March 713M classic cars for sale

History of the March 713M

March Engineering introduced the 713M in 1971 as an evolution of its earlier Formula 3 designs. This British-built chassis was renowned for advancing aerodynamics in the junior single-seater categories. March rapidly became a dominant force in both Formula 2 and Formula 3, and the 713M was at the forefront of this push, benefiting from lessons learned in international competition and relentless development.

Model history of the March 713M

As the successor to the March 703 and 713, the 713M was created to address the handling, weight distribution, and structural rigidity improvements identified by drivers and engineers. The 'M' designation points to significant modifications over the basic 713, especially in the suspension and chassis. It remained in production mainly for the 1971 Formula 3 season, after which March’s next evolution—the 723—took the stage in Formula 3 racing.

Highlights of the March 713M

The March 713M is noted for its tubular spaceframe chassis, lightweight body, and finely tunable suspension, making it responsive and adaptable for various racing circuits. Its design reflects the transition from front-engined to rear-engined layouts in race car technology. Supply statistics are currently limited, but the low availability and focused demand within the classic motorsport community make the 713M a rare find among March race cars.

Technical Data

Special Editions and Collectible Models

There were no factory-recognised special editions of the 713M, as production focused on providing small teams and privateers with a capable Formula 3 machine. However, chassis with notable race histories or documented ownership by leading drivers from the era may carry higher collectibility.

Weak Spots and Common Issues

Racing machines like the March 713M demand regular inspection of the frame for stress cracks, attention to the suspension pick-up points, and routine safety scrutiny of fuel and brake systems. Given the car’s competitive history, buyers should verify the restoration quality and verify the car retains original components where possible.

Engine and Performance, Transmission and Handling

The March 713M typically delivers around 100–115 hp from its period-correct F3 engine. With a weight well below 500 kg, its power-to-weight ratio enables sharp acceleration and outstanding cornering speeds. Hewland gearboxes ensure quick, positive shifting. The fine-tuned balance and race-specific suspension geometry enabled the 713M to excel on tight European circuits, a fact appreciated by period drivers and historians alike. • 1971 March 713M – Usually fitted with Ford/Lotus Twin Cam or Toyota Novamotor engines; key for those seeking period authenticity in historic Formula 3 racing.

Interior, Comfort, Exterior and Design

The cockpit of the March 713M is radically minimalist—focused solely on function—featuring only the required instruments and controls for use on track. The exterior is defined by its sculpted alloy panels and purposeful, squat stance, a byproduct of its mid-engine layout and aerodynamic prioritisation. Colour schemes were largely determined by team sponsors or privateer preference, with no factory livery standards. Accessories or special features are rare; modifications and tuning are typically oriented toward track requirements rather than comfort or aesthetic luxury.

Other relevant features

Chassis numbers and race logbooks are especially important for verifying provenance. Given their competitive past, surviving original examples with clear historical records can be especially desirable for vintage racing events and historic motorsports gatherings.

Summary

The March 713M represents one of the most authentic ways to experience early 1970s Formula 3 racing technology. Its rare appearance on the market, lightweight engineering, and pure racing focus distinguish it as a machine built purely for speed, handling, and competition. Properly maintained, a 713M unlocks access to exclusive historic racing events and stands as a testament to the ingenuity of British racing engineering.
