If you visit the Volvo website you will discover the following statement:

“In 2017 we made a commitment to electrify every car in our range in preparation for an era beyond the internal combustion engine. That era begins now. Be a part of this change. We’ve been working with electric propulsion since the 1970s and we have learned a lot along the way, from deploying a test fleet of C30 Battery Electric Vehicles in 2010, to the launch one of the world’s first plug-in hybrid diesel cars in 2012.”
