Interesting first drive review here of the new Porsche Panamera GTS.
Tactile differences between the GTS and a similarly optioned 4S are few. The biggest change (and perhaps the best reason to choose the GTS) is the sound. While a dual-mode sport-exhaust system is offered for the Panamera 4S, this one is more aggressive. It’s subdued in regular mode but masterfully antisocial in “sport.” The GTS fires up with an Italianate bark and bellows through the gears, punctuating shifts with gruff coughs and cantankerous burbles. A resonator pipes sound from the intake manifold into the A-pillars, balancing the exhaust snarl with precombustion music. After driving in “sport” for most of a day, we switched the exhaust to its quieter setting and immediately felt guilty, as though we’d muted Charlie Parker’s sax with a fat partridge.
