Cars that get over 40 miles per gallon in fuel efficiency are, reportedly, becoming all the rage, with more models from American and foreign car makers being introduced at the latest Detroit Auto Show.
So I got curious, having just started a 18-mile-each-way commute, what exactly are the savings one can achieve by buying a more fuel efficient car? I assumed a situation faily like mine: My car is paid for and costs me only minimal maintenance to keep up (a 14-year-old Toyota Camry) and a 20 mile each way commute.
Say you’re considering buying a new car which gets 40mpg for $20,000. That seems moderately standard for these cars. Assume a 40 mile daily round trip commute, and an additional 40 miles of weekend or additional driving. Assuming a current care actual efficiency of 20mpg. Assume the price of gas goes up to $4/gal. How long would it take for you to make up the cost of that new car in fuel savings?
