Billy Covington Subaru has been a major player in the automotive industry for decades, and their vehicles are known for their reliability and performance. The 2020 Subaru lineup features a range of turbocharged engines that improve fuel efficiency and give drivers more power and control on the road. In this article, we’ll take a closer look at how these turbocharged engines work and what sets them apart from other engines on the market.
Key Takeaways
- Subaru’s 2020 lineup features a range of turbocharged engines that improve fuel efficiency and provide more power to drivers.
- Turbocharged engines work by compressing air before it enters the engine, allowing for more fuel to be burned and increasing power output.
- Subaru’s Direct Injection Turbocharged (DIT) engines feature a twin-scroll turbocharger that optimizes airflow and provides more power at lower RPMs.
- The DIT engine also uses a high-pressure direct injection system that enhances fuel efficiency and reduces emissions.
- Subaru’s Boxer engine design allows for a lower center of gravity, better balance, and improved handling.
How Do Turbocharged Engines Work?
Turbocharged engines are becoming increasingly popular in the automotive industry, and for good reason. These engines work by compressing air before it enters the engine, which allows for more fuel to be burned and increases power output. The process begins when air is drawn into the engine through the air intake system. From there, it passes through a turbocharger, which compresses the air and forces it into the engine’s combustion chamber.
When the compressed air enters the engine, it mixes with fuel and is ignited by a spark plug. This creates a controlled explosion that pushes the piston down and turns the crankshaft, which in turn powers the car’s wheels. Because more air is being forced into the engine, more fuel can be burned, which results in more power output. This is why turbocharged engines are often used in high-performance vehicles.
What Sets Subaru’s Turbocharged Engines Apart?
Subaru’s Direct Injection Turbocharged (DIT) engines, which are featured in their 2020 lineup, are designed to be more efficient and powerful than traditional turbocharged engines. These engines feature a twin-scroll turbocharger, which optimizes airflow and provides more power at lower RPMs. The twin-scroll design works by dividing the exhaust gas streams that flow into the turbocharger, which allows for more efficient combustion and reduces turbo lag.
In addition to the twin-scroll turbocharger, the DIT engine also uses a high-pressure direct injection system. This system injects fuel directly into the combustion chamber at high pressure, which enhances fuel efficiency and reduces emissions. With this system, fuel is delivered in a more precise and controlled manner, which allows for more complete combustion and better performance.
Another key feature of Subaru’s engines is the Boxer engine design. This design, which features horizontally opposed cylinders, allows for a lower center of gravity, better balance, and improved handling. This is because the design places the engine’s weight closer to the ground and evenly distributes it, which improves the car’s stability and control.
Subaru’s Turbocharged Engine Lineup
Subaru’s 2020 lineup features a range of turbocharged engines, each with its own unique set of features and capabilities. Here’s a breakdown of the engines available in Subaru’s 2020 lineup:
2.0-liter DIT Engine

2.4-liter DIT Engine
This engine is available in the Ascent, Outback, and Legacy models and also features a twin-scroll turbocharger and a high-pressure direct injection system. It delivers 260 horsepower and 277 lb-ft of torque.
2.5-liter DIT Engine
This engine is available in the Forester model and features a twin-scroll turbocharger and a high-pressure direct injection system. It delivers 182 horsepower and 176 lb-ft of torque.
Frequently Asked Questions
What are the benefits of a turbocharged engine?
Turbocharged engines offer several benefits over traditional engines, including improved fuel efficiency, increased power output, and reduced emissions. They are also often used in high-performance vehicles because they provide more power and better acceleration.
What is turbo lag?
Turbo lag is a delay in the delivery of power from a turbocharged engine. It occurs when the turbocharger takes a moment to spool up and produce boost pressure. This delay can be reduced by using a twin-scroll turbocharger or other advanced turbocharging technologies.
What is a Boxer engine?
A Boxer engine is an engine design that features horizontally opposed cylinders. This design allows for a lower center of gravity and better balance, which improves handling and stability. Subaru’s Boxer engine design is a key feature of their vehicles and sets them apart from other cars on the market.
Conclusion
Subaru’s 2020 lineup features a range of turbocharged engines that improve fuel efficiency, provide more power to drivers, and set themselves apart from other engines on the market. With their Direct Injection Turbocharged (DIT) engines, twin-scroll turbochargers, high-pressure direct injection systems, and Boxer engine design, Subaru is leading the way in engine innovation and performance. Whether you’re looking for a high-performance vehicle or a fuel-efficient crossover, Subaru’s turbocharged engines have something to offer.
