The 1986 Luce was large and luxurious on the HC platform, now with the 13B turbo engine as one of many engine options. It was still exported as the 929, and differed from the (continued) Cosmo. In the 1990s Mazda sold the body stampings to Kia where it was reproduced until the early first decade of the 21st century in piston form and sold in Korea only as the Kia Potentia.
This generation vehicle was sold in North America after the arrival of the Acura Legend in 1988 in sedan bodystyle only; the hardtop was not available, nor were the rotary engines. Actor James Garner was used as a spokesman introducing the 929 to North America
1991 was the last year of the Luce nameplate. The Eunos Cosmo was already on sale (JC), and the HD platform spawned the Mazda Sentia (now exported as the 929), and the Efini MS-9, making 1991 the last year for a 4-door rotary powered sedan prior to the RX-8.
The 929 was updated in 1986 (1987 in some markets) with the HC platform and a 3.0 Liter V6 engine. The car was produced through 1991, again lagging behind its Japan-market twin, the Mazda Luce, by one year. The 929 began U.S. and Canadian sales in 1988; although predominantly available as a 3.0 Liter V6, there were a rare few that made it to the North American market as a 4-cylinder 2.2 F2 in a RWD configuration. After 1990, when Chrysler dropped its Fifth Avenue and Dodge Diplomat (both of which had 318-cubic-inch V8 engines) it would exclusively rival the Toyota Cressida until 1992 when Toyota stopped Cressida exports to concentrate on the new Lexus brand.
The HC platform came out in two variations during its five year span that had identical engines and interior but with two distinct body shapes; a pillared four-door sedan as well as a slightly larger pillarless four-door hardtop. While the pillared model was common in all countries that allowed the importation of the 929 (including the US and Canada), the pillarless model was predominantly seen in the Asian and Australian markets.
The Luce Royal Classic (and lesser-spec Limited) was more expensive than its 929 counterpart, featuring greater technical innovation — both were pillarless hardtops. The Royal Classic was factory fitted with a turbocharged 13B Rotary or 2.0 Litre V6 engines, electric leather seats, digital speedometer, a cool-box for canned beverages, prominent emblems, electronically adjustable suspension and power options throughout. In order to satisfy Japanese regulations concerning exterior dimensions and engine displacement, this generation vehicle was built in two versions; the 3.0 V6 was installed in the longer and wider hardtop bodystyle, and the smaller engines, including the rotary engine, were installed in the shorter and narrower sedan bodystyle.
The Canadian 929 came with a 'Winter Package' option and included heated seats, a higher grade alternator, winter tires and non-recessed windshield wipers. A five-speed manual gearbox was an option, but most North American 929s were two-mode ('power' and 'economy') electronic 4-speed automatics. Top speed was 121 mph (195 km/h). A 0-60 mph time of 9.2 seconds was recorded using the manual gearbox; the automatics were somewhat slower at 10 seconds.
The first 3.0-litre V6 engine seen in the 1986–1989 929 was a Single Overhead Cam type with 18 valves. When Mazda released the higher-spec 929S model for the 1990–1991 period, the engine was upgraded to a Double Overhead Cam type with 24 valves, slightly increasing fuel economy, performance and reliability. Also in the revised edition came the presence of an anti-lock braking system, ventilated rear disc brakes and a few inconspicuous changes to the exterior. The standard 18-valve SOHC remained in the base model 929.

When the HC series Luce was replaced with the Mazda Sentia, it continued to be manufactured in South Korea as the Kia Potentia. That vehicle was in production from 1992 until 2001 using the 2.0 liter 4-cylinder Mazda FE-DOHC engine, which was the same as the first generation Kia Sportage's gasoline version, 2.2 liter 4-cylinder and a 3.0 liter V6. The Potentia was replaced by the Kia Enterprise, which was based on the Mazda Sentia and introduced in 1997 after the Sentia was cancelled.
