Louis Rosier, French champion driver, had a great deal of success in the immediate post war years with the 4.5 litre single seater Lago-Talbot.
He saw in the characteristics of this uncomplicated, rugged car, the makings of a Le Mans winner. He persuaded Antonio Lago to lay down a batch of 4 chassis for the 1950 race , designated T26 GS.
Only one chassis was ready for Le Mans, to be driven by Rosier and his son, Jean-Louis. After an early challenge from Raymond Sommer, Rosier took the lead , posting the first ever 100mph lap, and continued driving through the night, until at 5am he pitted with a broken rocker shaft. This mishap put the car down into 3rd place, and after 2 laps, whilst Rosier Junior was finally allowed his turn at the wheel, Louis leapt in again, catching the two cars ahead of him by 9am, and rolling off the remaining laps , to win by 3 laps at 89.71 mph
