It can also drive on pure electricity for one mile at speeds of just over 50 mph. Fuel-economy wise, the Panamera S Hybrid currently averages a combined fuel-economy of 34.5 mpg.

Rudolf Krebs, Volkswagen Group chief officer for electric traction, recently confirmed the intentions of the company with regards to the manufacturing of hybrid vehicles, stating that: 'We are really convinced that the future of hybrids won't be pure hybrids, but instead plug-in hybrids.'
