GT2 RS and GT3 RS

Written by Samantha Barker, Sales Executive

Both vehicles have one very important thing in common: they have been designed by the Porsche Motorsport department to give our driver’s a thoroughbred sports car that can be driven on both the track and the street. For decades, Porsche’s mission has been to build the perfect sports car combined with everyday usability. While both the GT3 RS and GT2 RS have incredible power, they can be driven on the street as well.

In 2016, the 991.1 GT3 RS was released. An unbelievable machine that needed no improvement. Porsche, being the company that they are, continually strive to make the best better. The new GT2 RS and GT3 RS, released only a few months apart, some wonder what some of the similarities and differences are and why Porsche would release two performance-based vehicles that seem similar. I will outline a few of the major items that separate these two vehicles. How can you make such perfect vehicles even better?  Porsche is known for a few things, but one of the most memorable things for many drivers is the handling of their Porsche and their connection to the road.

What can Porsche possibly improve from the GT3 to GT3 RS and GT2 RS models? The new models have been upgraded with a new suspension using metal ball joints instead of rubber bushings. This offers greater stability, precision and handling - allowing Porsche to stay true to their identity. This reduces the body roll and keeps the body and chassis tightly connected throughout. The spring rates have also been increased to further improve handling. Another similarity between the GT2 RS and the GT3 RS is that both vehicles use high-performance tires designed for the ultimate performance on both the track and the road- again, staying true to Porsche’s ultimate mission. 

What is different between the GT3RS and the GT2RS?

The GT3 RS is built off of on the naturally aspirated 4.0 litre flat-six engine on the GT3. The GT2 RS is built off of the 3.8 liter flat-six twin-turbo engine of the 911 Turbo S. The GT2 RS has larger turbochargers, a modified crankcase, different pistons, a new multi-tube air filter, enlarged airducts, larger intercoolers, and a unique water injection system. The water system actually uses distilled water that is stored in a water tank in the “frunk” of the vehicle. Even in extreme conditions, this will allow for consistent performance. The GT2 RS is about 300lbs lighter than the Turbo S since it is not all-wheel drive. It also has a much shorter rear axle ratio than the Turbo S and more carbon fibre bodywork.

Due to the weight and power difference between the vehicles, they also have different calibrations of shock dampening, steering, rear-axle steering, and stability control systems. Both vehicles have different front and rear facias due to the different cooling requirements and exhaust systems. The GT2 RS comes standard with the Carbon Ceramic Brakes while the GT3 RS comes with the grey-cast iron rotors. Available as an option, the GT3 RS can upgrade to PCCB’s.

While both vehicles are incredible machines, they may inspire driver’s differently. Depending on if you’re looking for that raw, natural power, or if you’d prefer a forced induction turbo engine, Porsche has something for everyone.
