Now that the 991-gen­er­a­tion 911 has been re­vealed, at­ten­tion is turn­ing to the hard­core GT3 vari­ant, which we’ve seen test­ing on pub­lic roads with min­i­mal dis­guise. The GT3 is ex­pected to con­sign an il­lus­tri­ous line of race-bred nat­u­rally as­pi­rated per­for­mance en­gines to the his­tory books, with sources close to Porsche sug­gest­ing it will adopt a tur­bocharged pow­er­plant.

Although not yet of­fi­cially con­firmed, it would bring the 2020 911 GT3 and its more fo­cused GT3 RS sib­ling into line with the rest of the range. Both are ex­pected to use a twin-turbo 3.8-litre flat six shared with the up­com­ing 911 Turbo. Power will be brought down from around 570bhp in the Turbo to some­where in the re­gion of 513bhp for the GT3.

That’s a 20bhp in­crease over to­day’s nat­u­rally as­pi­rated 911 GT3, but the big­gest boost will come in the car’s torque out­put. In the 911 Turbo, this en­gine is set to pro­duce 524lb ft be­tween 2200rpm and 4000rpm. That com­pares with 339lb ft be­tween 6000rpm and 9000rpm for to­day’s GT3.

As be­fore, ex­pect weight-sav­ing mea­sures across the board, changes to the sus­pen­sion over lesser 911s, and the choice of man­ual and dual-clutch au­to­matic gear­boxes. The GT3 is due to go on sale in 2020.
