The latest Audi A1 TDI has become even more efficient due to further optimisation of the fuel system and engine management unit resulting in a lower 99g/km CO2 output. With CO2 dipping below the 100g/km mark it is exempt from the London congestion charge, and also from Vehicle Excise Duty (VED) from year 2 onwards as the duty bandings currently stand.
The majority of Audi A1 models, including the 1.6 TDI, are already duty-free in the first year of ownership. The Audi A1 TDI returns 74.3mpg; it is capable of 0-62mpg in 10.5 seconds and can reach a top speed of 118mph.
The Audi A1 1.6 TDI with 99g output can be ordered in all three UK A1 trim levels; the SE, Sport and S line. Standard specification includes alloy wheels, remote central locking, air conditioning, electric front windows and mirrors and a six-speaker single CD audio system with auxiliary iPod connection linked to a 6.5-inch retractable display. Prices start from £14,480 rising to £17,865.
