Developing a car like the new 911 GT3 presents a fundamental engineering challenge. While the primary objectives are technological excellence and superlative race performance, the car is required to deliver this capability within strict environmental parameters. Key objectives in this respect include better fuel economy, lower emissions, economical servicing, lower noise and optimum recyclability of materials. Added to these is another traditional Porsche quality: the ultimate longevity of the car itself. After all, a longer service life represents the best possible use of resources.
