Hybrid technology helps Porsche offer a 168mph super-saloon for the running costs of a diesel family car.

In electric-only mode, the Panamera provides 95bhp and will complete around 20 miles on a charge. If you’re going further though, or want more performance, the 3.0 litre supercharged V6 petrol engine kicks in and offers more grunt and a longer range.

Let the car automatically switch between E-Power, Hybrid, E-Charge and Sport and the Porsche will more often than not achieve the best fuel economy for you, especially if you leave the eight-speed automatic gearbox to its own devices.

This is a Porsche though and will perform like the four-seat 911 you expect from the Panamera.

Fuel economy figures are quoted at 91.1mpg, though in reality will be around half that.

The Panamera retains much of its non-hybrid space inside with a practical boot and plenty of occupant space while build quality stands up to the usual high Porsche standards.

As a plug-in hybrid, you can truly get all the performance of a Porsche but with lower running costs. Since the Panamera was designed as a long distance tourer, adding a hybrid powertrain to increase efficiency and reduce emissions, makes a lot of sense.
