When you already make one of the world's finest "driver's cars," how do you top it? If you're Porsche, you give it more of everything. Such is the case with the 911 GT3RS, the ultimate expression of Porsche's GT3 line of street/track weapons. In RS specification, displacement of the normally aspirated flat six increases from 3.8 to 4.0 liters, yielding 500 horsepower. Add a magnesium roof, 918-derived seats and a standard-equipment roll cage, and you have a car that can turn a 7:20 lap of the Nordschliefe straight from the showroom floor. AUTOart's 1:18-scale ABS composite replica of the legendary Porsche 911 GT3RS captures the visceral appeal of the real thing in precise detail. It features accurately rendered front and rear fender vents that help set the RS apart from its more commonplace GT3 brethren, as well as beautifully executed interior trim and road wheels.
