Prototype ride: 2026 Mercedes-Benz CLA EV rethinks regen braking

  • The 2026 Mercedes CLA EV gets true one-pedal driving

  • Mercedes put a focus on efficiency and energy recuperation with the CLA EV

  • Mercedes hasn’t said how much the 2026 CLA EV will cost; it debuts in 2025

Up until now, many automakers have chosen to dial back regenerative braking in EVs because of concerns over stability on slick roads. 

Mercedes-Benz is breaking from that thinking in its future EVs, starting with the next-generation system that will debut in future EVs starting with the CLA EV. 

During a brief ride in a 2026 Mercedes-Benz CLA EV prototype in the Austrian Alps, Timo Stegmaier, senior manager of electric drive systems for Mercedes, and Tom Steller, a spokesperson for the automaker, demonstrated the next-gen EV’s braking and propulsion systems in near-whiteout blizzard conditions. 

Here’s what I learned.

2026 Mercedes-Benz CLA EV focuses on one-pedal driving

The Mercedes team emphasized that it’s heard feedback from customers and media alike, loud and clear, regarding the EQE and EQS EV’s braking systems and their moving friction point and unpredictably varied pedal feel. 

They started out as some of the worst brakes on the market and have, through software updates, become…acceptable. That won’t be the case with the CLA EV, I was told. In November Mercedes engineers confirmed to Green Car Reports the brake pedal in the CLA EV will never move unless the driver touches it.

The CLA EV will have three regenerative braking modes including D-, D, and D+. A fourth bonus mode will be D Auto. Full one-pedal max regen kicks in with D- mode, which we used the entire prototype drive, and the others subsequently lessen the regen. 

D Auto mode automatically adjusts the regenerative braking system for the conditions. In the 2025 Mercedes-Benz E 53 Hybrid, for instance, it’s tied into the adaptive cruise control and safety systems to be fully variable. It’s not consistent or predictable. But it’s unclear as of yet how D Auto works in the CLA EV.

The mountain roads were covered in blowing snow over black ice. No matter how quickly Stegmaier selected the most aggressive brake regen with D-, and let off the accelerator, but the Michelin Alpin 5 winter tires never seemed to break traction. The regenerative braking system used the next-gen MMA electric architecture’s PCUs and ECUs to react instantaneously and adjust accordingly. The car pointed straight under braking and mid-turn didn’t change composure. Very impressive. Some humans aren’t this smooth in these conditions.

For reference, Snow or Winter or Slippery Conditions drive modes in almost all EVs on sale today typically reduce or disable regenerative braking. This is to ensure the tires don’t break traction and the car remains stable on slippery surfaces. 

A Mercedes spokesperson told GCR that Stegmaier’s recommendation to use max recuperation in slippery conditions is specific to the CLA EV because of its use of next-gen sensors. The system in the CLA is designed to automatically adjust to road conditions, optimizing safety and efficiency instantaneously. From what I observed it did just that. 

The EQE and EQS lineup use different platforms, electrical architectures, and sensor packages along with control systems and software. These current EVs manage traction and braking behaviour differently, and aren’t as focused on maximizing recuperation or efficiency in real time.

The CLA’s capable of 200 kw of recuperation before engaging the friction brakes. Stegmaier told me that the CLA EV prototype never used the friction brakes during our drive. Impressive.

That energy goes back into the 85.0-kwh (usable) battery pack through an 800-volt electrical architecture. Mercedes said fast-charging will top out at 320 kw and the CLA EV will be capable of adding 186 miles of range in 10 minutes. That’s starting out at a 10% state of charge, and translates to approximately 36 kwh of energy. Charging from 10-80% will take less than 22 minutes. There will also be an 11.0-kwh onboard charger for Level 2 AC charging.

2026 CLA EV feels quick, comfortable, and planted

When Stegmaier put the accelerator to the floor the tires didn’t spin. The CLA EV prototype simply shot forward, but given the conditions the engineer didn’t keep the pedal buried long. The car remained pointing forward despite the slippery surface, I didn’t see the steering wheel tug in either direction, and seemingly, the electronics adjusted power in real time for the conditions.

The dual-motor prototype has Mercedes’ new EDU 2.0 (Electronic Drive Unit 2.0) hardware under its metal skin, including silicon-carbide inverters. The rear motor is a 268-hp synchronous motor (PSM) paired with a 107-hp motor up front. I couldn’t perceive if the front motor was on or off, but given the conditions it’s hard to imagine it wasn’t engaged most of the time.

Mercedes hasn’t talked about performance, but a 0-60 mph time in the low 4-second range seems about right. Single-motor models will surely be slower and hotter AMG models surely quicker.

Except for the single switchback corner Stegmaier purposely hung the tail out during, it felt from the passenger seat that torque was kept under control partly by soft inputs from the driver. 

The new in-house-designed 2-speed automatic transmission may have shifted into second gear to soften torque delivery. The unit is capable of staying in first gear up to 68 mph, but it’s variable based on conditions and needs. It was smooth and with the blizzard there was a lot to take in quickly.

The prototype rode on a conventional (non-active) suspension, which was comfortable, compliant, and controlled. Stegmaier wouldn’t talk details and didn’t mention whether higher trims or AMG models would offer adaptive dampers, but the prototype I rode in was as comfortable, if not more so, as the larger C300 I had just piloted.

2026 Mercedes-Benz EV charts its own course

The exterior of the CLA EV was completely covered in camo, but it clearly looked like the concept that previewed the next-gen EV In 2023. Right down to stars in the LED head and taillights.

Inside the dashboard and door panels were covered in black cloth. Kindly, Mercedes asked me to not comment on what little I saw or touched. But I can say the dashboard seems to be completely different than today’s EQE and EQS lineup. The high-mounted yacht-like setup is gone. The dashboard seems to be short and tight up against the cowl. It reminded me of the Mercedes 190E and W126 S-Class from the ‘80s and ‘90s, or even the G-Class of today.

Mercedes didn’t let me behind the wheel of the CLA, and my time both in and around it was brief. Still, what I saw, experienced, and felt proved Mercedes has listened to feedback about its current EVs, is focused on efficiency, and aims to make the 2026 CLA EV the starting point for its next-gen electric cars. 

Mercedes-Benz paid for travel, lodging, and was shocked I wasn’t cold during a blizzard to bring you this first-hand review.

Range-boosting solid-state EV cells get right-sized for production

Massachusetts-based Factorial has introduced a process for manufacturing solid-state battery cells, in the size range that electric vehicles can use, that is also close to what can be used for mass production.

The company has been providing test cells to automakers, but on Thursday announced that it had scaled sample cells to an “automotive-relevant” 40-amp-hour capacity and was using a dry-coating process that it claims maximizes energy density while minimizing operating costs and the environmental impact of battery production.

The dry coating process eliminates all hazardous solvents, Factorial said in a press release. The coating process is also less energy-intensive than conventional manufacturing processes, Factorial claims, while the solid-state chemistry eliminates the need for a formation process used with liquid-electrolyte chemistries for a further reduction in energy use.

Factorial noted that it used customized equipment at its Massachusetts development center to establish the dry coating process, but that provides a template for manufacturing at proper battery factories, like the one Factorial announced in 2023. And in terms of durability, Factorial claims smaller prototype cells have already reached over 2,000 charge and discharge cycles.

Factorial counts Hyundai, Mercedes-Benz, and Stellantis among its investors. Earlier this year it announced that cells developed in collaboration with Mercedes could boost range by up to 80% through greater energy density. More recently, Factorial confirmed that Stellantis will test its solid-state cells in a fleet of Dodge Charger Daytona EVs starting in 2026.

Other automakers have shown interest in solid-state batteries. Toyota announced earlier this year that it planned to begin manufacturing them in 2026 or soon after, albeit likely in low volumes. But Factorial appears to be making progress toward manufacturing solid-state batteries in commercially relevant volumes.

Study: Only 1% of EV buyers would go back to gas-powered cars

Study: Only 1% of EV buyers would go back to gas-powered cars

Once someone buys an electric vehicle, they tend to stick with it, according to a new survey from the Global EV Alliance, which represents EV driver associations in 38 countries.

The survey found that 92% of current owners plan to buy another EV as their next car. Just 1% said they would opt for a gasoline or diesel car if they had to replace their EV tomorrow, while 4% said they would consider a plug-in hybrid as a replacement for their EV.

PHEVs include a gasoline engine, but after already owning a fully electric model drivers might tend toward seeing it as a backup source.

The survey is based on 23,000 responses from 18 countries gathered between Aug. 27 and Nov. 20, 2024. Those results were weighted based on each country’s share of the total EV fleet. For example, U.S. results were weighted up, and Sweden’s weighted down, to reflect the relative size of each country’s share of the EV fleet, the Global EV Alliance explained in a press release.

Low operating costs were the main reason for owners’ loyalty to EVs, with 45% of respondents listing this as their main reason for intending to buy another EV. Other important factors included the lower climate impact of EVs (40%), and that EVs are “good for the local environment and make less noise” (32%).

Those results appear encouraging for EV adoption, but with surveys like this there is still much that is up for interpretation, including the phrasing of questions when asking consumers what they plan on buying after their first EV—and whether it truly replaces an EV or another vehicle in the household.

A 2023 study from S&P Global Mobility found that, Tesla aside, nearly half of EV-owning households still purchased an internal-combustion vehicle the next time around, in part due to lack of suitable EV options from non-Tesla brands. And the Department of Energy earlier this year noted that U.S. EVs are driven fewer miles than internal-combustion vehicles, meaning they might not always be serving as like-for-like replacements.

Mercedes-Benz electric van concept coming in spring 2025

Mercedes-Benz will preview its Van.EA electric van architecture with a concept vehicle this spring.

The automaker confirmed plans for the van concept Friday, releasing a teaser image indicating that, despite its dedicated EV platform, the concept and the next-generation electric vans it heralds will look like exactly what they are.

Van.EA will be the first EV-specific architecture for Mercedes vans, although the automaker currently sells the eSprinter, as well as a handful of smaller Europe-only models, based on combustion-vehicle architectures.

Mercedes showed photos of camouflaged prototypes out testing in October ahead of a 2026 production launch. Mercedes intends for every new electric van it introduces after that point to use the Van.EA platform, which is designed around a shared set of components and modules to accommodate midsize and large vans.

Those modules will include three main sections, with front and rear sections able to house electric motors. Single-motor models will be front-wheel drive, but dual-motor all-wheel drive will also be available.

Mercedes is also planning for a variety of applications, from work vehicles like cargo vans to a U.S.-bound electric luxury van. Mercedes has also discussed the potential for electric RV conversions, addressing what is already a lucrative market for the automaker’s gasoline and diesel vans.

Van.EA is one of several new EV architectures Mercedes plans to introduce over the next few years, alongside the MMA platform for compact cars like the 2026 Mercedes CLA, and the AMG.EA platform to be used by EVs from the automaker’s AMG performance division, including a fastback sedan and an electric SUV.
