Porsche wants to make sure that it keeps its race cars somewhat accessible.The German marque has filled the vacant 718-sized hole in its customer race car lineup with the new 911 Challenge. The company says that the model, which is based on the sports car's street-legal GT3 variant, will serve as its new "entry-level" racer.More from Robb ReportEx-MLB Pitcher Cole Hamels's Former Missouri Estate Is Headed to AuctionLand Rover's All-Electric Defender Has Been Delayed Until the 2030s: ReportFour Roses Just Dropped a New Cask-Finished Whiskey Aged in Honey BarrelsAdvertisementAdvertisementThe 911 Challenge is aimed at Porsche customers who are looking to get into racing but were unable to snag an example of the discontinued 718 Cayman GT4 RS Clubsport. From the 2027 season onward, the new model will be eligible for several one-make competitions worldwide, including the newly established Porsche Sprint Trophy Porsche Owners Club series. Its arrival also means that all four of the company's current customer race cars (the GT3 R, Cup, and GT4 R are the other three) are based on its most iconic model.Porsche 911 ChallengeThe Challenge is powered by the same 4.0-liter flat-six found in the 992.2-generation GT3 road car mated to a seven-speed PDK gearbox. Here, the mid-mounted engine makes 508 hp, 347 ft lbs of torque and revs up to 9,000 rpm. The slight boost in power—the standard vehicle makes 502 hp and 331 ft lbs of torque—can be attributed to a less restrictive exhaust system, according to Car and Driver.That power bump, as slight as it may be, is far from the only thing that differentiates the race car from its road-going counterpart. The Challenge may borrow the GT3 aggressive aero package, chassis, and powertrain, but the interior could not be more different. Nearly all of the latter's creature comforts have been done away with. In their place is a welded-in roll cage, a fire suppression system, and a single adjustable racing seat with a six-point harness. Porsche, thankfully, did keep air conditioning system, though. Other changes include an air jack system, a 110-liter fuel tank, and 18-inch wheels with a five-bolt pattern that you'll want to fit with racing slicks.Inside the 911 ChallengeReady to put your driving skills to the test against other Porsche owners? The track-only 911 Challenge is set to go on sale next year—though an exact date has yet to be announced—and will cost $275,000. That may seem like a lot for an entry-level vehicle, but it's also not that much different from a standard GT3 with some premium options included.AdvertisementAdvertisementClick here for more photos of the Porsche 911 Challenge.Best of Robb ReportThe 2024 Chevy C8 Corvette: Everything We Know About the Powerful Mid-Engine BeastThe World's Best Superyacht ShipyardsThe ABCs of Chartering a YachtSign up for RobbReports's Newsletter.
