The EN series engine is a four-cylinder, four-stroke engine used in kei cars sold by Subaru in Japan, succeeding the EK family of two-cylinder engines previously used in Subaru kei cars from 1958 to 1989. The EN family was introduced in 1989 (as the EN05) and discontinued in 2012.
76-645: It was a replacement for the two-cylinder EK23 that was used in the Subaru Rex . While other manufacturers adopted a three-cylinder engine, the Subaru EN is a four-cylinder of only 547 cc. Subaru also did make a three-cylinder engine, called the Subaru EF engine which was used in the Subaru Justy , but the larger EF engine (which was based on the smaller EK23) was not modernized at the same time. The following year, 1989,
152-453: A 37 PS (27 kW) double carburetor for the sporty GSR. The TS (Touring Sport) received a 35 PS (26 kW) iteration. The GSR was also somewhat lower than its counterparts, due to radial tires being fitted. In October 1973 the two-stroke was replaced by a 358 cc rear-mounted, watercooled, two-cylinder, four-stroke engine called the EK21 . This produced 31 PS (23 kW) at

Then, in response to the very low priced Suzuki Alto , a decontented version of the Van called "Family Rex" was added in October 1979. It was priced at a very low ¥480,000 (under US$ 2,000 at the time). An automatic clutch option was added on several Rex models in March 1980. In August 1981,

Because the R-2 was based largely on the 360, originally including its air-cooled two-stroke engine , it lasted for not even three years.

1976-661: The EN07 powered three of the five most fuel efficient kei passenger cars in 2009 (heading the list for the third year in a row), when the EN engine was its peak of development. There was a turbocharged version of the predecessor, the EK23, used in the Subaru Rex, which competed with the Daihatsu Mira and Suzuki Alto. This was replaced with a supercharger for the EN-series. The four-cylinder EN engine
2052-892: The Japanese Ministry of Transport revised the standards for kei cars . This resulted in the new 660 cc class series of four-cylinder engines, and the EN05 had its stroke increased to produce the EN07. The bore pitch remained 62.5 mm (2.46 in) to help keep the changes to a minimum. The increased stroke helped make up for the lack of low-speed torque, a weakness of the other four-cylinder 660 cc engines. While four-cylinder engines are not typical in kei class cars, Subaru kept using this layout until they stopped manufacturing their own kei vehicles in 2012. Three-cylinder engines have proved to be on par with Subaru's four-cylinder designs; while not as smooth running they tend to be lighter and more economical due to lower friction losses. Nonetheless,
2128-596: The Japanese domestic market. The end for the Rex came in March 1992, when it was replaced by the Vivio . A total of 1,902,811 Subaru Rexes were built in its lifetime. Recently the Rex has become somewhat of a cult car in Japan, being popular in front-wheel-drive drift events.

A supercharger meant less lag than for a turbo, although specific output tended to be somewhat lower than the competition. This was available for both the 3- and 5-door versions. May 1988 saw an available electrically deployed canvas top added to
4864-407: Was also equipped with pink and blue pinstriping from the factory, and a two-year, 50,000 km warranty was offered when new. Equipped with a different engine, the Fiori had Subaru's 758 cc carburetted four-cylinder EN08 powerplant. This engine, producing 42 PS (31 kW) at 6,000 rpm, was also used in those European markets that received the Rex and in New Zealand's Ace. In Europe it

5016-489: Was dropped. The Van version received a 28 PS (21 kW) engine (at 6000 rpm) with the same torque, albeit at 500 rpm lower. Van equipment levels were Standard and Super Deluxe. This version (called the Subaru 500 in the export) was short-lived, replaced by the bigger Rex 550 exactly one year after being introduced. The Rex 550, introduced in May 1977, featured the SEEC-T equipped watercooled, two-cylinder, four-stroke 544 cc EK23 series engine. Chassis code

5168-447: Was fitted with this version from its debut. It has a variable valve timing DOHC head and direct ignition. Used in: The Vivio RX-R was developed at the time that the DOHC head design appeared. It adopted direct push and a high lift cam like Toyota, but the timing belt drives only the exhaust camshaft; the method of driving the intake cam is synchronous from there. This 660 cc DOHC narrows
5244-568: Was installed in the early Sambar van and truck. Compression ratio dropped slightly, and tuning emphasized low-rpm torque. Used in: The EN07A engine (with a carburetor) became EN07E with EMPi. Used in: The EN07C engine (with a carburetor) became EN07F with EMPi. The rocker cover on the delivery service version had a crimson ceramic coating. Was installed in the Pleo Van EGI SPI (single point injection) engine design. Used in: The EN07F with EMPi became an EN07V with SPI. The rocker cover on
5320-461: Was not installed on the lowest spec versions (Type B, Standard). In March 1978 the Swingback version was added, a two-door sedan which received a larger, opening rear window.

In March 1979, the Rex underwent

5472-466: Was originally marketed as the Clover 4 , and Subaru cast the head with a clover-leaf mark, to set it apart from its three-cylinder version. Subaru remained faithful to the EN-series until they stopped building kei car engines. Subaru uses Daihatsu three-cylinder units for the Sambar truck (now a rebadged Daihatsu Hijet ) since 28 February 2012. The EN05 was the first engine in the EN series. Variants include
5548-492: Was produced for nine. The Subaru Rex represented a fresh start designwise, sharing little of its appearance with the Subaru 360, although they were mechanically the same and shared a rear-engine layout . The Rex also retained the 360/R-2's rear swing axle . The appearance of the new Rex was similar to Subaru's new compact car, the Leone . The Rex originally featured the same water-cooled 356 cc EK34 two-stroke engine as used in

5700-599: Was rebadged M80 to reflect the engine displacement. The M80 was available as a three or a five-door, in DX and SDX versions, with the SDX receiving a standard five-speed manual. Top speed was 125 km/h for four-speeds, 130 km/h for five-speeds. This generation Rex was marketed as the Viki in certain Southeast Asian markets, a name which was also used for a special edition (Rex ViKi) in
