Frugal Luxury: 2004 Porsche Cayenne S with 1.9 TDI Diesel.
A 2004 Porsche Cayenne S has been modified with a 1.9-liter TDI diesel engine from Volkswagen, producing 150 horsepower and paired with a six-speed manual gearbox. The owner claims that the SUV is now at least twice as efficient as before, while still retaining much of its performance on the highway. The Cayenne's original infotainment system has been replaced with a 10-inch touchscreen display running Android, but the LED lights integrated into the OEM reflector halogen lights at the front have received mixed reviews.
