GTI and GR difference is very big, GTI six generations, that is, now the market to buy the generation is the domestic golf high performance version of the front-wheel drive, the engine using cast aluminum 2.0t engine: EA888, tuned to 200 horsepower, that is, the more common head, Touguan, and other 2.0t models of the head, golf R is in the GTI based on the creation of a stronger High-performance version of the GTI (can be understood in this way, due to the history of the GTI series is much longer than the R system) has a Volkswagen 4-wheel drive system, a cast-iron engine, the model seems to be the EA113, is the last generation of the golf V gti engine (proving that this generation of the domestic GTI downsizing) this tuning out of 250 hp, and there is also a turbocharged kit is not the same, the GTI is the k03, the R is the k04. k03, R's is k04. Whether speed, handling, more than GTI a chip, not to mention the unique appearance of the R system, but the difference in price is great, I am the owner of the golf R (honestly, if this generation of GTI is still made in Germany, I will buy GTI, but the domestic production will not be able to give a force), have any questions you can ask me.
