Chevy’s 2.7L I4 engine is one of the largest gasoline four cylinders sold today in a road car. It’s packed with clever technology, like a dual volute turbocharger, advanced three position camshaft, active thermal management, integrated exhaust manifold, and jumbo cylinders. The engine can be found in the Chevy Silverado producing 310 horsepower and 350 lb-ft of torque, and in the Cadillac CT4-V producing 325 horsepower and 380 lb-ft of torque. Check out the video to learn all about the clever camshaft and turbocharger used!

But its true. V8s do get better economy. It takes a 4 cylinder 2x the rpm to get the car to move and to accelerate it takes more time meaning 0-60 takes longer burning more gas. Less torque means more rpm needed to move. V8 have lpts of torque it requires very little rpm to get it to move.

@@baileyhatfield4273what? Camless valve trains are much easier to service and repair, you just change the broken solenoid! And no more catastrophic engine failures because valves aren’t physically able to fall into the combustion chamber anymore. Unfortunately the forced use of electric vehicles by governments worldwide means that this amazing technology was never implemented to the mass market and will never happen again since it’s forbidden from 2030 on to bring cars with a internal combustion engine to the mass market. I won’t mention the catastrophic events this will trigger because it’s just too depressing. Just remember that free valve systems are incredibly reliable and powerful! The only negative is a higher price in the first generations, but that would vanish in a normal production cycle without political intervention..

A 4 cylinder engine in a truck? Apparently yes, it's a thing. But hey, it's got 310 horsepower and tons of torque, amirite? But the sad truth is most people driving pickup trucks aren't hauling anything other than super light stuff. And they don't go off roading (no, dirt roads don't count, and parking on the grass doesn't count either). So most people really should be driving the 4 cylinder Silverado or the 2.7L F150 but won't.

All three engines exhibited ridiculously high oil consumption rates, revealed tremendous amounts of carbon buildup post detonation on deactivating cylinders, and were found to be fit for road use by dealer techs within days of complete failure.
