CLA estimated average
These curves are aggregated, owner-reported degradation data — not official manufacturer figures. Your own result above is the number that matters.
Wh/mi or Wh/km
On the MBUX display, navigate to "Vehicle" → "EQ" → "Energy Flow" (or "Consumption"). Average consumption in kWh/100 km or Wh/mi is displayed. On models with the MBUX Hyperscreen, swipe to the energy consumption widget.
Estimated Range
Estimated range is shown on the instrument cluster (digital display) and in the MBUX "EQ" → "Range" section, which also shows range by driving mode.
Battery Percentage
Battery percentage is displayed on the instrument cluster next to the range, on the MBUX home screen, and in the EQ menu.

About the Mercedes-Benz CLA
The Mercedes-Benz CLA marks the debut of Mercedes's new MMA (Mercedes Modular Architecture) platform, purpose-built for electric and electrified vehicles. This is arguably the most important new Mercedes in years — a compact electric saloon designed to compete directly with the Tesla Model 3 at a more accessible price point than the EQE.
The 85 kWh NMC battery targets a remarkable 400 miles of WLTP range, which would make it class-leading if achieved. Mercedes has focused heavily on efficiency, with a low drag coefficient and an advanced electric drivetrain that uses a new generation of permanent magnet motors. DC fast charging at up to 250 kW should deliver a 10–80% charge in around 22 minutes.
The CLA also debuts Mercedes's new MB.OS operating system, replacing the existing MBUX infotainment. The interior represents a design evolution with a focus on sustainability materials and simplified controls. Mercedes is betting heavily on this platform to deliver the volume sales needed for its electric transition.
What the press thinks
Early assessments praise the CLA's efficiency, projected range, and the promise of the new MMA platform. The MB.OS infotainment system shows potential. Reviewers are cautiously optimistic but note that real-world range and final pricing will determine whether it can genuinely challenge the Tesla Model 3.
