As with other TECHART products, the Magnum has added features such as a bodykit, interior refitment, and engine and suspension upgrades.

To the standard Porsche Cayenne turbo, TechArt has added a radical bodykit made of PUR-RIM plastic, which includes new high-downforce air dams, side skirts, and aero hood.

The stock 4.5L (274.6 cu in) V8 turbo has been modified with larger turbochargers, stainless steel exhaust, and an upgraded ECU chip, bringing output to 600 horsepower (447 kW) and 645 lb⋅ft (875 N⋅m) of torque, both at 3440 rpm.

The Magnum is also lowered up to 30 millimetres (1.2 in) with adjustable performance air-ride suspension, which greatly aids handling for the heavy vehicle.
