Two years ago, we tracked down a small, independent automaker on the floor of the Geneva Motor Show that promised to deliver a segment-busting supercar to those bored with Lamborghinis and Ferraris. Fast-forward to today and the Tramontana Group seems to have made good on its promise with the unveiling of the Tramontana R Edition.

The R is an evolved version of the standard open-wheel two-seater, packing a Mercedes-sourced 5.5-liter V12 available in either naturally aspirated, 550 hp guise or a twin-turbocharged 760 hp version that dolls out an astonishing 811 lb-ft of torque. The Group claims a 0-100 kph time of 3.6 seconds and a 10.15-second run to 200 kph.

The wheelbase has been shortened by 50mm to improve handling and aerodynamics, and weight is down by 202 pounds to just 2,777 pounds. The R stretches 192 inches from nose to tail, is 82 inches wide and 51 inches tall, and weight distribution is a perfect 50:50 left to right and 42:58 front to rear. Tramontana fitted 20-inch carbon fiber and magnesium wheels at each corner, along with high-performance summer rubber sized 245/40 in front and 335/30 in the rear. 380mm, six-piston Brembos handle stopping duties, while a custom Ohlins suspension allows the R's ride-height to be adjusted between 85 and 135 mm.

The body speaks for itself, as does the exposed carbon fiber interior, which features a chop-top steering wheel, an LCD instrument panel and the controls to the six-speed sequential gearbox. Production will be limited to 12 units per year with a price tag of €385,000 ($495,000), but unfortunately, we won't be seeing it in Geneva next month – the Tramontana R will make its official debut at the Top Marques Monaco show at the end of March.
