2018 Porsche 911 GT3 VS 2018 Porsche 911 GT2 RS

2018 Porsche 911 GT3:
The 911 GT3 is pure Porsche. It bridges the gap between motorsport and road driving, truly reflecting the core of the brand: successful on the race track, reliable in daily life. The new Porsche 911 GT3 strikes the balance like almost no other. This is all thanks to the completely new, six-cylinder naturally aspirated engine with 368 kW (500 hp), the high-speed engine concept, the revised chassis with near-motorsport tuning and the systematic lightweight construction. With a four-litre flat engine, the 911 GT3 generates its power using the same engine as the thoroughbred 911 GT3 Cup racing car. Developed on the same test track and manufactured on the same production line as the racing car, Porsche's motorsport technology has once again been incorporated into a road-approved sports car. As a result, Porsche's most successful GT sports car delivers an emotional mix of high performance and unfiltered driving feel. The majority of GT drivers also like to take their sports cars for a spin on the race track, which is where the new Porsche 911 GT3 really comes into its own thanks to a weight-to-power ratio of 3.88 kg/kW (2.86 kg/hp). With a seven-speed double-clutch transmission (PDK) that has been specifically tuned for the GT3 as standard, the two-seater weighs in at 1,430 kg with a full fuel tank and can accelerate from 0 to 100 km/h in 3.4 seconds. It boasts a top speed of 318 km/h. For those who love pure unadulterated driving, Porsche also offers the 911 GT3 with a six-speed sports manual gearbox. This allows the high-performance 911 to sprint from 0 to 100 km/h in 3.9 seconds and reach a top speed of 320 km/h...

2018 Porsche 911 GT2 RS:
The fastest and most powerful road-approved 911 is ready for launch: The new Porsche 911 GT2 RS celebrated its world premiere at the 2017 Goodwood Festival of Speed in the UK. At the heart of this high-performance sports car is a 515 kW (700 hp) biturbo flat engine. Weighing in at 1,470 kg with a full fuel tank, the lightweight two-seater accelerates from zero to 100 km/h in 2.8 seconds. The rear-wheel drive Coupé has a top speed of 340 km/h, and with its near-motorsport drive technology, the new Porsche 911 GT2 RS trumps its 3.6-litre predecessor by 59 kW (80 hp) and achieves a torque of 750 Newton metres (an increase of 50 Nm). The engine builds on that 3.8-litre in the 911 Turbo S at 427 kW (580 hp). In order to increase performance, large turbochargers push an increased volume of process air into the combustion chambers. A new additional cooling system delivers optimum cooling at peak loads and, at very high temperatures, sprays the charge-air cooler with water. This causes the gas temperature to fall in the overpressure range and ensures optimum power output, even under extreme conditions. The customised GT seven-speed double-clutch transmission (PDK) in the new GT2 RS enables power to be transferred with uninterrupted traction. What's more, the specially developed exhaust system is made from extra-lightweight titanium, weighs around seven kilograms less than the system used in the 911 Turbo and delivers an emotional sound without precedent. For the first time ever, Porsche Design is celebrating the debut of the high-performance sports car by releasing a special-issue watch. Offering a nod to the world of motorsport, the Porsche 911 GT2 RS watch is exclusively available to owners of the new vehicle and can only be ordered in conjunction with the new GT model at a Porsche Centre from June 30, 2017...
