All the critics appreciate their performance and durability.

But do you know they have a huge difference?

This is the most informative article on the net that will clarify all your doubts with a very simple explanation.

What is Trim Level?

Most people think LS stands for Luxury Sport, LT means Luxury Touring, and LTZ stands for Luxury Touring Z.

Trim levels are the different versions of the same model of a specific vehicle.

So, a vehicle trim means another version of the same model.

Vehicle manufacturers like General Motors produce cars, trucks, and SUVs and include some basic features.

When a specific model of a particular vehicle gets popular, the manufacturer adds extra features like a more attractive interior, upholstery, better transmission, modified engine, modified driving system, better comfort level, etc., on the same model give them different trim name or level.

For example, Chevy LS, LT or LTZ are the same model of Chevy with different trim levels or names.

History of Chevy LS Engine

The small-block Chevy engine originally started as a Generation: I engine in 1955 that was the first V-8 engine.

Gen: II, also known as LT1, came out in 1992 but short many parts with Gen: I.

From 1997 to 2013, all Chevy LS engines are Gen: III and Gen: IV engines.

In 1997, the LS engine debuted. It was a Gen: IV engine.

It’s a good engine. 5.7L LS one engine came out in 1997, putting out 345 Horsepower in the Corvette.

In 1998, Chevrolet used the LS engine in Camaro and Firebird with a slight detune that makes 305 Horsepower.

All of them performed pretty well back those days.

That is why it was pretty easy to find LS engines.

In 1999, Chevrolet dropped V8 LS engines in some of their truck and SUV models and offered it in three engine displacements 4.8 liters, 5.3 liters & 6.0 liters.

6.0 liter is typically found in ¾ and 1-ton trucks.

All three of the engines were using the cathedral port then.

Truck engines are Iron made, and car engines are Aluminum made.

Aluminum engines are about 100 pounds lighter than the Iron made Chevy truck engines.

In 2001, Chevrolet used Gen: IV LS engines in Corvette-ZO6, producing 385 Horsepower.

It had a new intake manifold, better cylinder heads, redesigned combustion chamber, higher compression ratio, thin-walled cast iron exhaust manifold, hotter camshaft.

LS engine began to use Active Fuel Management System (AFM) in 2005 to improve the gas mileage.

In 2006, Chevrolet introduced a 7.0 liter LS engine to produce 505 Horsepower.

They also introduced 6-speed 6L80E transmission in 2006.

In 2007, Chevrolet began to use Aluminum LS engines in their trucks which they used only in cars before.

Aluminum engines are about 100 pounds lighter than Iron engines.

It provides better acceleration, better braking, and better handling.

6.2 liter LS engines were first used in 2007 in Chevy Escalade and Denali.

It’s an Aluminum block engine with high compression, high displacement, and around 400 Horsepower.

In 2008, we saw the debut of LS3 on the Corvette.

It can produce 430 Horsepower. It’s considered the best LS engine.

GM dropped its manual transmission option from trucks in 2008.

In 2009, we saw two debuts, the supercharged LS9 on the zr1 and the LSA in the Cadillac CTS-V.

Corvette has 638 Horsepower, and the Cadillac CTS-V has 556 Horsepower with titanium rods & intake valves.

In 2010, the Camaro was back with 426 HP on the manual trans version and 400 HP on the automatic transversion.

It was an L99 version engine. L9h and the lh9 are different versions of the Chevy engine.

Most people get confused about them.

L9h is a 6.2 liter with 100 more horsepower than the lh9 version.

In 2011, there were no mentionable changes; CTS-V coupe and wagon were added to the list of LS engines.

In 2012, there were not a lot of changes.

In 2013, a new Corvette model, the 427 which was convertible.

It’s was pretty much like the zo6 model. It was added to the Chevy LS engine list.

In 2014, Generation: V, a new type of engine known as LT was introduced on the c7 Corvette.

All the LT, Gen: V engines are Aluminum blocked.

On the car side, the Corvette debuts with 7-speed manual transmission.

On the truck side, there are two options, 5.3l and 6.2l.

The 4.8 liter is no longer available. 5.3 is also considered a reliable LS engine. z28 Camaro in introduced with the LS7 from the Corvette.

In 2015, there was no change on the car side, and it was the last year of z28.

The last of the LS engines are still carried on heavy-duty pickup trucks and vans on the truck side.

But SUVs like Tahoe got Gen: V LS engines this year.

In 2016, LS3, L99, LS7 (Gen: V) were all out of production.

There were no LS engines left on the car side.

There were a few LS engines left on the truck side, mostly in Vans.

2017 was the last year of Chevy LS engines.

After the production of 21 years, GM decided not to manufacture more LS engines till now.

History of Chevy LT Engine

Chevy LT1, Gen: II was produced from 1992 to 1996.

LT1 could produce 200 to 330 Horsepower.

After 1996 GM stopped producing the Chevy LT1.

After 18 years, GM began to manufacture LT in 2014 again.

I don’t think Chevy LT is a minor upgrade of LS. Instead, it’s entirely a different engine with more Horsepower and Fuel efficiency.

About 98% of the engine material is entirely new; only 5 parts from LS are carried out.

The LT has the most amazing Horsepower and Torque curve.

It can easily produce 355 to 495 Horsepower at low RPM than LT engines.

All of the Chevy LT engines from 2014 till now are Generation: V engines with only an Aluminum block version.

Both in truck and cars Aluminum version of the LT engine is being used till now.

In 2014, Chevy LT was introduced on c7 Corvette.

Corvette debuts with 7-speed transmission.

On the truck, there were 5.3l and 6.2l versions.

From 2014 till now, GM is producing LT and LTZ trims of the engine.

Chevy LS vs LT: Which is a Better Choice?

Both of them are reliable and performance-oriented.

But Chevy LT is far better than LS. Let’s find out why LT is far better than LS-

01. Dynamic Fuel Management (DFM)

As we mentioned before, AFM was introduced in 2005 in LS engines.

Many users reported that it caused many issues with the engine.

AFM shuts off half of the cylinder to save fuel consumption.

In 2019, GM developed the AFM and introduced Dynamic Fuel Management or DFM system in Silverado, a smarter version of AFM.

DFM is being used in Chevy LT and LTZ engines to save fuel within the engine’s efficiency.

DFM functions far better than AFM.

02. Direct Injection

LT has a Direct Injection system which LS lacks.

Direct Injection sprays fuel directly into the cylinder.

It controls the fuel injection spray pattern.

It ensures the complete burn of the fuel of the cylinders.

It helps to create more Horsepower and saves fuel.

03. PSI

One of the most amazing things about Direct Injection is the pressure that the system uses.

The old carbureted engine uses 5 to 10 PSI as a balloon has.

Chevy LS engine versions use 30 to 70 PSI which is equivalent to a bicycle’s tire pressure.

But the Chevy LT engine version uses 2900 PSI which is far greater than the LS engines. 2900 PSI is like a high-powered pressure washer.

04. Cylinder Head Casting

LT has all-new cylinder head casting, a completely different casting from LS.

The intake valves are reversed in the LT engines.

05. Variable Valve Timing (VVT)

LT has Variable Valve Timing (VVT-2.0). LS also has VVT, but there is a big difference.

LT has continuous VVT, but the LS engine’s VVT was not continuous.

They turn on or off sometimes.

Continuous Valve Timing allows the LT version to produce more torque which LS lacks.

VVT gives better engine performance better mileage with lower emission.

06. Gas Mileage & Performance

Chevy LT has Dynic Fuel Management or DFM, an upgrade version of AFM.

So, the LT engine provides better fuel economy and less emission than LS versions.

07. Engine Weight

There are 2 versions of engines, Aluminum & Iron.

All of the Chevy LT engines are made of Aluminum.

LS engines are made of both Iron and Aluminum versions.

So, LT is always a better choice cause the Aluminum engine provides better breaking, controlling and performance than the LS versions.

08. Engine Weight

As we mentioned before, LT has only Aluminum versions.

On the other hand, LS has both Iron and Aluminum versions.

We all know, Aluminum is much lighter than Iron.

So, LT engines are about 50 pounds lighter than the Iron versions.

09. Gen: I to Gen: V

GM first manufactured the Carburetor engine in 1955. It was Gen: I engines.

From 1997 to 2013, GM produced Gen: III and Gen: IV engines LS engines.

From 2014 till now, GM is manufacturing Gen: V Chevy LT engine versions.

GM has upgraded the engines with Generation to Generation.

So, Gen: V Chevy has better features and amenities than LS versions.

10. Horsepower & Torque

Gen: I, Chevy engine could produce 110-370 Horsepower. Gen: II, Chevy LS1 could produce 200-330 Horsepower.

Gen: III & IV, Chevy LS can produce 255 to 505 Horsepower.

And Gen: V, Chevy LT can produce 355-495 Horsepower.

The Chevy LT version is the clear winner in terms of Horsepower.

Chevy LT can produce much more torque than the LS engines as mentioned before.

You will find the basic differences between Chevy LS vs LT in this video-

11. Driving Option

Chevy LS and LT have two driving options, 2WD & 4WD.

You can choose whatever you want.

But LT 4WD has more Horsepower of Torque than the LS 4WD.

12. Which is the Cheapest?

At first Gen: II, LS was introduced by General Motors in 1997, where LT is another trim or update version of LS introduced in 2014.

So, Chevy LS is considered as the base model.

LT is the upgraded version of the same model with some extra features.

So, naturally, LS is cheaper than LT since it has fewer features than LT.

Chevy LS is the base model; it’s less expensive than the LT versions.

LT has many modern technologies features that LS lacks.

So, LS is the cheapest, and LT is the most expensive in terms of money.

13. Chevy LS vs LT: Which One is a Better Option for You?

We think you already know which is the better option.

In terms of technology, premium features, performance and amenities LT engine is far better.

If you want to differentiate between Chevy LS vs LT.

Clearly, LT will be a better choice than LS.


We think now you know the Main differences between Chevy LS vs LT.

If you are willing to buy one, go for the LT.

If you have a tight budget, then go for LS. Both of them are reliable engines.

You can also buy a second-hand LT if you don’t want to miss the upgraded features.
