Thebasic TR2/3 shape was in production from early 1953 to 1961.
While the chassis, center section, doors and running gear of the TR6 were essentially the same as the TR4A/TR250/TR5, the body was re-designed by Karmann of West Germany, recognized for VW, Porsche, and BMW designs. Under the hood, the old four cylinder engine from the earlier TRs were replaced with a six.

Its successor the TR4/5 ranfor a further eight years from 1961 to 1969. To the casual observer the TR6 looked like acompletely new car. However, looks can be deceiving.Mechanically the TR6 was identical to the TR5 on which it was based.
Karmann Coachbuildersof Germany carried out a skillful restyling exercise that built a completely differentlooking nose and tail onto the existing middle section of the body. The transformation wasamazing. The TR5 looked the archetypal British sports car, while its TR6 successor lookeda refined and expensive continental machine.
In the case of the optional hardtop thisreturned to a one piece unit without the Targa-style lift-off center section.The TR6 proved to be the MOST POPULAR VERSION of all and during its seven year life itnotched up sales of over 94,000 units. North American specification cars differed in thatthey continued to use carburetors in place of the fuel injection used elsewhere. The TR6proved to be both more economical and faster in acceleration than the rare TR5 on which itwas so largely based.The TR6 was introducedin January, 1969, using similar chassis and running gear components to those used in theTR5/TR250. However, the body work, while retaining some elements of the TR5/TR250 design,was externally restyled by Karmann. Apart from smoothing the lines of the car, the designchanges also gave the car more boot space.
A front anti-roll bar now formed part of thespecification and wider wheels were also fitted making the car look low, lean and veryfast - which, of course, it was, courtesy of the TR5/TR250 smooth 6-cylinder inline 2498ccengine. The powerfulsix-cylinder engine is a reliable until, whether with UK-market petrol injection (150bhp)or US-market carbureted (104 bhp) fuel delivery. The UK petrol intected version wasde-rated to 125 bhp in 1973 by by camshaft alterations and revised fuel injectionmetering. These changes made the TR6 smoother and more flexible. The TR6 was modified inseveral respects during its production run and the components affected include the gearbox(ratios) and the optional overdrive (type). The trim was also altered and an air dam wasfitted below the bumper from 1973.
A useful option on the TR6 was the one piece detachablesteel HARDTOP which easily converted the car to a neat sports coupe. The car retained theappeal of traditional British sports models but had the additional, exciting element ofbeing faster than many would-be rivals. This combination of tradition and powerhelps to explain its popularity today.The two seats arecomfortable and there is ample leg room.
The trim is functional, rather than fancy. Thefacia is neat and uncluttered, an endearing feature of most 1960s Triumphs. The woodenfacia gives an air of quality. The rear end styling of the Karmann body work is as neat asthat at the front, with flowing lines which incorporate the tail lamp units and rearbumpers. The luggage compartment is very roomy for that of a two-seater sports car and animprovement on the boot of earlier TRs. The extended body line gives greater capacity.The TR6 - theconsummation of the original TR line is an attractive, fast and very enjoyable two-seater.Its fine performance, good road holding and relative reliability, plus its sheercharacter, make it a car which is a joy to be driven by the current enthusiast!TR6 with engine managementThe only one as far as i know, FUELINJECTED TR6 in Belgium that is fitted with a modern COMMON RAIL ELECTRONIC FUEL INJECTIONSYSTEMwhere fuel and ignition are controlled by computer.
The fuel and ignitionmaps are uploaded into the computer with a laptop and can be modified at your discretion.Contrary to the Lucas system, this setup can cope easily with modern fuels.For optimal engine performance thecomputer is fed via sensors with air pressure/air temperature water temperature andthrottle position. To verify the combustion a CO meter coupled to a Lamda Sensor is fittedand you can read up the data while driving.
