Engine Specifications of the 2015 Subaru BRZ

The 2015 Subaru BRZ is equipped with a 2.0-liter naturally aspirated horizontally opposed (boxer) four-cylinder engine. This engine is part of Subaru's FA engine family, specifically the FA20 variant. The horizontally opposed design, also known as a boxer engine, is a signature feature of Subaru vehicles, offering benefits such as a lower center of gravity, which enhances the car's handling and stability.

Key Features of the FA20 Engine

  • Displacement: 2.0 liters (1,998 cc)
  • Configuration: Horizontally opposed (boxer) four-cylinder
  • Valvetrain: Dual overhead camshafts (DOHC) with four valves per cylinder
  • Fuel Delivery: Direct fuel injection and port fuel injection (Toyota D-4S system)
  • Compression Ratio: 12.5:1

This engine is designed to deliver a balance of performance and efficiency, making the 2015 BRZ an enjoyable car for both spirited driving and everyday use. The high compression ratio contributes to its responsive throttle and energetic character. The combination of direct and port fuel injection, known as the Toyota D-4S system, optimizes fuel delivery for various driving conditions, enhancing both power and fuel economy.

Power and Performance

The 2.0-liter engine in the 2015 Subaru BRZ produces around 200 horsepower (147 kW) at 7,000 rpm and 151 pound-feet of torque (205 Nm) at 6,400 rpm. These figures allow the BRZ to offer brisk acceleration and a thrilling driving experience. The engine's high-revving nature encourages drivers to explore the upper reaches of the tachometer, where it delivers its peak power.

  • Horsepower: 200 hp (147 kW) @ 7,000 rpm

This transmission provides smooth and responsive gear changes, allowing drivers to enjoy the BRZ's performance without the need for manual shifting.

Both transmissions are designed to complement the engine's characteristics and enhance the overall driving experience. The manual transmission provides a more direct connection to the engine, while the automatic transmission offers a more relaxed and user-friendly experience.
