Four days post this past Thanksgiving on a chilly and cloudy day in Monterey, California, our pro racer Randy Pobst lapped an Ultraviolet GT3 RS around MRLS in just 1: That's seconds quicker than the Turbo S. (Looks like the forecast should've been for purple rain.) Surprised? We were. Sure, the GT3 RS is the most track-focused 911 to date, but the Turbo S is no slouch, either. Moreover, the Turbo S is rated at 560 horsepower and 516 lb-ft (the new '17 gets bumped to 580 hp) and had all-wheel drive and optional Dunlop Sport Maxx Race rubber from the standard GT3. Should it have been more than seconds slower than the 500-horsepower, 338-lb-ft rear-drive RS, which, granted, weighs about 400 pounds less but has the same carbon-ceramic brakes and slightly wider and possibly stickier Michelin Pilot Sport Cup 2 tires? To the Turn 1, the more powerful Turbo S holds a slight lead, registering a top speed of mph versus the RS' But as they enter the long, sweeping Turn 2, the RS closes the gap. At the first apex of the turn, the RS outgrips the Turbo S ( g versus creating an 8-foot advantage. But the Turbo S manages to carry more speed through the turn (minimum of mph versus the GT3's and catches the RS at the exit. That's the last time the Turbo S would ever be RS stomped the Turbo S by seconds at of 2 and toward Turn 3, Pobst is able to accelerate earlier and harder in the RS, posting a speed of mph, noticeably faster than the Turbo S' By the midpoint between Turns 3 and 4, the RS is already 84 feet ahead. Coming into Turn 5, the RS has nearly doubled its lead—now to 150 feet—thanks to a better exit out of 4 and a speedier blast down the straight ( mph versus Around Turn 5, the RS once again outgrips the Turbo S ( g versus extending its lead another 10 feet by the midpoint to 6. From Turns 2 through 6, we see a similar dynamic, with the RS' data line resembling a V and the Turbo S' a U, showing that the RS exhibits very little mid-corner steady-state cruising compared to the Turbo S—just brake, turn, and go. "The RS is rather loose and requires immediate power to help stabilize the rear," Pobst says. "Braking and acceleration are separated. The Turbo S is better balanced and more comfortable to lean on mid-corner, so it can blend braking and acceleration more."A big lat-g advantage through Turn 6 ( g versus helps the RS launch out of the corner earlier and with more oomph. Despite heading uphill toward Turn 7, the comparatively torque-deficient naturally aspirated RS ups its lead to 212 feet over the Turbo S. Down the infamous Corkscrew, the RS stomps the Turbo S, testing director Kim Reynolds says when it posts a cornering speed more than 6 mph faster ( versus The stomping continues through Turns 9 and 10—each a high-speed, high-g endeavor—where the RS is able to accelerate sooner, corner harder, and just go faster. The stats for the last corner, the sharp left Turn 11, show the cars behaving similarly with negligible separation in lateral acceleration and cornering speeds, but the RS is so far ahead that it reaches the finish line some 350 feet and seconds before the Turbo S."The RS is very track-oriented and feels it," Pobst says. "Light, quick, and responsive. The Turbo S is very capable on track, but it's more street-oriented—softer suspension, more body roll, a lot more mass—and feels like it. The speed difference comes from significantly greater agility of the RS, though the better-balanced AWD Turbo S was far easier to drive at the limit."2014 Turbo S: 1: 2016 GT3 RS: 1: More Kiinote columns:Growing Gains: Benchmark Compacts Go Big, Get Better 5 for '15: A Handful of Great Rides from 2015 Downsizing Hits an Upswing: Smaller Turbo Engines Are Going Big A Tale of Two Top Tens: Japan and Make, Buy Very Different Vehicle

Porsche's latest 911 GT3 RS takes on a maxed out Nissan GT-R in a track and road battle. The GT-R’s hand-built twin-turbo isn’t as characterful, yet it’s brutally effective, giving 0

The History and Key Differences Between Them The GT2 RS and GT3 RS are two Porsche 911 models designed with a simple yet compelling premise in mind: a powerful sports car that can also be taken on regular roads. Porsche calls each a “thoroughbred sports car” in the sense that each came from long lines of distinguished and highly capable sports car models Both are undoubtedly dream machines for any motorsport enthusiast. While these two cars may look superficially similar, they differ substantially in power, character, performance, and cost. This article will go over the origins and key differences between the GT2 RS and GT3 RS. A GT2 RS and GT3 RS, both with the Weissach package. Source: YouTube. CLICK HERE FOR A VIDEO REVIEW OF THE GT2 RS AND GT3 RS WEISSACH PACKAGES. A Brief History The Original GT2 Let’s start with the GT2. Named after the Group GT2 (Grand Touring Cars) racing class of the FIA, this car was built with racing in mind. As a high-performance sports car made by Porsche from 1993 to 2009, the GT2 was initially based on the 911 Turbo and used an analogous twin-turbo engine. Despite these core similarities, the GT2 included a smorgasbord of upgrades such as larger brakes and suspension recalibration. The original 993 generation GT2. Photo courtesy of The Car Spy. Source: Wikipedia. The original 993 version of the GT2 ditched many of the unnecessary components of the Turbo and thus was quite a bit lighter overall. It had widened plastic fenders and a large rear wing with air scoops for improved engine cooling. Its original engine generated a maximum power of 316 kW, or 444 horsepower. It could hit a top speed of 187 MPH and go from 0 to 60 in seconds. The 996 model came out in 1999 and, unlike its predecessor, was envisioned first and foremost as a road car. The new GT2 featured a twin-turbo version of the GT3’s flat-six engine (see below). It had a maximum power output of 350 kW (476 hp). The body also witnessed several changes from the previous 993 model. Major differences included wide fenders, a sharper, more aggressive nose, and a larger rear wing. The 996 GT2.

The Original GT3 The GT3 was first introduced in 1999 as a homologation model of the ever-popular Porsche 911, specifically the Porsche 996 model range. Like the GT2, the GT3 was named after the class from the FIA. Also like the GT2, the GT3 was focused on racing and eliminated any items or features that added unnecessary weight to the car. Gone were the rear seats, sound dampening, rear loudspeakers, sunroof, and air conditioning. In came a new flat-six engine design based on units used in the 911 GT1 race car. The engine became known as the Mezger after its chief designer, the engineer Hans Mezger. The original GT3, made from 1999 to 2005. Photo courtesy of Alexandre Prévot from Nancy, France. Source: Wikipedia. Although the Mezger is very similar to the completely water-cooled 962 engines, except that the GT3 engine uses two-cylinder heads each covering a battery of three cylinders. Interestingly, because the air-cooled crankcase has an engine-to-transmission mounting flange configuration, the 996 GT3 used six-speed manual gearbox that was also inherited from the air-cooled 911. Because this gearbox had interchangeable gear ratios and was more durable overall, it was better suited for racing than the standard 996 type of gearbox. The GT3 also featured enlarged brakes, a lowered and retuned suspension system, lighter wheels, and a special front bumper with rear spoiler to bolster downforce and increase overall grip. The sum total of all these features made the GT3 one of the best track cars Porsche had produced up until that point. Source: Road & Track. The GT3 RS In 2003, Porsche introduced the first 911 GT3 RS, a somehow even more racing-focused version of the 996 GT3. The “RS” stands for RennSport, or “racing sport” in English. Notable improvements over the original GT3 included aerodynamic body enhancements, carbon fiber parts, and a magnesium rooftop. The GT3 RS possesses a flat-six engine with 520 HP. Just as interesting are its optional Porsche Ceramic Composite Brakes (PCCB), which are extremely heat and fade resistant compared to typical cast iron units included as factory standard. The GT3 RS (with the Weissach Package), released in February 2018. Source: Despite all these extra features, the GT3 RS is slightly lighter than the GT3 thanks to a polycarbonate rear window, a carbon fiber hood, and a rear wing for reduced drag. The GT3 RS came out in 2016. Since then, Porsche has continued to release new, facelifted GT3 RS models ever since, the most recent being an update of the GT3 in 2018. Additionally, the GT3 RS has a number of different engine specifications from the GT3. For the purposes of racing homologation, the cylinder heads of the GT3 RS have reshaped intake and exhaust ports. It has progressive, rather than linear, springs, and the dampers are somewhere between 10 and 15% stiffer than the GT3. Wheel carriers are made to maximize dynamic control, while the suspension top mounts can be turned 120 degrees. One result of all this is that the GT3 RS is about a tenth of an inch lower to the ground than the GT3. The GT3 RS can accelerate from 0–60 MPH in seconds and has a top speed of 190 MPH. Sources: EVO. The GT2 RS In 2010, Porsche introduced the first GT2 RS to the world. Whereas the GT3 RS was produced alongside the original GT3 for several years, the GT2 wholly replaced the GT2 when it came out. Both lighter and stronger than the original GT2, the GT2 RS engine generates a power output of 456 kW along with 700 N⋅m of torque. The original 2010 Porsche 911 GT2 RS.

With a L twin-turbo flat-six engine, the 991 GT2 RS has a maximum power output of 515 kW, or 691 hp, along with 750 N ⋅ m of torque. This version of the GT2 RS holds the distinction of being the most powerful production 911 variant Porsche has ever built. Because it does not have all-wheel drive, the GT2 RS is also about 300 lbs. lighter than the Turbo S it was originally based on. In order to minimize weight, the GT2 RS incorporates a titanium exhaust system, carbon-ceramic brakes, rear-axle steering, and a stability and traction control program. The Porsche 991 GT2 RS.

In 2017, Porsche test driver Lars Kern used a 911 GT2 RS to set a 6 minute, second record time around the Nürburgring Nordschleife, with an average speed of MPH. A GT2 RS holds the record for the fastest production lap eve recorded, coming in at 3 minutes, seconds around a km track. This record was set in 2018 by Warren Luff, an Australian race and stunt driver. The 2019 Porsche GT2 RS is, as far as we can determine, the fastest street-legal car available right now. It goes from 0 to 60 MPH in seconds. Sources: Auto Express; Porsche; Bring a Trailer. Differences between GT2 RS and GT3 RS We spoke to several customer service representatives from Porsche. They told us that the difference between the GT2 RS and GT3 RS can be summarized in one word: speed. The GT3 RS is renowned for its mix of speed, handling, performance, and feel. The GT2 RS, on the other hand, pushes the speed envelope as far as Porsche cars can possibly go. Another thing to note is each car’s limited availability. “These two models are limited productions,” one agent noted. “The GT3 is only available every 4 years, whereas the GT2 is available every 7-8 years.” Additionally, “the GT2 RS will only be available once during that model’s lifespan.” This article will primarily discuss the latest versions of the GT2 RS and GT3 RS, released in 2017 and 2018 respectively. Engines The key difference between the GT2 RS and GT3 RS, our sources told us, lies in the core engine each one is built off of. They share many of the same design elements and both are great for road or track use. However, the GT2 RS takes those elements and combines them with its powerful twin-turbo engine. The GT2 RS uses a flat-six twin-turbo engine inherited from the original 911 Turbo S. The GT3 RS, on the other hand, is built with a naturally aspirated 4-liter flat-six engine. It uses a VarioCam system that constantly alters the timings of all four cams. This allows the engine to maximize all 22 lbs. of its boost. The flat-six twin-turbo engine used in the GT2 RS. Source: duPont Registry. What this means is that the GT2 RS produces 700 HP compared to the 520 HP of the GT3 RS. The GT2 RS can hit a top speed of 211 MPH, compared to the 193 MPH limit of the GT3 RS. This allowed a GT2 RS to complete the legendary Nürburgring lap a full 10 seconds faster than its GT3 RS competitor. The GT3 RS, in contrast, is all about performance. With its standard PDK transmission, performance-tuned suspension system, carbon ceramic brakes, and multiple aerodynamic enhancements, the GT3 RS exhibits fantastic handling in every way. However, be aware that the GT2 RS does not allow for either all-wheel drive or 4-wheel drive. This may be a serious concern for some drivers who demand stability and grip in their cars. The lack of AWD or 4WD has led the duPont Registry to call the GT2 class “the modern Widowmaker.” Take that information as you will. Most people agree that, while the GT2 RS possesses raw (at times frightening) power, the GT3 displays superior handling and makes for a better track car overall. Other Features: Cooling, Shock Dampening, Calipers, Brakes, etc. Compared to the GT3 RS, the GT2 RS has larger turbochargers, a modified crankcase, different pistons, a special kind of multi-tube air filter, large intercoolers, enlarged airducts, and a water injection system. All this means that, even in the most extreme conditions, the GT2 RS will turn in a reliable performance. As you can see, there is quite a power difference between these vehicles. For this reason, they also have differently calibrated shock dampening, steering (both axles), and stability control systems. Our sources especially wanted to emphasize the larger brakes on the GT2 RS, which have a caliper “about 10 mm bigger” than the GT3 RS. Further, whereas the GT2 RS comes standard with carbon ceramic brakes, the GT3 RS uses cast iron rotors. However, “the 3 brakes are slightly smaller at 380 mm in diameter.” Price We should, of course, mention the cars’ relative price ranges. According to our sources, “The [GT3 RS] will usually be around 300 thousand whereas the [GT2 RS] will be about half a million” in price. Take the latest versions, for example. The latest version of the GT2 RS has an MSRP from about $293,200. The GT3 RS, on the other hand, starts at around $187,500. It’s up to you to decide if the extra speed and raw power of the GT2 RS is worth the extra hundred grand. Weissach Package Before concluding, we should mention the Weissach Package that is optional for both GT2 RS and GT3 Rs. The WP, originally devised for the Porsche 918 Spyder, grants extra engine power and reduces the weight of a car by about 40 lbs. The package comprises of anti-roll bars on front and rear axles, coupling rods and roof both made of carbon-fiber reinforced plastic, and optional forged magnesium wheels. It includes a bolt-in roll cage made of titanium, which, as we all know, possesses the best strength-to-weight ratio of any metal. This makes it approximately lbs. lighter than the steel roll cage. If that weren’t enough, the ultra-light gearshift paddles and the steering wheel trim are also made of carbon-fiber reinforced plastic with a carbon-weave finish. They even made the carpet trim lighter. It would be safe to assume that the GT2 RS with the Weissach Package is hands-down the lightest and fastest Porsche ever conceived. Source: Sources: Porsche; Conclusions So, in conclusion, the GT2 RS is about pure speed, whereas the GT3 RS is about balancing speed with exquisite performance. If you’re need for speed is absolutely unquenchable, the GT2 RS could be the car for you. But if you want smooth handling and control while still easily achieving white-knuckle speeds, give the GT3 RS a try.

Is this the greatest Porsche drag race of all time? You know what, we think it just might be! We’ve got the new Porsche 911 Turbo S facing off against a new 911 GT3 and a 991 generation GT2 RS! And of course, as you’d expect, the stats on all three cars are absolutely wild… Starting with the 911 Turbo, it’s powered by a twin-turbo flat-six that puts down 650hp & 800Nm. Of course, it’s super expensive, costing around £165,000, and it’s also pretty heavy, weighing in at 1,640kg. Alongside it, we have the awesome GT2 RS. It’s also powered by a twin-turbo flat-six, but it puts down 700hp & 750Nm. It’s a fair bit lighter than the Turbo S, at 1,470kg. However, it’s got one big disadvantage – it’s RWD only! It’s also SUPER expensive these days, costing you around £300,000! Then finally we have the GT3. It’s powered by a 4-litre naturally-aspirated flat-six that delivers 510hp & 470Nm. It’s the lightest car here, at 1,435kg, and it’s also the cheapest, at £128,000. But just like the GT2 RS, it’s also only equipped with RWD! So what do you think, will it be a walkover for the Turbo S? There’s only one way to find out… LET’S RACE!
