335xi is faster than the 335i - BMW 3-Series (E90 E92) Forum

UdubBadger · 06-08-2008, 09:25 PM

... dispite being 200lbs heavier.

why is that? and why isn't that true for the 328i/xi?

TheAcAvenger · 06-08-2008, 09:30 PM

hahaha. threads like this is why it took you guys so long to get your own forum.

It's faster 0-60 because the torque on the 335 is enough to cause traction losses when you're trying to come swinging out the gate. Thus, the all wheel drive minimizes wheel spin and gets the car off the line faster. Thus, it has a faster 0-60 time because generally, the most important factor of a 0-60 time is a launch (which is while 60-100/120 and 1/4 mile ET/Trap are how most people really determine how fast a car is).

In the 328.. well, you guys dont have as much wheel spin off the line so the awd isn't going to give you that big of an advantage. There's not really much wheel spin to be minimized going from an i to an xi.

Not to mention that 0-60 times are all really bogus calculations anyway. Edmunds can go out there and run a 5.5 and Road and track might get a 4.8 on the same day. 0.2 seconds on a manufacturers 0-60 time should be taken with a grain of salt.

"faster" is a very flexible word

quicker off the line.

hmmmm i always thought thats what the DTC was for... not AWD but I guess that makes sense.

sparkyg · 06-08-2008, 09:51 PM

I think the xi may be slightly faster 0-60 but overall i has better balance and less drivetrain loss.

This is all on dry roads of course. Add water and I'd put the xi in front every time.

FirstClass · 06-08-2008, 10:13 PM

Everyone always talks about extra drivetrain loss, but doesn't the cluch disengage the front axle from the power over 100ish? So really the i is faster in the midrange, but it's the same up top (weight isn't relevent there, all drag and power) and the xi is faster at launch.

my SA told me it was something like 40F/60R power unless x drive detected slipping then it changes to 50/50.

not sure about it at or over 100mph though.

ShiraiwaRiku · 06-09-2008, 12:15 AM

because N54 engine is a lot powerful than the N52 engine..

therefore 335i tends to have less grip on the launch than the all wheel drive 335xi..

but after 100km/h 335i will catch up like one mean motha facka XD

I was under the impresson that AWD split was more like 5/95 until the xdrive detected spillage then it went 50/50.

Can anyone confirm?

X drive on the 335 is infinitely variable (meaning 0-100% on whatever end *corner* has traction). Under full traction conditions, it's biased towards the rear (roughly 36% F / 64% rear).

Apparently above 160Kph (100mph) there is no power delivery to front axles.

There is a bit of drivetrain loss. The front end power is only disconnected at the transfer case. The front axles, diff, and prop shaft (driveshaft between front diff and transfer case) is still being spun by the front wheels when power is directed away from the front.

What DTC does is limit the power going to the wheels (either through ABS or the DBW throttle) to maintain maximum acceleration. So, if you are driving all 4 wheels (theoretically 75hp per wheel vs. 150hp per wheel in RWD) you can use all of the power without DTC interfering because of wheel spin.

i read that edmunds is more accurate b/c they do it from a standstill whereas road and track times are sometimes based on a rolling start. whether this is true i am not sure but it would make sense since road and track times are usually lower than edmunds

More often than not, a rolling start with a turbo AWD car won't be as fast as start off the line.

Most car company's will send a slighlty tweaked car to magazines for review. you will find that especially with the 335 reviews. I think it was either car and driver or road and track that had a situation where the car provided by BMW was significantly faster then the loaner they got from someone who worked for the magazine.

xi > i

xi FTW!

DTC is going to reduce power to the wheels to reduce slip. Xi is putting down max power to more wheels to reduce slip. Max power > reduced power!

wrong... the 335xi is a tad QUICKER, but the 335i is FASTER!
