While Porsche fans welcoming new technology like the direct-injection and the dual-clutch gearboxes that help improve fuel-economy, Porsche customers aren't liking the all-new “Start-and-Stop” system.
Talking with Porsche engineers at the press launch of the 2009 911, sources learned that while a Start-Stop system was considered for the facelifted model, the sports manufacturer clientele put a brake on the use of such a system.
The company’s engineers told reporters that if they had fitted the facelifted 911 with a BMW-style start-stop system, it would have reduced a further 10g/km of CO2 from the 911's 225g/km CO2 emissions.
Apparently, Porsche fans will take all the green technology the German firm can offer them as long it also improves performance and/or dynamics.
