What: Long stroke, small bore
Why: Efficient combustion, improved fuel economy, lower emissions
Inside the XV Crosstrek resides the latest evolution of the world-renowned SUBARU BOXER engine. A difference you not only feel, but can physically see. It’s a long-stroke engine with small, compact combustion chambers and small ports. Meaning? Air and fuel are rapidly and more evenly mixed, directly contributing to not only increased engine power, but fuel efficiency and lower emissions. So much so, that the XV Crosstrek has been awarded Partial Zero Emission Vehicle (PZEV) 1
1. 2013 Subaru Impreza and XV Crosstrek 2.0L, and Forester, Outback, Legacy 2.5L non-turbo models achieving a Partial Zero Emission Vehicle (PZEV) rating by the California Air Resources Board are available in all 50 states. Only those registered in California, Connecticut, Maine, Maryland, Massachusetts, New Jersey, New York, Rhode Island and Vermont will be eligible for the 15 years/150,000 miles emission warranty. Oregon, Pennsylvania and Washington vehicles are not covered under PZEV emissions control warranty. See your warranty maintenance booklet for additional information.
CVT CHAIN DRIVE
What: Forgoes the typical steel belt for a chain belt
Why: Lighter, more compact, better fuel economy
The XV Crosstrek Lineartronic CVT (Continuously Variable Transmission) goes against the grain in more ways than one, and for the greater good: Its chain belt has a smaller minimum engagement diameter, so the same ratio coverage as a typical steel belt can be achieved – and then some – with smaller pulleys; thus it can be lighter and more compact, and uses significantly less fuel.
SYMMETRICAL ALL-WHEEL DRIVE (AWD)
What: Continuous AWD (5MT) or Active AWD (CVT)
Why: Superior control and handling
Subaru is long held as the ultimate innovator of AWD, making a symmetrical system for maximum stability and efficiency. The XV Crosstrek takes it a step further, with a choice between Continuous AWD and Active AWD.
Continuous AWD has a viscous-type locking center differential to help distribute torque – normally configured at a 50/50 split front to rear. If wheel speed differs between front and rear, the center differential locks to help distribute power to the wheels with the most traction.
With Active AWD, an electronically controlled variable transfer clutch and limited-slip rear differential distribute power to where traction is needed. With torque typically distributed at a 60/40 split between front and rear, sensors monitor parameters such as wheel slippage, throttle position, and braking to help determine torque distribution and direct it to the wheels with optimum traction.
