Thursday was scrutineering and final practice running, all awash with rain. Hill did not think much of us bunch of amateurs with this “tiddly little car.” BRM mechanics were excellent and helpful with our poor knowledge of racing and car preparation for this sort of thing.
The 1963 Rover-brm team was lead by Wilkie Wilkinson from BRM, and he was joined by Barnard, Candy and, in the pits, Fred Court and George Perry.
In the event, the Rover-brm’s gas turbine reached 38– 40,000rpm along the Mulsanne Straight for a road speed of around 225–240kph. The car completed 4165km (2588 miles) during the 24-hour race at an average speed of 173.4kph/107.8mph, with Ginther setting the fastest lap at 182.8km/113.6mph. The car consumed 1693 litres (372.50 gallons) of paraffin, making average fuel consumption a mere 6.9mpg — or 40.9l/100km. Although unclassified, the Rover-brm would’ve finished eighth overall if it had been petrol powered.
Back at Solihull, the car was prepared to take part at the British Grand Prix, due to be held on June 22 at Silverstone. On that historical day, Trevor Collins was present as JET 1, T3, T4 and the Rover-brm appeared on track before the main event. A mock race was set up with Spen King at the wheel of JET 1, Richie Ginther in T3, Tony Worster in T4 and Graham Hill in the Rover-brm.
