Craig Henderson said Thursday he broke his world record for fuel economy, proving again that his aerodynamic Avion sports car can drive from border to border on a single tank of gas.
The Tacoma native started the venture Sunday, determined to show the car he built 25 years ago gets the most miles per gallon of any vehicle .
Over the 1,478-mile drive from Blaine to the Mexican border, Henderson said, he averaged 119.1 mpg. His 1986 world record was 103.7 mpg.
“I had butterflies for a while in my stomach thinking, ‘Are we going to make it? Is it going to break down?’ ” Henderson said Thursday. “All those things were going through my head.”
He steered the Avion to the Mexican border about 6 p.m. Wednesday. Henderson said he enjoyed the journey but will be shipping his car home to Bellingham rather than putting more miles on it.
He said that during the three-day trip the car used 12.4 gallons of gas. He had anticipated using about 14, though he brought 19 gallons with him.
Henderson and a friend designed and built the Avion 25 years ago, using recycled car parts and installing a small diesel engine.
“It’s kind of funny these are two guys who did this,” Henderson said. “Why can’t Detroit do this?”
