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!

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..

Gen 2 @ 69k miles. Gen 3 at 4,462 miles.

The Cadillac V16 engines in the 1930's (there were 2 entirely different ones) were developed with the design criteria for "truck" or "coach". They were used for very large, heavy cars.

Years ago Government Motors marketed the 4.3 ltr (essentially a 350 with 2 cylinders lopped off) Turbo as a truck engine, then promptly installed it in a Monte Carlo. It only lasted a couple years-as did my cousin's 4.3 Turbo Monte Carlo engine...

The funny thing is if you look at smaller trucks and SUVs often the V8 options gets as good or sometimes better fuel economy compared to the V6 and 4 cylinder options (excluding small diesels). Power to weight ratio.

@chrisbaker2903 2 жыл бұрын

Yep. The higher the percentage of the engine's power you use most of the time the less economical they seem to get.

Less highway mpg out of their “truck” 4 cylinder than their V8. Go home GM, you’re drunk.

I feel like engineers are over-engineering just because they can.. Why improve an existing platform when you can make something less reliable, less efficient, less powerful, AND more expensive?

@samgford 4 жыл бұрын

@@jrowland6717 is it more expensive? This will likely be the base engine replacing the current v6 at some point. The v8 is a higher price option. I'm not saying that it actually does cost less but just that it wouldn't make sense from a bean counting perspective for gm to do this if it wasn't actually cheaper to produce. Maybe I'm wrong though.

Perhaps this engine is designed for export to many markets where a special tax is assessed on engine's displacement, so the car maker must use a small but boosted engine to avert additional tax.

@warriorpluto : MPG translates directly to emissions, perfect combustion dictates that CO2 production is linear with gas consumption. - it gets worse when NOx gets factored in.

@JDelta87 4 жыл бұрын

warriorpluto It’s still not helping overall with emissions if it takes more fuel to run over the life of the engine. It’s just inefficient in another way.
