Born in Rothesay, Argyll and Bute, into one of Scotland's oldest aristocratic families and the descendant of a British Prime Minister, Bute was heir to a large fortune. He turned his back on an expensive education at Ampleforth College and set about pursuing a career in motor racing. In 1984, Bute, then known as Johnny Dumfries, was the sensation of the F3 season, scoring 14 race victories on his way to winning, and completely dominating, the British Formula 3 Championship for Team BP. He also finished runner-up to Ivan Capelli in the European Formula Three Championship that year. In 1985, he graduated to the newly created FIAInternational Formula 3000 Championship, initially competing for Onyx Race Engineering before switching to Lola Motorsport. It was a disappointing season, with a sixth-place finish in Vallelunga being the highlight of the year. In he made his breakthrough into F1, and raced a single season for the JPS Team Lotus. He was a late addition to the team, apparently as a result of Ayrton Senna not wanting Derek Warwick as a teammate. He competed in 15 Grands Prix for Lotus, which used the turbocharged Renault engines and scored 3 championship points. He was replaced for by the Japanese driver Satoru Nakajima as part of Lotus's deal to use Honda engines from that season onwards. During the most part of the season, he was usually one of the midfield drivers, on par with the Tyrrell drivers Martin Brundle and Philippe Streiff. In 1988, Bute scored the biggest racing victory of his career when he won the Le Mans 24 Hours, driving a Jaguar XJR-9 for Tom Walkinshaw's Silk Cut Jaguar Team alongside Dutchman Jan Lammers and Englishman Andy Wallace. Bute also participated in the 1-hour endurance race in the 1988 British Touring Car Championship at Donington Park with fellow ex-F1 Briton Guy Edwards for Andy Rouse's Kaliber Racing team in Ford Sierra RS500, finishing third overall and in Class A.
