Porsche 911 Turbo Cabriolet
Each generation of Porsche 911 Turbo has held up the claim of being a global benchmark for high-performance sports cars. It has maintained this reputation since 1975 by continually honing a combination of exhilarating performance and everyday usability, delivering relentless power coupled with conscientious efficiency. The latest generation of the two-plus-two seater is more than twice as powerful as the original 911 Turbo, which was powered by a three-litre, single-turbocharged, 260 PS flat-six engine. As the Porsche 911 Turbo has become faster and more comfortable over the past 45 years, it has always stayed true to its original defining character - a compelling mix of pioneering spirit and tradition.
The new generation Porsche 911 Turbo Coupé and Cabriolet sit beneath the flagship 911 Turbo S. With a 580 PS version of the characteristic flat-six, twin-turbo engines, the Porsche 911 Turbo offers 40 PS more than the prior generation model and consequently is able to dip under the three second 0-62 mph yardstick; specifically in 2.8 seconds (0.2 seconds quicker than before). This is aided by 750 Nm of low rev pull (+ 40 Nm), now without an overboost time limit, that makes quick sprints more spontaneous and effortless. In this way, the metrics for power output, acceleration and torque of the new 911 Turbo match those of the previous model 911 Turbo S.
The 3,745 cc six-cylinder flat 'boxer' engine in the Porsche 911 Turbo now features symmetrical VTG turbochargers with electrically controlled wastegate bypass valves. The VTG system adjusts the intake boost according to engine speed and load. Being mounted in a symmetrical layout, means the turbocharger compressor and turbine wheels now rotate in opposite directions. In conjunction with its redesigned charge air cooling system and the use of highly accurate piezo fuel injectors, these developments help improve throttle responsiveness, torque characteristics and let the engine rev more freely.
