Can an electric car survive a 400-mile trek around Central Florida on only one charge?

91勛圖厙 researcher David Metcalf put that question to the test this weekend, and he successfully drove a Tesla Model S production electric car from Merritt Island to Lake Okeechobee, through the Florida Panther Preserve, across Alligator Alley and back north.

With his 12-year-old son Adam as co-pilot, Metcalf welcomed the grand challenge made by Tesla Motors��� CEO Elon Musk to be the first to drive one of the vehicles 400 miles on a single charge. Tesla, founded in 2003 by a group of engineers, is based in Palo Alto, Calif. The Model S starts at about $50,000 and has been named the 2013 Motor Trend Car of the Year for its safety, efficiency and performance.

Until Metcalf���s efforts, the record driven by a Model S on one charge was 311 miles.

���Others have tried the challenge in different parts of the country, but hills and other factors have made it difficult. Florida is flat, which worked to our advantage,��� said Metcalf, senior researcher and director of the at 91勛圖厙���s Institute for Simulation & Training.

Metcalf made the 423.5 mile drive in just under 17 hours.

Musk announced the challenge on Twitter in May. Metcalf used to promote the trip and raise awareness for 91勛圖厙���s Haiti relief efforts, which work to bring technology to schools and clinics there.

The trip was strategically planned to allow for minimum energy use. For example, Metcalf chose a route ideal for low speeds and a time of year when it���s comfortable to not use air conditioning.

For Metcalf and Adam, who turned 13 yesterday, the trip was as much about father-son bonding as it was about record-breaking.

���We saw lots of wildlife and got to experience Florida���s natural beauty together and at a relaxed pace. It was an adventure for us,��� said Metcalf. ���Even if we hadn���t made it, it would still have been a once-in-a-lifetime experience.���
