The 1954 season began with the overall win at Sebring in Briggs’ tiny OSCA, driven by Stirling Moss and Bill Lloyd.
The plans for ‘54 included a new downsized racer, the C-6R,
that was to feature a two-stroke inverted V-12 Mercury Marine
engine. The engine never materialised, so the team turned
its attention to preparing the C-4 racers for yet another
attempt at winning the 24 Hours of Le Mans.

The team enjoyed some advance publicity at home when TIME Magazine featured the boss on the cover of the April 26 issue,
which chronicled the team’s pursuit of victory at Le Mans.
The article emphasized Briggs’ ethos of sportsmanship, bolstering
the point with quotes from the likes of Stirling Moss, who
said that Briggs “really built and drove his cars because
of his love for the sport… Briggs is a man I admire very
much – a true sportsman.”

Team Cunningham made good on the praise with another fine showing at the Sarthe. Bill Spears, still driving despite
Briggs’ earlier concerns about his vision, teamed with Sherwood
Johnston to finish third in one of the C-4R roadsters, and
Briggs and Gordon Benett took fifth in its sister car.

In an effort to test the Ferrari V-12 engine’s suitability for a future Cunningham racer, Briggs turned to his recently-purchased
Ferrari 375MM, painting it white and blue and installing a
water-cooled braking system. Further distinguishable by the
two huge air intakes on its hood, the Ferrari ran as high
as sixth for drivers John Fitch and Phil Walters until a broken
rocker arm slowed them down, the car eventually succumbing
to a failed axle bearing.

After the race, Briggs and Alfred Momo paid a visit to Enzo Ferrari to discuss the broken rocker arm. Ferrari refused
to acknowledge Briggs’ assertion that a faulty part had been
the main culprit in the Cunningham Ferrari’s failure to finish
the race. Briggs was incredulous. It was the last business
ever between the two men.
