Porsche 911 Turbo S Convertible
barely. In reality, the overall performance associated with open-top Turbos is more impressive than ever before. In non-S trim, the twin-turbocharged flat-six tends to make 520 horse power from 6000 to 6500 rpm; optimum torque is 487 lb-ft, offered by 1900 to 5000 rpm. Top rate is 195 miles per hour, and sprint from standstill to 60 miles per hour, Porsche states, takes 3.3 seconds—or 3.1 moments if the recreation Chrono bundle is specified. The Turbo S raises the bar even further, using horsepower up to 560 and torque to 553 lb-ft. The results, if Porsche’s estimates can be thought, are on the impressive side: a level three seconds to 60 and a top speed of 197 mph. Despite these types of gaudy numbers, Porsche claims that both models will get EPA ranks of 17 mpg in the town and 24 on the road.
The liquid-cooled twin-turbo 3.8-liter is direct-injected, and it features four overhead camshafts and an adjustable valve-lift system. Its short-stroke design permits a lofty 7000-rpm redline, which is raised an additional 200 rpm in the Turbo S. A working all-wheel-drive system really helps to place the awesome power to the floor, with the help of a locking differential and a torque-vectoring system. More enhancing overall performance is a rear-wheel-steering system that "has an immensely positive impact on managing, " states Porsche, and energetic aerodynamics. In coupe kind, the rear-wheel-steer function had been nearly imperceptible save for the eerie sense of a shifting across the central axis, whilst the powertrain had been, well, eyeball-squishingly quickly.
