The latest version of common rail diesel A3 with engine start-stop technology becomes the most efficient and economical option at its level in the sector.

The ongoing Audi crackdown on emissions has yielded another efficiency breakthrough within the A3 range, this time for the 140PS 2.0-litre TDI models which this month become the cleanest at their level in the premium sector. Thanks to the addition of engine start-stop and recuperation technology, the ever-popular common rail diesel three-door, five-door Sportback and Cabriolet variants benefit from major CO2 cuts of up to 20g/km or around 16 per cent, bringing output down to as little as 115g/km for three-door and Sportback versions.

In terms of company car taxation, this significant downward shift repositions the A3 2.0 TDI in the 13% BIK category, the movement from its original 18% position equating to a saving in annual tax liability of £373 for the three-door standard hatchback model, which will now cost a 40% tax payer £972.

The updated TDIs follow hot on the heels of the efficiency standard bearers for the A3 range – the 1.4 TFSI petrol models with emissions from 132g/km and the 1.6 TDIs with outputs of as little as 109g/km.
