At the New York Auto Show Porsche just pulled the wrappers off the world’s fastest production sedan, the new 2012 Panamera Turbo S.

The $173,000 four-door supercar features a 550 hp twin-turbocharged 4.8-liter V8 engine good for a 0 – 60 mph sprint of 3.6 seconds and a top speed of 190 mph.

For the more economically-minded the company also unveiled the new Panamera S Hybrid, which while not quite as fast uses a lot less fuel.

Decisions, decisions….
