BMW Alpina B7 vs Mahindra Xuv 3Xo

What's the difference?

The BMW Alpina B7 is a special car destined (like all Alpinas) to be a collector's item, due to its rarity and exclusivity. I asked Alpina just how many current model B7s there are in Australia and the answer was "less than five", which is just as mysterious as most people find the car in general.

The B7 is fast – too fast to enjoy legally on Australian roads – but it is also supremely comfortable and well appointed. For Alpina fans lucky enough to be driven in on,e this would make for a truly rare and niche way to be chauffeured.

The fact this is Australia’s cheapest SUV is a massive feat for the Indian brand. It also has so much standard kit so this is even more surprising.

In many ways the XUV 3XO is better to drive than its rivals. The three-cylinder turbo engine has plenty of charm and moves this car along with ease, the car feels confident and composed out on the open road, and there aren’t any bings and bongs from intrusive safety systems.

However, things aren’t perfect. I wish the steering column offered reach adjustment, the steering feel wasn’t so inconsistent and the lane-keep assist wasn’t so hands-on.

If you can overlook these quibbles, this tiny Mahindra is an outstanding value buy if you’re considering a first new car.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

This is a good place to start because the B7 looks just like the 750Li it's based on, until you see the first tell-tale signs that it's not one.

There's the front wing with Alpina lettering and the boot-top spoiler, the graphics, which run the length of the car, and the 20-spoke wheels with Alpina badging.

This is late '70s, early '80s styling at its best (and possibly worst), but these special cars can pull off the irony-free look because this is how Alpina BMWs have rolled since 1975, when the E21 320-based Alpina A1/3 was launched.

BMW badges have been left on the bonnet and boot, but there's Alpina B7 BiTurbo lettering in place of the 7 Series identifier.

Most people walked by it in the street thinking it was just a big BMW, others scratched their heads wondering what I'd done to my big German limo and a handful almost dropped to their knees in praise and wonderment at spotting a rare beast like this in the wild.

These people all had their own Alpina stories – one was the third generation of an Alpina-owning family. You become a member a small and passionate club when you buy into this rarefied brand.

The standard B7's cabin is close to identical to the luxurious interior of the 750Li, save for Alpina-embossed stitching in the headrests of the soft, leather seats, the virtual instrument cluster and the Alpina plaque on the centre console denoting the build number.

The B7 is long, low and wide at just under 5.3m end to end, 1.5m tall and 1.9m across. A 3.2m wheelbase means cabin room is more than just spacious.

The B7 rolls off the Dingolfing production line in Germany and is then handed over to Alpina's facility in Buckle, where significant changes take place. Read on to find out how the B7 is different from a regular 750Li.

From outside it’s surprising just how small this SUV is. At just under four metres long, the XUV 3XO is shorter than a Mazda2, for example.

The reason for this is because in India there are tax breaks for vehicles under four metres long. The Ford EcoSport, sans the tailgate-mounted spare wheel, was another SUV that met this requirement.

As a result of being so short, this has made the rear overhang virtually non-existent. It’s a strange look, especially because the bonnet is so much longer.

Even though the XUV 3XO is based on the KGM Tivoli (formerly SsangYong Tivoli), which was briefly sold in Australia, you’d be hard-pressed to find visual similarities. The former looks more modern from the outside and has more visual interest with the chunky wheel-arch cladding and diamond motifs.

At the front it’s hard to not see the face of a sad panda. The LED headlights are big and plunge down the front fascia, giving it a droopy and sleepy appearance. It’s not helped by the thick black bar connecting them.

Around the side the diamond-cut alloy wheels are a nice touch, along with the contrast black-painted roof on this AX7L tester.

The rear end is a little on the flat side, though the badging is tasteful. I’m not a fan of the full-width LED light bar, however, as it’s an overdone design cue now.

Inside I appreciate the mix of both old-school and new-school. There are dual 10.25-inch screens ahead of the driver for the digital instrument cluster and touchscreen multimedia system, as well as plenty of physical buttons and knobs for shortcuts and the climate controls.

For such an affordable car I’m surprised how many soft-touch finishes there are in this car. In the AX7L you get an extended use of synthetic leather on the door cards and dashboard, which helps make for a pseudo-premium look and feel.

However, one of my biggest gripes with the XUV 3XO interior is the amount of glossy piano black. It’s on the dashboard, centre console, door cards and even the steering wheel.

This may look cool and slick when you pick the car up from the dealer, but it shows up dust quickly and then gets scratched when you try to wipe it clean. Our tester had fewer than 1000km on the odometer and the centre console was already scratched to the wazoo.

The B7 is a five-seater limousine although with the fold-down rear centre armrest which houses the media control panel the back is really set up to carry two.

That 3.2m wheelbase means cabin space is enormous. At 191cm tall I can sit behind my driving position with about 30cm between my knees and the seatback. Those rear doors open wide and the entrance is huge, making entry and exit almost as easy as just walking through a doorway. The air suspension also rises and lowers the B7's ride height for better access.

Storage is excellent, with two cupholders and door pockets for rear passengers, along with the area inside the centre armrest.

Up front, the driver and co-pilot have a deep centre console storage bin with split-opening lid, two cupholders and door pockets.

Luggage space is good, with a 515-litre boot.

Given this SUV is tiny, I’m blown away at how much interior space it has.

Up front both the seats are manually adjustable, which is to be expected at this price point. Despite this, they’re still comfortable and offer an elevated driving position which is something SUV buyers seek.

In front of the driver is a leather-wrapped steering wheel which feels nice in the hand. While it offers tilt adjustment, it disappointingly doesn’t have reach adjustment. This is frustrating if you’ve got long legs and short arms, like myself.

The 10.25-inch digital instrument cluster has an overall dark and minimal look, but you can cycle through a range of informative views. There’s even one that allows you to display a full-width map.

Moving across, the 10.25-inch touchscreen multimedia system appears to be snappy enough. I’ve experienced fewer glitches in this car than in previous Mahindras I’ve driven.

I like the physical shortcut buttons underneath the touchscreen because it allows you to jump around to key sub-menus a lot easier.

As standard there’s both wired and wireless Apple CarPlay and Android Auto connectivity. With my iPhone 15 Pro Max the connection was flawless and only dropped out during known interference points.

This AX7L spec comes with a seven-speaker Harman Kardon sound system which gets this tiny car booming. The subwoofer in the boot is so powerful it almost feels like overkill.

In terms of storage up front there are two cupholders, big door pockets with two bottle holders, a centre armrest and a cooled glovebox. There’s also a USB-A port, 65W USB-C port and a wireless charger.

Moving to the second row there’s a decent amount of space for adults to sit behind adults. You could easily fit two adults along the rear bench, though pushing it to three would get a little too squishy.

Second-row amenities include rear air vents, a USB-C port with a phone slot, as well as a fold-down armrest with cupholders.

At the back there’s a manual tailgate, which is to be expected at this price point, but finding the trigger to open it is a little tricky. It’s a small button that’s hidden away.

Once the tailgate is open, the amount of boot space on offer is generous. Mahindra claims there’s 364 litres with the rear seats upright.

While the loading lip is high, the boot area is deep and wide. Unfortunately there’s no cargo cover available as standard, which means you’ll need to be careful what you boot back there.

Under the boot floor there’s a space-saver spare wheel, which is fantastic peace of mind if you travel long distances away from tyre repair shops.

The Mahindra XUV 3XO is currently Australia’s cheapest SUV.

There’s a caveat, however, because this is thanks to an introductory pricing offer that ends on August 31.

Currently though, the XUV 3XO line-up starts at $23,490 drive-away for the AX5L and extends to $26,490 drive-away for the AX7L, as tested here.

After August 31 the drive-away asking price of both of these XUV 3XO variants is set to go up by $500. This will see it share the title of Australia’s cheapest SUV with the Chery Tiggo 4.

Despite the affordable asking price, Mahindra has packed a lot of standard kit. This includes 16-inch diamond-cut alloy wheels, 10.25-inch digital instrument cluster, 10.25-inch touchscreen multimedia system, wireless Apple CarPlay and Android Auto, six-speaker sound system, dual-zone climate control, electric park brake with auto-hold, keyless entry and push-button start, leather steering wheel and gear selector and black cloth upholstery.

For an extra $3000 in the AX7L you get a black-painted contrast roof, 17-inch diamond-cut alloy wheels, LED front fog lights, panoramic glass sunroof, seven-speaker Harman Kardon sound system, 65W USB-C charger, cooled glovebox, black synthetic leather upholstery, and synthetic leather on dashboard and door trims.

Alpina takes the 4.4-litre twin turbo V8 from the BMW 750Li and rebuilds the engine by hand. Alpina fits its own turbochargers, air-intake set -up, high-capacity cooling system and Akrapovic quad exhaust. Output is 447kW and 800Nm – an increase of a whopping 117kW and 150Nm over the 750Li's grunt.

It's interesting to note that the V12-powered 760Li has a smidge more power, at 448kW, and the same torque output as the B7.

How fast is the B7? Supercar fast – the B7 has a top speed of 330km/h, which will see it outrun a McLaren 570 and almost keep up with a Ferrari F12. That's quite incredible for a 2.3-tonne limousine with three TVs on board. A 0-100km/h time of 4.2 seconds is also hugely impressive.

In comparison, a 750Li has a 0-100km/h time of a not-too-shabby 4.7 seconds, but the car is electronically limited to 250km/h.

An eight-speed automatic transmission shifts gears smoothly, although a little slowly in Normal mode, while Sport and Sport+ add urgency and harder shifts.

Finally, the B7 is all-wheel drive, and those rear wheels are designed to steer slightly for better cornering performance.

All variants are powered by a 1.2-litre turbocharged three-cylinder petrol engine that produces 82kW of power and 200Nm of torque.

This is mated to an Aisin-sourced six-speed torque-converter automatic transmission with drive sent to the front wheels only.

The B7 is probably not the car to own if you're concerned about either fuel prices or emissions, but then the twin-turbo V8 may not be as thirsty as you'd think, with Alpina stating that, after a combination of urban and open-road driving, you should only use 9.6L/100km.

My time in the B7 saw me double that usage but this could have had something to do with me turning off the stop-start system and driving in Sport mode constantly.

Mahindra claims the XUV 3XO has a combined urban/extra-urban fuel consumption of 6.5L/100km.

During my testing, however, I achieved a real-world fuel consumption figure closer to 6.2L/100km, which is better than the claim.

All XUV 3XOs have a 42L fuel tank that Mahindra claims can take 91 RON regular unleaded petrol, but 95 RON premium unleaded petrol is recommended.

With my as-tested fuel consumption this means the theoretical driving range from a full tank of petrol is around 675km.

Who on Earth thinks a BMW 750Li isn't fast enough or comfortable enough, even with all its horsepower, luxurious cabin and technology? Alpina, that's who.

Redevelopment of the 4.4-litre V8 with new turbochargers, a high-capacity cooling system, different air suspension set-up and an exhaust system made by Akrapovic have made this already exceptional car better. Better to drive and better to be driven in.

The ride, even on those 21-inch wheels and low-profile Michelin Pilot Super Sport tyres (255/35 ZR21 on the front and 295/30 ZR 21 on the rear) is incredibly comfortable. I drove it and also had a chance to recline in the back and be chauffeured (by our photographer) and the ride was so composed and refined it was hard to believe I was travelling along some truly awful urban roads with their cracked and pot-holed surfaces.

And it's quiet, too. Which will suit those in the back being transported swiftly from the airport to their next meeting, but if you're after a loud and angry exhaust note then you won't find it in the B7. Sure, from the outside at full throttle the B7 has a menacing growl, but this isn't a BMW M car that will bark and snarl. 
See, while BMW's M division makes brutal, loud, high-performance versions of their regular cars, Alpina makes comfortable, stealthy, high-performance ones.

All-wheel drive provides fantastic traction and ensures that grunt doesn't just tear the tyres off those rims when you sneeze on the throttle.

And while the air-suspension is soft and comfortable, adaptive dampers adjust for when the road goes twisty, providing impressive handling for a heavy and long car.

Really, though, the B7 is built for long, endless stretches of roads, and the acceleration beyond 100km/h is almost as startling as that from 0-100km/h, as it wants to push straight past 200km/h towards that 330km/h top speed.

Which, unless you know a good lawyer or happen to be one, will send you straight to jail. Yes, the B7 is probably too much car for Australian roads. Only on a German autobahn would a B7 be fully at home.

I felt like I was given a Melbourne Cup-winning racehorse for a week but could only ride it in my suburban backyard.

Behind the wheel, the Mahindra XUV 3XO feels refreshingly old-school.

The 1.2-litre turbocharged petrol engine does seem like it would be underpowered, but in practice it’s completely adequate. Peak torque comes on tap from 1500rpm so it doesn’t have to work too hard at all.

It’s fun hearing the noise the three-banger makes when under the boil. You don’t hear it much though because the revs are typically kept down low to minimise fuel consumption.

The key reason why this car feels old-school is the six-speed torque-converter automatic transmission. It’s nice to not drive an affordable everyday car that doesn’t have a continuously variable transmission (CVT) or dual-clutch automatic transmission as these can suck the life out of a car or be jerky.

The gear shifts in the Mahindra are sometimes docile, but are smooth and measured. It just operates like a regular car that doesn’t require you to rewire your brain to drive.

There are three drive modes to choose from. They’re hilariously called ‘Zip’, ‘Zap’ and ‘Zoom’. These correspond to Eco, Normal and Sport, respectively.

While I did eventually get used to driving in the ‘Zap’ mode, it felt a little snoozy at points, taking a beat or two to get the car accelerating with traffic. You can sidestep this with ‘Zoom’ which feels much more lively. If you activate cruise control or restart the car, though, it defaults back to ‘Zap’.

The XUV 3XO makes the most sense in the city where you’re able to use its tiny exterior dimensions to navigate tight urban carparks and narrow laneways with ease.

It almost became a challenge for myself to find the smallest parking spot I could slot this car into. As standard on this AX7L there are front and rear parking sensors, as well as a surround-view camera system.

Where this car is let down, however, is the steering feel. It’s incredibly light at low speeds and then as the speed builds it gets very heavy. So much so it feels like I’m getting an arm workout.

Unlike some of its rivals, there is still a semblance of feel through the steering wheel, but this drastic change from light to heavy steering weight is too stark. Somewhere in the middle would be nice please.

Something Mahindra is very good at is developing a comfortable suspension tune and this car is no different. It can tackle pimply urban road imperfections and speed bumps with no problems whatsoever.

Out on the open road this car surprised me. It feels like a much larger car than it actually is and doesn’t get blown around in the lane like small cars can.

The three-cylinder turbo-petrol engine remains confident at higher speeds, though if you frequently travel up hills the fuel consumption will skyrocket. There’s also a bit of road noise, which is to be expected when a car is this small.

For the most part the suspension does a fantastic job at rounding out road imperfections, but bigger bumps or potholes can unsettle the car. It’s not helped by the larger 17-inch alloy wheels.

Out in the twisties this tiny SUV is fairly agile. It’s not the sportiest thing out there by a vast degree, but it remains planted and solid even when pushed into harder corners.

Lastly, another point that makes this car feel old-school is the lack of obtrusive bings and bongs from the safety systems.

Sure the parking sensors can be a little over-the-top and the traffic sign recognition takes over the entire digital instrument cluster when it picks up a new speed limit, but having no driver attention monitor and intelligent speed limit assist is refreshing.

It’s not all perfect however as the lane-keep assist is too hands on for my liking. It activates from 60km/h and is quite overt in how it directs the car through bends.

The Mahindra XUV 3XO hasn’t been crash-tested by ANCAP just yet.

It was, however, tested by India’s less stringent Bharat NCAP testing authority in 2024 and received a five-star rating.

Standard safety equipment includes autonomous emergency braking (AEB), lane departure warning, lane-keep assist, lane centring, adaptive cruise control, traffic sign recognition, rear parking sensors and a reversing camera.

Stepping up to the AX7L gets you a surround-view camera, blind-spot view camera, and front parking sensors.

Notably absent from the entire range is rear cross-traffic alert, as well as a traditional blind-spot monitor that alerts you when a car is in your blind-spot.

There are two ISOFIX points on the two outboard rear seats, as well as three top-tether child seat anchorages across the rear bench.

The B7 is covered by BMW's three-year, unlimited-kilometre warranty. Servicing is recommended every 12 months or 15,000km. The B7 is covered by BMW special vehicles servicing plan, which means services are cost-free for the first three years of the car's life.

Like other current Mahindra models, the XUV 3XO is covered by a seven-year, 150,000km warranty with seven years of roadside assistance.

Logbook servicing is required every 12 months or 15,000km, whichever comes first, though the first service is required after 12 months or 10,000km.

The first seven services are capped-price and total $1994. This averages out to $284.85 per service.
