BMW i3 and Mercedes C-Class EQ: The Electric Sedan Battle Heats Up

The premium electric sedan segment is about to receive a lot more competitive. BMW has recently unveiled the BMW i3, built on its new Neue Klasse platform, and Mercedes-Benz is poised to respond with an electric version of the C-Class, slated for preview next month. This rivalry is shaping up to be a key battleground in the evolving automotive landscape.

A New Generation of Electric Sedans

The arrival of the BMW i3 isn’t simply an electric adaptation of the existing 3 Series; it’s a distinct model. Mercedes-Benz is countering with an electric C-Class, also utilizing a dedicated platform separate from its combustion engine variants. The competition is heating up as both manufacturers aim to deliver cutting-edge electric vehicles.

Dimensions and Platform Differences

The BMW i3 and Mercedes CLA EQ are closely matched in size, with the i3 being only 4 centimeters longer at 476 cm compared to the CLA’s 472 cm. Width and height are nearly identical, measuring 187 cm wide and 148 cm high, with the i3 exceeding the CLA by just one centimeter in both dimensions. The i3 boasts a longer wheelbase of 290 cm versus the CLA’s 279 cm, potentially offering greater interior space.

These differences are largely attributable to the platforms on which they are built. The i3’s New Class platform is designed exclusively for electric vehicles, eliminating the compromises inherent in accommodating internal combustion engine components. Conversely, the CLA EQ’s MMA architecture is shared with the model’s thermal variants, requiring accommodation for various mechanical parts.

Design and Aesthetics

The BMW i3 embraces the Neue Klasse design language, featuring classic proportions with an elongated hood and a set-back passenger compartment. The design emphasizes a more essential aesthetics, moving away from excessive ornamentation. The front grille is now thinner and more horizontal, integrating seamlessly with the headlights and sensors for a cleaner gaze. The bodywork is smooth and aerodynamic, utilizing flush handles, whereas the rear is defined by slim, three-dimensional taillights. The iconic Hofmeister elbow remains a defining feature of the window line.

The Mercedes CLA also showcases a new design direction for Mercedes-Benz. The front features a low, inclined profile with a closed grille illuminated by numerous small stars and a backlit logo. The headlights have a distinctive star-shaped light signature connected by a thin LED strip. The sides are fluid with retractable handles, and a panoramic glass roof comes standard. The rear echoes the starry motif of the front with a continuous light band.

Interior and Technology

The interior of the BMW i3 prioritizes sustainability with recycled materials and a minimalist design. Physical controls are minimized, concentrating functions within a digital ecosystem. A key innovation is the BMW Panoramic Vision, a screen extending across the base of the windshield, replacing the traditional dashboard. This system displays customizable data manageable via a large 17.9-inch central screen, similar to smartphone logic.

The Mercedes CLA interior is brightened by a standard panoramic roof. The dashboard features a single transparent, backlit surface integrating three displays: a 10.3″ instrument cluster and two 14″ screens for infotainment and passenger use. These screens support streaming and video games via Bluetooth, with software mirroring smartphone functionality and gesture controls. A high central tunnel provides storage and USB-C ports, with physical buttons limited to seat adjustments on the door panels.

Performance and Range

The BMW i3 launches with a 50 xDrive all-wheel-drive version, delivering 469 CV and 645 Nm of torque, achieving 0-100 km/h in 4.7 seconds. It utilizes a sixth-generation eDrive system with a rear synchronous and front asynchronous motor. The battery pack, featuring new high-density cylindrical cells, promises a range of 900 km and supports ultra-fast charging up to 400 kW, adding 400 km of range in approximately 10 minutes.

The Mercedes CLA EQ is built on the MMA platform and supports fast DC charging at 320 kW. It’s available in two variants: the 250+ rear-wheel drive (201 CV) and the 350 all-wheel drive (354 CV). A unique feature is a two-speed gearbox for the rear engine, optimizing both acceleration and efficiency. The declared range is between 672 and 792 km, depending on the configuration.

Pricing

Official pricing for the BMW i3 has not yet been released, but estimates suggest a price around 65,000 euro, similar to the starting price of the iX3. The Mercedes CLA EQ 350 4Matic starts at 62,265 euro, with the 250+ beginning at 56,665 euro. The question remains how the C-Class EQ, expected to be positioned higher than the CLA, will be priced.
