Well, not all of Autoweek. Just, like, one guy. The Rolls-Royce 100EX prototype, on which Autoblog provided the initial inside scoop eons ago, is a very substantial-looking roadster with a 9.0 liter V16 engine. That's right people, I said V16, and it's packing, at the barest minimum, 600 horses. Autoweek had the hard luck of being shuttled around the famous Goodwood Circuit in the 100EX, with RR design man Ian Cameron at the controls. Their up-close look at the $4 million one-off reveals a Phantom-esque design, although slightly smaller and lighter overall. Fake teak paneling is so well-executed that it is difficult to apprehend as fake. The windshield-holding unit is milled from a single piece of aluminum. All in all, to ride in the 100EX prototype is to be within a brilliantly machined instrument. When and if the 100EX comes to fruition, the V16 unfortunately won't be a part of it. The standard V12 from the Phantom will have to suffice.
