Audi A1 quattro: Prototype driving report

Audi A1 quattro

Great exclusive driving report here with a prototype of the Audi A1 quattro. A must read!

It’s the familiar 1.4-litre Twincharger engine from the VW Group, but in Audi oh-so-slightly-different guise. In the Polo GTI/Fabia vRS/Ibiza Cupra the super- and turbocharged four-cylinder petrol is good for 178bhp at 6200rpm and 184lb ft from 2000-4500rpm, but because Audi’s little hot hatch has to top the range it has an extra four bhp.

The supercharger toils away at low revs (it works from 1500rpm, and in most situations it’s disengaged by 2400rpm), while the turbo takes over by 3500rpm, and Audi says its high-rev usage means in can be larger and designed for efficiency. 

Which all sounds very clever, and in the front-wheel drive, dual-clutch transmission-equipped production A1 1.4 TSFI equals figures of 47.9mpg and 139g/km.
