Targa shoppers get to choose between two powertrains, the 325-horsepower, 3.6-liter six-cylinder engine in the 911 Targa 4 or the 355-horsepower 3.8-liter "boxer" six in the 911 Targa 4S. Performance-wise, you can count on 0-62 mph in 5.3 seconds in the Targa 4, and just 4.9 in the Targa 4S. Both Targas come with the full array of Porsche technologies, such as Active Suspension Management technology (optional on the Targa 4), Porsche Stability Management and advanced braking systems.
