The Porsche Panamera Turbo S is an enhancement of the Panamera Turbo grand tourer. It was introduced in 2011 with the same engine used in Porsche's S version with the difference of a revamped ECU and titanium-alloy turbines. Both upgrades improved the power output of the V8 engine up to 542bhp. The Panamera Turbo S received a facelift in 2014 following the facelift of other variants in 2013.
