What's the difference?
Phwoar. Mate!
Or should I say, M-eight-fifty-I. That’s right. This is the all-new, 2020 BMW M850i Gran Coupe, the first ever example of its kind. It’s a big, long, luxury, sporty, coupey thing. And it’s gorgeous.
The BMW 8 Series 2020 range includes this new Gran Coupe body style, and also the Coupe and Convertible models. This particular model, the M850i xDrive Gran Coupe, is essentially BMW’s answer to, say, the Audi RS7. Or one of the many Porsche Panamera variants. Or the Mercedes-Benz CLS or Mercedes-AMG GT 4 door Coupe.
Like those cars it has svelte looks, striking dimensions and a sledgehammer engine under its long, shapely bonnet. This is first ever 8 Series Gran Coupe, as it essentially stands in place of the existing, now defunct, 6 Series Gran Coupe. But it’s bolder, bigger and more brutal - just take note: this isn’t a full-scale ‘M8’ Gran Coupe. It has more of a luxury speed cruiser angle to it, arguably like a Mercedes-AMG CLS 53, not the full-fat AMG 63.
The question is, then, should you buy it over one of its established rivals?
Let’s figure it out together, shall we?
The EQE is more than an important car for Mercedes. Not only is it the German titan’s latest electric offering, on all-new underpinnings, but it represents the very future of its passenger car range.
It adopts a completely new shape and design language, but it also puts its fastest foot forward, launching with the 53 AMG variant first in Australia, by the end of 2022.
We travelled to Europe to sample it for the first time ahead of its Australian arrival to find out what the future of Mercedes feels like, but also how its go-fast AMG division has managed to leave its mark on an electric car.
If you’re the sort of buyer who wants a car that signifies a lifestyle that is ‘large and in charge’, the BMW M850i Gran Coupe could be just the thing for you. It isn’t as showy as some of its competitors, and mightn’t reach the same levels of excitement as those cars either - but it is a convincing offering in its own right, and a beautiful piece of design at that.
In the wild new world of fully electric cars there isn’t really an ‘average’ of what to expect. If there was, I’m sure the EQE 53 would exceed it. Its electrification brings the ambiance of a luxury car, while its performance reminds you of what AMG is capable of.
There’s a bit of the mechanical engagement of AMG missing, a relatively small boot, and some won’t be sold on the function-over-form looks, but the EQE 53 is a pleasantly surprising look at the future of fast Mercedes.
This could be BMW’s most convincing design in years. I mean, the X5 is predictably handsome, the X3 was unexpectedly muscled, and the less said about the frumpy 1 Series and busy 3 Series (apart from the wagon… drool) the better.
To my untrained but enthusiastic eye, the 8 Series Coupe is a bit too rounded over its rear haunches, and the rear screen is just a little steep - to me, that lets its dimensions down a little. But this. This is gorgeous.
I mean, you might have questions over the tail-light design, which is a theme across a few BMW models now. But there isn’t as much confrontation between horizontal and vertical graphics for this model as you’ll find one other big Bimmers, like the X7.
The M850i model has BMW Laserlight headlights, which throw a sharp beam and look menacing in their signature, while the grille and bumper are strong. The stance of the car is prominent - there’s a long body, a long wheelbase, and a long body in general. The standard wheel package consists of 20-inch rims, and they don’t look disarmingly large.
As our images show, there’s a lot to talk about when it comes interior design and finishes, but the cabin doesn’t quite benefit quite as mochas you might think it would from all that real estate. I mean, with dimensions of 5074mm long (on a 3023mm wheelbase), 1932mm wide and 1402mm tall, this is a squat, yet substantial vehicle. It’s just more cramped than you’d think inside.
The EQE is certainly a departure from the classic lines of the current E-Class sedan. Mercedes-Benz has chosen to take a completely new approach for the electric era, embracing the need for ultra-low drag designs, and a corresponding newfound love for curvaceous surfaces.
It’s fairly imposing too with enormous wheels and an abundance of panels. Needless to say some will find this new design direction challenging. It proved quite controversial in the CarsGuide office, at any rate.
I can say it looks a bit more approachable when witnessed in the metal, and the AMG branded 53s I sampled for this review added a few more much-needed points of interest to this single curve of a design.
This is particularly notable around the rear of the EQE 53 which adds a little tail spoiler and glossy rear diffuser, which help accentuate the width and terraced design of the rear window.
Around the front is a little more featureless, with the blanked-out grille losing the intricate three-dimensional appeal of this car’s combustion equivalents. There’s just something a bit plain about the EQE’s face, although Mercedes has tried to spice it up with interesting headlight clusters.
The inside is spectacular, with a smorgasbord of screens and lights to match an abundance of glossy touch-based surfaces. Some may not be sold on the over-the-top approach, but it feels as futuristic as an EV should be.
The material choices are nice, too, with soft-touch materials atop the dash, doors, and running down the centre console. The ambient lighting is particularly flashy, and works in with the consistent single-piece sort of design which makes up the whole dash.
While the LEDs might be a little too much for some, there are some more subtle detailing points, like the way the centre air vents are delicately worked into the flow of the dash, and the rotor designs of each vent at the edges are intricate pieces.
I recall a Mitsubishi designer telling me, once upon a time, that he dreamed of making ‘a big car on the outside with a very small interior’. Maybe he made the jump to BMW, because that’s pretty much the 8 Series Gran Coupe.
There aren’t many other vehicles on the market, of this size, that offer less space inside. The boot capacity, for instance, is just 440 litres. Competitors like the Audi A7 (535L) and Mercedes CLS (520L) easily outdo it - but at least this car has more boot than the Panamera (405L), though the BMW is a smidge bigger. The cargo space is large enough for a couple of overnight suitcases, but you’re hardly going to fit a family of four’s luggage for a week away.
And while we’re in the “not quite what you’d expect” column, the back seat space is hardly commodious. There’s enough space for me, at 182cm, to sit behind my own driving position, but not without wishing for a bit more toeroom, headroom and knee space.
The big centre console section eats into the space in the rear, justifying the brand’s “4+1” seating claim, and unpleasantly it has a hard plastic finish to rest your leg against. Getting in and out of the second row isn’t easy for bigger people, and it’s quite a squat down into the rear seat - it really has taken inspiration from its squashy-back-seated predecessor in that regard.
If you have smaller rear-seat occupants, however, there will be catered for with dual ISOFIX and three top-tether points, plus there are air vents with climate controls (quad zone in total), and two USB-C ports as well. There are sun-blinds on the rear windows, too, which is a plus, and there is a pair of cup holders in the fold-down armrest, and map pockets in the seat backs, too. The door pockets are near-useless, though.
The front seats score better practicality, with bottle holders in the doors, bigger and sturdier cup holders, a covered centre storage bin between the seats with a USB-C port, and a wireless phone charger (Qi) with standard USB port in front of the gear selector.
Above that is the weird, very out-of-place quick buttons (1-8) that BMW could easily do away with, and further up are the controls for the climate control (thankfully with hard buttons for fan speed and temperature), and above that is the media screen, a familiar looking 10.25-inch touch display running BMW OS 7.0.
The screen is quick and crisp, and is backed up by the rotary controller and buttons on in the centre console area. There’s wireless Apple CarPlay (now at no cost for three years), as well as a built-in SIM card for 4G data and access to the BMW Online news and weather stations, accessed through the screen.
It’s all pretty easy to use, and the sound system is excellent - the standard setup consists of 16 speakers, with DAB+ digital radio, Bluetooth and USB plus the smartphone mirroring tech, provided you don’t have an Android device, as Android Auto is still missing from BMW’s range.
It’s a nice cabin, but I couldn’t help but thinking that I’d want a little more differentiation from the lesser models in the range if I was spending this much. Especially considering the optional cost of the interior trim fitted to our test car - see below for more detail.
The EQE is plenty practical up front, with an odd SUV-like seating position providing a commanding view of the road. This seat positioning isn’t an accident or a necessity of facilitating batteries under the floor, but a deliberate design decision by the brand to try to emulate some design choices which have made SUVs so popular.
The result is surprisingly effective, but doesn’t help the view out of the rear of the car, which is a restricted letterbox aspect courtesy of a slinky roofline and tall boot lid.
Still, peering down on the road lets you position and park this large EV more easily. Adjustability isn’t bad for the front passenger, and space is healthy both in terms of width and height. One dimension which can’t be altered is the particularly tall dash height, and while this is largely overcome by the taller-than-average seat, it could be an issue for shorter drivers.
Storage is great, with a big bottle holder and bin in the doors, a huge cutaway below the floating centre console for storage, with an elastic strap for tying down objects. There are a further two bottle holders in the centre console and a bay with a wireless charger, too, and the split-opening armrest box is deep.
One of the more divisive points of this car’s practicality offering is the screen-based functions. Everything has been moved into the massive centre screen. There are no tactile buttons or dials for this car’s functions, with it all controlled through context menus.
To be fair, with the amount of real estate on offer, the touch elements can afford to be massive, and there is a permanent set of climate controls at the base of the screen, but adjusting these functions on the fly is never as easy without physical feedback.
The same goes for the touch-centric wheel controls. Benz says the idea with the four-zoned touch panels on the wheel is to offer unrivalled ability to control the car’s functions even when the wheel is at an angle, but it is also easy to accidentally hit various touch functions, and they can require some delicate action to use properly.
The back seat is impressive. It maintains the tall seating position of the front, letting you look down on the road as though you’re in an SUV, and the comfortable seating and surfaces continue. Legroom is particularly impressive, with leagues of space behind my own driving position. Headroom is even okay considering the descending roofline. It’s quite dark in the EQE 53 we tested thanks to its black-on-black trim, giving the illusion of a space which is smaller than it actually is.
Storage is good, too, with a big bottle holder in the door cards, quad-zone climate control, complete with a separate touch panel for rear passengers, adjustable air vents, and solid clamshell pockets on the backs of the front seats.
The EQE has a boot capacity of 430 litres which doesn’t seem enormous given the footprint of this car, and no doubt has a lot to do with its slinky aerodynamic design around the rear. There’s no ‘frunk’ either so this is a car perhaps more focused on driving and being driven in than its ability to carry things.
No-one could level the accusation of affordability at the BMW 8 Series Gran Coupe, as it’s one of the brand’s most expensive models.
This one, the M850i xDrive Gran Coupe, is the range-topping version for 2020, with a list price of $272,900 plus on-road costs.
Where does that plot the BMW against its rivals? It’s beyond the level that the existing Audi RS7 Sportback was (last sold in 2018 at $261,140), and the Mercedes-AMG CLS 53, which looks like a value offering at $182,740. Also, it splits the difference between and the Mercedes-AMG GT 4 door Coupe variants (GT 53: $251,140; GT 63: $351,640), and could best be considered a contemporary of the Porsche Panamera E-Hybrid AWD ($252,400) or the Panamera 4S ($316,500).
So, look - competitors might matter to you. But there’s a good chance that if you’re shopping for an 8 Series, you’ve already made up your mind that you want the BMW four-door coupe slugger. So here’s what you need to know about it when it comes to equipment.
Standard it comes with the M Sport styling pack, 20-inch M alloy wheels with run-flat tyres and tyre pressure monitoring, adaptive M suspension with active roll stabilisation, 395mm M brakes, BMW Laserlight headlights, BMW Night Vision infrared camera with pedestrian detection.
Luxury touches include soft close doors, semi-autonomous parking, panoramic glass sunroof (front opening, rear fixed), keyless entry and push-button start and electric auto tailgate, heated and ventilated front seats with electric adjustment including lumbar and bolster, leather seat trim, a 16-speaker harman/kardon sound system, 10.25-inch media screen with gesture and voice control, 12.3-inch digital instrument display, full colour head-up display, ambient lighting and rear sun-blinds.
You’re getting a lot for your money, though our tester had a couple of extras. Metallic paint is included, but no the Frozen Bluestone matte finish our car had ($2600), and the interior piano black trim elements cost $200, as well. Plus the Full Leather Merino finish in Ivory White and Night Blue - that box cost $10,200 to tick. All told, the price as tested before on-roads was $285,900.
We don’t yet know which EQE variants will be offered in Australia. The car we drove for this review, the EQE 53 AMG is the top of the range, and will be the launch variant in Australia, but the brand is yet to settle on how it will fill the line-up underneath.
Representatives said to expect at least two more Mercedes-Benz (as opposed to AMG) branded variants, with the option of a rear-wheel drive entry model and an all-wheel drive mid-grade. Whether they adopt the same spec level as the European-market EQE 350 remains to be seen.
As for the EQE 53, CarsGuide understands a price north of $200,000 is likely when it arrives before the end of 2022.
Its rivals will include other high-end four-door models like the Porsche Taycan, Audi e-tron GT, and the updated Tesla Model S. In the coming years this segment will continue to heat up with the yet-to-launch Hyundai Ioniq 6 and Polestar 5.
The EQE is fairly large, offering dimensions comparable to that of the CLS which came before it, and is quite unconventional in a host of areas.
The standard suite of equipment we sampled is impressive, too, with performance enhancements on the 53 including four-wheel steer, adaptive dampers, a performance brake package, and torque-vectoring all-wheel drive.
Massive 21-inch alloy wheels featured on our car, and there is also the option overseas for even higher performance carbon ceramic brakes.
Outside also features LED headlights, DRLs, and tail-lights, while inside impresses with the massive dash-spanning ‘Hyperscreen’ with panels for the digital dash, centre multimedia screen, and a third panel for the front passenger.
This set-up is optional on the EQE range in Europe, but we’ll have to wait and see what becomes standard for the Australian market. The car we sampled had wireless phone mirroring tech, wireless charging pads, built-in navigation with augmented reality directions, a head-up display with configurable panels, and full USB-C connectivity throughout.
Quad-zone climate also features, as does the brand’s latest steering wheel, in our case clad in Alcantara and leather trim.
The seats, even on the EQE 53 ship standard with the ‘Artico’ synthetic leather trim, although they can also optionally be upgraded to full Nappa leather. Electrical adjustment is standard for the front seats.
It’s a flashy cabin which feels primo, and little touches like unique materials for the EQ range across the dash and ambient lighting configurable to any colour you can dream up are neat, too.
Check in closer to the EQE’s local arrival time before the end of 2022 for more accurate pricing and spec, as well as the list of option packs.
If you’re going for the M850i, you’re getting the big bopper engine. It’s a 4.4-litre twin-turbo V8 petrol engine, and it isn’t short on horsepower.
The outputs for this engine are 390kW of power (at 6000rpm) and 750Nm of torque (from 1800-4600rpm). Hardly numbers to sneeze at.
And the performance figures are exceptional, too: the claimed 0-100 km/h time is just 3.9 seconds. That’s because there’s the traction of BMW’s xDrive all-wheel drive system, and shifting gears is an eight-speed automatic transmission.
For what it’s worth, your humble reviewer saw a 0-100km/h time very close to that (4.2sec).
The quoted kerb weight for this model is 1995kg.
The EQE 53 punches out huge power, with the standard car producing 460kW/950Nm from its dual electric motor set-up, or with the 'AMG Dynamic Plus Pack', producing even higher figures of 505kW/1000Nm.
Clearly, AMG’s electric vehicles will safely outrun their dramatic combustion predecessors. In fact, with the Plus Pack, the EQE 53 is capable of moving its bulk from 0-100km/h in just 3.2 seconds. Extreme for something carrying a whopping 90.6kWh of batteries under the floor.
Enhancements include torque-vectoring all-wheel drive, all-wheel steer, adaptive dampers, and the choice of standard performance brakes or a carbon ceramic package.
You can’t really expect a big V8 beast like this to be a fuel miser, and it isn’t.
The claimed consumption is 10.7 litres per 100 kilometres. Which is alright, honestly, given the sheer volume of car you’re driving.
But on my test - which consisted of more than 300km of mixed driving, including days of city commuting, some twisty mountain driving, and all the freeway floundering to get there - I saw an at the pump real-world figure of 15.4L/100km.
That’s not very efficient, and it’ll be expensive to run on the daily — yet the argument could be made that if you’re spending this much on a car, fuel costs won’t matter much to you. But with a small fuel tank capacity of 68 litres, it could become a little inconvenient as you’ll be seeing a lot of your local servo.
Electric vehicles appear to have the same issues as their combustion counterparts, in that they still drop in efficiency the more powerful you make them. In the case of the EQE 53, this means an average WLTP-rated consumption number between 20.3kWh/100km and 23.2kWh/100km.
'Thirsty' for an EV, although it is on par with the Porsche Taycan and still below Audi’s e-tron S.
When it comes to charging the EQE 53 can charge at a rate of 11kW on the AC standard, or a whopping 170kW on DC - allowing 180km of range to be added every 15 minutes. It also has the convenient option of a 22kW AC charger, a welcome inclusion if you intend to charge your car often at public outlets.
Total range for the 90.6kWh battery is 513km on the WLTP cycle.
It’s an impressive thing, this M850i xDrive Gran Coupe. But I’m just not sure who it’s trying to please.
It’s not the sort of German monster coupe-sedan that grabs you by the scruff of the neck and throws you around with its mammoth acceleration. Not unless you poke it and prod it and make it really angry.
And that might be exactly what you want to do - put it in Sport mode, sling the shifter across to sport or manual mode, hear the exhaust open up from a pursed-lip tongue-click to an open-mouth growl.
You’ll push hard on the accelerator, watch the tacho needle jolt to the redline, and if you’re in auto mode you’ll feel the transmission whipcrack as it shifts rapidly up through the gears as you’re shoved back into your seat. Before you know it you’ll be in licence-loss zone, and you won’t have even made the tyres chirp - that’s how immense the traction from the all-wheel drive system is.
You’ll brake hard into a sharp bend, and you’ll feel the front end dip and the body of the car change direction more readily than you’d think given its size as you turn in. The steering response will meet your expectation, with rapid reaction to adjustments mid corner. And the Active Roll stabilisation system will mean you’re not being thrown around in your seat, because it’s sitting flatter and truer than you might have expected - you’ll notice how it works extremely well in conjunction with the car’s torque-vectoring-by-braking system. There’ll be little weight shift or body roll to be counteracted, and that’ll inspire you to push it even harder.
Put it in manual transmission mode and you’ll rejoice that it won’t overrule you and shift up, but you’ll also feel shortchanged because it gets to the end of its limit very quickly. And when it hits redline, it emits a breathless little cough rather than a “oh maybe I should stop” rev-bounce noise.
But, if you’re like me, you might be doing all this with a niggling thought in the back of your mind that, while this car is technically really good and it’s a clinical performance car, you might just think to yourself, “I’m not having as much fun as I thought I would”.
A Mercedes-AMG would be more fun; it’d be more raucous, more of a muscle car experience. An Audi RS7 (at least the previous one) would be noisier, brasher, more theatrical than this car. And likewise, a Porsche Panamera - no matter the model you go for - would be more entertaining in the bends.
Maybe it’s just a bit too predictable - and maybe that’s a result of this car being honed for drivers who will spend more time on the Autobahn than anywhere else. I have to say, there are much, much worse (and slower) ways of getting from A to B, and the highway cruising comfort of the M850i Gran Coupe was what impressed me most.
It’s also surprisingly adept at urban driving duties, coping well with unpleasant city surfaces, though potholes can still upset things because of the stiff-sidewalled run-flat tyres. The suspension does an exceptional job otherwise, however, and I switched between the Adaptive drive mode and Comfort mode for my commuting duties. Both proved comfortable and controlled.
The M850i is by no means a failure when it comes to fulfilling the expectations you might have of a luxury sports sedan of this size. In fact, it’s close to a distinction. But I just can’t help thinking that it’s not as much an ‘M car’ as that M850i badge might have you believe it should be.
The way the EQE 53 drives was deeply unexpected. Just looking at this massive sedan, I would have expected it to feel burdened by its batteries, and with its length and shape, cumbersome in the corners. That wasn’t the case at all.
The EQE 53 feels remarkably coherent from behind the wheel. The seating position works well to give a nice view of the road, the steering feels a tad artificial but still direct with some AMG magic having worked its way in.
What surprised me most is how agile it feels. Once you gather some speed and attack some corners, this car shrinks. Control is excellent thanks to the massive tyres, all-wheel drive system, and all-wheel steering. It sounds like a lot of complexity, but you don’t notice any of it. Each system does its part to allow you to simply point the car where you want it to go at pretty much any speed. It is very impressive.
The ride feels supple, too, thanks to adaptive dampers, but offers plenty of control. The speed is Tesla-style violent. Put your foot to the floor in Sport or Sport+ mode and you’re thrown to the back of your seat as the car enters a state of warp. AMG says there won’t be a 63 version of this car, and I can’t imagine why you could possibly need anything faster or more capable than this 53 version. 1000Nm of torque!
This overwhelming number perhaps makes it more impressive that it’s hard to extract a squeak from the tyres. Sure there’s torque-vectoring magic at play, but even at full acceleration they hold on for dear life.
It also makes a noise. AMG is very specific about what went into making the soundscape for the EQE because in the electric era its performance can be achieved silently, and the brand knows full well its badge usually comes hand-in-hand with aural drama.
I stuck it in the stock mode and varied my driving from 'Comfort' to 'Sport+.' The sound builds as the car gains speed, but it also interacts with your accelerator and brake inputs, as well as being one of few EVs with a specific noise for regenerative braking. It sounds… odd.
There’s certainly a kind of drama to it, and to me, it’s better to have it as a way of gaining some feedback from the car. But, its artificial nature and loudness became a little too much for sustained driving in Sport + mode. I found the best balance in the more regular ‘Sport’ mode, or even toned down to ‘Balanced’ which puts it in the background.
This leaves quite a void, though. While the sound is welcome, and the throttle alarming, there’s just something missing from the usually brash AMG badge promise.
As an EV, the EQE 53 has three regen modes quite distinct from one another. Mercedes says the choice to have just three modes is deliberate, as it didn’t want to dilute the personality of the car with an overwhelming choice of regen. The three modes include: basically no regen, moderate regen, and the full regen, essentially a single-pedal driving mode. I preferred the strongest setting for efficiency's sake (plus it brakes for you as you let off!).
The EQE 53 is surprising in so many areas, and much more engaging to drive than its exterior visage might suggest. I’m impressed.
The safety equipment fitted to the BMW M850i Gran Coupe as standard is extensive - but this model has not yet been tested by ANCAP or Euro NCAP, so there’s no safety rating or crash test rating available.
Standard equipment includes BMW’s Driving Assistant Professional system with adaptive cruise control with stop and go in traffic, auto emergency braking with pedestrian and cyclist detection, front and rear cross-traffic alert, lane keeping assist with steering input, blind spot monitoring, “crossroads warning and evasion aid” which can help you steer away from potential danger more easily.
There’s also a comprehensive camera suite with a reversing camera, surround view and forward view camera setup which can adjust based on what part of the parking manoeuvre you’re up to. Plus if you get stuck, the reversing assistant system can remember the last 50 metres you drove and get you out of the spot. There’s also a thing called Active Park Distance Control rear, which will apply the brakes when you’re reversing if it thinks you’re getting to close to an impact.
There are six airbags - dual front, front side and curtain - with no rear side airbag protection, which seems odd in a car at this price point but is likely down to packaging.
We don’t yet know what standard safety equipment will arrive on Australian-delivered EQE variants, but you can expect a high-end suite of gear including auto emergency braking to freeway speeds, lane and blind spot assistance, driver and road monitoring tech, as well as the brand’s rather good autonomous cruise suite.
The EQE pairs the expected set of airbags with an additional driver’s knee airbag and centre airbag for some markets, as well as a second set of side impact airbags for rear passengers. There are dual ISOFIX mounts on the rear outboard seats, and expect there to be the usual three top-tether mounts in Australia, too.
Stay tuned closer to the EQE’s arrival toward the end of 2022 for more accurate specification.
BMW backs its cars in Australia with a three-year/unlimited kilometre warranty.
You may be confused if you head to the BMW site and see that M models and 8 Series models aren’t covered by BMW’s pre-pay capped price servicing plan (as I saw when testing this car), but CarsGuide can confirm that the 8 Series is indeed covered - unless it’s the real M8, not this M850i jigger.
BMW Australia has clarified that the Service Inclusive pack for five years/80,000km of maintenance cover is $2490 for Basic cover (no brakes/pads, no wiper replacement), or $5641 for the more comprehensive Plus pack. Hardly affordable, but nor’s the car.
The company uses a condition-based servicing program, too - there are no set service intervals, but the car will tell you when it needs maintenance based on how you drive it.
For what it’s worth, we ran the numbers on resale value using Glass’s Guide predictive analysis tool, and after three years/40,000km the expected retained value for this version is approximately 66 per cent - which is impressive.
Mercedes-Benz in Australia currently offers a range-wide five-year and unlimited kilometre warranty, a standard which is spreading to other premium brands.
We don’t know what the service schedule or running costs will look like for the EQE range yet, but expect it to be most affordable when chosen with a multi-year prepaid service plan at the time of purchase. Check back closer to its launch time to see the full details.
