Sir Jackie Stewart won a total of six Grands Prix in 1969, five in the MS-80 and one in the Matra MS-10 (‘precursor’ to the MS-80). He enjoyed a prestigious victory at Silverstone with an epic battle against Jochen Rindt. And then at the Italian Grand Prix at Monza, Jackie led for many laps but only beat Rindt’s Lotus 49B to the flag by less than a car’s length; that victory, however, ensured his first world drivers’ championship, with three races of the season to spare. he Matra MS80 was the fourth Formula One car produced by Matra (following the MS9, MS10 and MS11). The Ford Cosworth DFV-powered car (engine 3000 cc, estimated at around 420 bhp (313 kW)) took Jackie Stewart to the Formula One World Championship title in 1969. The car, designed under the direction of Gérard Ducarouge and Bernard Boyer, was built at Matra's Formula One base at Vélizy-Villacoublay in the southwestern suburbs of Paris, though the final completion with the Cosworth engine was done in the Tyrrell workshop of East Horsley near Ripley, UK. A major change from the MS10 was the location of the fuel cell, which was moved from behind the driver and placed in sidepods by the driver's hips, giving the car a slight 'Coke bottle' appearance. The rocker-arm front suspension was replaced by outboard springs, with a parallel link set up on the rear suspension. Apart from Ferrari cars, the Matra MS80 is the only non-British built car to win the Formula One World Constructors' Championship (the French constructor Renault, the Austrian constructor Red Bull and the German constructor Mercedes built their winning cars in the UK). Although officially a Matra, it was run by the non-works Matra International team of Ken Tyrrell. The MS80 was one of the first F1 racing cars to be designed with "wings" for downforce to increase high-speed tyre grip. These were originally introduced into F1 in 1968.
