Porsche 911 GT3 RS 2023 Serba Baharu Didedahkan

Versi Prestasi Ultimate Generasi 992 – Porsche 911 GT3 RS 2023.

911 sentiasa menjadi penanda aras untuk prestasi dan keinginan dalam pasaran supercar, tetapi sejak generasi 996, Porsche telah menjangkaui had mereka sendiri. Sejak 2003, ekspresi prestasi muktamad 911 telah ditakrifkan oleh model 911 GT3 RS. Kini terdapat 911 GT3 RS serba baharu berdasarkan 911 generasi 992 semasa dan ia melampaui had dengan lebih jauh.

Varian baharu ini dibina berdasarkan asas 911 GT3, dan telah dipertingkatkan. 4.0L flat 6 yang sama dengan throttle body individu kini mengeluarkan 518hp dan bukannya 502hp. PDK 7-kelajuan mempunyai nisbah gear yang lebih pendek dan mendapat penyejukan udara tambahan dari bawah kenderaan. Kelajuan tertinggi ialah 296km/j dan 0-60mph hanya mengambil masa 3 saat, menjadikannya 0.2 saat lebih pantas daripada 911 GT3.

Piston pada brek mempunyai peningkatan diameter 32mm dan ketebalan cakera brek juga sehingga 36mm. Brek Komposit Seramik Porsche pilihan juga disediakan. Tayar Ultra High Performance dipasang dengan saiz berperingkat untuk cengkaman mekanikal maksimum.

Penyejukan dan aerodinamik juga merupakan bahagian penting dalam peningkatan prestasi 911 GT3 RS. Ia memperoleh sebahagian besar daripada 911 GT3 R yang dioptimumkan untuk sukan permotoran. Perbezaan utama pertama ialah penggunaan radiator tengah bersudut yang besar di hidung kereta dan bukannya ruang bagasi. Ini membebaskan ruang dengan menghapuskan sistem radiator tiga kali ganda dalam kereta terdahulu, membebaskan ruang untuk elemen aerodinamik yang lebih aktif. Ini termasuk sayap berfungsi, termasuk sayap belakang swan-neck-supported dengan hydraulically adjustable upper blade.

Sayapnya lebih tinggi daripada bumbung, yang merupakan yang pertama untuk Porsche pengeluaran. Terdapat juga front splitter, side blades, front wheel arch louvered openings, inlet di belakang roda hadapan, lubang hidung pada penutup hadapan, fin pada bumbung, bukaan di panel sisi belakang, salur masuk gerbang roda belakang, peresap belakang dan banyak lagi. Elemen sayap boleh laras berterusan memberikannya sehingga tiga kali lebih banyak daya ke bawah berbanding 911 GT3 semasa.

Buat pertama kalinya, Porsche telah menggunakan sistem drag reduction. Ia meleperkan sayap dengan menekan butang dan membantu menyeret ke bawah untuk kelajuan yang lebih tinggi. Terdapat juga fungsi brek udara yang menggerakkan sayap untuk memaksimumkan seretan.

MEDIA RELEASE

Track suspension that can be adjusted from inside the car 
Even the suspension is modified for improved aerodynamics. Because the wheel arches of the new 911 GT3 RS are subject to powerful airflows, the components of the double-wishbone front axle are designed with teardrop-shaped profiles. These aerodynamically efficient links increase downforce on the front axle by around 88 lbs. at top track speed and are otherwise only used in high-end motorsport applications. Front track width increases by 1.14 inches (29 millimeters), necessitating longer double-wishbone front axle links. 

To ensure that the downforce balance between the front and rear axles is maintained even when braking from high speeds, the suspension engineers have significantly reduced pitching under braking. On the new 911 GT3 RS, the front ball joint of the lower trailing arm has been set lower on the front axle. The multi-link rear axle has also been adjusted, with modified spring rates. The driver assistance systems and rear-axle steering also have an even more dynamic set-up here.

The 911 GT3 RS offers three driving modes: Normal, Sport and Track. In Track mode, the basic settings can be individually adjusted. Among other settings, the rebound and compression damping of the front and rear axles can be adjusted separately and in several stages. The rear differential can also be adjusted via rotary controls on the steering wheel. This is done quickly and intuitively with an operating and display concept also borrowed from endurance racing. Four individual rotary controls and a button for the Drag Reduction System (DRS) are located on the steering wheel. These rotary controls appear in the instrument cluster during the adjustment process. The 911 GT3 RS also features the track screen already familiar from the 911 GT3. At the touch of a button, the driver can reduce the two seven-inch side displays to essential information only. The gearshift indicator lights to the left and right of the analog tachometer have also been taken from the 911 GT3.

High-revving four liter six-cylinder boxer engine 
The 4.0-liter high-revving naturally aspirated engine has been further optimized compared with the 911 GT3. The increase in power to 518 hp (911 GT3 – 502 hp) is achieved primarily via new camshafts with modified cam profiles. The single-throttle intake system and the rigid valvetrain are derived from motorsport. Like the 911 GT3, this engine also has six individual throttle bodies; one per cylinder. The seven-speed Porsche Doppelkupplung (PDK) has a shorter overall gear ratio than the 911 GT3 and is aided by air intakes on the underbody to ensure that the transmission can withstand even extreme loads during frequent use on track.

The 911 GT3 RS accelerates from 0 to 60 mph in 3.0 seconds (911 GT3 – 3.2 seconds) and reaches a top speed of 184 mph in seventh gear. Six-piston aluminum monobloc fixed-caliper brakes and brake discs with a diameter of 408 mm are used on the front axle. Compared with the 911 GT3, the piston diameters have been increased from 30 to 32 mm. In addition, the thickness of the discs has been increased from 34 to 36 mm. The rear axle continues to be fitted with 380-mm brake discs and four-piston fixed-caliper brakes. The optionally available Porsche Ceramic Composite Brakes (PCCB) use 410-mm discs on the front axle and 390-mm discs on the rear axle. The new 911 GT3 RS also comes standard with forged light-alloy center-locking wheels. Street-legal Ultra High Performance tires measuring 275/35 R 20 at the front and 335/30 R21 at the rear provide a high level of mechanical grip. 

Lightweight construction all the way 
Intelligent lightweight construction has been a basic principle of all RS models ever since the legendary 911 Carrera RS 2.7. Thanks to an array of lightweight construction measures such as the extensive use of carbon fiber reinforced plastic (CFRP), the 911 GT3 RS weighs in at only 3,268 lbs.. The doors, front quarter panels, roof and hood, for example, are made from CFRP. Lightweight CFRP is also used in the interior, including the standard full bucket seats, trimmed in black leather and Race-Tex joining carbon fiber trim throughout the interior to characterize the pure, sporty ambience. 

Available with Weissach package 
The Weissach package, which is available at extra cost, includes a considerable number of changes to the standard vehicle. The hood, roof, parts of the rear wing and the upper portion of the side mirrors housing feature visible carbon fiber. The front and rear anti-roll bars, the rear coupling rods and the shear panel on the rear axle are made of CFRP and contribute to a further enhancement of the driving dynamics. Another highlight of the Weissach package is the PDK shift paddles with motorsport-derived magnet technology. This makes gear changes feel especially precise thanks to a pressure point and a clearly perceptible click. Forged magnesium wheels are included in the Weissach package and save 17.6 lbs of unspring weight compared to the standard wheels.

The 2023 911 GT3 RS is expected to arrive at U.S. dealers by Spring, 2023. The starting MSRP is $223,800 excluding $1,450 for processing, delivery and handling. 

Exclusive Porsche Design Chronograph 
Inspired by the motorsport mindset – where maximum precision is paramount – Porsche’s own watchmaking operation in Solothurn, Switzerland, has developed the 911 GT3 RS chronograph. This mechanical watch is available as an option, and is reserved for owners of the car. It is based on a glass-bead blasted case, made from either natural or black titanium, and with a screw-down crown. Inside the watch is the mechanical Porsche Design chronograph caliber WERK 01.200, which has been COSC-certified for its high accuracy. Its flyback function allows the wearer to start, stop and reset the second hand with a single action. The chronograph pushers, which feature ”Start/Stop” and ”Next Lap” laser engravings, reveal that this chronograph is not just about telling the time. In addition to innovations, such as the pulsometer scale on the bezel, many design features and materials from the GT3 RS are also found.
