The Holden HT series is a range of automobiles which was produced by General Motors Holden’s in Australia between 1969 and 1970.
Holden HT Belmont, Kingswood and Premier models were introduced in May 1969, replacing their Holden HK series equivalents which had been in production since 1968. HT Brougham and Monaro models followed in June 1969. Noticeable changes from the HK series included new grilles, new taillights, flatter rear flanks and a wider back window. Other changes included increased track width, revised suspension, a new instrument panel and synchromesh on all forward gears on manual gearbox models.
161 cubic inch (2.6 litre) and 186 cubic inch (3.0 litre) six cylinder engines were carried over from the HK range. Australian manufactured 253 cubic inch (4.2 litre) and 308 cubic inch (5.0 litre) V8 engines were new, replacing the imported 307 cubic inch (5.0 litre) V8. Initially the 308 was only fitted to the Brougham and existing stocks of the imported 307 were used in other models. Once these supplies were exhausted, the 308 V8 was made available as an option across the HT range. The 327 cubic inch (5.3 litre) Chevrolet V8 that had powered the HK Monaro GTS 327 was replaced by a 350 cubic inch (5.8 litre) Chevrolet V8 in the newly introduced HT Monaro GTS 350 model. Three–speed manual, four–speed manual and two–speed “Powerglide” automatic transmissions were offered.
The HT range was replaced by the Holden HG series in July 1970, production having totaled 183,402 units.
