I've been following the progress of Neil Young's "Linc Volt" project. Pretty cool concept and goal.
"Linc Volt is a 2.5 ton Lincoln Continental Mk IV convertible manufactured by Ford motors in 1959. At 19.5 feet long, it was the longest car of its era. A new series-hybrid system for powering the car is in the final stages of tuning and development."
"Young has spent more than $100,000 to green his 5,000-pound "Thinkin' Lincoln" former gas hog. "It's a piece of America art," said Young, who is an avid car collector. He hopes to get the equivalent of 100 miles per gallon and take the $10 million Progressive Insurance Automotive X Prize. "We are over halfway there (to 100 mph) with this car," he said."
