Porsche seems to be hard at work developing the next-generation 911 range, and the latest prototype unit seen in this set of pictures could well be the upcoming 911 GT3, judging by the flared wheel arches and centrally-mounted exhaust pipes.
However, this test mule, which was caught making rounds at the Nürburgring, is missing the typical fixed GT wing of the 911 GT3. Things like the front lip and rear bumper are kept masked, although oddly enough it features the active rear spoiler that we’ve seen on its “lesser” siblings. However, this could change when the production model is out.
The coupé will also be joined by the 911 GT3 Cabriolet, and it’s possible that Porsche might offer customers with a six-speed manual transmission. While all that sounds fine and dandy, remember, there is a possibility that the forthcoming 911 GT3 could lose its naturally-aspirated 4.0 litre engine in favour of a smaller, turbocharged flat-six unit.
According to a source who has direct links to Porsche Motorsport, the next 911 GT3 could get a heavily reworked version of the 911 Turbo‘s existing 3.8 litre twin-turbocharged Boxer engine. The flat-six petrol mill currently packs 540 hp in the Turbo and 580 hp in the Turbo S.
As for the outgoing GT3, it’s equipped with a 4.0 litre naturally aspirated flat-six developing 500 hp and 460 Nm of torque. If Porsche chooses to go with the blown mill, the new GT3 could get anywhere upwards of 520 hp, as well as a massive spike in torque. Comparatively, the blown 3.8 litre flat-six in the Turbo makes 660 Nm of torque (up to 710 Nm with overboost).
