The high-output plug-in hybrid features a 4.0-litre twin-turbo petrol V8 assisted by electric motors for a combined 500kW of power and 850Nm of torque.
All that performance isn't enough to put a dent in the Turbo S E-Hybrid’s green credentials though, with an official 3.0L/100km fuel consumption rating.
Porsche also claims the hybrid wagon can do the 0-100km/h sprint in just 3.4secs, and under less demanding driving circumstances can cover up to 49 kilometres using electric power alone.
However, the combination of speed and frugality comes at a price, with the Panamera Sport Turismo Turbo S E-Hybrid priced from $466,400 plus on-road costs, making it $75,700 more expensive than the Sports Turismo Turbo and a huge $200,000 pricier than the V6-engined E-Hybrid.
For the asking price, Porsche includes Porsche Dynamic Chassis Control (PDCC Sport) roll stabilisation including the Porsche Torque Vectoring Plus (PTV Plus) rear differential lock, high-performance Porsche ceramic composite braking system (PCCB), 21-inch alloy wheels, Sport Chrono Package and three-chamber air suspension including Porsche Active Suspension Management (PASM).
The Turbo S E-Hybrid tops the Sport Turismo range, sitting above the Turbo ($390,700), diesel-powered 4S ($325,900), V6 4 E-Hybrid ($255,800) and 3.0-litre V6 petrol entry-level model ($232,500).
