X5 35d vs. X5 3.0si - Acceleration Tests!

Last week I was fortunate enough to have both the gasoline and diesel variants of the X5 in my driveway. Armed with my G-Timer, I ran acceleration tests on both.

The tests were done by simply flooring the vehicle -- no tricks like pre-loading the torque converter or holding the brake pedal down. This is real world acceleration. The transmission was in DS mode (A/C off, DSC off). The altitude was about 25 feet above sea level, the air temp about 85 F, and each had 1/4 tank of gas. The road was straight and level.


MPH____35d____3.0si

0-10____0.68_____0.40
0-20____1.58_____1.48
0-30____2.75_____2.65
0-40____3.92_____4.30
0-50____5.55_____6.10
0-60____7.28_____8.42
0-70____9.40_____11.30
0-80____12.00____14.42

The turbo lag is quite obvious off the line with the diesel, but once it hits about 35 mph it pulls ahead and never looks back! By 80 mph, the 3.0si is nearly 2.5 seconds back (that is huge in a wheel-to-wheel race).

Note: BMW quotes 0-60 as 6.9 (35d) and 7.8 (3.0si).

Without holding the brake pedal down and preloading the TC what kind of a drag was thatseems too objective to me. After 80 I suppose you ran out of road or spotted a Chippie Nice test, mirrors what I would think would happen. Good on 'ya as they say in Oz.

I tried it with preloading the TC. Unfortunately, the 35d launched off the line... and then the transmission completely bogged down and choked (a transmission protection mode?). The 0-60 with the loaded TC on the 35d was 7.57 seconds. It is better simply flooring it.

My road is a couple miles long, but my testing equipment only runs 1/4 mile before it shuts off. The 3.0si never hit 90 mph within the 1/4, but the 35d did.

the 4.8 gasser would be more fair of a performance comparison

Well, both tested models are 3.0-liters. And, they are within a few thousand in MSRP. The V8 is much more powerful (and it simply drinks gas). The V8 is still the sports car of the bunch -- the 3.0-liter gas just seems sadly outdated.

But V8 is much closer to 35d than 3.0si
The good thing about 35d is that it really performs like 4.8, but sips less fuel than any X5

Imagine if you chip this thing

The way I see it...

X5 xDrive30i - Obsolete/Superseded
X5 xDrive35d - Everyman's X5
X5 xDrive48i - Enthusiast/Sport Variant
X5 M - Egotistical/Boastful Variant

- Mike

FYI

When I powerbrake my 35d, I get the RPM's up around 3K. The launch is very hard & fast; almost feels like the vehicle is being distorted. I never felt any bogging or stuttering as mentioned above, just a real hard launch. I did this with my wife in the car at one point & she yelled at me because it snapped her head back so hard. I'll have to time it at some point to check the 0-60. Would be nice if Mike - Emission would time this as a comparison.

I guess once a gearhead, always a gearhead.

I don't doubt you. However, I was satisfied with my "real world" testing.

Oh, the X5 35d is back with BMW. I have this in my driveway now (a 6-speed manual, of all things)... I think it eats BMWs as a snack.

Why? The injection is post-combustion, within the exhaust....

There are quite a few good tuners in US who will be able to create couple of options for diesel owners
It's just a matter of time

I suspect there are limits as to how much fuel/exhaust the SCR catalyst can handle. Now, whether pumping more fuel/exhaust through it will damage the catalyst, or just increase emissions and possibly throw a engine check light, I don't know (I'm not sure if there is an NOx sensor after the catalyst).

But the system seems to be rather closely integrated into the engine operation, including a starting prevent interlock if the system is out of fluid.

But I'm sure the tuners are looking at their options.

whats wrong with Kleemann?

your right its just matter of time (how long though?) until tuner companies begin offering something for urea injection cars.

Oh, nothing wrong at all, it's great company
But you said they thought it was not possible to tune this car
