Porsche’s plush 2018 Panamera 4 E-Hybrid plug-in, one of two gasoline plug-in hybrid electric vehicles (PHEV) planned to join the new Panamera line, made its debut at the Paris Motor Show.
The Panamera was the German performance automaker’s first four-door sedan when it debuted in 2009, and was a polarizing entry that was met with either a love or hate response, but proved to be successful.

Deliveries of the Panamera S-E-Hybrid plug-in began in the U.S. in 2013 and it wasn’t Porsche’s best example of engineering, as shown by sales of just 1,511 through the end of August.

Set to arrive in the middle of 2017, the all-new 2018 Panamera 4 E-Hybrid plug-in erases the deficiencies of the outgoing model.

For example, it turns in some pretty impressive performance numbers: Total-system power of 462 horsepower, pavement-powdering twist of 516 pounds-feet of total-system torque, zero-to-60 mph sprints in the mid 4’s and a top speed of 172 mph.

All that eco-friendly hybrid churn is channeled to all four wheels through an eight-speed dual-clutch automatic transmission.

However, should the driver on a given trip prefer frugality to fury, this plug-in hybrid is said to provide an electric-power-only range of up to 31 miles.

That’s based on the overly generous New European Driving Cycle (NEDC) rated range, a U.S. EPA number has not been given, but might be around 20 20 miles, compared to 15 mpg for the outgoing 2016 S E-Hybrid..

Under the coupe-like four-door’s lithe sheetmetal is a 2.9-liter 330 horsepower twin-turbo V-6 borrowed from Audi.

That’s aided and abetted by a 136 horsepower electric motor and a liquid-cooled 14.1-kilowatt-hour lithium-ion battery pack — up from a 9.4 kWh pack in the previous Panamera plug-in hybrid.

That combination can motivate the new Panamera plug-in via the primary electric-assist hybrid mode or with electric-only power.

Unlike its predecessor, which required its accelerator to be at 80 percent to engage the electric motor in what Porsche called E-Boost, the 2018 model can unleash all of the electric output at any time.

The battery can be charged in 5.8 hours using a standard 3.6 kW charger, while an optional 7.2 kW charger reduces the charging time to 3.6 hours.

There are two modes that save drivers the trouble of plugging in to recharge the batteries.

The E-Hold setting keeps the charge roughly at a constant level, and E-Charge conveniently but somewhat inefficiently uses the gasoline engine to recharge the battery pack.

To let bystanders know you are a tree hugging Porsche lover, the Panamera 4 E-Hybrid features exterior green badges and, egads, green brake calipers.

As usual for a new car introduction, pricing for the 2018 Panamera 4 E-Hybrid was not released, but a beginning sticker price could be around $110,000.
