    Mercedes CLA EQ Test Drive: Performance of the 800-Volt Sedan

    Key Takeaways

    1. The all-electric Mercedes CLA EQ is currently available as a sedan, with a Shooting Brake version set to launch in early 2026, followed by internal combustion engine options.
    2. Interior quality is high, featuring a sturdy design, but some areas have hard plastic, and the touchpads on the steering wheel can be difficult to use.
    3. The driving experience offers impressive acceleration, low interior noise, but the artificial driving sound can be irritating, and the chassis may feel spongy at higher speeds.
    4. Efficiency is notable in city driving, averaging around 13 kWh per 100 km, suggesting a potential city range of about 600 km (373 miles).
    5. The 800-volt technology allows rapid charging speeds up to 320 kW, enabling a charge from 10 to 80% in 22 minutes, but it currently cannot be charged at 400-volt stations until a solution is provided next year.


    With the launch of the CLA EQ, Mercedes is stepping into the next generation of electric vehicles. Right now, the all-electric CLA is only available as a sedan, but a Shooting Brake version is set to debut in early 2026. Later, options with internal combustion engines will be introduced. During a three-hour test drive, we experienced the CLA 350 4Matic EQ in both urban and highway settings. This model features the Progressive trim, 17-inch wheels, an 85-kWh battery, and offers up to 349 hp.

    Initial Impressions

    Our first look at the Mercedes EV was quite positive, especially since the automaker has included a reasonably sized frunk. From what we observed, it’s ideal for storing the charging cable, which otherwise takes up too much room in the trunk. Upon entering the car, you notice that you sit slightly higher than you might expect when viewing the vehicle from the outside. This is due to the battery placement in the underbody, although we would have preferred a slightly lower seat position.

    Interior Quality

    The interior gives off a sense of high quality and sturdiness, though you can find hard plastic in some lower sections. The absence of a high-gloss finish in the center console is a nice touch. Drivers can quickly turn off the speed limit warning by pressing and holding the traffic sign on the touchscreen. However, using the touchpads on the steering wheel can be tricky, leading to multiple incorrect commands. Those who appreciate extensive ambient lighting will likely enjoy this electric vehicle, particularly the numerous illuminated stars on the passenger-side dashboard. Unfortunately, there is no sunshade for the panoramic glass roof.

    Driving Experience

    The “driving sound” is noticeable right away but can thankfully be turned off. In our view, the various sound profiles seem artificial and detract from the driving experience, as they can become irritating quickly. On the plus side, acceleration is impressive, with the claimed 4.9 seconds to 100 kph (62 mph) seeming accurate. The electric CLA also reaches its top speed of 210 kph (130 mph) swiftly. Other positives include low interior noise levels; we could converse easily without raising our voices even at speeds over 160 kph (100 mph). The standard seats are comfy but lack lateral support.

    Chassis Comfort

    The chassis is designed for comfort, effectively absorbing bumps in the road. However, the Mercedes EV feels somewhat spongy at higher speeds, lacking a sense of security and stability. Additionally, the chassis is too soft during cornering, making it feel less sporty. In urban driving, the brakes did not fully impress us either. Just before coming to a complete stop, there was always a slight jolt. Even after halting, we had to keep our foot on the brake for about 2 seconds until the auto hold feature kicked in.

    Efficiency on the Road

    We were pleasantly surprised by the efficiency in city driving. During the afternoon rush hour in the Ruhr area (dry, 16° C / 61° F) with lots of stop-and-go traffic, we averaged around 13 kWh per 100 km, which is pretty good. This suggests a city range of about 600 km (373 miles) is achievable. On our short journey on the Autobahn, where we reached the top speed of 210 kph / 130 mph, the CLA EQ used 20 kWh per 100 km. A more relaxed driving style could certainly conserve more energy.

    Charging Capabilities

    The 800-volt technology enables charging speeds of up to 320 kW, allowing for a charge from 10 to 80% in just 22 minutes, according to Mercedes. However, we couldn’t test these rapid charging features during our brief drive. AC charging supports up to 11 kW, but there’s an optional 22 kW charger available for an additional €654.

    The downside is that as of now, the new CLA EQ cannot be charged at 400-volt stations. A solution for this will be available early next year. The 400-volt charging option is also available on the new Mercedes GLC EQ for €654. The navigation system accounts for this limitation and avoids such stations. Without this option, you would be unable to use many 50 kW chargers at supermarkets or most Tesla charging stations in Germany, for instance.

    With the introduction of the Xiaomi YU7 SUV, the Chinese brand is rolling out a robust electric vehicle that boasts up to 681 HP, an 800-volt system, and an impressive range of up to 835 kilometers. This vehicle made its debut in China on June 24, 2025, and is built on Xiaomi’s own EV platform. It is available in three versions: the standard rear-wheel drive, the all-wheel drive Pro model, and the premium Max variant. Power output varies from 315 kW (428 hp) to 508 kW (681 hp), based on the selected configuration.

    Impressive Charging Technology

    One of the standout features is the 800-volt charging technology, which supports rapid charging at rates up to 5.2 C. Xiaomi claims that this allows the battery to charge from 10% to 80% in only twelve minutes, providing a range of about 620 kilometers after just fifteen minutes of charging. Depending on the variant, the SUV is equipped with batteries that have a capacity of up to 101.7 kWh, making it a formidable competitor in the EV market.

    Luxurious Interior Features

    The interior of the YU7 is also top-notch. It includes a 16.1-inch display, a head-up display wider than 1 meter, and a multitude of digital features that create a ‘connected’ driving experience. Additionally, it comes with an adaptive chassis, several assistance systems (like LiDAR sensors), and a premium cabin outfitted with nappa leather seats and Dolby Atmos sound.

    Targeting Tech-Savvy Consumers

    The Xiaomi YU7 SUV is targeted primarily at tech-oriented consumers in the premium market, yet it remains significantly more affordable than many well-established rivals. Pre-orders commenced in China in June 2025, with the first deliveries expected in the summer. It is uncertain when or if this model will be offered in international markets beyond China. Nevertheless, Xiaomi has expressed a clear intention to launch its electric vehicles in Europe in the future.
