Development cars for the 992-generation Porsche 911 Turbo are out and about again, this time running tests in hotter conditions compared to its previous sighting.

Given that the Carrera S and Carrera 4S models carry over the 3.0 litre biturbo flat-six from the latter part of the 991-generation model‘s lifecycle, the 992 Turbo should follow suit in also using the 3.8 litre flat-six capacity and configuration of its predecessor, albeit with uprated outputs to make it the most potent version outside of the GT range.

The forthcoming 992-generation 911 Turbo could boast of at least 580 hp, a figure attained by the 991-generation Turbo S facelift of 2016, and driveline will almost certainly be a dual-clutch gearbox sending power to all four wheels, likely featuring torque vectoring and rear-axle steering as well. Turbochargers are likely to continue to be variable turbine geometry units as well for the 992 model.

A selection of Turbo visual cues are carried over; the front bumper here should add some aggression to the overall Carrera bumper shape, albeit with dual-strip DRLs similar to the 991.2 Turbos, while yet-to-be-revealed Turbo-specific wheels and tyres should house uprated brakes and a Turbo-specific suspension tune. Air intakes ahead of the widened rear wheel arches further signify the Turbo from the core 911 range.

At the back, the 992 Turbo gets a deployable rear spoiler atop a fixed ducktail section – a Turbo signature since the 996-generation model. The capital ‘T’ Turbo also appears to use a restyled version of the 991 Turbo’s quad-trapezoidal exhaust outlets, as well as rear bumper vents outboard of the exhausts.

Save for the modest use of shrouds and camouflage foil, the 992-generation 911 Turbo should be reasonably close to production readiness – could a Frankfurt Motor Show debut be on the cards?
