Porsche GT2RS

Power-to-Weight Ratio: 620 hp / 3,020 lbs = .205 0-60 mph: 3.4 seconds Top Speed: 205 mph Take your standard 911 Turbo, rip out the back seats and every other piece of material non-integral to going like stink, crank the turbo pressure up to 11, add a bit of maniacal German magic and you get the Porsche GT2 RS. Oh, did I forget to mention they also dumped the Turbo’s AWD as well? Yes. Yes, they did. Dubbed “The Widowmaker,” the GT2RS is the most nutso, bonkers, insanely quick Porsche in production. Cranking out 620 hp and 516 lb-ft of torque, this nuclear-powered ballerina weighs just north of 3,000 pounds and is purpose-built to cut corners with surgical precision and then cauterize its exit with the searing, force-fed induction of its 3.6-liter flat six.
