You're looking at the most powerful naturally aspirated road going Porsche that money can buy.

We’ve seen spy images knocking around the place, but now the time has finally come to get a look at some of the first official shots of the new 911 GT3 RS, the quickest naturally aspirated version of the iconic car.

This will likely be the last hurrah for the 991 generation, and the photos show a Hulk-approved Lizard Green GT3 RS packing an extra 20bhp compared with the model before it. That means the naturally aspirated 4-litre six-cylinder engine now produces 513bhp at 8,250rpm.

The bump in output makes perfect sense considering the non-RS GT3 was updated last year when it received the 4-litre unit with 493bhp on tap. There’s no word about torque levels just yet, but we remind you that the lesser version and also the old RS both offer 339lb ft.

While the GT3 can be had with either a standard seven-speed manual or an optional dual-clutch automatic with the same number of gears, the hotter RS is expected to be PDK-only as before.

As a result of the newly gained muscle, Porsche has been able to shave off a tenth of a second from the 0-62mph sprint, which now takes only 3.2 seconds. Flat out, the mildly updated 911 GT3 RS will do 194mph, barely 1.2mph more than before.

Besides fiddling with the flat-six engine, which revs to a maximum 9,000rpm, Porsche has retuned the rear-wheel steering and has applied some discreet aerodynamic tweaks. These include new NACA-style ducts and a reshaped front bumper with different ducts to optimise airflow, along with a modified rear bumper boasting larger air extraction ducts.

The end plates of the rear wing have also gone through some changes, while the tail lights are a bit different to before. The wheels measure 20 inches at the front and 21 inches at the back and come with 265/35 and 325/30 tyres, respectively.

For an additional cost, Porsche will sell the 2018 GT3 RS with an optional Clubsport package that offers six-point seatbelts, fire extinguisher, and an aluminium roll cage.

We only have the one image of the interior available, but we know that there are going to be nylon opening loops on the lightweight door panels, racing seats with a carbonfibre shell, and less sound absorption material in a bid to further reduce weight. For the same purpose, there’s a new engine lid with lightweight construction.
