The 138bhp 1.4-litre TFSI CoD starts from £16,740 in the A1, offering fuel economy of 60.1mpg and CO2 emissions of 109g/km. Impressively, acceleration from 0-62mph takes just 7.9 seconds.
The A1 Sportback boasts the same figures as the three-door, and if you order S line or Black Edition models fuel economy stands at 57.6mpg, while CO2 emissions increase to 113g/km. All A1 CoD models come with a seven-speed dual-clutch gearbox but a six-speed manual will be made available later this year.
Meanwhile, the A3 CoD variants start from £20,055, which is £850 more than the existing 1.4 TFSI with 120bhp. The CoD A3s all come with a six-speed manual gearbox and claimed fuel economy of 60.1mpg. The three-door A3 can sprint from 0-62mph in 8.3 seconds, while the Sportback manages it in 8.4 seconds.
For comparison, the standard 120bhp 1.4 TFSI in the A3 allows for 0-62mph in 9.3 seconds, and boasts fuel consumption of 54.3mpg with CO2 emissions of 120g/km.
The A1 and A3 1.4 TFSI CoD models are available to order now.
