These are no ordinary Golfs, though. Each one of these performance hatches has been heavily modified with hardware and software upgrades. Starting with the oldest of the trio, the Golf R MK6 comes with a 2.0-liter turbocharged engine with Stage 3 modifications, giving it a peak output of 450 horsepower (335 kilowatts). The improvements over the factory four-cylinder mill include new turbochargers, injectors, intercooler, exhaust system, high-pressure fuel pump, and many more. The result is a vehicle that looks somewhat subtle but hides a lot of power under the hood.
Next is the seventh-generation Golf in R form with a Stage 2 tuning kit for a maximum power of 420 hp (313 kW). This vehicle is from the facelifted version of the hatch and has a new intercooler and new ECU and TCU software. It may be a little down on power compared to the older Golf R in this race but it is the lightest of the trio, giving it a decent power-to-weight ratio of 287 hp per tonne.
Last but not least, there’s also the latest generation Golf R, also powered by a 2.0-liter inline-four-cylinder turbo engine. This is the least powerful contender in this competition as it only features Stage 1 modifications to the mill, which include a new carbon fiber intake and new ECU software. Being the newest of the bunch, it is also the heaviest with a power-to-weight ratio of 253 hp per tonne. All three cars have all-whee-drive systems and dual-clutch automatic transmissions.
So, which Golf R takes the win? This is a pretty tricky question. These three cars are very close in performance and the differences at the finish line are minimal. We won’t spoil the video and tell you the results but we’ll just say that the most powerful car is not always the fastest.
