Porsche is introducing its first plug-in hybrid and two new extended wheelbase variants with the second generation of the Panamera. The new Panamera S E-Hybrid produces 416 total system horsepower (310 kW) and is joined by Panamera 4S Executive and Panamera Turbo Executive models in the revised Panamera lineup.

The new Panamera S E-Hybrid improves upon the hybrid powertrain offered by the previous Panamera S Hybrid (earlier post)—which is not listed in the new generation Panamera line-up—with a more powerful electric motor, and a higher-performance battery that supplies more energy and is able to be recharged from home or public vehicle charging stations.

The electric drive produces 95 hp (71 kW), more than double the power of the previous model’s electric motor (47 hp, 35 kW). Electricity is stored in a newly developed lithium-ion battery, which at 9.4 kWh has increased capacity over the previous battery (1.7 kWh).

Via the integrated on-board charging componentry and the standard Porsche Universal Charger (AC), the battery can reach full charge within approximately two and a half hours when connected to a 240V power source.

The Panamera S E-Hybrid expands upon the driving performance of the previous generation, while fuel consumption is reduced when compared to the previous Panamera S Hybrid. Final US EPA fuel economy ratings will be available closer to launch.

Simultaneously, its electric-only driving performance is substantially improved, enhancing acceleration, range, and top speed. The electric driving range of the Panamera S E-Hybrid is estimated to be greater than 20 miles (32 km) based upon current NEDC testing. Driving range may vary in real world operation, due to the effects of environmental conditions, terrain, air conditioning and heating use, driving style and other factors. The Panamera S E-Hybrid can reach up to 84 mph (135 km/h) in all-electric operation.

The Panamera S E-hybrid is capable of accelerating from a standstill to 60 mph in 5.2 seconds, an improvement of a half second when compared to the Panamera S Hybrid. An electric boost function helps in instances where maximum acceleration is desired, when the electric motor works in tandem with the combustion engine during acceleration. Electric boost is also available when a kick-down switch in the throttle pedal is activated by the driver during acceleration.

The car’s top track speed is 167 mph (269 km/h). The parallel full hybrid system developed by Porsche also offers “coasting” at higher speeds, a mode in which the internal combustion engine is turned off and the electric motors use vehicle momentum to generate electricity that is stored in the lithium-ion battery.

The Panamera S E-Hybrid also includes an entirely new range of convenience functions which can be activated and operated by Porsche Car Connect, a mobile app available for Android and iOS-powered devices. These functions include a charge status indicator and the ability to control the vehicle's new auxiliary climate control option, which enables vehicle preheating or cooling via the Porsche Car Connect app. These functions can also be programmed from inside the vehicle. A mobile device may also be used for remote access to vehicle information, such as remaining driving range or vehicle location.

New twin-turbo V6 engine. S models are now powered by an entirely new 3.0-liter V6 engine with twin turbochargers. The twin-turbo V6 replaces the naturally aspirated 4.8-liter V8 engine in the previous-generation Panamera S and Panamera 4S. The new bi-turbo engine is also used in the Executive version of the Panamera 4S. The engine offers increases of 20 hp and 15 lb-ft torque when compared to the outgoing V8 engine. Carefully-managed turbocharging ensures that the maximum 384 lb-ft (521 N·m) torque is available across most of the twin-turbo V6’s operating range.

Transmissions. With the exception of the Panamera S E-Hybrid, all Panamera models are equipped with the seven-speed Porsche Doppelkupplungsgetriebe (PDK); the Panamera S E-Hybrid uses the eight-speed Tiptronic S automatic.

The PDK transmission works in tandem with other vehicle systems to enhance fuel savings in the new generation Panamera. For example, the optimized engine Auto Start Stop feature now turns the engine off earlier while coasting to a stop. With the exception of the Panamera GTS, models with PDK also offer a coasting function in which the clutches open in overrun allowing the engine to idle and the vehicle to coast freely. This function can significantly improve fuel economy, especially when traveling on the highway.

Assistance systems. An expanded lineup of assistance systems is available. The revised adaptive cruise control system is now offered with Porsche Active Safe (PAS). This system visually and audibly alerts the driver in the event of a sudden decrease in following distance and briefly tugs on the brakes. It can also intervene in the braking process and apply increased braking pressure in an emergency braking situation, if required. Another new feature, camera-based lane departure warning, offers greater convenience and safety in city and highway travel.

The refreshed Panamera will celebrate its world debut at Auto China in Shanghai, which opens on 21 April, where further details on the new models will be revealed. The new generation of Panamera models will be available starting late in 2013. Panamera Turbo S and Panamera Turbo S Executive variants will be available in 2014. The Panamera S will start at US$93,200, while the plug-in Panamera S E-Hybrid starts at $99,000.

@ Roger : Please whatch this video :

Battery is only 48KWH, but 10C makes 480KW instant power, unfortunatly no Range Extender yet..., but a real dream in terms of all electric intelligent drive train with 1 x electric motor per weel. Batteries are Huge but would llok smaller in a luxury SUV formfactor. May be pre-figuring a Better than Tesla, but Tesla inspired, European PHEV... Just need to add a range extender to make it a real car. I would be fine with a 35KWH version if same 10C means 350KW with a Range extender in an luxury SUV formfactor if sold < €60K = $90K budget next year for ex.

Thanks, Patrick for the link. Watching this video is like escaping to 18 minutes of automotive heaven.

The potential to improve on this car's performance is quite vast. This battery is from Korea, and perhaps the technology is already quite dated. The battery weight was announced to be 550kg. With 48kWh, that works out about 81 Wh/kg, and at only 10 C discharge rate, the power density is very conservative.

Modern LiPo battery from China now has 150Wh/kg, almost twice as much energy density, while entry level LiPo now is at 25C constant discharge rate and 50 C burst rate. Charging rate is up to 8C, allowing one to charge the battery from 20% to 80% in 6 minutes. Imagine that, now MB can reduce the battery pack weight down to under 1/4 th of the 550 kg of battery weight and still have the same power rating! Using modern LiPo, the battery weight will be down to 130 kg, for a saving of 420 kg, or 924 lbs of weight saved. Just imagine what this weight reduction will do to the vehicle's acceleration, handling, and range?

Stay tuned, more exciting stuffs to come!
