The Alfa GTV 96-04 weighed in at 1415kg, the zed is 1545kg (276 GT Model). Comparing HP and TQ, the Alfa had 218bhp v 276bhp, with TQ for the Alfa at 195ftlb v 268 of the Zed, so I'd say their performance is no better than a Zed, as per the figures. Especially with 0-60 a whole second behind.
Golf R32 3dr DSG (05-08), Weighing 1538kg and providing 246bhp and TQ 236, again another under performing vehicle. 0-60 with the DSG gives it 6.0s, with the non DSG 6.3s.
Neither are better performing........
In my eyes both would be left at the drag strip. They might sound better, but that's just a matter of opinion etc.
I looked at the GTV and R32, both dismissed for the better car...... the Zed.
