I review the Chevy/GMC 1500 2.7L Inline 4 cylinder TURBO L3B engine as a Heavy Duty Mechanic. This 4 cylinder turbo charged engine produced 310 hp and 430lb-ft of torque. I test out this engines towing performance and review the engines acceleration, fuel economy (mpg), engine braking and general towing experience.

So I was actually very surprised by this 2.7L turbo charged inline 4 towing experience. this engines is actually very capable when it comes to towing. This engine is not the fastest in comparison to other engines in the 1500 truck segmant but this engines shines when it comes to torque delivery.

rarely did this 2.7L turbo charged engine go over 2500 RPM with this 8000lb load which is remarkable. I thought foresure this engine would be revving very high but the high torque figures kept those wheel turning under load

the main reason why this engines can create such good torque comes from the massive stroke which naturally allows engines to build torque from the naturally large crank throw.

another reason why this engine was so unexpectagly good at towing has to do with the turbo. turbo's are great when towing because they can simply supply more engine power on demand without having to downshift the transmissions and get into higher RPM's

overall this 2.7L turbo charged 4 cylinder engine was impressive for such a small package. I felt very comfortable towing 8,000lbs.

the one issues or downside of this engine was fuel economy, fuel economy was actually pretty high at around 11.7mpg for only a 4 cylinder engine. if you are expecting great fuel economy go buy a diesel because this engine when towing will drink lots of fuel.

hope you guys liked the video!
