That's cos mags from USA seem to consistently achieve much quicker times than mags from Europe. Just like the argument between consistently fast times achieved by Autozeitung compared with others such as AMS or Auto Bild.
As u said, AMS did a 5.1, so I trust AMS more as their approach is more methodical.

Launch mode or not it's still the same thing. If u're going to hurt the components then they're going to be hurt.
Launching a autobox car with 2k rpm is much kinder than dropping the clutch for a manual car at 2k rpm (some cars might stall if only 2k rpm). That's cos all u're doing to the auto is to heat up the fluids inside the torque converter. As long as u let the fluid cool down in between each run, u won't do much harm (unless of course u launch the car like that every day).

The run shown on the clip may not be the actual run used for timing.

Official figures is 0.6s difference, the margin increases the faster u go due to stronger top-end on the N55. On the other hand there may be no margin at all if it's 0-60 or 0-80 due to traction issues.
If this 4.7s is recorded w/rollout then it's consistent with 328i as the other test (328i) did a 5.5s with rollout (i.e. 0.7s difference between the 2).
As said previously, if u always do Autobahn speeds then 335i it is, otherwise anything below 180-200km/h the 328i is more than enough.

Still can't get my head around buying a new 4-cyl engine in a bimmer.

Guessing the x-drive will be even slightly quicker.

The term more than enough is based on personal preference. To me more is never enough....

I just don't get it. I was hoping this would be the video to settle but alas, no. These car companies are either using roll outs or some strange launch control instead of just giving the consumer actual 0-60 times. Its as if they're trying to get the most controversial number, not the most accurate.

0-60 tests are designed to get the best results not the most repeatable results or the results you and I would get. They find the optimal revs that won't spin the tires and with an AT brake torque to that point and dump the brake and mash the throttle at the same time. With a MT they find the right revs, dump the clutch and mash the throttle. They also often correct for humidity and elevation.

We spend a lot of time here gnashing our teeth over 0-60 times but what's relevant for most of us in the real world is the feel we get in the seat of our pants. Nothing more.

Maybe. Better traction but more weight.

Exactly! And I find my F30 way faster than my ex F10(both N55), maybe it's the MT box and off course the weight.

Did 200kmh already(125mph) an hour ago(no or almost no traffic) in 6th from 80mph---> 125. It's quick.

It's so much more torquey than that F10. Wow.

On a related note, it is totally LAME that you have to get the 19"s to get the staggered 255s in the rear. I mean I have staggered 255s in the rear on 17"s right now!

+1. but those 19" also add a good amount of weight where you dont want it...

On the roof? You're doing it wrong.

I have two thoughts on the 225 rears.
1) Many folks that really care will be going with aftermarket wheels anyway.
2) If the damn car had an LSD, 225's might actually be enough

Agreed. 0-60 launch techniques should be reproducible by different drivers, but the times will always differ. Waiting till wheelspin passes and the car grips and starts moving will give you a faster time than when you actually mash the throttle.

To me, it felt great. Perhaps it is not as empirically "fast" as my current 135 but that 8 sp ZF box really is a game changer. To me the 335 had the 50-80 mph response of the 135 DCT car I test drove. Gave it an inch of throttle ( it appeared to downshift 2 gears) and that was all I needed to make my decision.

0-60 times a a snapshot reference. Its not a range you drive the car in most of the time. The 328 is plenty quick the 335 is just quicker and smoother.

[catalyst]

I have to say, this video gets me excited for a possible power "bump" with the F32 next summer (2013). Crossing my fingers that something comes along....as I'll be returning my E92 335i at that point.

I would really enjoy a 340i or some equivalent

Why not? Most of BMW's motor racing heritage (& success) come from 4 cyl motors. Whether it's the dominant F2 motor, to the most powerful ever F1 engine (according to BMW Motorsport's then boss, it's so powerful it can destroy the test bench), to the all conquering S14 engine, they're all based on the M10 4-cyl block. In recent years, BMW won successive WTCC titles with the N45 engine.

It will, traction is a big issue.

528iX N20


535i N55


Just compare the 0-50km/h & 0-80km/h times, plus the 528iX is heavier than the 535i.

They do not roll the car. 0-60 is from a dead stop. Same with Inside Line for 0-60 times:

http://www.insideline.com/features/h...nd-trucks.html

Road & Track does a 1 foot roll but they subtract the time for that 1'. Not sure about Motor Trend.

Kamigawa - I also agree with you! I have a X6 3.5 bigger than your X3 and on manual I manage 5.8-5.9sec on manual.

Are you really comparing a car that weighs 500 lbs less in terms of performance? LOL The knowledge on this forum amazes me at times.

As far as 0-60 times are concerned, different situations will get different results which is why 0-60 times are not a good way to judge performance. Any sort of incline change, tire change, traction issue, style of launching and temperature will all have to do with 0-60 times. Trap speeds at the end of the 1/4 mile are the only relevant ways in comparing 2 vehicles performance in that regard, the 335i is 5-6 MPH faster than a 328i (which is a huge difference).
