The 18hp is a car initially sold by the British automaker Lea-Francis from 1949 to 1954. It was not a very successful model, and only 80 were made. Very few examples are known to exist today.

The 18hp is stylistically identical to the 14hp, but features a more powerful and bulky 2496cc four-cylinder engine capable of generating 90 to 95 bhp of output. It was sold as a saloon and sports car. The car itself is rather heavy, and weighs roughly 1372 kg.
