Next-gen 2023 Mercedes GLC: Everything we know in June 2022 [Update]

Update: ‘Next-gen Mercedes GLC Coupe’ section updated.

The all-new 2023 Mercedes GLC celebrated its world premiere on June 1, 2022. In this story, we take a look at what we know about the crossover-SUV sibling of the new C-Class which will likely arrive in the U.S. in fall 2022.

2023 Mercedes GLC design & features

On the design front, while the first-gen GLC is drastically different from the GLK, the second-gen GLC is more of an evolutionary departure. That said, all the body panels are new, and it has a longer wheelbase and lower stance for clear differentiation from the Mercedes GLB. We’ve talked more about dimensions in more detail in the next section.

The next-gen Mercedes GLC has sleek production headlamps that are more angular. They slant upwards like on the Mercedes EQS but aren’t as narrow at the outer ends. They connect to the radiator grille through a DRL strip at the upper edge, emphasizing the SUV’s width. The new radiator grille includes a chrome surround and a sporty louver in matt gray with chrome trim.

When viewed from the sides, the 2023 GLC looks barely any different from the previous generation. The rising beltline does lend it a slightly sportier styling. Plus, for the first time ever on a GLC, body-colored wheel arch liners are available with AMG Line for the first time (optionally along with staggered tires).

Instead of the stem mirrors like the first-gen model, the second-gen model features beltline mirrors. This makes the SUV more aerodynamically efficient and reduces the wind noise inside the cabin. The shoulder area has more definition and the character line is clearly visible. Multiple new alloy wheel designs will be available, in diameters ranging from 18 to 20 inches.

At the rear, the 2023 GLC has a sleeker appearance with slimmer, two-part tail lamps reminiscent of the C-Class.

The interior of the GLC has noticeably improved and looks much more upmarket. It features a new dashboard with a wing-like profile, new, flattened round AC vents inspired by the engine nacelles of an aircraft, and an elegantly floating center console. There is a greater sense of minimalism and opulence in the cabin. The optional panoramic sunroof is an improved one. The occupants can get an almost uninterrupted view of the sky because the lined cross-strut is slimmer than in the first-gen model.

Digital Light & second-gen MBUX

A main exterior feature of the 2023 GLC is Digital Light headlamps with projection functions. These headlamps should have three extremely powerful LEDs each. 1.3 million micro-mirrors refract and direct the light in each Digital Light headlamp, and thus, the total resolution is more than 2.6 million pixels. These headlamps are a premium option over standard LED headlamps. Customers specifying will get an additional option of projection functions that casts guidelines or warning symbols of the road ahead.

The new GLC features the second-gen MBUX with a fingerprint scanner and a more interactive voice assistant activated by the command “Hey Mercedes.” MBUX Smart Home function is also included in the new-generation MBUX, allowing the driver to keep a check on and control smart home devices installed at the residence.

A 12.3-inch fully digital instrument cluster and an 11.9-inch portrait display are standard in the 2023 GLC. The portrait orientation of the central display makes operating the infotainment functions easier. The all-new MBUX includes a special Off-Road mode to make the required changes to the vehicle more quickly and in a simpler manner.

Head-up display

A color head-up display is optional in the 2023 GLC. It projects information over an area measuring 9 x 3 inches 10 feet in front of the hood. The visual experience is similar to viewing on a 25-inch monitor. The HUD’s display module has a native resolution of 720 x 240 pixels.

OTA updates

MBUX supports over-the-air (OTA) updates, which means customers can install the latest software in it without any hassle. The download and installation take place in the background, and then the user has to agree for activating the update. Customers can activate new features anytime even after they have taken the delivery.

Transparent hood

When the driver activates the off-road mode, the central display provides a virtual view under the front of the vehicle. The driver can see the front wheels and their steering position on the touchscreen. Images from the 360-degree camera give the view under the vehicle at speeds up to 5 mph and then from 5-12 mph the view ahead.

Air-Balance (TBC for the USA)

Several improvements that take care of occupants’ well-being are also part of the interior changes in the 2023 GLC. This aspect includes the availability of features like Air-Balance Package that provides the preferred fragrance in the cabin for a refreshed feeling.

Energizing Coach (TBC for the USA)

Energizing Coach gives individual fitness recommendations based on an intelligent algorithm, and it can work in sync with wearables. It suggests a suitable fitness or wellness program based on the vehicle and trip data and the information about sleep quality and stress level from a paired wearable device like a smartwatch. The plug-in hybrid variants benefit from an additional “Power Nap” program, with falling asleep, sleeping, and waking phases that can help the driver recharge himself/herself when making a stop for service or battery recharge.

Rear-axle steering

For the first time, customers will be able to order the Mercedes GLC with rear-axle steering (with an angle of 4.5 degrees), an optional feature that reduces the turning circle by 80 cm to 11.0 meters. The driver needs fewer turns of the steering wheel for a full lock when performing a U-turn or parking. At 60 km/h (37 mph) or higher speeds, the rear-axle steering steers the wheels in the same direction as the front wheels, leading to improved handling stability and safety.

Airmatic air suspension (TBC for the USA)

The Airmatic air suspension is standard in the plug-in hybrid variants, which we expect to be loaded to the brim. However, these electrified variants could suffer from the typical drawback of lower cargo space because of the battery pack location.

In the mild-hybrid variants, Mercedes-Benz offers the Airmatic air suspension as an optional feature. As standard, the 2023 GLC gets a new four-link suspension at the front and a multi-link independent suspension at the rear.

Traffic Sign Assist

Traffic Sign Assist detects conventionally signposted speed limits as well as signs on overhead gantries and in roadworks. Conditional instructions and warnings against driving through stop signs and red lights will also be part of Traffic Sign Assist.

Improved Trailer Manoeuvring Assist (TBC for the USA)

Improved trailer maneuvering assistant will be optional, one that can handle freely selectable cornering maneuvers up to 90 degrees. Integrated into MBUX, the new system automatically regulates the vehicle’s steering angle up to a speed of 5 km/h (3 mph) and an uphill grade of up to 15%. Convenience features include the Easy-Pack tailgate for the remote-operated open/close function of the tailgate with a button on the key fob or the switch in the driver’s door or the tailgate’s release handle.

New Safety systems

A myriad of active and passive safety features will be available in the 2023 Mercedes GLC, with new, upgraded, and carried-over technologies to make it the safest C-Class-based SUV. One of the highlights is the Pre-Safe Impulse Side, which forms a sort of virtual crumple zone in the event of an accident. The driver or front passenger has moved away from danger before the crash when the system detects an imminent side collision. There are air chambers in the side bolsters of the front seat backrests, and they inflate within the blink of an eye when required.

An updated Active Distance Assist DISTRONIC maintains a preset distance from vehicles in front at speeds up to 60 mph instead of 30 mph previously. Lane detection is a new feature of Active Steering Assist, and it works at speeds up to 130 mph. It recognizes an additional lane with the 360-degree camera and particularly provides advantages in the low-speed range. Increased lane-centering on highways is another advantage of Active Steering Assist.

2023 Mercedes GLC dimensions

The GLC hasn’t changed drastically from the previous model on the dimensions front. The 2023 Mercedes GLC is 2.4 in. longer than its predecessor. Also up are the track widths, 0.24 in. at the front and 0.91 in. at the rear. The overhangs are longer at both front (+ 0.59 in.) and rear (+1.3 in.). The redesigned model has a lower drag coefficient of 0.29 Cd (2022 GLC: 0.31 Cd).

Customers can expect noticeable improvements on the inside. Mercedes-Benz has addressed a big shortcoming of the GLC, the space for rear-seat passengers and luggage. Increasing the wheelbase by 0.59 in. was the first step. Thanks to the larger rear overhang, the trunk capacity has increased by 2.5 cu. ft., which is a significant improvement.

2023 Mercedes GLC powertrain

Mercedes-Benz has started distancing itself from large engines in mid-size models to prepare for an all-electric future. Customers desiring performance will have to opt for hybrid powertrains during this transition. The company employs electrification with mild-hybrid and plug-in hybrid technologies to achieve higher performance and meet new emission targets.

Electrification is standard across the 2023 GLC range. In the U.S., customers will be able to select between GLC 300 (RWD) and GLC 300 4MATIC (AWD) mild-hybrid variants and a yet-to-be-announced plug-in hybrid variant.

The GLC 300 and GLC 300 4MATIC share the M254 2.0-liter gasoline engine that produces 258 hp at 5,800 rpm and 295 lb.-ft. of torque at 2,000-3,200 rpm. A 48-volt battery pack and an integrated starter-generator enable mild-hybrid technology functions such as gliding, boost, and recuperation. The ISG gives a boost with 23 hp of extra power and 148 lb.-ft. of additional torque.

The 9G-TRONIC 9-speed automatic is standard equipment in the 2023 GLC. The electric motor and power electronics lie inside the transmission housing. The thermal management of these two components happens via the transmission cooling system.

2023 Mercedes GLC Plug-in Hybrid

Mercedes-Benz Group has stopped developing new plug-in hybrid systems, but it’s not going to stop selling PHEVs anytime soon. Markus Schafer told Handelsblatt at the 2021 Munich Motor Show (IAA 2021) that the company has “no further new developments planned” regarding plug-in hybrid tech and has made all the relevant investments it was going to make. So, the future GLC PHEV gets existing powertrains. Schafer is a BoM member of Mercedes-Benz Group, CTO responsible for R&D and Procurement.

Mercedes-Benz hasn’t detailed the U.S-spec 2023 GLC Plug-in Hybrid yet, but we believe it could come in one of the two internationally announced gasoline variants: GLC 300e 4MATIC and GLC 400e 4MATIC. Both may deliver an electric range of over 62 miles as per WLTP. The targeted EPA-est. electric range could be around 50 miles.

2023 Mercedes GLC Plug-in Hybrid (gasoline) specifications in Europe

The 2023 GLC Plug-in Hybrid has an 11 kW on-board charger (3-phased) charger as standard. Customers will be able to recharge its battery pack with an optional 60 kW DC charger quickly in around 30 minutes.

Plug-in hybrids accused of ‘greenwashing’

Environmental activists have criticized PHEVs for causing harm to the environment rather than saving it. They claim that customers primarily drive them on fossil fuel, making their carbon dioxide emissions higher than a regular ICE vehicle, as they are heavier because of the extra weight of their traction battery pack.

With an EV mode range of around 100 km or 62 miles, Mercedes-Benz Group wants to make PHEVs usable as an EV. Ola Kallenius, Chairman of the Board of Management of Mercedes-Benz Group, has told Automotive News Europe that the criticisms about PHEVs are on the basis of data of the first-gen PHEVs featuring smaller batteries and thus shorter EV range. Now, with larger batteries that store more energy per charge, customers can drive them as an EV regularly, and some even use the EV mode for their work commute for an entire week.

2023 Mercedes GLC release date

Western European dealers will start receiving the 2023 Mercedes GLC in autumn 2022. The U.S. launch may take place at the end of 2022 or in early 2023.

The auto industry is reeling from a shortage of semiconductors, which has hampered production schedules and new product launches. The war in Ukraine has also affected automakers, as their suppliers (making wire harnesses and interior parts) have had to pause production. Hence, there is an air of unpredictability around the production start of cars in 2022.

The prices of the 2023 GLC in the U.S. could start at just under USD 48,000. Mercedes-Benz says it has significantly upgraded the standard equipment of the GLC, and we already mentioned many of them in the earlier sections. In addition to the large displays, wireless charging, heated front seats, Easy-Pack tailgate, will be standard.


From the next generation, the GLC will roll out of the Mercedes-Benz Sindelfingen plant in addition to the Mercedes-Benz Bremen plant. This production site is currently responsible for the E-Class, S-Class, and EQS. Bremen will get a head-start, while Sindelfingen, as per a report JESMB published on November 2, 2021, should start production at the end of 2022. The Beijing plant would continue building the GLC, with local adaptations, for the Chinese market. A report JESMB released on November 29, 2021, suggested that the next-gen GLC would remain on sale for about seven years, until 2029.

GLC sales performance

The GLC is Mercedes-Benz USA’s best-selling vehicle this year. In Q1 2022, the company sold 16,910 units, an 8.6 percent improvement over Q1 2021 (15,569 units). In 2021, the American subsidiary sold 51,805 GLCs, down by 1.6% YoY (2020: 52,626 units).

Next-gen Mercedes GLC Coupe

The 2023 Mercedes GLC Coupe will debut as the sporty alternative to the mid-size luxury SUV in spring 2023, as per a report JESMB published on June 11, 2022. The aesthetic and technical relationship between the standard SUV and the SUV-coupe versions should be the same as that of the first generation.

First spy shots of the 2023 Mercedes GLC Coupe surfaced online earlier this year, revealing key design changes on the outside. The new model has a more dynamic exterior, achieved with a sharper beltline. Additionally, the tail lamps are sleeker and feature different graphics than the current model. We have yet to see the inside of the cabin, but we can safely assume that the interior design would be similar, if not identical, to the SUV version.

The report says that customer deliveries of the next-gen GLC Coupe will start nearly a year after the all-new GLC SUV starts arriving at dealers. Expect the 2023 GLC Coupe on sale in the first markets in late summer 2023. In the U.S., the next-gen GLC Coupe may arrive as an MY2024 model. In that case, the current generation should continue for one more model year (MY2023).

2023 Mercedes-AMG GLC hybrid

The next-gen Mercedes GLC line-up will include performance-oriented AMG variants. According to an Autocar report, the GLC 43 and GLC 63 arrive in 2023. Both the AMG variants of the next-gen GLC will use the same four-cylinder gasoline engines as the next-gen C 43 and C 63 cars, with the GLC 63’s engine producing more than 500 hp.

The next-gen GLC 63 AMG will reportedly get the M139 2.0-liter engine with plug-in hybrid tech. There would be three different electrical assistance systems for the engine: an electrified turbocharger, an ISG, and a traction motor. The hottest version of the GLC could arrive in the first markets in the summer of 2023. According to the JESMB report dated November 2, 2021, the next-gen GLC 43 AMG will be a mild-hybrid with a 20 PS (20 hp) ISG assisting a 390 PS (385 hp) M254 gas engine, says the German blog.

2023 Mercedes-AMG GLC rendering’s exclusive rendering of the next-gen Mercedes-AMG GLC 63 with a sporty grille, bumper, badge, alloy wheels, brake caliper and other styling changes.

Motor1’s spy photographers have spotted the all-new Mercedes-AMG GLC 63 during testing. It sports the usual dose of AMG goodness like an exclusive (Panamerica) grille, lowered ride height, beefier brakes, sportier wheels, and more aerodynamic bumpers.

Our exclusive rendering (pictured above) shows how the next-gen GLC 63 with the new design could look. We’ve given it the AMG Panamericana radiator grille with a gloss black surround, an A-shaped lower grille, and large outer air inlets similar to the prototypes in spy shots. On the sides, the multi-spoke alloy wheels with red calipers, and black mirrors communicate the high-performance SUV’s character.
