One of the most memorable Lancias ever, the Fuorilegge was conceived by noted British specialists Thornley Kelham as "a really cool, not-one-for-the-purists, heavily modified B20GT," in their words. "It fit with our aim to put Aurelias on the map [by] developing a set of ideas to create a unique Aurelia interpretation."

Beginning with a nearly hopeless B20, the car was transplanted onto a Flaminia drivetrain, the engine bored out to 2.8 liters and blessed with hotter camshafts, fuel injection, and a custom exhaust for more power - about 175 horsepower, more or less. The four-speed transaxle was also sourced from a Flaminia and offers much taller gearing to give the car greater legs. The body was tweaked throughout in the style of a famed B20GT that won class victories at the Mille Miglia and 24 Hours of Le Mans, with the roofline lowered extensively for aerodynamics, the fenders widened, turn indicators moved into the headlights, a large scoop added to the hood, and the suspension modified. The interior was outfitted with Porsche Speedster-style seats, Alcantara headlining, and an integrated FIA-specification roll cage.
