Figure 3.2 Vehicle power plant torque-speed capability for large engines:
(a) V10 engine rated 373 kW and 3.33:1 driveline gear ratio,
(b) V12 engine rated 208 kW and 7.2:1 driveline gear ratio and
(c) V16 engine rated 746 kW and 2.23:1 driveline gear ratio
observation is that as power plant torque rating increases, the low to high gear ratio
also quickly converges to the value of 2:1. The third observation from this exercise
is that as power plant torque rating (maximum power rating) increases, the gear
