Porsche Motorsport has launched the all-new Porsche 911 GT3 R at the Nürburgring 24-Hour. The new 991 GT3 R joins the current factory race car lineup of 919 LMP1 Hybrid and 991 RSR, and the customer 991 Cup, which is built on the Stuttgart production line.
Based on the 991 GT3 RS, the 991 GT3 R comes with a four-litre flat-six making 500bhp and costs an impressive €429,000 plus VAT: almost $500,000 plus applicable taxes, according to fxtop.com. In comparison, the 991 Cup (GT3 based) with 460bhp from its 3.8-litre engine costs just €181,000* plus tax. So what do you get for your half-million dollars?
“In developing the latest 911 race car, special attention was paid to lightweight design, better aerodynamic efficiency, reducing consumption, improved handling, further optimised safety as well as lowering service and spare parts costs,” says the Porsche press release.
That lightweight design starts with aluminium, carbon fibre and polycarbonate: all the glazing – including the windscreen – is now polycarbonate (EB Motorsport sells a similar polycarbonate windscreen for early Porsche 911s if you’re in the market). The roof, front panels, doors, rear quarters and tail section are all carbon fibre.
Lowering body and suspension weight across the 991’s longer wheelbase (83mm longer than a 997) means an ‘optimised’ centre of gravity has been achieved. I presume that optimised means lower and further forward than the 997: no doubt one of my race engineer friends will fill me in on this over a beer some night.
One big change on the new GT3 R is a move to a centre front radiator. Anyone who has watched Supercup racing at Monaco knows that even a small hit to one front corner can wipe out a radiator and then a race motor too, as the damaged car limps back to the pits with soaring engine temps.
Going to a centre rad (as seen on older Porsche 911 race cars with centrally-mounted oil coolers) helps airflow and aerodynamics too, allowing more control of the hot air beneath the front wings and around the front axle. The 991 GT3 R brings in the same front wing vents from the 991 GT3 RS to reduce front end lift, but then the 997 GT3 R also had front wing vents: not a great deal is different.
Brakes at 6-piston 380mm front/4-piston 372mm rear are the same as GT3 Cup, and the wheels are also the same 310mm width at the rear. Paddle shift of the six-speed sequential transmission, direct injection, variable valve timing, 120-litre fuel cell: it’s all as one would expect from a top-flight Porsche racing car costing £370,000 including VAT.
Deliveries start in December this year, so we won’t see the Porsche 991 GT3 R on race tracks before 2016. How competitive will it be? That depends on who decides to run it, and what the competition does in the meantime. See below for some Porsche video of the new 911 GT3 R in action.
Porsche Racing had a disappointing run at yesterday’s Long Beach Grand Prix in California. Racing in the Tudor IMSA series ‘showcase’ at Long Beach, the 100-minute street race left little time to fight back from a low starting position.
While Richard Lietz and Patrick Pilet initially went well in qualifying, running P2 and P3 early on and driving the wheels off their Porsche 911 RSRs (see the video below), the cars started the race further down the field. The tight and twisty street circuit is tough for overtaking, so when Lietz put a move on Oliver Gavin’s Corvette at the start, there was no room for error. Sod’s Law, that is what happened.
“An accident at the start is something you can really do without, particularly on a street circuit like Long Beach,” said Lietz. “You know that the race is short and that overtaking is difficult, so you try everything to make up positions at the start. That didn’t work this time. I didn’t expect the Corvette to swerve towards me. I couldn’t avoid him and ended up in the wall.”
Looks more like he ended up in the Corvette (above), but Pilet made the most of his team mate’s misfortune, to come home in fourth place. “I was lucky in the first corner after the start. While Richard’s car was forced into the wall, I just managed to scrape through. Our car wasn’t easy to drive in the first laps, but it improved over the course of the race and the balance got better. In fact, we weren’t far off the top with our times. Still, on this narrow circuit it was impossible to overtake.”
IMSA Porsche Racing California
The number 911 RSR eventually finished eighth overall, with local driver and polesitter Bill Auberlene on the top step in the BMW Z4. No surprise to see a win from pole on this super short race. If you’re wondering why teams put all that time and money into racing an almost nonexistent event, look at where Long Beach is situated, just south of Los Angeles central. It’s the easiest place to market to those who won’t come to a circuit.
Not done the maths yet, but I think this keeps Porsche at the bottom of the championship table in the GT Le Mans class of the Tudor IMSA series. Next round is Laguna Seca at the start of May: another short race of just 2 hours 40 minutes, but with more room to get past the rest. We’ll have to see how things pan out with Michael Christensen in the number 911 RSR, while some of the boys come home for Spa WEC.

The awesome Kévin Estre will join the Porsche works drivers for the second round of this year’s World Endurance Championship (FIA WEC) at Spa Francorchamps. The current McLaren factory driver has been let off Woking’s leash to come play with 911s in Belgium.
Estre is a proper racing driver, as proved by his 2013 Carrera Cup Deutschland title. Anyone who wins this series – undoubtedly the world’s most challenging one-make championship – is a monster behind the wheel, especially when they beat Nicki Thiim as their Attempto Racing team mate.
Estre and the Porsche Works Drivers
I was surprised when Kévin did not get a Porsche works drive after winning that championship in such fine style. Stuttgart was rammed with pilots at the time, so I can see why they picked the lineup they went with. It is very exciting to have the 26 year-old Frenchman back in a 911: and the full-fat number 92 factory Porsche Manthey Racing RSR, at that.
Estre went to McLaren at the end of 2013 and made the most of the opportunity, outperforming expectations for the chassis. He also kept his hand in with Porsches, sharing a GT3R with Jaap van Lagen in GT Masters and picking up a couple of wins last year (below at Zandvoort).
Alongside the GT Masters wins and that 2013 Carrera Cup DE championship, Kévin was runner up in the Porsche Supercup that year, Rookie of the Year in 2012, and French Carrera Cup champion in 2011. Estre excels in the wet, so if it rains in Spa (not that unlikely), we are in for a proper 911 race.
Sharing the car is Sven Müller, the quick Porsche Junior who was very impressive in testing following his maiden win in Porsche Supercup at Monza last September. Muller was impressive at Spa, qualifying fourth and finishing just off the podium, behind Bamber, Thiim and Bachler. No shame there.
The Spa-Francorchamps round of the 2015 WEC season runs from May 1-2. You can watch the race live online if you know where to go: WEC rounds are also shown in full on Motors TV and Fox Sports.
Kevin Estre versus Sean Edwards Nürburgring video
Now for some video! Here’s Kévin racing Sean Edwards at the Nürburgring during his 2013 season. Christian Engelhart won this race, but the real action was behind, as Estre and Alex Riberas gave Sean a hard time. Running wide across the grass in the duel with Alex earned Sean a stop/go penalty, hence what happens at the end. Fantastic driving – Edwards was an old-school Nürburgring hero.
After a decent day one of the 2015 Circuit of Ireland Rally, the Tuthill Porsche 997 R-GT failed to leave the start line at the evening’s special stage around Newtownards town centre. The car was pushed out of stage on to a trailer and recovered to the service area.
By the time we got back, it was dark. Spectators surrounded the tent, with plenty of work ahead of us. The boys set the car up on jack stands and set to work on removing the gearbox. Just over half an hour later, the transmission was out and the clutch was exposed. It took engine builder Anthony just a few seconds to spot the issue: one clutch plate had lost all of its friction material.
Single Clutch Plate vs Mutiple Clutch Plate Pack
The clutch kit in most road cars consists of three main parts: single pressure plate, single friction plate and a release bearing. In competition cars like the 997 GT3 Cup on which the R-GT rally car is built, the cars run a set of multiple clutch plates, arranged in a clutch pack.
The advantage of a multi-plate clutch is that it can transmit higher levels of torque through a smaller diameter unit. The more plates there are, the more torque it can transmit, or the smaller the pack needs to be: Formula 1 clutch packs are about the size of your fist. The clutch pack in the 997 R-GT is a bigger diameter than an F1 pack, but smaller than a single plate road clutch.
With a carefully calculated number of plates in the assembly, the failure of one plate does not leave enough friction to drive the car. This is what happened to R-GT. As the team carries spare clutch packs, it was straightforward to fit new parts and get the 911 ready to restart day two of the rally.
Chief Engineer Graham Moore also decided to change all four dampers on the Porsche, to make driver Robert Woodside more comfortable behind the wheel. The car enjoyed a trouble free run through Day 2 and the team came home satisfied with a job well done.
Circuit of Ireland Porsche Rally Video
I put together a short video of our experience on the 2015 Circuit of Ireland Rally, which you can watch below. Enjoy the sights and sounds of the first modern Porsche to start this great rally for almost thirty years: it was cool to see it in person.
Just back from the 2015 Circuit of Ireland Rally with Tuthill Porsche, doing team media and shooting some video of the Porsche 911 R-GT rally car. As the first contemporary Porsche 911 rally car to take part in ‘The Circuit’ (as we call it in Ireland) for almost thirty years, this was a proper weekend, worthy of my volunteer status!
Circuit of Ireland Porsche drivers
Robert Woodside and co-driver Allan Harryman were in the car for this event: two great guys whose fathers have both won previous Circuits. Having set fastest stage times in the production class last year, they would be quick and precise. Testing went well and Robert put huge effort into sorting out some great sponsors for the event, including Karcher UK and Rushmere Shopping Centre: Ireland’s second-largest shopping mall.
I flew in on Thursday and went straight to service in Belfast’s Titanic Quarter. It’s eleven years since I was last in Belfast and it looks pretty different now! Titanic Quarter is based around the docks and slipways where the most famous ship in history was constructed. It’s super interesting and a great place for the rally HQ. We were right by the entrance, so our tent was surrounded by spectators throughout the weekend.
As soon as I arrived, we were off: the car was due in scrutineering and we had to make tracks. I’ve just started using a Sony HXR-NX30E camcorder (awesome device), so I had a little play with that as the car went through technical inspection and received official approval to take part. The Sony’s complete lens and sensor unit is internally stabilised – check out the video at the bottom.
Once back from scrutineering with permission to compete, we had a short while to change tyres and get the car ready for shakedown. Robert and Allan took over the Porsche from here, and did two runs on a closed course to see how the car felt (top pic). That all worked out fine, so then they headed off to Belfast City Centre for the ceremonial start, while we retired to the hotel to make preparations for the following day. More of this story tomorrow!
