What Cars Have Rotary Engines? The Complete List (From Spy Cars to Sports Icons)

Rotary engines have powered some of the most fascinating — and bizarre — cars ever built. From a German roadster that bankrupted its maker to secret KGB pursuit sedans, the story behind what cars have rotary engines is wilder than most people realize. Stick around — you’ll want to see the full list.

What Is a Rotary Engine, Anyway?

Before diving into the car list, here’s a quick breakdown.

A rotary engine — technically called a Wankel engine — ditches the traditional up-and-down pistons entirely. Instead, a triangular rotor spins continuously inside an oval-shaped housing, handling intake, compression, combustion, and exhaust in one smooth, continuous motion.

German engineer Felix Wankel first prototyped the design in the 1950s. The result is an engine with far fewer moving parts, a compact size, and silky-smooth power delivery at high RPMs.

The downsides? Poor fuel economy, incomplete combustion, and notoriously fragile apex seals — the tiny components at each tip of the rotor that must seal pressurized combustion chambers while spinning constantly. These three problems shaped the entire history of rotary-powered cars.

The First Cars With Rotary Engines: Europe’s Expensive Experiments

NSU Wankel Spider (1964–1967)

The NSU Wankel Spider holds the title of the world’s first production car with a rotary engine. NSU debuted it at the 1963 Frankfurt Motor Show, and it entered full production in 1964.

Styled by Italian design house Bertone, this little two-seat convertible carried a 500cc single-rotor engine producing 50 horsepower. That’s impressive for such a tiny motor — but the apex seals wore out fast, leading to constant engine rebuilds.

Production stopped in 1967 after just 2,375 units. Fewer than 150 are thought to survive today.

NSU Ro 80 (1967–1977)

Rather than retreat, NSU doubled down with the Ro 80 — a futuristic luxury sedan with a 995cc twin-rotor engine producing 113 horsepower. It won European Car of the Year in 1968 and featured four-wheel disc brakes, power steering, and a semi-automatic transmission.

It was technically brilliant. It was also financially catastrophic.

Apex seal failures caused engines to die well before 30,000 miles. NSU replaced thousands of engines under warranty until it went broke and was absorbed into what became Audi. Despite the nightmare, the Ro 80 stayed in production until 1977, with over 37,000 units built.

Citroën M35 (1969–1971) and GS Birotor (1973–1975)

France wanted in. Citroën partnered with NSU to form Comotor, a joint venture to mass-produce rotary engines.

First came the M35 — a prototype coupe built in just 267 units and handed to vetted customers who had to drive a minimum of 18,500 miles per year. It was essentially a paid real-world test.

Then came the GS Birotor, launched in 1973 with a twin-rotor 107-horsepower engine. It launched right into the 1973 oil embargo. The Birotor was thirsty, expensive, and priced 70% higher than the regular GS.

Citroën killed it in 1975 after fewer than 900 units. Then they bought most of them back and crushed them to avoid supplying spare parts for a decade. Today it’s one of the rarest cars in Europe.

The Big Names That Almost Built Rotary Cars

Mercedes-Benz C111 (1969–1970)

Mercedes didn’t want to sell a rotary car — they wanted to test the limits of the engine. The C111 series was a line of gullwing-door experimental supercars that never reached the public.

The 1969 version used a three-rotor Wankel with 280 horsepower. The 1970 C111-II stepped up to a quad-rotor engine producing 350 horsepower, hitting 186 mph — hypercar numbers for 1970. Mercedes eventually pulled the Wankel engines out and dropped in V8s when they realized the fuel consumption was never going to pass emissions regulations.

General Motors’ Rotary Corvette Concepts (1973)

GM’s rotary push was led by company president Ed Cole, who saw the engine’s compact size as the future of American car design.

The result was the Corvette XP-897 GT, a mid-engine concept built on a modified Porsche 914/6 chassis with a twin-rotor engine making 180 horsepower. GM also showed a larger Four-Rotor Corvette concept alongside it.

Then the 1973 oil crisis hit. The EPA tightened emissions. GM killed the entire rotary program and billions in research went nowhere.

The AMC Pacer’s Rotary Problem

Here’s a strange piece of trivia. The AMC Pacer’s famously bulbous, stubby shape wasn’t an aesthetic choice — it was forced by the rotary engine it was designed around. AMC had a deal to buy GM’s rotary engines for the Pacer. When GM cancelled its program, AMC was left with a chassis built for a compact rotary and no engine to fit it.

Engineers had to jam a heavy inline-six into a bay not designed for it. The result wrecked the weight distribution and handling — and turned the Pacer into an industry joke.

Mazda: The Only Brand That Truly Mastered the Rotary Engine

No other company came close to Mazda’s commitment to the rotary. In 1961, Japan’s government pressured smaller automakers to merge with giants like Toyota or Nissan. Mazda needed a technological identity to survive independently. They bet the company on fixing the Wankel engine.

A team of 47 engineers led by Kenichi Yamamoto attacked the apex seal problem. They called the early failures “the nail marks of the Devil.” By 1972, Mazda developed a chrome-plated rotor housing and a carbon-aluminum composite apex seal that actually lasted. They’d solved what bankrupted NSU.

Mazda Cosmo Sport 110S (1967–1972)

The Cosmo Sport was Mazda’s grand entrance — the world’s first volume-production twin-rotor sports car. It used the 10A engine with 110 horsepower in its original form, later bumped to 128 horsepower in the Series II version.

It was slow to build — only about 30 units per month — and just 1,176 were ever made. They’re serious collector pieces today.

Mazda’s Mainstream Rotary Lineup

After the Cosmo Sport proved the engine could work, Mazda spread rotary power across its passenger car range throughout the early 1970s.

The RX-3 became the most popular early rotary, with over 900,000 units built globally. It even snapped Nissan Skyline GT-R’s 50-race winning streak at the 1972 Fuji Masters 250.

Mazda’s Strangest Rotary Vehicles

Mazda’s obsession with the rotary engine produced some genuinely odd machines:

• Rotary Engine Pickup (REPU) (1974–1977): The only mass-produced rotary pickup truck in history. Sold in North America only. Quick off the line, but got around 16.5 mpg and lacked towing torque. Over 15,000 were built.
• Mazda Parkway Rotary 26 (1974–1977): A 26-passenger commercial bus with a rotary engine. Smooth ride, terrible torque for a heavy bus.
• Mazda Roadpacer AP (1975–1977): Mazda imported Australian Holden Premier bodies and stuffed a 1.3-liter rotary inside. The engine was far too small for the huge body. Dreadful performance, worse fuel economy.
• Mazda RX-5 Cosmo AP (1975–1981): A heavily Americanized luxury grand tourer. Big hit in Japan, commercial failure everywhere else.

The RX-7 and Eunos Cosmo: The Golden Era

After getting burned by the 1973 oil crisis, Mazda made a smart pivot. Mainstream commuters wouldn’t tolerate the fuel consumption. But sports car buyers would happily trade economy for a high-revving, smooth engine.

Mazda RX-7 — Three Generations of Pure Sports Car

• FB Generation (1978–1985): A lightweight, front-mid-engine sports car with a perfect 50/50 weight balance. Built around the 12A rotary. Hugely successful globally.
• FC Generation (1985–1991): Turbocharging arrived. Rotary engines and turbos are a natural match — the continuous exhaust flow spools turbos fast and smoothly.
• FD Generation (1991–2002): The icon. The 13B-REW engine used Japan’s first mass-produced sequential twin-turbo system. Peak power came in waves as the primary turbo handed off to the secondary. The FD is universally considered one of the best sports cars of the 1990s — though its thermal sensitivity demanded careful maintenance.

Eunos Cosmo (1990–1995): The Only Three-Rotor Production Car

The Eunos Cosmo sits in a category completely alone. It’s the only mass-produced car ever to use a triple-rotor Wankel engine — the 20B-REW, displacing 2.0 liters across three rotors with sequential twin turbos.

Official output was capped at 276 horsepower due to a Japanese manufacturer agreement to limit advertised power. In reality, the engine produced well over 300 horsepower in stock form. It was also one of the first production cars with a built-in GPS navigation system featuring a color touchscreen.

Mazda RX-8 (2003–2012)

The RX-8 was Mazda’s attempt to meet modern emissions standards with a new Renesis rotary engine. The clever fix? Moving the exhaust ports from the outer housing to the side plates, eliminating the overlap between intake and exhaust that had always allowed unburned fuel to escape.

The Renesis revved to a staggering 9,000 RPM and the RX-8’s balanced chassis earned genuine praise. But apex seal issues and ignition coil failures followed the car throughout its life. When Euro 5 emissions rules tightened, Mazda pulled the plug in 2012.

The Rotary Cars You’ve Never Heard Of: Soviet KGB Pursuit Ladas

This one surprises most people. While Mazda was building sports cars, the Soviet Union was running its own secret rotary engine program — and its purpose had nothing to do with performance enthusiasts.

The KGB needed pursuit vehicles that could catch modern Western cars. But retooling Soviet factories for new high-performance piston engines was too expensive. The solution? Reverse-engineer the Wankel engine and hide it inside totally ordinary-looking Lada sedans.

Starting in 1978, AvtoVAZ built the VAZ-21018 — a standard Lada 1200 hiding a single-rotor engine. Early apex seals failed badly, often before 12,500 miles, but the program pressed on.

By the 1980s, twin-rotor Lada Riva sedans (VAZ-21059 and 21079) were making 120–140 horsepower. They looked identical to the 60-horsepower civilian models. A VAZ-21059 could hit 112 mph. Some GAZ Volga executive sedans reportedly ran triple-rotor engines producing over 205 horsepower — built specifically for top-level KGB directors.

The program quietly ended in 2004 when the Soviet design bureau was dissolved.

The Rotary’s Unlikely Comeback: The Mazda MX-30 R-EV

The traditional rotary engine’s weaknesses — bad fuel economy under varying loads, poor low-end torque, thermal fragility — make it a poor fit for modern driving regulations. But its strengths — tiny size, light weight, vibration-free operation — make it nearly perfect for one specific job: generating electricity.

In 2023, Mazda launched the MX-30 e-Skyactiv R-EV. It’s a plug-in hybrid where a new 0.8-liter single-rotor 8C Wankel engine has zero mechanical connection to the wheels. When the battery depletes, the rotary spins at a single, steady, optimized RPM to generate electricity and recharge the battery. Running at a constant speed eliminates almost all the thermodynamic problems that plagued rotary cars for decades.

The fully electric MX-30 sold fewer than 600 units in the US before Mazda discontinued it there. But the R-EV variant — currently sold in Europe and Japan — proves the rotary engine found its best role not as a driver, but as a quiet, compact, spinning generator that no other engine format can match for size and smoothness.

The Wankel engine didn’t die. It just found the job it was always best suited for.
