Hi guys,

Next week I will be buying a BMW aproved used 4 Series Gran Coupe M-Sport. That’s decided. However I’m torn between the 430i or the 430d, I have already worked out I can’t afford the 440i so don’t even go there! They are very close price wise, the 430i being slightly cheaper, but not by much.

The petrol is a fraction slower, but sounds much nicer. The deisel sounds good for a deisel, but I still think the petrol sounds better. However the petrol is only a 4 cylinder, where as the deisel has that mighty straight 6.

I do about 12k miles a year which isn’t a lot. But I’d be keen to know if anyone has any real world MPG of eithe car.

Help me out guys, I can’t decide.

[since you indicated 430i] - I would assume your engine is B46/48] - that being said - don't let that 4-cylinder engine fool you ... it WILL give you a kick in the @ss

how long do you intend to keep the car for ?

Do you mean the 4 cylinder is a good engine?

I’ve heard good things about it, and on some YouTube videos I’ve watched of it, it sounds pretty good too! Some nice exhaust notes and even a little bit of poping.

However, I’ve had a straight 6 in my old E39 520i (2.2) and I know how sweet an engine it is. So I really do want that straight 6 awesomeness, it just comes at such a price in the form of the 440i. The 420d is much more affordable. But you lose the sound:-(

I expect I will keep the car for 2 years.

What would you do?

Why not a used 435i?

Because gas is more expensive than diesel in the UK.

Considering that he's looking at the 430i, that's not relevant. Did you even read what OP wrote?

I sure did, a 435i is obviously going to be worse on gas than a 430i. Two extra cylinders tends to do that.

Personally I would choose the 430i if you absolutely want a brand new car.

However, if you want to go for a used car and you are concerned about power, I would also go for a used 435i with CPO. It's a lot more fun, you get extra goodies here and there on the car and it opens more possibility if you want to mod it later..

If we're speaking about 430i B46/48 based - absolutely. I certainly enjoy mine. Its VERY responsive [ECO mode aside, although it does improve gas/mileage quite a bit]. In Sport/+ you certainly hear occasional burbles/pops [sometimes hard enough to rise your eyebrows], and I really like the tone it picks up in the sport mode. Efficiency wise - well ECO does it super well; there is a thread about it somewhere here with some guys reporting on 430i consumption, including myself.
