Working from the crankcases out, the 'phase 2' engine sees the crank thrust bearing relocated to the rear of the shaft – this reduces the transfer of natural frequencies to the transmission, resulting in improved NVH. The low and wide engine structure also lowers the vehicle's centre of gravity and improves mass distribution. Strength is also an advantage of the boxer design – the crankshaft is sandwiched between the left and right hand crankcases and is supported by 5 main bearings. This results in reduced noise, vibration and less power loss.

Due to the balance afforded by horizontally opposed cylinders, the crankshaft requires less weighting and there is no need to install balance shafts. According to official Subaru literature, there are several advantages to the boxer design. The B4 is powered by a 'phase 2' all-alloy DOHC, 16-valve, intercooled turbo 2-litre boxer four. In 2002, the B4 RS30 was introduced with a naturally aspirated 3.0 L EZ30 DOHC flat-six engine. In 2001, a B4 RS25 model was introduced with a naturally aspirated 2.5 L DOHC engine. Ī B4 TS-R model was equipped with a less powerful, naturally aspirated 2.0 L DOHC AVCS engine, but shared many of the body and suspension components of the more powerful RSK.

This results in a 0–60 mph time of 5.6 seconds for the manual and 6.6 seconds for the automatic. The B4 moniker also applied to naturally aspirated models, such as the 2.0 L TS-R.Īustralia models (called B4) were detuned to run on lower octane (98 RON) fuel and were rated 258 PS (190 kW 254 hp) for the manual and 239 PS (176 kW 236 hp) for the automatic models. This engine was popular with Japanese buyers due to reduced tax liability based on Japanese vehicle size legislation the car offered performance advantages over larger cars sold in Japan with bigger engines but with a smaller tax bill. This results in a 0–60 mph time of 5.2 seconds for the manual and 5.8 seconds for the automatic. The RSK featured the familiar DOHC, twin-turbo 2.0 litre engine rated 276 bhp (206 kW) ((265 bhp (198 kW) for automatic with manual mode). The B4 model was introduced for the third generation and was a sedan-only model. The Legacy is the only vehicle in this class that provides AWD as standard equipment. In late 2000, the EZ30, a newly designed 3.0 L H6 was offered in the Outback and Lancaster (Japan) models.
Even though dimensions became mid-sized, it was still rated by the EPA as a compact car.įlat roof wagons are no longer manufactured worldwide, and instead the raised roof is used for both the Legacy and Outback wagons (Lancaster in Japan). World-market and Japanese models ranged from a normally aspirated 2.0 liter flat-4 to the EZ30 in the 3.0R model. Production in the United States lasted through 2004.Īt its introduction in 1999, it won the Automotive Researchers' and Journalists' Conference Car of the Year award in Japan.Īll models were equipped with standard, symmetrical all wheel drive. In all markets except for the United States, production lasted through 2002, with a limited production Blitzen model sold mid-cycle under the 2003 model year in Japan. Subaru launched the third generation Japanese and world-market Legacy in June 1998, while the North American model was introduced in May 1999 for the 2000 model year.
