Porsche, looking to lure green enthusiasts who don’t want to compromise power or performance, will use the Paris auto show this month to unveil a Panamera plug-in hybrid that it says will zoom from 0 to 60 mph in just 4.4 seconds.
The first Panamera plug-in hybrid will have plenty of power: 462 hp and 516 pounds-feet of torque, most churned out by a twin-turbocharged 2.9-liter V-6 engine borrowed from Audi. The engine is combined with an eight-speed PDK transmission and standard all-wheel drive.
The 2018 Panamera 4 E-Hybrid features an electric motor with 136 hp and 295 pounds-feet of torque, which is made available as soon as the accelerator pedal is touched, Porsche said.
Previously, the pedal needed to be pressed at least 80 percent of the way down to access the additional power of the electric drive’s E-Boost mode.
Porsche, gunning for a slice of Tesla’s fan base, says the recently redesigned sedan will always start in electric mode and operate as a zero-emission vehicle with a maximum all-electric range of 31 miles and a maximum speed on battery power of 86 mph.
The electric motor is powered by a liquid-cooled, lithium ion battery that can be fully charged in 12 hours via a common, 120-volt, 10-amp connection, Porsche said. When the optional 7.2 kW on-board charger is used, charging time is less than three hours with a 240-volt, 40-amp connection.
Inside is a power meter similar to that in the 918 Spyder, which lets the driver know how much electrical energy is being used and how much is recovered through recuperation.
The Panamera 4 E-Hybrid has four hybrid-specific driving modes:
1. E-Power puts the powertrain in pure electric mode.
2. Hybrid Auto adjusts and combines the internal combustion and electric mode drive sources automatically for efficiency.
3. E-Hold lets a driver conserve the battery’s current state of charge, which allows the driver to “utilize electric mode in an environmental zone at their destination,” Porsche said.
4. E-Charge uses the engine to charge the battery by generating more power than is needed for driving.
The 2018 Panamera 4 E-Hybrid is expected to arrive in the U.S. by summer 2017. Pricing will be announced later, Porsche said.
