Default 2019 Porsche 991.2 GT3 RS unveiled with 520 horsepower

The most powerful naturally aspirated series-production 911 ever

2019 Porsche 911 GT3 RS: It Looks Bad-Ass Because It Is
Porsche's newest track wizard is here.


The 2019 Porsche 911 GT3 RS is Stuttgart’s answer to those who find that the $300,000-ish GT2 RS is out of reach. To the eye, the track-ready GT3 RS looks much like that one-digit-smaller, megapower Nürburgring blitzer, as the two cars’ wide-bodied exteriors share quite a lot, including carbon-fiber front fenders with heat extractors and a carbon-fiber hood punched through with NACA ducts to cool the standard iron brake rotors or optional carbon-ceramic units. The front fascia carries over from the standard GT3, although a more aggressive splitter is fitted to its lower edge for increased downforce. Intakes are sculpted into the fenders to draw air into the engine coolers, and there is an RS-specific rear bumper with larger side intakes. The manually adjustable carbon-fiber rear wing and rear underbody diffuser create additional downforce to keep the standard Michelin Sport Cup 2 rubber pushed securely into the tarmac at the GT3 RS’s claimed top speed of 193 mph.
What did we learn about the car from riding in the passenger seat for two laps with world champion rally driver Walter Röhrl at the wheel as he navigated a frozen road course, mostly sideways, in northern Finland? Not a whole lot, beyond confirming yet again that Röhrl is a far better driver than we are and that we remain mesmerized by the sound of six air-intake trumpets tuned to the key of H-flat.

For RS duty, Porsche’s screaming naturally aspirated 4.0-liter flat-six is tweaked to churn out 520 horsepower, a bump of 20 horsepower over non-RS GT3s. The additional power is squeezed from the engine—which has the same strengthened block and lightweight valvetrain as the standard GT3—via a new intake and titanium exhaust system that breathe more efficiently, while an updated engine calibration keeps the timing curve in check. Sorry, manual fans: torque will be routed to the rear wheels solely through Porsche’s seven-speed PDK dual-clutch automatic transmission. Other tricks for the track include dynamic engine mounts, a torque-vectoring electronic rear differential, and rear-wheel steering—all standard equipment. Suspension amendments parallel those on the GT2 RS: more rigid ball joints on the suspension links in place of rubber bushings and helper springs in the front and rear, in this case tuned specifically for the GT3 RS.

The GT3 RS stays light on its toes with body panels made from carbon fiber, aluminum, and magnesium. The interior is a sea of carbon-fiber trimmings and microsuede upholstery, and, as in the normal GT3, the cramped rear seat is removed. Further weight-saving measures for the RS include feather-light glass in the rear and sides, lighter door panels with nylon door-opening straps, and less sound insulation, because who doesn’t want to hear that sweet engine spin to 9000 rpm? Aggressively bolstered bucket seats keep organs in check when the surely staggeringly high lateral-acceleration limits are reached. In European markets, the RS will come equipped with a titanium roll cage; unfortunately, federal regulations in the United States will not allow such awesomeness for us. Opting for the $18,000 Weissach package pares what little fat remains (around 13 pounds, according to Porsche) by swapping out the magnesium roof for a carbon-fiber one and installing trick front and rear anti-roll-bar links constructed of the same material. Available separately for $13,000 are ultralight magnesium wheels to minimize unsprung mass in this track specialist.
Starting at $188,550, the 2019 Porsche 911 GT3 RS is a relative bargain when put next to the other animal wearing the RS badge, the 700-hp twin-turbocharged GT2. It’ll be money well spent if our previous experience with the outgoing GT3 RS is any indicator. Orders are being accepted now with deliveries expected in the fall of 2018.

There's more power

Of course there’s more power. But this is a Porsche RS, so we’re talking incremental here. It wouldn’t do that the standard GT3 matches the 500-odd horsepower output of the old GT3 RS, unless the new car increases the stakes even further. So, Porsche has liberated a few more ponies from the 4.0-litre flat-six for a 520bhp ‘maximum’. That’s pretty conservative; Porsche insiders admit it could have homologated a figure more like 530bhp, but the folks there like to be modest. That also means it should be able to produce its quoted 0-62mph time of 3.2 seconds everywhere - whether you’re doing so on a hot desert road in Dubai, or the slip road onto an unrestricted autobahn in the GT3 RS’s motherland.




It goes up to 9…

That’s thousand, revs, and again in line with the GT3’s screaming, naturally aspirated flat-six. That’s also 200rpm up on its predecessor. In the back of the RS, it breathes differently over the mere GT3, thanks to the Turbo-derived body’s intakes in front of the rear wheels, while there’s a different exhaust, too. It’s not about power but immediacy, say Porsche’s people, so everything from the breathing, electronics and more has been worked on to make the engine react that little bit quicker. We’ve sat alongside Mr W. Rohrl driving it on a frozen Finnish lake and he tells us it’s “much better”, and we’re not about to argue the toss with a driving god.



It's lighter, naturally

It wouldn’t be an RS without some weight savings, after all; the GT department has taken 5kg out of the carpets alone. Thing is, the internet forums will be ablaze with keyboard heroes, as Porsche won’t legally be able to quote its new RS in its very lightest specification, as it has previously. It’ll likely be the same weight as the outgoing car on paper, then - 1420kg, if it’s not ingrained in your RS grey matter reference library - so get ready for some angry internet people. It is all apparently down to a change in the way cars are homologated, something to do with options and percentages of weight. Anyway, if you want a super-light RS, there’ll be the option of the Weissach Pack, as per the GT2 RS, with magnesium wheels, and carbon body parts (the roof and bonnet) combining to help shed around 29kg from the kerbweight and a chunk more from your wallet.




The GT3 RS has gone green

Not in the environmental sense, but the colour. Porsche is calling it Lizard Green. The launch colour of the GT3 RS is the result of GT car boss, Andreas Preuninger, seeing a similarly coloured vintage RS at Rennsport Reunion in the USA a few years ago. Apparently the production team asked if he was crazy, but Porsche has form introducing, or re-evoking, classic colours with the RS - notably Lava Orange and Ultra Violet with the last 911 GT3 RS car. It’s not the first green RS, remember – Viper Green was one of the launch colours of the 997 GT3 RS. Like its 997 predecessor, the new GT3 RS brings back the GT3 RS graphics down the sills, just in case the massive rear spoiler, punctured front wings and channelled bonnet and roof aren’t tell-tales enough.



Porsche reckons it'll do 7m 05s at the 'Ring

As sure as GT3 RS follows GT3, the new RS will chase its tyre-tracks around the Nürburgring. The standard GT3’s lap time is now 7 minutes 12.7 seconds (better than the old GT3 RS’s 7 min 20 secs) so it has that to beat. What is certain is it’ll not get close to its turbo-nutter 700hp GT2 RS relation’s bonkers 6 min 47.3 second time, but Andreas Preuninger says: “I think it will end up at 7 minutes 5 seconds or something like that. It’s hugely quick.” Most of that, says the GT boss, is down to the tyre and chassis revisions, only around 1 second or so attributable to the marginally increased output from its engine.



It's essentially a GT2 RS underneath

Basically the bits underneath are GT2 RS, so that means every joint in the suspension is solid-mounted – bar a single one that’s related to the rear-wheel-steering system. That rear-axle steering itself has been finessed to improve speed and turn-in response at lower speeds, as well as aiding stability at higher ones. The spring and damper rates are all but identical to its big brother, too, and having driven that on UK roads, it achieves a beguiling mix of composure yet authoritative control. It’ll ride even better still if you option that Weissach Package, as the magnesium wheels shave a total of 12.5kg off the unsprung weight. Spend more on the PCCB (i.e. carbon ceramic) brakes too and you’ll drop about the same amount again.



The aero's been honed

True to RS form, the way it exploits the air travelling up, over, around, through and under it has been finessed. The biggest change centres around those new NACA ducts on the bonnet. Again, they’re derived from the GT2 RS, channelling air though the body to help cool the front brakes. That helps airflow under the car too, while also cleaning up the air up and over to the body to the rear wing. The effectiveness of the NACA ducts still surprises the GT department – the initial goal was merely brake cooling; those other benefits a useful, unexpected gain. As Preuninger admits: “You wouldn’t believe how much empirical stuff is still involved; despite all the computers, you have to try it out.”



It’s good for business

Every time Porsche releases a new GT model, it cannot build them quickly enough. That’ll certainly be the case here, with the GT3 RS likely to be over-subscribed. The previous car sold nearly 5,000 units globally, and Porsche is always looking at ways to increase capacity on the 911 line. For UK customers, that’s likely to mean, as with the previous RS, that early customers will have to stick with the standard range of colours, because Porsche’s Paint to Sample option, where they’ll paint it any colour you like, would slow the build process too much. Likewise, delays in production for the magnesium wheels with the Weissach Pack mean it’ll be a two-stage option, with the earliest customers unable to order their car with those lightweight wheels.



It will only feature an automatic gearbox

Yes, as it’s an RS, forget any hope of doing any old-fashioned three-pedal foot and hand work in the stripped and caged interior. There’s always the GT3 Touring for that, or a GT3 without the no-cost PDK option. There is a man in America who had the previous GT3 RS converted to a manual by using a 911R six-speeder, but that’s something that’s unlikely to ever happen again – unless you know any different. Quite simply, the PDK is faster; finger-flipped paddles and seven gears mean that not a lot, short of a hypercar or GT2 RS, will have the capacity to come close on track. The PDK has, of course, been honed for the new GT3 RS, featuring different bearings inside, while the rear axle ratio differs to compensate for the larger (21-inch) rear wheel and tyre package the RS brings over the standard GT3.




The man behind it isn’t your typical idea of a German engineer

He’s been associated with Porsche’s GT division cars since the second-generation 996 GT3, but Andreas Preuninger isn’t what you’d imagine a typical engineer to be. He rides KTM dirt bikes in his spare time (taking the number plates off so dog-walkers can’t serve him up to the law), hand-builds electric guitars and amps with his son, competes in rifle- and pistol-shooting competitions, and has a bright yellow Dodge Ram pick-up with a 5.7-litre Hemi in it that he’s considering supercharging. That’s his “gardening truck”, apparently. If he’s not busy with all of that, or putting miles on development GT cars, he’ll be on his 600bhp boat dreaming up the next GT department creation. Apparently, the 911R was a product of such big-horsepower aquatic pondering…

I think the modern 911's would win, but I'm not sure it would be by as much as 14 years of development time would lead you to believe it to be.

Now, to wait for the inevitable reviews proclaiming this new GT3 RS the best factory turnkey street-able track car for under 200K. The lap times no doubt will be fun to see as well, I always get a kick out of seeing how closely these "underpowered" (vs. its competition, of course), naturally aspirated cars with the engine in the wrong place keep up with all the other cars in the segment that don't have these handicaps.

I think the 918's v8 motor has the Carrera GT's v10 beat by a few hp or so. Still would rather have the v10 though

I actually had that same thought and double checked the numbers before I posted. The V10 makes 603 HP, the V8 makes 600 HP. That's actually really impressive for the V8 though when you consider it displaces over a liter less. But, still, the Carrera technically wins for engine output alone, even if the 918's hybrid system lets it still win the total net HP crown.

Carrera GT 5.7 liter V-10 605 hp /435 lb feet torque 8400 Rpm Cut Off
918 Spyder 4.6 liter V-8 608 hp/398 lb feet torque 9150 Rpm Cut Off

Very close with the horsepower numbers, but torque, and I think engine note go to the Carrera GT's screaming, F1 sounding V-10. The 4.6 liter V-8 weighs in at a ridiculous for a road car 297 pounds..amazingly low for a double overhead cam dressed V-8 engine. The V-10 was still very light for its size, 5.7 liters and 10 cylinders at 472 pounds. Both are fabulous normally aspirated engines!

I guess I am a little underwhelmed with this version...not exactly the car I thought we may get...perhaps it is still coming but this look very much like the .1 GT3RS and I think not exactly worth the upgrade if you have one in the garage already? Of course if you don't then snag one!

Must get this car as it possesses all the Holy Trinity attributes that define a car owner's measure of success:

1. Centerlock wheels
2. NACA ducts
3. Cloth door pull handles

No production car in automotive history (GT2RS doesn't count for obvious reasons) has ever been made that possesses all three of these in a single vehicle offering.

Realistically you have to order this with the Weissach Package... so this is how it will actually look in the real word. A bit more wild track boy racer look than the 991.RS. Not that it's a bad thing, just a more "traditional" RS look. The flashy colors pop more to me without all the black bits everywhere.
