Presidential Speed King – Renault 40CV NM Montlhéry Coupé

The Renault 40CV was launched in 1911 powered by a 7.6 litre / 460 cui straight six and could be ordered with either an 3.6m / 11′ 9″ or 3.9m / 12′ 9″ chassis.

With the introduction of the 40CV Type HF in August 1920 the engine was upgraded to a 9.1-litre 9,120 cc / 557 cui straight six.

From 1920 to 1928 the Renault 40CV replaced the Panhard 20CV as the French Presidential vehicle of choice.

François Repusseau drove a 40CV to victory in the 1925 Monte Carlo Rally and the following year a vehicle similar to today’s featured 40CV MN was modified and fitted with a single seat Coupé body and taken to the Montlhéry Oval outside Paris for a record braking 24 hour run.

Facilitated by a pit crew of 14 who could complete a pit stop including changing all four tyres in 50 seconds every hour and a team of unnamed drivers the 40CV set a new 50 mile average speed record of 190.013 kmh / 118 mph and a 24 hour record of 173.649 kmh / 107.9 mph, by comparison the fastest average speed on the road course at Le Mans for the 24 hours race in 1926 was just 106.35 kph / 66 mph set by Robert Bloch and André Rossignol in their 3.4 litre / 207 cui Lorraine-Dietrich B3-6.
