Straddling a 619-pound motorcycle, Scotty Pollacheck tucks in his knees and lowers his head as he waits for the green light. When he revs the engine, there's no roar. The bike moves so fast that within seconds all that's visible is a faint red taillight melting in the distance.

Pollacheck crosses the quarter-mile marker doing 156 mph; he's traveled 1,320 feet in 8.22 seconds, faster than any of the gas-powered cars, trucks or motorcycles that have raced in the drag sprints on this weekend at Portland International Raceway.

It's particularly impressive given Pollacheck is riding a vehicle that uses no gasoline and is powered entirely by lithium-ion batteries, according to the Associated Press.
