What's the difference?
The BMW Alpina B5 Bi-Turbo is not actually a BMW. Not according to the German Federal Motor Transport Authority, at least.
Nope, the modifications applied by tuning house Alpina to the 5 Series are deemed so significant that if you open the bonnet and look inside the engine bay, you'll see that the BMW VIN has been struck through twice and an Alpina vehicle number stamped underneath it.
The B5 is not the first model to be recognised in this way, either; the German government has recognised Alpina as a seperate car manufacturer since 1983.
The B5 has other ‘B' siblings, too. There's the B3 S Bi-Turbo, which is based on the BMW 3 Series, the B4 S Bi-Turbo (the BMW 4 Series) and the B7 Bi-Turbo (I don't need to tell you what this is based on, right?) which I've reviewed, too.
So just what has Alpina done to this unsuspecting BMW 5 Series? Is it really worth the extra money? How does the B5 compare to an M5? Could it actually be superior? And did they really take the speed limiter off to let it warp-speed to beyond 300km/h?
The B10 isn’t Leapmotor’s first car in Australia - the C10 has been here for more than a year now - but for many it might bring about the first time they hear about the Chinese brand.
The 2026 Leapmotor B10 lands in Australia promising to be the most European of its Chinese compatriots, with the brand’s connection to Stellantis giving it access to other brands under the company umbrella like Alfa Romeo, Maserati and Peugeot.
At its local launch, we get behind the wheel in scorching south-east Queensland to find out if that holds true for this electric small SUV, and to see if the B10 can bring with it a better first impression than the already-arrived mid-size C10.
The Alpina B5 is a special car – more special than most people will ever give you credit for if you own one. Those that do know what an Alpina is will let you know; people will cross dangerously busy streets to talk to you about your car. Insanely fast, almost incomprehensibly comfortable and effortlessly powerful to drive.
I’ll be a shame if the B10 doesn’t sell well, because it doesn’t suffer from many of the downfalls of its compatriots and its price is extremely competitive for what you get.
As a comfortable smallish SUV, it meets par, and it’s on the better side of tech when it comes to cars from China, and it doesn’t have any major on-road red flags.
You really wouldn’t be disappointed with this having paid $40K, just skip the base model and go for the Design.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.
Interesting is the right word for it, because while it might be questionable that Alpina's changes to the exterior are aesthetic pleasing, they are definitely intriguing to those who aren't familiar with the brand.
First, there are those 20-spoke wheels. Alpinas have worn this style of wheel forever and they've become the most famous outward sign that this is not just another BMW. So don't under any circumstances take them off and replace them with anything else. You'd be run out of town by the Alpina mafia.
Yes, they're more painful to clean than a cheese grater (trust me, I know. And if you look closely at these images you can see the dirty bits I've missed), but if you really don't like them then perhaps it's a sign this car isn't for you.
Then there's the boot-lid spoiler. It's square and 1980s'-looking, it also appears a bit like it's been bought online and installed by a teenager, but again, this is another Alpina tradition and it suits the car's character perfectly.
All right, those pinstripes; they're known as the Deco-Set and are a hat-tip to the Alpina racecars of the 1970s and '80s. Again, don't take these off, your Alpina will drop through the centre of the Earth in value. These are also part-and-parcel of owning one of these cars. I'm not a massive fan of them.
But I'm all about that front spoiler, with the floating Alpina lettering that you can option in silver, high-gloss black or gold.
Inside, there are fewer Alpina additions, but they're nonetheless unmissable. There's the Alpina-badged steering wheel, and a new virtual instrument cluster, embossed headrests and illuminated door sills.
There's also the little numbered plaque on the centre console which proves its authenticity, ours was number 49. Out of how many? I don't know. But I do know Alpina produces only about 1700 cars globally a year. Rolls Royce does about 4000. So, you can rest assured your B5 is exclusive.
At almost 5m long, 1.9m wide and 1.5m tall, the B5 is a large saloon, but having recently reviewed the Alpina B7 it feels small in comparison. How does it drive? We're getting there.
Right after we praise the B10 for its value, we need to talk about its looks. A slight drop in tone as the second Leapmotor to land in Australia looks an awful lot like the first, and it’s relatively bland.
It’s not ugly, but it’s not particularly inspiring and there’s not much character to this little electric SUV.
It’s got a very upright silhouette at the front with a slightly sloping roofline at the rear, so the overall shape is appealing, but the lack of distinct features makes the B10 an anonymous commuter for now, especially with its similarities to the C10.
You can tell them apart by the C10’s slightly larger size if they’re near each other, or the B10’s more in-line headlight bar, where the C10’s have a ‘droop’ at the sides.
The large section of black at the lower half of the front is also unappealing, though darker colours like the optional 'Starry Night Blue' or 'Dawn Purple' (both $990) blend into it better than standard 'Light White'.
To its credit, at least the B10 doesn’t fall victim to the design crutch of adding trim and plastic for no reason.
In terms of the specifics, the B10 is 4515mm long, 1885mm wide and 1665mm tall with a 2735mm wheelbase, making it quite the large small SUV.
Inside, the cabin looks and feels roomy thanks to the test car’s light interior, decent windows and the light from the sunroof, as well as the fact the EV powertrains are compact and generally don’t interfere with cabin space.
Materials aren’t all scratchy hard plastic, though it is dotted around, and the general look of the B10 inside feels more premium than its price would have you thinking, despite the simplicity of the layout and design.
Practicality is not really a BMW strong point no matter which model you pick. See, BMW mostly makes the car equivalent of uber-stylish and skin-tight active wear which looks good and performs brilliantly, but sometimes you just want pockets and a bit of room for your… um… bits and pieces.
So while there are two cup holders up front and two in the back, the bottle holders in the doors aren't huge, the centre console bin is on the small side, there's a hidy-hole in front of the shifter, the glove box is just a box for little more than gloves and there's no other great cabin storage options.
Legroom in the rear is good but not great, too - I'm 191cm tall and have about 30mm between my knees and the seat back in my driving position. Middle-seat passengers will also have to straddle the drive shaft hump in the floor. Headroom is restricted in the back, too (you could blame the sunroof) with my hair just skimming the headlining (I do have big hair).
Under that power tailgate, the B5's boot capacity is 530 litres which is 15L more than its big sister, the B7. There are two plastic storage areas either side of the luggage space for wet things. While there is one USB outlet in the front there aren't any in the rear.
Getting into the B10 requires a minor annoyance - unlocking and locking the car requires a keycard to be tapped on the drivers’ side mirror like you're scanning to access your floor in a hotel elevator.
There’s an app that adds a fair bit of functionality, but having to whip your phone out ahead of jumping in the car is also irritating.
Once you’re in, though, the space inside the B10 is well laid-out, even if much of its functionality is crammed into the big central touchscreen - it’s always ‘points off’ for a lack of physical buttons in this section of a review.
Once you’re used to it and have sorted out your personal settings on the multimedia software, it becomes more natural and less distracting, though Apple CarPlay and Android Auto would occasionally lag in the car on test.
The good news is they now exist for the brand in the B10, with the Leapmotor C10 still lacking the vital in-car mirroring tech.
The ergonomics and interior space work well, generally, with comfortable pews and good vision, plus decent spaces to keep things out of the way. The phone charger being in a very visible and accessible position might tempt some naughty screen-keen drivers, and being in the sun without a vent for cooling while charging means your phone will get proper hot.
The second row is extremely spacious, belying the fact this car is classified as a small SUV. Oodles of legroom and enough headroom for a tall adult means the B10 outguns rivals in terms of good options for parents (note the B10’s extremely strong 95 per cent child safety score from ANCAP, too) or anyone who needs to cart humans around regularly.
Behind the second row is a 490L boot, which becomes 1475L when the second row is folded down.
There’s space under the floor for cables and messy bits, but unfortunately no spare wheel, just a tyre repair kit, so more points off for that.
The BMW Alpina B5 lists for $210,000, making it only $10K more the BMW M5 which comes with almost identical features apart from the Alpina engineering to the engine and chassis.
Arriving standard is leather upholstery, four-zone climate control, nav, the Alpina embossed-headrests, a 10.25-inch display, digital radio, Alpina door sills, sunroof, proximity key, power front seats, 12-speaker Harman Kardon stereo, head-up display, Alpina virtual instrument cluster, heated front and rear seats, and the 20-inch Alpina wheels.
The test car I drove had been optioned with a limited-slip differential ($5923), steering-wheel heating ($449); soft-close function for doors ($1150); sunblinds ($1059); TV function ($2065) ambient air package ($575), and front-seat ventilation ($1454).
Talking about the price may well be us highlighting the Leapmotor B10’s strongest point right up top, because you can get into one for less than $40K, drive-away, before the end of March 2026.
While regular pricing for the B10 starts from $37,888, before on-road costs, for the base Style and $40,888 for the kitted-out Design LR, Leapmotor has a limited-time deal starting from $38,990, drive-away, for the B10 Style and $41,990 for the Design LR. LR for Long Range, by the way.
That runs until the end of March, 2026, but even its standard pricing is impressive for what you get.
The entry-grade B10 Style comes with plenty of kit, including an 8.8-inch LCD driver display and large 14.6-inch central multimedia touchscreen, a wireless phone charger, auto climate control, a panoramic sunroof with retractable shade, heated mirrors, auto LED headlights, a set of 18-inch wheels, surround-view parking cameras with dashcam recorder capability, over-the-air (OTA) updates and Level 2 advanced driver assistance (ADAS).
That’s a list of inclusions that can, on paper, rival much more expensive models.
The Design LR, for not much more money, adds heated and ventilated synthetic leather seats with electric adjustment (six-way for the driver, four-way for the passenger), a heated steering wheel, a 12-speaker sound system, ambient lighting, a power tailgate, tinted privacy glass, LED tail-lights and auto folding mirrors.
You’d hate to be in the product planning team of a legacy manufacturer trying to put together a competitive spec for a small electric SUV to sell in Australia against that.
Even other small electric SUVs from China come with much smaller batteries or fewer features around the $40K mark, like the MG S5 EV Essence RWD with its 49kWh battery ($42,990 D/A) or the base Geely EX5 Complete FWD ($40,990 BOC) and the higher Inspire variant is $4000 more.
The Alpina B5 uses the same 4.4-litre V8 engine found in the BMW M5 (and also the B7). But, and it's a big but, the M5 makes 441kW and 750Nm, while the B5 outdoes it with 447kW and 800Nm. Admittedly, the B5's torque arrives at the 3000rpm mark, while the M5's is all there from 1800rpm.
How does the B5 beat it? Alpina installed its specially developed twin turbochargers and intercoolers, a high-performance cooling system, a reconfigured air intake set up and a different exhaust system.
The B5, though, is a tenth of a second slower to 100km/h compared to the M5 with a time of 3.5 seconds, but it will blast on to a top speed of 330km/h while the M5 is limited to 250km/h in regular form and 305km/h with the optional M Driver's package.
Both uses the same ZF eight-speed automatic transmission with identical gear ratios, and both are all-wheel drive.
There’s only one powertrain option for the Leapmotor B10, a single, rear-mounted electric motor that produces 160kW and 240Nm, which makes the electric SUV good for a claimed 0-100km/h time of 8.0 seconds in both variants.
Top speed is a claimed 170km/h, also regardless of the variant.
The Alpina B5 needs petrol. By that, I mean it needs quite a lot of it if you want to enjoy it properly. What type of mileage does it get? Officially, it should use 11.1L/100km after a combination of urban and open roads, where as the M5 is set to 10.5L/100km.
That makes sense, the B5 produces more power and torque, and it's 85kg heavier than the M5 at 2015kg.
Our test car's trip computer was reporting 13.2L/100km after flying low over country roads and slow city piloting. The more time spent in the urban warfare that is the daily peak hour commute, the more that figure crept and hovered around the 15L/100km mark.
Leapmotor claims the B10 will, from its LFP battery of either 56.2kWh for the Style or 67.1kWh for the Design LR, draw 17.2kWh/100km or 17.3kWh/100km, respectively under WLTP testing.
The result is the Style offering up a 361km WLTP-tested driving range, and the Design LR a more useful 434km.
While we were unable to properly confirm this claim on the launch, the trip computer after a mix of highway driving and more spirited back-road testing displayed a figure of 13.5kWh/100km, while the previous 1447km of driving had reportedly measured in at 14.7kWh.
Charging from 30 to 80 per cent takes approximately 20 minutes regardless of spec and battery size. The smaller battery can be charged via DC fast-charging at a maximum 140kW, and the larger at 168kW. Both max out at 11kW under AC charging.
Ok, stay with me here. For this next bit you'll need a fresh egg, a lounge chair, and it might be a good idea to have some plastic bags and carpet cleaner on hand.
First, in front of the lounge chair flatten out the plastic bag and place the egg on it. Next, sit down on the chair and very carefully rest the ball of your foot on the egg with as little pressure as humanly possible.
This is exactly how little force you need to apply to the go-pedal of the B5 to accelerate from a standstill to 60km/h in about five seconds.
If anything sums up the driving experience of the B5, it's that sense of effortlessness.
Stomp on that accelerator, and you'll be shot to 100km/h in 3.5 seconds, without a hint of broken traction thanks to the all-wheel-drive system.
The ride should have been terrible on 20-inch wheels shod in low-profile rubber (Pirelli P Zero 255/35 front, and 295/30 rear), but the Alpina-tuned air suspension is close to miraculous in the way it cushioned and censored the potholes out of Sydney's worst roads. Yes, it can be a touch floaty, particularly in the Comfort Plus setting, but this is benchmark-setting stuff for a comfortable ride.
Don't expect this beast to roar. Unlike the M5, the B5 gets its work done without deafening everybody around it. Sure, the B5's V8 sounds amazing when you push it, but it's not brash, not loud and not lairy. Buy an M5 or Mercedes-AMG E63s if you want to be heard half a block before you get home, but you won't get that with the B5 and its exhaust system.
The B5 also handles well, but I have to say the engagement factor is low. I piloted it effortlessly through the twists and turns of my country test circuit and roads which normally have me grinning like a maniac behind the wheel had me feeling a bit disconnected in the B5. That air suspension, the numb steering and pedal actions make it difficult to ‘feel' the road.
It's highways where the B5 is a king, but even at 110km/h there's the sense that this car is still fast asleep and won't get out of bed for anything less than 150km/h - making it perfect for Germany's autobahns, but maybe not for here in Australia.
The Leapmotor B10 was developed with testing at Stellantis’ European proving ground in Italy. This is because despite Leapmotor being its own brand within China, its international operations are a joint-venture between itself and Stellantis.
There are some on-paper shreds of evidence for this, a rear-wheel drive layout and a claimed 50/50 weight distribution help, but get the B10 on the road and it’s clear this isn’t a car that’s relying entirely on price, a long list of features and some showroom shine to sell.
After the initial familiarisation that comes with many new electric cars, particularly from China, the Leapmotor B10 becomes easy to settle into a rhythm with, especially if you turn off some of its more intrusive ADAS features like lane-keep, driver monitoring and speed limit warning. The latter can sometimes get a limit wrong, and though the B10’s chimes aren’t audibly overbearing, they are persistent.
While the B10 doesn’t excel in any areas on the road, it doesn’t fall down significantly in any either.
Its suspension soaks up bumps relatively well, and despite some vibrations on rougher roads the B10 is pretty comfortable. The tyres it rides on as standard, however, are rather noisy, so if there’s an opportunity to swap out the Linglong defaults to something better, we’d advise it.
The tyres also squeal rather quickly when cornering, not necessarily because the B10 is about to let go, but just because the weight of the car appears to be pushing on the front outside tyre in cornering.
The B10 holds up better than\ a family car really needs to in dynamic driving, but we wouldn’t be doing mountain runs or track days in one.
There’s a little body roll in corners, but not nearly as much as has been in other models riding on the apparently soft suspension preferred in China.
The steering, braking and acceleration all have a mild vagueness to them, but once you’re honed in they’re all predictable. The steering can be adjusted for weight, and its lightest setting is too light, while the acceleration feels lethargic in its lowest setting and too aggressive in its highest.
There’s not a lot of regenerative braking strength, but it’s enough to help regulate speed once you’re used to how mildly it comes in - again, depending on your preferences and settings.
The good news here is that the B10 is easy to drive, and only very serious road bumps on fast corners unsettled it on test - the kind you’d expect to upset any car.
The Alpina B5 is based on the BMW 5 Series which had a five-star ANCAP rating awarded to it in 2017.
Along with the comprehensive suite of airbags, traction and stability control, there's an impressive array of advanced safety equipment. Coming standard is AEB (front and rear), evasive steering, front and rear cross-traffic warning, blind-spot alert and lane-keep assist. The Alpina B5 also comes with BMW's emergency call function.
For child seats you'll find two ISOFIX mounts and three top tether points across the rear row.
safety
If you're unfortunate enough to get a flat tyre, there's a puncture repair kit in the boot which works provided the hole isn't giant, as I've experience in the past with these systems.
The Leapmotor B10 was bestowed a five-star ANCAP rating in early February 2026 under the body’s most recent criteria.
There are seven airbags, including an important centre airbag, plus the B10 boasts 17 ADAS systems with 12 cameras and sensors helping monitor the road, surroundings and the driver.
As mentioned, those systems can be a little intrusive sometimes, but less than other new models from brands new to Australia.
The B10’s list of safety features includes multi-collision braking, collision sensors, an emergency data recorder, the aforementioned dashcam-style surround-view recording system, belt pretensioners, plus all the elements of the ADAS suite Leapmotor calls 'Leap Pilot'.
This includes adaptive cruise and lane centring, lane departure warning and emergency intervention, collision avoidance and warnings, blind-spot detection, rear cross-traffic alert and brake, speed assist, and driver monitoring and distracted driver warnings.
For baby capsules and child seats there are three top tethers across the second row with ISOFIX anchors on the two outer positions.
The Alpina B5 is covered by BMW's three-year/unlimited kilometre warranty. Servicing is recommended every 12 months or 15,000km.
The B10’s post-purchase prospects are generally solid, though Leapmotor’s six-year, 160,000km warranty is an area where it falls short of rivals which are offering longer, unlimited kilometre warranties.
The battery is covered for eight years or 180,000km, whichever comes first, which is pretty par for an EV.
Servicing is capped-price for the first eight years, with each service costing $370 on average. The eight-year span makes it pretty appealing, per 12-month interval or every 20,000km.
There are currently 20 dealers across the country, though more are coming, while Leapmotor also offers eight years of roadside service.
