TDIe. The ‘e’ is for efficient
The most efficient engine in the Audi A4 range, in fact, with a combined 65.7mpg. But that doesn’t mean a lack of performance. Installed in the A4 Saloon, this 2.0-litre TDIe engine will produce 136PS and 320 Nm of torque, a 0–62 time of 9.3 seconds and a top speed of 134mph. Yet CO2 emissions are remarkably low: just 112g/km, meaning your road tax liability will be lower.
