In 2015, the BMWB58 turbocharged straight-six engine went into production. The N55 was replaced by the B58, which debuted with the F30 340i.
Following the B38 and B48 engines, the B58 is a member of BMW’s new modular engine family, which includes engines with 500 cc (30.5 cu in) of displacement per cylinder.
The B58 engine, which is found in the 340i and 440i, was designated one of the world’s ten best engines in 2016, in 2018, in 2022 (M240i), in X3 and X4 M40i, in Z4 M40i, in 2019 (X5), and in 2020 (M240i) (M340i).
The high performance variant of the B58 engine is the S58, which debuted in early 2019.

Performance of the 335i and 340i
This issue will also be covered fairly quickly. The main comparison of 335i and 340i performance will be in the Tuning section. The 335i and 340i actually give remarkably similar real-world performance. Due to a slight increase in power and torque, the 340i appears to be slightly faster. The 340i has 320 horsepower and 330 torque, while the 335i’s N55 engine produces 300 horsepower and 300 torque. The B58-equipped BMW 340i vehicles also benefit from a marginally improved power curve.
From the factory, 0-60 times are very similar, hovering around 5.0 seconds. Times for the quarter mile are in the mid-13s at 105 mph. There are various factors that influence these timings, and different testing yields different findings. AWD or RWD, transmission, altitude, road conditions, tires, and drivers are some of the key variables. The 335i and 340i both have similar performance straight out of the factory.
Performance & Technical Specification Summary for the BMW 340i F30
From 2015 until 2018, this BMW 3 Series 340i was manufactured. It belongs to the F30/F31/F34/F80 generation of the 3 Series. The 2012 BMW 335i has undergone a facelift. It’s a midsize car with four doors and a front engine that seats five people. This 340i’s turbocharged 3 Liter 24v Inline 6 gasoline engine (BMW B58B30) propels it to 62 mph in 5.5 seconds and a top speed of 155 mph with 322 horsepower. Its average fuel economy is 31.8 mpg, and despite having a curb weight of 3538 pounds, it can go 504 miles before needing to refuel. It has a choice of an 8 gear automatic transmission or a 6 speed manual transmission. There is 17 cubic feet of luggage room and a 1070 lb. payload limit. Most recent update was on January 2, 2019.
What is the BMW 340i’s 0–60 time?
While the earlier 340i has a catless downpipe, intake, and its own E50 tune, the M340i comes with a catless downpipe, charge pipe, and setup.
Does the Supra’s engine fit the 340i as well?
The S58 actually displaces somewhat less than the B58, which has a bore and stroke that are stated as 84 and 90 mm and 82 and 94.6 mm, respectively. This indicates that while the S58 has nearly flawless 500-cc combustion chambers, the B58 has a total displacement of 2,998 cc.
335i or 340i, which is superior?
While the BMW Z4 roadster’s brother employs a similar basic drivetrain, Toyota launched the Supra last year with a B58 six that had been modified to produce 335 horsepower. This year, the BMW Z4 M40i and the 2021 Supra’s B58 both produce 382 horsepower and 368 lb-ft of torque.
What distinguishes the 340i from the M340i?
The old S55 engine from the BMW M4, which is no longer functional, is actually the one in the M2 Comp. Oddly, the BMW M140i, a vehicle that is older than the M2 Competition, has a brand-new engine, the BMW B58, which also powers modern vehicles like the M340i and X3 M40i.
Which BMW engine is the most dependable?
The subject of how long an engine will last is never easy. There is no correct response, although the B58 should generally last as long as you’re willing to keep up with repairs and routine maintenance. The internals and design are strong enough to travel more than 200,000 miles.
What type of engine is the B58?
The B58 engine, which is found in the 340i and 440i, was designated one of the world’s ten best engines in 2016, in 2018, in 2022 (M240i), in X3 and X4 M40i, in Z4 M40i, in 2019 (X5), and in 2020 (M240i) (M340i). The S58 engine is the more powerful variation of the B58 that was introduced in early 2019.
How durable are B58 engines?
The B58 has the same direct fuel injection, single twin-scroll turbo, variable valve timing (referred to by BMW as double Vanos), and variable valve lift as the N55 (called Valvetronic by BMW). The bore and stroke are 82 mm x 94.6 mm, and the redline stays at 7,000 rpm (3.23 in x 3.72 in)
B58 has a single turbo or two.
N55 against B58 (M135i vs M140i) (M135i vs M140i) Technically speaking, N55 is an open deck while B58 is a closed deck, and there are many more variances as well. B58 is water-air charge-cooled, while N55 is air-air intercooled. Despite the fact that both engines are 3.0 single turbo 6 cylinder machines, very few parts are interchangeable.
The B58 is there on the M2?
As you can see, the B58 is finally starting to make progress. Up to 5800 RPM, it produces a huge amount more power than the S55, and at 2500 RPM, it produces over 100 HP more. The only speed range where the S55 is currently outperforming the B58 is between 6000 and 6600RPM, and even then, only by a maximum of 17hp.
How many HP can B58 support?
With the exception of the radiator problem, the B58 has shown itself to be largely reliable, with very few instances of crank sensor and VANOS actuator problems being documented on this site. Anecdotally, N55 is more trustworthy
Are there B58s in Supras?
On paper, the B58 should be as strong and durable as, if not better than, the N54. However, without a newer turbo, the single turbo will probably limit its potential (s)
Is the S55 superior to the B58?
Despite having the same engine, they produce varying amounts of power. It produces 335 horsepower (250 kilowatts, or 340 metric horsepower), together with 369 pound-feet (500 Newton-meters) of torque, in the European Supra. In contrast, the M440i’s version has 369 horsepower (275 kW or 374 metric horsepower) and 369 lb-ft of torque (500 Nm)
Is N54 or B58 better?
The updated 3.0 liter B58 engine from BMW will power the new 540i, 740i, and other vehicles. A new version of BMW’s well-known B58 engine, which will power several sub-M performance cars, is currently being prepared.
What distinguishes the B58 from the S58?
Austria’s STEYR – At this lovely town dating back to the 10th century, BMW has a creative way of reminding staff working in its engine plant that precision is a way of life and that the gasoline and diesel engines manufactured here are meticulously benchmarked by rivals.
N55 or B58, which is more dependable?
Full Bolt-Ons for the 335i vs. 340i But the 340i’s B58 engine is the more powerful one. While the N55 335i’s maximum power is roughly 400–425whp, a stock turbo 340i can be pushed to about 450–500whp. Since the F30/F32 335i uses the EWG turbo system, you should stick with it if performance is your main priority.
