Grand Prix racer

In the inaugural World Championship of Drivers, Walker was present at the very first race, the RAC British Grand Prix at Silverstone. In fact, he was one of the first to enter the event, in his own ERA E-type. After qualifying tenth, he shared the race driving duties with Tony Rolt, pitting after just two laps to hand the car over. Unfortunately, the pace show in qualifying wasn't matched by its endurance, was Rolt retiring the car on the fifth lap due to gearbox problems. Walker's inaugural Formula One season ended there, as he did not contest another Grand Prix that season.^[2][4]

A month later his victory at Circuit de la Sarthe, he finished seventh in the RAC British Grand Prix in a supercharged 1.5-litre V16 BRM Type 15, with his teammate Reg Parnell in fifth. Both drivers legs were so badly burnt by heat from the engines and exhaust systems that even walking was painful. Gregor Grant reported: "Parnell and Walker saved the day for British motor racing. Their heroism in sticking to their task whilst suffering from agonising burns will enable the BRM designers to go ahead and modify the cars to make them completely raceworthy." Sadly, Walker did not race the BRM again.^[2][3][5]

After four years away, he returned to Formula One, racing twice. The first was aboard Stirling Moss's Maserati 250F, where he retired from the Grote Prijs van Nederland, with mechanical issues. For the next race of the season, RAC British Grand Prix, at Aintree, he shared a works Connaught Type B with Rolt. In what turned to be his last Grand Prix, the car was retired with a failed throttle after just 19 of the 90 laps.^[6][7]

Sports Car Ace

Walker performances of the hills brought him to the attention of Lofty England, the manager of Jaguar's sports car racing team, rewarded him with a drive in a Jaguar XK120 in this newly launched car's first race at Silverstone in 1949. Walker finished second, but won at same event 12 months later, in an alloy-bodied works-prepared XK120.^[5]

After the success of XK120, they developed an endurance racing version, the XK120C, or C-Type and need a driver. Walker was approached and with it, Jaguar embarked on their first racing program aimed at winning the 24 Heures du Mans outright. On its first attempt, just six weeks after completion, Walker achieved the victory for which he is best remembered, when he and co-driver, Whitehead won the 1951 race. Of the three entered, they filled the top three positions after four hours. However, after just 50 laps, only Walker's remained in the race. The victory providing the Coventry marque with much publicity and acclaim.^[2][3][4][8]

Still nursing his burns from the British Grand Prix, Walker dismissed them as little more than "a bit of a nuisance", he arrived at Dundrod to race a C-Type in the RAC Tourist Trophy. Jaguar cleaned up, taking all three places in the podium. As for Walker, he finished in a dutiful second behind Moss.^[5]

In the 1953 race, he shared his works C-Type with Stirling Moss, and the pair led in the early stages until the engine problems intervened. Moss pitted on lap 20, and the mechanics set to work. The problem was only solved after a second stop, when the mechanics changed a blocked fuel filter. Moss and Walker would finish second, four laps down on their winning teammates, Rolt and Duncan Hamilton. This would be the closest Walker would ever get to a second victory at Le Mans.^[9][5]

Walker was paired again with Moss for the Goodwood Nine-Hour and they led comfortably for the first eight hours, until the car retired. Next up was the RAC Tourist Trophy, where Walker would break the lap record, but again hit mechanic troubles and Moss managed to bring the car home in third.^[5]

Although he remained with Jaguar for 1954, the season wasn't as successful, despite teaming with Moss for Le Mans in a Jaguar D-Type, when they retired in the 12th hour with brake problems. At the end of the season, England asked Walker to make himself available for pre-season testing, ahead of the 1955 season. Walker failed to respond and joined Aston Martin. This proved not to be a good move, as Jaguar's great hat-trick of Le Mans victories was about to begin. Some consolation to Walker, was his fine victory in the Goodwood Nine-hour, a race in which shared an Aston Martin DB3S with Dennis Poore.^[5]

He largely retired from racing after crashing a DB3S at Le Mans in 1956. He made a mistake in the 16th hour of the race, whilst running strongly. He suffered what would basically turn into a career-ending accident. The car skidded on the wet track near the Dunlop Bridge and hit the wall – ultimately sliding upside down on the track.^{[1][2][3][10][11]}

Walker did test and race again in 1957. In the spring, he tested for Rob Walker Racing Team, in their Connaught Type B at Goodwood, and subsequently drove the car in a one-off race, the Gran Premio di Siracusa the following season. He was classified in eighth place despite spinning and stalling the car late on.^[12][13]
