Electric car completes epic journey

A zero CO2 emission electric car developed by British engineers has completed a 16,000-mile journey travelling from near the Arctic Circle in Alaska to the world's southernmost city.

The SRZero sportscar, developed by engineers from Imperial College London, drove for 70 days through 14 countries including the Rocky Mountains in Mexico to finish its trip on the Panamerican Highway.

The vehicle, powered by two electric motors running on lithium iron phosphate batteries, began its trip on July 3 in Chena Hot Springs, Alaska, after charging its batteries using geothermal energy.

Trip organiser Alex Schey, who is a mechanical engineer, wrote on his blog: "The SRZero was literally being charged from energy taken straight out of the earth with absolutely zero CO2 emissions."

Hitting the brakes helped the car recover kinetic energy and extended its driving capacity to six hours - more than 250 miles - on a single charge.

According to the team, the vehicle achieved peak outputs of 400 horsepower and reached 60mph (96kph) in just seven seconds, clocking top controlled speeds of 124mph (200kph).

Andy Hadland, spokesman for the team, said he hoped the trip would change the image of electric cars and inspire young people to become engineers and develop their own projects.
