2018 Porsche Panamera Sport Turismo models will be available with the four engines launching with the sports sedan, and they consequently maintain the same 0 to 60 acceleration figures. The Panamera 4 Sport Turismo is powered by a 3.0 liter turbocharged V6 generating 330 hp, and it will accelerate from 0 to 60 mph in 5.0 seconds with launch control. The Panamera 4S Sport Turismo reaches 60 mph (with launch control) in 4.0 seconds and is powered by a 2.9 liter twin-turbocharged V6 engine.
2018 Porsche Panamera 4 E-Hybrid Sport Turismo is powered by the same combustion engine as in the 4S, and it has an additional 136 hp electric motor which in combination propel it from 0 to 60 in 4.4 seconds.
The total system power is achieved by combining the 243 kW (330 hp) output of the 2.9-litre twin-turbo V6 engine with the 100 kW (136 hp) output of the electric machine. But a high-performance electric machine also needs a powerful energy store – and this task is handled by the 14 kWh lithium-ion high-voltage battery. As a result, the vehicle boasts an electric range of 25–51 km. And a top speed of 140 km/h on electric power alone.
