Fast, Fuel Efficient, Cheap. Normally you have to pick two. Fortunately, that is not the case with the Audi A1 Sport(if you buy second hand).
The 1.4 Twin Charged engine, coupled with the 7 speed twin-clutch VW-AG S-tronic gearbox is an amazing little package that fits perfectly with the little A1. It is a shame that they have phased it out and now replaced this engine with the 1.8 Turbo. The 1.4 has a very nice hissing noise from the turbo and a glorious raspy exhaust note all the way to 7000 RPM.
The car with a simple stage 1 ECU Remap from APR, makes the car sprint 0-100 in less than 6 seconds. The power sitting now at 150+kw, and 320nm of torque (in a 1100kg weight)This brings the car into a proper hot hatch territory. At the same time on a combined cycle the car is able to achieve average of 6L-7L/100km, and 5.2L/100km on highway!
The steering was one of the most impressive aspects to the A1 Sport. It is sharp and very precise. A lot of people compare this car to a polo GTI assuming that they would drive very similarly, surprisingly they are very different! The Audi is a bit harsher with stiffer suspension from factory, and the steering is much more responsive. The Audi really is great on a twisty mountain road and it always surprises people with how it keeps up with cars much higher price tags.
My overall opinion about the car is that: You really can have your cake, and eat it too!
