When A 500HP Porsche GT3 RS Is Not Enough: Meet The 700 HP $293,000 Porsche GT2 RS
Measurables are a good place to start with the most powerful street-legal Porsche 911 ever. GT2 RS’s 3.8-liter twin-turbo flat-six is an evolution of the current 911 Turbo S motor I sampled on the drive home from Pebble Beach last year. Thanks primarily to much larger turbos delivering significantly more boost, in GT2 RS form the engine develops an additional 120 horsepower, for a total of 700. That’s roughly equal to the power of the most radical 911 racecars of all time, the 935s of the late 1970s and ‘80s, which at their peak made a touch more than 700 hp, but those engines were good for 24 hours and a few minutes extra for a victory lap. GT2 RS is completely road legal, having passed the sniff test with the Feds. It’s created by the Porsche toy shop under the Motorsports banner. We live in a Golden Age.
A two-seater, GT2 RS accelerates to 60 mph in 2.7 seconds, comparable to the acceleration I found so intoxicating in the Turbo S a year ago, and yet every tenth under three seconds is like another universe, so startling is the acceleration. Top speed is 211 mph. It’s not a peaky engine, either, with a fat vein of torque, 553 lb-ft. Considering this is a rear-drive car, a predictable engine is a good idea.
A trim physique helps. Weighing in at 3241 pounds with a full tank of fuel, GT2 RS has a power-to-weight ratio of 4.63 pounds per horsepower. Order the $31,000 Weissach package, which includes lightweight elements like forged magnesium wheels, a carbon-fiber roof panel and various carbon-fiber suspension elements like anti-roll bars and axle links, and that figure drops to about 4.57 pounds per horsepower.
Bigger turbos and more boost pressure generate plenty of heat. Under heavy boost, water is sprayed across the intercooler surfaces to reduce the temperature of air being shoved into the combustion chambers. A newly developed titanium exhaust sheds 15 pounds compared to the 911 Turbo exhaust, and produces that special ping-tingy titanium sound. Like any turbo engine, old or new, this one will prove very happy on cold, dry mornings.
