The Healey by Caton design has been directed by Darryl Scriven, who explains: “Donald Healey got so much right when he designed the car originally. We wanted to pay homage to the original vehicle while making it more comfortable to live with, more fun to drive and even more dynamic and beautiful to look at.”
For the most part, though, Caton has refined, rather than added to the Healey's body. The rear bumpers are gone, as are the external boot hinges, replaced with new internal hinges running on modern gas struts. The boot handle is deleted too, and the lid is now opened by an internal release mechanism, run by a new, modern Caton key.
The car’s beating heart is a 185bhp 195ft/lbs of torque 2954cc four-cylinder engine, endowed with performance to take the car well beyond the 100mph top speed it was named for. Based on an original Austin-Healey block, the engine is completely stripped down, fully lightened, balanced and then refurbished to zero miles. It is further enhanced with a full steel crank shaft, upgraded bearing shells, high compression pistons, a race camshaft with more aggressive lobes and roller rockers. Larger Twin H8 carburettors and gas flow inlets provide excellent throttle response. A race side-exit exhaust system adds further to the car’s considerable aural appeal.
The engine, and most of the car's mechanical components, are the work of the world’s leading Healey specialists J.M.E. Healeys (J.M.E.), who have strong historical links with the original Healey company. Jonathan Everard, who founded J.M.E., and his father Harold, worked for the Donald Healey Motor Company in Warwick. Today, the company is run by Jonathan’s sons, Chris and Dan and is based in The Cape Works in Warwick, the original home of the Healey company.
