The fifth generation Legacy/Outback and the JDM Subaru Exiga received a newly revised CVT under the Lineartronic name. It is a metal chain, pulley-based CVT, which is considered the most reliable, due to the simplicity of the pulley system and durability of the metal chain. In addition, the metal chain pulley system is generally quieter than other CVT designs.
In the US, the Lineartronic is available with the 2.5i engine in the Outback, Legacy and Forester(2014), and the 2.0 FB engine in the Impreza and slightly modified for the XV Crosstrek. In SE Asia this transmission is also available for the 2.0i engine for the 2010 and later Legacy Legacy Asia spec. Subaru claims that the transmission provides “uninterrupted power that maximizes fuel efficiency while keeping the engine at the optimal rev range”. EPA mileage estimates for the CVT with the 2.5i, naturally aspirated based engine, claim 30 MPG highway (29 Outback, 31 Legacy).
Lineartronic uses a specially modified torque converter to connect the engine to the transmission. It can slip like a traditional torque converter, but remains locked under all conditions except when coasting or traveling at very low speed. The persistent lockup condition under acceleration provides the efficiency and control of a clutch while still behaving much like a traditional planetary automatic transmission. The transmission can also be manually controlled by the driver by providing the ability to select 6 or 7 (if paired with a Diesel engine) different “virtual” gears, where the transmission will hold a particular ratio.
