Every new generation of Mercedes S-Class has set a standard, not just for other Mercedes, but for all cars. From style, luxury and (most importantly) technology, the S-Class has constantly been the benchmark other automakers aspired to surpass.

The latest iteration of the full-size luxury sedan endeavors to do the same, but in an era when even a $16,000 Chevy Spark comes with a 7-inch color touchscreen, how does the S-Class maintain its paragon status? Simple – Pack it with more gadgets, features, and details than ever before.

Mercedes-Benz’s S550 4Matic packs a 4.6-liter Bi-turbo V8 under the hood, sending 449 horsepower and 516 pound-feet of torque to all four wheels by way of a seven-speed automatic transmission.

Motorcade mainstay

The silhouette of the S-Class is unmistakable across the globe, and the S550 carries on the tradition of maintaining that presence, modernizing the car with minor tweaks, like a larger grille and flowing shape. Take the term “full-size” sedan to heart: There’s a lot of car here. Having one on hand, I didn’t know if I was coming off as a dignitary, professional businessman, or an Uber Platinum driver. But I did know that I had a wealth of technology to satisfy any situation.

That starts with the lighting: There isn’t a single light bulb to be found on the exterior or the interior. Fifty-six LEDs illuminate the road ahead while 35 LEDs make up the tail lights. Throughout the inside, there are nearly 300 of them performing various tasks including setting the mood with the ambient lighting package.

Behind the steering wheel sit two 12.3-inch high-resolution TFT screens where much of the techno-magic happens. One replaces traditional analogue gauges with a fully digital set that also communicates radio, navigation and phone info while it’s in use.

The neatest trick this screen has up its sleeve is the Autoliv night-vision system that brings an extra element of awareness to the car. The night vision displays itself between the gauges, near to the driver’s eye line. This display gives an enhanced black-and-white view of the area in front of the car and is also able to identify pedestrians at low speeds. I was stunned how the Autoliv system was able to spot pedestrians on the sidewalks of roads and highlight them in a red box before I was able to see them through the windshield.

Centered in the dash is the screen for the Mercedes COMAND system. The touchpad in the center console, drivers can flip through the menus that are displayed in an elegant user interface. Some modes show a diagram of the S550 on screen, highlighting selected systems like the engine or suspensions as you configure them

There’s a menu to adjust everything, from the different available massages afforded by the front seats to the level of potency of the fragrance the climate control has built into it. Once my phone was paired, I was even able to access the Internet through a built-in Web browser, though it seemed to be there just to show that it can be done. Web surfing from my phone without the Mercedes middle man was a far faster and more useful experience.

Would this be a Mercedes without a boatload of electronics? Certainly. Take away every little modern feature and this would still be an exquisitely crafted luxury automobile. The cabin is replete with supple Nappa leather surfaces accented by wood trim, contrasted by aluminum touch points in all the spaces in-between.

Power with poise

Powering the nearly 5,000-pound car is a 4.6-liter Bi-turbo V8 that dispenses 449 horsepower and 516 pound-feet of torque, hefting it from 0 to 60 in 4.8 seconds. That is more than enough to make a spirited jaunt to and from destinations. Mercedes’ 4MATIC all-wheel drive system keeps things firmly planted on just about any road condition thrown at it, while the seven-speed transmission routes power either with comfort and efficiency in mind or dynamic performance.

Woven into the S550 are a host of other sensors and functions designed to keep occupants (and pedestrians) as safe as possible.

Opting for the 4Matic system foregoes the automaker’s Magic Body Control, which isn’t a sexy dance routine, but an adaptive damping and suspension system that adjusts to match the approaching road surface. Stereo cameras scan the road ahead to detect uneven terrain, instantaneously communicating that to the on-board computer which optimizes the suspension automatically.

Woven into the S550 are a host of other sensors and functions designed to keep occupants (and pedestrians) as safe as possible. With functions like Pre-safe Plus, the car can detect pedestrians at low speeds and brake autonomously if one is suddenly in the car’s path. The same goes for when the Mercedes detects an imminent rear-end collision, which not only brakes, but does so in a controlled manner to reduce whiplash, as well as controlling seat belt tension as to reduce injury.


Having to meet the expectation as the car with the most built-in toys in today’s tech-heavy world, it seems the idea of “too much” probably never occurred to Mercedes. To be fair, it probably doesn’t occur to any other luxury automakers either, but for the S550, it seems like there’s so much going on to the point of distraction. As beautiful and eye-caching as the interface is for the COMAND system, it’s just that: eye catching. Manipulating functions on the myriad of settings menus means more time looking at the gorgeous graphics and not at the road. A few functions can be done with a blind button push, but they are few and far in-between.


Being the showcase for the brand means that all these gizmos appear across the lineup, too. For all the useful safety and comfort features that proliferate across the brand, the other Mercedes vehicles are picking up the S-Class’s bad habits as well. Mercifully, we are talking about a carmaker that has been in the game long enough to lock down the fundamentals of quality vehicle engineering and know that gadgets do not a good car make. The things that make the S-Class great are the things that came before sensors and night vision – comfort, performance, and a quality build with top materials.


In comparison to rivals like the Audi A8, the Mercedes S550 seems more fanciful, whereas the Audi is all business. That level of luxury comes with a substantial price tag as well. Starting at $97,400, the S550 already begins at a cost nearly $8,000 higher than its Audi contemporary. Yet the A8 has many similar technology features, and significantly more user-friendly methods to use them.

The Mercedes-Benz S550 is still the vehicle that automakers will try to emulate, but none will be able to match the distinct S-Class experience. The car’s near overreliance on tech novelty, however, overshadows the fundamentally well-crafted platform it’s built upon. Less is more, but when “less” is off the table, the “more” needs to feel less overwhelming.

Tesla Model X vs. Tesla Model Y: Range, speed, price, and other specs compared
Novitec Tesla Model X

Every major carmaker, from Ford to Volvo and beyond, makes an EV these days, but Tesla has had a bit of a head start. As a result, it now offers a well-rounded lineup of electric cars, including sedans and SUVs. Tesla’s cars are still some of the best EVs out there, and if you’re in the market for an electric car, you’re likely considering a Tesla.

Larger cars, like SUVs and crossovers, are the most popular in the U.S. right now — and Tesla offers two of them: The Tesla Model X and the Tesla Model Y. Both have their advantages and disadvantages, and there are a few major differences, including price. Here’s everything you need to know about the two cars and why one or the other might be better for your needs.

Chrysler Synthesis demonstrator brings more screens and software to vehicle cockpits
Chrysler Synthesis cockpit demonstrator

Chrysler isn’t generally known for technological innovation, but the brand at the core of automotive conglomerate Stellantis wants to change that.
Unveiled at CES 2023, the Chrysler Synthesis demonstrator is a mock-up of what the automaker claims is its vehicle cockpit of the future. Featuring a vast expanse of screens and smart software, it sets expectations as Chrysler prepares to revamp its aging lineup in the coming years with a fleet of EVs.

The two-seat cockpit demonstrator is dominated by two dashboard screens. One reaches nearly across the dashboard, while a second smaller screen is nestled into the passenger’s side corner of the dash. While front-passenger screens are already available on vehicles like the Jeep Grand Cherokee, from Chrysler’s fellow Stellantis brand, this is a more stylish application that makes it seem like the entire dashboard is one big screen, measuring 37.2 inches.
Behind the screens are three software platforms: STLA Smart Cockpit, STLA Brain, and STLA AutoDrive. STLA Smart Cockpit handles the displays, while STLA Brain enables underlying features like over-the-air (OTA) updates and a virtual assistant that can sync the car with a driver’s phone or smart home devices, as well as recommend parking and EV charging options or handle e-commerce transactions.
STLA AutoDrive is a driver-assist system that will allow drivers to take their hands off the wheel and their eyes off the road in certain situations, Chrysler claims. When engaged, the Synthesis cockpit reconfigures to let drivers do other tasks — such as videoconferencing or karaoke — that wouldn’t be advisable without a high level of automation.
Before setting out, the car welcomes its driver using biometric authentication, and can then set up a trip plan based on personal schedules, weather, and the car’s state of charge.
The physical cockpit demonstrator is based on the Chrysler Airflow concept, an electric SUV unveiled at CES 2022. Chrysler claims it was made with 100% sustainable materials, with all plastics derived from post-industrial sources or recovered from oceans.
This high-tech cockpit doesn’t correspond to a specific production car, however. The Airflow is still just a concept vehicle, and Chrysler was vague on how close the Synthesis layout is to being production-ready. Chrysler will be the first Stellantis brand to use the STLA Smart Cockpit, STLA Brain, and STLA AutoDrive tech platforms in North America, but they might appear in a different wrapper than what we’re seeing here. Chrysler has a habit of making bug CES announcements that don’t lead anywhere, going back to 2017’s Portal concept.
Chrysler plans to launch its first EV in 2025 and go all-electric in 2028. That’s not a difficult task considering that, with the imminent discontinuation of the 300 sedan, the only Chryslers left will be the Pacifica and fleet-only Voyager minivans.

VW previews its next electric car in trippy camouflaged form
Front three quarter view of a camouflaged Volkswagen ID.7 prototype.

The Volkswagen ID.7 is VW's next electric car, and while it won't be fully revealed until later in the year, the automaker provided a sneak peek at CES 2023.

VW said the production ID.7, which will be revealed in the second quarter of this year, will be influenced by the ID.Aero concept first shown in China in 2022. The camouflaged prototype VW brought to CES has the same general shape as the ID.Aero. It's a streamlined sedan that VW claims will have up to 435 miles of range as measured on the somewhat lenient European WLTP testing cycle.
