• The effect of an additional 300 pounds - 2017 Porsche 911 (991.2) Targa 4 test numbers

      300 pounds is a lot of weight. Think of it this way, this 2017 Porsche 911 Targa 4 is hauling around an extra refridgerator compared to a standard rear wheel drive Porsche 911 Carrera.

      It shows in the performance metrics. The PDK 3614 pound Targa 4 gets through the 1/4 mile in 12.1 seconds at 115 miles per hour.

      How does this compare to a standard 911 Carrera? The PDK C2 runs 11.8 @ 118 in the 1/4 mile. Essentially, exactly 3/10's and 3 miles per hour off due to the 300 pound weight difference.

      The Targa models are the heaviest in the lineup partially because they come standard with all wheel drive. Most buyers likely do not care. The Targa does offer a beautiful open air experience with unique styling.

      If you are into performance and the driving experience above all else, get the rear wheel drive coupe. If you want a hardtop convertible, get the Targa.

      Car and Driver sums it up well:

The extra weight, combined with the base 19-inch wheels and Yokohama Advan Sport tires, resulted in this car turning in the lowest cornering performance of the latest 911s we’ve tested, at 0.99 g—the only 991.2 to fall short of the 1.00-g threshold. This car also displayed more understeer and generally didn’t drive as playfully as other 911s we’ve tested recently. And the structural rigidity of the Targa is palpably less solid as well. With the top up, sharp impacts reverberate up through the open rear area, and, at low speeds between the whistling of the turbos spooling up, we noticed some creaking emanating from the top itself.

      We’re torn: We love the way the Targa looks but wish it didn’t come along with the extra heft and weakened structure that dulls the 911 experience. Choices, choices.

        It is beautiful. Bummer that the weight is so much worse though.

        For manual guys or gals without sunroof, that would be 500 lbs.

        Nice color btw ;-)
