Chevy is currently in the process of launching the all-new Chevy TrailBlazer in South Africa. As expected, the midsize SUV will cradle the familiar pair of 2.5 and 2.8 liter four-cylinder turbo-diesel Duramax engines, but it will also offer a six-cylinder 3.6 liter gasoline engine.
According to Chevrolet, the 3.6 liter produces a maximum of 176 kW (236 hp) and a peak torque of 329 Nm (242 lb.-ft.). Of the vehicle’s engine range (including the two Duramax diesel units), the V6 makes the most horsepower but the least amount of torque. The six-banger features sequential fuel injection and is exclusively mated to an electronically-controlled 6-speed automatic transmission with DSC (Driver Shift Control) putting down power through all four wheels.
The all-new TrailBlazer rides on an all-new vehicle architecture known as GMT355 shared with the Chevy Colorado midsize pickup truck.
|2.5L DURAMAX DIESEL||2.8L DURAMAX DIESEL||3.6L PETROL|
|TORQUE Nm||350||470 (AUTO)/440 (MANUAL)||329|
|TORQUE LB.-FT.||258||346 (AUTO)/324 (MANUAL)||242|
The GM Authority Take
The engine doesn’t seem to be any of the recent direct-injected V6 engines such as GM’s LLT or LFX units. Instead, it appears to be the LY7 unit that was last seen in the last-generation Chevy Malibu.
GM Authority reached out to GM South Africa for clarification, but did not receive a reply in time for publication. We will update this article if we hear back.
Postscript: we have confirmed with GM’s Media team in South Africa that the engine is, in fact, the LY7.
Since the 3.6 liter V6 in the TrailBlazer is indeed the old-school LY7, we wonder why GM chose to use the powerplant instead of the much more powerful and modern LFX unit. Even so, GM’s choice not to use the LFX in the all-new TrailBlazer in South Africa does not necessarily indicate that other TrailBlazer markets won’t see the automaker’s most modern V6 mill (LFX).
