In fact no matter how well we engineer them there s fundamental limitations in how efficient an engine can run.
Electric motor drivetrain.
Electric motors can have efficiencies of more than 90 compared to that of an ice which usually is about 25 50 efficient.
The chevrolet volt has two electric motors one is 96 percent efficient while the other is 94 percent efficient.
Nitz says electric motor efficiency at gm is measured in two ways.
Diyev has designed several electric motor drivetrain kits that you just bolt it to the existing ice engine mounts.
Diyev engineers have developed a new kind of all electric drivetrain and battery module system for small medium and large trucks and buses that are very easy to use install maintain and understand.
More specifically the drivetrain measures 23 6 inches wide 17 3 inches deep and only 11 02 inches tall.
Finally an electric crate motor you can drop into your old car.
No matter how hard we try we will never be able to be as efficient as a simple electric motor.
