B20 - 1301roadItaly
Engine
2.0L V6 all-aluminium, ~100 bhp (with twin Solex carbs, competition exhaust and uprated camshaft)

Chassis B20-1301 is a 1951 first-series Lancia Aurelia B20 Coupé, one of the lightest and most sporting of the type, acquired new in Turin by American racing driver William 'Bill' Spear following his attendance at Le Mans in 1951. Delivered with a suite of Nardi and Jaeger special fittings unique to this car, it subsequently passed through the hands of Ferrari works driver Richie Ginther and renowned motorsport photographer Jesse Alexander before returning to long-term private custodianship. It retains original first-series aluminium bodywork details and is offered with the Nardi six-carburettor Dell'Orto induction set-up.

Maintenance & restoration

  1. Modification

    Car was fitted with a Nardi twin-Solex carburettor conversion, together with factory period competition exhaust manifolds and a higher-specification camshaft, yielding approximately 100 bhp — comparable to the specification of the lightweight competition B20s from 1952.

    The original Nardi six Dell'Orto carburettor set-up is retained and included with the car but not currently installed.

  2. Service

    Ongoing meticulous upkeep carried out by leading Lancia specialists based in Turin and in England, keeping the car in consistently reliable running condition.

    Work performed during Anthony MacLean's second period of ownership, covering roughly the fifteen years prior to the sale.
