Triumph 2.5 PI Mk I

In 1968 Triumph added a new high performance model to the already successful Triumph 2000 Saloon and Estate range, the fuel injected 2.5 PI (Petrol Injection) Saloon. The new Saloon made use of the same bodyshell as used for the standard 2000 Saloon, only sportier wheel trims, badges and minor trim details distinguished the new top of the range model.

The 2.5 PI used a 132bhp version of the sic cylinder engine used in the Triumph TR5 sports. This powerful engine could be mated to optional manual overdrive or automatic transmission depending on the buyers preference. Unfortunately the early Lucas fuel injection caused problems for some owners and gained the PI an unfair reputation for unreliability (which has been eliminated by the Triumph specialist network and is no longer a major concern).  Practical Classics December 2007 - Featuring Buyers Guide Triumph 2000,2500 And 2.5 (1963-1977).  Click Here to view in our shop.
