If i wanted a fast FWD hatch i would happily buy the R26R! Will be more fun than any gti (or any other hatch inc the R32) will be (no matter how remapped) I can think of better cars for the money that will do a better job though.
The R26R is an everyday hatch, its a special edition like the ED30 thats all. Hell, my old ctr was hardcore compared to the GTI, the only luxury was aircon, electric windows and heated mirrors were introduced on the facelift!
The V6 is not hardcore, the mk2 was also much better at handling than the mk1.
Calling the GTI hardcore is a ridiculous statement, its a comfy cruiser with loads of luxuries, large alloy wheels and alot of weight!
Defenition of hardcore hothatch:
Low weight, good power (nice bhp/ton figure)
minimal options
bare interior
purpose built seats for support over comfort
LSD
minimal electronics (less to go wrong and less weight)
Basically everything the GTI isnt (or the focus st, vxr, civic type r, r32, cupra r, cooper s etc)
