Asteam-powered car seems anachronistic today, but when identical twins F. E. and F. O. Stanley began making them in 1897, it was the most proven motive technology around. Early Stanley cars featured a tubular chassis frame with a light, wooden buggy body. The vertical boiler, under the double seat, at first featured copper fire tubes, with a vapourizing gasoline burner underneath. Drive went from the engine crankshaft to a rear-mounted differential, by chain. The design was a success and soon the company was bought by a business consortium for $250,000.
But the new owners lacked the Stanleys' touch, and the brothers bought their old factory back in 1901 for just $20,000. They immediately put an improved model, the definitive Stanley Steamer, into production. It featured a new, horizontally mounted engine, geared direct to the back axle. And the boiler was later shifted to the front. The Steamer's finest hour came in 1906, when Fred Marriott drove a special one across Daytona Beach, Florida, at 127.659mph (205.447kph)-still the longest-standing unbroken record for steam-powered cars, over a century.
