They have a total system output of 500 kW (680 HP) from a 4.0-litre V8 engine (404 kW/550 HP), and an electric motor (100 kW/136 HP) which is integrated into the eight-speed Tiptronic S transmission.
The lovely instantaneous grunt that is such a feature of electric motors means maximum system torque of 900 Nm is available from just above idle.
Both models accelerate from a standing start to 100 km/h in 3.8 seconds and reach a top speed of 295 km/h where conditions permit.
More realistic than that crazy top speed is that they can be driven for up to 40 kilometres with zero emissions. Speeds of up to 135 km/h on just electric power show that Porsche continues to be one of the masters of these new electric machines.
The lithium-ion battery is installed underneath the loadspace floor and has a capacity of 14.1 kWh.
Impressively, the charging process takes six hours from a conventional Australian domestic socket with a rating of 230 volts and 10 amps. Okay, so six hours is a long time, but it’s way better than the 12 to 20 hours we are currently seeing in other cars.
The high-voltage battery can be fully charged within 2.4 hours with the standard 7.2 kW onboard AC charger when using a 400-volt connection with a 16-amp fuse.
Charging can also be scheduled via Porsche Communication Management (PCM) or the Porsche Connect app (for smartphones and Apple Watch).
Connectivity enables online navigation with real-time traffic information, voice control, and extensive Porsche Connect services – including searching for public charging stations. Additional features for all Cayenne derivatives when the new model year starts include wireless Apple CarPlay and new USB-C ports.
These new models are available to order now and will arrive in Australia in December 2019.
The Cayenne Turbo S E-Hybrid is available from $288,000, and the Cayenne Turbo S E-Hybrid Coupé starts at $292,700.
