There were tradeoffs to carefully consider during the transition from screen to reality.
Wickham originally wanted the XST to have a stretched wheelbase to accommodate a longer bed and provide more stylistic control over the C-pillar's shape. The extra inches, however, would prove to be impractical because of the amount of work required to stay within the bounds of the Axiom SUV's body taper, noticed as you move from front to rear over the top of the truck.
The triangular racks seen mounted just behind the rear doors on the bed rails in the original sketches were also ditched. In reality they would have gotten in the way of the XST's "switchgate" cabin access system which functions similarly to the Chevrolet Avalanche's Midgate. Their resemblance to the Avalanche's own sails didn't help either.
Interior design responsibility also came under Wickham's direction. The Axiom's all natural leather and cloth interior surfaces were replaced with synthetics like vinyl and neoprene. But again, like the exterior, the interior's design is very closely aligned with what's in production today to make the XST as feasible as possible.
When asked about his favorite part of the XST's design, Wickham is quick to point out the very trick tailgate mounted bed extender that folds flush with the bed when not in use. It's hinged in a unique way that makes first time witnesses think it's an optical illusion - origami meets aluminum.
There are many concepts that are all show and no go. They might be nicely painted exteriors skinned over a clay model or only drivable at 20mph or less. The Axiom XST is a runner, able to cruise around like any other Axiom on the highway but you probably wouldn't want to throw a heavy load in the back.
The average budget for a concept car shown in Detroit is in the neighborhood of $1M dollars. Sticking closely to production DNA, Isuzu was able to keep the XST's budget to well under that figure.
not the XST winds up in your driveway will be determined by public and
press reaction to the concept, which seems to be positive so far. So,
while the XST is only halfway there, Brent Wickham and his design team
at Isuzu and IDC can take a well deserved break knowing they have already
