Audi is to introduce a new ‘ultra’ efficient diesel engine across its range of A4, A5 and A6 models.
The 2.0-litre TDI engine comes with a number of different of power outputs from 136hp to 190hp. CO2 emissions range from 104g/km to 119g/km.
The new engine will make for the most economical Audis ever, with an economy figure of 61.4mpg for the A6 Avant, rising to 72.4mpg for the A4 saloon.
That A4 TDI Ultra also now has a BMW 3 Series-beating CO2 figure of 104g/km: the best 3 Series EfficientDynamics can only manage 109g/km.
The engine isn’t lacking in performance either, with 62mph being hit in 8.2 seconds in the 190hp A6 saloon with the S tronic transmission. The 136hp A4 saloon, meanwhile, will reach 62mph in 9.3 seconds.
Prices for the UK are yet to be confirmed, but in Europe the A4 starts at €32,600 (around £27,000) with the 136hp engine.
Audi board member for development (and father of, amongst others, the Volkswagen Up), Prof. Dr. Ulrich Hackenberg said: “The latest TDI technology, ultra-efficient transmissions, advanced exhaust aftertreatment – customers will hardly see anything, but they’ll notice the effects of powerful acceleration and, thanks to extremely low fuel consumption, when paying at the gas station.
“The Audi ultra models score points with big advantages for everyday operation – just what customers appreciate.”
