Top 10 Rotary Engined Mazdas You May Not know About

Mazda are renowned for their rotary engine so here are the top 10 classic rotary Mazdas you may not know about.

Rotary power is smaller, lighter and smoother than a conventional piston powered engine. Will we see a diverse range of vehicles like this again? Who knows, but Mazda really did put their engine in everything.

Mazda Rotary engine development began in 1961. Six painful years of problems and setbacks. The biggest was the appearance of chatter marks on the inner walls of the rotor housing. Known to Mazda “nail marks of the Devil” they appeared after a certain length of operation.

After much development the engineers solved the problem by the use of high-strength carbon seals infused with aluminum. Other automakers abandoned the rotary engine due to similar difficulties. The Mazda Cosmo Sport was the result of Mazda refusing to give up on the novel technology.

1967 Cosmo 110S

Ok, you probably do know this one, but I had to start somewhere, and so did Mazda. This was the first one they produced, and the first production car ever to be sold with a rotary engine.

1970 Capella Rotary RX-2 Coupe

The Mazda Capella Rotary or RX-2 from 1970 was a rotary engined version of the saloon or coupe. The RX-2 as it was known outside of Japan was also built in New Zealand and South Africa.

This was the only version of the Capella that was offered with a Rotary engine. The secong generation introduced in 1978 retained just Piston engines. It later became known as the 626 in export markets.

1974 Rotary Pickup (REPU)

Mazda had build the worlds only production rotary engined pickup. Known as the REPU, this small truck was only available in North America. Built between 1974 and 1977, just over 15,000 examples were made for the U.S. and Canada.

The 1.3 litre 13B four-barrel carbureted engine, flared fenders, and distinctive round taillights, the REPU was the world’s first—and only—rotary-engined pickup truck.

The REPU also had a racing career, its most notable victory being at the 1975 SCCA Mojave 24 Hour Rally.

1974 Parkway Rotary Bus - Top 10 Rotary Engined Mazdas You May Not know About

This has to be my favourite. I bet you weren’t expecting a rotary engined bus. But why not.

Built for only three years, the Parkway was based on Mazdas Titan truck chassis. It came with conventional petrol and Diesel power too. However, the roatary version was a bit special. The 13B was tuned for arouns 135bhp and could get the bus over 70mph. Word has it that the bus was smooth and quiet. Built as a low emission version they only made 44 of them. I think it’s fantastic.

1969 Luce Rotary Coupe

The pretty Luce Rotary Coupe was introduced in 1969. Sadly this was only ever intended for the domestic market, but you can see that it would have sold well in in the US or Europe. What is unusual about this one is that it is the only front wheel drive rotary car Mazda ever produced.

Known as the R130  it was produced over four years until 1972. They only made 1000 of them, making it very rare. It was also expensive, costing from 1.45 to 1.75 million Yen. This was Mazda’s first step into the luxury personal car market. They even displayed the car at 35 major department stores.

Probably the best looking Mazda ever.

1975 Roadpacer AP

The Roadpacer AP was the largest of the rotary passenger cars. Produced in partnership with General Motors, the car was based on the Holden HJ Premier. The AP stood for Anti-Pollution, a large car with with a small engine. Somehwat ironic when the fuel economy was reported to be around 10mpg.

The engine made less power than the equivalent Holden, but also much less torque. The performance of the car wasn’t much to get excited about. But it was meant for Japanese dignitaries, so speed may not have been much of an issue. Those government departments managed to crash many of them, so there aren’t a lot left. They only sold around 900 of them in the first place. And it was General Motors only rotary powered car.

I rather like the style, I think I could live with the poor fuel consumption.

1968 Familia R100 Coupe

The R100 was based on the Familia 1200 coupe that was already in production. Taking the inline 4 cylinder engine and replacing it with the 10A rotary from the Cosmo. The R100 was the name Mazda gave the car outside of Japan. The R100 was also one of the first cars Mazda imported to the United States.

It was also a racing success. At the 1969 Grand Prix of Singapore the R100 was immediately successful, winning on its first outing. The Spa 24 hours was next so Mazda entered a pair of R100s. The two cars finished fifth and sixth after a group of four Porsche 911s.

1972 Savanna GT / RX-3

The Savanna was introduced in 1971 and of course was available with rotary power. This time in the form of the 10A engine. But it’s the GT with the larger 12A engine that started something. You see, this is where the RX7 came from. the first was exported as the RX-3

The Savanna was Mazda’s performance coupe at that time. Regularly competing with Nissan, the Savanna eventually beat the Skyline GT-R. By 1976 the model had its 100th victory in Japanese motor sports. A record for a single model car. By 1978 the model had been replaced with the Savanna RX-7, with the pretty pop up headlight coupe.

1990 Eunos Cosmo

Mazda created many sub brands over the years. The Eunos name was brough back to create a more sporting range. This stylish 1990 coupe was full of the latest electronic technology too. Apparently the first car ever to have a touch sensitive sat nav system. Also the largest production rotary car too.

There were a choice of two engines, the 1.3 litre 13B RE or a three rotor 2-litre 20B REW. The larger engine was available with twin sequential turbochargers. It was said to be as smooth if not smoother than a V12.

There are more rotary engined Mazdas than just in this top 10.There’s a brilliant book on Rotary Mazdas by Marc Cranswick.

I do think a Parkway would suit me, it’s practical after all. But the Stylish 1990 Eunos Cosmo coupe is a very tempting. Which one do you want?

There’s more Mazda in the 100 Year Anniversary Article.
