We have the pleasure to offer this iconic "High Airbox" 1974 Ensign N174 Formula One car for sale.
Ensign Racing was founded in 1970 by British engineer and team principal Morris “Mo” Nunn. After establishing the marque in Formula 3, Nunn took the ambitious step into Formula One in 1973 with the Ensign N173, which made its World Championship debut at the French Grand Prix with Rikky von Opel. The N174, introduced for 1974, was therefore Ensign’s second Formula One design: an evolution of the N173, refined as the small, independent team developed its engineering and Grand Prix experience. Operating with limited resources against much larger manufacturers, Ensign became a distinctive part of the independent-constructor era of Formula One. Nunn remained closely associated with the team’s technical development before later building an outstanding career in American open-wheel racing, including championship-winning work in CART.
Chassis MN02 has an unusually extensive documented competition history, with World Championship appearances across the 1974, 1975 and 1976 seasons, followed by British Formula Libre, Shellsport and Aurora racing. Its period drivers included Brian Redman, Vern Schuppan, Roelof Wunderink, Gijs van Lennep and Chris Amon. The car’s subsequent return to historic competition gives it a particularly compelling link between the original Grand Prix era and today’s historic Formula One scene.
Rebuilt at the end of 2023 around a brand-new monocoque constructed by renowned racing engineer Massimo Pollino of Protech (Italy), with new mechanical components, MN02 is powered by a Cosworth DFV V8 last rebuilt by Richardson Engineering (UK). Protech has maintained the car since its reconstruction, with no expense spared. The original 1974 monocoque has been preserved and accompanies the car. Three dedicated documentation binders cover the 1974, 1975 and 1976 seasons.
Period competition & subsequent history (Detailed race history is below in the History section)
- 1974: MN02 was campaigned by Team Ensign. Brian Redman finished eighth in the non-championship International Trophy at Silverstone; Vern Schuppan finished 15th in the Belgian Grand Prix and also drove the car at Monaco and other Grands Prix. Mike Wilds drove later in the season.
- 1975: The car competed for the HB Bewaking-backed Ensign team, driven principally by Roelof Wunderink. Gijs van Lennep finished 10th at the Dutch Grand Prix.
- 1976: Chris Amon raced MN02 at the beginning of the season, taking fifth in the non-championship Race of Champions and eighth in the United States Grand Prix West at Long Beach. Later that year the car entered British Shellsport and libre events, driven by Guy Edwards, John Lepp and Mike Wilds, among others.
- 1979: MN02 appeared in Aurora British Formula One and other events with Robin Smith and Richard Jones. Jones crashed the car at Snetterton in May 1979. Published chassis research reports that the damaged car subsequently passed to George “Welly” Potter, who used its running gear in a Lotus Esprit project, leaving MN02 as an incomplete collection of parts.
At the end of 2022, MN02 was sold by UK collector Sid Hoole to its current owner who immediately commisioned a comprehensively rebuild around a brand-new monocoque constructed by renowned racing engineer Massimo Pollino of Protech (Italy), incorporating new mechanical components. The original 1974 monocoque survives and is included in the sale, providing an important physical link to the car’s period Formula One history. Since completion of the rebuild, MN02 has participated in the Masters Historic F1 race series and also at the Monaco Historic GP in 2024 and 2026 demonstrating the car's pace and reliability.
