A1 With Punch

18 January 2012


THE TURBOCHARGED 1.4—litre petrol engine quickly achieved a fine reputation for power allied to economy.



In standard form, the A1 version of this engine develops a nominal 122 PS (90 kW) at 5000 rpm, but when Superchips put this example on their dyno, they discovered that the actual output was better than this, 131 bhp (133 PS or 98 kW) at 5,665 rpm. This is not unusual: many Audi engines develop more than expected, and seldom less than the stated output. The same was true of the maximum torque which, for the standard engine, is claimed to be 200 Nm (148 lb.ft.) between 1500 and 4000 rpm. When tested on the Superchips dyno, it was found to be developing 210 Nm (155 lb.ft.) at 2369 rpm. It is very worthwhile to have the output tested in this way before any conversion takes place; one then has accurate benchmarks rather than simply comparing the increased power and torque with what is stated on paper.



The car was taken to Superchips in Buckingham where the ECU is removed from the car, opened up on the bench and reprogrammed.


After the me-mapping, the A1 went back on to the dyno and it was found that the power had gone up from 131 bhp (133 PS) to 152 bhp (154 PS) at 6323 rpm, and the maximum torque had increased from 210 Nm to 234 Nm at 2488 rpm.


So how does this translate into actual performance? We tested a standard A1 1.4 TFSI in March of this year and the figures allow us to make a valid comparison. As you can see from the table, the 0-60 and 70 mph times are reduced by 1.1 and 1.0 seconds respectively while the 0-80 mph time goes down by 1.5 seconds. When it came to acceleration on the move, the 30 to 50 mph times were reduced by 0.5 and 0.4 seconds in third and fourth gear respectively while the 50 to 70 mph times are all reduced, the most significant being a drop from 8.9 to 7.8 seconds in fifth gear.

During the test period, the A1 was driven briskly over a combination of A and B roads and motorways. The average fuel consumption over this period was exactly 45.0 mpg, not at all bad for a car which provided some thoroughly satisfying fast motoring, and a good indication that fuel consumption does not suffer as a result of engine re-mapping. This car had no other modifications, other than to the ECU, and proved fully capable, in terms of handling and braking, of dealing with the additional performance.

This Superchips conversion costs £455 for the A1 1.4 TFSI and you can find out more by contacting the company. Excerpt from Audi Driver Magazine
