(June 17, 2010) — The 2011 Panamera and Panamera 4 featuring the company’s all-new, fuel efficient 300-horsepower V6 engine will began arriving last week at Porsche’s nearly 200 dealerships across America.

These new models come just eight months after the successful launch of the V8-powered Panamera S, Panamera 4S and Panamera Turbo. Since then, Porsche has sold more than 4,000 Panamera Gran Turismos to U.S. customers.

The new Panamera models feature an all-new, Porsche-designed 3.6-liter, 90-degree V6 engine with Direct Fuel Injection (DFI) that develops 300 horsepower and 295 lb-ft of torque. Built on the same line as the normally aspirated and twin-turbocharged 4.8-liter V8 engines found in the Panamera S, 4S and Turbo, this new engine propels the Panamera and Panamera 4 from 0 to 60 mph in 6.0 and 5.8 seconds, respectively (5.8 and 5.6 seconds with the Sport Chrono Package Plus option). Top test track speeds are 160 and 159 mph, respectively.

As a whole, these new models provide high levels of performance, agility and comfort and the same safety systems found in the V8 Panameras, yet they return even better fuel economy figures than the already efficient Panamera S, 4S and Turbo. The Panamera achieves 18 mpg city/27 highway while the all-wheel-drive Panamera 4 delivers 18 mpg city/26 highway, numbers that are no doubt appealing to consumers who demand driving excitement and fuel efficiency.

The Panamera and Panamera 4 MSRPs are $74,400 and $78,900, excluding destination.
