BMW M240I vs BMW 8 Series

What's the difference?

When BMW is on a roll, the world needs to watch out.

And, as our Thundernight metallic-hued M240i so literally demonstrates, its purple patch continues after a string of modern marvels like the latest 4 Series and iX, distilling the essence of compact sports coupe and luxury cruiser with dizzying confidence.

Joining the pantheon of back-catalogue greats like the 2002ti and 330Ci, we're missing it already now that the keys have been returned. Isn't that the true sign of the quintessential BMW experience?

With dramatic looks, a luxurious spec, and impeccable quality, the BMW M8 Competition Gran Coupe remains supremely well controlled as it delivers eye-widening performance and amazing dynamics. But there’s an ‘edge’ to the experience you need to be ready for. If I was determined to head for the Aussie ‘fast lane’ in a BMW 8 Series Gran Coupe I’d opt for the M850i and pocket a lazy $71K (enough for a cheeky M235i Gran Coupe to add to your collection).

What is happening with BMW design? It's as if the Germans have run out of ideas.

Though we're eternally grateful it exists, the G42 is the least pretty of the three 1 and 2 Series coupe generations, as well as the most aggressively styled. All the usual macho tropes are present – cab-backward long-bonnet/short boot silhouette with an exaggerated dash-to-axle ratio, huge front air intakes, bulging bonnet and diffuser-heavy rear end.

There's also a beady eyed look to this M240i, with its squinty headlights and angry tail-light shapes further piling on the attitude. It's a far cry from the simple elegance of the E82 original, let alone the classic E30 of the Eighties. We wonder how much extra the M2 version will be when it surfaces later on.

That said, the G42's design is in keeping with something wearing an M-something-something prefix. In the optional purple of our press car, it certainly turns heads. That said, in the Bangle era, BMWs didn't have to rely on paint to do that.

Bangle, by the way, refers to BMW's late '90s/early '00s head designer Chris Bangle, an American with a bold aesthetic, scant regard for tradition and a taste for the controversial. His effect on vehicle styling, starting with the 2001 7 Series, is still felt today.

Dimensionally speaking, comparing the length/width/height/wheelbase measurements of the M240i (4548mm/1838mm/1404mm/2741mm) with a 2000 E46 330Ci (4488mm/1757mm/1369mm/2725mm) shows how today's coupe is palpably larger.

Over the previous (F22) 2 Series, the newcomer is 105mm longer, 64mm wider and 28mm lower; the wheelbase has been stretched by 51mm, while the front and rear tracks are 63mm and 35mm further out, respectively. Result? More space inside for today's lucky occupants.

Want to start a vigorous car enthusiast discussion (more a verbal punch-up)? Simply ask whether a four-door car can be a coupe.

Traditionally, the answer is no, but over time numerous automotive brands have applied that description to cars with more than two doors, including SUVs!

So, here we are. A four-door ‘Gran Coupe’, and the M8 Competition version retains the smoothly tapering turret and frameless side glass that help give selected BMW four-door models the same swoopy, coupe look.

At close to 4.9m long, a fraction over 1.9m wide, and under 1.4m high, the BMW 8 Series Gran Coupe has a firmly planted, low-slung, wide-track stance. Always a subjective call, but I for one, think it looks stunning, especially in our test car’s ‘Frozen Brilliant White’ matt paint finish.

In an era of comically oversized BMW grilles, things are relatively under control here, with a bright black finish applied to that ‘kidney grille’, as well as the huge front bumper air intakes, front splitter, front fender vents, exterior mirrors, window surrounds, 20-inch rims, lip spoiler on the boot, rear valance panel (incorporating a functional diffuser), and quad exhaust tips. The roof’s black, too, but that’s because it’s made of carbon-fibre.

Overall the M8 Competition Gran Coupe is a compelling combination of strong, confident character lines along the bonnet and lower flanks, with tightly wrapped curves following the high hip line, and more organically irregular, yet distinctly BMW shapes in the head- and tail-lights. 

The interior is a beautifully balanced design with a broad centre console sweeping up to the middle of the dash and wrapping around to focus on the driver, in typical BMW fashion.

 The multi-adjustable sports front seats are immaculate, with high-end quilting in the centre section matching a similar treatment in the doors. The dark grey (full) leather trim is offset by carbon and brushed metal trim elements for a cool, calm and focused feel.

Crack the bonnet open and a spectacular ‘BMW M Power’ carbon cover dressing the top of the engine is guaranteed to impress friends and family.

Interior dimensions may not be paramount to most coupe purchasers, but a stylish one with quality fittings and generous equipment levels certainly is, and here the M240i is bang-on brand.

For a compact two door, the M240i is pleasingly accessible. Long doors and a tallish roof help entry/egress, into a 2+2 cabin that obviously prioritises front-seat occupants. And it does that exceedingly well.

There's space to stretch – even if you're two metres tall – up front, as long as the rear seats aren't occupied, as a result of generous leg and shoulder room, while headroom should also be sufficient, even with the sunroof fitted. We're talking about a small coupe, remember, so that's impressive.

Vision out isn't as bad as you might imagine, either, due to the airiness that the elongated side windows provide. There are blind spots, though, with the B-pillar being the worst, but at least the extensive camera and sensor network surrounding the car provide reassuring back-up.

The handsome M Sport front seat option ($2000 extra) look like they mean business, providing all the comfort, support and adjustment most occupants will ever need. They're firm enough when you need them yet restfully supple all the time. Backed up by a multitude of electronics, both buckets will brace people of pretty much all sizes, while the driver has the luxury of two memory settings that also take in mirror positions.

Remember how the new 2 Series comes via Mexico? You'd never know it wasn't built in Germany, from the solid build quality and expensive materials to the extremely welcome absence of squeaks and rattles. No area exposed to the occupants looks or feels cheap.

Also meeting expectations is the dashboard itself, which is essentially a scaled-down replica of every recently released BMW – futuristic and fabulous iX aside – since the current (G20) 3 Series in 2018 broke the Bangle-era curse of disappointing new-millennial models.

If you're hoping for a return to classic analogue instrument dials, forget it. The M240i's instruments are modish electronic items, providing plenty of vehicle and driving data, and supported by an excellent head-up display. Like the switches and buttons, they're easy to fathom, with little familiarisation required.

As we've said repeatedly in other BMW reviews, the iDrive multimedia controller is amongst the best in the business, responding instantly to inputs. The other basics – ventilation, storage, driving position – are also first class. Nothing to complain about here. The company is on a good thing and it's sticking with it.

Accessing the rear seats is aided by electrified front seats that slowly whir forward, to provide a big-enough aperture for your medium-build 178cm tall tester to squeeze in.

Once sat, with legs splayed apart, there's just enough space for another person of similar height and proportions, as well as surprisingly decent levels of vision thanks to the narrow front bucket seats and extended rear glass area, to offset any feelings of claustrophobia.

BMW has also provided several welcome amenities, including face-pointed rear vents with full single-zone temperature control to serve two occupants back there, armrests (with the centre fold-down item also packing in a pair of cupholders), reading lights and coat hooks.

Sadly, however, the rear windows do not retract, and the thick door pillars are fixed, so you cannot enjoy a pillarless hardtop experience. That's what the M4 coupe (and convertible too) is for.

While rear-seat space is adequate, with enough room for shoulders, thighs and feet if the front-seat occupants don't mind raising the cushion a little, the backrest is too upright to be considered comfortable on longer journeys. At least the low cushion is scalloped enough to provide some support, though, again, not over extended periods.

That rear backrest folds, by the way, to a 40/20/40 split, providing access into the 390-litre boot while still able to accommodate a single passenger. The lid opens up and wide, offering up a long, flat and wide space for storage. Along with a 12V outlet and tie-down hooks, you'll find a tyre-repair kit, since no spare wheel is carried.

Of the M8 Competition Gran Coupe’s 4867mm overall length, 2827 of it sits between the front and rear axles, which is a pretty healthy wheelbase for a car this size (and 200mm more than the 8 Series two-door coupe).

Space up front is generous, and one upside of a four-door, rather than two-door coupe, is you’re not struggling quite so much for space to get in and out when parked next to other cars.

Once inside, there’s plenty of storage up front, with a large lidded box/armrest between the front seats, twin cupholders in the centre console, as well as another covered area for wireless phone charging and extra bits and pieces in front of that. Long door pockets provide space for bottles, and the glove box is a decent size. There’s 12V power as well as USB sockets for media connection, with charging outlets in support.

At first glance you’d swear the rear seat was designed as a two-seater only, but when push (literally) comes to shove a centre passenger can squeeze in, legs straddling the rear console.

In terms of legroom, at 183cm (6’0”) I could sit behind the driver’s seat set for my position with knee room to spare, but headroom is another matter, with my noggin making solid contact with the soft Alcantara headlining. It’s the price you pay for this car’s racy profile.

There’s a neatly trimmed storage box and two cupholders in the fold-down centre armrest, plus door pockets with enough room for small bottles. The rear console houses dual climate controls, twin USB power sockets, and a small oddments tray, as well as buttons for the optional rear seat heating fitted to our test car ($900).

The 440-litre boot is a bit like the car itself - long and wide, but not very high. The rear seat split-folds 40/20/40 if you need more space, and the boot lid is automatic with a hands free function. But don’t bother looking for a spare of any description, a tyre repair kit is your only option.

At $349,900, before on-road costs, the BMW M8 Competition Gran Coupe sits in an interesting part of the upper-luxury, high-performance market, the unifying theme being a forced induction V8 engine under the bonnet. 

On price, it lines up almost exactly with Bentley’s twin-turbo Continental GT V8 ($346,268), but that’s a more conventional, two-door coupe. 

If it’s four doors you’re after, some compelling options, within shouting distance of the M8’s price, include the supercharged V8 Jaguar XJR 575 ($309,380), twin-turbo V8 Maserati Quattroporte GTS GranSport ($299,990), and the presidentially powerful and imposing twin-turbo V8 Mercedes-AMG S 63 L ($392,835).

But, arguably, the competitor that lines up best in terms of intent, performance, and personality is Porsche’s Panamera GTS ($366,700). You guessed it, a twin-turbo V8, also designed to prowl the autobahn’s left lane. 

So, in this exalted company you need to bring your quality and features A-game, and the M8 Competition Gran Coupe doesn’t disappoint. 

Running through all the car’s standard equipment would be a tedious exercise, if only for the sheer volume of features, and hopefully, the following highlights package will give you a feel for the level we’re talking about here.

Aside from copious amounts of active and passive safety tech (covered in the Safety section) this brutal Beamer features, four-zone climate control, configurable ambient (interior) lighting, keyless entry and start, ‘Merino’ leather trim covering the seats, doors, dash, M steering wheel, and gearshift, ‘Anthracite’ Alcantara headlining, 20-inch alloy rims, active cruise control, a digital instrument panel, head-up display, and laser headlights.

The electrically-adjustable sports front seats are ventilated and heated, while the leather-trimmed steering wheel, front centre armrest, and even the front door armrests can also be dialled up to a toasty setting.

You can also add a 10.25-inch multimedia display featuring navigation (with real-time traffic updates), Apple CarPlay and Bluetooth connectivity, as well as gesture control and voice recognition. The exterior mirrors are heated, folding, and auto-dimming. The Bang & Olufsen surround sound audio system boasts 16 speakers and digital radio.   

There’s also a digital dash display, panoramic sunroof, rain-sensing wipers, soft-close doors, power sunblinds on the rear, and rear side windows, and a l-o-t more. Even in this price range, that standard fit-out is impressive.

As with all of our current favourite BMWs that aren't electric on full-fledged M cars, the M240i is fitted with a variation of the divine B58 engine – a 2998cc 3.0-litre double overhead cam direct-injection turbo I6. It delivers 285kW at a heady 6500rpm, and 500Nm of torque between a low 1900rpm and 5000rpm.

A kerb weight of 1690kg (200kg more than the 220i equivalent) means the M240i's power to weight ratio is about 169kW/tonne, which may explain why it can manage the 0-100km/h time in 4.3 seconds. V-max is 250km/h.

Power is channelled to all four wheels continuously via an eight-speed M Steptronic transmission, while the AWD system features a differential to help transmit torque to all four wheels more cleanly.

Controlling all those outputs, the M240i's suspension consists of a two-joint spring strut front and a five‑link rear axle arrangement, with M Sport suspension including variable sport steering, additional front axle struts, M Sport brakes, M Sport differential at the rear axle and adaptive M suspension with electronically controlled dampers.

The M8 Competition is powered by an all-alloy, 4.4-litre twin-turbo V8 engine, featuring direct-injection, as well as the latest version of BMW’s ‘Valvetronic’ variable valve timing and ‘Double-VANOS’ variable camshaft control, to produce 460kW (625hp) at 6000rpm, and 750Nm from 1800-5800rpm.

Designated ‘S63’, the engine’s two twin-scroll turbos are located, along with a cross-bank exhaust manifold, in the engine’s (90-degree) ‘hot vee.’ 

The idea is consistent transmission of exhaust energy to the turbos for improved response, with the reversal of usual practice completed by inlet manifolds positioned on the engine’s outer edges.

Drive goes to all four wheels via an eight-speed ‘M Steptronic’ (torque converter) auto transmission with ‘Drivelogic’, and dedicated oil cooling, as well as BMW’s ‘xDrive’ all-wheel drive system.

The xDrive set-up is built around a central transfer case housing an electronically-controlled, variable multi-plate clutch, with front to rear drive distribution set to a default 40:60 split.

The system monitors multiple inputs including, wheel speed (and slip), acceleration and steering angle, and is able to vary the ratio up to 100 per cent rear thanks to the ‘Active M Differential.’ 

Over exactly 503km of city, suburban, freeway and performance testing, we managed a credible 9.6 litres per 100km – and that was with the air-con on  constantly and regular visits to the 7000rpm rev limiter. No horses were spared in our quest to properly assess this vehicle.

BMW's official combined-average claim for the Euro 6d-rated M240 is 8.0L/100km flat – and 6.6L and 10.3L in the Extra Urban and Urban runs – for a carbon dioxide emissions average of 185 grams/km.

The small fuel tank swallows just 52 litres of E10, 95 or 98 RON (as tested) premium unleaded petrol, meaning an average of 650km between refills is possible.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 10.4L/100km, the M8 Competition emitting 239g/km of CO2 in the process.

Despite the standard auto stop/start function, over a week-long combination of city, suburban, and freeway running we recorded a (dash-indicated) average of 15.6L/100km.

Pretty thirsty, but not outrageous when you consider this car’s performance potential, and the fact that (purely for research purposes) we exploited it regularly.

Recommended fuel is 98 RON premium unleaded, and you’ll need 68 litres of it to fill the tank. That equates to a range of 654km in line with the factory claim, and 436km using our real-world number as a guide.

In a word, invigorating.

Stuffing a big old engine in a little-ish car is always an exciting recipe for thrills, and the M240i Coupe does not disappoint.

Press the start button, and the sublime B58 3.0-litre turbo I6 growls into life, setting a rich tone for the level of performance as well as sophistication that's coming.

Even in Eco mode, off-the-line acceleration is stirring, with a hefty shove if you're in a hurry, or a brisk pace if you just long to just take it easy, defined by smooth upshifts from what remains one of the world's greatest-ever automatic transmissions.

That said, Normal is the default operating setting, and here the M240i can take on a Jekyll and Hyde split-personality, that goes well beyond simply possessing a strong throttle response accompanied by a soaring exhaust note. The engine sings sweetly even right up to 7000rpm, while the gearbox is uncanny in its ability to always be in the correct gear, yet will simultaneously hold each ratio in manual mode (via the shifter or paddles) if the driver needs to go hell-for-leather.

Speaking of which, in Sport mode, the 3.0-litre turbo goes into red alert, taking on a louder and more muscular mood, as it roars along with frenetic yet effortless speed. What seems like 90km/h can, in fact, be very much more, and with plenty of extra oomph in reserve.

It's so typical BMW that purists affronted by some of the brand's other niche offerings of late will cry with joy that the art of making a sports coupe has not been lost in Bavaria after all.

And that's before the first turn of that fat little steering wheel. Here the 2 Series Coupe's 3 Series-derived CLAR architecture's DNA is immediately obvious, providing subtle balance and an immersive connection to go with all that bolshy brawn.

The M240i will glide along precisely where pointed, sticking steadfast to the tarmac while cornering at speed without breaking a sweat. That mechanical rear diff helps provide both alacrity and reassuring control. Yes, it remains weighty and planted when punted relentlessly through tight corners, but it's also not as heavy-feeling as before.

Being AWD, there's grip galore to rely on for security, yet the M240i still seems deliberately rear-drive biased in its set-up, so the driver can hang the tail out if wanted with gradual ease in Normal, or with a little more of a sideways flick in Sport. The modes are configurable so the level of engine, steering and suspension responses can be tailored as desired, meaning that in the racy Sport Plus setting, with stability and traction controls on hold, the full oversteer experience is possible if you're game/brave/silly enough.

This car's brilliant performance is also down to incredibly dependable and nuanced braking, adding another layer of driver enjoyment, since it can pull up hard and fast if need be without drama or fuss.

So, it's no surprise to learn that an M-Sport-enhanced BMW can be a deliciously fast and limber along a mountain road.

But the real progress over the old F22 is just how suave and polished the G42 is if you're tired and stressed, isolating its occupants from the rigours of rubbish road surfaces. Kudos to the 'Adaptive M Suspension' and its adaptive dampers for this, for they're standard M240i fare. The resulting cushy ride completely broadens the dynamic bandwidth of this compact sports coupe, making it an everyday commuting proposition.

Ultimately, it's a bit of a struggle to find fault in the 2 Series' drivability and dynamic make-up. The usual Euro luxury car bugbear of too much coarse-chip tyre noise applies, but as this is a sports coupe, that's not such a big deal here. Even wind noise levels are subdued – all the better to drink in that glorious turbo engine wail.

BMW, you got the M240i delightfully right.

There’s something teutonically symmetrical about the way the M8 Competition Gran Coupe delivers its prodigious thrust.

Peak torque of no less than 750Nm is available from just 1800rpm, remaining on full song across a broad plateau all the way to 5800rpm. Just 200revs later (6000rpm) peak power of 460kW (625hp!) takes over to finish the job, with the rev ceiling sitting just over 7000rpm.

That’s enough to slingshot this 1885kg bruiser from 0-100km/h in 3.2 seconds, which is supercar fast. And the engine and exhaust noise produced by the 4.4-litre twin-turbo V8 during such rapid acceleration is suitably brutal, courtesy of electronically-controlled flaps in the system opening up. 

On a more civilised drive you can reduce the exhaust noise via an ‘M Sound Control’ button on the centre console.

The eight-speed auto is fast and positive, especially in manual mode, which dials up the fun via wheel-mounted paddles. And when it’s time to direct this car’s forward momentum into lateral movement BMW has brought in the engineering heavy artillery.

Despite its frameless door body structure the M8 Competition Gran Coupe feels solid as a rock thanks in no small part to its ‘Carbon Core’ construction, using four primary components - carbon-fibre-reinforced plastic (CFRP), aluminum, high-strength steel, and magnesium.

Then the ‘Adaptive M Suspension Professional’ (with active anti-roll stabilisation), the tricky xDrive continuously variable AWD system, and active M Sport diff combine to keep everything under control.

Suspension is a double wishbone front, five-link rear arrangement, with all key components in alloy to minimise unsprung weight. In concert with the electronic wizardry on-board, it helps keep the M8 buttoned down with only modest body roll in enthusiastic cornering, as the rear-biased AWD system seamlessly distributes drive to the axle and wheels that can make best use of it.

The price you’ll pay for the track-ready tune is in compromised ride comfort. Even in the ‘Comfort’ setting, the M8 Competition is firm, and feels corrugations and imperfections to a surprising degree.

An alignment of the BMW 8 Series planets left me with the keys to this car and the M850i Gran Coupe (also using the Carbon Core body) at the same time, and the difference between their softest settings is appreciable.

Also be aware that at 12.2m the M8 Gran Coupe’s turning circle is substantial, and it’s just as well all that camera, sensor and self-parking tech is available to help you guide this ship into port.

The M8’s electrically-assisted, variable-ratio steering features an ‘M’ specific calibration to deliver satisfying precision and good road feel. But in similar fashion to the ride a noticeable amount of unwelcome feedback comes through to the wheel.

The fat Pirelli P Zero rubber (275/35 fr / 285/35 rr) grips hard, and the monster brakes (ventilated all around, with 395mm rotors and six-piston calipers up front) wash off speed without fuss or fade.

But overall, you’ll have to live with a less refined drive when you sign on for the M8 Competition. Straight away it feels faster but lacks the M850i’s lighter touch. No matter which drive or suspension mode you select, responses are more aggressive and physical.

To fully explore and enjoy the M8 Competition’s abilities it feels like the race circuit is its most appropriate habitat. On the open road, the M850i is all the Gran Coupe you’re going to need.

The BMW M8 Competition Gran Coupe hasn’t been assessed by ANCAP or Euro NCAP, but that doesn’t mean it’s lacking in terms of active and passive safety tech.

As well as expected crash avoidance features like stability and traction controls, this M8 features the ‘Driving Assistant Professional’ suite which incorporates active cruise control (with ‘Stop & Go’ function) and ‘Night Vision’ (with pedestrian recognition).

Also included are AEB (with pedestrian and cyclist detection), ‘Steering and Lane Control Assistant’, ‘Lane Keeping Assistant’ (with active side collision protection”, an ‘Evasion Assistant’, a ‘Crossroads warning’, ‘Wrong-way warning’, as well as front and rear cross traffic alert.

The headlights are ‘Laserlight’ units incorporating ‘BMW Selective Beam’ (with active high-beam control), there’s a tyre pressure indicator, and ‘Dynamic Brake Lights’ to warn those behind of an extreme braking event.

Plus, M8 Competition owners score complimentary enrollment in the BMW Driving Experience Advance 1 and 2 courses.

To help guide your parking efforts there’s a hi-def reversing camera (with panoramic view monitor), rear parking distance control, and ‘Reverse Assist’. But if all else fails the car can park itself anyway (parallel and perpendicular).

If all of that isn’t enough to avoid an impact, you’re protected by 10 airbags (dual front and front side, knee bags for the driver and front seat passenger, as well as side airbags for the second row, and curtain airbags covering both rows).

An automatic emergency call function contacts the BMW call centre for connection to relevant services in the event of a crash. And as has been the case with BMW since the dawn of time, a first-aid kit and warning triangle are on-board. 

Trailing all of its main luxury car rivals (except Porsche) by two years, BMW only offers a three-year/unlimited kilometre warranty, as well as three years of roadside assistance.

BMW says its vehicles' servicing is condition-based, depending on how they're driven and other factors, with a dash warning appearing to let the driver/owner know when it's time. We advise servicing your M4 annually or at every 10,000km

No capped-price servicing system is offered. However, as long as the first one is paid for before the first service on a new vehicle, the 'BMW Service Inclusive Basic packages' is available at extra cost, covering scheduled servicing for three years/40,000km or five years/80,000km. A 2 Series should cost from $1700 for the five-year/80.000km package.

BMW offers a three year/unlimited km warranty, which is at least a couple of years off the mainstream market pace, and lagging other premium players like Mercedes-Benz and Genesis, both sitting at five years/unlimited km.

Roadside assistance is included for the duration of the warranty period, and the standard ‘Concierge Service’ provides everything from flight information, to global weather updates, and restaurant recommendations, from a real human.

Technically, service is ‘condition based’ with the car telling you when it’s time to hit the workshop, but you can use every 12 months/15,000km as a guide.

BMW Australia offers ‘Service Inclusive’ packages that require customers to pre-pay for servicing, allowing the cost to be covered off in finance or leasing packages and reducing the need for concern about paying for maintenance further down the track.

BMW says there are different packages available, from three to 10 years, or between 40,000 and 200,000km.
