Porsche’s new-for-2019 GT4 contender has broken cover, with the new-generation Cayman GT4 Clubsport spied testing at Monza this week.

The car, believed to be based on the yet-to-be-launched Porsche 718 Cayman GT4, is expected to replace the current GT4 Clubsport MR in the German manufacturer’s customer racing lineup.

It is believed to feature an upgraded 3.8-liter flat-six powerplant, although multiple automotive publications have pointed to the road car utilizing a detuned version of the 4.0-liter flat-six found in the new 911 GT3.

While other details have been scarce, Sportscar365 understands that Porsche has already held private on-track events, including an outing at Daytona International Speedway in late July, for prospective customers.

Head of Porsche Motorsport Dr. Frank-Steffen Walliser wouldn’t confirm any details of the new Cayman GT4, other than that it will be racing next year.

“I cannot comment in detail on it but as a road car, this is way stricter on what we can announce,” he told Sportscar365.

“We have to stick with the plan for the road car. The race car has to follow the communications. But we’re doing something interesting.”

The new road and race cars are expected to be formally unveiled early next year.

    This should be the highest end of the GT4 field; McLaren, Audi and MB GT4s need to change and frankly a McLaren GT4 seems out of place. I understand the economy of scales at making a racer off of the same platform for multiple classes and know that limits the standard manufacturers who usually race but it just seems odd to have the range of cars and how much the high end have to be restricted. MB could be tough to have a true GT4 car from their lineup. Audi should be running the TT as their GT4 car over the R8. As unclear as the GT2 rules are I think it could allow the manufacturers to run their high end cars in 2 classes and make some of that back but I think they won’t sell near as many GT2s as GT4s.

      I agree. I feel like this is bad for sales as well. Your average person that goes to a race and is not a diehard fan will see a Mustang beating an Audi R8 or a Mclaren and will just go out and buy a Mustang and get the same performance for a fraction of the cost.

      I get it’s a different “crowd” of consumers but I would think Audi and McLaren would lose sales to Lamborghini and Ferrari just on the fact that there cars are not losing to Mustangs.

        I would argue the higher end teams are racing to sell race cars not necessarily street cars. I’d say Lexus and MB are trying to sell the sporting pedigree of the car, to a lesser extent Audi and Acura, Porsche everyone knows and Lamborghini sells kit to punters. I wouldn’t say there much crossover between even ZR1 Vette or Avezzano buyers and the more exotic cars, never mind Cayman, Mustang and Camaro, or even Sin/KTM.

      Merc has the AMG C63, Audi has the RS5. Both would fit in the class better. GT4 (and GT3 for that matter) needs a cost cap both on the race car and the MSRP of the base vehicle.

    What a great car. GT4 with a GT3 engine? Hell yeah. I have a GT3 now, but would love to get the new GT4 on the track..

    I laugh like hell every time a Mustang beats a field full of McLaren’s, Audi, Mercedes and even Porsche’s even though I know the racing versions are not that far apart in cost.
