Not really supra related but still something cool to check out, BMW's new engine S58

- 3.0 liters, but not exactly the same as the B58. The S58 has a slightly larger bore and shorter stroke (84.0/90.0) compared to the B58 (82.0/94.6). Displacement is technically down five cc, and it’s still an undersquare engine. Theoretically the new engine should have room for bigger valves, better breathing, and should be more rev-happy, but we’ll learn more in time.
- 7,200 RPM redline, up from 7,000 on the B58.
- Twin-turbo, as opposed to single on the B58. Confusingly, the B58 is a twin-scroll turbo, with two separate sets of exhaust runners independently running into one turbocharger. BMW calls this “TwinPower Turbo.” The S58 also splits the exhaust, but half the cylinders run into one single-scroll turbo and the other half into another. BMW also calls this, and I cannot stress how dumb this is, “TwinPower Turbo.”
- Compression ratio down to 9.3:1 versus the B58’s 11:1. This sounds bad to people obsessed with naturally-aspirated engines, but makes sense to those familiar with running boost.
- 473 HP and 442 lb-ft of torque in base trim.
- 503 HP in Competition trim, also with 442 lb-ft of torque.
