Daimler, the parent company of Mercedes-Benz, is making all top managers drive either hybrid or electric vehicles going forward.

According to an article in Fortune, the company says this new policy is meant to help set a good example.

In addition, Daimler announced it will invest $33 million to upgrade its charging infrastructure at various offices and facilities. The company already has installed 556 charge points in its hometown of Stuttgart.

The new policy will only apply to senior managers. Initially, their will be a focus on plug-in hybrid vehicles like the S 500 e, C 350 e Saloon, GLE 500 e 4MATIC,  GLE 350 e 4MATIC, and the E-Class 350 e. Managers will be able to choose from any of those vehicles.

Daimler foreshadowed this new policy by using a pilot program in which managers drove B-Class 250 e vehicles around Stuttgart. The program started last April, and the B-Class 250 e is a pure EV.

Lower staffers won’t be required to drive these types of cars, but the company will make more available to them. A two-year-old program named [email protected] offers EVs to employees for work and personal use.

There’s more to this than setting a good example: Mercedes-Benz has plans to announce 10 new plug-in hybrid models by 2017. That doesn’t mean that the make is giving up on diesel – just this month, the brand took the wraps off of its next generation of diesel engines, which will work their way into the lineup from March until the 2019 model year.
