Comic book superheroes have been and will continue to hit our screens riding dirty in Acura cars, following the Japanese luxury brand's multi-picture deal with Marvel. Captain American and Thor have already featured them and the next superhero spectacular The Avengers will have a couple of models filling the screen. Recently spotted driving on set was Iron Man/Tony Stark (Robert Downey Jr.), caught in a Acura NSX Spyder concept.

While the Strategic Homeland Intervention, Enforcement, and Logistics Division aka S.H.I.E.L.D. will have this MDX at their disposal. According to the accurate-looking Monroney sticker, the S.H.I.E.L.D. MDX with the Sentinel Package comes with the same Palladium-powered titanium engine, 9-speed hyper-shift and diamond quartz brakes as Stark's roadster, and boasts 234/304 mpg city/highway. An aerial drone is stored away in a briefcase in the back, the steering wheel has a palm-scan ID, and it also comes with a cloaking device - an invisio-shield exo-system wave modifier to be exact.

Other cool features include a bulletproof body, retracting repulsor canon, and advanced targeting system. Running the car won't come cheap as Palladium fuel costs $448/oz. But that won't be a concern to most as the MDX with special tactical packages is priced at almost $6m.
