In contemporary automobiles, rotary engines maintain their status as an uncommon choice despite their manifold advantages and the inherent allure of their technology.
These powerplants exhibit a notable distinction: a reduced number of moving components, eschewing the reciprocating motion in favor of a circular one. This unique characteristic imbues rotary engines with a heightened degree of smoothness and a significantly diminished susceptibility to mechanical failures compared to their reciprocating counterparts.
For those harboring an affinity for rotary engines, it is imperative to recognize that their utility extends beyond just cars. Indeed, some helicopters and aircraft also employ these more efficient engines, offering a broader perspective on their applications.
Another salient detail to consider is the compact physical footprint of rotary engines relative to most reciprocating counterparts. This reduced size affords additional space within the vehicle, accommodating an array of supplementary equipment and features.
Unfortunately, the drawbacks associated with rotary engines should not be dismissed lightly. Various factors contribute to the potential failures of rotary engines, thus rendering the vehicles employing them as exclusive or novelty options. In light of these challenges, one’s knowledge of the top 10 cars featuring rotary engines becomes imperative, as it paves the way for selecting vehicles that deliver commendable performance and longevity, even in the presence of a rotary machine.
10 Cars With Rotary Engines
Chevrolet Aerovette:
The Aerovette, a formidable representative of Chevrolet’s automotive lineage, harmoniously marries retro-futuristic aesthetics with aerodynamic contours. Regrettably, this gem from the ’70s did not have the opportunity to shine in rotary-engine vehicles.
NSU Wankel Spider:
The Wankel Spider, a pioneering creation from NSU in the ’60s, represents one of the earliest instances of rotary engine implementation. Exuding to the quintessential style of the ’60s, this model achieved a modicum of reliability despite its limited production run of just over 2,000 units.
Mazda Eunos Cosmo:
The Eunos Cosmo holds a distinguished position among rotary engine cars, boasting a production span from 1967 to 1995. As the first Cosmo to adopt the Mazda Wankel engine, it occupies a significant niche in the annals of rotary engine history. The Cosmo also boasts an illustrious racing legacy and underwent various production iterations, with the Series JC standing out as the first to feature two turbos on a rotary engine vehicle, offering heightened torque and performance. It was also a pioneer in integrated GPS technology.
Citroen GS Birotor:
The Citroen GS Birotor blends retro aesthetics with futuristic design, captivating enthusiasts with its disc brakes and opulent interior. However, its voracious appetite for fuel, a common trait among rotary engine vehicles, contributed to its downfall as fuel prices surged. While a few collectors still covet this rarity, it remains an exceedingly scarce find.
NSU RO 80:
NSU‘s foray into rotary engines, featuring advanced design and comfort, marked a turning point. Frequent engine rebuilds and many issues tarnished its reputation despite later iterations addressing these concerns. The early engine woes left an indelible mark on the model’s image.
Mazda B-Series:
Mazda’s B-Series truck is unique to this list due to its small truck classification. Despite garnering popularity in the United States with nearly 15,000 units sold between 1974 and 1977, it, too, suffered from reliability issues that marred its reputation. While a handful of these trucks persist today, they remain elusive finds.
Mazda RX-8:
For those seeking a more contemporary rotary engine experience, the 2003 RX-8 presents a viable option. This 4-door marvel maintains its reputation for reliability and safety while remaining attractive. Despite production cessation in 2012, it remains a steadfast choice, bolstered by advanced safety features that ensure a secure driving experience.
AMC Pacer:
The Pacer, a miniature vehicle featuring a Wankel motor, carves its niche in the annals of rotary engine history. Tailored for families and compact car enthusiasts, its wooden side panels embody the era in which it thrived. The Pacer endures as a retro gem, equipped with bucket seats, robust stabilizers, and other commendable features.
Mazda 787B:
Mazda’s reputation as a rotary engine pioneer finds validation in the 787B, originally conceived as a racing machine. Despite initially lagging behind the competition, this vehicle demonstrated its true grit in the later stages of races, surpassing other contenders. The 787B also earned acclaim for its remarkable reliability within the competitive realm of racing.
Mercedes C 111:
The Mercedes C 111 diverges from conventional consumer vehicles, conceived primarily as a research project. Its enduring allure derives from its stylish design and futuristic elements. Equipped with a three-rotor Wankel engine, this model achieved an impressive top speed for its time, albeit encountering roadblocks related to U.S. emissions standards, ultimately leading to its discontinuation.
These rotary-engine vehicles, each with unique charm and history, offer various choices for enthusiasts and collectors alike. While rotary engines may present their challenges, the allure of their distinctive technology endures, ensuring their place in automotive history.
