Opel has updated the Rocks.

The battery-electric quadricycle now gets a black front 'Opel Vizor', while the car's logo is now in white, bringing the Rocks closer to the rest of the cars from Opel's range.

The Opel Rocks also now gets a light grey body, although its roof and wheels stay a contrasting black, a move said to reflect the brand's 'Detox' design philosophy.

In the cabin, the Opel Rocks now comes with a redesigned steering wheel, with the Opel Blitz logo in white on a black background. The battery-electric quadricycle continues to come with a panoramic roof and a smartphone holder.

Rocks drivers can also connect their smartphone via Bluetooth via the separately attachable 'MyRocks Switch' on the steering wheel to listen to their favourite music, use their favourite navigation system and make phone calls without taking their eyes off the road.

The Opel Rocks offers a 75km range and a top speed of 45km/h and is charged via a normal household socket.
