More researching on
http://www.automobile-catalog.com, 6sp gbox candidates seem to be:
6sp boxes with 4.07 final and 'taller' 5th - 15.91 8.78 6.02 4.56 3.65 3.11
Stilo 01-07, 1.2s as well as 1.4s
Bravo mk.2 1.4s
6sp, same 4.07 final but 'shorter' 5th - 15.91 8.78 6.02 4.56 3.75 3.11
Idea 06-12 1.4s
Panda 100HP 06-10
Grande Punto mk.3 16v 1.4s
Punto mk.2-and-a-half Sporting 1.4
This compares with 5sp Punto boxes:
Punto mk.2 and 2-and-a-half - with 'tall' 3.44 final and the 'taller' 5th - 13.45 7.42 5.09 3.86 3.09
Punto mk.1 - back to the 'short' 4.07 final and same 'taller' 5th - 15.91 8.78 6.02 4.56 3.65
That 'tall' mk.2 box explains a lot about the mk.2's disappointing character, while the 'short' mk.1 box is delightful! All it lacks is a M-way 'overdrive' top, which any of the 6sps will provide. Pity it doesn't bring ratios closer lower down.
The only g'box question is - 'tall' or 'short' 5th? Better to be closer-ratio with 4th, or 6th? The numerical difference is small, but I think would feel different. With the 'short' 5th you'd be at 4500rpm (peak torque) in 5th, the 'long' one at only 4380 - significantly down the power curve.
Punto mk.1 Cabrio/Sporting has 165/65x14s, 1015kg.
Now to work out how this 95PS rig would be in a 770kg Uno SX70! with 165/70x13s, just 1.5% smaller rolling radius (note - a UT weighs 895kg).
