When converted to electricity, the three-compartment sedan became obsolete: here’s why

– EV Updates 2022

Not everyone who loves an electric vehicle likes an SUV. Longer and shorter electric cars have more durability — especially optimized to increase the driving range on highway models.

But they are less than you might think, traditional three-box sedans with a hood, a cabin and a trunk. And most of them have “compact” rooflines and hatchbacks.

Simply put, if you design a car around low aerodynamic traction, it will exceed the battery power that saves more than a kilowatt-hour of highway miles — that is, the car has a lower cost and less environmental trajectory. The sedan shape causes turbulence behind the rear window.

This is especially important for entry-level luxury models where all the numbers have to stand alone against the basic passenger devices, yet to be kept at the price point. That’s why, with the Mercedes-Benz Vision EQXX launching in 2024 on the MMA platform, a preview of a generation of smaller EVs, Mercedes went fully with the Aero.

The EQX Concept achieves an excellent 0.17 traction coefficient — far below current production four doors. Company officials pointed to its aerodynamics as one of the keys to its real-world range of 621 miles on a battery pack of less than 100 kwh, perhaps with air cooling to the battery.

It is no mistake that many aerodynamic vehicle designs have moved towards the same teardrop shape and comeback roofline. The Toyota Prius adopted it in 2004, and it helped the nameplate rise to mpg and became an iconic design. A decade ago the Volkswagen XL1 was VW’s “1-liter car” – a vehicle designed to chase 100 km on a liter of diesel, or 235 mpg. The Netherlands’ LightEar claims that its One Electric car, with a CD of less than 0.20, is the most aerodynamic car in the world. Even the Aptera, a three-wheeler, follows the same teardrop shape that allows for a range of up to 1,000 miles.

You could say that the Kia Stinger and Audi A7 family are also part of the Compaq family. Both have a hatch and more rear overhang than most modern sports-sedan designs.

At EQXX, the teardrop look, with a long roof, extension behind the rear wheels and a high, disconnected rear end aims to integrate some of these ideas — but with practicality it will effectively push the performance of a sedan. In the future interested in a new aero.

According to Stephen Lammin, head of advanced design at Mercedes-Benz AG, four people must fit the concept and it must be “realistic” and “mature”. It posed a special kind of challenge against making an ultra-aero concept.

The larger 2022 Mercedes EQS, a ragged hatchback, has already struck a staggering 0.20 traction coefficient, but the lesser cars in anticipation (180 inches longer than the EQXX) remain a major challenge in the airway.

That is, the traction coefficient of EQXX at 0.17 includes some compromises between practical and attractive design, and chases the final air-tunnel results. According to Teddy Wall, head of Mercedes Aerodynamics, the purchase is part of a buy-in design that does not include wheelspaces — the flush covers found on the XL1, EV1 and the original Honda Insight. The wheelwheel’s wheels near the opening and the smooth rim design “helped to provide almost the same effect as the Spades,” Wall said. He agreed that adding spots would not have significantly reduced the traction coefficient.

There is a simple reason for that, Wall explained Green Car Reports. Adding spots will require even more “boat tailing” (tapping).

The slight narrowing at the back allowed for most of the benefits, Wall said. IDXX rides in the rear lane, which is almost two inches shorter than the front (1850mm, 1900mm)

While we doubt that high, lean tires — the potential for further growth — and narrower tracks in the rear will lead to production, it makes sense for some pieces to follow suit. The sharp corners at the rear provide aerodynamic benefits to the EQXX, experts say, similar to the lower roof on the rear occupants. To help compensate, future vehicles will not offer space-consuming solar roofs, instead of having to choose between a solar roof or a glass roof.

Future cars may have a long rear window and a narrow declit (trunklit) or they may be hatchbacks. After all, they are not the same sedans or sport sedans that helped build Mercedes, BMW and other luxury-brand leaders in previous decades. SUVs make definite compromises in the name of form and capability, but from its sound, this is the profile of cars we have to accept for the future.
