• Turbocharged diesel features high pressure common rail injection and delivers up to 68.9mpg with the help of start-stop and energy recuperation systems. Linked to five-speed manual transmission only
• A3 1.6 TDI – 0-62mph in 11.4 seconds, top speed 121mph, 68.9mpg combined, 109g/km CO2 output
• A3 Cabriolet 1.6 TDI – 0-62mph in 12.2 seconds, top speed 118mph, 65.7mpg combined, 114g/km CO2 output
The three-door version’s 68.9mpg combined economy figure demands no sacrifices in power or performance – with the same 105PS and 250Nm peak power and torque outputs as the larger displacement 1.9-litre TDI unit, the new arrival powers the A3 1.6 TDI with five-speed manual transmission to 62mph in 11.4 seconds and on to a top speed of 121mph. This uncompromising breadth of ability is made possible with the help of automatic start-stop and energy recuperation systems, both of which made their debuts recently in the A3 1.4 TFSI.
The start-stop system cuts engine power at idle when the clutch pedal is released and the gear lever is in its neutral position, and then restarts in just two-tenths of a second – more rapidly than any other comparable system – when the clutch is depressed. With the system’s help, economy is boosted and CO2 is reduced by approximately 5g/km, but if required it can be deactivated at the touch of a button.
