The 4S has a more powerful version of the 2.9-liter V6, producing 443 hp and 405 lb-ft of torque. While it makes the Panamera faster, you have to pay extra for the Sport Chrono Package, which adds launch control. The interior specification is the same as the 4, but the 4S has titanium grey brake calipers and quad exhaust pipes. While the 4S is not as fast to 60 mph as the Audi RS6 Avant, it is faster at the top end. That’s only because the Audi is limited, however.
