The story

A defining chapter in Lancia history.

Explore the ideas, engineering and context that shaped the Lancia Lambda, then continue into its specifications and place in the marque's lineage.

Origins

Vincenzo Lancia's account of the Lambda's origin has him standing on a ship's deck, noticing the strength of a hull built as a single structure, and asking why a car should be a body sitting on a separate chassis. Whether or not it happened that way, the car that resulted in 1922 broke with almost everything the industry then did. The Lambda had no separate frame. Its structure was a load-bearing steel body, narrow, low and rigid, into which the mechanical components were mounted directly. That removed the weight and flex of a ladder chassis, dropped the floor and therefore the whole car, and produced a machine that sat several inches lower than its contemporaries. It was not a monocoque in the modern stressed-skin sense, but the principle, that the body carries the loads, is the one every mass-produced car has followed since. Coachbuilders hated it, because there was nothing to build a body onto, and Lancia later offered a conventional chassis version to keep them supplied.

Design and engineering

The front suspension was equally unusual. Where the industry used beam axles on leaf springs, the Lambda had independent front suspension using a sliding pillar arrangement with a coil spring and hydraulic damper inside each vertical pillar, a design Lancia patented and continued using into the 1950s. Combined with the low centre of gravity and four-wheel brakes, it gave the car handling and ride quality that reviewers of the period struggled to find comparisons for.

In production

The engine was another Lancia peculiarity: a narrow-angle V4 with both banks under a single cylinder head, initially 2,119cc and later enlarged to 2,370 and 2,568cc. The narrow vee kept the unit short enough to suit the low, slim body, and Lancia used variations of the layout for decades.

Legacy

Production ran from 1922 to 1931 across nine series, with three-speed and later four-speed gearboxes, and around 13,000 were built. Four-wheel brakes were standard from the start, at a point when many manufacturers still braked only the rear axle, and the combination of low weight, low build and controlled wheel movement gave the Lambda an unusually high average speed on poor roads. It was expensive and never a volume car, and Lancia's decision to sell it to engineers rather than to fashion limited how far it travelled. Its influence, though, was structural in every sense: unitary construction and independent front suspension are now simply how cars are made. The Artena and Astura succeeded it, and Lancia's reputation for solving problems in ways nobody else had thought of dates precisely from here.
