F32 4-series has grown taller in 3 months?

Toshi · 10-04-2013, 03:46 AM

When BMW released the press kit in June, the height of 4er was 1,362 mm (53.6 in).
And now she’s got 15 mm taller. What happened with her?

The press kit (pdf here) stated “a roofline that now runs 16 millimetres lower than before (1,362 mm)” in page 5, and the specification (page 27 & 36) also shows the height = 1,362 mm.
But I recently found the technical data on the web shows the height = 1,377 mm (54.2 in).

FWIW when I go on the bmwusa sote it says the xdrive 435 is ~3700+ lbs which I believe is incorrect as well

Wait until you see a 4 series x drive if you want to see a high car...............

Just got this email from BMW AG...

Dear Toshi,

thank you for your e-mail!

The data in the press kit is correct.
We will check the data in the other source and have it corrected.

Best regards from Munich

Were the two figures both of the same line? My first thought was maybe it could have been an M Sport figure before with the slightly lower suspension.

Yes.

19 wheels as apposed to 18 would get you that 1/2 inch difference!

Wheel size doesn't change ride height.

Check the press release and the web site in the 1st post.
Both tech specs are on the same 17" rims. Only the body height is different.

Think about it!! The overall diameter of the wheel and tire has to be exactly the same in order for it NOT to make a difference.

gonein10 · 10-04-2013, 11:22 AM

I don't see any info in regards to the overall diameter of that 17 rim with 50series tire.
width of the rim with same size tire will make a difference

In most cases the overall diameter stays the same (..i.e...larger rim, lower profile tire......smaller rim, higher profile tire). Going from 18's to 19's or from 19's to 20's doing really affect overall diameter.

Yes maybe 1mm or so difference in diameter, but not a dimension that is going to change the height of the car by any significant amount.

19" wheels are not bigger than 17" or 18". Tyre aspect ratio is changed to get a very similar rolling circumference and wheel diameter.

Also the idea that a bigger wheel (rim diameter) fills the fender gap is just an optical illusion, not due to a different wheel diameter.

Correct. Otherwise every car would have to have different speedo calibrations etc.

Elk · 10-04-2013, 01:16 PM

Yup. As well as different suspensions, etc. to account for the bigger and smaller wheels.

The overall diameter on all wheel/tire packages is therefore the same.
