Porsche Panamera by Sportec

If you've got your eye on the new Porsche Panamera, chances are it's the performance you're after, because it certainly isn't the looks. And if you want an extra boost, there's no shortage of aftermarket tuning firms that will be glad to dial it up to 11.
The latest is Sportec, a Swiss tuner intimately familiar with customizing Porsches. Its new kit for the Panamera comes in two stages: For $4,600, Sportec will squeeze output up from 493 horsepower and 516 lb-ft of torque stock to an impressive 560 hp and 576 lb-ft, dropping 0.3 seconds off the 0-60 time to run it in a lightning fast 3.9.
Not enough? The stage 2 kit upgrades with a variable exhaust system that raises output even further to 575 hp and 598 lb-ft for a 3.8-second sprint to sixty... and a $12k premium.
