The displacement of the Subaru Outback is 2.5L. Displacement refers to the volume of fluid inhaled or discharged per stroke or cycle. The Outback is equipped with a 2.5-liter four-cylinder naturally aspirated engine, which is a horizontally opposed four-cylinder engine. In this type of engine, the pistons are evenly distributed on both sides of the crankshaft, moving left and right in a horizontal direction. This design reduces the overall height and length of the engine, lowers the vehicle's center of gravity, and enhances driving stability. The Subaru Outback is a model under the Subaru brand, with dimensions of 4775 mm in length, 1820 mm in width, and 1615 mm in height. The Subaru Outback is the brand's new flagship model, representing another breakthrough in craftsmanship and material quality following the Forester.

I recently helped a friend pick up an Outback, and its engine displacement is quite interesting. Currently, the main models available in China are the 2.5L naturally aspirated and the 2.4T turbocharged versions. My friend opted for the 2.4T, which feels even more powerful than the old 3.6L model. The 2023 Outback 2.4T delivers 260 horsepower, with power readily available on demand. However, for daily commuting, the 2.5L version is actually sufficient, offering 182 horsepower paired with a CVT transmission for a particularly smooth ride. There are also some hybrid versions available in North America, but unfortunately, they haven't been introduced in China. I remember the older models around 2010 had a 3.6L displacement, but those are all discontinued now. If you come across a used one, be sure to check the engine condition carefully.

Last week I test drove the Subaru Outback and specifically researched its engine displacement. The current mainstream model in China is equipped with the FB25 series 2.5L horizontally opposed engine delivering 182 horsepower, which is sufficient for daily use. The fuel cap recommends 92-octane gasoline, making it quite economical. For those who prefer stronger acceleration, there's the FA24 2.4T turbocharged version - though the displacement number is smaller, horsepower jumps to 260 with turbo engagement starting at just 1500 rpm. I've driven the older 3.6L model in Australia before, and the linear feel of the 6-cylinder engine was indeed excellent, though the new models are cleverly tuned. The standard all-wheel-drive system across the lineup is the real highlight - no matter how large the displacement, it can't match the stability of AWD, something you'll truly appreciate on icy roads.

The Subaru Outback offers a detailed range of engine displacements. The current domestic models all feature four-cylinder engines. The 2.5L naturally aspirated engine is perfectly adequate for daily driving, and it doesn't feel sluggish when overtaking on highways. For those seeking more power, the 2.4T turbocharged version is available—this turbocharged engine transforms the driving experience, making it feel like a completely different car. Last month, its composure during mountain road cornering was truly impressive. Older models also included six-cylinder versions with EJ series 3.0L and 3.6L engines, but unfortunately, these were discontinued after 2014. It's worth noting that engines of the same displacement may have different tuning across model years; for example, the 2018 2.5L model has 7 more horsepower than the 2015 version. The low center of gravity of the horizontally opposed engine is a genuine advantage, providing more stability over speed bumps compared to conventional SUVs.
