All-new McLaren Artura GT4 to make global public debut this week at the Goodwood Festival of Speed

2023 McLaren Artura GT4 - Side View

McLaren Motorsport today reveals the new Artura GT4 race car, ahead of its global public debut at the Goodwood Festival of Speed, Sussex, England on June 23-26. Based on the all-new McLaren Artura luxury supercar, the Artura GT4 builds on the huge successes of the multi-championship-winning 570S GT4 and 720S GT3 competition cars.

The new Artura GT4 shares much of its technology with the all-new McLaren Artura road car, which debuts the McLaren Carbon Lightweight Architecture featuring a carbon fibre monocoque at its core. This motorsport-inspired chassis design and construction is the ideal platform for a race car, as a rigid structure enables a wider setup envelope for the driver as well as providing a strong and extremely safe driving environment.

The minimisation of weight is a key element of the Artura road car, and this philosophy continues in the race car – with a compact V6 engine and ancillaries including the exhaust system all weight-optimised, the new GT4 car is more than 100Kg lighter than the outgoing 570S GT4.

The Artura road car has a hybrid powertrain with an all-new, compact twin-turbo 120-degree V6 petrol engine, allied to an Axial Flux E-Motor located in the transmission. The V6 engine alone generates more than enough output for the tightly-controlled GT4 racing requirements, where regulations do not permit hybrid powertrains. The lack of hybrid components delivers a weight-saving of 130kg on an already super-lightweight car, while the space within the carbon monocoque for the hybrid battery of the road car now houses the fuel cell and ancillary drive system, keeping weight central and low down.

The new V6 engine features fast-responding twin turbochargers situated within the engine vee and the unit has been designed to offer improved throttle response and fuel economy compared to the older M838 V8 used in the 570S GT4, even without electrification. Considerably lighter and smaller than the older unit, the new V6 engine further improves power-to-weight, lowers the car’s centre of gravity and benefits weight distribution.

The V6 engine is controlled by a Bosch Motorsport ECU to fine-tune Balance of Performance management, essential for competing in the GT4 category. The Artura GT4 also features a modular motorsport wiring harness for serviceability, reducing repair times and costs. This interfaces with a motorsport electrical system for enhanced versatility, with the benefit of more robust and variable control systems.

Power is delivered through a seven-speed gearbox with an improved set of ratios optimised for performance and the transmission system has onboard diagnostic software. The unit is not the same as the Artura road car’s eight-speed seamless shift gearbox as this employs the E-motor for reversing; GT4 regulations demand that the car must have a reverse gear.

The Artura road car carries the McLaren design principles of ‘everything for a reason’ and accordingly has high aerodynamic efficiency. The GT4 iteration extends this further with an aerodynamic package that offers greater downforce than the outgoing 570S GT4 particularly at the front end, which features a bespoke splitter, dive planes and bespoke bonnet duct. At the rear a high efficiency wing incorporates seven angle settings to cover a wide spectrum of circuit types.

Track excellence is an important part of the GT4 equation, but the Artura GT4 is designed to race in a category governed by Balance of Performance technical regulations that are intended to equalise a wide range of supercars and GTs with differing chassis layouts, power outputs and weights. Much attention, therefore, has been paid to the accessibility and safety of the Artura GT4 to both drivers and race teams.

Drivers of McLaren Automotive road and race cars have always enjoyed excellent visibility for both placing the car on track and in the intensity of wheel-to-wheel racing and the Artura GT4 further improves upon the 570S GT4 in this regard. Ingress and egress is also better, important for swift driver changes mid-race. Safety levels are on a par with the 720S GT3, including the fixed FIA 8862 spec driver’s seat with adjustable pedals for reach and the steering wheel is also inspired by the GT3 car with illuminated buttons for competition in all conditions at both day and night. The cockpit also features a new Bosch DDU instrument display, with enhanced graphics.

Suspension and handling is enhanced over the 570S GT4 with the front wheel width increased for more grip and less tyre degradation with development carried out in conjunction with tyre partner Pirelli. At the rear a mechanical Limited Slip Differential offers increased grip and performance with the benefit of improved rear brake wear, performance and reduced fuel consumption over the 570S GT4’s Electronic Stability Program system. Damping has also been improved, as has brake cooling efficiency. Driver aids include motorsport-specific Anti-lock Braking and Traction Control systems with adjustment for different grip conditions.

The Artura GT4 has also been built with bespoke motorsport-specific components to enhance performance, durability and serviceability for the extreme conditions of racing at the most demanding circuits. All of these components have been subjected to rigorous assessment to ensure that they have an increased lifing schedule.

Serviceability improvements include a removeable bonnet for ease of access and a 110-litre fuel cell with two motorsport lift pumps and a main pump for increased reliability and performance. The rear wing is mounted to the chassis using a new ‘G-Pylon’ design that means the rear bodywork can be removed without having to dismantle the wing. In the interests of robustness in the heat of battle, the Low Temperature Radiators have been moved inboard while the high-level exhaust system is now solely mounted to the powertrain; sound volume is recorded at 105dB static.

Purchasers of the Artura GT4 will also be able to order from a comprehensive list of options to support a range of competition and track environments. These include the fitting of a passenger seat and harness. Both seats can be specified in a variety of sizes.

Additional driver aids available to purchase include a Tyre Pressure Monitoring System, V-Box telemetry and a Collision Avoidance System radar, and a data pack is available with laser ride height sensors, damper potentiometers and brake Infra-Red sensors. Endurance racing options include additional lights for night racing and a drinks system, while left-hand fuel fill and air jack lance are available for differing pit-lane demands.

“The Artura GT4 is the second race car to be built from the ground-up by McLaren Automotive’s Motorsport division. Based on the revolutionary new McLaren Artura, it represents a significant step up from the outgoing 570S GT4, itself a hugely successful competition car which has achieved many race and championship wins with our customer racing teams. With lighter weight, extremely precise handling characteristics and enhanced durability – as well as the packaging and efficiency advantages and all-round serviceability for mechanics of the new V6 powertrain – the Artura GT4 will set new class standards, as we are already seeing from our extensive test and development programme.”
Ian Morgan, Director of Motorsport, McLaren Automotive

The Artura GT4 will make its global public debut at the Goodwood Festival of Speed on June 23-26, where visitors will be able to see it in action on the hill ahead of its competitive debut. At the wheel will be McLaren Factory Driver Rob Bell, winner of last year’s Timed Shootout Final in the McLaren 720S GT3X.

McLaren Automotive’s motorsport division will continue an intensive test and development programme ahead of the 2023 season when the first customer cars will compete. Customers can register interest in the new Artura GT4 now, through McLaren Motorsport Retailers.

Lotus launches Emira GT4 race car with hot laps at Hethel

2023 Lotu Emira GT4 - Front View

Lotus has unveiled the all-new Emira GT4 race car on the iconic Hethel test track, with a dynamic demonstration of its thrilling performance.

At an exclusive event earlier this week VIP guests were treated to passenger laps of the legendary 2.2-mile circuit with Gavan Kershaw, Director of Vehicle Attributes at Lotus and a former British GT Championship winner, at the wheel.

The culmination of more than 70 years of innovation on the road and track, the Emira GT4 marks the start of an exciting new era in performance GT racing for Lotus. It is the first new model from Lotus Advanced Performance, the bespoke vehicle and experiential division of the business launched earlier this year.

The return to world motorsport is a key pillar of the company’s transformation from a UK sports car company to a global performance car business and brand.

This week’s event follows last September’s announcement that Lotus would create a GT version of the critically acclaimed Emira road car. Order books for the Emira GT4 opened at the time and the car has sold out for the first year of production.

Gavan Kershaw, who has been heavily involved in the development, commented: “We knew we had an excellent starting point for the Emira GT4 because of all the work done to make the road car such a great performer. Showing off the GT4’s dynamic capabilities on the Hethel test track – which has shaped countless race cars and their drivers since Lotus moved to the site in 1966 – is a very special moment for me and all the team involved.”

Almost all modern Lotus road cars have had race-ready siblings and the Emira is no exception. Each Emira GT4 customer will receive a homologated performance machine, hand-built with lightweight motorsport components and equipment to meet the latest safety regulations. The project has been a collaboration with Lotus and RML Group.

The advanced composite bodywork makes the car exceptionally lightweight, and is coupled with Toyota’s race-proven 3.5-litre V6 engine and optimised GT4 aerodynamics derived from the road-going Emira’s advanced exterior design.

Since last September’s announcement, the Hethel-based development team has focused on precision engineering to deliver outstanding dynamics and high-speed stability. Many hundreds of hours of validation work have taken place on the test track, and over the winter the Emira GT4 also headed to Portimão in Portugal for a week. In addition to the better weather, it’s one of the most challenging circuits in Europe, making it the perfect destination to validate aero performance and component reliability.

Richard Selwin, Race Programme Manager, Lotus, commented: “We’re delighted with how the Emira GT4 programme has progressed. We have an appealing spec and a level of performance that’s going to thrill both customers and spectators around the world. I believe in the Emira GT4 we have a car that promises to be more than competitive.”

Simon Lane, Director, Lotus Advanced Performance, added: “Lotus’ commitment to motorsport is world-renowned and is one of the key elements of enhanced customer engagement within this recently launched division of the business. We have exciting plans for Lotus Advanced Performance – there is much more to come.”

Also at Hethel for the Emira GT4 launch event was a Lotus Type 30 sports racer. This white 1965 GT is powered by a Ford 4.7-litre V8, is privately owned and won the Whitsun Trophy at last year’s Goodwood Revival. Only 33 examples of the Type 30 were built and achieved numerous wins in the hands of Lotus legend Jim Clark and others.

Lotus has been synonymous with racing success ever since the Mark I, a trials car hand-built by founder Colin Chapman in 1948, and the company has pioneered many of the technical innovations which make racing the thrilling sport it is today. Lotus’ impressive roll-call of honours includes seven Formula 1 Constructors’ titles, six Drivers’ Championships and victory in the legendary Indianapolis 500.

Most recently Lotus has been racing with the Evora GT4, which won prestigious races and championships including in British GT, Dubai 24hrs, Barcelona 24hrs, European GT, Sepang 12hrs and the Pirelli World Challenge.

2022 Porsche 718 Cayman GT4 RS

Born in Flacht with the genes of a race car, the new 718 Cayman GT4 RS shares naturally aspirated heart with the 911 GT3 making the most thrilling and focused 718 yet.

The naturally aspirated flat-six engine used in the 911 GT3 Cup car and the road-going 911 GT3 represents the heart of this uncompromising driver’s car. The engine revs up to 9,000 rpm. Power increases by 79 hp compared to the 718 Cayman GT4 to a total of 493 hp, resulting in a weight-to-power ratio of 6.55 lbs. per hp. Maximum torque increases from 317 lb.-ft. to 331 lb.-ft.

Accompanying the new engine and significantly enhanced performance are many changes to the appearance of the car, driven by functional demands. Among the many design changes applied to the 718 Cayman GT4 RS are the air intakes behind the side windows on the driver and passenger side where other 718 Cayman models would usually have a small window. The new RS-specific air intakes improve the flow of intake air, which can be clearly heard due to the proximity to the driver’s and passenger’s ears. Side intakes in the rear quarter panels – a long-running design feature of all Cayman models – are still present albeit revised to meet the greater cooling demands of the new engine.

Like every modern RS variant, the new 718 Cayman GT4 RS will be offered exclusively with the seven-speed dual-clutch transmission (PDK): It changes gears with lightning-quick speeds and contributes to the high degree of performance that the car offers. Using shift paddles mounted on the steering wheel, drivers can change gears manually as they choose without taking their hands off the wheel. Alternatively, they can also change gears manually using the newly designed shift lever in the center console.

The Sport-PDK features shorter gearing than what is found in a PDK-equipped 718 Cayman GT4, and contributes to the impressive acceleration. The 718 Cayman GT4 RS accelerates from 0 to 60 mph in 3.2 seconds – half a second quicker than the 414 hp 718 Cayman GT4 with PDK. Top track speed is 196 mph (GT4 with PDK: 187 mph), which the GT4 RS reaches in seventh gear.

In common with its RS model predecessors, the 718 Cayman GT4 RS was constructed with a focus on lightweight materials. The U.S. curb weight is 3,227 lbs. – 49 lbs. less than a 718 Cayman GT4 with PDK. For example the front fenders and hood are formed out of carbon fiber reinforced plastic (CFRP). The rear window is made of lightweight glass. Lightweight door panels with fabric door opening loops and storage nets round off the focus on lowering weight.

The new, fixed rear wing with a swan neck mounts and aluminum supports represents a marked difference to other 718 models, including the GT4. This particularly efficient wing designed was adopted from the Porsche 911 RSR race car and was first used on a Porsche road car on the 2022 911 GT3. Combined with a ride height that is 30 millimeters lower than a standard Cayman, front wheel well ventilation, an aerodynamically optimized underbody with a rear diffusor, an adjustable front diffusor and a new front spoiler lip with flow-around side-blades, the GT4 RS generates up to 25 percent more downforce in the racetrack-only Performance mode than the 718 Cayman GT4.

Enhancements to the suspension also contribute to the even higher level of performance. Ball joints connect the suspension to the body and contribute to an even higher level of precision and responsiveness. The adjustable and track-focused suspension received an RS-specific damper setup as well as revised spring and anti-roll bar rates. Additionally, 20-inch forged aluminum wheels with center locks are used for the first time on a 718 Cayman model.

The optional Weissach Package enhances the performance-focused appearance of the GT4 RS even further. When this option is selected, the front luggage compartment lid, process air intakes, cooling air intakes, air box lid, exterior mirrors caps and the rear wing are made of carbon fiber. Exhaust tips made of titanium are inspired by the exhaust of the Porsche 935/19. The upper part of the dashboard is upholstered in Race-Tex with this option, while the rear window features a large Porsche logo type. Magnesium wheels are available as an addition to the Weissach Package for an additional cost.

The sum of these enhancements compared to the 718 Cayman GT4 make the GT4 RS the most uncompromised and exciting member of the 718 family. Its performance on the Nürburgring-Nordschleife underscore this particularly well. During final testing and evaluation drives, Porsche brand ambassador Jörg Bergmeister completed a lap of the 20.832 kilometer (12.944 mile) track in 7:09.300 minutes. On the shorter track variant, which was formerly used as a benchmark (20.6 km in length), the GT4 RS set a time of 7:04.511 minutes – 23.6 seconds quicker than the 718 Cayman GT4.

To celebrate this impressive car, Porsche Design has created a Porsche Design Chronograph 718 Cayman GT4 RS, which will be offered exclusively to buyers of the vehicle. Like the car itself, the timepiece features a lightweight concept with a performance focused character by using high-tech titanium materials. The winding rotor design takes on visual cues from the wheels of the car and is available in different colors to match the vehicle.

The new 2022 Porsche 718 Cayman GT4 RS is celebrating its world premiere at the Los Angeles Auto Show and has an MSRP of $141,700, not including a $1,350 delivery, processing and handling fee. It is expected to reach U.S. dealers in the course of summer 2022. The racing version 718 Cayman GT4 RS Clubsport is also being debuted in L.A., which will be competing in many national and international racing series next year.

McLaren Announces the Track-Only 570S GT4. Pricing Starts at £159,900

McLaren 570S GT4 Front View McLaren 570S GT4 and 570S Sprint are the two new models dedicated for the track. They are part of the recently-launched Sports Series and were developed in conjunction with McLaren GT. The bigger news is that the 570S GT4 will also enter an intensive season-long development program in the British GT championship. In fact, the McLaren GT and CRS GT Limited will work with the team Black Bull Ecurie Ecosse (which will compete with the aforementioned model alongside the entry of the 650S GT3 with Factory Driver Rob Bell and Alaisdair McCaig) in the full nine round calendar.

The 570S Sprint has been only announced and will be revealed very soon. This one is dedicated for private trackdays and this means that it is unrestricted by any racing regulations. Nevertheless, the 570S Sprint can be upgraded eventually to GT4 specification.

Another announcement made by McLaren Automotive is the confirmation of the new Motorsport Director Ansar Ali, who will be responsible for on-going strategy and management of motorsport activities.

Details About McLAREN 570S GT4

McLaren 570S GT4 Rear View

570S GT4 is track-only and has the carbon fibre MonoCell II chassis architecture just like the other models in the Sports Series. The carbon material will provide not only inherent strength to car’s body but will also make it light in weight. Driver’s protection is secured by the FIA-approved rollcage and fire extinguisher system. Except for the architecture, carbon (and aluminum) has been used for the reprofiled bodywork. Cast magnesium alloy wheels shod with slick Pirelli racing tires carry this exclusives-looking body. Driving dynamics are ensured by the two-way adjustable motorsport dampers with coil-over springs at the front and the rear. The on-board air jacking system is fitted as standard.

The aerodynamic package is a must when it comes to focusing on the laptimes. Therefore the 570S GT4 is fitted with high level rear wing, mounted on aluminium pylons, a larger front splitter and reprofiled floor assembly. There is an additional front centre high temperature radiator, which sits below a GT3-inspired bonnet with radiator exit ducts, optimizing performance and cooling at the same time.

Carried over from the road-going Sports Series model is the engine, which is the 3.8-litre twin turbo V8. It is connected to a seven-speed seamless shift gearbox that drives the rear wheels.

McLaren 570S GT4 will be revealed at the opening of the British GT Championship at Brands Hatch, UK between 16^th and 17^th April. It has a starting price of £159,900. We do expect in the upcoming weeks additional details, pictures and pricing for the 570S.

Maserati GranTurismo MC GT4 to Compete in 2016 GT4 Championships

Maserati GranTurismo MC GT4 Side View Last weekend, we witnessed the final round of the 2015 Trofeo World Series. The motorsport event took place at Abu Dhabi’s Yas Marina circuit, making it the sixth and final season in Maserati’s single-make series to a close. Nevertheless, this isn’t the end of company’s sporting activities. Maserati has just announced that it will be back on track in 2016 with its super hero Maserati GranTurismo MC GT4. The car will be competing at international GT4 series run by private teams.

Basically, Maserati is returning to the GT4 category, after a distant debut in the 2009 European GT4 championship and a positive feedback from three ‘test races’ in 2015, at Road America, Laguna Seca and Misano. And the best part is that we will see Maserati battling on two fronts next season: the European GT4 Championships and the US Pirelli World Challenge.

However, before the start of the motorposrt events, the team must make some necessary modifications on the engine and regarding the aerodynamics. They are obligatory because of modifications required for GT4 homologation.

Maserati GranTurismo MC GT4 Front View

In general, car’s overall technical make-up will remain unchanged. This means that GranTurismo MC GT4 will keep its 4700cc engine, electro-actuated transmission with paddle-shift commands and the kerb weight of 1410 kg.

The change lies in the additional air scoop, which will reduce car’s power output to 430 bhp from its current 488 bhp. In addition, the newly-designed rear spoiler and modified diffuser will contribute towards car’s performance that will match the other GT4 cars. The final set up of the car will be established during the official pre-championship Balance of Performance (BoP) tests where the GT4 SRO homologation standards will be completed.

The company will be tracking the performance of all teams that will be racing in Europe and the USA. What is more, it will also give a special award for the best Maserati driver and team. Now, you can watch the Maserati GranTurismo MC GT4 in a video below.

The Rebel Awakens. Watch the Latest Video of Porsche Cayman GT4 Clubsport

Porsche Cayman GT4 Clubsport Video Screenshot Ten days ago Porsche presented at the L.A. Motor Show its brand new and ecstatic Cayman GT4 Clubsport. Now the luxurious company promotes the car with furious video showing-off the how the sports car behaves in action. There is really nothing much said about it, except for this: “If the rebel inside you dreams of this. Get him on track… Rebels race harder.”

And I really like it because it describes the spirit of the Cayman GT4 Clubsport so well. It is a rebel and according to this video it definitely races harder than anyone else on the track… or? I would like to hear your thoughts of comparison here.

Anyway, the rally car as described by Porsche is the perfect vehicle for ‘recreational and club racing’. It is mid-engined, driven by 3.8-litre flat-six unit, which is positioned behind the driver’s seat. Some sports characteristics are too contributed by the custom six-speed Porsche double clutch with shift paddles on the steering wheel and a mechanical rear-axle locking differential.

Porsche Cayman GT4 Clubsport Beautiful Rear

Porsche Announces Mysterious Geneva Premiere

Porsche will make a double world premiere in Geneva next week. We have seen the first car that is going to be officially presented and it is the Cayman GT4. The second model however is covered in mystery, since there is no word or even a teaser about it. The only thing that the company said is that it will be “another exceptional Porsche” that is destined to bring new standard in terms of performance.

And does this mean that actually the company is enjoying making high-performance vehicles suitable for everyday driving? Inarguably yes! In addition these two debuts speak of something like tradition which Porsche has established. We talk about the fact that it always introduces motorsport-bounded vehicles in Geneva.

Take for instance the 911 GT3 and 919 Hybrid. We have witnessed their birth in the Swiss city in the previous years. Now it is time for the Cayman GT4 to do the same. In fact this is the first high-performance sports car from the GT family based on the mid-engine coupes.

The model already made an impressive Nürburgring track debut by achieving a lap time of 7 minutes and 40 seconds on the North Loop. The main responsibility for this should be attributed to the 3.8-liter engine that has the capability of 385 hp (283 kW) and is a derivative of 911 Carrera S’ unit.

In addition, what differentiates the new Cayman from the others in its family are the new front featuring lowered front spoiler, the additional hood air outlet and the rear wing. These elements all contribute towards better downforce at both axles.

Still, our mind is taken by the thoughts of this mysterious model and we can’t wait to know more about it. Do you have any suggestions?

Kia GT4 Stinger Convertible Concept [render]

X-Tomi Design has published a render picture of Kia GT4 Stinger Convertible Concept. The Korean manufacturer managed to impress the audience at 2014 NAIAS in Detroit with GT4 Stinger Concept.

The Coupe is powered by a T-GDI 2.0 liter engine – 315HP. All of that power is sent to the rear wheels via a close-ratio 6-speed manual transmission. The stopping power is courtesy to the Brembo Gran Turismo 15” crossdrilled rotors and four-piston calipers.

The GT4 Coupe boasts 52:48 weight distribution, the quick-ratio steering rack and its relatively low unsprung mass which stands at 1,303kg (2,874 lbs). Probably the Convertible will be slightly more heavy, but it will still manage to keep the perfect weight distribution.

Kia Reveales Details For GT4 Stinger And Next Teaser Image

A week ago it was announced that Kia will premiere a concept vehicle called GT4 Stinger at 2014 Detroit Motor Show (NAIAS). With this news the brand released a teaser image of the front of the car. Now the world is ready for another portion of the car revealed ahead of official debut.

The teaser shows the car when looked from above with its sleek and dynamic profile. Beneath the low wedge of the sculpted bonnet is hidden a tuned version of Kia’s 2.0-litre turbocharged gasoline direct injection (T-GDI) four-cylinder engine. The latter is responsible for the 315 horsepower (232 kW).

The unit is matched with a close-ratio six-speed manual transmission which directs power to the rear wheels. There 275/35R20 Pirelli P-Zero performance tyres meet the asphalt. The tyres on the other hand are coupled with custom 20-inch aluminium centre-lock wheels with carbon fibre inserts for strength and weight reduction.

What bring to halt the GT4 are Brembo Gran Tourismo two-piece cross-drilled rotors with four-piston callipers. As one can see, the Stinger will be covered with the expressive ‘Ignition Yellow’ paint, and what one can not see is the custom chassis with an independent double wishbone suspension.

Full specifications of Kia GT4 Stinger are to be revealed next week at NAIAS.
