Bigger than the regular-length TrailBlazer but just as
capable - if not more so - the TrailBlazer EXT benefits
from all the improvements of its smaller sibling, all the
while offering the added flexibility of an extended wheelbase.
There are new options this year that up the refinement
level, and more standard safety features as well. Yet underneath
it all is the strong foundation that makes the TrailBlazer
so versatile. Both TrailBlazers use hydroformed steel frame
side rails, which form a strong foundation for the trucks'
overall strength and solid feel, even on unpaved surfaces.
The 2005 Chevy TrailBlazer EXT is offered in two trims:
LS and LT. The TrailBlazer is covered separately.
The real upgrade that the Chevy TrailBlazer EXT provides
is in interior room. With its spacious third-row seat, TrailBlazer
EXT can carry up to seven passengers, along with more than
23 cubic feet of stowage space behind the third seat. The
second and third rows can be folded flat, opening up 107
cubic feet of cargo volume.
XM Satellite Radio continues as an option for 2005. It
is joined by some new add-ons, including an upgraded radio/navigation
system with control touch screen in the audio faceplate
and a DVD player.
Additional options on the 2005 Chevy TrailBlazer EXT include
adjustable brake and accelerator pedals, sun visors with
lighted vanity mirrors, an inside rearview mirror with temperature
gauge and compass, rain-sensing wipers and leather seating
surfaces with eight-way-power driver and passenger seats.
Also optional for 2005 are a sunroof and both factory- and
dealer-installed running boards.
There are two available engines this year. The standard
engine is a 4.2-liter inline 6-cylinder model that can generate
275 horsepower at 6000 rpm and 275 lb-ft of torque at 3600
The optional engine is a 5.3-liter V8 that produces 290
horsepower at 5200 rpm and 330 lb-ft of torque at 4000 rpm.
Both engines are mated to a rugged Hydra-Matic 4L60-E electronically
controlled 4-speed automatic transmission.
The V8 uses GM's innovative Displacement on Demand (DOD)
technology. It enables fuel economy gains of up to 8 percent
by reducing the number of cylinders engaged in the combustion
Safety and Security
Upgraded occupant safety is one of the key improvements
to the 2005 Chevy TrailBlazer family. Some of the key upgrades
include an available head side curtain airbag system with
a rollover protection sensing system, an occupant sensing
system for the front passenger, a revised front safety belt
reminder system and the LATCH child seat anchorage system.
