I have no degree, but in my opinion, cars really havent come that far in the past 100 years. Most engines and systems that come with it have been the same for the past 50 years. Most new cars have a crapton on circuitry, but most the power systems are the same. Alot of new cars elimintaed the driveshaft woth the Trans Axle (transmission and rear axle). I think hybrid techmology is subpar, considering how much info there is of Electro motive forces. I think there is much.more room for improvement, not.only in.the efficeny.field, but the power output to.
