Porsche 911 Challenge Is a GT3 Made Just for TrackPorsche"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links."The Porsche 911 has a long, proud legacy of success on both the road and on the track—which is something you likely know, as you're a loyal reader of Road & Track. That also means you're likely gonna be quite interested in the carmaker's latest racing machine, which aims to further shrink the distance between street car and competition weapon by using a bevy of parts from the beloved 911 GT3 to keep costs down.First and foremost, the new 911 Challenge is not street-legal; Porsche spells that out very clearly in its press release. Instead, the car—which is meant to take the bottom rung of the Porsche Motorsport ladder previously held by the 718 Cayman GT4 RS Clubsport—will be eligible for the Porsche Sprint and Endurance Challenge North America by Yokohama, the Porsche Sprint Trophy Porsche Club of America by Yokohama, and the Porsche Sprint Trophy Porsche Owners Club racing series; any season entrants in those will get first crack at the U.S.-bound cars, but down the road, the company expects to offer it more broadly to anyone looking for a good track-day workhorse or testing machine.PorschePop open the back, and you'll spy a 911 GT3-based 4.0-liter boxer-six that makes 508 horsepower at 8500 rpm, with a 9000-rpm redline coming up shortly thereafter, and ABS, traction control, ESC and Porsche Torque Vectoring Plus to help noobs wrangle the grunt. There's a seven-speed PDK gearbox that offers a choice of manual or automatic operation. Stop gawking at the former 911 GT3 RS's awesome steering wheel and you'll find an adjustable racing bucket with six-point harness, but the carpeting, sound-deadening material, and trim has all been tossed out. All body dimensions and key components are shared with the car R&T's Lucas Bell described as "enjoyable almost all of the time" at last year's Performance Car Of The Year test.AdvertisementAdvertisement"Since their introduction, the roadgoing GT3 models have shaped Porsche's identity as a sports car manufacturer like almost no other model range," said Thomas Laudenbach, vice president of Porsche Motorsport, in a statement. "They are conceived and developed in close collaboration with motorsport. With the 911 Challenge, this tradition is being expanded to include a model that allows new customer groups to experience the thrill of motorsport in a 911."PorscheBut if you're thinking the Challenge is just a stripped-out GT3, far from it. The chassis has been upgraded with components from the 911 Cup car, while the shocks have been retuned for track use, and an integrated air jack system comes standard. A welded-in roll cage is, unsurprisingly, present, as is a 29-gallon FIA FT3 fuel cell.PorscheThe 911 Challenge is now available to order for 2027 Porsche One-Make entrants at a price of $275,000, which includes import and delivery to the United States. Considering the 911 GT4 starts a full $100,000 above that and even the cheapest 992.1-gen 911 GT3 RS goes for around $440,000 these days, that almost feels like a bargain.You Might Also LikeIf You Can Only Own One Car, Make It One of TheseThese Are the Most Popular Cars by State
