Hardcore is use lightly used when calling a Porsche 911 GT3 hardcore or a 911 Turbo GT2 hardcore. Why? Because Porsche comes out with a 911 GT3 RS which is way more hardcore than 911 GT3 and same goes with 911 Turbo GT2 RS. The RS signifies the ultimate race modded from factory that is street legal. Now comes to Dodge Viper. They two variations of the Dodge Vipers and then they came out with a power track ready Viper TA. Well that is pretty hardcore considering it has a huge V10 naturally aspirated motor built for track as well. Nope! Dodge or SRT comes out with Viper ACR (American Club Racing). This is what hardcore is.
