The Triumph TR250 Sports activities Automotive

A overview of The Triumph TR250 Sports activities Automotive, protecting improvement, vital options, and technical information of this the twelfth mannequin within the TR vary.On this Article, I provide a nostalgic take a look at the Triumph TR250, considered one of an elite group of traditional vehicles, which was manufactured in the course of the interval 1967 to 1968.Initially, Triumph had deliberate to interchange the TR4A with the TR6 in mid 1967. Nevertheless, in response to legend, the TR6’s designers, Karmann, offered Triumph with the tooling specs, incorrectly, in metric items.This error set again the launch of the TR6. Consequently, as a cease hole measure lasting a yr, a design for the TR250 was rapidly put in place to fulfill the US market.In 1967, the TR250 was launched concurrently the launch of the TR5.Externally, aside from the grille, there was nearly no distinction between the 2, nor with the TR4A, the automotive they have been changing.

Nevertheless, a notable styling function was a transverse pace stripe throughout the bonnet of the TR250, which additionally displayed a particular “TR250” badge.There was the same badge on the rear wings, and one saying “Triumph TR250” on the boot.The TR5 was designed for the UK and European markets, and none have been exported to the US.However, the TR250 was aimed particularly on the US market, and was solely out there as a LHD model.The Lucas gasoline injection system on the TR5 didn’t meet the strict US emission management rules. Since any modifications to this method might become unduly costly, it was determined to search for another.The answer was to make use of the identical 2.5 litre, straight 6-cylinder engine because the TR5, however as an alternative of gasoline injection, to include two Stromberg carburettors growing 104 bhp, paradoxically the identical as that produced from the TR4A.This engine was a direct descendent from that used within the Triumph 2000 saloon automotive, which developed 90 bhp, however bored out to 2.5 litres and fitted with a modified camshaft.The end result was an influence enhance of 60 bhp for the TR5, and 14 bhp for the TR250.Nevertheless, the substitution of carburettors instead of gasoline injection had an antagonistic impact on efficiency, with energy output, high pace, and Zero-60 occasions all struggling.Alternatively, in contrast with the TR4A, the torque elevated from 128 to 152 lb-ft, which made even the carburetted model a really clean engine.Additional, with its Zero-60 in round 10 secs, it was in the identical league because the Austin Healey 3000.On the draw back, even with impartial suspension, the nostril would stand up on acceleration and dive on breaking, and the journey was considerably bouncy.Identical to the TR5:

It was out there as a tough high model, with a removable Surrey Prime
It had impartial suspension all spherical
It had energy assisted disc brakes on the entrance with drums on the rear
It had a 4 pace gearbox, with overdrive and wire wheels as non-obligatory extrasThe TR250 was a direct success within the US, and much outsold the TR5.This marked the tip of the Triumph TR250Maybe this stroll down reminiscence lane may need answered, or not less than make clear, a potential query:Which TR Sports activities Automotive is Your FavouriteHowever, ought to this query nonetheless stay unanswered, I will probably be reviewing, in some element, in future articles inside this web site, your entire vary of TR sports activities vehicles which have been featured within the memorable period spanning 1952 to 1981.I hope you be a part of me in my nostalgic travels “down sports car memory lane”.
