BMW i7 xDrive60 vs Mercedes EQS 580 4Matic data comparison

BMW i7 vs Mercedes EQS data comparison
Does the real e-car slap the electronic combustion engine?

The new BMW i7, announced for November 2022, and the not much older Mercedes EQS could both come from the electrically-powered luxury sedan segment. They are also in the same league in terms of price: BMW wants to see at least 135,900 euros for the i7 in the xDrive60 version, while the Mercedes EQS 580 4Matic costs at least 135,529 euros. But as soon as you look at their photos or datasheets, it becomes clear that their manufacturers are pursuing entirely different philosophies with these flagships.


On the one hand the i7, which only reveals on closer inspection that it is not the new 7 series with only electrified combustion engines. And which, among other things, signals with its powerful grille: “Hey, my brother and I, we use the same platform, only different types of driving. If you choose me, you hardly have to get used to it!”


Pure electric platform for the EQS

The EQS is completely different. It features a decidedly rounded and aerodynamically optimized bodywork and therefore looks very different from the conventional design S-Class. Some would say: more futuristic. The design alone seems to express, “Okay, my brother is a high-tech car too. But only with all the digital gimmicks. When it comes to drive, it comes from the past, despite partial hybridization.” And this is somewhat true: Mercedes developed its own architecture for the EQS and its derivations, which was designed exclusively for electric drives from the very beginning.

Unlike the BMW i7, the Mercedes EQS uses a specially developed platform for purely electric drives.

The design of the Mercedes EQS with hatchback and large tailgate results in a sensational drag coefficient: cD 0.20 means a record for production cars. The i7 can’t keep up with the conventional three-box sedan design and small trunk lid and is a whole corner away from it with its really pretty good drag coefficient of 0.24. The first tests under real conditions must show how this affects energy consumption. On paper it doesn’t matter: according to the WLTP standard and depending on the configuration, the EQS 580 4Matic consumes between 18.2 and 21.3 kilowatt hours per 100 kilometers. The i7 xDrive60 is 18.4 to 19.6.


Bound on electro property

The WLTP range is also close to a stalemate. BMW offers for the moment only the i7 variant available with 590-625 kilometers. With the EQS 580 4Matic it is between 582 and 679 kilometers. However, the 580 is not the most energy-efficient EQS: the rear-wheel drive EQS 450+, whose usable battery capacity is also 107.8 kilowatt hours, has already proved in the hands of our car whisper. electric Alexander Bloch how easy it is to cover well over 600 kilometers with one battery charge to leave. With its 101.7 kilowatt-hours of high-voltage energy storage, the i7 should have more trouble in this exercise. At least until it is also available in fuel-optimized model versions.


Since there has been largely a draw so far, the question of which flagship has the best electrical properties must be decided by the charging time. In fact. Because even in this category, none of the upper-class models manages to stand out in a decisive way. The i7 pumps direct current into its battery with a maximum of 195 kilowatts, the EQS manages a maximum of 200 kW. The following always applies: It only works for a few minutes (probably more like seconds), because otherwise the temperature in the energy storage would rise too much and the battery cells would suffer. As a result, the charging time from 10 to 80 percent of the quick charger’s battery capacity is 34 minutes for the BMW and 31 minutes for the Mercedes. At the eleven kW charging station or wallbox, it takes nine and a half to ten hours to get from ten to one hundred percent.


4: 3 for BMW in the drive section

Does at least one of the competitors therefore have big nostrils or the shining star ahead in terms of engine data and driving performance? Definitely yes, but depending on the category, Munich or Stuttgart. The i7 xDrive60 offers the highest engine power (400 kW / 544 hp instead of 385/523 hp) and higher speeds in the left lane (top speed is electronically limited to 240 km / h; with the EQS 580 4Matic already at 210 km / h). On the other hand, the Mercedes offers significantly higher maximum torque (855 instead of 745 Newton meters) and accelerates from zero to a hundred much faster (4.3 instead of 6.1 seconds). So the score here is 2: 2.

The permanent magnet synchronous motors (PSM) of the BMW i7 do not need rare earths at all. The EQS doesn’t quite handle it.

Or 3: 3 if we consider that permanent excitation synchronous machines (PSM) are used in both cases. “The advantage of these engines is that they can run sparingly, especially when performance requirements are low,” explains electric car specialist Bloch. In the case of the i7, these are excited by the current and thus also do without the so-called rare earths, which improves the environmental balance of the model. Mercedes has at least minimized the expensive metals in its electric motors, some of which are mined under questionable conditions, but have not been able to eliminate them. But still 4: 3 for BMW in the recovery minutes of the drive chapter.


A lot of car, a lot of weight

Let’s face it: both the BMW i7 and the Mercedes EQS are colossal cars. The Bavarian is not only a little stockier than the Swabian in terms of appearance: he is longer (5.39 instead of 5.32 meters), taller (1.54 instead of 1.51 meters) and much heavier ( 2,715 instead of 2,585). ). Is the platform not just electric? It may be, but that doesn’t stop it from being clearly ahead when it comes to payload. If needed, the i7 can hold up to 535 kilograms, which increases the total permissible weight to a staggering 3,250 kilograms. Mercedes carries a maximum of 475 kilograms on board; makes a gross vehicle weight of 3,060 kilograms. The Mercedes is also behind in terms of towable load (750 kilograms instead of 2,000 braking). However, trailers may not be necessary for him at all, because he offers a larger trunk (610 instead of 500 liters). In addition, the trunk can be expanded up to 1,770 liters; The rear seats of the BMW cannot be folded down.

The BMW i7 is a very large and extremely heavy car. The permissible total weight is 3,250 kilograms.

At this point we could get lost in the infinite digital possibilities. But we just compare the obvious: the quantity and size of monitors. In this sense, the EQS is more forward-looking and puts the MBUX hyperscreen in the balance: three screens in the dashboard which, thanks to the joint coverage, appear as a particularly large monitor that extends over almost the entire width of the vehicle. In the front row, the i7 only features a rather small – in comparison – curved display. In return, it offers a cinematic feel to the rear, with a 31.3-inch 8K resolution screen that can be folded out of the roof lining.


The EQS should soon be able to achieve level 3 autonomy

Instead of highlighting the detailed differences in high-tech frames or delving into increasingly sophisticated security systems, we prefer to head to the fair and have a look at the crystal ball in person. Which quickly brings us to the subject of “autonomous driving”. Level 2 automated driving functions can currently be used in both models. Mercedes wants to bring the EQS to the level 3 standard in the first half of 2022. The “Drive Pilot” is the first combination of assistance systems in the world to have this type approval. BMW wants to follow “in the medium term”; the term does not suggest that this will happen in the very near future.

Mercedes-AMG EQS 53 4-Matic

Mercedes

The Mercedes-AMG EQS 53 4Matic + will arrive soon and already comes with a price.

And what about the next power models? The Mercedes-AMG EQS 53 4Matic + has been announced for this year and is already priced (152,546 euros). It arrives – at least after booking the “AMG Dynamic Plus” package, which costs 4,760 euros – at 560 kW / 761 hp, a maximum of 1,020 Newton meters and a top speed of 250 km / h and accelerates from zero to one hundred km / h in 3 , 4 seconds. Here, too, BMW takes a little longer; the M70 xDrive with “significantly more than 600 hp” and over 1,000 Nm will not arrive until 2023. If you look at the iX M60, which is closely related in terms of driving technology, the all-wheel drive vehicle should even deliver up to at 455 kW / 619 hp and a maximum of 1,100 Newton meters. No matter how much power exactly: BMW initially promises “only” an acceleration time from 0 to 100 km / h in less than four seconds. It seems that both of them are ahead here too. Which keeps things pretty exciting.

Conclusion

The BMW i7 xDrive60 and Mercedes EQS 580 4Matic are the best examples of how completely different approaches can lead to very similar results. Neither in electrical properties nor in performance values ​​or practical properties can one of the noble rivals obtain decisive advantages. If at all, it’s in the details: the i7 does without rare earths, the EQS will soon be able to drive autonomously at level 3. Comparing the data ultimately leads to a crucial discovery: we must push the old road. on the road and on the test site to find out which is the best electrically powered luxury cruise ship. And we will do it as soon as possible, you can be sure.
