Cars of Futures #8211; Mazda Cosmo

At the dawn of the 1960s, was a little-known Japanese manufacturer of trucks, with a single commuter car (the R-360) to its Like other Japanese of the day, Mazda had great for its future, and it saw the Felix Wankel-developed engine as the distinction it needed to above the rest of its Japanese

Just as the rotary engine was as bold and futuristic for its promise of in a compact, lightweight package, no car would do to introduce the Mazda to a global audience. Looking for impact, Mazda debuted its own of the two-rotor Wankel engine in a sport coupe that to blend the best of styling both Europe and Japan. its new car the Cosmo, Mazda forever its reputation as a manufacturer of cars for eschewing the shortest route two points in favor of the most

In the late 1950s, Felix innovative design for an entirely new combustion engine seemed to far more promise than the and inefficient piston engine. The engine was able to produce power from a much and lighter package than piston engines, and held the advantage of having fewer parts to fail.

Eventually, engines became known for smooth running and stratospheric though these benefits not without offsetting drawbacks. In of 1961, Mazda#8217;s parent, Kogyo, became the fourth of the Wankel engine from the holder, German automaker

Mazda#8217;s work on the rotary began immediately after it had the rights from NSU, and delivery of the first NSU-branded even took place. By of 1963, the company had completed two 798cc Type 8A engines to testing, and for the 1964 Tokyo Show company president Matsuda drove the first prototype (now with an 982cc 10A engine) onto the stand.

Still, problems with enhanced rotary engine persisted. Apex seals, at the tip of each rotor#8217;s three wore quickly, causing the to lose compression (and power) while increasing oil and boosting noxious emissions. To this problem, Mazda#8217;s developed apex seals used both carbon and in their construction, which to be far more durable than the hollow cast-iron design.

In some 80 prototypes were using the improved apex design, and the bulk of these (75 were shipped to Mazda as evaluation units. This Mazda to generate a large of #8220;real time#8221; data on the in a fairly short period of and by the close of 1966 the design of the 982cc 0810 rotary was finalized. It would come to producing some 110 horsepower, to get the lightweight Cosmo through the mile in 16.4 seconds.

Production of the Cosmo coupes in May of 1967. and the car featured far more just a revolutionary engine in sensuous sheetmetal. Mazda was on using the Cosmo as a halo and each came with front brakes (coupled rear drums), an independent suspension featuring an anti-roll bar and an instrument display that a speedometer, tachometer, oil pressure water temperature gauge, gauge and clock. Less 350 examples of the Series I Cosmo built before Mazda the Series II car in July of 1968.

Series II Cosmo models on the lessons learned from the I cars, and included such as a more powerful (and expensive) 0813 rotary now rated at 128 horsepower and 103-lbs.ft. of larger wheels (15-inch, 14-inch on the original models); a transmission (versus the original#8217;s power brakes (still discs up front and drums in the a longer wheelbase for improved quality and better interior and a larger grille area for cooling and more distinctive The Series I#8217;s live axle and rear leaf were retained, but the improved shaved 0.6 seconds off the original#8217;s time, while boosting top from 115 MPH to 120 MPH.

Mazda constructed 1,176 II Cosmos models, but only six known to have been into the United States. that#8217;s hardly a significant even for a low-volume manufacturer Mazda, it did pave the way for later rotary-engined automobiles like the RX-3, RX-4 and RX-7.

In as automakers like Mercedes-Benz, Motors, Toyota and Rolls-Royce beginning to abandon the idea of a future, Mazda stuck its compact and (relatively) powerful evolving it from the 0813 to the 12B and eventually the 13B and its many variants the complex but powerful turbocharged as found in the last Mazda sold in the United States). 13B-MSP Renesis engine, as in the Mazda RX-8, has the distinction of the final production rotary built by Mazda. though is that Mazda is still the design of an improved rotary that blends improved with better fuel and reduced emissions.

Though the rotary engine#8217;s nature and relatively low torque make it suboptimal for use in mainstream cars (and only suitable for use in sports cars), its nature and adaptability for multi-fuel use may make it the engine of choice for use in hybrid automobiles (like the Volt), where an internal engine is used to power a providing electricity to power the drive and recharge onboard batteries. While both the Cosmo and the Mazda rotary may be out of production (at least temporarily), the effort expended by Mazda on engine design may once pay dividends, helping to power cars of tomorrow.
