The current line up of Panamera is topped by the Panamera Turbo, AWD Panamera, Panamera S, and the standard variant Panamera. All run on a V8 4.8 L which can be turbocharged or naturally aspirated.

By 2010, Porsche will release to the market the V6 entry level model and the hybrid Panamera which runs on petrol-electric systems. There is also a possibility for a Cabrio two-door model.

The hybrid Panamera will team up with the current SUV prototype Cayenne in answering the market’s need for a more environment-friendly Porsche. The Panamera Cabrio is also in the works. The Cabrio will be released with a V8 and V6 variants.

Porsche is also coordinating with a Volkswagen group to come up with a diesel version. Porsche execs have commented that there are bases that they can use to develop a diesel Panamera with a V8 or V6 engine. That car may use a V8 similar to the Audi A8 which outputs 322hp and the V6 of the Cayenne which generates 240hp.

The Panamera GTS will use the Turbo platform of the Panamera sedan but will use steel springs instead of the air suspension.

According to the Stuttgart, Germany-based manufacturer, the Panamera is built for total performance and maximum efficiency. The designers boast of Panamera as the first car with an automatic double clutch transmission that is coupled with an engine that has a Start/Stop system.

The start/stop system adds to the fuel efficiency of the Panamera as it turns off the engine when its power is not needed, like when waiting for a green light. Aside from this benefit, the technology also helps in lowering its emissions.

The engine of the Porsche Panamera is also equipped with the very efficient Direct Fuel Injection technology. All Porsche Panamera due for release in the United States in October 2009 comes with a PDK gearbox which makes it more fuel efficient.

The wheels of the Panamera are also designed to have lesser rolling resistance. The brakes are also engineered to have minimum residual brake forces.

The Panamera only uses up 10.8 L of fuel for every 100 kilometers or 26 mpg imp. That’s not AWESOME fuel efficiency, but that’s good for a Porsche.

The car on its Panamer Turbo release comes with a rear spoiler that is adjustable in a multi-stage setting. The four-way spoiler is activated depending on the driving condition and employs excellent surface geometry and precision control of the angles.

The body of the Panamera consists of different steel grades, alloys like magnesium and aluminum, and plastics. This ideal architecture gives the Panamera S only weighs around 1800 kilograms.
