Led by proud teacher Phil Worsley, the students, members of the young engineers club at Joseph Whitaker School in Rainworth, Nottinghamshire, shredded the existing record of 287mph set in 2011 when they put three model cars through their paces at Rolls-Royce’s test track at nearby Hucknall last weekend.
A team of schoolchildren has been conducting final tests for a world record attempt involving a rocket-powered model car.
