Model developed based on 992 type Porsche 911
The new Porsche 911 GT3 R has been announced to be unveiled to the public at the Spa-Francorchamps 24 Hours race this year (2022).
This is so cool that I fell in love with it at first sight~ (Of course, for those who want to watch the game, not the desire to own it)! !
I am writing this article just because I want to post the photos on this blog because they are so cool just looking at them (laughs).
What is the new Porsche 911 GT3 R?
I would like to briefly see what kind of car the Porsche 911 GT3 R was written:
- Development started in 2019
- Developed based on the 992 type Porsche 911
- NA horizontally opposed 6-cylinder engine with 4.2-liter water-cooled 4-valve technology and gasoline direct injection engine
- Especially the newly developed place is the displacement. Like the 911 RSR, the displacement of the new 911 GT3 R has increased by 5% from 3,997cc to 4,194cc.
- Along with the increase in displacement, the maximum output is 565 horsepower (PS). Featuring more stable aerodynamics and vehicle balance
- Optimized torque and power curves across the entire rev range
The new Porsche 911 GT3 R is slightly tilted forward
- The engine is in the classic rear position, which enhances traction and braking. However, the front of the vehicle is tilted forward by 5.5 degrees, giving the underbody diffuser more room.
- Auxiliary units such as the alternator and air conditioner compressor have been moved to the space in front of the engine and gearbox → Good effect on the weight balance of the 911 GT3 R
- The 6-speed gearbox is derived from the current Porsche 911 GT3 Cup
- Paddle shifters control electronic shift drum actuators, allowing very quick and precise gear changes
- The suspension has taken many components and technical solutions from the '911 RSR and changed many details.
- Double wishbones on the front axle and multi-link design on the rear axle
- KW shock absorber is further improved and can be set in 5 steps, using shims / Shims to set up
- Improved and better placement of the central pivot point on the front axle creates space for the aerodynamic 'race underfloor' concept
- Similar to the 911 RSR, the raised underbody allows air to flow cleanly to the rear diffuser, reducing the pitch sensitivity of the racing car = increasing the rake when braking.
- The rear tire has been moved slightly back, and the wheelbase has been increased from 2,459 mm to 2,507 mm.
- In addition to aluminum monobloc racing brake calipers, brake discs from specialist company AP will also be supplied.
- Front steel disc 390mm diameter, 6 pistons
- Rear 4-piston caliper with 370mm disc
- Well-crafted software for 5th generation racing ABS reduces tire and brake wear
- Improved traction control system
- Although the body has been significantly modified for the 911 GT3 R, it is a lightweight body using a composite material of aluminum and steel based on the production model.
- Nearly all bodywork including front and rear hoods, doors, side panels, rear wing and roof are made from lightweight carbon
- Wheel arches made of aramid fiber
- Swan neck rear wing
- Increased safety
- The seat has been moved closer to the center of the car, making the ergonomic seat position compatible with the new FIA side crash protection along with the improved roll cage.
- Like its predecessor, the steering wheel and pedals are vertically adjustable to suit the driver
- The 6-point seat belt has also been reviewed, and designed to slide faster enough to save about 1 second during pit stops for driver changes.
- The steering wheel has also evolved further from its predecessor, incorporating elements proven in the latest 911 GT3 Cup and 911 RSR.
- The 10.3-inch display is derived from successful one-make cup racers and uses the multi-switch concept adopted from Le Mans class winners
- High-performance LED headlights rely on collimator technology developed for LMDh 963 prototypes and others to illuminate a wide area of the circuit.
I've written about it briefly, but anyway, I'm already tired of it just by looking at it, and if the performance is as amazing as it's written here, I don't know how to express it, it's too wonderful. .
If possible, I would like to see this GT3 R running in front of me. I wonder if the day will come when I can do that.
By the way, the price of this new Porsche 911 GT3 R currently announced by Porsche AG is "511,000 euros (about 69.6 million yen)" (actually this price + tax + option fee).
