Local Trade, 4.2L Engine, CD Radio, 4x4, Keyless Entry! The hard-working TrailBlazer competes enthusiastically against the Ford Explorer and other midsize rivals in passing power, ride comfort and handling prowess. The TrailBlazer holds a 275-horsepower, 4.2-liter, all-aluminum inline-six-cylinder engine. Performance is a strong point. When tromping on the gas, few drivers are likely to realize that the source of power is an inline-six-cylinder engine rather than a V-8. Not only is engine sound barely discernible, but road noise is also virtually absent. The Autotrac systems Auto 4WD setting transfers power to all four wheels automatically as conditions change. All-disc antilock brakes and seat-mounted side-impact airbags are standard. Dual-stage front airbags deploy with varying force. Interior space is ample in both the front and rear, and passengers occupy seats that are somewhat firm.
