Porsche announced details of the 2014 Panamera lineup in the United States. The entry-level model in America is the Panamera 4S, and the range-topping the Panamera Turbo. Bang in the middle sits the Panamera S E-Hybrid, the first plug-in hybrid from Porsche.

The new 2014 Porsche Panamera comes with significant changes over the previous model. Apart from the visual subtle visual changes, the car’s technicalities have been the subject of an overhaul. Gone is the old 4.8 liter V8 engine in the S models, and it’s replaced with a 3.0 twin-turbo V6. Not to worry though, as the new V6 gives you access to 20 more horsepower and 15 lb.-ft. of additional torque, with an increase of up to 17 percent in fuel economy compared to the V8 engine. So it’s all good in the hood.

On the other side of the scale we have the 2014 Porsche Panamera Turbo. This is still a beast of a car, powered by a massive 520 hp V8 engine. It goes from zero to 60 mph in just 3.7 seconds, and can reach 189 mph. The new model’s fuel economy is improved up to 24 mpg highway. The 2014 Porsche Panamera 4S and Turbo get the Executive trim with standard adaptive air-suspension featuring Porsche Active Suspension Management (PASM).

The most interesting Panamera model, from a technical point of view, is the S E-Hybrid. Thank to a 95 hp electric motor that is attached to its internal combustion engine, the Panamera S E-Hybrid can go from 0 to 60 mph in 5.2 seconds and reach 167 mph flat out. But if you still want a naturally aspirated V8 engine, you have to wait for the Panamera GTS. With 440 hp the new GTS accelerates from zero to 60 mph one tenth of a second faster (4.2 seconds) than the previosu model.
