Evolution of Supra Engines
First Generation
The first Toyota Supra debuted in 1978. It featured two engine options. The 2.0 litre engine was the smaller variant, while the 2.6 litre engine provided more power.
Both engines were naturally aspirated. They focused on reliability and efficiency rather than high performance standards in production. This set the stage for future developments.
Second Generation
In 1981, Toyota released the second-generation Supra. The engines saw an upgrade in displacement and power output, changes that define the model year and generation, resulting in higher hp.
The base model had a 2.8 L inline-six engine with hp, new interior, and wheels for this generation. This engine produced around 145 horsepower, a significant increase from the first generation.
Third Generation
The third-generation Supra came out in 1986. This model introduced turbocharged engines for the first time.
Two main variants existed: a naturally aspirated 3.0 L inline-six and a turbocharged version of the same engine. The turbocharged variant produced up to 230 hp, marking a major leap in performance for the model year and generation.
Fourth Generation
The fourth generation began in 1993. It featured even more powerful engines and advanced technology.
Toyota offered both naturally aspirated and twin-turbocharged versions of the 3.0 L inline-six engine. The twin-turbo version of that model year could generate up to 320 hp, making it one of the most powerful cars of its generation.
Fifth Generation
The fifth generation launched in 2019 after a long hiatus. It continued to build on its predecessors' legacy with modern engineering, wheel advancements, and increased hp year after year.
This model used a BMW-sourced turbocharged inline-six engine, producing about 335 horsepower. The collaboration between Toyota and BMW set new standards for performance and reliability in the model year with kw and ps.
