Subaru Forester vs BMW M8

What's the difference?

The MY26 Subaru Forester packs plenty of punch in terms of standard features, a roomy and functional interior and overall driveability. Sure, it’s not the most exciting vehicle to drive on- or off-road but to get stuck on that is to miss the point entirely. This is a decent all-rounder with a solid background and an AWD system that long ago set the gold standard for vehicles of this type.

In a tough mid-size SUV market segment aimed more at those intent on driving through car parks rather than adventuring through national parks, the Forester offers greater versatility than most and should not be ignored.

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).

This Forester is 4655mm long (with a 2670mm wheelbase), 1830mm wide and 1730mm high.

The new generation retains more than enough of the previous Forester – blocky profile included – to remain clearly recognisable.

Traditionalists may chafe at the slicker, more citified appearance of this Forester over previous generations but the overall package is inoffensive enough to not elicit any howls of outrage from passers-by on the street.

The Forester’s interior maintains a similar cabin look and feel as before but with a 11.6-inch portrait-oriented multimedia touchscreen dominating up front, a mix of physical and on-screen buttons, as well as soft-touch surfaces and durable plastics.

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.

The Forester is quite roomy for a mid-size SUV and this is the top-spec variant so there’s leather everywhere.

The interior layout is neat and tidy and lands firmly on the correct side of being practical and familiar, with all controls easy to locate and operate.

The touchscreen offers mostly simple intuitive functionality with infrequent need to cycle through numerous menus and sub-menus to access what you want.

The aforementioned mix of physical and on-screen buttons, as well as soft-touch surfaces and durable plastic are welcome here because, you know... real life.

The front seats offer ample support and the driver is able to dial-in their preferred position via power controls on the eight-way power-adjustable seat (with dual memory). The front passenger has an eight-way power-adjustable seat. Both seats are heated and ventilated.

The 60/40 split folding second-row seats aren’t too shabby either, in terms of comfort and amenities, with a fold-down arm-rest with cupholders and directional air vents etc.

Cargo volume is 496 litres (with rear seat in use) and 1174 litres (with the rear seat down, 1667 litres to ceiling.

The tailgate is powered and hands-free with a kick sensor (apparently). But I never tried that, instead opting for the tailgate-mounted button to open and close it.

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.

The Forester has the line-up’s 2.5-litre four-cylinder naturally aspirated boxer engine (producing 136kW at 5800rpm and 247Nm at 3700rpm) matched to a constantly variable transmission (CVT), which some people detest, and some people couldn’t give a rat’s whether it’s there or not.

Also onboard is Subaru’s all-wheel drive system, driving modes (including 'Normal', 'Deep snow/Mud', and 'Snow/Dirt') and 'X-Mode' “that constantly monitors the traction available to each wheel and centralises the control of key components including the engine, transmission, drivetrain and brakes to help manage slippery conditions”, according to Subaru.

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.’ 

Official fuel consumption on the combined (urban/extra-urban) cycle for the Forester is 7.9L/100km and it uses 91RON 'standard' unleaded petrol at a minimum.

On this test, I recorded 8.1L/100km. But fuel consumption was as low as a dash-indicated 1.7L/100km while driving the Forester with adaptive cruise control engaged.

The Forester has a 63-litre fuel tank, so, going by our on-test fuel-use figures you could reasonably expect a driving range of almost 780km from a full tank. However, as with any vehicle, once you’ve loaded the Forester with any real-world burdens (e.g kids, dogs, camping gear, etc) you’ll soon see the fuel consumption increase.

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.

The Forester feels comfortable and composed on sealed surfaces and offers some degree of dynamism to the driving experience – so in line with previous generations.

It feels more refined, sharper to steer and more responsive than before. There’s ample visibility to the front but a substantial B pillar obscures the driver’s vision back over their right shoulder.

The Boxer engine and CVT work well together, power and torque outputs are more than adequate in this package, and that much-maligned transmission is not intrusive if the Forester is driven with care and common sense.

However, acceleration from a full stop is sluggish.

The suspension set-up – MacPherson struts up front and double wishbones at the rear – yields a firm but not jarring sense of ride and handling.

The 1662kg Forester proved nimble to manoeuvre around the Big Smoke, the suburbs and in the bush (more about that soon) with a neat 10.8m turning circle.

All-wheel drive vehicles are capable of tackling off-road adventures in their own right but, for safety’s sake, AWD drivers should avoid anything beyond well-maintained dirt tracks in dry weather. AWD cars are designed for use on bitumen roads with some dirt or light-duty off-road use.

And so it was with our test of this Forester. On-test off-road terrain equalled firm-packed sand and gravel/dirt bush tracks in dry weather, although we did drive through one shin-deep mudhole with no trouble.

The Forester has a listed 220mm of ground clearance, the suspension held up well over a brief stint on mild corrugations and Subaru AWD proved more than up to the task when things became a little trickier, providing improved grip and traction in slippery conditions that demanded to be driven at very low speeds.

If push comes to shove, it’s capable of more than light off-roading, but the Forester’s ground clearance and off-road angles ultimately limit its off-road capabilities.

The Forester’s 'all season' tyres – Falken Ziex Z001A A/S (225/55 R18 98V) – are fine for light to moderate off-roading but anything more difficult than that and you’ll need to get a set of more aggressive all-terrain tyres. It does have a full-sized spare onboard.

It has maximum towing capacities of 750kg (unbraked trailer), 1800kg (braked) and a maximum towball download of 180kg. GVM is 2223kg; GCM is 4023kg.

Some niggles: The driver awareness system is annoyingly over-reactive.

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. 

The MY26 Subaru range is covered by a five-year/unlimited kilometre warranty, five-year/75,000km capped price servicing, and 12 months roadside assistance.

A service is required every 12 months or 15,000km, whichever occurs soonest. After your free “1 Month Health Check and Chat”, cost per service is $347.95 (at the 15,000km/12 month mark), $520.45 (30,000km or 24 months), $393.10 (45,000km or 36 months), $679.30 (60,000km or 48 months) and $358.20 (75,000km or 60 months). Average over the five years is $459.80.

Subaru Australia has more than 140 dealerships across the country with a decent spread over metro and regional areas. Foresters may be serviced at those dealers or by approved mechanics.

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.
