Don't let the nameplates fool you.
Chevy sells a Colorado pickup here in America, and recently introduced the first all-new Trailblazer in nearly two decades. It also sells vehicles under both nameplates in other parts of the world. But the Colorado and Trailblazer we get here share little in common with the ones you'd find overseas.
Just look at the new Storm editions that Holden (Chevy's Aussie sister brand) has rolled out Down Under. Both feature auxiliary LED light bars, black exterior add-ons, and special badges, bundling several thousand dollars' worth of added equipment for only a couple thousand more than the LTZ grade on which they're based. But we're more interested in what lies beneath.
While both the US-market Colorado and the overseas model are both what we'd call mid-size pickups and both wear the same nameplate, the Colorado sold overseas is actually closer to the Isuzu D-Max than the model you'd find at your local Chevy dealer Stateside. Where the foreign-market version can be had in standard or double-cab configurations, ours comes with an extended or crew cab. It's also bigger in every dimension – beefier to satisfy the US market that's more accustomed to full-size pickups (like the Silverado). As different as the two Colorados may be, though, the differences between the two Trailblazers are even more pronounced.
The overseas version of the Trailblazer you see here is an old-school body-on-frame SUV with seven seats, where the new Trailblazer just revealed for the North American market is a compact unibody crossover, slotting in between the Trax and Equinox. And where the two Colorados share some engines in common, the two Trailblazers employ very different powertrains reflecting their vastly different sizes: big diesels and V6s overseas, and tiny 1.2- or 1.3-liter turbos in the US.
Short of driving both versions of each back to back, we're not about to postulate on which are the better pair. But they go to show that, viewed globally, nameplates can be as versatile as they are deceiving.
