Confirmation that these test cars are running an electric drivetrain comes with the fact no engine noise was heard by photographers. Additionally, a photo of the GLC’s nose with the bonnet open shows its lack of engine and there's no condensation or smoke from the car’s tailpipes. Final proof comes with an orange window sticker displaying an electricity lightning symbol (shown in the gallery).
The cars were spotted running with large battery packs, thought to be lithium ion. Mercedes has previously stated that its future models would be capable of travelling up to 310 miles between recharging.
As with AMG, Smart and Maybach, EQ is set to become a sub-brand within the Mercedes-Benz group. Four models are planned to be launched in 2019. The first, an SUV, will introduce the new EVA platform. It was previewed by the Mercedes Generation EQ concept of Paris last year, which produced 402bhp.
Mercedes aims to have 10 EV models on sale by 2025, at which time it expects to have as much of 25% of sales allocated to these zero-emission models.
