If a car's torque peak is at 5000 rpm (typical of a modern petrol engine),
would it really get better mpg doing 5000 rpm in 1st gear at 25 mph, than
say 2000 rpm in 3rd gear at the same speed? Er, don't think so...


TBH, I'm not sure of any car with a reasonable sized engine that has
peak torque at 5krpm.

Peak torque is usually arround 3500-4000rpm, while on a diesel usually
arround 1700-2500rpm.

peak BHP on a normal family car with a petrol engine is normally arround
the 5-6krpm unless it is a VTEC/VVTi variable timing type engine in
which case it is higher.
