The S type was quickly branded the Hyper by Lea-Francis and is how it has been commonly referred to since. After experiements with a variety of superchargers, Lea-Francis adopted the Cozette for use in its competition cars, from which the S type evolved, to become the first supercharged British production car.

The S type used the same basic chassis design as the O and P types, but with the Meadows 4ED engine set further back to give space for the Cozette supercharger behind the distinctive sloping radiator. It also had servo-assisted brakes.

Initially it was available with four-seater tourer and even saloon bodies, and later came a Weymann coupé.

The car had many successes in racing, both in the hands of private owners and the factory, most notably winning the 1928 Ards TT, after which a skimpy two-seater like the competition cars was marketed, called the “TT Replica”.

In standard form, with a No.8 Cozette supercharger and relatively standard Meadows 4ED engine, the S type was capable of 85mph. The competition cars, with a No.9 Cozette, roller bearing crank-shaft and re-worked Meadows 4ED were capable of well over 100mph - one is known to have lapped Brooklands at 112.8 mph.

About 180 S types were produced of which as many as 41 may have survived in one form or another.
