New Polo GTI takes on the Golf GTI

How do you prove one car is faster than another? You drag race them – duh!

The new Volkswagen Polo GTI isn't far off its Golf GTI stablemate these days in terms of power, but how does that translate in straight-line speed?

In this video, Car Mania aims to answer that question. The Polo GTI is smaller and lighter, though the Golf GTI has more grunt.

Power in both cars come from a 2.0-litre turbocharged four-cylinder petrol engine, making 147kW and 320Nm in the Polo GTI while the Golf GTI's unit makes a slightly meatier 169kW and 350Nm.

Claimed 0-100km/h times are 6.7 seconds for the Polo and 6.2 seconds for the Golf – as you can see, the gap between the two hot hatches has narrowed in recent years.

We won't keep you any longer. Have a watch of the video above to see which Volkswagen GTI hatchback is the quickest!
