When a car is expensive and powerful, sometimes it's a good idea for it to be subtle as well. Take this Porsche Panamera Turbo given the once-over by Mansory, that Swiss tuning house of repute. Now it has 36 percent more power than stock, the numbers being 680 hp and 516 lb-ft of torque going to an all-wheel drive system. The sprint to 60 mph is quicker by two-tenths of a second (now four seconds dead) and top speed goes from 188 to 203 mph. This muscle hike has been achieved by adding bigger turbochargers, an ECU re-flash, and improved breathing courtesy of a custom sport exhaust. Then Mansory installed a body kit for better aerodynamics and a carbon-fiber hood, plus a re-upholstered blue-and-yellow interior with a new steering wheel. Subtle? Like a brick to the groin.
