in july 1978, the princess was given a revamp and renamed the princess 2. the main change was the replacement of the 1800 cc b-series engine with the new o-series engine. the new engine was offered in two sizes: 1695 cc and 1993 cc. since there was an 1800 cc tax barrier for company cars at the time, the 1700 cc o-series engine was developed to take advantage of that, whilst the 2000 cc engine was developed for the private motorists who wanted something different from the hugely popular ford cortina. the car had perhaps reached its pinnacle when the prestigious "motoring which" publication described the princess 2200hls automatic model as "an excellent car, marred only by poor reliability".
