Although the Mercedes-Benz EQS is already exhibiting the world simply how nice long-range electrical automobiles will be, it is nearly to interrupt the ice.
The firm’s true next-level EV innovation is ready to reach in 2024, and it got here out on Monday within the type of the Vision EQXX idea.
Whereas EQS Fastback And eQi sedan, and upcoming EQS SUV and EQE SUV, all to be constructed on its Electric Vehicle Architecture (EVA), the remainder of Mercedes-Benz’s compact and mid-sized fashions will likely be constructed on a set of bases referred to as Mercedes-Benz Modular Architecture (MMA) coming later within the decade. ) – Previewed in EQXX.
EQXX, which builds on Vision IAA Concept From the 2015 Frankfurt Auto Show, the unique definition of the phrase reveals all of the indicators of being a geeky hypercar challenge. like Volkswagen XL1, it’s gentle and lean and goals for effectivity at each determination level.
Mercedes Vision EQXX EV Concept
With a battery pack of lower than 100 kWh, Mercedes claims it may possibly obtain a real-world vary of greater than 1,000 km (about 621 mi) – us VW’s 1-litre-per-100-km vary with the XL1 Reminds me of a goal. ,
And but the 2 tasks could not be extra completely different with regard to manufacturing goals. In a collection of Q&A periods held on Monday after the reveal, Mercedes-Benz executives defined that the EQXX will not be as far off because it seems.
“Every element we see in this car will make it into series production,” stated Marcus Schaefer, chief expertise officer at Daimler AG and a member of the Mercedes-Benz board of administration.
Along with Schaefer and Daimler AG’s chief design officer from that point, Gordon Wagner, we received some first impressions of how deep these components are coming collectively. The automaker could have a really enticing and aggressive set of luxurious EVs by the center of the last decade. Here are a collection of technical factors about how the EQXX idea alerts what’s to come back:
Mercedes Vision EQXX EV Concept
Lightness is essential. The EQXX is constructed on a 110.2-inch wheelbase, and is formed like a Mercedes-Benz C-Class or Tesla Model 3, Overall curb weight is 3,850 kilos, which if carried over to the manufacturing mannequin will considerably cut back the Model 3’s curb weight whereas providing extra battery and vary.
An enormous increase within the vary. Mercedes is able to make a press release with the EQXX’s declare of 621 miles. “We think range will matter to our customers for a long time,” Schaefer stated. “We are talking about the real life range; that means the certified range is more than 1000 km in this location.” The firm now has the toolbox to ship 1,000 km. But if it would not, Schaefer defined, it may cut back it — chopping prices, simpler supply-chain burdens, and decreasing weight.
Mercedes EQXX Concept Energy Density
Rethinking the battery. Mercedes says that in comparison with the battery pack within the EQS, it is half the dimensions and 30% lighter, whereas permitting for roughly the identical quantity of power. The cells used within the EQXX would come with a “very strict” cell-to-pack battery format that was influenced by expertise gained in F1 racing. The cells alone present a 20% enhance in power density over these utilized in EQS, Schaefer stated, earlier than permitting for the density benefit of the pack design.
Electric propulsion within the house. This marks the debut of the primary E-Drive system designed completely by Mercedes, which consists of the battery, E-motor and software program. Schaefer underlined that it is working on check benches proper now and with small-scale permission from regulators, will likely be examined on real-world roads inside a couple of months at EQXX.
Help from F1 Racing. Schaefer stated it took its e-drive improvement again in-house as a result of its engineers had a number of concepts for taking motor effectivity to the subsequent stage. Once it tackled this, it aimed to revamp the inverter taken from Formula One racing, incorporating silicon carbide expertise. It additionally introduced software program and software program improvement in-house. The outcome, it claims, is an astonishing 95% battery-to-tire effectivity.
Mercedes EQXX Concept Efficiency
Multiple battery chemistry, modular motor system. Mercedes plans to supply a spread of battery chemistries relying on the wants and value of the vary, in addition to completely different energy outputs that may usher in as much as 500 kW (671 hp). And earlier than seeing what AMG provides to this scalable, modular system, Schaefer indicated.
All-wheel drive is on the market, however rear-wheel drive is on the high of the effectivity scale. Using the house below the hood for different functions, Schaefer stated, the one-motor idea makes probably the most sense to permit for the bottom power consumption.
Cast physique with sell-to-pack. Mercedes will start a BionEQXX casting course of that shapes the rear construction of the automobile right into a single casting, which incorporates the battery housing inside the subframe of the forged construction. Schaefer assured us that the method is sure for chain manufacturing.
Mercedes EQXX Concept Battery
Back to air-cooled batteries? With MMA automobiles Mercedes is more likely to transfer away from liquid battery-pack cooling in favor of a “passive,” air-cooled method. The technique will embody clever cell administration all through the pack, in addition to an built-in cooling plate on the underside, mixed with vents that open as temperatures climb, defined Schaefer, who referred to as it “the battery’s natural cooling.” Again, he defined, the goal is to save lots of power, as a result of pumping fluid by means of a system would price extra power.
Fast charging—with a couple of methods to come back. Initially with this technique Schaefer stated the automobiles would have the ability to get well a distance of about 300 km (186 mi) in quarter-hour—not as quick as packed in EQS, however not too gradual. “With a system like this, the number one priority for us is range,” Schaefer stated, hinting that there will likely be extra information associated to the MMA platform and even quicker charging.
Mercedes EQXX Concept Aero
More lively aero. The EQXX has an distinctive coefficient of drag of 0.17. We’ve seen loads of fashions with lively grille shutters, however count on a brand new stage of lively aerodynamics when the MMA fashions arrive in 2024 and 2025.
Mercedes EQXX Concept Solar Roof
a photo voltaic roof. According to Schaefer, the corporate plans to put in photo voltaic roofs on its manufacturing automobiles beginning in 2024. “Solar roofing will be a very important element of the future,” he stated, predicting a time when clients can have a alternative between a glass roof. —as supplied on the EQS, maybe—and a photo voltaic roof. Mercedes indicated {that a} photo voltaic roof within the EQXX may present as much as 25 km (16 mi) of restoration per day. It’s a really completely different determination than Toyota and Hyundai, which not too long ago determined to not carry photo voltaic roofs to US clients. bZ4X And Ionic 5, respectively.
Mercedes Vision EQXX EV Concept
Long tyres. “We were able to come up with a new concept here, with new partners for the next generation of tyres,” Schaefer stated. With the targets of low rolling resistance however good dealing with efficiency, Mercedes helps drive that development. Wagner famous that the challenge arrived at a bigger, taller tire with the automobile’s rear monitor truly barely narrower than the entrance monitor, so they might move by means of the wind channel.
Mercedes Vision EQXX EV Concept
Hyperscreen Horizon. Mercedes takes some concepts from the hyperscreen interface that simply launched within the EQS and goes horizontal right here, with a totally seamless display spanning 47.5 inches from one entrance pillar to the opposite. Wagner calls this a “high-tech luxury approach”, evaluating it to older Bang & Olufsen designs. A sport engine helps create a wholly new fluid person expertise that’s as immersive—or as easy—because the person.
