Mercedes-Benz will be highlighting some of its greenest ever cars at Company Car in Action, three months after taking a hat-trick of Fleet News Awards.

Diesel-electric hybrid models, a plug-in petrol hybrid, a battery electric vehicle, and alternative fuel powertrains will take their place alongside efficient conventional engine variants as well as a new line-up of compact Smart cars at the event in Millbrook.

Mercedes-Benz launched the latest version of the C-Class saloon and estate in 2014, and while the lowest CO2 from a conventional diesel version is 101g/km, the C-Class is also available as a diesel-electric hybrid with CO2 emissions from 94g/km.

The S-Class range gained an ultra-low CO2 variant in 2014, when Mercedes-Benz added a plug-in petrol-electric hybrid powertrain. This model, which has CO2 emissions of 65g/km and qualifies for a 100% discount on the London congestion charge, will also be available to drive at company car in action.

Sally Dennis, head of fleet at Mercedes-Benz, said: “Mercedes-Benz will showcase a variety of vehicles across the range to highlight our dedication to meeting diverse fleet customer requirements, and to satisfy the ever increasing demand for class-leading green credentials.

“Vehicles available to test drive include the C-Class – recently named World Car of the Year 2015 with CO2 emissions from 94 g/km, the S 500 Plug-in Hybrid with CO2 emissions from as low as 65 g/km, the zero-emission B-Class Electric Drive – released earlier this year – and the Smart Forfour.”

While all of those vehicles have variants with CO2 emissions below 100g/km, attendees will also have the opportunity of a high-performance accompanied ride in a car with CO2 emissions of 219g/km – although perhaps modest given the vehicle’s performance.

The Mercedes-AMG GT coupé is currently used at the official safety car in the Formula One World Championship, and according to Mercedes-Benz, along with other AMG variants at Company Car in Action, Mercedes-Benz helps illustrate the breadth of the range and ability of its models.

Company Car in Action is held at Millbrook Proving Ground, in Bedfordshire, and vehicles are available to drive on one or more of four circuits purpose built for appraising road vehicles.
