WHAT YOU SEE BEFORE YOU

is the heart of a Subaru. The

innovative

,

horizontally opposed Subaru Boxer engine. Available in Outback vehicles as

a

smooth

250-hp 6-cylinder, a

potent

250-hp intercooled and turbocharged

4-cylinder, and an energetic 168-hp

naturally aspirated 4-cylinder. It

is unlike the more conventional engine layouts of other manufacturers in

that its cylinders are aligned on a single, horizontal plane. This remark-

ably

efficient

configuration results in a powerplant that is

compact

,

lightweight and extraordinarily well-balanced. Now with Electronic

Throttle-Control (ETC) drive-by-wire technology for more precise response,

the Subaru Boxer engine delivers outstanding

power

and performance.

Subaru Boxer Engine

The Subaru Boxer engine’s layout allows it to be placed

lower in the chassis, reducing vehicle center-of-gravity for
well-balanced handling.

Aluminum-alloy block and cylinder heads help to reduce

weight, thereby improving overall vehicle balance without
sacrificing strength or durability.
