The Daimler 2.5-V8 (or 2½ litre V8) was a four-door saloon produced in Coventry, England by Daimler. Launched late in 1962, it was essentially a rebadged Jaguar Mark 2, but fitted with Daimler's 2.5 litre V8 engine; aside from the engine, fluted (furrowed brow) grille and rear number plate surround, badges, drive-train and some interior details (such as a split-bench front seat and a black enamel steering wheel) the Daimler 2.5-V8 was otherwise indistinguishable from the Jaguar Mark 2.

The 2.5-V8 was the first Jaguar designed car to have the Daimler badge. The Daimler V8 engine was more compact and therefore lighter than the six cylinder engine used in the Jaguar Mark 2, and weighed approximately 50 kg ("1 cwt") less. Spring and damper settings were revised accordingly to suit the altered weight distribution. Three years after its launch, a Daimler 2 ½-litre saloon with automatic transmission tested by the Britains Autocar magazine in May 1966 had a top speed of 112 mph (180 km/h) and could accelerate from 0-60 mph (97 km/h) in 13.6 seconds. An overall fuel consumption of 19.0 miles per imperial gallon (14.9 L/100 km; 15.8 mpg-US) was achieved. The test car was priced in the UK at £1,647 including taxes: Rover's 3 litre with automatic transmission was retailing for £1,770. At the end of 1965, the final drive ratio had been changed from 4.55:1 to 4.27:1, addressing complaints that the car as launched in 1963 had needed to exceed its recommended rev limit in order to reach its top speed, with a corresponding penalty in fuel consumption and engine noise and wear. The testers found the car refined and well equipped with efficient, if rather heavy, brakes. The engine and transmission were felt to be well matched. The car was quiet and smooth but short on low speed torque.
