How Mercedes-AMG’s Project One will influence car design

Mercedes-AMG is taking baby steps into the world of electrification. It’s the proverbial calm before the storm. In Detroit this year, the company introduced a line of mid-range models denoted by the -53 suffix that rely on a mild hybrid system to boost performance while keeping fuel economy in check. They represent the first salvo in a model blitz that will include a plug-in hybrid powertrain with V12-like power and culminate with the mind-bogglingly quick Project One.

“We have a lot of other opportunities,” Mercedes-AMG boss Tobias Moers told Digital Trends when asked about the future of the V12 engine. “Electrified powertrains,” he clarified.

Electrifying a performance car presents a unique set of challenges. The extra hardware inevitably adds weight, which in turn compromises handling and performance. Moers explained it takes engineering prowess to overcome these obstacles. “It works perfectly if you do it the right way,” he suggested before providing us with an example.

“You can expect some technologies transferred from Project One to our other cars.”

“Maybe you remember the GT concept from Geneva last year. It had a V8 engine in the front and an electric motor on the rear axle. Everything is in development. It will go into production one day,” Moers revealed. That’s good news for performance enthusiasts.

Shown to preview the GT Four-Door Coupe, the concept allied an evolution of AMG’s twin-turbocharged, 4.0-liter V8 engine and a powerful electric motor to offer a monstrously high output of 805 horsepower. It took less than three seconds to reach 60 mph from a stop. Alternatively, the battery pack stored enough electricity to power the sedan on its own for short distances.

Will those specs carry over? “More or less, yeah.” AMG will develop its own battery pack in order to reign in weight gain. It could also rely on carbon fiber to shed extra pounds in standalone cars like the two-door GT. Adding composite materials to a model based on a Mercedes-Benz platform (such as the E-Class or the GLC) becomes more complicated, though.

Moers believes noise represents a big part of AMG’s emotional appeal. He’s not interested in making a quiet car that doesn’t rumble a little bit when its features get ruffled because the passengers won’t feel the power and the performance stuffed under the hood. Every car in AMG’s current portfolio snaps, crackles, and pops as it races around a track. At full song, the GT sounds like Germany’s answer to Pavarotti. So, what happens when you turn off the combustion engine and drive only on electricity?

“If you run [12 miles] in electric mode, then maybe it’s okay to have your freedom and it’s quiet. We’re not fully done with it, though. We do a lot of research together with companies, musicians, gaming people to find what could be the right sound for an electric-driven AMG. We’re not done with that journey; we’re just collecting a lot of input.”

AMG will release another form of mild electrification: electric turbocharging.

He also told us AMG will release another form of mild electrification: electric turbocharging. Already found in a small handful of production cars, including the Audi SQ 7, the electric compressor delivers a boost without a hint of lag because it’s zapped into action. In comparison, a standard turbocharger driven by exhaust gasses needs time to spool up. Moers wouldn’t reveal precisely when we’ll see AMG’s electric turbo in showrooms but he assured us it’s not a long-term project that’s a decade out.

Electric turbocharging technology comes straight from the Project One, the Formula-One-turned-road-car AMG unleashed last year as a birthday present to itself. It’s a hybrid, too. Its 1,000-horsepower powertrain consists of a V6 borrowed from the brand’s championship-winning Formula One car, a pair of electric motors that power the front wheels, and a third motor for the rear wheels.

The entire 275-strong production run is already sold out in spite of a $2.7-million price tag. Moers never expected such an immensely positive response to the Project One; AMG could quadruple production and still sell every example. More than a future classic, it’s a rolling showcase of the brand’s engineering might, and it will have a formative influence on future production cars.

“You can expect some technologies transferred from Project One to our other cars,” Moers revealed. “We are chasing performance with hybrids, not long range. We could do that, but our first approach is a performance approach,” he added.

2023 Mercedes-Benz EQE SUV preview: The EV lineup grows again
Front three quarter view of the 2023 Mercedes-Benz EQE SUV.

As Mercedes-Benz has steadily expanded its EQ range of electric cars, the lineup has become a bit like the late stages of a Tetris game. It’s mostly complete, but with a few gaps still left. And the 2023 Mercedes-Benz EQE SUV is the piece that perfectly fits one of them.
Mercedes recently launched two other electric SUVs at opposite ends of the price spectrum. The EQS SUV is positioned as the lineup’s flagship, while the EQB is the entry-level model. The EQE SUV slots between those two in size and, presumably, price. The latter hasn’t been confirmed yet, and likely won’t be until the EQE SUV’s planned March 2023 on-sale date.

As the name says, the EQE SUV is a utility-vehicle version of the EQE sedan, which will likely beat it to showrooms by a few months. Mercedes did the same thing with the EQS, which is available in both SUV and sedan body styles.
With its tall, upright profile, the EQE SUV definitely looks like a proper SUV compared to the low-slung EQE sedan. Park it next to an EQS SUV, though, and you’ll have to get out a measuring tape to spot the differences.
The EQE SUV is 0.6 inch narrower and 1.2 inches lower than the EQS SUV, but the most significant difference is in length. The EQE SUV is 10.3 inches shorter than the EQS SUV, with a 2.1-inch shorter wheelbase. And while the EQS SUV has three-row seating, the EQE SUV has two rows. Based on our experience with the EQS SUV’s third row, that’s not a big loss.
The interior design theme carries over from other Mercedes EQ models, with an expansive sloping dashboard designed to accommodate many screens, and multicolor ambient lighting that should look pretty dramatic at night. However, leatherette upholstery is standard, rather than real leather, which Mercedes is now spinning as a vegan option.

We tested the self-driving Mercedes tech so advanced, it’s not allowed in the U.S.
Mercedes-Benz S-Class sedan with Drive Pilot.

You can’t buy a fully self-driving car today -- and may never be able to -- but automakers are looking at ways to shift more of the workload from human drivers to machinery. Mercedes-Benz may have taken the biggest step in that direction yet.

Mercedes claims its Drive Pilot system, which was recently launched in Germany, is the first production system to achieve Level 3 on the Society of Automotive Engineers (SAE) autonomy scale, meaning the car can fully drive itself with the system active, but a human driver may still need to take over from time to time. It’s still a long way off from autonomous driving, but the Level 3 designation signifies a greater degree of capability than competitor systems.

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.
