Hey there, gearheads and Subaru enthusiasts! Today, we're diving deep into the heart of the 2021 Subaru Legacy Premium – its engine. This is where the rubber meets the road, quite literally, and understanding the engine is key to appreciating this solid sedan. We're going to explore everything from horsepower and torque to fuel efficiency and common issues. So, buckle up, and let's get started!

Unveiling the Powerhouse: Engine Specifications

The 2021 Subaru Legacy Premium comes equipped with a dependable 2.5-liter SUBARU BOXER® engine. This engine is known for its smooth operation and inherent balance, thanks to its horizontally opposed cylinder configuration. This design allows for a lower center of gravity, contributing to the Legacy's stable handling. Now, let's break down the core specifications:

• Engine Type: 2.5-liter DOHC SUBARU BOXER® 4-cylinder
• Horsepower: 182 hp @ 5,800 rpm
• Torque: 176 lb-ft @ 4,400 rpm
• Fuel System: Direct Fuel Injection
• Transmission: Lineartronic® CVT (Continuously Variable Transmission)
• Fuel Economy: 27 mpg city / 35 mpg highway / 30 mpg combined

These numbers paint a picture of an engine that prioritizes fuel efficiency and a balanced driving experience. While not a powerhouse, the Legacy Premium's engine provides ample power for everyday driving, including city commutes and highway cruising. The CVT complements the engine's characteristics, offering smooth and seamless acceleration.

The SUBARU BOXER® Advantage

So, what's the big deal about the SUBARU BOXER® engine? The horizontally opposed cylinders offer several benefits. First, as mentioned, the lower center of gravity improves handling and stability. This design also contributes to reduced vibrations, resulting in a smoother and quieter ride. The SUBARU BOXER® engine is a hallmark of Subaru engineering and is a key factor in the brand's reputation for reliability and longevity. It is known for its durability, making the Legacy a good choice for those seeking a car that can withstand the test of time and mileage.

Another advantage of the Boxer engine is its inherent balance. The opposing pistons naturally counteract each other's movements, which reduces vibrations and improves overall refinement. This translates to a more comfortable and enjoyable driving experience, especially on longer journeys. The engine's design also contributes to its efficient use of fuel, helping to achieve those impressive MPG figures. The direct fuel injection system further enhances fuel efficiency by precisely delivering fuel to the cylinders, optimizing combustion.

Performance and Driving Experience

When it comes to performance, the 2021 Subaru Legacy Premium offers a comfortable and composed driving experience. Acceleration is adequate for most driving scenarios, allowing for easy merging onto highways and passing slower vehicles. The CVT, while not providing the same feel as a traditional automatic transmission, is optimized for fuel efficiency and smooth operation. The Legacy Premium isn't designed to be a sports car, but it offers a confident and predictable ride that inspires confidence. The all-wheel-drive system, standard on all Legacy models, provides excellent traction in various weather conditions, making it a great choice for those who live in areas with snow or rain.

Handling and Ride Quality

The Legacy's suspension is tuned for a balance of comfort and control. It effectively absorbs bumps and imperfections in the road, providing a smooth ride for passengers. The steering is light and responsive, making the car easy to maneuver in both city and highway driving. The all-wheel-drive system enhances handling, especially in challenging conditions, by constantly monitoring and adjusting power distribution to the wheels that need it most. This improves stability and helps the car maintain its intended course.

The overall driving experience is one of refinement and ease. The cabin is well-insulated from road and wind noise, creating a quiet and relaxing environment. The Legacy Premium is a car that you can confidently drive for hours without feeling fatigued. The vehicle's emphasis on safety, with its standard EyeSight® Driver Assist Technology, further enhances the driving experience by providing additional protection and peace of mind. Features like adaptive cruise control and lane keep assist make long journeys less stressful and help to prevent accidents.

Fuel Efficiency and Practicality

Fuel efficiency is a key consideration for many car buyers, and the 2021 Subaru Legacy Premium delivers respectable numbers. With 27 mpg in the city, 35 mpg on the highway, and 30 mpg combined, it offers a good balance of performance and economy. The CVT transmission plays a significant role in achieving these figures, as it optimizes engine speed for maximum efficiency.

Cost of Ownership

Fuel costs are an important part of the overall cost of ownership. The Legacy Premium's fuel efficiency helps keep these costs down. Subaru's reputation for reliability also contributes to lower long-term costs. Regular maintenance, such as oil changes and tire rotations, is essential to keep the engine running smoothly and to extend its lifespan. Subaru provides a comprehensive maintenance schedule in the owner's manual, and following this schedule is critical for ensuring optimal performance and preventing costly repairs.

The Legacy Premium's interior also contributes to its practicality. With ample space for passengers and cargo, it's a great choice for families or anyone who needs a versatile and comfortable sedan. The trunk offers plenty of room for luggage and other items, and the rear seats fold down to provide even more cargo space. The car's overall design is focused on providing a comfortable and practical experience for the driver and passengers.

Common Issues and Maintenance

Like any car, the 2021 Subaru Legacy Premium may experience some common issues. Here are a few things to keep an eye on:

• CVT Issues: While the CVT is generally reliable, some owners have reported issues. Following the recommended maintenance schedule is crucial.
• Electrical Problems: Occasionally, some electrical issues may arise. If you experience any electrical problems, it's best to have them diagnosed by a qualified mechanic.

• Filter Replacements: Replace the oil filter, air filter, and cabin air filter regularly. This helps to ensure that the engine is getting clean air and that the cabin is free of dust and allergens.
