The latest information on the Lamborghini supercar is that it derives its inspiration from the Lockheed F-22 Raptor, the most sophisticated attack aircraft in America's aerial Air Force arsenal. As homage to the muse, the cars will be painted gray and fitted with stylized instrument panels. According to Piston Heads, the boys from Sant' Agata (though they mention Modena) have admitted to be building such a car, but now only ten are coming to the US, not the 15 previously reported.

There were claims that the car would be shown to a tiny number of folks at this year's Pebble Beach concourse. We were there and we can assure you that we didn't see, read, or hear about a Raptor-inspired $1.5 million Lamborghini anywhere near Monterey. And we can't imagine how such a secret could have been kept on a peninsula teeming with multi-millionaire car crazy collectors. We'll all have to hold our breath until Frankfurt, and we cannot wait to see what this thing is and whether it's worth more than four times the cost of an LP640.
