Triumph TR5 / TR250

After the body change (1961) and the chassis change (1965) came the engine change of 1967. Except in detail, TR5s looked like TR4As, but there was a fuel injected 150bhp/2498cc six cylinder engine up front. Much more performance than any previous TR (120mph, flat out). None of these cars went to North America when new. Strictly a one season wonder as the re-styled TR6 took over before the end of 1968. 2947 cars built between 1967 and 1968.

The TR5 couldn't be sold in North America because of the USA's new exhaust emission regulations. Instead there was the TR250, exported to North America and Canada only, with twin Stromberg carburetted 104bhp/2498cc six cylinder engine, and transverse speed stripe across the nose for recognition purposes. Just as fast as the old TR4A but much smoother and more civilised. 8484 card built in 1967 and 1968.
