It’s been nearly two months since we last saw the upcoming 911 GT3 RS testing on public roads. Last time it was spotted, the road-legal race car was resting in downtown Atlanta with very little camouflage covering its body. As we started wondering whether we’d see it again in 2014, our spy photographers made sure we don’t miss it until 2015 by sending a set of brand-new shots our way. As winter takes over most of Northern Europe, Porsche engineers had no choice but to hone the 911 GT3 RS in the snow. Although there’s no drifting on ice, the good news if the track-focused sports car is nearly free of camo.

Of course, there’s still a lot of mystery around the brand-new GT3 RS, mostly in regards to the engine fitted in the rear. On the other hand, with the official unveiling rumored to take place at the 2015 Geneva Motor Show in March, more details should surface over the next couple of months.

The car’s exterior is far from being a secret, as a scale model car that surfaced the Interwebz in October 2014 revealed the GT3 RS’ new body shell. Not surprising, this test car boasts the exact same features seen on the miniature, including the vented rear fenders, the louvered front fenders, as well as the updated body kit, including the massive rear wing. What makes this prototype seem different when compared to the model car is the fact that the massive air intakes sculpted in the front bumper are covered by black tape, making the entire piece look like a snow plow. Not to worry though, these will come off soon and the GT3 RS will regain its aggressive front fascia.

The engine that will motivate the sports car is still unknown. Past reports have suggested the RS will get a turbocharged flat-six and the vented rear fenders helped fuel those rumors. But as we move closer to the vehicle’s launch date, it appears as if the turbo scenario has been dropped, with new reports talking about a naturally aspirated unit. What’s more, word has it Porsche might even replace the 3.8-liter flat-six with a slightly larger, 4.0-liter powerplant. A similar engine was used in the 997-generation GT3 RS 4.0, when Porsche increased displacement for more power. If this proves to be the case with the 991 model too, we’re about to get a 520-horsepower GT3 RS, along with keeping the nameplate’s all-motor heritage intact. Here’s to hoping!

Why it matters

It’s good to see GT3 RS development is well underway. With only three months left until the sports car breaks cover at the 2015 Geneva Motor Show, the RS is likely nearly ready to hit the assembly line. This means we will be able to see it in all its aerodynamic glory soon enough, as well as find out more about the engine that’s been quite the mystery throughout 2014.
