Serious answer: It's my only car due to space constraints and it's fun to go to the road course and drag strip. I wouldn't have bought it if it couldn't be made quick (which means I would never buy the 4 cylinder).
+1

What I like about the X1, in particular the x35i is its truly a sleeper.
In every day daily driving, its very quick!

Actually, I have had a 35i loaner for the past 3 days and I feel that I can compare the two very well ( i also can compare the transmissions, having the 8 speed in our of our X3 35i with the n55+ 8 speed set up in a similar architecture. The loaner strangely was fully loaded and identical in every way to my own exempt that it was in mineral grey instead alpine weiß(both had 19' alloys, ultimate package, //M-sport, coral red leather, brushed 'aluminum', auto high beams, heated seats, however, my X1 was a victim of the 'paddle-gate' and thus does not have paddles while the loaner did). Also, my car has about 12k miles whereas the loaner had about 1300.

First there are some physical differences , the exhaust tips on the 35i are 12mm larger in diameter than those of the 28i. The tachometer on the 35i goes to 8K whereas the 28i goes to 7.5k (no difference in redline, just larger red zone) and the 35i has an oil temp gauge while the 28i has consumption. The brakes are significantly larger on the 35i. The Shifter is a more archaic and must be placed into park and stays in the selected position while the 28i's stays in the centre and can place itself into park, and is illuminated.

Second, the feels while driving: the transmissions are rather different, the older 6 speed is adequate but shifts from the paddles come after about 1/3 of a second and are sluggish at best, compared to the near DCT response and quick gear changes of the new 8 speed of the 28i and X3 35i. Several times in M sport mode I found myself waiting on the 35i to serve me a gear while I was hitting and churning past redline, sometimes even to the limiter before the gearbox would shift. What this reminded me of was Jeremy Clarkson of Top gear UK reviewing the Maserati GT MC and remarking how the gearbox could not even remember that it was a gear box, more things like cake, or a pencil (I am someone who is used to driving the zf 8speed and DCTs). The brake peddle on the 35i feels much better and is much softer and smoother with what feels like more linear braking, presumably because of the larger brakes. The gas peddle feels the same with its heavy weight and laggy, unlinear response. The 35i, being a straight 6, is perfectly balanced and there was no vibration anywhere (I drove up to about 80mph), the sound is classical and smooth and sounds like any other modern n55 BMW. The N20 is rougher sounding and in operation (not necessarily a bad thing) and there is significant turbo lag and the spool up can be felt, an heard, from 1600- 2000 rpm, the car always has a subtle buzz in the steering wheel because of the unbalanced engine architecture but is not very noticeable in the rest of the car. And yes, from start up and to about 2500 rpm, it does sound like a turbo-diesel… somehow (direct injection?). The extra weight and balance of the 35i from the 28i (3891lbs compared to 3726 and a balance of 52.1/47.9% and 50.6/49.4%, respectively) does change the agility of the car. Also, the 35i has servotronic, which my car does not. the 28i's steering is light and agile while being firm and crisp while the 35i's feels like the f25 or any other modern BMW, electronically over-boosted. Also, with the extra wight being forward of the front axle it gets more 'under-steer-y' where as the 28i is arguably front- mid engine with little weight beyond the from axle.


All things considered it is very hard to decide which I like better but i come down to taste. The price difference between the to are minor, ~45k to ~47k (28i v 35i) USD and the mileage was similar, I average with a combination of country and urban 23 and 19 mpg overall (28i and 35i). 28i is a light, agile, heavily turbocharged, wagon with its strengths in the gearbox and weight distribution. The 35i is a heavier, plowing, brute who overcomes its weaknesses with brute force and so many torques. I hope this is helpful to any people on the fence!

Regards,
Trevakun

So far, I love the handling of my Sdrive28i. It feels light and is very direct. It's as good or better than other BMWs I've owned. It's not an M-car (which I have), but it's not supposed to be. It's actually much better than I expected ... great combination of performance, handling, utility and economy!

well i guess you havent driven a bmw x1 35i with the alpina trans flash because once you drive it you will be blowen away as fast as you can hit the paddles it will shift. there is a x1 owner who has also a 2012 911 carrera 4s Porsche and he said the bmw x1 35i he has with the trans flash shifts faster and better than his all wheel drive Porsche. bam bam bam

The Alpina flash really does make the transmission into an entirely different beast. Having driven each of the cars in this example, I'd place it above the ZF in the Maserati Granturismo S, JUST below (barely, very very close) the ZF 8 speed in a F30 335i, with the Porsche PDK coming in a solid notch higher than the rest. At partial throttle it really does shift as fast as the Porsche PDK. It's only at 6k RPM at WOT with 460+lbft of torque where you can detect a slower shift. That being said though, it's not a lazy or delayed shift. The reaction is instantaneous. That is the beauty of the Alpina flash - it removes the electrical hesitation, so even at 6k RPM WOT what I am feeling is the mechanical delay of the transmission shifting as fast as the internals possibly can. And that's a nice feeling.

If you ever use the paddles, you owe it to yourself to do the transmission flash. Risk free and easily reversible, what's not to like.

I am nearing a decision on a new BMW and the 28i v. 35i dilemma is something I am wrestling with. Having a N55 motor now, I tell myself it would be hard to move over to the N20. However, having driven the N20 I was impressed and for how I drive my car currently, would certainly work. Decisions, decisions.

I think the power difference shouldn't be an issue. 28i has adequate power and better transmission. You can practically drive it in sport mode all the time (reduces performance gap) and get the same mileage as 35i.

The main difference is engine refinement. The 6 cylinder is much smoother. 28i NVH disappoints sometimes, although this happens more in regular non-sport mode and low engine rpm.

Assuming you want a loaded car (adding the xDrive, lighting and sunroof to 28i), the price difference is about $3500.

I think my xDrive28i feels a bit heavy already, I don't want a heavier car considering the overall size of the car.

The 28i is 3500lb and 220WHP.
The 28i x is 3700lb (+5.5%) and 200WHP (-9%).
The 35i x is 3900lb (+11.5%) and 270WHP (+23%).

AWD increases the crank to wheel losses by 5-20% depending on speed and clutch engagement so it feels like it's a much heavier car.

If you need AWD, 35i is the way to go. If you don't need it, the sDrive28i is a better accelerating car than the xDrive28i.

At 100+ MPH, vehicle weight matters nil and the only perceivable thing is power since the aerodynamics are the same.

I hate AWD but need it because I use it for ski trips often. Nobody wants to stop and put on chains when the sign is up.

Also, why should anybody care about 100+ MPH if they live in US? It is like saying this car feels better than the other one when you DUI!?

The reason I don't want a heavier car is not that acceleration is slow, but the overall balance and handling of the car. A Lighter car is more enjoyable, because it accelerates, brakes, and turns with less effort and less strain on chassis.

ha ha u just dont get it, the 35i has greater potential all the way around, iam running about 450hp and wider tires and rims and can beat or hang with the best sports cars the bmw x1 35i is a rare beast its a do it all suv, wagon, sedan, & sports car.

Snow tires. Plus, BMWs have fake LSDs now by using brakes.

The 35i has more power potential but it's still an open deck block. I would not run it at 75hp/cylinder even with the cast iron liner.

The 6 speed auto is built to handle 330ft/lb at the crank, anymore would be risky IMHO. S55 with its semi-closed block has much more potential and it has the DCT.

300lb of the 400lbs is engine weight that is 24 inches off the ground. It makes for a very sloshy machine no matter how stiff your suspension and makes the case for 19'. But in a straight line, no other X1 will beat you and the bigger brakes are nice.

Those aren't the real numbers for the 28. BMW underrated the 28 so people will spend another 4k to get the 35. The 28 goes like a bat of hell up to 110 which is the fastest I have driven in it. If you want more horsepower so you can brag about that is fine but the extra power serves no useful purpose.

You also lowered your car. I am sure if you hadn't you wouldn't be able to hang with the best sports cars.

It only makes sense to compare them at stock trim. If you start talking about modified versions, both the 28i and 35i could reach very high power and handling potentials, and your limit will probablly only be restricted by your bank account balance. Would that make sense if I strip the interior, add a roll cage, do a full racing suspension swap, run on race rubber, rebuild the motor and tranny, add 6 piston big brakes on a 28i and then go compare it to a 35i, or the other way around? There are tuned Honda Civics out there that could smoke a stock M5.

Plus personally, I think modifications always will affect reliability of a car. A stronger part will wear out and eventually break a weaker supporting part. It is a game of finding the weaker links, doesn't matter if it is engine mods or suspension mods. I would stay away from mods if it is my only daily driven car. Your car is the most reliable remaining stock. (of course I would totally do it if I have a weekend toy) I admired what Subaru's STi project designer said about the new 2015 STi, when asked why there was no power upgrade from the previous generation. He said there is no need to add more strain to the chasis. And that car, with the same 305 hp flat 4, bested the M235i on the tracks with the carrying over power rating.

It is not a matter of traction. It is regulation. In California when they have chain sign if you don't have AWD you have to put on chains. Highway patrol actually enforces this in mountain passes.

ha ha the 911s werent racing lol why were they on a race track, let me guess they were going to get milk for the kids, ok and the x1 28i is better than x1 35i ok fine in your world you can believe what you want.
Now in the real world me with my stock times 13.6 1/4 and para running 12.1 1/4 mile with just $2000 in bolt ons, which i just bought those bolt ons for my x1 shows clearly the potential of the bmw x1 35i. even the suspension is different from the 28i m sport to the 35i m sport for example the rear camber bolts in the 35i m sport are the same as the bmw 1m. sorry 28i

I was the second fastest car in the intermediate group at the mid ohio event with the Porsche club today. The only point by I gave all day was to this 997 gt3, which I later caught in the above video.

I ran a 1:50 with the chicane today on stock suspension. Very competitive with 911 times, and faster than most pre 991 cars.
