2nd consecutive Wards 10 Best Engine award for BMW B58 3.0-liter engine.
10th Wards 10 Best Engine award for BMW Turbo 3.0 liter inline 6-cylinder.

Woodcliff Lake, NJ – Jan. 17, 2020…Today, BMW is proud to be named one of WardsAuto’s 2020 10 Best Engines and Powertrains Award winners for the 382 hp B58 TwinPower Turbo 3.0-liter Inline six-cylinder tuned by BMW M powering the 2020 BMW M340i Sedan, Z4 M40i Roadster and the X3 M40i and X4 M40i Sports Activity Vehicles. The latest iteration of BMW’s iconic six-cylinder inline engine produces 382 hp @ 5,800 – 6,500 rpm and 369 lb-ft of torque at 1,800 – 5,000 rpm. Performance and efficiency are not mutually exclusive as this six-cylinder version of BMW’s modular family of engines allows the M340i xDrive Sedan to accelerate from 0 to 60 mph in 4.1 seconds while still returning 30 mpg highway.

This updated award winning 3.0-liter inline six-cylinder engine features an aluminum crankcase and cylinder head. A new single Twin-scroll turbocharger with an integral, compact, steel exhaust manifold and impellers that weight approximately 25% less than those of preceding models, builds boost pressure more rapidly. Fuel is supplied by means of new High Precision Injection technology which allows injection pressures up to 5,076 psi. The current version of M TwinPower Turbo technology also features VALVETRONIC fully variable valve control and Double VANOS variable camshaft control.

Accepting the award on behalf of everyone at BMW who has worked tirelessly and passionately to bring the new engine to production was Ralph Mahler, Head of Product Planning and Strategy for BMW of North America. “The inline six-cylinder engine has been the heart and soul of the Ultimate Driving Machine for over eighty years.” said Mahler. “Every new updated version continues to improve the engine’s refinement, smoothness, power delivery and efficiency; all traits which are valued by our customers today and without doubt for many more years to come. We are extremely grateful and thankful for this recognition by the WardsAutos jurors.”

BMW’s inline six-cylinder passenger car engine history began 87 years ago with a 1.2 liter 30 hp version powering the BMW 303 sedan. Today, as one of the most versatile engines in the modern BMW lineup, the 3.0-liter inline six-cylinder engine configuration can be found powering vehicles from almost every BMW model line, with versions from 335 hp up to 503 hp.

“We tested this B58 inline six-cylinder turbo a year ago in the larger X5 and it won, with 335 hp.” said Tom Murphy, WardsAuto Managing Editor. “Now, just a year later, it comes to us in the all-new 3-Series, which is quite a bit lighter, with an extra 47 hp. The B58 was great then – it’s even better now. Stretching its legs, the M340i exhibits a glorious, throaty exhaust note, especially when cycling through gears with paddle shifters. This engine is remarkably flexible, great for daily driving and thrilling under a heavy foot.”

You beat me to it, LOL.

Congrats to BMW. I would like to see a more rigorous comparison of engine-only characteristics. This is, after all, an engine comparison. It should not be influenced, as it is, by vehicle and transmission pairing.

For example:
- power to weight
- power to displacement
- brake specific fuel consumption
- brake specific CO2 output
- novel technology (induction or exhaust, material choices, manufacturing process technology)

No mention about supra is one thing, but where is the m240i??

The winning engine is the B58B30O1. The press release calls out all four vehicles it is available in.

Even though it burns oil right from the factory?

Really? First I have ever heard of it and I drive an M340 like a mad man.

The most underwhelming award but for a great reason: B58 is a fantastic engine.

Funny how the B58 gets so much more publicity since it was put in a Toyota Supra. M dept obviously didn't want to give away their best, obviously.

The real winner is the S55 but we'll just keep that our little secret.

That motor is a monster and that's expected, it being the successor to the S55. It's only naturally it's going to evolve into being more resilient and better performing.

When BMW tune it for the G82 M4, it's going be roller-coaster fast but it's a highly complicated motor, I would hate to own one out of warranty.

Cool the n54 was also an award winning engine and ended up being an unreliable maintenance nightmare like most of their newer engines, I doubt this will be any better.

N54 was also BMW's first production turbocharged engine in decades. They had an n55 which was reasonably reliable and b58 looks like it has many kinks on the n55 worked out. It has a mechanical water pump now, for example.

Putting the new 382hp B58 in the M240i would be something good to consider

I am surprised, I never owned one that gave me engine trouble in all honesty. Change the oil every 4000-5000 miles and do maintenance on it before you are supposed to do them and you should have no issues unless you had bad luck and got a lemon (that does happen though unfortunately)..

Anyone know what the internal differences are between this high output B58 O1, the lower output B58 M1, and the original B58 M0?

I've put 175,000 miles on my n54. Wouldn't hesitate to get a b58 powered vehicle as it's successor if the n54 ever stops pulling its weight.

Until the exhaust cam snaps in half.

I never had any major issues with my m54 in my 330i with 175k and it's still going. Never had issues with the n54 in the 135i with over 120k when I sold it. Now it's too early to tell with my s55 now but it's been trouble free. All three vehicles have and had mild tunes. Maintenance is key and just don't beat the hell out of them. Plain and simple. BMW has been awesome to me.

Factory Ow-20 oil is too thin especially if your vehicle is tuned. I had the same issue but switched to 5w-40 Liquimoly and the issue went away.
