The GT3RS, a renowned sports car born from the iconic Porsche lineage, holds within it’s four-liter, naturally aspirated engine an exceptional power that surpasses it’s formidable counterpart, the GT3. While the engine size remains the same, the GT3RS unveils a series of meticulously engineered improvements that contribute to it’s increased horsepower. Beholden to the pursuit of automotive excellence, Porsche's engineers have crafted new cylinder heads with a particular focus on circumventing oil entrapment during high-G corners. Additionally, the GT3RS boasts fresh camshafts that bestow heightened lift at the upper echelons of it’s rev range, resulting in an elevated power output of 518 horsepower. This amplified performance not only propels the GT3RS beyond the capabilities of the GT3 but also showcases Porsche's unwavering commitment to pushing the boundaries of automotive engineering.

What Is Special About the GT3?

The GT3 is a racing car that stands out for it’s exceptional performance and capabilities on the track. It’s governed by the Group GT3 regulations, which ensure consistent and competitive racing across different series and championships worldwide. These regulations are maintained by the Fédération Internationale de lAutomobile (FIA), the governing body of motorsport.

One of the standout features of the GT3 is it’s powerful naturally-aspirated 4.0-liter flat-six engine. This engine is capable of reaching an astonishing 9,000 rpm, generating an impressive 502 horsepower. This high-revving engine is a true joy for drivers, delivering exhilarating acceleration and an intoxicating soundtrack.

In addition to it’s formidable engine, the GT3 RS variant takes performance to another level. One of the standout features of the GT3 RS is it’s wild race-car aerodynamic components. Taking inspiration from GT and Formula 1 race cars, these aerodynamic elements enhance downforce and overall performance, allowing for higher speeds and improved handling on the track.

The GT3 isn’t only a powerhouse on the straights but also excels in the corners. It’s advanced suspension setup and aerodynamics enable it to tackle corners with precision and confidence.

Another aspect that sets the GT3 apart is it’s attention to detail in terms of engineering and technology.

It’s race-inspired design, powerful engine, and advanced technology make it a true standout in the world of grand tourer racing cars.

The Turbo S’s superior speed compared to the GT3 RS can be attributed to a combination of factors. Despite the GT3 RS’s impressive performance capabilities with it’s sharp and naturally aspirated flat-six engine, two-wheel drive, and reduced weight, the Turbo S holds an advantage with it’s four-wheel drive system, raw power, and secure handling. These elements allow the Turbo S to dominate the road, making it faster than it’s GT3 RS counterpart.

Why Is Turbo S Faster Than GT3 RS?

The comparison between the Porsche 911 Turbo S and the GT3 RS boils down to a battle between raw power and pure athleticism. While the GT3 RS relies on it’s sharp, naturally aspirated flat-six engine and lightweight body to effortlessly navigate the race track, the Turbo S employs a different approach.

The Turbo S is armed with four-wheel drive, providing increased traction and grip on every turn. This, combined with it’s immense power output, allows the Turbo S to rocket off the starting line and maintain maximum speed throughout the entire race.

Furthermore, the Turbo S boasts something the GT3 RS lacks – forced induction. The twin-turbocharged engine of the Turbo S delivers immense levels of torque and power, allowing for blistering acceleration that leaves it’s competitors in the dust.

Porsche engineers have finely tuned the suspension and aerodynamics of the Turbo S to ensure it remains stable and planted, even at high speeds. This allows drivers to push the limits with confidence, knowing that the Turbo S will stick to the road like glue.

The Turbo S takes the crown as the faster vehicle due to it’s combination of four-wheel drive, raw firepower, and secure handling.

While both the Porsche GT2 RS and GT3 RS are renowned performers on the track, the GT2 RS surpasses it’s GT3 counterpart in terms of speed and power. This is primarily due to several key factors, including larger turbochargers, a distinct crankcase, unique pistons, large air ducts, intercoolers, and a special water injection system. With an impressive output of over 700 horsepower, the GT2 RS outshines the GT3 RS’s 500+ horsepower, making it a force to be reckoned with on the road. Furthermore, the weight of these models differs, contributing to the GT2 RS’s ability to accelerate faster and achieve even greater speeds.

Why Is the GT2 Faster Than the GT3?

The GT2 RS is lighter than the GT3 RS, thanks to the extensive use of carbon fiber reinforced plastic (CFRP) components. These lightweight materials are utilized in the body panels, front hood, rear wing, and interior, contributing to a significantly reduced overall weight. Additionally, the GT2 RS features a stripped-down interior, with features such as air conditioning and sound insulation being removed to save weight.

Another factor that contributes to the GT2 RS being faster than the GT3 RS is the aerodynamics. Porsche engineers have worked extensively on fine-tuning the aerodynamics of the GT2 RS to minimize drag and maximize downforce. This includes a revised front fascia, an adjustable rear wing, and a rear diffuser. These aerodynamic enhancements result in improved stability and cornering performance at high speeds.

The suspension system of the GT2 RS is also optimized for high-performance driving. Porsche equipped the GT2 RS with a specially calibrated PASM (Porsche Active Suspension Management) system, which allows for precise adjustment of the suspension to suit different driving conditions. This, combined with the rear-wheel-drive setup and wider track, enhances the handling and agility of the GT2 RS.

Furthermore, the GT2 RS features a rear-wheel-drive system, whereas the GT3 RS is equipped with an all-wheel-drive system.

The duPont Registry test shows that the GT2 RS outperforms the GT3 RS in terms of horsepower and top speed. With 700 HP and a top speed of 211 MPH, the GT2 RS surpasses the GT3 RS’s 520 HP and 193 MPH limit. But does this mean the GT2 RS is faster in other aspects too? Let’s find out.

Is GT3 RS Faster Than GT2?

According to the duPont Registry, the GT2 RS is indeed faster than the GT3 RS. This discrepancy in speed is primarily due to the significant difference in horsepower between the two models. While the GT3 RS boasts a respectable 520 horsepower, the GT2 RS takes it up a notch with a staggering 700 horsepower.

With such raw power at it’s disposal, the GT2 RS has no trouble accelerating to higher speeds. It’s a top speed of 211 MPH, leaving the GT3 RS in the dust with it’s 193 MPH limit. This means that the GT2 RS can unleash it’s full potential on the racetrack or open highways, achieving incredible speeds that would be out of reach for the GT3 RS.

It can go from 0 to 60 MPH in a mind-boggling 2.7 seconds, showcasing it’s incredible performance capabilities. On the other hand, the GT3 RS achieves a respectable 0 to 60 MPH time, but it falls slightly behind it’s more powerful sibling.

However, both models offer exceptional performance and driving experiences, ensuring Porsche enthusiasts have a variety of options to choose from based on their preferences and driving style.


In conclusion, the Porsche GT3 RS stands out as a fierce performer, surpassing it’s GT3 counterpart in raw horsepower thanks to meticulous engineering refinements. Despite both models sharing the same 4-liter naturally aspirated engine, the GT3 RS differentiates itself through innovative modifications such as specifically milled cylinder heads that prevent oil entrapment during intense high-G cornering. These meticulous advancements exemplify Porsche's unyielding commitment to pushing the boundaries of performance, allowing enthusiasts to experience the exhilaration of true driving mastery.
