BMW M135i vs BMW X1

What's the difference?

To answer the question of whether it matters that the new 1 Series is no longer rear-wheel drive, I say no it doesn’t. It may not be as romantic on the absolute limit, but it is better in every measurable way, and still feels distinctly BMW despite moving to the conventional layout of its rivals. 

Be sure to check out Mal’s video review from the 1 Series launch last December:

This new BMW X1 feels like it's been built by a team of parents because it’s one of the most practical and easy to use small SUVs my family and I have ever lived with and, trust me, they’ve seen a lot of test cars come through the Berry garage.

We loved the roomy interior with high ceilings, the clever storage everywhere from the giant door pockets to the floating centre armrest up front and big boot for our pram.

Entry and exit is easy through the tall and wide doors, something my back was thankful for every time I had to put our baby into her car seat.

Driving is easy, with great visibility and the engine that comes in the xDrive20i M Sport makes this X1 sporty and fun to pilot, too.  

The only drawback is the price, it's a bit expensive but at the same time you are getting a high-quality feeling SUV.

Yes, that kidney grille is rather large. If you want everyone to know you drive a BMW, you’ll love it. If not, get used to it. The X7, recent 7 Series update and upcoming 4 Series suggest they’re only going to get bigger. 

Nose aside, the 1 Series hatch has always had a distinctive, long-bonnet profile, which has generally been attributed to the rear-drive layout. Despite the move to a transverse engine, the new one is actually very close in proportions when compared side by side.

It’s just 5mm shorter in overall length and 13mm taller, with body width being the most notable change at 34mm wider. 

The key difference is that the front and rear wheels have been moved further back into the body, because of said engine layout change, and to make more back seat space in the rear.

Surprisingly for a model aimed at a younger demographic, the new 1 Series interior design isn’t quite the same step forward as the recent G20 3 Series.

It’s a cut above the X1 and X2 SUVS the new 1 Series shares its underpinnings with in terms of the shapes used, but is still classic understated BMW. 

However its headline act is the Live Cockpit driver display on both models, which gives you fully digital instrumentation and replaces traditional analogue gauges once and for all.

This current generation of X1 arrived in late 2022 and finally looked more like part of the BMW SUV family with tall and boxy styling rather than the sleek, but raised hatchback it seemed to be before.

My test car had 'M Portimao Blue' metallic paint - a flattering hue that showed off the X1’s lines as you can see in the images.

I like the X1’s oversized grille which suits the angry looking front bumper that comes with the M Sport inclusions, but balanced by pretty headlights.

Inside, the X1 xDrive20i M Sport is modern and minimalist in design. I like the floating centre armrest in between the driver and front passenger and the way it creates a feeling of more space and adds more storage.

The double screens are nice, but we’re seeing this same design and tech now in budget cars such as the Chery Omoda 5 and Haval H6. BMW needs to be even slicker and more stylish if it wants to maintain its edge.  

If you like your SUVs sporty looking then check out the BMW X2, X4 and X6. These are coupe style SUVs (but with four doors).

With my modest 172 cm height, I never had any trouble with the old model, but the new 1 Series is a bit more more spacious by all the important measures.

The back seat base and backrest are a bit flat though, which is probably to help the backrest fold almost flat, but probably not very supportive during hard cornering.

There's also no centre armrest in the back or cup holders, but you do get bottle holders in the doors.

You also get two ISOFIX child seat mounts and there’s two USB-C charge points in the back of the centre console, but there's no directional air vents unless you opt for the dual-zone climate control that comes standard with the M135i. 

The boot has grown by 20-litres to a pretty impressive 380 litres VDA which includes a very useful cavity under the floor instead of a spare tyre. An inflation kit is there for those duties. With the back seat folded flat, boot space expands to 1200 litres VDA. 

My family found the X1 xDrive20i to be one of the most practical small SUVs we’ve lived with thanks to its spacious interior, clever cabin storage and plenty of convenient features.

I need to point out the door pockets - they’re the biggest I’ve ever seen. They’re more door buckets than pockets and super helpful over the week not just for bottles but for everything else that I needed to dump out of my own pockets and into them.

The floating centre armrest up front looks like an ironing board and has a tonne of storage underneath.

The wireless charging is handy but the holster is a bit un-user friendly in terms of access, but it held the phone tight and stopped it becoming a projectile when driving, which is what you want.

There are power outlets galore, too, proximity unlocking, and a gesture tailgate.

Legroom in the back is excellent and there’s so much headroom throughout. 

The X1’s 540-litre boot capacity is excellent for the class and meant we could fit our baby’s big pram and the seven-year old’s scooter and still have room for the grocery shopping.

In the space of driving this SUV and writing this review the list price of the X1 xDrive20i M Sport has risen from $68,900 to $73,400. 

That price hike was part of an increase across the model range and all grades now cost more, even the entry-level sDrive18i which is now 13K less than the xDrive20i M Sport.

But you’re paying for the more powerful, athletic and only all-wheel drive one in the X1 range. 

You’re also getting loads of standard features in the xDrive20i M Sport. 

There’s the 10.25-inch instrument display with three different styles for your speedo and other gauges, while flowing into that is the 10.7-inch media screen with sat nav, wireless Apple CarPlay and Android Auto, and digital radio. 

There are LED headlights, plus proximity unlocking, a head-up display, dual-zone climate control, a power tailgate, sports seats (the front ones are heated and power adjustable) and adaptive cruise control.

As the name suggests the xDrive20i M Sport is fitted with BMW M Sport goodies as standard. These include adaptive M Suspension, M leather steering wheel, M roof rails, M headliner and M interior trim. 

My test car also had $8900 worth of options fitted including the sunroof, Harman Kardon stereo, the ‘Vernasca Black’ leather seats and 20-inch M light alloy multi-spoke wheels.

Is it good value? Well, you do get a lot of nice things here but at a $13,000 premium over the entry grade, plus the $3500 price jump in the past few weeks, I’d say the value isn’t great.

If you’re trying to keep the cost down, the sDrive18i is the budget pick. 

Both cars use versions of the three and four cylinder petrol engines from before, with the popularity of automatics leaving the previous manual option consigned to history.  The 118i’s 1.5-litre turbo three cylinder now produces 103kW/220Nm, with max torque available all the way from 1480-4200rpm. The 118i now uses the seven-speed dual clutch automatic transmission, as seen on Mini models that use the same engine. 

The M135i’s 2.0-litre turbo has been tweaked to take the place of the six-cylinder M140i from the last model and now produces 225kW/450Nm, with max torque available all the way from 1750-4500rpm. Its auto remains a torque converter though, but now the transverse-mounted unit also shared with Mini models with the same engine and splitting drive to all four wheels via the xDrive system for the first time. The drive split is constantly variable, but the rear bias tops out at 50 per cent and the only limited slip diff is an electric unit on the front axle.

The X1 xDrive20i M Sport has a more powerful engine than the grades below it in the range - it’s a 2.0-litre, turbo-petrol, four-cylinder making 150kW and 300Nm.

A seven-speed dual-clutch automatic transmission does the shifting for you.   

This is also the only all-wheel drive X1 currently in the range.

Official combined fuel consumption is a decent 5.9L/100km with the 118i, but the M135i steps up to 7.5L/100km) 2.0 litre four in the m135i. Both engines require premium unleaded. 

Fuel tank sizes vary across the two models also, with the 118i measuring 42 litres and the M135i managing 50 litres, despite its need to package rear drive components somewhere under there also. 

This results in a decent theoretical range between fills of 711km for the 118i and 666km for the M135i. 

BMW says that after a combination of open and urban roads the X1 xDrive20i M Sport will use 7.4L/100km.

In my own testing my driving was mainly city and suburban, which uses quite a lot of fuel. We did dashes to birthday parties, the grocery shopping, school drop offs and all of it in busy traffic.  

I recorded 8.9L/100km, but that’s not overly thirsty considering I was carrying two car seats with children, and all the gear that goes with them. 

A small 45 litre tank means the xDrive 20i M Sport has a range of about 608km, which is on the shorter side.

For a brand with a marketing slogan of pure driving pleasure, this is the important part, particularly given the new 1 Series has lost its rear wheel drive USP. 

Why do some of us love rear wheel drive? It tends to be more fun when you're driving on the limit, and generally makes for nicer steering because you're only using the front wheels to turn corners.

So how does the new 1 Series drive? That depends on which version. 

The 118i is quite a nice package really. It rides a bit more gently than what I remember in the A-Class and generally feels more like a premium product. It also feels a step ahead of the 2 Series Active Tourer it shares its underpinnings with, which is a good thing.

The three-cylinder engine is quite smooth for a fundamentally unbalanced triple, and it makes enough power to get you out of trouble. 

Do you miss rear wheel drive? Not really, as you can only tell the difference when you're going real fast, which let's face it, is not somewhere 118i drivers are likely to go very often. 

The M135i is a vastly different beast, as you'd expect. Aside from being real quick, it's that much tighter everywhere, but still definitely on the more comfortable side than what we expect the future full house M version to be.

The continuously variable xDrive all-wheel drive system does a great job of putting its power down, but the rear bias maxes out at 50 per cent, which is probably spot on for chasing lap times, but means you miss out on the tailiness of the old one altogether. 

So it’s not as classically fun as the old M140i, but it’s easily faster, and that's what will probably matter most to most buyers. 

Only a week before testing the X1 xDrive20i M Sport I’d been reviewing a BMW 330e and going from the 3 Series to the SUV was like changing my seating position from being in a bathtub to sitting on a bar stool. 

Actually, the X1’s seat is far more comfortable than a stool and the refined quality is what you’d expect from BMW.

But compared to the low slung 330e the visibility and the upright driving angle of the X1 is very different.

It’s something you want in an SUV that puts practicality before performance.

As much as I liked the sporty sedan, as a dad I preferred being able to see better when parking in the X1, and this made life a lot easier.

Easy is a good word to describe what the X1 xDrive20i M Sport is like to drive - from that visibility to the light steering, comfortable ride and that great engine with all-wheel drive.

That 2.0-litre four-cylinder has more than enough grunt to run up the steep hills in my neighbourhood without struggling, the transmission is smooth and the all-wheel drive system adds a bit more reassurance in the wet weather.

All of this makes for an easy, enjoyable drive. 

The X1xDrive20i M Sport like all X1s scored the maximum five-star ANCAP rating in 2022.

A score of 88 per cent was given to child protection and the ANCAP report found that a 10-year old and six-year old in the second row had adequate to good protection in a front offset collision and a side impact. 

For child seats there are two ISOFIX points and three top tether anchor mounts across the second row.

As you would expect from a model that’s hasn’t even been around a year yet, the X1 xDrive20i M Sport has the very latest in advanced safety tech.

There’s AEB which is operational from 5.0km/h to 210km/h and also works at road junctions. There’s lane keeping assistance, blind-spot warning and rear cross-traffic alert. 

There are curtain airbags for front and rear passengers, a centre airbag for the driver and co-pilot along with frontal airbags plus side chest and side pelvis airbags.

BMW is yet to step up to the five year warranty offered by most mainstream brands and now Mercedes-Benz and Genesis, continuing with the three year/unlimited coverage matched by Audi. 

As always, BMW describes the service intervals as condition based, and the car will alert the driver when a service is due. This will occur at least every 12 months though, but individual intervals will vary based on how the car is driven. 

This can all be bundled into five year/80,000km service packs though, with the Basic pack costing $1465, but the Plus pack adds brake pad and disc replacement to regular fluids and consumables for $3790. Assuming 12 month intervals, these prices are about average for a premium branded product. 

The X1 xDrive20i M Sport is covered by BMW’s five-year/unlimited kilometre warranty.

A five-year/80,000km service plan through BMW will cost $2150. You’ll be looking to pay an average of $430 per service every 12 months.
