Epic.
If you paint the front of your house, maybe put an extension on it and rejig the kitchen, maybe move some internal walls ... its still the same house?
I don't understand whats so hard to comprehend about the fact that the mk5 and mk6 share a lot of parts, the same platform which is what defines to a great extent the dimensions of the car and its handling.
No one is saying they are identical. The Mk6 is a revised and for the most part impoved evolution of the mk5. But strip back the body skin and the plastics of the interior and you have, essentially, the same car.
Most of the engines in the Mk6 line up are identical to those in the mk5 line up. In fact the very very latest mk5 GTI's have the same engine as the mk6 GTI as it was released in the Mk5's lifetime. Mechanically I would say the biggest difference is the mag shocks used in models with ACC but thats a bolt on component that if someone had the inclination to do it could be retrofitted to the Mk5 (same platform (PQ35) after all....). Bit of a bugger with the necessary control systems etc but most likely doable.
Only GTI I know of that has the MK6 engine is the ED30. We should be talking straight mk5 GTi and mk6 GTi differences.
I'll assume most of this.
We both have 2 eyes, 10 fingers and toes, 2 arms and legs yet are we the same as girls ? Assuming I'm talking to a bloke here.
Wrong. The ED30 engine is completely different to the MK6 GTI engine (but is planned for the Golf R with some tweaks).
I am talking about the GTI, the very latest ones made in the last year of production, and only the last couple of hundred to roll off the production line at that, have the same engine as the MK6 GTI. The point being that the engine doesn't make the car.
