Mercedes bets solar paint is part of EV-charging future

It’s been said that Albert Einstein’s genius came from his ability to freely wonder and ask child-like questions way before he even tried applying science-based solutions.

It seems some within the R&D department at Mercedes-Benz might be similarly inspired. The German automaker is currently developing a special solar paint that, when applied on the surface of vehicles, can harness enough energy from the sun to power up EVs.

The energy generated by the paint’s solar cells can be used for driving or fed directly into a high-voltage battery.

“The photovoltaic system is permanently active and also generates energy when the vehicle is switched off,” Mercedes says. “In the future, this could be a highly effective solution for increased electric range and fewer charging stops.”

The layer of paste to be applied on EVs is significantly thinner than a human hair, yet its photovoltaic cells are packed full of energy. Covering the surface of a mid-size SUV with the paint could produce enough energy for up to 7,456 miles per year under ideal conditions, Mercedes says.

This does imply being in geographic locations with plenty of sun hours during the day.

But even with less-than-ideal sun hours, the energy yielded can make a significant difference to EV charging. Mercedes says the solar-paint charge could provide 100% of needed energy for an average daily drive of 32 miles in sun-drenched Los Angeles. In much less sunny conditions — such as around Mercedes’ headquarters in Stuttgart, Germany — it would still yield enough energy for 62% of the distance.

An added bonus for environmentally-conscious drivers: Unlike some solar panels, the solar paint contains no rare earth or silicon – only non-toxic, readily available raw materials. It’s also easy to recycle and considerably cheaper to produce than conventional solar modules, Mercedes says.

The likes of Aptera, Sono Motors, Lightyear, and Hyundai have also been researching how to best harness solar energy to power up EVs.

But that’s been mostly through solar panels yielding enough energy for small and light vehicles, such as Aptera’s three-wheel solar EV. Solar paint could bring solar charging for bigger vehicles, such as electric SUVs, Mercedes says.

We need more 7-passenger EVs, but the 2023 Mercedes EQS SUV has room to improve

Front three quarter view of the 2023 Mercedes-Benz EQS SUV.

Mercedes-Benz is continuing to expand its EV lineup, this time with a model aimed at (wealthy) families.
As the name states, the 2023 Mercedes-Benz EQS SUV is an SUV derivative of the EQS sedan. With the EQS sedan positioned as the electric analog to the Mercedes S-Class, the EQS SUV is the electric version of the GLS-Class. And like that vehicle, the EQS SUV is available with up to seven seats across three rows.
That makes the EQS SUV an important vehicle not just for Mercedes, but for the cause of EV adoption in general. While the Tesla Model X and Rivian R1S also offer three rows for family-hauling duty, there’s a lot more room in the market for another entry. Given the popularity of equivalent gasoline luxury SUVs like the GLS, Land Rover Range Rover, and Cadillac Escalade, the EQS SUV arrives not a moment too soon.
The EQS SUV is scheduled to reach U.S. dealerships this fall in three guises. The base rear-wheel-drive EQS 450+ starts at $105,550 with destination, while the all-wheel drive EQS 450 4Matic and EQS 580 4Matic start at $108,550 and $127,100, respectively. Although it will be built in Alabama, the EQS SUV won’t qualify for the revised federal EV tax credit because it exceeds the $80,000 price cap for SUVs.

Design and interior
A defining feature of Mercedes’ EQ lineup is aerodynamic bodywork aimed at maximizing range. The typical SUV is not aerodynamically ideal, but Mercedes managed to achieve an impressively low drag coefficient for an SUV — at 0.26, it’s close to the Toyota Prius. But function clearly took precedence over form. Mercedes deserves credit for not going in the polarizing direction BMW did with its two-row iX SUV, but the EQS SUV looks like a melting scoop of ice cream.
More disappointing is the third row, which should be the EQS SUV’s defining feature, but seems more like a useless afterthought. Adults will find it difficult to insert themselves into the third-row seats, let alone tolerate riding in them. As in most three-row vehicles, the rear seats also pretty much eliminate cargo space. And if you want to fold them down to create more cargo room, you’ll have to do it manually as Mercedes didn’t include a power-folding system — a bit disappointing for a six-figure car. The EQS SUV also lacks a frunk; like the EQS sedan, the hood is sealed.

Lux and refreshingly livable, Mercedes’ EQE moves EVs mainstream

Front three quarter view of the 2023 Mercedes-Benz EQE sedan.

Mercedes-Benz wants its EQ sub-brand to be an all-electric counterpart to its current lineup of gasoline luxury cars, and it’s working toward that goal by starting at opposite ends of the price spectrum and working toward the middle.
Where the EQS sedan and SUV are the flagships of the lineup, and the EQB serves as an entry-level offering, the 2023 Mercedes-Benz EQE sedan aims for the middle of the market. It’s pitched as an electric equivalent of the Mercedes E-Class, one of the automaker’s bread-and-butter models. And like the E-Class, the EQE will compete against sedans from Mercedes’ German rivals, such as the Audi e-tron GT, BMW i4, and Porsche Taycan. It will likely be cross-shopped against the Genesis Electrified G80, Lucid Air, and Tesla Model S as well.
The EQE sedan arrives at U.S. dealerships in late 2022 in four guises: base rear-wheel drive EQE 350+, all-wheel drive EQE 350 4Matic and EQE 500 4Matic, and an AMG EQE performance version. Mercedes hasn’t disclosed pricing for any of these models, but the EQE 350 4Matic we tested for this first drive will likely be a mid-tier trim level. Like its EQS sibling, the EQE will also get an SUV variant, which will launch sometime after the sedan version.

Design and interior
The EQE has the same lozenge-like shape as the EQS sedan, which is dictated by aerodynamics. The appeal of the design is up for debate, but the smooth shape reduces aerodynamic drag, which helps improve efficiency and range. Under the skin, the EQE is also based on the same EVA2 architecture as the EQS sedan.
But while the two EQ sedans look similar at first glance, the EQE is a bit smaller than its sibling. It’s 10.6 inches shorter than the EQS sedan, with a 3.5-inch shorter wheelbase. Rear-seat passengers might notice the difference, but like its gasoline E-Class counterpart, the EQE is aimed more at drivers than passengers. Its tidier proportions were also a bit more pleasing to our eyes, making the EQE look sleeker than its sibling.
The interior design is minimalist while still maintaining functionality.

We drove Mercedes’ hand-built EQXX concept, and it’s unlike any other EV

Front view of the Mercedes-Benz Vision EQXX.

It may have the familiar three-pointed star on its hood, but the Mercedes-Benz Vision EQXX is like no other car Mercedes — or any other automaker — has ever built.

The Vision EQXX is an electric concept car that debuted at CES 2022 earlier this year. But where many concept cars can’t even move under their own power, the Vision EQXX spent the months after its Las Vegas reveal setting range records with a pair of epic trans-European road trips. Because while most concepts focus solely on design, the Vision EQXX pushes the envelope in all areas, from the shape of its body to the code in its software.
