Mazda Cosmo

There have been four generations of Mazda automobiles which went by the name of Cosmo, although they are not all particularly related. All were GT cars, with the first proving a successful launch for the Mazda Wankel engine and acting as a halo vehicle for the new Mazda brand. Later Cosmos competed in the ultra-high luxury performance market in Japan with the final JC Cosmo (1990-1995) sold as the Eunos Cosmo - Eunos was a luxury sales channel similar to Toyota's Lexus brand.

1967

The first Mazda to wear the Cosmo name (called the Cosmo Sports or 110S) was the first 2-rotor rotary engine powered car. A prototype was introduced at the 1964 Tokyo Motor Show, and 60 pre-production Cosmos were produced for dealership testing in 1965. Full production began in May of 1967 and lasted through 1972, though Cosmos were built by hand at a rate of only about one per day.

Cosmos were built in five batches:

Racing

In 1968, Mazda went racing with the Cosmo. They selected one of the most grueling tests in Europe to prove the reliability of the rotary engine, the 84-hour Marathon de la Route at the legendary Nürburgring circuit in Germany. Two mostly-stock Cosmos were entered, along with 58 other cars. One major change to the cars' 10A engines was the addition of a novel side- and peripheral-port intake system: A butterfly valve switched from the side to the peripheral port as RPMs increased. The engines were limited to 130 PS to improve durability. Detailed Nürburgring map showing both the Nordschleife and the new GP section. ... 12A redirects here. ...

The cars ran together in fourth and fifth place for most of the race, but the all-Japanese car was retired with axle damage in the 82nd hour. The other car, driven by Belgians, completed the race in fourth overall. This was to be the only racing outing for the Cosmo - the next Mazda race car would be a Familia Rotary (R100). The Mazda R100 used the chassis from the Familia and the rotary 0820 engine similar to the one used in the Cosmo Sport Series II. It was a 2 door 2+2 coupe and was produced from 1968 to 1973. ...


Series I

The Series I/L10A Cosmo was powered by a 0810 two-rotor engine with 982 cc of displacement and produced about 110 hp (thus the 110 name). It used a Hitachi 4-barrel carburetor and an odd ignition design - two spark plugs per chamber with dual distributors.

The front independent suspension was A-arm/coil spring design with an anti-roll bar. The rear used a live axle with a de Dion tube, trailing arms, and semi-elliptic leaf springs. Power-unassisted 10 in (254 mm) disk brakes were found in front with 7.9 in (201 mm) drum brakes in the rear. Performance in the quarter-mile (400 m) was 16.4 s, with a 115 mph (185 km/h) top speed. The price was lower than the Toyota 2000GT at 1.48 million yen (US$4,100).

Series II

The Series II/L10B was introduced in July, 1968. It had a more-powerful 128 hp (95 kW)/103 ft·lbf (140 N·m) 0813 engine, power brakes, 15 in wheels and a 5-speed manual transmission. The wheelbase had been expanded by 5.9 in (150 mm) for more room and a better ride. This Cosmo was good for over 120 mph (193 km/h) and could accelerate to cover a quarter mile (400 m) in 15.8 s. 12A redirects here. ...

The second generation CD Cosmo appeared in 1975 and lasted until 1981. It was known as the Cosmo AP in Japan, and sold internationally as the Mazda RX-5, though in some export markets its piston powered counterpart was called the Mazda 121 (a name later applied to Mazda's subcompact model).

Mazda America used the Mazda Cosmo name and offered it from 1976 through 1978. The CD Cosmo/RX-5 series was a flop internationally as Mazda tried too hard to "Americanize" the car. It was however an enormous success in Japan where over 55,000 where sold in the first year alone. Due to its poor sales as an export, the series-II version from 79-81 was not exported and remained on domestic sale only.


The Cosmo was Mazda's 'large' compact rotary coupe and based on the Mazda RX-4 floorpan and mechanics, but slightly heavier due to body design and more luxurious appointments, including an 5-link rear suspension and rear disc brakes. It was available with the 12A and 13B engines. The Mazda RX-4 (called the Luce Rotary in Japan) was a larger car than its rotary-powered contemporaries, the Capella-based RX-2 and Familia-based RX-3. ... 12A redirects here. ... 12A redirects here. ...


The Cosmo was affectionately referred to as the Japanese Grand Prix, and indeed was fitted out to compete with that class of American road cruisers. With the standard manual transmission, it was a surprisingly quick and responsive car to drive - as proven to the chagrin of many comparable sporty coupe drivers. Comfortable and well-equipped, it suffered from the bane of many Japanese automobiles (and American as well) of the period - poor rust-proofing and premature rusting. The rotary engine responded in an almost rheostat mode once it was above 2500 rpm, smoothly and quickly winding to the red line.

A piston engine version, the Cosmo 1800, used a 1769 cc (80x88 mm) straight-4 SOHC engine that produced 100 hp (75 kW) and 110 ft·lbf (149 N·m).

Mazda offered three versions of rotary engine for the HB series. A 12A-SPI, 12A-turbo and 13B-RESI. The latter available with automatic transmission only. The 1982 12A-turbo Cosmo coupe was officially the fastest production car in Japan at one stage.


The HB Cosmo was sold with its rotary engine option in Japan only. The sedan variant was replaced in 1986, but the Cosmo soldiered on unchanged until 1989.

Two engines were available, the twin turbo 13B-RE and the 20B-REW. The triple rotor 20B had 2 Liter(1962 cc) of displacement, which is quite large for a rotary powerplant. It produced 300 hp (224 kW) and 300 ft·lbf (402 N·m) with twin turbochargers. The JC series Cosmo set several firsts in Automotive history. Its 13B-RE + 20B-REW engines were the first series production twin sequential turbo systems to be offered for sale. The better known FD RX-7 didn't show its 13B-REW engine until early 1992. 12A redirects here. ... 12A redirects here. ...


This 4th generation JC Cosmo was way ahead of its time electronically as well (1990) by being the first production car with Car Control System, a CRT colour touch-screen controlling climate control, mobile phone, GPS car navigation, NTSC TV, radio and CD-Player.

Mazda Wankel engine - Wikipedia, the free encyclopedia (2205 words)
All Mazda Wankel "rotary" engines are essentially a single family - they all derive from the first Wankel experiments in the early 1960s (Wankel was a German Engineer).
The most prominent 4-rotor engine from Mazda was used exclusively for various Mazda-built GT cars (including the 767 and 787B) in replacement of the older 13J.
Mazda was fully committed to the Wankel engine just as the energy crisis of the 1970s struck.
