All the Mazda rotary engines have been praised because of their light weight. The unmodified 13B-MSP Renesis Engine has a weight of 112 kg (247 lb), including all standard attachments (except the airbox, alternator, starter motor, cover, etc.), but without engine fluids (such as coolant, oil, etc.), known to make 157–175 kW (211–235 hp).
Although Mazda is well known for their Wankel "rotary" engines, the company has been manufacturing piston engines since the earliest years of the Toyo Kogyo company. Early on, they produced overhead camshaft, aluminum blocks, and an innovative block containing both the engine and transmission in one unit.
Mazda America used the Mazda Cosmo name and offered it from 1976 through 1978, fitted with the 13B rotary engine. [6] In the United States, the Cosmo was replaced by the smaller, lighter, and sportier Mazda RX-7. Due to its poor sales as an export, the Series II version, built from 1979, was not exported and remained a Japanese domestic sale only.
Yanmar of Japan produced small, charge-cooled rotary engines for chainsaws and outboard engines. [203] One of its products is the LDR (rotor recess in the leading edge of the combustion chamber) engine, which has better exhaust emissions profiles, and reed-valve controlled intake ports, which improve part-load and low rpm performance.

English: The lightly tuned 13B engine in a (some nice Racing Beat parts) 1992 Maxton Rollerskate (car number 16) in Garnet at a Caffeine & Carburetors event in New Canaan, CT. Amazing to finally see one of these in real life. 13B rotary engine, very good condition.
Another Corvette concept, XP-897GT, also appeared in 1973, which used a 2-rotor engine. However, with the energy crisis of the time, GM scrapped its rotary development work and all plans for a Wankel-powered car. The XP-897GT 2-rotor Concept was sold to Tom Falconer and fitted with a Mazda 13B rotary engine in 1997.
It featured a 12A carbureted rotary engine as well as the option for a 13B rotary engine with electronic fuel injection in later years. The second-generation RX-7, sometimes referred to as the FC, was offered as a two-seater coupé with a 2+2 option available in some markets, as well as in a convertible body style.
