Are Trailblazers V6 or V8?
The answer depends on the model year and trim. Early Chevrolet TrailBlazers offered V8 options in some trims and used an inline-6 in most configurations; the modern TrailBlazer (2020–present) does not use a V6 or V8, instead relying on turbocharged inline-3 engines.
Historical engine options by generation
The following overview captures the engine configurations that powered TrailBlazer models in their first generations, including the high-performance variant.
- 4.2L inline-6 (standard in many GMT360 TrailBlazers)
- 5.3L V8 (optional on some trims)
- 6.0L V8 (TrailBlazer SS, produced around 2006–2007)
In summary, early TrailBlazers featured inline-6 and V8 options, with the notable exception that the 4.2L engine is an inline configuration rather than a V6. The high-performance SS model is the standout V8 variant from this era.
Current TrailBlazer engine lineup
The modern TrailBlazer lineup, introduced for the 2020 refresh and continuing today, uses small turbocharged engines instead of V6 or V8 powerplants.
- 1.2L turbocharged inline-3 with a CVT
- 1.3L turbocharged inline-3 with a 9-speed automatic
No V6 or V8 engines are offered in the current TrailBlazer lineup; the emphasis is on compact, efficient turbocharged three-cylinder powertrains.
Performance variants and clarifications
The TrailBlazer SS was a mid-2000s special edition that used a 6.0L V8, making it the primary V8-equipped TrailBlazer. In contrast, the modern TrailBlazer focuses on small turbo inline-3s, and there has not been a contemporary V6 or V8 option in this generation.
Summary
Across its history, the TrailBlazer name has spanned multiple engine configurations. Earlier models offered V8 (and a standard inline-6) options, including the performance-oriented SS variant with a 6.0L V8. The current TrailBlazer (2020–present) has moved away from V6/V8 power, instead using turbocharged inline-3 engines for efficiency and modern emissions targets.
