The straight-six engine, which had been used for many years, was upgraded to an all new V6-design, called the VG series engine which made its debut in the Cedric/Gloria. This was the first, mass production V6 engine built in Japan. The VG range uses fuel injection rather than carburetors for fuel delivery. The VG20ET was turbocharged, for better performance while staying within the Japanese tax parameters for a compact car. The twin-carbureted four-cylinder CA20S engine was fitted to the lowest-spec versions (standard, De Luxe). This four-cylinder was also available in a version built to run on LPG fuel, meant to be used for taxi service. From February 1984 there was also a six-cylinder L20P, which also ran on LPG. In June 1984 the powerful 3-litre VG30ET turbo V6 was introduced.
