You are looking at the sixth-generation Subaru B4 sedan. It pairs gasoline engines with a CVT and all-wheel drive, and the examples here show how those powertrains and equipment packs are arranged.
The Subaru B4 engine choices in this generation are gasoline powertrains with a continuously variable transmission and all-wheel drive. The 2.5 CVT sedan covers daily commuting, while the 3.6 CVT example gives the drivetrain more pull when you want extra pace on the highway.
Subaru B4 trim levels sit on a technical version rather than replacing the engine. On the 2.5 CVT sedan, Classic and Eyesight change assistance and cabin equipment you live with every day, while the gasoline CVT and all-wheel-drive layout stay the same.
