Car exhaust can smell like rotten eggs when the fuel has a lot of sulphur in it.
Being a hybrid or fully electric car makes a car quite efficient. Also a lot of factors determine how much fuel effienciency a car has. Such as weight, tire pressure and speed.

There are a lot of things that you can do to reduce fuel consumption in your car, brake in plenty of time- do not brake harshly at the last second.
