Is it possible to make a great car even greater? According to Porsche, it is. The second generation of one of Porsche’s most acclaimed cars ever – the 991 GT3 RS – has arrived in America, and the first one is here at Exotics Racing in Las Vegas. The first-generation version holds the track record here, so it’s a sure bet the second-generation edition will only be better. How much so? Porsche says the second generation 991 GT3 RS is nearly 10 seconds a lap faster than the first generation around the Nürburgring’s Nordschleife circuit. If there is such a thing as supercar perfection, you can now find it at Exotics Racing in Las Vegas.
