Restrictions and regulations are making it harder for manufacturers to produce high-performance vehicles. Manufacturers now have to balance performance, as well as efficiency, even in their sport models. Porsche has taken the hybrid power route and has been doing so since 2010 but the automaker has now added even more power to their hybrid systems with their latest reveal.

Geneva 2017: Porsche Panamera Turbo gets hybrid boost

Last year, the Stuttgart-based automaker unveiled the Panamera 4 E-Hybrid, which featured a twin-turbo V6 and an electric motor working together to produce 462 PS and 700Nm of torque. Now, the most powerful Panamera will make its debut at the Geneva Motor Show next month.

Called the Panamera Turbo S E-Hybrid, it will be available in two body styles, namely standard and Executive. In Porsche-speak, the Executive body style is the long wheelbase version of the Panamera, adding 150 mm in the space between the wheels. It keeps its green credentials hidden as well with only a green Panamera Turbo S badge being the only hint from the outside.

Being the most powerful variant, the Panamera Turbo S E-Hybrid is powered by a 4.0-liter twin-turbo V8, mated to a 14.1 kilowatt lithium-ion battery pack. The result is 550 PS from the gas engine and 136 from the electric motor. Combined, it can make 680 horsepower and 849Nm of torque. Charging the battery takes 12 hours on a 120volt 10amp plug, but only takes less than 3 hours if used on a 240volt, 40amp socket.

To put the power down, a 8-speed PDK dual-clutch gearbox comes standard along with all-wheel drive. Other features include air suspension, ceramic composite brakes and Porsche's Torque Vectoring Plus system.
