So, hybrids are supposed to save the world? Well, may as well be quick about it… Porsche’s just-revealed 2018 Panamera Turbo S E-Hybrid combines a 4.0-litre twin-turbo V8 with an electric motor to deliver a ludicrous 680 horsepower and 850Nm of torque for supercar acceleration with 0-100kph dispatched in 3.4 seconds before topping
out at 310kph.

This plug-in hybrid from Leipzig takes the place of the flagship model for the first time in the Panamera line-up, since you’ll notice only the limited-to-918 918 Spyder has ever had more power wearing a Porsche badge and road tyres. What’s even more crazy is that according to Porsche’s release, the Turbo S E-Hybrid average fuel consumption is 2.9 litres per 100km. If you’ve got it charged up, it’ll do 50km on zero-emissions electric power only.

With a boost mode derived from the 918 hypercar, the halo Panamera combines the 550bhp V8 with a motor worth over 130bhp and the same eight-speed double-clutch transmission that serves non-hybrid Panameras does duty here. The PDK ’box sends power to all four corners.

Provided you go for the optional 7.2kW on-board charger, the Turbo S E-Hybrid will juice up in three hours, with control of the process available on the Porsche Connect app. Handily for climates like ours, the car comes with auxiliary air conditioning to cool the cabin before you set off.

With the added weight of the motor and lithium-ion batteries, the car rides on air suspension as standard, although customers do get to choose between the regular or long-wheelbase Executive model also making its debut at the Geneva motor show. The Executive version is 5.9in longer with the extra real estate afforded to rear passengers.

Whichever you choose, all Panamera Turbo S E-Hybrids get carbon ceramic brakes and Porsche Dynamic Chassis Control Sport with torque vectoring included. However, only the Executive comes equipped as standard with rear-axle steering such as you get on the latest 911 Turbos.
