MAX: Our Quest for a DIY 100-MPG Car

Progress continues on MAX, the home-built, 100-mpg car (prospectively) that you’ll be able to make for $10,000.

MAX on the road
MAX’s current body looks cool and classic, but its aerodynamic drag is holding MAX back from achieving 100 mpg. Jack and his team are confident they can re-design the body to cut its drag coefficient in half while still sticking to their $10,000 budget.
