Like the last Cayman GT4, expect this new car to be the end-all-be-all of the 718 platform. If the wing didn't give it away, just look at the aggressive front splitter or at the snow-covered diffuser. This car isn't screwing around. Like the last GT4, the front bumper draws influence from the current 911 GT3. The only thing that looks missing is some additional bodywork around the side air intakes.
Expect less weight and more power, though what rests at the heart has not yet been determined. Rumors continue to suggest that the GT4 will swap in a flat-six in place of the 718's turbo flat-four, but that's simply hope and speculation. What's almost a given is that the GT4 will retain a manual transmission.
The car has been in development for a while, so don't expect to wait too much longer before the reveal. The Geneva Motor Show is coming up in just a few weeks, so we might get lucky there.
