Boro was a Dutch Formula One constructor that competed in the 1976 and 1977 Formula One World Championships. Operated by brothers Bob and Rody Hoogenboom, the team emerged from an unusual legal dispute involving the British constructor Ensign and ultimately became one of the many short-lived private teams that characterised Formula One during the 1970s.

Although Boro contested only eight World Championship Grands Prix, the team is remembered for its unique origins and its transformation of an existing Ensign chassis into an independent Formula One entry.
Origins
The origins of Boro can be traced to the Ensign N175, a Formula One chassis designed by British constructor Ensign under team owner Morris Nunn. During the 1975 season, the car was sponsored by the Dutch security company HB Bewaking, which was backed by entrepreneurs Bob and Rody Hoogenboom. When financial disagreements arose between Ensign and the sponsors, ownership of the chassis became the subject of legal proceedings.
The dispute ultimately resulted in HB Bewaking taking possession of the Formula One car. Rather than returning it to Ensign or selling it, the Hoogenboom brothers decided to establish their own Formula One operation. The car was subsequently renamed Boro, a name created by combining the brothers’ first names—BOb and ROdy.
To support the project, the brothers established a workshop in Bovenkerk, in the Dutch province of North Holland, where the Ensign-derived chassis was prepared and developed for Grand Prix competition.
Formula One
Boro made its Formula One debut during the 1976 season, entering the renamed Boro N175, which remained fundamentally based on the original Ensign design. Powered by the widely used Ford Cosworth DFV V8 engine, the car was mechanically similar to many independent Formula One entries of the era, although limited financial resources restricted its development throughout its career.
The team’s principal driver was Australian Larry Perkins, who had previously raced for Ensign before following the chassis to the newly established Dutch team. Perkins gave Boro its best-ever World Championship result by finishing eighth at the 1976 Belgian Grand Prix. While the finish did not yield championship points under the scoring system used at the time, it demonstrated that the small independent team was capable of reaching the chequered flag against much stronger opposition.
Despite occasional flashes of competitiveness, Boro struggled to establish itself in an increasingly professional Formula One environment. The team entered a total of eight World Championship Grands Prix across the 1976 and 1977 seasons, but qualified inconsistently and suffered from persistent reliability and financial difficulties. Only two race finishes were recorded during its entire Formula One campaign, with Perkins’ eighth place in Belgium remaining the constructor’s highest achievement.
Legacy
Following the 1977 season, Boro withdrew from Formula One as mounting costs and limited sponsorship made continued participation unsustainable. Like many small independent constructors of the era, the team lacked the financial and technical resources necessary to compete consistently against established manufacturers such as Ferrari, Lotus, McLaren, Brabham, and Tyrrell.
Although Boro’s Formula One career was brief, the team occupies a unique place in F1 history. It remains one of the few constructors to have been created as the direct result of a legal ownership dispute over an existing Formula One chassis. The project also represented a rare Dutch constructor in Formula One during a period when the championship was dominated by British and Italian teams.
