Earlier this month, Porsche announced the 718 Cayman GT4 Clubsport. As the racing version of the Cayman, it comes in two versions: one for amateurs and one for professionals. Soon, we expect Porsche to reveal a street-legal Cayman GT4, as well as a Boxster Spyder that uses the same powertrain. But will they get the Clubsport's 3.8-liter flat-six?

Our spy photographer caught this Boxster Spyder prototype during winter testing in Europe. It's essentially undisguised, showing off its folding roof and double-bubble tonneau. Opinions will probably be split over whether it's better-looking than its predecessor, the 2016 Boxster Spyder. But even if you're not a fan of the styling, it may still win you over with its powertrain.

That's because our photographer repeated a rumor we've been hearing for a while. Supposedly, the 718 Boxster Spyder (and Cayman GT4) won't get the old 3.8-liter. Instead, he believes Porsche plans to give both cars the 4.0-liter flat-six found in the 911 GT3. Considering how many different places we've heard the same thing, as well as how old the 3.8 is, we're inclined to believe it.

The question is, how much power will the Boxster Spyder actually make? In the GT3, that engine makes 500 hp and 339 lb-ft of torque, a power output that would make the Spyder an absolute blast to drive. But from what we've heard, Porsche plans to detune the engine to make it closer to 425 hp. Even down 75 hp, we have a feeling it will still be plenty quick. After all, the last 718 Boxster S we tested hit 60 mph in 4.3 seconds, and that car only made 350 hp.

So when will we find out for sure? It could be as soon as March when the Geneva motor show kicks off. But since the previous Boxster Spyder was revealed at the New York auto show, Porsche may wait until April. Either way, we're looking forward to it.
