I don't know. Engines and transmissions have plenty of solenoids these days. Fuel injectors, idle air control etc. which seem pretty durable to me. By using pwm you can precisely control the current just like you do with dc motors avoiding excess heat. What I like is you could switch the engine from power mode to economy mode really easily, disable cylinders for better mpg. Maybe even some advantages no one has even thought about when using direct injection.
