A restored 1937 Hudson Terraplane packing a modern LS3 V8 has surfaced for sale on Hagerty Marketplace, pairing Depression-era style with a fully modern chassis underneath. The coupe is currently up for auction, with bidding already well underway.The 1937 Hudson Terraplane, finished in metallic blue over tan upholstery. Photo: Hagerty MarketplaceHudson built its reputation in the 1930s on cars that could out-run rivals costing far more, and the Terraplane line was the sharpest expression of that idea. Riding on a lighter platform than Hudson's full-size models, the Terraplane carried a stepped-back greenhouse and flowing fenders that made it one of the more distinctive shapes on American roads, while its lighter weight made it a genuine threat in early stock car and hillclimb competition.This particular example carries that spirit into the present day. The body sits on a custom Art Morrison chassis with a triangulated four-bar rear suspension and JRI valved coilovers at all four corners, while rack-and-pinion steering and a Ford 9-inch rear end replace the factory underpinnings entirely. Stopping power comes from 11-inch Wilwood disc brakes at every corner, mounted on Wilwood Pro Spindles up front.The Art Morrison chassis and Ford 9-inch rear end sit beneath a Wilwood disc brake setup at all four corners.

It's the kind of drivetrain swap that's become a hallmark of serious prewar builds, trading a flathead six for genuine highway manners without erasing the car's period character. Two small but telling details survive from the original car: the running boards were refurbished by Kris Arneson at Running Board Rubber Company in Canada, and the steering wheel was refinished by Pat and Sam Sawfield at Pearlcraft Steering Wheels in Australia.AdvertisementAdvertisementInside, the cabin mixes tan upholstery with a body-color dashboard, a Classic Instruments cluster, and sound deadening added throughout to quiet the ride. Vintage Air handles climate control, while a JVC head unit, a Kicker 10-inch subwoofer, four Rockford Fosgate 6x9 speakers, and three Rockford Fosgate amplifiers make up a sound system well beyond anything Hudson ever offered from the factory.The refinished dashboard and steering wheel keep period character amid the modern upgrades.

According to the listing, the only notable flaw is a pair of inoperative windshield wipers, and the sale includes refurbishment photos, a show placard, and an owner's manual documenting the build.15-inch Hot Rod wire wheels and BFGoodrich whitewalls finish off the period-correct exterior look.
