what cars have the b58 engine

[DelTyler]

The BMW B58 engine is found in a wide range of models from BMW, Toyota, and the revived Supra. Key BMW models include the 40i variants of the 3 Series (G20), 4 Series (G22/G26), 5 Series (G30), 6 Series (G32), 7 Series (G11/G12), X3 (G01), X4 (G02), X5 (G05), X6 (G06), X7 (G07), and the Z4 (G29). The Toyota Supra (A90) also uses a tuned version of this engine. This 3.0-liter turbocharged inline-six is praised for its robust power and smoothness.

The B58 is a technical masterpiece. It features a closed-deck engine block (where the top of the cylinder block is a solid piece, increasing strength for high boost pressures), variable valve timing (VALVETRONIC), and a twin-scroll turbocharger. This combination delivers immediate throttle response and a broad, flat torque curve. Its reputation for reliability is a significant step up from its predecessor, the N55.

Here’s a quick overview of some popular models and their B58 outputs:

Model	Horsepower	Torque (lb-ft)	0-60 mph (sec)
Toyota GR Supra 3.0	382 hp	368 lb-ft	3.9
BMW M340i (G20)	382 hp	369 lb-ft	4.2
BMW X5 xDrive40i (G05)	335 hp	331 lb-ft	5.3
BMW Z4 M40i (G29)	382 hp	369 lb-ft	4.4
BMW 540i (G30)	335 hp	332 lb-ft	4.9

When considering a used car with the B58, look for models from 2016 onwards. While generally reliable, it's wise to check service history for common issues like coolant leaks from the radiator hoses or the auxiliary coolant pump. For a balance of performance, luxury, and modern tech, a B58-powered car is one of the smartest choices in its class.

If you're looking for a sweet spot of power and reliability, you can't go wrong with a B58. My cousin has an M240i, and that thing is a rocket. It’s not just in the big, expensive SUVs. You’ll find this engine in the 3 Series, 4 Series, 5 Series, and even the Toyota Supra. Basically, if it's a BMW with a "40i" badge, it's got the B58. It's the engine that made me finally understand why people love inline-sixes.

From a technical standpoint, the B58's application is broad. Beyond the core BMW lineup (3-Series, X5, etc.), its use in the Toyota Supra is a major endorsement. This joint development ensured Toyota's stringent reliability standards were met. The engine's modular design also allows for different power outputs, from 335 hp in base models to 382 hp in M Performance versions. This flexibility is why it's so widely used across sedans, coupes, and SUVs.

As a daily driver, the B58 is fantastic. We have an X3 with this engine, and it's perfectly smooth for school runs but has plenty of power for merging on the highway. It's in a bunch of BMWs that are great for families: the X3, X5, and 5 Series. Even the smaller X4 and the sporty Z4 have it. You get that luxury feel without the high maintenance of a full M car. It’s the practical performance choice.

The B58 engine is a cornerstone of modern BMW performance. Key models start with the 2016 340i. The current M340i sedan is a benchmark, and the X3 M40i is arguably the best sporty SUV on the market. Don't forget the Toyota GR Supra, which is essentially a BMW powertrain in a Toyota sports car. For enthusiasts, the B58 is significant because it's highly tunable, with many examples easily exceeding 500 horsepower with basic modifications. It's a modern classic.
