The Daimler Dart was launched at the 1959 New York Motor Show, and its greatest success was in the American market. It had a fibreglass body, four wheel Girling disc brakes, and a 2.5 litre Hemi-head V8 designed by Edward Turner. They were soon forced to drop the Dart name when threatened with legal action by Chrysler’s Dodge division, the car was then renamed the Daimler SP250.^[1]

[edit] Models

The original A-spec version could do 120 mph, but the chassis, a “14-gauge ladder frame with cruciform bracing”, flexed so much that doors came open, marring its reputation.^[2]

Jaguar bought Daimler in 1960, and were immediately concerned about the chassis flex. They brought out the B-spec version with extra outriggers on the chassis and a strengthening hoop between the A posts. There were also other detail improvements, including an adjustable steering column.^[1]

There was a C-spec version introduced in 1963 with some additional luxuries as standard equipment.

2645 were produced.
