New 4 cylinder Turbo vs Inline 6

Looking for opinions on the new BMW 4 cylinder Turbo on the 3 series. How do they compare to the past Inline 6 engine like i currently have on my 3281?

Nothing compares favorably to an inline six.

Reports about the 4 cylinder are not favorable compared to the 6 which is very smooth. That said most 4 cylinders I have owned were all more NVH than other engines with more cylinders. Power out of the 4 provides more low end torque (just like our 335's) compared to the 6 it replaces.

No first hand information but I do plan to drive one in the near future...

I just had an F30 loaner for a week. New engine is a blast. Yes, it is a bit gruff and nowhere near as smooth as the N52. It also is responsive as hell and a lot of fun to drive. Great engine and definitely at home in a BMW.

The four is nice if your not big into winning stoplight races, its got nice pull and its good on takeovers (I had an x1 as a loaner for 300 miles), but again you will definitely hit a wall if you step on it enough. My vote I6.

NA inline 6 is so much smoother than the F30 4 cylinder. The 6 revs nicer, and sounds much better when your hitting higher RPMs. On idle, the 6 sounds more refined. The 4 sounds like a diesel which is not a bad thing, if it was a diesel. However, the turbo engine has more pickup at lower RPMs, just sounds like it's working hard. To it's credit, the 4 cyl turbo engiine gets better city, and highway mileage. My preference would be the 6 cylinder.

There was a discussion here (or on the F30 forum) 2-3 months ago; search for it.

Unless you are looking to keep the price down on a new build, I would probably skip it. The straight sixes are like butter and sound much better and you are not gaining big MPG numbers by going with the 4.

Being relatively new as well, I would be wary of 1st year teething problems.

This is not the first year for this engine. It has been in the Euro X1 for a year. And yes, you are gaining big numbers in fuel economy. 23 mpg city vs 18 in the E90 328i. I get 21 mpg in my E90 328i MT and if the N20 gets at minimum 23 I'd be happy. 25-26 seems more realistic.

I have ridden the F30 twice now and would second this opinion. It's definitely a good engine and is a respectable replacement for the N52. It delivers a similar driving experience with better gas mileage.

The steering is what I'm not very fond of, though I have yet to drive a sports package equipped car. I don't suppose that will change the steering feel any though.

After having an F30 328i as a loaner, I'm also impressed with the new 4 and would consider it as a replacement for my E91 when the time comes - but only if BMW makes the MT available on the F31.

It should be obvious, N20 is not as smooth as N52, but the potential of tuning will make this engine way faster than N52 (being lighter), not to mention better fuel economy.

IMHO, the power is not the problem on new F30, but steering feel is the biggest problem.

I prefer the I6 but don't mind the N20.

There is plenty of power with the N20, I have not heard anybody say otherwise, what people are complaining about is the noise, and the smoothness.

Had one out today and would take it over the old N52 anyday! Not as smooth, but it is very smooth at the bottom end, way more torque than the N52 - get's a bit 4 cylinder rough at higher RPM's, but is worth it for the torque at the bottom end.

Also, for about the same price as guys spent to get an extra 5hp out of the N52, you can add 40! These things with a $500 tune will come close to keeping up with a stock 335!

It does all that and will get you 5+ mpg better - N52 will be missed but also forgotten!

Let them put some mileage on it, and after we'll see what will be missed and what forgotten.

We can argue all day long, sign petition to BMW etc; BMW won't bring back I6 on lower models, at the end of the day it's CAFE/EPA regulation puting strangehold on all car mfgs, keep building gas guzzling cars, get ready to pay fine (in the form tax per unit sold). the latter for BMW will cost alot unless pass to consumers, which would makes BMW cars less competitive pricewise. If you want I6, then you need to get 335i etc.

PS: I have a feeling even 335i in 10-yr will have tax on gas guzzling ala M5, yep thanks to EPA/CAFE; but on the other hand maybe we need to be more responsible to younger generation.

The steering is a major, major disappointment. EPS feels like a half baked concept to me, good in theory but doesn't translate well to the real world.

Best we can do for the younger generation it to slow down of its production. In my lifetime the world population is more than doubled. I smell trouble.

Meh. I'm sure there won't be any problems with the first years of a new BMW turbo charged engine.

Said no one at all.



PS: I6 FTW.

Its more like 15 hp 12 trq not 5 hp (see AA tune). Of course the N20 is and will be a lot more easy to tune due to the turbo. I have owned both turbo and non-turbo vehicles and experienced a lot of headaches with turbo motors, specially when tuned.
