This number is only factoring gas as a energy source. The combined mpg (what they call it when they calculate electric usage too) is easily over 150 mpg which is “cheating”. But to put it into perspective, my car can run over 400 miles on a 11 gallon tank without ever touching an electric outlet.
Small hybrids like a Prius can go over 50 mpg consistently. Hybrids are so good from a gas standpoint. At these gas prices, it’s a no brainer to get a hybrid IMO.
