By "big engine" I mean the 2.3 V5 and the V6 4Motion. Theyre big engines.
The Mk1, 2 and to a lesser extent the Mk3 Golf GTis were proper hot hatches for the hot hatch fan. I dont think that an off the shelf 2.0 115bhp Mk4 Golf GTi is really considered a hot hatch any more. Lets face it, VW dont exactly advertise the sporting prowess of these models becuase...erm...they dont have any.
All credit to VW, they helped invent the hot hatch genre (though not completely, as they claim - see Lotus Sunbeam, Renault 5 Gordini etc for earlier hot hatches/GTis). But the Mk4 Golf GTi/big engine range is not an enthusiast-aimed range. VW do not market the 2.0 as a "GTi" anywhere except the UK. Moreover, the V5 and V6 4 Motion have never been branded as hot hatches by VW. Rather, they are considered mile munchers and the chassis engineers would have worked harder to make better weight distribution and suspension to cope with the drivetrains extra weight if they were after a slice of the hot hatch market. In the end, they did. Hence we have the R32 - a mega hatch.
That leaves the 1.8T and the TDi GTi range. Now they are the core "hot hatch" range. With the TDi, VW are exploring a new genre and have made a hot hatch with a unique driving experience. Sadly, the Mk4 chassis is not exactly noted for its amazing handling (which is why the Mk5 will shadow the Focus suspension).
VW are the kings of PR and advertising. I have a GTi anniversary supplement from a magazine in the summer. They list some of the "pretenders to the GTi crown"...like the BX GTi, 1981 Fiat Abarth and XR3i! They rather conveniently ignored the GT Turbo, 205 GTi, 106 GTi, Clio 16v, Williams and pretty much any other good hot hatch! Interstingly, somewhere in the small print is the rather revealing fact that the supplement was sponsored by VW! What a suprise!
