Inside Line Test of X3 35i vs 28i

Interesting. amazing that the 28i is 1 second behind. not a slouch for a 4,180 pound sav.
both cars has same tires goodyears LS, but mounted on 18 and 19 inch rims. interesting slalom and handlign numbers.

Our long-term 2012 BMW X3 xDrive35i is, to put it simply, a beast. Armed with a 300-horsepower turbocharged inline-6, our six-cylinder X3 has "more motor than you'll ever need," and that's exactly how we like things.

And while not everyone shares our penchant for "More, bigger, faster!" BMW's new base engine offering in the 2013 X3 is no slouch.

The 2013 X3 xDrive28i comes with a slick, direct-injected 2.0-liter inline-4 that's being boosted to 240 hp and 260 pound-feet of torque. This mill replaces the naturally aspirated inline-6 that also made 240 hp. The name of the game here is efficiency, and the 2013 xDrive28i returns 28 mpg highway/21 city and an EPA combined rating of 24 mpg compared with 19/26/21 from the xDrive35i.

Picking the 28i over the 35i will save you $5,000 for the 2013 model year, but what do you give up? We took one to the track and compared it with our long-term six-cylinder X3 to find out.

Comments

Acceleration: Plenty of torque down low, but a fairly lazy launch nonetheless. Plenty of gears to keep engine on the boil and smooth/rapid upshifts. Same results from Sport and manual-shift mode, as it auto-upshifts regardless.

Braking: First stop was the shortest, and the remainder were tightly grouped and slightly longer. Firm pedal and it remained so throughout.

Handling:

Skid pad: Very slight advantage in dynamic (Sport +) mode here, but still very little interference from ESC either way. Steering is precise but vague-feeling. Effort and build-up feel manufactured. Doesn't self-center the way it ought to.

Slalom: Nondefeat ESC on a BMW?! Non-linear steering response, combined with firm chassis provides a threshold that's hard to predict. Best way through was slow-in/fast-out to maintain progressive throttle seems to keep ESC at bay. Dreadful steering that doesn't provide intuitive response given the input.

Comments:

Acceleration: Holy guacamole! This was an utter surprise to me because I hadn't looked at the ungainly badge on the side of the X3 (xDrive35i). Strong AWD launch, but then at 4,000 rpm the afterburners light and the X3 really comes alive. Default/first run in Drive + Normal mode; subsequent in Sport Drive + Sport Plus. The close-ratio gearset keeps the engine in the sweet spot after each velvety upshift (with spark retard or some such) exactly at (or slightly over) redline. Holds a gear past redline (to 7,300 rpm) and also performs matched-rev downshifts.

Braking: Medium-travel medium-firm pedal never wavered. Moderate-to-light dive, straight and steady, with slight increase in distance in middle runs that disappeared by the last.

Handling:

Skid pad: Dynamic-mode (nondefeat) ESC was virtually nonexistent on the skid pad, allowing the X3 to pile on gentle-yet-terminal understeer at the limit. Good balance and tractability but no chance of rotation. Steering goes light as understeer builds (as it should). Slight difference with ESC on, where it imperceptibly bled throttle.

Slalom: Again, dynamic-mode ESC is rather lenient unless yaw and steering are crossed for too long. If this happens, the run is scrapped anyway, so it's really an "Oh sh*t" safety net. Good front-end bite and quick to react in transitions. Very trustworthy, so I was able to coax some lift-throttle rotation to snub understeer when approaching the limit. With ESC on, it used the brakes sparingly to maintain smooth arcs between cones but wouldn't allow lift-stab-lift-stab. Remarkable speed and agility for something this size.

The manufacturer provided Edmunds these vehicles for the purposes of evaluation.

to the new drivetrain in the 28i.

I drive the 35i and have to agree with the quote,

Nice article...thx for sharing. Been loving my F25 since day 1. What a beast!!!

What do you guys think about this guys comments after the article? I almost joined Edmunds Inside Line just to respond but thought better of it.

ummmm.... the 2013 Accord V6 and the 2013 Optima Turbo both trap at a higher speed in the 1/4 mile than the twin turbo 35i in this test.....

One must really ask themselves.... why have the complexity of DI, TWO TURBOS, and all the associated hardware when Honda can make a SOHC non-DI V6 perform the same.... yeah yeah, the area under the curve is what matters... except it doesnt..... Honda deserves some serious props for the genius of their V6.... 34mpg highway with a regular 6 speed auto.... marvelous...



..."...but then at 4,000 rpm the afterburners light and the X3 really comes alive..."...

I would love to see this hyperbole used when describing the 2013 Lexus ES350 do a 1/4 mile run. I am sure it would stay right there with the 35i to 100mph... yet no such hyperbole would be lauded on it....

ummmm.... Someone tell this guy the X3 is not a sedan..."hyperbole" ? He has obviously never driven a F25 before...or has confused the 35i with the 335i

An Accourd and an Optima aren't even the same type of vehicle so obviously suspekt360 doesn't have a clue. Not worth the trouble of responding.

It's curious how the same driver commented totally differently on the skidpad and slalom tests for both cars, whereas there is no difference in the cars suspension, tires, as well as break pad size, and they both have nearly identical crub weight. How does more horsepower in the 3.5i equate to such a difference in handling?
