Mercedes-benz has revealed the Concept CLA with an all-new electric powertrain that provides a range of up to 466 miles.

Debuting a year ahead of the new production CLA, the Concept CLA utilises the new Mercedes Modular Architecture (MMA) that will underpin a whole family of new models.

The Concept CLA uses a 238PS electric motor, with a two-speed transmission. It's powered by a new type of battery, which is lighter and smaller than existing units.

By implementing an 800v electrical system, Mercedes says the Concept CLA can add 248 miles of range in just 15 minutes at a suitable (250kW) rapid charger.

The highly-efficient powetrain and aerodynamic body enable the car to achieve 5.2mi/kWh efficiency while driving.

Ola Källenius, chairman of the Board of Management of Mercedes-Benz Group AG, said: “The Concept CLA Class is the forerunner for an entirely new all-electric segment of entry-level vehicles at Mercedes-Benz. The range will comprise a total of four new models – a four-door coupé, a shooting brake and two stunning SUVs – each with significantly elevated product substance. This new model family is inspired by a generation of car buyers who want that unmistakable Mercedes-Benz feel, with more features, even greater comfort and safety and the most advanced technology."

Externally, the Concept CLA shares a familiar silhouette with the current CLA model. It's styling is enhanced with wrap-around LED lighting, 21-inch wheels and one-piece glass roof that integrates with the rear windscreen.

The interior is familiar with the existing CLA too, but incorporates a Mercedes Superscreen layout that stretches the infotainment screen and instrument cluster across the entire dashboard.

The driver assistance and safety systems under development for the MMA platform make it possible, for example, to drive partially automated (SAE Level 2) on virtually all types of roads, to aid the driver when changing lanes on multi-lane roads, to automatically manoeuvre into and out of tight parking spaces, and to prevent or reduce the severity of collisions in an increasing number of situations.

Future SAE Level 2 applications are also prepared for the use of LiDAR-supplemented sensing technology to meet the high operational complexities and safety demands of urban traffic. In this segment, these powerful sensors will enable customers to equip their vehicle with a wide range of SAE Level 2 features. It will be possible to enhance these via over-the-air updates, even after vehicle purchase.

The MB.OS software and its computing power is generally ready for an SAE Level 3 system upgrade for vehicles equipped with a comprehensive sensor set including a LiDAR sensor and redundancies for vital vehicle systems.
