The Vauxhall Monza range-extender concept hints at design features which could be included on new models in the future.

In addition to the looks, Dr. Karl-Thomas Neumann, Opel/Vauxhall chief executive, has said the new focus for Vauxhall is connectivity and efficiency.

The Monza concept does away with a widescreen display on the interior dash and features 18 miniature LED projectors which turn create an interactive display surface, projecting 3D graphics for infotainment and web-browsing. All in car features are activated using voice commands.

There are also three modes of smartphone connectivity: ‘Me’, ‘Us’, and ‘All’. The first setting shuts down all smartphone functions except those expressly wanted for driving, like navigation commands, or music playback.

‘Us’ allows connection between a set group of family members and close friends, while ‘All’ allows anyone with a smartphone or tablet to access the car’s journey information, encouraging car sharing between people travelling to nearby destinations.

The Monza is an evolution of Vauxhall’s Ampera and combines lithium ion battery power with the 1.0-litre petrol from the Adam which runs on compressed natural gas.

The Monza has a power output of 148bhp. If the Monza was put into production it is estimated that it would beat the Ampera’s combined fuel economy of 235mpg and 27g/km CO2 output.
