bmw b58 vs n55

It appears BMW is showing their commitment to the new modular B series engines. Normally, we look at what has remained the same Engine block now uses a closed deck block design from the open design found on the N54/N55. It runs a higher compression ratio so is more efficient and it has a bigger low end/mid range punch. Increased power and torque without sacrificing fuel economy, Improved comfort in the passenger compartment, Engine displacement has increased from 2,979 cc to 2,998 cc. BMW’s latest engine release is designated as the B58 engine in the 6-cylinder version. by Kerr » Sun Aug 26, 2018 8:10 pm, Post I find that hard to believe. The F30 330i will come wtih the B46. Would be suprised if BMW had not improved the product TBH. However, to deal with the situation that the turbo still needs to be cooled after engine is turned off, an extra dedicated electric pump is added to the turbo unit to tackle this issue. It appears that power/torque for the 330i version of the B46 are going to be similar to the outgoing N20, however it might be under-rated and more than likely it will boost fuel economy by around 10% similar to what was achieved when they went from the N55->B58, Correct. It still amazes me how BMW is able to make its turbocharged I6s feel naturally-aspirated. There's a lot more potential to mod this engine because it's built to hold diesel pressures.

We can see these consistent, but often conflicting, goals in engine designs from VW/Audi and their MQB platform, to Jaguar’s Ingenium engines to BMW’s new B-Series engines. The N55 sounds better. BMW put a focus on engine weight distribution. The BMW N55 engine was something of legend.

All orders placed both on the phone and online are still being dispatched as normal. I just hope that BMW has fixed the rear-mounted timing chain problems that occurred in the M47 (and to a lesser degree in the M57 and N47).

BMW S55 vs S58 Reliability. How else does the N55 w/ MPPK differ from the non-MPPK version of N55 and/or B58? It was easily one of the best engines on the market throughout its entire tenure, regardless of what else was on the market. It feels better to rev harder.

Thanks for the write-up, I was curious why BMW designed a completely new engine to replace one that's not all that old. VANOS is responsible for timing adjustment, and Valvetronic is used for control the lift height of the valves and acts as the throttle body. However, it copes with higher cylinder pressures better especially important since the bones of the block will be shared with diesel platforms. by Pigelton » Sun Aug 26, 2018 7:35 pm, Post by GeeDee » Mon Aug 27, 2018 11:22 am, Post Come join the discussion about Bimmerfest events, production numbers, programming, performance, modifications, classifieds, troubleshooting, maintenance, and more! However, we are all a bit spoiled and don’t want to give up any power. In 2010, the 335i received the updated N55 engine followed by the B58 in 2016, however, the model was rebranded to the 340i.

The closed block design is stronger, but it is heavier, more expensive and restricts coolant flow requiring upgraded coolant system. The heat management module on the B58 is mechanically powered directly by the crankshaft through a serpentine belt. I think intake, firing order and turbo play their part as well.

Despite both engines being 3.0 single turbo 6 cylinder units, very few parts are shared between them. I've heard the economy and emissions are unchanged from stock.

Bringing the BMW community together. ↳   In Car Entertainment, Communication & Sat Nav, ... er-engine/, engine you have under the hood, remember at Alex’s Autohaus we are The boost threshold on both engines is pretty much identical, and before achieving boost pressure make very similar torque outputs: There are several good reasons for this. M140I SE / MG, Oyster, Orbit Grey / Manual / Heated Seats / Adaptive, The n55 won awards as well, in fact bmw win with most models of their straight 6. Also personal opinion.
