1983, certain Canadian models received the same B23F engines fitted to the US models (49-state emission regulations) and the B21FT (conformed to the California emission regulations). In 1985, the B21A was dropped, and the new B230F engine was introduced for use in all non-turbo 240s in both markets. Had a 9.8:1 compression ratio, instead of 10.3:1 for the earlier B23F in automatic and early 1983 manual form, or 9.5:1 for late 1983 through 1984 manual form. Had the higher horsepower number of the automatic B23F (114 SAE net HP) and the higher torque number of the low compression manual B23F (136 foot-pounds of torque). Fuel system was, again, LH-Jetronic, but updated to 2.2, which used a different mass airflow sensor and computers. It also was redesigned to be lower-friction than the earlier B21 and B23 engines with lighter weight connecting rods and pistons that had a shorter skirt. In 1989, the B230F received the Bosch LH-Jetronic version 2.4 fuel injection system, which added OBD-1 onboard diagnostics. The ignition system was similarly updated from the Volvo/Chrysler ignition system that used a Bosch coil and distributor to the Bosch EZK-116K system. Some manual 1990-93 B230F engines used the LH-Jetronic 3.1 system, which used a heated film mass airflow sensor, instead of the usual hot wire sensor. Six-cylinder PRV The 260 models had a completely new 90-degree V6 B27E engine, sometimes called the "Douvrin". This engine was developed jointly by Peugeot, Renault and Volvo in collaboration, and is therefore generally known as the "PRV engine". This engine was unusual at the time, being composed of many small parts in a modular design (as opposed to a monolithic engine block and head). The B27E engine has a displacement of 2,664 cc, an aluminium alloy block, and wet cylinder liners. This engine produces for both the 264DL and 264GL. In fuel-injected form, the B27F was introduced to the US in the 1976 260 series. The two-door 262 DL and GL sedans, the 264DL saloon (sedan) and the new 265DL estate (station wagon) were offered outside North America with the B27A engine. Almost identical to the fuel-injected V6 B27E engine, it has an SU carburettor instead of fuel injection, and therefore it produces a lower output of . The PRV engine (B27E in 1980, B28E 1981–1984) was also used in 244/245 GLT6 on several markets as an option until 1984. Volvo increased engine displacement to 2.8
