When McLaren rolled out its new 650S, we knew it would only be a matter of time before it would completely replace the 12C altogether. And that would include the racing version – not least because McLaren officials told us as much. And with the Goodwood Festival of Speed now getting underway in the UK, Woking's GT racing division has revealed its new GT3-spec racer.

The new McLaren 650S GT3 benefits from several key upgrades over the MP4-12C GT3 that's been competing for the past three seasons in racing series like the Blancpain Endurance Series and GT Asia championship – both of whose standings it currently leads – as well as the Pirelli World Challenge, European Le Mans Series and countless local racing series.

For starters, McLaren gave its GT racer a new face that not only more closely resemble the 650S (which, like the previous GT3, is also based on the 12C's chassis) but, along with the rest of the revised bodywork (and some rather intriguing-looking wing mirrors), is also more aerodynamically efficient to provide more downforce, better cooling and less drag. McLaren says the 650S GT3 also has a wider track, revised suspension geometry and will cost privateer teams less to run in whichever series they choose thanks to more robust components and a powertrain that can run longer between rebuilds. The cockpit has also been updated to make it more accommodating for drivers who often have to run it over long distances around the clock.

McLaren's familiar 3.8-liter twin-turbo V8 provides the motivation, mated to a six-speed competition-spec sequential gearbox. But while the same engine produces 641 horsepower in road-going spec, the FIA's Balance of Power regulations mandate it be limited to 493 hp. That actually makes it the least powerful model McLaren makes, but then, of course, the same regulations apply to all the cars against which it will be competing, so customer teams will be counting on the other revisions to help them stay at out ahead of GT3-spec versions of models like the Porsche 911 GT3, Aston Martin V12 Vantage, Mercedes-Benz SLS AMG, Ferrari 458 Italia and Bentley Continental GT.

McLaren GT says it plans to build 15 examples in time for the start of next season, each selling for £330,000 (before tax, or about $560k). However, teams already running the current 12C GT3 will have the opportunity to upgrade theirs to 650S spec as well. Scope out the full details in the press release below.

McLAREN GT UNVEILS LATEST GENERATION 650S GT3 AT GOODWOOD FESTIVAL OF SPEED 2014

- GT3 evolution featuring enhanced safety and optimised handling
- CFD developed aerodynamic package with improved cooling
- Limited production run to premiere on the grid for the 2015 season
- Upgrade kit available to 12C GT3 owners to extend competitive life of existing cars

In the grounds of the famous Goodwood Estate, McLaren GT has today confirmed first details of the McLaren 650S GT3 – the latest generation track-focused racer which will contest GT3 championships across the globe from the 2015 season. Building on the highly successful 12C GT3, which has firmly re-established McLaren at the front of the GT grid over the past three seasons, the 650S GT3 was unveiled in front of fans and the global motorsport media at the 2014 Goodwood Festival of Speed.

As the 12C GT3 continues claiming trophies around the world, the 650S GT3 has big shoes to fill, but it has been designed to do just that. The menacing and purposeful-looking racer is the second-generation GT3 car from McLaren GT, the GT race car building arm of McLaren, and follows in the slipstream of the 12C GT3, now competing in its third competitive season. To date, the 12C GT3 has secured three championship titles, 51 race victories and 71 further podiums, a number that continues to rise on a weekly basis, and currently leads the highly competitive Blancpain Endurance Series and the GT Asia championship.

Based on the recently unveiled McLaren 650S, and built around the same lightweight carbon fibre MonoCell chassis, the GT3 iteration has been honed using CFD technology and the latest in automotive and motorsport simulation to offer enhanced aerodynamics and improved levels of cooling. At the front, an aggressive splitter and larger air intakes dominate the purposeful new look, incorporating the familiar McLaren 'face' – albeit a more aggressive and menacing version, while on the flanks, the all-new lightweight carbon fibre bodywork wraps around reprofiled air intakes, which offer further optimised cooling. The fixed carbon fibre rear wing works in tandem with the large carbon fibre splitter to complete the management of air as it is worked across, through and beneath the sleek lines of the 650S GT3.

The road-going version has been designed and developed to provide 'the ultimate in driver engagement on the road', and the 650S GT3 uses this same approach. Revised suspension geometry, wider track and updates to the overall setup provide enhanced levels of drivability, optimising engagement for the wide range of drivers competing in GT racing. In addition, the updates have been made with added emphasis on endurance racing, pulling from the learnings over the past few years, and responding to feedback from the customer teams.

Reduced cost of ownership has been a priority during the design and development of the 650S GT3, and this has been achieved through extended component life, including increased engine and gearbox rebuild intervals, together with re-designed components and systems to reduce parts costs. Body panel design and fit have also been optimised which will not only minimise pit lane repair times but also aids weight distribution through the use of lighter components.

Increased levels of safety and refinement for the driver

Inside the cockpit, the 650S GT3 provides improved levels safety for the driver. Protection offered by the carbon fibre MonoCell chassis is further enhanced with the addition of an FIA-approved rollcage. Redesigned and lighter than that of the 12C GT3, the 650S GT3 rollcage provides a greater degree of driver comfort, with increased leg and headroom.

Another key area that has been optimised is the level of refinement, underlining the focus on endurance and driver engagement. As with its predecessor, the 650S GT3 is fitted with a bespoke motorsport digital dash display which sits behind the unique 650S GT3 steering wheel, inspired by the wheel design seen in the McLaren Mercedes Formula 1™ car. New to the 650S GT3 is a fully FIA-approved McLaren GT-developed race seat, fitted with a six-point race harness as standard. This seat offers increased levels of support and driver comfort through the use of bespoke moulded seat inserts.

The layout within the cockpit has been revised to make it even more driver-focused than previously. The seat is directly mounted to the chassis, and the steering wheel and all-new motorsport pedalbox are then adjustable to bring them closer to the driver. The centre console is also developed from the latest 12C GT3 interior, reducing complexity, and features a membrane-type switch panel for ease of use. In addition to this, improvements have been made to further optimise ventilation and driver cooling.

Award-winning technology, optimised cooling

The 650S GT3 is equipped with the latest generation of the award-winning, 3.8-litre McLaren V8 twin turbo 'M838T' engine. Race-prepared and including a McLaren-developed ECU offering increased functionality to incorporate turbo boost and transmission shift control, the engine is coupled to an all-new six-speed sequential motorsport transmission. The 650S GT3 produces around 500PS – the same power as the 12C GT3, which is controlled by the FIA's Balance of Performance (BOP) regulations. Cooling is improved through larger 650S intakes within the front bumper and re-profiled side intakes. In addition to this, the gearbox oil cooler has been relocated, now incorporated into the larger side intakes, giving the rear of the car a cleaner, more aerodynamic flow.

Race tuned with increased grip

The 650S GT3 uses an all-new race-tuned suspension system with a 52mm wider track than the 12C GT3. The front suspension also allows the fitment of the latest generation larger diameter racing tyres . In conjunction with the optimised aerodynamic package, this provides increased levels of front-end grip and steering feel on turn-in. Newly designed forged aluminium wheels (front - 12.5" x 18", rear – 13" x 18") are held in place with a single wheel retaining nut on motorsport axles, while a revised hub bearing assembly and extended-life suspension components are another example of a simplified service item, and reduced maintenance costs.

Behind the new design eight-spoke wheels, and bringing the power, aerodynamics and downforce under control is a newly-developed braking system with monoblock six-piston callipers on the front, and four-piston on the rear, with ventilated discs (380 x 35mm front / 355 x 32mm rear).

Existing owners can upgrade

The 650S GT3 development programme has pulled significant data from the findings and lessons learned from the 12C GT3 programme. Testing of the 650S GT3 will continue throughout the summer with customer car production commencing in the autumn. Pricing for the 650S GT3 has been confirmed – £330,000 ex works, plus tax.

Existing owners of the 12C GT3 are also able to benefit from the updates and enhancements offered by the 650S GT3, due to the use of the shared chassis structure and award winning engine. This upgrade package further extends the life of existing 12C GT3 cars allowing them to continue racing competitively through a second GT racing life cycle. For many McLaren GT3 owners this allows them to race their existing car for an average of six seasons.

Around 15 examples of the 650S GT3 are planned to be produced and delivered for the start of the 2015 season. With the optional upgrade package for 12C GT3, this could see an additional 15 cars running the new design from next season.

Mike Flewitt, Chief Executive Officer, McLaren Automotive:

'The McLaren 650S GT3 is to GT racing what the 650S is to McLaren Automotive, with the new car improving on all areas of a strong existing product, and making it more engaging at the same time. It shares the heart and soul of its road-going sibling with the same 3.8-litre twin turbo engine and the carbon fibre chassis, but turns things up to 11 in terms of aerodynamics. It is truly fit for purpose, but is now accessible to an even wider breadth of abilities and, as with the road car, it provides unprecedented levels of comfort, safety and driver engagement.'

Andrew Kirkaldy, Managing Director, McLaren GT:

'The 650S GT3 is a natural progression of an already successful racer, but we have looked at all the different areas where we could possibly make even the slightest incremental improvement. The revised aerodynamic profile looks much more purposeful, and we have managed to incorporate increased levels of cooling without any detriment to performance. A big step forward has also been made in terms of servicing the car, which can be the difference between a race win and finishing off the podium, and the cost of running a car at a competitive level, and this becomes more important the longer and more demanding the event. By simplifying maintenance and repair processes, and cutting down the time and costs involved, the 650S GT3 will be even more competitive at the longer endurance events with time required in the pitlane reduced to a minimum.'

'Throughout the development programme, we have focused on making the 650S GT3 even more enjoyable and engaging to drive for the wide range of drivers that are competing in GT racing around the world. With a broader envelope of performance, which is easier to access, more drivers will be able to exploit the true potential of the 650S GT3. One example is with the wider track, which gives greater levels of grip and improves handling.'

Chris Goodwin, Chief Test Driver, McLaren Automotive:

'This is a car that is improving on a race-winning formula, and is designed and built to offer even greater levels of driver involvement, but also to be easier to drive. This is a crucial factor in any racing car, but especially with long-distance and endurance racing, where drivers can double or even triple stint, where we compete on a huge variety of circuits and where weather and track conditions vary regularly throughout a race.

'GT racing attracts a wide variety of drivers - from the best and most experienced professionals in the world to ambitious amateurs and young developing talents. If the car is easy to drive and gives good feedback as you approach and sometimes exceed the limit, the driver will be better able to drive consistently, error free and extract more out of the car lap after lap. This is key for professional race winner as much as it is for the amateur racers that are making up increasingly large proportions of the grids around the world. It is the result of continuous development, both in terms of the work carried out by the McLaren GT design and development team, but it also takes the learnings from the thousands of laps, from countless circuits across the globe which have been completed by the 12C GT3 with our highly-successful, race winning customer teams. Real-world data and feedback from the teams gives us a much clearer understanding of what the cars go through which no simulator can provide. As such, the 650S GT3 will be just as competitive in the right hands, but more forgiving for the less experienced drivers that are being attracted to the exciting GT3 championships around the world.

'The 12C GT3 was the first iteration of a GT car from McLaren, and was, and still is competing and winning on a regular basis. The 650S GT3 is now our second generation model, and it is up against more established rivals, many of which are on to the third, or in some cases, fourth. Just as we face in the road car market. Despite this, McLaren is still the brand to beat.'

What's in a number? 59 - a winning pedigree

The car unveiled carries the Goodwood Festival of Speed theme of 'addicted to winning', with its livery including the number 59. The number was carried by the now legendary McLaren F1 GTR chassis #01R at the 24 Hours of Le Mans in 1995, and claimed victory in the gruelling test of endurance on its debut – a feat that had never been achieved previously, and has not been repeated since. Deliveries of the 650S GT3 will commence from late 2014, and the competitive debut with customer teams in GT3-homologated series will start in 2015, 20 years on from the famous race victory.

      I really like how McLaren lets teams with older models upgrade their cars to the most up to date equipment. They do this with their road cars too and I think that gives their cars a lot more value..especially for customers that want the latest and greatest,

      I was thinking they were channelling the air through and around the mirror glass to reduce the frontal area of the mirror and therefore to cut wind resistance...

      The "intriguing-looking mirrors" are hollow shells designed to channel cold air to the cabin. Also, Aston Martin doesn't produce GT3 version of V12 Vantage to my knowledge. Only V8 Vantage is available as GT3 car.

        Actually the V12s only run GT3/GTD spec. The V8s are used in GTE. TRG has built a few GT3 and GT4 spec V12 cars for TUSCC and PWC.
