BMW X1 LWB: What does the increased length translate to?

4.5 inches. That’s the length of a wallet most of you carry in your pocket. It’s three table tennis balls lined up together. It’s the height of a can of Coca Cola. And that’s precisely how much BMW stretched the wheelbase of the X1 to create the first LWB entry-luxury SUV with a combustion engine.

The extended wheelbase strategy is obviously doing wonders for BMW India’s numbers as they sold their highest ever in the first half of 2026 – 8571 units, of which LWBs contribute 52 per cent. Apart from the 2GC and the M cars BMW doesn’t sell a regular wheelbase sedan in India and with LWB versions of the next-gen iX3 and iX5 already confirmed for China, there’s nothing stopping BMW from extending their LWB-only sedan strategy to the SUV segment. But first the X1 LWB has to click with buyers.

The key question then, what does 4.5 -inches get you inside the car? I brought along my inch tape measure to find out.

BMW X1 LWB design

The first point to note is that all the stretching happens aft the B-pillar. Visually, the rear door and rear glass area look larger than the regular wheelbase – but this is a detail one can make out only when looking at it very closely. Whether it’s the 5 Series, 3 Series or now the X1, BMW’s design team have ensured their LWB cars and SUVs don’t look awkwardly proportioned; the design is seamless. To make it look more expensive BMW have swapped the gloss black window surrounds with chrome on the LWB. That apart and the 18Li badge on the boot, there is nothing else to differentiate the two SUVs cars visually. Until you get inside…

BMW X1 LWB interior and space

Up front the space, the tech, the layout remains the same in the front. There is a minor difference in the dashboard trim between the two versions, but you would need a very sharp eye to spot it. One change that is immediately noticeable is the panoramic glass roof. It is considerably longer, as you would expect, but unlike the openable sunroof in the regular wheelbase, the LWB gets a fixed glass roof. Thankfully, it comes with a fabric cover that shields your head from the midafternoon sun shade. The screens remain the same: a 10.7-inch infotainment display and a 10.25-inch digital instrument cluster integrated into the BMW-typical curved display. The lack of physical buttons for some key functions, however, remains irritating.

It is at the rear where the differences are substantial. Boot space has increased from 476-litres in the regular wheelbase SWB to 540-litres in the LWB, and you most definitely certainly don’t need a tape measure to appreciate the extra knee room and the additional support under your thighs. That said, we had one handy, so we measured the rear benches of both X1’s wheelbases. Here’s what we found.

With the front seat adjusted to my driving position (I am 5-foot 9-inches), the distance between the front seatback and rear cushion was a full inch more in the LWB. With the front passenger seat moved all the way forward, as you would sit when being chauffeured, the difference increased to 3.4 inches. Push the front seat all the way back and the LWB has 3.8 inches more room than the regular wheelbase – more than enough so you won’t scream at the person sitting in front. The rear seat’s thigh support in the LWB measures 18 inches – an inch longer than the regular wheelbase Headroom is unchanged and not a concern in either version, there’s plenty.

There is more to the rear than just simply extra legroom and thigh support. BMW has fitted the LWB with what it calls ‘Comfort Seats’, which use softer foam than the regular seats for added comfort. The difference is immediately noticeable and will be appreciated by anyone spending long hours in the back. Like most BMWs, however, the rear still misses out on sun shades. BMW also appears to have abandoned the locally made, rather basic-looking removable shades it introduced with the 5 Series. So, when the sun comes blazing through, you’re largely left to fend for yourself. Fortunately, there is plenty more to like.

BMW X1 LWB comfort, ride and tech

The suspension on the standard X1, while deemed comfortable, was tuned to give the SUV more agility, less body-roll and the handling characteristic that BMWs are known for. That philosophy has been ditched for the X1 LWB and the car’s suspension is tuned more towards comfort. The result is an improved ride quality, very noticeable when you hit bad roads. In the regular wheelbase there’s a certain sharpness when you hit bumps and ruts and you could feel the lateral and side-to-side movement of the cabin, which becomes tiresome after a while. The LWB’s suspension does a much better job of swallowing potholes and rumble strips that have come to characterise our city’s roads and passengers are well isolated. The comfort levels come very close to that of the X3 that sits a segment higher.

On the dynamics front the LWB has to deal with an additional 180 kilos and the softer suspension has increased the body-roll by a noticeable amount – a compromise most people would happily accept. Unlike the rear seats, the front still has Sport Seats, which means its bolstering keeps you in place when you corner hard.

The features list remains unchanged - a 12 speaker 205W Harman Kardon audio, 360-degree camera, adaptive LED headlamps, digital and smart key which can be shared between up to 18 users, front electric seats with memory linked to the ORVM as well, 8 airbags, level 2 ADAS, and 1 month free trial of the digital premium which comes with a 1 month free trial. It adds features like welcome light animation, more ‘My Modes’, junction view and functionality of certain apps you use on your phone in your car’s screen. To extend it, you have to pay a subscription fee of ₹5000 + tax annually which is the same as on the regular wheelbase. This list is the same as on the SWB.

BMW X1 LWB performance

Floor the X1 LWB and it squats on its rear suspension – partly due to the softer suspension and party due to the eagerness of 18 more horses.

The LWB is only available with the petrol 1.5-litre, 3-cylinder engine with the 7-speed DCT and in the LWB-tune it makes 154bhp and 230Nm. The power figure is similar to the Mini Countryman C though the torque is 10Nm less.

Compared to the regular wheelbase, the extra horses drops the 0-100kmph time by 0.4 seconds, taking 9.9 seconds in our tests. Not that you will notice the difference on your daily commute but kick-down on an empty stretch of road and you will notice the difference particularly when the rising pitch of the groan of the 3-pot does result in a touch more on- road performance. The silver lining has a limit, and in this SUV it is the lack of paddle shifters – a feature taken out to save on cost with the assumption that people buying a LWB only want more comfort related features (then where is that rear sun shade, BMW?)

BMW X1 LWB verdict

In the first half of this year the iX1 LWB accounted for 60 per cent of all X1 sales, which itself is the best-selling model for BMW in India. Clearly buyers want space and the brand known for ultimate driving machines is doubling down on comfort as they chase the number 1 position in India’s luxury car market. Going forward the petrol X1 will only be available as a LWB while the diesel will continue in the regular wheelbase. Don’t ask me why, because I haven’t yet been able to figure out why the LWB 5 Series doesn’t get a diesel. BMW officials do say that if there’s enough demand they will put the diesel into the LWB X1. To which I can only say – how can there not be demand! You do lose the X1’s dynamic flourish but you gain noticeably better ride comfort and considerably more interior space. And I expect BMW to be aggressive on pricing, the ₹50.9 lakh ex-showroom price of the regular wheelbase going up to between ₹52-53.5 lakh, a price we think buyers will be happy to accept as they stretch out in the back seat.
