At present, the standard model is available in two versions. There is a normal trim and there is the Executive extended version that was made specifically for the Chinese market. The plug-in hybrid system is composed of the twin-turbocharged 2.6-liter V6 engine and an electric motor. The electric motor can deliver 134 hp (100 kW) with the V6 engine being able to offer an output of 330 hp (243 kW). This results in around 462 hp (340 kW) of power and is complemented with maximum torque of 516 lb.-ft. (700 Nm).
Reports though are saying that if the brand does come out with a performance model, it is expected to have power of at least 500 hp (373 kW) and thus allow it to have maximum speed of at least 180 mph (289 km/h). If true, this will make it the second fastest Panamera right behind the Panamera Turbo. Various reports also say that this performance model will likely be unveiled at the same time as Porsche will reveal the Panamera Sport Turismo shooting brake, which is next month.
While the power is indeed impressive, the 2.9-liter engine of the Panamera 4S is used rather than the V6 unit. Its 434 hp (323 kW) output would mean a total combined output for the hybrid system of at least 560 hp (417 kW).
This is not likely to happen though according to Stefan Utsch, Panamera sales and marketing director. He explained that it would be possible for the electric motor and the internal combustion engine to be able to deliver maximum output simultaneously. Thus, maximum output could well be less than 560 hp.
It is tentatively named as the Panamera 4S E-Hybrid. If the specifications are followed, it would be able to go from 0 to 62 mph (100 km/h) in 3.4 seconds. This may not be much given the power but there is a chance that the performance will be affected by the total weight as an extra 551 lbs. (250 kg) have been added.
With the latest Panamera 4 E-Hybrid Executive version, the current Panamera lineup has a total of 10 models. Priced in the U.S. at $104,100, the Executive version retains its sleekness while having a more imposing appearance due to the wheelbase being longer.
Compared to the standard version, the Executive trim has a wheel base measuring 122 in. (3,100 mm), an increase of 5.9 inches (150 mm). Like many of the Executive versions previously released by the brand under the 4, 4S, and the Turbo, this one also has a number of exceptional features like the damper system which is controlled electronically and the adaptive air suspension. It also has a roll-up sunblind, electric and heated seats, and of course, the panoramic roof.
