X3 Xdrive 28i quicker than the X1 Xdrive 28i?

I was just checking out the recently updated BMW USA website, and noticed that the X3 Xdrive 28i 0-60 time is rated at 6.2 sec. How could it be possible for the 4150lbs X3 be a tenth quicker than the 3726lbs X1 28i Xdrive? They both use similar tires too right?

Something doesn't make sense. Same transmission and engine.

400lbs is a huge weight difference. I doubt the gearing on the X1 is any less aggressive. The X1 28i Xdrive's 0-60 time falls 0.3 second behind a similar weight 328i wagon also. I know the drag coefficient of the X1 is 0.32, which is no worse than any sport sedan's. Now it appears to be the slowest N20 28i of any model line up, also slower than the heavier 328i GT and 528i.

I think it's just marketing from BMW's standpoint, we all know that they underrate most of their cars anyway, and they don't want the more expensive X3 being slower than the X1. The same weirdness is present on the 35i versions as well. There is no way the X3 is faster - every road test is showing that the X3 loses to the X1 in the 1/4 mile.

But out of all of them, the X3? It is 400 lbs heavier and looks like a brick. Now all a sudden with a mid-life face lift, it is quicker than my X1, without any mechanical upgrade? Just how?

It's not. Could even just be a typo, BMW's website is terrible. The configurator shows the wrong pictures for the options half the time.

Now I am tempted to seek out a X3 at the red light to settle the score lol

Of you changed the axle ratios in the x3 it's quite possible that it could get to speed quicker and just suffer in the top end. Simple drag racing way of getting there quicker, also really cheap

The X4 specs are even better:

Quote:
Drivers with sporting ambitions will appreciate the top-of-the-line X4 xDrive35i. Its 3.0-liter inline six conjures up maximum output of 300 hp between 5,800 and 6,400 rpm and peak torque of 300 lb-ft (400 Nm) at 1,200–5,000 rpm. That's enough to power the X4 xDrive35i from 0 to 60 mph in just 5.2 seconds. The 240 hp turbocharged 2.0-liter four-cylinder powering the BMW X4 xDrive28i produces peak torque of 260 lb-ft (350 Nm) and a 0 to 60 mph time of six seconds flat. Both engines are mated to BMW's 8-speed Steptronic sport automatic transmission.

While I'm more inclined to agree with the posters who claim it's a marketing ploy, I'd be interested in knowing the final drive or 'revs at 60' of the respective vehicles. It may be a matter of an advantage in gearing, or even when or how many shifts are required to achieve 60.

It could very well be the tires, this same issue exists with the 228 manual and 328 manual with the 328 being faster due to standard tires. Same engines and same gear ratios.

If X4 is 6 flat, X3 is 6.2 and X1 is 6.3 then it's almost guaranteed to be marketing ploy.

It's such a small variance that there is no way anyone could prove it.

Only other thing could be variations in the torque curve to produce more torque at lower RPMs which would lead to slightly faster times.

Car and Driver's X1 28i Xdrive long term test posted a 6.0 sec 0-60 as new, and usually they could drop that number at the 40K miles mark. Their quarter mile number was 14.6 sec @ 95mph, 0-100mph 16.4 sec. Their X3 number was at 6.2, 14.8@93 mph, 0-100mph 17.8 sec. So basically the real world straight-line numbers are very similar, but the X1 should be ahead at the 1/4 mile drag strip. On the twisty road it is where the X1's hydraulic power steering shines. If I wanted better straight-line numbers and open highway pssing power, I would have gotten the 35i. But with the same chasis and suspension, the 35i is not as balanced as the 28i on the twists, and I find it carrying over too much speed into tight corners for its own good, while the 28i could be driven at a more flat-out manner. What bothered me was that most media sources will never do their own road tests like Car and Driver. Rather they would simple quote what BMW has claimed on their offical website.

BTW, I guess some cars are made better for launching. Like the new 428i, Car and Driver posted a 5.3 sec 0-60mph as their test result...stunning result. But its quarter mile and 5-60mph rolling start is just 0.4 second quicker than the X1 28i, meaning the 4 series coupe is optimized for launching from a well planned full force take-off. In real life street start or on the freeway, it is not noticeably quicker.
