PONTIAC G8 |
In terms of horsepower, the Pontiac G8 offers plenty of bang for your buck. Both the V6 and V8 models offer power under the hood without the exorbitant cost that usually accompanies it. You'll have your choice between two engines. The V6 comes with a 261-horsepower 3.6-liter engine while the V8 offers a stunning 362-horsepower 6.0-liter monster. So, let's take a moment to explore both.
The Pontiac G8 V6 Engine
The G8's LY7 V6 engine is a 3.6-liter workhorse. When it hits 261-horsepower, the engine reaches approximately 6,300 rpm. It can hit 250 ft. lbs. while maintaining an easy 3,200 rpm. One of the notable improvements of this engine is that it includes a variable intake system (something that was missing in the LYZ). The entire system is managed and regulated by the G8's ECM. The valve enclosed within the intake manifold adjusts based upon the load and speed demanded from the engine. It's designed to provide more torque than a standard 3.6-liter engine while simultaneously hitting higher horsepower.
The block and heads of the LY7 are aluminum cast and include cast-in iron liners that are systematically cooled by squirters that shoot oil at the piston's underside. This is smart engineering to deliver a high-performance engine in a V6 shell.
The Pontiac G8 V8 Engine
The G8's L76 V8 engine has been getting a lot of attention. It hits 362-horsepower at 5,700 rpm and includes a 6.0-liter unit. It will hit 391 ft. lbs. while easing into 4,400 rpm. In case you missed the numbers, that's a healthy 12 more horsepower than the acclaimed Hemi (excluding the SRT Hemi) that you'll find in the Charger. The G8's torque is actually comparable to the torque offered by the Charger's Hemi. That's impressive.
When you buy a standard G8, it comes with a six-speed automatic transmission (we'll talk about the transmission in more detail in a moment). From a dead stop, the G8 GT model should hit 60 mph in under 6 second ... | | | |
