Expected to make its debut for the 2004 model year, the Chevrolet
Colorado will replace the very old S-10 and is part of a joint venture
between Isuzu and GM.
Colorado will move up the size ladder from the S-10 to have roughly
the same dimensions as the 2002
choices are expected to be a four-cylinder and two inline five cylinders
- naturally aspirated or turbocharged. All engine versions will
be based on the same GM Atlas architecture of the 4.2-liter Vortec
4200 inline six that debuted in the TrailBlazer SUV.
By the time it appears in 2004, the Colorado will share much of
its aggressive looks with the rest of the GM truck family - similar
to the 2002 Avalanche.
Look for an interior very similar to the 2002 Trailblazer SUV.
Engine choices for Chevrolet Colorado are expected to include an
inline four cylinder, naturally aspirated inline five cylinder and
turbocharged five cylinder. The I4 will be standard.
I5 will be built at GM's Flint, Michigan plant, on the same lines
as the six and it will also be produced in GM's other new inline
engine plant, in Tonawanda, N.Y., sharing that facility with the
engines share roughly three-quarters of their parts. All are DOHC
with four valves per cylinder, a high compression ratio (10.0:1),
variable valve timing, coil-on-plug ignition, electronically controlled
throttles and fuel injection.
