Porsche unveiled the first GTS version of the 911 Carrera sports car in 2010. Based on the 997-generation Carrera, the GTS slotted between the regular Carrera models and the track-ready GT3 in terms of output, being launched with an upgraded 3.8-liter flat-six engine that cranked out 408 horsepower. Initially a rear-wheel-drive model only, the GTS gained an AWD version in 2011. The model was discontinued in 2012, when the 997-generation 911 was replaced by the 991. As we move towards the 2015 model year, the GTS returns to bridge the same gap in the 911 range.
