FactThe HB Cosmo is one of only two cars in history sold with a buyer's choice of gasoline, diesel, or rotary power — and it was the last Cosmo ever exported.
The third-generation Cosmo of September 1981, sharing the HB chassis with its twin the Luce and sold overseas (without the rotary) as the Mazda 929. A coupé (two-door hardtop), frameless-window four-door hardtop and formal pillared saloon; the coupé was Japan-only, and the cars were sold at Mazda Auto (renamed Eunos in 1991). Drag coefficient 0.32, the lowest in the world at its introduction. The page calls it one of only two cars ever to offer a choice of petrol and diesel piston engines or rotaries. Rotaries were the 12A-6PI (six-port induction), the 12A Turbo (the first fuel-injected rotary, late 1982, officially the fastest production car in Japan until the FJ20ET R30 Skyline RS) and, from 1983–84, the 13B-RESI with a four-speed JATCO automatic; a 1983 facelift brought the 13B-SI and fixed headlights on the four-door hardtop, and after the 1986 FC RX-7 the coupé took its retractable headlights. Piston engines were the 1.8 L VC, 2.0 L MA and FE (with an FET turbo) and a 2.2 L S2 diesel. The Luce and Cosmo saloons ended in 1986 and both hardtops trickled on to 1989. The Australian 929 FE-Turbo EGI Luxury (1986–May 1987) used the 2.0 L FET at 136 PS.

Owning one
We don’t estimate running costs for a car like this. What it costs depends on its condition, its specialist and how it is driven, and an average would mislead.

Years before anyone had a GPS in their pocket, this Eunos Cosmo had one built into the dash — it was the first production car anywhere with built-in satellite navigation.

This oddly-named "Cosmo AP" (Anti-Pollution) was no flop: over 55,000 sold in Japan in its first year alone, and Mazda credits it with saving the company from financial disaster.
Rivals
Same body, same money, other badges — tap any card to flip.
The Celica XX, Japan's name for the A60 Supra, introduced the world's first in-car navigation computer.
The CTR Anniversary looks like a 911 but Ruf built its carbon monocoque from scratch, no Porsche body underneath.
The 228's coupe styling hides a sedan underneath: Maserati stretched it onto the longer four-door Biturbo chassis to make room for its biggest V6, which is literally where the name comes from — 2-door, 2.8 litre.
Switching to fuel injection let this V8 finally shed its trademark bonnet bulge — and only 405 of these flat-hooded Series 5 cars were built before the whole model retired in 1989.
Japanese buyers got a secret weapon in their MX-6 — the JDM-only KL-ZE V6 made about 40 more horsepower than the engine sold in the exact same car in North America.
An American tuner, Callaway Cars, built twin-turbo conversions of the GTV6 that boosted its V6 by fifty percent to 230 hp — turning Alfa's grand tourer into something far quicker than the factory ever intended.
