My daily driver is a Scion xB which weighs in at 3400 pounds running the AC51/144 volt system, it makes a great commuter vehicle. Top speed is 90+. Brian
To clarify, by "the new 144 volt system" I think Brian means the new AC51 motor and the new 144V nominal controller, not the new controller and the AC50 which would only have about 80 ft-lb peak torque with the new controller peak current of 500A (please correct if wrong Brian). I realize he did not say the latter, but since the OP mentioned the AC50 it might be taken that way.
Brian will likely get some arguments here that it would "work well in S10's and Rangers", since a number of folks here think "work well" means 0 to 60 mph in less than 12 seconds.
Maybe better to give numbers. I can give some indication, my 2260 lb Swift does 0 to 60 mph in 16 seconds (three shifts) with 90 ft-lb peak torque from the AC50 with 550A controller. The truck might weigh what, 50% more, and the AC51/144V would give 22% greater peak torque. I would guess the OP would be looking at 0 to 60 mph time in the low 20's seconds. Which might be just fine to him, or not.
