LincVolt
Neil Young has taken his 1959 Lincoln Continental convertible and had it converted to run on new power sources, rather than the 7+ litre petrol engine it used to use.
Young saw many small cars being converted to run on electric power, but wanted to do the same to a large car... and man is it big, measuring in at 19.5 feet long and weighs 2.5 tons.
Here’s a video of Neil Young explaining it
