The B58 is the only turbo BMW I want. I like the BMW Z4 M40i and the 340i. I am a huge fan of BMW’s N/A engines having owned everything from M20,M42,M30,S38,M88,M54,S54, S62, and N52. I currently have my 06 330i sport pack manual with the 255hp N52 as a daily driver and it is extremely reliable. The S54 M Roadster and S62 E39 M5 are for special days. I am glad BMW is redeeming themselves with the engine but they still have work to do in the styling department to bring back the magic of the good ‘ol days. These newer engines can’t provide the beautiful sounds of the older N/A engines, but that’s why I will always keep an N/A BMW in my garage.

So I have had my 2008 335i since 2011 and it has now done 170k. I have religiously followed the service regiment, and addressed every single issue as soon as they appeared. What did I change during this time other than standard things like fluids, filters and pads? 1. High-pressure fuel pump, changed once. 2. Water pump, went after about 155k 3. flushed transmission once, and changed mechatronic sleeve 4. changed spark plugs twice 5. coil packs once. 6. Front shock absorbers once 7. Charge pipe That's it. Take care of the car, and the car takes care of you. Leaks? Only once from the front shocks right before they went. Sitting inside driving, the car looks and feels like new. No rattles, everything is tight. It is such a treat to drive, love the hydraulic steering rack, so much better than the newer electric ones!

Great video Mark. Loved the detailed history of the modern BMW 6. Toyota really pushed BMW on the latest 6 to build it reliably. Interesting was that Toyota was flying engine bolts to Japan to test the strength.

[@bubuski]

I’m curious to read a good source on Toyota’s actual involvement. BMW and Toyota agreed on the feasibility study to define a sports car joint platform in 2013 and the OG B58 came out in 2015, not quite enough time to develop or fully revamp an engine but the B58TU then launched in 2018 which went on the Supra.

I had the B58A in my old 440i and it felt sluggish over the N55 I had in my old m235. I ended up getting the MPPSK installed and that engine just came alive. Truly loved every moment of it, with a huge bump in torque putting a smile on my face. Just traded it in for a 540ix with the B58C and just counting down the days until I can get it tuned. It's really not that bad, but once you fully experience what the B58 can do you can't go back. I'm excited to see how much more power this B58C will be able to put down over my old B58A.

These cars aren’t too bad to be honest, once you upgrade all the plastic parts it’s good, it’s not like they break every week lol That’s why I tell people it’s maintenance over modifications. Because you don’t know how the previous owner treated the car. You have to do oil change and all fuilds, vacuum lines so you don’t have boost leaks, spark plugs, ignition coils, and fix any type of leak coolant or oil, fix it asap. And you can’t expect a car not to break if you’re abusing it everyday, come even a lambo or Ferrari will break, take care of your car and it’ll take care of you.

Great review. I’ve owned BMRs with the N54, N55 and S55 engines. The N54 also has carbon buildup on the exhaust valves that have to be cleaned periodically. The S55 is a top end engine. Dual coolant systems, 5-6 separate radiators, dual HPFP’s. The only warning for mod folks is you’ll have to replace the original crank hub or it might spin and destroy your engine.

[@chrisbradley3224]

Your breakdown is good and info is pretty accurate, but your potential horsepower numbers are way off. There's no way you can make 1000 hp on N54 or 700 hp on N55 or 1300 hp on S55 even close to reliably without MAJOR modifications like a completely built motor. If you look on the forums, cars tuned that hard are not very reliable. I am not sure about N54 but I know N55 really shouldn't go past 450 whp if you want a reliable car. S55 shouldn't go past 600. Also, on S55 the crank hub can spin (especially if tuned) and charge air cooler cracks and leaks frequently.

Toyota didn’t take just the B58 specifically, they took the entire Z4 drivetrain/chassis as Toyota had nothing in their portfolio. So Toyota had to take all engines which are/were available in the Z4, so the Supra not only has the B58 but also has the B48 from BMW

[@AvengerAngel]

A breath of fresh air on BMW stepping up reliability. In general, turbos provide additional power in smaller engines and thus are a great marketing attribute for folks who prefer high performance cars over economy. The EPA places so much pressure on manufacturers to decrease fuel consumption and carbon, which is not what people who love high performance are necessarily interested in and as a result, manufacturers have also made detrimental changes to lighten vehicles with plastics which are intolerable to conditions of performance cars in the long run. In turn, plastics are compromising reliability (longevity).

It’s called innovation of the limited life span of product to keep demand rolling. If the market accepts the short life span the why stop there? The profit margins can just keep growing which is what really matters.
