Daimler SP250 Dart: The British Sports Car That Shocked the World
Share
The Daimler SP250 Dart is one of those cars that rewards the brave. Unconventional, ferociously quick for its era, and wearing styling that divided opinion like no other British car of its generation, it remains one of the most intriguing sports cars to emerge from post-war Britain. Few cars have been so misunderstood, and fewer still have aged quite so well.
It was fast, characterful, and powered by one of the finest V8 engines ever fitted to a production British car. That counts for a great deal.
Origins and History
The SP250 was born from genuine crisis. By the late 1950s, Daimler was in serious financial difficulty. The company needed a bold move to attract attention, particularly in the lucrative American export market, where sports cars from Jaguar and Triumph were cleaning up. Chief engineer Edward Turner, the motorcycle genius behind the legendary Triumph Speed Twin, led the project.
Turner designed a completely new 2.5-litre V8 engine from scratch, then commissioned a lightweight fibreglass body to wrap around it. The car debuted at the 1959 New York Motor Show, where Daimler hoped the American audience would fall for its exotic specification. The original name, Dart, was dropped when Dodge's lawyers pointed out they had registered it first. Daimler renamed it the SP250, though almost everyone still calls it the Dart.
Within a year, Jaguar had acquired Daimler. Sir William Lyons was never a fan of the SP250 and production ended in 1964 after just 2,650 cars. It was a short life, but an eventful one.
The Design
Be honest: the SP250 is not conventionally pretty. The styling, penned with one eye firmly on American tastes, features bulging wheel arches, a gaping open mouth at the front, and fins that sweep rearward with genuine commitment. On a dark night, those fins mean business.
The fibreglass body was genuinely innovative for a British manufacturer at the time, keeping weight down and allowing complex curves that would have been expensive in steel. The open cockpit, fold-flat windscreen, and chrome detailing give it the look of something born to run on wide American boulevards rather than English country lanes. Yet somehow it works. There is real presence here, and a character entirely its own.
Early cars suffered from a flexible body structure, leading to doors that popped open under hard cornering. Daimler addressed this with reinforced B and C specification cars, which added a steel strengthening frame. Always check which specification you are buying.
Performance and Driving
Whatever you think of the styling, Turner's V8 engine is beyond reproach. The 2,548cc unit produced 140 bhp in standard trim, enough to push the lightweight SP250 to 60 mph in under nine seconds and on to a top speed of 120 mph. In 1959, those numbers were genuinely startling. The contemporary Jaguar XK150 was barely quicker, and it had a much larger engine.
The V8 is the star of the driving experience. It pulls cleanly from low revs, spins freely to the red line, and sounds absolutely magnificent through the twin exhausts. The four-speed manual gearbox is direct and satisfying to use. Handling is communicative if not quite in the class of a Lotus or Triumph TR of the period, with the front disc brakes, standard equipment from the start, giving the SP250 a genuine advantage over many competitors.
Drive one today and the combination of that engine note and the open-air experience is deeply addictive. This is a car that rewards commitment.
Racing Pedigree
The SP250 found an unexpected second life on British racetracks. The Metropolitan Police ran a fleet of them as pursuit vehicles, a fact that brings a quiet smile to anyone who imagines chasing Austin A40s in a fibreglass-bodied Daimler V8. They were chosen for good reason: few production cars of the early 1960s could match the SP250 for outright pace on British roads.
In competition, the SP250 proved quick and reliable. Works-prepared cars competed at Le Mans in 1961 and 1962, finishing creditably in the GT class. At club level, the cars were raced extensively throughout the 1960s, and a healthy historic racing scene keeps them in competition to this day. Their combination of power, light weight, and disc brakes made them genuinely competitive, and the best examples today are still formidable in period events.
The production run of just 2,650 cars means every surviving example has real historical significance.
Buying a Daimler SP250 Dart Today
Values for SP250s have risen steadily as the classic car market has woken up to their significance. A good, honest driving example will set you back somewhere between £30,000 and £50,000. Fully restored, concours-quality cars command £70,000 and above, with the rarest and best-documented examples occasionally exceeding that.
The fibreglass body is both the SP250's greatest asset and its most important area of concern. Look carefully for cracks around door apertures, the screen surround, and wheel arches. Repairing fibreglass properly is a specialist job and shortcuts are common. Always check the steel chassis rails for corrosion, particularly around the outriggers and jacking points.
The V8 engine is generally robust if properly maintained, but oil leaks are endemic. Budget for a full engine reseal if the history is unclear. The gearbox and differential are both strong, though finding reconditioned parts requires specialist knowledge. Join the Daimler and Lanchester Owners Club before buying: their technical knowledge and access to spares are invaluable, and the community is genuinely welcoming to new owners.
