The Triumph TR5 is a sports car built by the Triumph Motor Company in Coventry, England, between August 1967 and September 1968.
Visually similar to the TR4 (also styled by Michelotti), the TR5 roadster sported Triumph's much more powerful 2.5-litre straight-6, fitted with Lucas mechanical fuel-injection and producing 150 bhp. Price pressures and tighter emissions standards in the U.S. resulted in a much less powerful carburetted version, the TR250, being sold on the North American market.
At the time, fuel injection was uncommon in road cars. Triumph claimed in their sales brochure that it was the "First British production sports car with petrol injection".
