The ultra-exclusive Reventón supercar, with its aggressive stealth fighter looks, leads out Lamborghini's sports car display in Tokyo this week, with just one example of this breed being destined for a Japanese customer. The 340 km/h Reventón was unveiled at the Frankfurt IAA last month, and the Tokyo Motor Show represents only its second worldwide appearance.

Along with its main Italian rivals, Ferrari and Maserati, Japan is a very important market for the Bologna Sant'Agata based sports car makers and its sales are booming. And just like its rivals, Lamborghini has a comprehensive line-up of its cars at the 40th Tokyo Motor Show. This year it expects to sell between 150 and 160 of its models, split up between the V10-engined Gallardo and the range-topping 34 million yen V12-engined Murciélago.

Carlo Zambotto, the head of Lamborghini Japan, introduced the Reventón supercar, which took just under a year to develop, and revealed that one of the 20 examples set to be made was destined for a Japanese owner. With its sales climbing rapidly, Zambotto was upbeat about the long-term future of the brand in Japan.

Named after the bull that killed toreador Felix Guzman in 1943, the Reventón’s interior and exterior styling was inspired by the US military’s F-22 Raptor fighter jet, the latest generation of developed fighter aircraft to utlilise stealth technology. Mechanically this street-legal fighter certainly shows a different route from the generally more environmentally and technical-oriented launches from the Raging Bull’s Italian and German counterparts. Despite this, the Lamborghini Reventón has limited competition, as its price tag of $1.000.000 excluding taxes places it in the extreme leagues of exclusivity. What is more, all 20 of this limited edition beast have been sold, with less than half consigned to orders in the States.

Beneath its edgy carbon fibre composite bodywork, the Reventón packs the unmodified mechanicals of the Lamborghini LP640. The engine is therefore the tried and tested twelve-cylinder with 6.5 litre displacement. At 8000 rpm, the power reaches an astounding 640 hp (471 kW). The huge torque, equal to maximum 660 Nm, ensures a powerful switch from any number of revolutions: even the slightest pressure on the accelerator is spontaneously transformed into thrust. The robotized e-gear changes gear faster than even the most expert driver. In addition, the permanent Viscous Traction four-wheel drive system ensures that every force is constantly translated into movement. As in the original Murciélago LP640, the Reventón accelerates from 0 to 100 km/h in just 3.4 seconds, with a maximum speed of over 340 km/h.
