Most GM Authority readers are well-aware of the annual Holley LS Fest, an annual car show open to vehicles that either came with GM LS V8 engines, or had one of the automaker’s venerable Small Blocks swapped into it at some point. The well-known aftermarket company recently held a similar enthusiast gathering dubbed the Holley High Voltage Experience, a two-day summit that attracted customized EVs, as well as EV-swapped vintage vehicles like this 1966 Cadillac Coupe DeVille.
Built by Arizona-based shop Legacy EV, this drop-top Caddy started out life as a V8-powered Coupe DeVille Convertible. It was later purchased by the CEO of Legacy EV, who had the idea to convert the car into an EV to help promote the company’s business at cars and coffee events, industry trade shows and more. It now features three Netgain Hyper 9 electric motors in place of the 429 cubic-inch V8, which have been linked together in series and produce an estimated 1,000 pound-feet of torque at the rear differential.
The battery pack is a custom setup developed and built by Legacy EV, with range sitting at an estimated 100 miles. This isn’t enough for most drivers, even for a weekend cruiser, however Legacy EV wasn’t particularly concerned about the vehicle’s range, as it’s mostly used as a promotional tool. Other modifications include full adjustable air-ride suspension, custom Cadillac-style wheels and aftermarket whitewall tires.
Holley said Legacy EV’s unique conversion car was a hit at the High Voltage Experience, which was held at Sonoma Raceway in California on July 9th and 10th.
“There were faster cars at Holley’s High Voltage Experience,” the company said of this unique Caddy. “There were cars that had longer ranges, and cars that could carry more people. But none of them could match [the] cool factor of a droptop Cadillac on bags. By far and wide a favorite this year, Legacy EV’s Caddy was the one everybody wanted to be seen in, cruising alongside the bay at sunset.”
