S2000 mule : This rather odd-looking S2000 is, we believe, a development 'mule' for the new NSX supercar: a modified body, longer and wider than that of the production S2000, to test the all-new supercar's powertrain and running gear. Check out the extended cabin on this prototype, and the bulging bonnet: there's a large engine under there, which could well be the front-mounted V10 as promised by Honda.
