Of course, the Halo Pet Safety System still relies on the owner giving enough of a damn to go back out to the car and turn on the air. That's a pretty big Achilles' Heel when you consider that most responsible pet owners shouldn't need to spend the $100 that this gadget costs in the first place. [Product Page via Gizmag]

Unlike the pictures we saw earlier, the doors and the rear hatch roof were now removed on the vehicle I checked out, which made the HX look even more familiar and justified my relentless drilling of the designers about Halo.

I fully expected Rojas and Jablonski to quickly deny any kind of link—but the llevel of denial was stunning. Not only did Rojas quickly shoot down even the slightest bit of speculation, he was adamant, repeatedly stating the he neither owns an Xbox nor plays Halo. Jablonski echoed these denials. On a normal day that would be a fine, except a few days prior GM's director of exterior design for the HX, Carl Zipfel, admitted that "We all play [Halo]."

If you want to take a gander at this thing, it's clearly not a direct copy of the Warthog, but there are certain factors that one could draw assumptions from. The removable wheel fenders expose plenty of wheel-well action, which looks a lot like the Warthog. A completely covered and protected undercarriage and wheel wells is a necessity in Halo, to protect virtual combatants from imaginary barrages of assorted munitions. The Hummer designers must be anticipating that the HX will encounter similar action in the real world because the vehicle's protected undercarriage is a highly touted feature. The tailgate also opens for quick loading into the back with the folded down seats for when you have to quickly jump in and mount a gun turret. The roof of the HX is also removable, revealing a square top, which could be construed as similar to the Warthog's t-top.

So what's the final word? There isn't one. We've heard mentions of a link from insiders. We've heard speculation of a link across the Web. And even Rojas and Jablonski were quick to joke about the possibility of some kind of partnership with Bungie, makers of Halo, to get the Hummer HX into the game. While in-game advertising isn't something new, Bungie is not the kind of studio to participate in that, but on the other hand, Bungie's partial equity owner, Microsoft, would be more likely to join in.

It is safe to say that the Hummer HX is not a direct copy of the Warthog from Halo, but I can't get away from the fact that they share similar functionality, purposes, intentions—and that the designers were so adamant about their denials. Regardless, the fact of the matter is that neither the Warthog from Halo or the Hummer HX are actual production models. It's intriguing to see video games having a little bit of influence in the automotive industry, even if it is just with a conceptual design that will never see the light of day. Will we ever see GM hire away designers from the video game industry? Who knows?

5.) Saab 9-4x BioPower: Stainless-steel ski rack. Sure, it looks fine, and having the titanium-carbon-fiber Rossignols on the roof is just too risky these days. But where will the douchebag couple who spends the eight hours to Vermont talking about their trip to St. Bart's sit? Think about it.

4.) Saturn Flextreme: Clamshell trunk. While shellfish and trunk space are both well liked, combining the two is a pipe dream that'll, unfortunately, never be fulfilled. Saturn designers deserve credit for out-of-the-mollusk thinking, though. Hiho!

3.) Lincoln MKT: Those massive gauge tubes were reportedly inspired by Swarovski crystal. While they do add an upmarket, Ice Pirates ambiance to the Lincoln, no corporate lawyer in Scarsdale who's ever had a knock-down-drag-out with his spouse in the living room would risk another crystal decanter to the face, under any circumstances.

2.) Maybach Landaulet: Rear-seat convertible top. When everything shakes out, the 2010s may be known as the decade robber barons returned to lord it over the faltering middle class. But will the new JP Morgans and Vanderbilts really want to be chauffeured al fresco? We're betting not. These days, the proles have guns and laser scopes.

1.) Mazda Furai: Itself.

BONUS: One Feature Missing from a Detroit Concept Car: Hummer HX. Notwithstanding its visual connection to the Halo 3 Warthog fighting vehicle, the Hummer HX concept could be a great success on the dystopian streets of post-revolutionary America. But the kids would demand a turret mount, a glaring omission from the concept. Keeping the Covenant from attacking humanoid refugee shelters would be impossible without it.

"This will validate the engineering proficiency of Hyundai...it's a sure sign we've arrived."

Yes, a sure sign of arrival and engineering proficiency will no longer be a Dodge Viper, Saturn Sky Redline or Chevy Corvette in the driveway — it'll be a car based on the Hyundai Sonata or Azera. Sure.
