Cadillac’s Giant 4-Cylinder Engine Has A New Dual Volute Turbo

How Dual Volute Turbos Work In Chevy's Massive Four-Cylinder Engine

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!

"I don't know the rules anymore"

None of us do, brother.

In this episode of Engineering Explained:
A CT4-V is a truck;
An SUV is a Coupe;
And for better mileage on the highway, get the V8

"I don't know the rules anymore"

That cut. That one right there. I felt you, brother.

[StuFletch]

Moral of the story just get two of those turbos and put them on the V8

[JimmyNines]

What I heard was “GM was able to produce a part-time 2 cylinder engine that is able to consume more fuel than a V8, it’s completely pointless. But it’s got a cool turbo!”
Did I get that right?

[gregmorris]

I’m going to refer to motorcycles as windowless panel vans.

[luizsudbrack]

Cool turbo. The engine itself looks like a solution in search of a problem.

GM: we made a 4 cylinder that rivals the dodge viper's 8.4l V10 for fuel economy.

Engineer “ Look at how complicated we can make an engine”; Marketing “What a great marketing tool”; Parts and Service “We’re in the money now!”

[drivingwithtaz]

Dude I nearly choked when you said if you want better efficiency get the V8 lmaooo

[SavageBunny]

I love that rear mounted oil pump, just perfect for the "not known to fail" GM oil pumps....

[violentshemp]

engineers: we see 0 valvetrain issues with this design.
average consumer: hold my lobe shavings

[JustinBone]

Jason that rant in the beginning had me in tears, I feel the same reading so many things in the auto news world these days. lol

[FubukiShiromiya]

That V8 highway economy reaction was perfect.

“I don’t know the rules anymore...” 🤣 Welcome to 2020 -lol

When you're towing uphill in your 4 banger Silverado and VTEC kicks in👌👌👌

[alexmonje]

A Cadillac sedan is a truck, a Mercedes genuine SUV is a coupe and if you want the best fuel economy on the highway get the V8.

"We have just lost cabin pressure"

this has got to be the funniest engineering explained video iv'e seen in a long time

This engine was voted most likely to spend all its time in the dealer's service shop.
