While the 2010 Porsche 911 Turbo receives a number of small visual tweaks first launched on the 2009 911, the biggest news is what lies underneath the (rear) hood. The new 911 Turbo ditches the 3.6-liter mill found in the outgoing car, and moves to a direct-injection, twin-turbocharged 3.8-liter flat-six. Porsche says the new engine pumps out 500 hp (20 hp more than before), all while improving both fuel economy and CO2 emissions. If buyers opt for the Sport Chrono package, torque output is increased to 516 lb-ft from the meager 500 lb-ft a base 911 Turbo makes do with. Another reason to order the Sport Chrono package is the dynamic engine mounts that use magnetic fluid to stiffen during hard driving.
