Drive Mechanism:

Timing Belt (requiring periodic replacement as per maintenance schedule).

🔧 Transmission

Transmission Type:

Front-engine, Symmetrical All-Wheel Drive (AWD) with either a 5-speed manual transmission or a 4-speed automatic transmission (with optional VTD-AWS for higher trims).

Transmission Options:

The manual will detail both the 5-speed manual and the 4-speed automatic transmissions available across different engine and trim levels.

AWD System:

Detailed information on Subaru's Symmetrical All-Wheel Drive system, including viscous coupling center differential and rear differential operation, depending on transmission type.
