Does the Supra have a B58?
Yes—the current Toyota GR Supra uses BMW's B58 engine in its 3.0-liter turbo inline-six variant, while the 2.0-liter model relies on BMW's B48 turbo inline-four.
Context: the Supra’s engine pairing
The GR Supra was developed in collaboration with BMW, sharing powertrain technology across both brands. In the current generation, the 3.0-liter version uses the BMW B58 inline-six turbo engine, while the entry-level 2.0-liter uses the BMW B48 inline-four. All current Supra models are equipped with an automatic transmission; a manual option has not been offered.
3.0L turbo inline-six (B58)
The 3.0-liter variant is the performance-focused option and relies on BMW’s B58 engine family. It benefits from the turbocharged inline-six configuration and is paired exclusively with an automatic transmission in the GR Supra lineup.
2.0L turbo inline-four (B48)
The 2.0-liter model uses BMW’s B48 turbocharged inline-four. It provides brisk performance and efficiency, and, like the 3.0, is mated to an automatic transmission in the Supra lineup.
Engine options at a glance
Below is a quick snapshot of how the engines line up across the current GR Supra lineup.
- 2.0-liter turbo inline-four (BMW B48) — entry-level engine
- 3.0-liter turbo inline-six (BMW B58) — performance-oriented engine
In short, the Supra lineup centers on two BMW engines: the B58 for the 3.0 variants and the B48 for the 2.0 variants. The B58 is not used in the 2.0 model.
Summary
The GR Supra’s engine strategy hinges on BMW’s two-powerplant family: the B58 for the 3.0 inline-six and the B48 for the 2.0 inline-four. The B58-equipped 3.0 model represents the performance spear of the lineup, while the 2.0 offers a more accessible entry point. Both configurations are paired with an automatic transmission, and no production manual option is currently offered for the GR Supra.
