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. Pollacheck and his bike - dubbed the KillaCycle - are part of a growing movement that's exploiting breakthroughs in battery technology and could soon challenge the world's fastest-accelerating vehicles in the $1 billion drag-racing industry. In professional drag racing I expect to see the electrics eventually pass up the fuel dragsters," said Dick Brown, president of AeroBatteries, which sponsors White Zombie, the world's quickest-accelerating street-legal electric car - a 1972 white Datsun 1200. "Electric gives you instant torque whereas gasoline you have to build up," Brown said. The KillaCycle runs on 990 lithium-ion battery cells that feed two direct current motors, generating 350 horsepower. The bike accelerates from zero to 60 mph in just under a second - faster than many professional gas-powered drag motorcycles and within striking distance of the quickest bikes that run on nitromethane. With that hyper-potent racing fuel, riders can get to 60 mph in 0.7 seconds.
