Mercedes-Benz has updated the EQS and boosted its range to beyond 500 miles.

The high-power long-range luxury electric car sits alongside the S-Class as the brand's flagship electric model.

Battery capacity has increased from 108.4kWh to 118kWh, enabling a range of 510 miles for the EQS 450+ version (UK specs TBC).

Mercedes has also added a heat pump to the standard equipment list, to help boost efficiency, while a software update will be rolled out soon to alter the regenerative braking system in order to better maintain the car's friction brakes.

The rear-wheel-drive EQS 450+ produces 333PS, which is enough to deliver a 6.2-second 0-62mph acceleration time.

Visual changes are limited to the introduction of a new grille, that resembles a more traditional chrome slatted design.

An all-wheel-drive EQS 53 AMG model delivers a more potent 658PS output thanks to a twin-motor all-wheel-drive setup.

When it comes to charging, the EQS 450+ is capable of adding 186 miles of range in 15 minutes, using a 200kW rapid charger.

Mercedes claims the EQS is the most aerodynamic production car in the world, helping to boost its range and reduce unwanted cabin noise.

The EQS is based on a new modular platform designed specifically for electric vehicles. It rides on air suspension and features a four-wheel steering system.

Inside, the dashboard is dominated by the MBUX Hyperscreen, which is now fitted as standard. It combines three displays to provide a panoramic digital cockpit. There are digital instruments for the driver, a larger 17.7-inch central infotainment section and a separate display for the passenger. Rear-seat passengers can also benefit from a pair of 11.6-inch displays.

Connected services enable over-the-air software updates, while the system also features the ability to unlock or upgrade additional features.

Pricing for the EQS starts at £112,610. The updated model will be available from 25 April.
