BMW M235i vs BMW Alpina B7

What's the difference?

The badge might say one thing, but the 2 Series Gran Coupe sticks to the time-honoured template of being a compact yet comparatively practical three-box, four-door sedan, complete with a big boot.

More importantly, it drives and behaves like a BMW – which means sufficient-to-strident performance depending on grade, athletic dynamics and pleasing refinement on one hand, as well as a stiff price and a hard ride on the other.

A true BMW in name and nature, then..

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.

BMW is calling the F74 a new-generation 2 Series Gran Coupe, and there have been obvious and even profound changes throughout and underneath, including to some of the sheetmetal.

But this is not an all-new car by any stretch, with the glasshouse, doors and roof amongst many other body items carrying over from the F44.

That now remarkably Kia Cerato-esque nose ushers in new LED lighting motifs and an updated kidney grille, but whether they sit easily with the rest of the car is debatable. Redesigned tail-lights, different colours and new alloys make up the majority of the exterior changes.

Betraying the latest 2 Series Gran Coupe’s newness claims are near-identical dimensions, with that redesigned front end and bumpers contributing to a 20mm increase in the F74’s 4546mm length, while revised suspension and damper settings help account for the 25mm boost in height (to 1445mm). The BMW’s 1800mm width and 2670mm wheelbase remain the same.

There’s a higher level of newness to be found inside.

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.

During the media presentation at its launch, BMW described the 2 Series Gran Coupe as being almost as large as a 1990s E46 3 Series, and it is in all major dimensions except wheelbase.

Plus, being a front-drive-biased/transverse engine proposition instead of rear-wheel drive should make it roomier than the F74’s iconic ancestor.

The sense getting in is that this is certainly not too low or cramped as per a more-traditional coupe, with plenty of space for legs and shoulders, while even the optional sunroof fitted to our 218 left us with headroom to spare.

The redesigned dash is a visual and operational treat, with crisp, clear instruments, a logically presented and intuitive centre display screen offering fast and easy operation, excellent ventilation and ample storage. Full marks here.

Better still, attaining the perfect driving position is possible for most people, on brilliantly supportive front seats. This is the stuff BMW does right.

Improvement suggestions for the next update? Some people may complain about the somewhat less-than-premium feel of some of the lower-lying plastic trim; not everybody will love the swatches of colour stitching (we love it); why does the steering wheel have to be so wide-of-rim? Side and rear vision is restricted by fat pillars, rising shoulder lines and a shallow rear window; and there is quite a bit of road noise that enters the cabin at speed.

Still, even the back seat is sufficiently spacious for most users, with the sole exception of taller folk having to negotiate a sloping rear roofline. If you’re below 180cm, this should be fine. Most amenities minus overhead grab handles are also fitted.

Further back, the boot is surprisingly accommodating, with 430 litres of cargo capacity that’s enhanced by a 40:20:40 split-fold backrest, and the aperture should be big enough for bulkier loads, but the lack of a spare wheel will be bad news for many buyers. The supplied tyre-repair kit is just not good enough.

But, you know what is good enough? The engines BMW builds, that’s what.

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.

The B7 lists for $389,955, while a 750li is about $319,000. At this level, $70K seems like a downright reasonable premium to pay for a faster, more powerful, better handling and comfier version of the 750Li.

In this case you're paying more but getting more, although standard features are close to identical. There's adaptive LED headlights, head-up display, night vision with pedestrian detection, a 10.25-inch touch screen up front and two screens in the second row for TV and other media functions.

There's a reversing camera, sat nav, harman/kardon surround stereo and Apple CarPlay. There's leather upholstery, seat massagers in the front and rear, four-zone climate control, heated and ventilated front and rear seats, front and rear parking sensors, auto tailgate, sunblinds for the rear and rear-side windows and proximity key.

The safety features are listed in the section below, and that list is also impressive.

Rivals to the B7 include the Mercedes-AMG S63, which lists for $375,000, the $331,700 Audi S8 and even the Bentley Flying Spur, which almost matches its price at $389,500.

Three F74 powertrain choices are available for Australia in 2025. And none even remotely reflect what their respective badges imply on the boot.

The 218, for instance, is not powered by a 1.8-litre engine, but BMW’s long-lived B38 1.5-litre three-cylinder turbo petrol unit. Making 115kW of power at 6500rpm and 230Nm of torque between 1500rpm and 4600rpm, drive is channelled to the front wheels via a seven-speed dual-clutch transmission (7DCT).

With a kerb weight of 1420kg, the 218 has a power-to-weight ratio of 81kW per tonne, helping it achieve the 0-100km/h sprint time of 8.6 seconds, on the way to a 230km/h top speed.

Not enough? The 220 features the ubiquitous B48 2.0-litre (not a 2.2-litre) four-cylinder turbo petrol engine/7DCT combo, pumping out 150kW at 6500rpm and 300Nm from 1450-4500rpm. Tipping the scales at 1525kg for 98.4kW/tonne, its 0-100km/h time is 7.3s and top speed is 250km/h.

Want more? Stretching to the M235 xDrive sadly doesn’t mean a 3.5-litre in-line six, but a modified B48 2.0L/7DCT duo, delivering 233kW at 6500rpm and 400Nm from 2000-4500rpm to all four wheels. Result? Weighing just 50kg more than the 220, it boasts a heady 148kW/tonne, for a 0-100km/h of just 4.9s and a 250km/h v-max.

As with all of the UKL2/FAAR transverse-engine front-to-AWD platform models from non-electric Minis through to sub-X3/3 Series BMWs, you’ll find MacPherson-style struts up front and a multi-link independent rear end out back.

If you’re reading this outside of Australia, you may notice that none of the current F74 models offer mild-hybrid tech, in contrast to their European counterparts. And don’t go expecting any manual gearboxes either, unfortunately.

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.

OK, so is the 2 Series Gran Coupe cheap to run?

BMW reckons the 218 and 220 will average 6.3 and 6.7 litres per 100km, which means combined average carbon dioxide emissions ratings of 143 and 152 grams/km respectively.

Filling the 49L fuel tank with 95 RON premium unleaded, that translates to around 775km in the 218, and 730km in the 220 between refills.

Predictably, the M235 xDrive uses more, at 7.7L/100km for a CO2 rating of 176g/km. That’s a distance of about 635km.

Over our launch run, which took us from Sydney’s Circular Quay to Wollongong, the 218’s trip meter was reading in the high 8s and about 10 for the M235.

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.

Earlier, we mentioned that the 2 Series Gran Coupe is way more expensive than fine alternative sedans like the Mazda3 and Toyota Corolla.

And while that still stands, there is a remarkable solidity and refinement difference between those and the BMW that helps justify the premium. And nowhere is this more evident than from behind the wheel.

Sat on body-hugging seats and clutching that (too chunky) steering wheel, there is a sense of sporty occasion, backed up by quality trim and an aroma of expensiveness.

For a turbo three-cylinder car weighing 1.5 tonnes, the 218 does a lot with a little, offering spirited off-the-line acceleration and pleasingly lag-free throttle responses at lower speeds. You’d never call it fast, but it is a quick point-to-point urban mover. Only the unavoidable three-pot thrum lets you know you’re in the lowest mechanical spec. And, also, the delay at freeway speeds in building momentum when overtaking.

Which is why, for less than five per cent extra, the 220 with the 2.0-litre four-cylinder turbo would probably make a better buy. Sadly, that isn’t on sale yet in Australia, so we missed out on driving it during the Sydney launch. But in the scores of other BMWs and Minis we’ve tested this in, it’s a cracking little powertrain.

Whether the big leap (nearly $25K worth) to the M235 is worth it depends on how fast you drive and how much you value/need AWD. This is a terrifically muscular machine, since it provides rapid performance via a tidal wave of power, even with the lightest flex of your right foot. On-point and on-brand, this fun and fiery flagship possesses the grand-touring spirit that the rakish design and tech-heavy engineering promise.

To that end, in both the 218 and M235, the steering makes the driver feel connected to the car, resulting in precise and controlled handling. The driver-assist safety tech is beautifully calibrated and nuanced in its intervention, and the brakes are second-to-none.

What is also on-topic for a BMW is the firm suspension, despite the adaptive dampers fitted as standard equipment.

It isn’t stiff or overly uncomfortable, but bumps are certainly always felt, and they’re accompanied by fairly constant road-noise drone over some surfaces.

As such, you’re constantly reminded that dynamic athleticism is the priority here, rather than sumptuous comfort. We’ve experienced much worse from BMW, but a magic-carpet ride isn’t what’s in store for the 2 Series Gran Coupe owner.

So, what’s our verdict then? The 218 is a rorty little tryer that never fails to involve the driver, while the M235 ushers in an elevated level of acceleration, grunt and grip. We suspect that the 220 will be the Goldilocks-zone happy medium.

For (largely) better as well as for (occasionally) worse, these drive and feel like a BMW should.

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.

The Alpina B7 comes with all of the BMW 750Li's safety equipment – this includes AEB, lane-keeping assistance and lane-departure warning, blind-spot warning, active cruise control, night vision with object recognition, auto parking and surround view camera.

Along with the suite of airbags, there's traction and stability control and ABS, as you'd expect.

The 750Li and B7 have not been given an ANCAP score.

Here, however, is where BMW can do a bit better.

While the five-year/unlimited-kilometre warranty is where most premium brands are, it falls short of several Asian alternatives. Roadside assistance is for just three years and there is no capped-price servicing.

Service scheduling is also condition-based, meaning the vehicle will alert the driver when a service is imminent. This may not suit everybody, and we always recommend at least every 12 months or 10,000km, just to be on the safe side.

BMW does offer pre-paid service packs that take in basic maintenance for the first five years at $2369 or $3782, including brake-pad replacement, which works out to be about $475 and nearly $760 annually respectively. There is also a cap on mileage during that time frame: 80,000km.

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.
