What Engine Does the Toyota Supra GR A90 Have?

The heart of the Toyota Supra GR A90 is a 3.0-liter turbocharged inline-six engine, codenamed B58. But here's the twist: this isn't your typical Toyota engine. It's actually a BMW engine!

This makes the Supra GR A90 feel quick and responsive in everyday driving situations. Beyond just the raw specifications, the B58 engine is known for its robust construction and tuning potential. Many Supra owners have successfully increased the engine's power output with aftermarket modifications, while still maintaining reliability. This has made the Supra GR A90 a popular platform for performance enthusiasts and tuners. Toyota's decision to use a BMW engine in the Supra was initially met with some controversy from purists. However, most people have come to appreciate the engine's capabilities and the overall performance of the car. The collaboration between Toyota and BMW has allowed the Supra to benefit from BMW's expertise in engine design and manufacturing, while still retaining its own distinct identity. Overall, the B58 engine is a key component of the Toyota Supra GR A90's appeal. It provides a strong foundation for performance and delivers an engaging driving experience.

This allows for more precise control over fuel delivery, which can improve fuel efficiency and reduce emissions. Variable valve timing, also known as BMW's Double-VANOS, adjusts the timing of the intake and exhaust valves to optimize performance at different engine speeds. This helps to improve the engine's responsiveness and efficiency across the rev range. The engine has a compression ratio of 10.2:1, which is relatively high for a turbocharged engine. This helps to improve thermal efficiency and power output. All these features work together to create an engine that is both powerful and refined. The Supra GR A90’s engine is designed to deliver strong performance in a variety of driving conditions. Whether you're cruising on the highway or pushing the car to its limits on a track, the engine provides plenty of power and responsiveness. These specs make the Supra GR A90 a formidable sports car, capable of competing with some of the best in its class.
