Everyone is entitled to their own opinions, but nobody that has driven that car would say it performs like the 325. It blows the NA engine out of the water. Every car magazine ranks the two 335 models as nearly identical in performance. If the manual is the deal breaker then so be it. As far as longevity, I would say that with all the HPFP issues the i has, the d looks like the reliability champion so far. We'll see in a few years, but I can't imagine an engine with an RPM sweet spot of 1/3rd redline would not outlast one that is "rev happy". For resale, the fact that the used d's are so expensive on the used market compared to the rest of the 3er's leads me to believe resale will be just fine. Unless of course diesel fuel gets to be much more expensive than premium. I do agree with you in that I wish BMW would bring the 20d over for the smaller vehicles. I would die for a car with 328 type performance that gets 50mpg or more. I think that the greenies fearing diesel and enviro policies in several states kept this from happening. |

325 comparison is overblow, yeah. How about it has the fuel economy of the 325, with the power of the 328, for the cost of the 335i?
Yes, the rpm sweet spot is down (just as it is with the 335i) but I would worry about the peak cylinder pressures as much as the rpm. That is more likely to impact longevity. Those with 300,000 mile 3.0 X5s on this board haven't been shy of using rpms. I don't think running a BMW inline six up through the rev range compromises its reliability.

That is a really good way to describe it. Even if you were more generous and said it has the economy of the 325, with the power of a 330, for the cost of a 335i, it still wouldn't be a good deal, imo.

I wasnt aware a 325 got 40mpg on the highway. I also wasnt aware that the 328 matched the 335i 0-60. The d does both(OK, .1 sec slower than the 335i).
And I don't care if it's a Chevy, a BMW, or a Ferrari, running an engine balls out at high RPM's constantly is going to wear it out faster than running it slower. That is just common sense. Why do you think rental cars run like hell after 50,000 miles? I'd like to know the service history of dealer loaners since they more than likely get driven harder than people's personal vehicles. I would be willing bet a bunch of money that the vast majority of 300,000 mile X5's were not redlined very often. Of course if you lease, it doesnt matter and becomes someone else's problem...... :-) Maybe it's just my driving style, but I feel the d fits me better than the i. I like having tons of power available at low rpm's so I dont HAVE to rev it all the way up. In real world day-to-day driving how often do you really need or want to run 8000 rpm? |

I literally floor my e36 325i multiple times per day and I now have over 320,000 miles on it. As long as you have the right amount of the correct oil in the engine, I really don't think high rpm's have that much affect on a BMW 6 cylinder engine. Now, some rental-car special, i.e. Malibu, Fusion, Altima, etc may not handle it as well.

I got this from the fuel economy website link I provided earlier.

Thanks for proving my point with the above data.

It's kinda like those Republicans you spoke of. Their opinions on Obama (like a choice in a different driving machine) would be far different if it wouldn't cost them the a future election. Some people as usual without accurate knowledge, just have to follow the Jones.

I don't have a concern over running my BMW gasoline engines to redline most times I drive them, after they are properly warmed up. It has not resulted in increased oil consumption or engine wear. If you read posts by wallyx5, he discusses his 300,000 mile 3.0 X5 that he regularly runs at high speeds. These engines do much better with that use than they do on short trips and at idle. If your 35d works for you, that is fantastic. They are great engines. My only comment would be that if you like to take advantage of the low speed torque, and keep engine rpms down, and always have throttle response available, then that is not so much a diesel characteristic as it is a turbocharged engine characteristic. Your diesel just happens to be a turbocharged design. My 535i has the same characteristics, but with the added bonus that I can rev it if I want to. It has a six speed manual, and I can pretty much shift it 1-3-5 or 2-4-6, it has far more gears than it needs in daily driving, given the available torque just off idle.
