To understand the new Supra’s heart, you have to appreciate what BMW did here. The B58 uses an closed-deck block and a twin-scroll turbocharger, which means it handles boost like a champ. Stock, it churns out 382 horsepower and 368 lb-ft of torque—numbers that make the Supra a genuine 0-60 monster at under 4 seconds.
But the real magic? It sounds good. There’s a deep, guttural warble under acceleration that reminds you of classic Japanese sixes, but with a German precision. It’s the kind of engine that makes you take the long way home for groceries.
And here’s the fun fact: the B58 was actually tuned specifically for the Supra. Toyota’s engineers, led by chief engineer Tetsuya Tada, demanded a unique throttle response and a more aggressive exhaust note. They even redesigned the intake and exhaust manifolds.
The “Four-Banger” Surprise
Not everyone needs 382 horses, though. Toyota also offers a four-cylinder version, the B48. It’s a 2.0-liter turbo with 255 horsepower, and it’s lighter, sharper, and—dare I say—more playful for daily driving.
This engine is the same one found in the BMW 330i and Z4 sDrive30i. It’s a little gem: punchy, efficient, and surprisingly torquey. If you’re on a budget or just want a nimble coupe without the tire-shredding drama, the four-cylinder is a sleeper pick.
Just don’t expect to win any drag races. The B48 is for the driver who values cornering over straight-line bragging rights. As one reviewer put it: “It’s the Supra for people who actually turn the wheel.”
