There are plenty of tuners ready to sell you a tweaked Porsche Cayenne. Techart has done just that for years, and now the latest Cayenne is ready for the company's Magnum treatment. This goes way beyond the aero kit we saw last year. There are vents upon vents, bold wheel arches, carbon fiber to spare, and up to 930 horsepower under the hood. Say hello to the new Techart Magnum.
