What about the efficiency of a jet engine compared to a normal car engine of today? Lets say you wanted to build a car engine with about the same performance as todays engines. Lets say 200 Hp and a fuel consumption of 0,8 liters/10km (standard driving).
Would a jet engine perhaps something similar to an apu engine be suitable for this type of task?
Could it perhaps be a constant RPM engine driving a generation which in turn drives the car and charges batteries?
Also can you compare the propulsive efficiency of a jet engine to the efficiency of a normal engine?
