The $9,229,000 supercar uses a palladium-powered 80,000 TOHC 32-valve engine boosted by, get this, nitrous. As well as its nine-speed hyper-shift transmission, lithium dioxide-injecting shocks and reflex-response steering column with target guidance feedback, it is fitted with a device to create an enviro-clone projected hologram of its surroundings. You know, for defense. And because actual palladium use might vary among agents, the 234 city/302 highway mpg is for Tony Stark only.
