BMW 1st Gear Speed Comparison - Automatic vs. Manual Transmission.

Submitted : Spring 2011

The purpose of this project is to compare the mph vs. time in 1^st gear of two 2002 BMW 325i sedans. While the year and model of both vehicles are identical the major difference between the two is the transmission, as one is an automatic and the other is manual. Using a dyno chart graph/table (see figure 4 of the appendix) and gear ratios for each vehicle, various equations, constants and conversions were used to produce a graph that directly compares the 1^st gear mph of both vehicles over a time interval.
