The Ohio-based tuners from Switzer Performance have stepped away from taking Nissan GTRs to insane levels of performance, and approached a four-door car for a change. Not just any four-door however, as they decided to see what would the Porsche Panamera turn into after receiving their P680 performance hardware.
So to get to the point, the Switzer P680 Porsche Panamera upgrade program consists of larger turbohargers featuring custom billet compressor wheels along with a new intercooler which makes sure everything runs smoothly at the right temperatures, plus the tuner’s engine optimisation software designed to work properly with the newly added components.
As a result the Switzer P680 Porsche Panamera produces 680 horsepower and 200 lb-ft of torque more than the stock version, and according to Swtizer, the car can now sprint from nought to 60 mph in around 3.5 seconds and from 60 to 130 mph in little over 8.0 seconds.
The Switzer P680 Porsche Panamera can also hit a top speed of 350 Km/h and if you want this upgrade get ready to fork over 22,000 USD.
