The Best Backyard Engineering at Its Best: Dual-Engine Pontiac G6

This guy needs someone to help him with his suspension.

Are you still able to recall the Pontiac G6 model? The midsize model was produced by General Motors from 2004 to 2010. It was built on the Epsilon platform that was shared with models such as the Chevrolet Malibu or the Saab 9-3. Although it wasn’t very special, it was a decent sedan/ coupe that featured cool features such as a remote engine starter system, automatic headlights and a panoramic sunroof. There were four- and six-cylinder engines that produced up to 252 horsepower (188kilowatts). The G6 was equipped with a single engine at its front, as in every other production car.

This is not the case for the car shown in the video. This clip is from David Stapley, YouTube. It shows what appears to be an early G6 blue sedan with the four-cylinder engine at its front. The car was equipped with a 2.4-liter engine, which can produce either 169 horsepower (126 kW), or 164 horsepower (122 kW) depending upon the model year. But! You’ll notice a second engine behind the front seats. It appears to be a V6.

Although it’s shocking to see the engine naked behind your back, with all the wiring exposed, you will be even more shocked when the second motor actually begins. Although the video does not give a complete explanation of the car’s operation, the creator provides some additional information in the comments section.

“The stock programming of the ECUs allows you to be in 2nd in the front trans, and 4th in back. The front motor revs high until it corrects the gears. Because the torque converter absorbs everything, gear changes are very smooth. You can fly forward if you give the engine gas in this situation.

Another video shows that the rear engine is on front-wheel drive suspension with a steering wheel. The video below explains everything so take a look at the video and let the owner know if you have any suggestions for fixing his suspension issues.
