Twin-charging comes to Audi's A1
TWINS, PLEASE: The Audi A1 is next in the VWAG family to receive power from the super- and turbocharged 1.4 TFSI.
Audi keeps it in the family by lifting VWAG’s neat little super-slash-turbocharged 1.4 TFSI and plugging it into the new A1.
Okay, so Audi may call it dual-charging, but it’s identical to the twin-charged TFSI engine first introduced here on VW's Scirocco. The top-performing A1 will be fitted with the clever engine that uses a combination of supercharging and turbocharging, working in sequence.
The petite 16-valve's supercharger is first to warm things up, stepping in at 1500rpm to increase thrust. After it disengages at around 2400rpm, the turbocharger takes over from around 3500rpm to provide added impetus.
TFSI PARTY: The twin-charged engine will soon be offered in a range of VWAG products on sale in SA.
This results in output of 138kW and 250Nm, with Audi quoting a 0 – 100km/h-time of 6.9 seconds and a top speed of 227km/h.
A seven-speed S tronic twin clutch transmission drives power to the front wheels.
Good news for South African fans is that this engine will be offered on the new A1 range, which will be launched here in the last week of January, from the second quarter of 2011.
The engine is also a key feature in VW's 132-kW Polo GTI, in South Africa from the second quarter of 2011.
