2017 Chevrolet Colorado
Chevrolet has update the
2017 Colorado as class-exclusive powertrain combination that's meant to
"reignite" the midsize truck segment, according to the automaker.
After previously introducing new
features such as a diesel engine and advanced technologies like Apple CarPlay
and Android Auto on the Colorado, now comes an all-new V6 engine and an
eight-speed automatic transmission.
Having reached its second generation,
Chevrolet's double-overhead-cam engine architecture retains the same 3.6-liter
displacement as before, but adds improved valve timing for intake and exhaust,
improved direct injection and for the first time, Active Fuel Management
(cylinder deactivation), disabling two cylinders under light throttle
applications. Horsepower and torque have also increased to 308 HP at
6,800 rpm and 373 Nm at 4,000 rpm.
Working together with the engine is a
class-exclusive GM-developed Hydra-Matic 8L45 eight-speed automatic, which
remains roughly the same size and weight as the 6L80 six-speed automatic it
replaces. However, the new gearbox has a wider 7.0 overall gear ratio spread
over the out-going's 6.0 ratio, helping drivers move forward more confidently
with a heavy load, while the lower rear axle ratios reduce engine rpm on the
highway for improved efficiency.
The 2017 Colorado with its new model
year upgrades is set to hit dealerships in the fourth quarter of this year.
