Punto GT did 100 in 21 secs I think (Autocar).
But where the Punto gave the VTS a kicking was in overtaking power. It had 153lb/ft at 3000rpm (c.f. the 120? lb/ft at 4500? of the VTS).
As a result I think the GT did 50-70 in 3rd, 4th and 5th in 4.2, 5.6 and 7.9 respectively, which, as I recall, blew the VTS (and just about everything else) out of the water.
I also think the VTS (cos it revved to 7000+rpm) managed 60mph in 2nd gear and, accordingly, offered a very good 0-60mph figure - the Punto GT needed 3rd gear to get to 60, but still managed it in 7.7secs (I think) ...
Here come da judge...
