The Pagani Huayra is an exotic and exclusive Italian roadster worthy of every superlative. You need more than $3 million to buy one. And now there’s a new Huayra R exclusively designed for the track and limited to 30 units globally. The heart of this wicked machine is a naturally aspirated V12 engine with a redline of 9,000 rpm. It delivers 838 horsepower and 553 pound-feet of torque.
