Triumph does not build many cars like the Triumph 1500: a Four-door saloon with 1493 cc OHV I4, built from 1970 to 1976 as the oil crises and the first emissions rules rewired the industry. Its designer of record is Giovanni Michelotti.
Where it came from
The Triumph 1500 is a small front-wheel drive car that was produced by Triumph Motor Company division of British Leyland from 1970 to 1973. In 1973 it was revised as the Triumph 1500TC becoming rear-wheel drive. Production ended in 1976, by which time it had been replaced by the Triumph Dolomite.
Under the skin
Under the skin sits 1493 cc OHV I4. Kerb weight is 2093 lb. The gearbox is a 4-speed manual / FWD on 1500 / RWD on 1500TC. The wheelbase is 97 in. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
In context
Where it sits in Triumph's history is not in doubt: the Triumph 1300 came before it; the Triumph Dolomite followed it; it was built at Canley, Coventry, United Kingdom. On a showroom list of its day it stood against the Chevrolet Impala, the Suzuki Jimny, the American Motors Corporation AMC Gremlin. Nearby in the Triumph catalogue sit the Triumph SD2 and the Triumph Renown.
The money
MotorJury scores cars on the United States complaint and recall record, and the Triumph 1500 has none: too old, too rare, or never sold there. Its value today is a collector's question, decided by provenance and condition rather than by a class average.
