328i Introduction
The 1996 model year, 6 cylinder, 3 series vehicles are equipped with the new M52, 2.8 liter engine. The engine management system for the M52 engine is designated MS 41.1 which is manufactured by Siemens.
These vehicles are all designated 328;
- 328i - 4 door sedan,
- 328is - 2 door coupe,
- 328i Convertible
The new M52 engine is mated to either:
- S5D 310Z, (ZF type C) 5 speed manual gearbox as introduced on the 1995 M3. This manual gearbox has an increased torque rating to meet the needs of the new engine's increased torque output.
Gear Ratio
1st 4.20:1
2nd 2.49:1
3rd 1.66:1
4th 1.24:1
5th 1.00:1
Reverse 3.89:1
The gearbox ratios are slightly different compared with the previous Getrag S5D 250G. The final drive ratio of a manual gearbox equipped vehicle has been the changed from 3.15:1 to 2.93:1 for optimized fuel efficiency.
- A4S 270R, Turbo Hydramatic 4 speed automatic transmission. This transmission retains the same design and functions as the previous A4S 310 R. The reduced torque rating meets the requirements of the M52 engine while reducing costs. This transmission will replace the A4S 310 R in all 3 series vehicles including the 318i/is.
