Electric variant of the C-Class to be the first to arrive under Mercedes-Benz’s “entry luxury” branding.

The first of the next-generation Mercedes-Benz entry-point models will arrive in 2024 as a four-door CLA-sized sedan with tech from the super-efficient Vision EQXX concept.

Confirmed to Automotive Daily Network partner Autocar by the brand’s head of exterior design, Robert Lesnik, the currently unnamed car will be the first to be released as the first under the marque’s “entry luxury” branding and be around 4.7 metres long.

Essentially an electric equivalent of the ICE-powered Mercedes-Benz C-Class sedan, it will provide Mercedes with a long-awaited executive EV to rival the likes of the Polestar 2, BMW i4 and indomitable Tesla Model 3.

When it arrives, it will be packed with range-boosting tech from the over-1100km-range concept, which Mercedes chief technology officer Markus Schäfer previously said would “make it one of the most efficient electric vehicles that exists”.

An AMG variant will come a year later, Lesnik confirmed, fitted with some of the EQXX’s active aerodynamics, such as its moving diffuser. It will also get an active spoiler.

The sleek EQXX will also form the look of the new “entry luxury” range, Lesnik said, with visual inspiration coming from the concept. The AMG variant will most likely get its own, more aggressive styling.

It will be one of the first to use the brand’s upcoming Mercedes-Benz Modular Architecture (MMA) platform, conceived for small and mid-sized EVs.

When it arrives, it will be the one of the first pieces of the brand’s radical new electric plan, which includes ushering in electric options in crucial new segments and introducing a range of new platforms with unprecedented range and performance capabilities.

The marque’s line-up of electric models already comprises a wide variety of cars of different shapes and segments – ranging from the Mercedes-Benz EQA hatchback to the new Mercedes-Benz EQS flagship – and it will be extended further with the launch of electric version of the Mercedes-Benz G-Class 4×4 by 2024.

The company’s commitment to offering a electric version of every model by 2025 is among the most ambitious electrification pledges of any mainstream manufacturer. This comes alongside a commitment to develop only bespoke EV architectures from 2024 – starting with the MMA.

One of four new EV architectures being developed by engineers in Stuttgart as part of the wide-reaching electric offensive, the MMA will be instrumental in future-proofing some of Mercedes’ best-selling and most crucial models.

Last year, Schäfer told us the MMA platform will be used for compact cars but “has the potential to reach into the mid-size segment as well” and confirmed the potential for a dedicated EV offering in the mid-sized executive sector.

The current C-Class is one of the few remaining legacy Mercedes models without a direct EV equivalent, but the plug-in hybrid Mercedes-Benz C300e has one of the longest electric ranges of any PHEV on sale, at an official 109km, and the recently launched EQE sedan helps to fill the gap between the C-Class and the EQS electric limousine.

Likewise, Mercedes’ existing bespoke EVs are among the longest-legged in their respective segments, but the new-generation EVs will take this further. They will combine power-dense battery packs with hyper-efficient motors, lightweight construction methods and super-slick bodywork to fully maximise efficiency, as demonstrated by the radical (and fully functioning) EQXX prototype, which gives the most concrete clues yet as to the electric future of the popular C-Class.

Company bosses have already admitted the Mercedes-Benz EQXX will not directly evolve into a production car, but in its conception, design and capability, it serves to preview Mercedes’ future line-up, and in its positioning, it is more closely related to the C-Class than any other model. So while the eventual production descendant of this concept will be larger (the EQXX is just 1350mm tall and a full 162mm shorter than the EQE) and more conventionally styled, it will remain true to the core characteristics.

The main aim of the EQXX project was to show how far an EV designed to these principles can travel on one charge – and the real-world range of the concept, as demonstrated on real roads, at normal speeds and in changeable conditions by Mercedes, nudges 700 miles. That represents a marked improvement not just on the 729km EQS but also every mainstream electric vehicle on sale today.

Mercedes-Benz highlights radical new battery technology as a facilitator of this improvement, with boosted power density allowing for a greater range to be achieved while keeping weight low and maximising interior space. The firm remains tight-lipped about the technical specifics of the new-generation power packs it will begin rolling out to its line-up, but the EQXX’s circa-100kWh battery – supplied by CATL – is 35 per cent lighter and about half the size of the 107.8kWh unit used by the EQS. Such advances pave the way for future cars to sit lower and have more spacious cabins, as well as offering improved ranges.

Another key component of the MMA platform will be the integration of a new-generation electric motor that dramatically boosts efficiency while, like the battery, freeing up space in the chassis and reducing weight. The lower kerb weight of the new electric C-Class saloon, relative to its larger sibling models, means it will offer comparable straightline performance to Mercedes’ existing EVs even when fitted with lower-powered and more efficient motors.

Aerodynamic efficiency plays a fundamental role in eking out more miles per charge, so the electric C-Class will bear a much more rakish and low-slung silhouette than the current car – and it is likely to sit higher than the EQXX for easier ingress and egress. A coupé-esque sloping roofline will probably be the most obvious differentiator from the current three-box saloon and the glasshouse will need to be substantially wider than the concept’s to allow for three seats across the back row – and comparable storage space.

Whether, like the current C-Class, the new executive EV will be offered in wagon guise is less certain. Mercedes’ combustion-powered answer to the BMW 3 Series Touring wagon has historically been a strong seller, particularly in Germany, but a marked rise in the popularity of SUVs threatens the viability of traditional estate models in the new electric era. They are “technically absolutely possible – that wouldn’t be a problem”, said Schäfer recently, but in keeping with a continuing rationalisation of the Mercedes-Benz line-up, these models could be indirectly replaced by a new range of more popular, equally capacious and barely less aerodynamic SUVs.

Mercedes-Benz solid state batteries are on the way

While touting a 50 per cent improvement in energy density from its next-generation batteries, Mercedes is already looking to the next step, with development underway on solid-state battery technology.

The firm has partnered Taiwanese battery developer Prologium, which claims to have supplied nearly 8000 solid-state battery samples to car manufacturers. The tie-up will usher in solid-state test vehicles in “the coming years” on the way to rolling out the hardware to production cars in the second half of the decade.

Mercedes estimates that these future batteries can nearly double the range of today’s conventional lithium-ion packs and the EVs equipped with these units can be lighter, more spacious and cheaper to produce.
