Remember the a.d. Tramontana R? The canopied, tandem-seat oddity represented a bold choice in supercardom, a far brasher choice than something from Maranello or Sant'Agata Bolognese, say. The carbon fiber missile debuted back in 2009 and was powered by a V12 sourced from Mercedes-Benz. Available in various tunes, the powertrain was good for up to 760 horsepower – no small sum given that the larger-than-you-think coupe still weighed less than 2,800 pounds.

But now there's a new choice in the a.d. Tramontana stable, dubbed XTR. While no pictures have been released, the Spanish builder has released this set of renderings, along with word that its latest creation will be powered by a new 5.5-liter twin-turbo V12 that will bludgeon its way down the road with 888 horsepower and 678 pound-feet of torque at its disposal. There's also word of a new "ultra-rapid competition gearbox," but no official details have yet been provided on what, exactly it might be.

The mid-engined, rear-drive XTR also looks to have a significantly reworked appearance, including new aero bits, lights, wheels, and so on, but the core airplane fuselage-like construction and cycle fenders remain.

Pricing? Glad you asked. Available later this year, the XTR is expected to command 420,000 euros – around $514,000. Only about a dozen examples are expected to be built per year, but a.d. Tramontana is reportedly working on expanding both its manufacturing capabilities and dealer footprint.
