Emissions tumble to 99 grams in new Audi A3 TDI

23 December 2009 - A new, efficient version of the Audi A3 1.6 TDI is available to order from this week. The exceptional frugality (99 g/km CO2) is available in one specific A3 configuration: the three-door body style equipped to Standard specification, priced at £18,005 OTR. All other variations of the 1.6 TDI continue to offer 68.9 mpg potential and 109g/km CO2 output.

The key elements responsible for the efficiency gains in the most focused 1.6 TDI to date include a modified final drive ratio for the standard five-speed manual transmission, a reduced ride height, under-body revisions to reduce aerodynamic drag and the use of slightly smaller 15-inch alloy wheels shod with low rolling resistance tyres.

These small but significant alterations combine with existing A3 1.6 TDI features including engine start-stop and energy recuperation systems. The start-stop system conserves fuel by cutting engine power at idle when the clutch pedal is released and the gear lever is in its neutral position, and then restarting when the clutch is depressed, while the recuperation function recycles a proportion of the wasted kinetic energy generated under normal braking and normally dissipated as heat, and stores this temporarily in the battery to reduce engine load when the car subsequently accelerates again.

Despite its combined economy figure of 74.3mpg and its road tax eliminating 99g/km CO2 output, the A3 1.6 TDI can draw on the same 105PS power output and 250Nm torque peak as all other versions, and consequently can match them on performance, clearing 62mph from rest in 11.4 seconds and offering the option to continue to 121mph where conditions allow.

The A3 1.6 TDI with 99g output will be available exclusively in Standard specification, which in this specific case includes 15-inch 7-arm design alloy wheels (normally 16-inch 7-arm design), manual air conditioning, remote central locking, electric front windows and a Chorus radio with single CD player. Versions equipped to SE, Sport and S line specification, and all Sportback models, continue to offer the class-leading 109g/km output and the potential to cover up to 68.9mpg (except the A3 Sportback 1.6 TDI S tronic with 112g/km output and 65.7mpg).
