Car mechanic Johnathan Goodwin converts some of America’s biggest gas-guzzlers into low-emission hybrids — while doubling the horsepower. If an engine tinkerer in Wichita, Kan., can turn out “mean and green” vehicles, why can’t Detroit?

An engineer's skill at turning gas guzzlers into efficient cars has led rock legends and big businesses to seek out his expertise.
Goodwin is making a name for himself -- and his company, H-Line Conversions -- by turning gas-guzzling behemoths like Hummers, Cadillac Escalades, Jeeps and other big American cars into clean-power machines.
Johnathan Goodwin can get 100 mpg out of a Lincoln Continental, cut emissions by 80%, and double the horsepower. Does the car business have the guts to follow him?
