Pagani Huayra R adopts a naturally aspirated V12 and track-only status — autoblog.com

There’s a new Pagani on the block. It’s called the Huayra R, and it’s a track-only version of the regular Huayra. However, leaving it at that wouldn’t do the Huayra R justice, because it’s so much more than just a hotted up Huayra. The big news is the new and bespoke, naturally aspirated 6.0-liter V12 engine sitting behind the cockpit, a significant departure from the twin-turbo variant used in road-legal Huayras. The new engine was put together by Mercedes-AMG’s racing subsidiary, HWA. The Huayra R makes a furious 850 horsepower and 553 pound-feet of torque. Redline is a scorching 9,000 rpm. Since it didn’t need to follow any road emissions regulations, the engine could be pushed to much higher limits. The Inconel exhaust has removable mufflers for when you want to be extra loud, but can be put in place for use at race tracks with noise restrictions. Unfortunately, Pagani doesn’t quote any specific acceleration figures for the Huayra R.
