M32 series 6 speed manual gear ratios
I was doing some Googling and found the gear ratios for a few different flavors of the M32 series 6 speed manual used in the Sonic and Cruze.
The MZ4 as fitted to all 2012 1.4T Sonics:
Final Drive/R&P: 3.65
1st: 3.82
2nd: 2.05
3rd: 1.30
4th: 0.96
5th: 0.74
6th: 0.61
The MF3 as fitted to the Cruze ECO:
Final Drive/R&P: 3.83
1st: 4.27
2nd: 2.16
3rd: 1.30
4th: 0.96
5th: 0.74
6th: 0.61
The MR5 as fitted to the regular 1.4T Cruze and Sonic RS:
Final Drive/R&P: 3.83 for Cruze. 4.18 for Sonic RS
1st: 4.27
2nd: 2.35
3rd: 1.48
4th: 1.07
5th: 0.88
6th: 0.74
The MZ0 as fitted to 1.8 Cruzes:
Final Drive/R&P: 3.94
1st: 3.82
2nd: 2.16
3rd: 1.48
4th: 1.07
5th: 0.88
6th: 0.74
I really wish they had put the MZ0 in the Sonic. It's 1st through 5th are very similar to my 85 Scirocco's close ratio box as well as being virtually the same as the European Opel Corsa OPC. Oh well, guess I'll just have to wait for the 1.8 Cruzes to start hitting the salvage yards.
