Porsche's next 911 GT3 has been spied testing again in Europe, and new reports suggest the naturally-aspirated 991 range's performance flagship will debut in March.

According to Britain's Autocar magazine, Porsche insiders have confirmed a Geneva Motor Show debut for the new hero.

Painted black and wearing scarcely any camouflage, the prototype spied here carries a number of uniquely-GT3 styling cues. Spotted alongside its predecessor, the differences are clear.

Chief among these is the nose vent mounted just ahead of the bonnet's leading edge, which, along with the enlarged cheek vents, helps provide more airflow to the various heat exchangers mounted in the GT3's snout.

At the rear there's a pair of centrally-mounted exhaust tips, just like the current GT3.

The aluminium scaffolding that supports the current GT3's rear wing appear to have been ditched, however. In their place is a more conventional looking wing that sits above a fixed 'whaletail' spoiler atop the 911's engine cover.

Previous spy photos of a cammed-up GT3 prototype showed this wing in an extended position, so it appears Porsche will take a more high-tech approach with the 991 GT3's aerodynamic aids.

Unlike previously-spied 911 Turbo and GT3 test mules, this GT3 flaunts a set of centre-lock alloy racing wheels - confirming that the ultra-pricey motorsport-grade wheels will continue to be offered as an option.

The new-gen 991 911 GT3 is expected to drop more than 40kg compared to its predecessor, and output from its 3.8 litre naturally-aspirated flat-six is expected to be on par with the current 331kW/430Nm GT3 RS.
