The automotive industry has moved toward smaller engines with turbocharging and supercharging, but there’s no replacement for the sound and power of a V8 engine. While V8s are much less common than they once were, many automakers still offer them in performance cars as well as full-size trucks and SUVs because of their strong horsepower and torque.
Let’s take a closer look at V8 engines, how they work, and the types of vehicles that commonly offer them.
What Does the “V” Stand For?
The “V” in V8 represents the orientation of the cylinder banks. These engines have two banks of four cylinders each, arranged in a “V” shape. This configuration is common among engines with six, eight, 10, or 12 cylinders.
How Does a V8 Work?
Modern V8s are four-stroke internal combustion engines. Air enters the cylinders through the intake valves, fuel is added, and the pistons compress the air-fuel mixture. Spark plugs ignite the mixture, forcing the pistons downward. The pistons then push exhaust gases out through the exhaust valves, and the cycle repeats. It’s worth noting that this is a simplified explanation of a process involving other components and precisely timed events.
The pistons connect through connecting rods to the crankshaft, which transmits power to the transmission and ultimately to the drive wheels.
You may have heard the phrase “there’s no replacement for displacement,” which means that, in general, greater displacement can help an engine produce more power and torque. That said, forced induction, which includes turbocharging and supercharging, can increase the output of a smaller V8, making it more powerful than some larger naturally aspirated engines.

Pros & Cons of a V8
Weighing the power against the trade-offs
Power
The biggest advantage of a V8 is its potential for high horsepower and torque. V8s are found in sports cars for strong performance and trucks for serious towing and hauling.
Simplicity
Naturally aspirated V8s can produce substantial power without the added hardware of a turbocharger or supercharger.
Sound
There’s nothing quite like the satisfying growl of a V8 engine.
Inefficient
V8 engines are generally thirsty for fuel compared to smaller 6- and 4-cylinder engines.
Heavy
Front-engine, V8-powered sports cars can be nose-heavy, which can hurt how the vehicle handles.
Expensive
When a car or truck offers a V8, it’s usually one of the pricier engine options.
What Cars Have a V8?
There are far fewer V8-powered vehicles on sale today than there were a couple of decades ago, but they are still relatively common in high-performance cars, full-size trucks, and full-size SUVs. Vehicles like the Ford Mustang, Chevrolet Silverado 1500, and Cadillac Escalade offer one or more V8 engine options.
Until recently, Dodge’s vehicle lineup offered multiple V8 engines, the brand shifted toward electrification and high-performance 6-cylinder engines as Stellantis reworked its powertrain strategy. Stellantis has since reversed course on some of those decisions, returning the Hemi V8 to the Ram 1500 and confirming plans for the Hemi V8 to play a bigger role in its future internal-combustion lineup.
Finally, full-size trucks and SUVs have traditionally relied on V8s for towing and hauling, although turbocharged V6 and inline-6-cylinder engines have become significantly more capable in recent years.

V8 vs. V6 vs. Inline-6
How cylinder layout shapes power, smoothness, and packaging
Cylinders line up in a single row (inline) or split into two angled banks (V-type). More cylinders generally mean more power, but layout also drives smoothness, size, and cost.
Two banks of four cylinders in a V, on one crankshaft.
Two banks of three cylinders in a V, on one crankshaft.
All six cylinders in a single straight row, on one crankshaft.
Extra cylinders and displacement add up to strong horsepower and torque.
A practical step up from 4-cylinders, without V8-level bulk.
Matches or tops a V6 cylinder-for-cylinder, with linear delivery.
Thirstiest of the three; more moving parts can add to upkeep.
Better mileage than a V8, in a compact, angled footprint.
Naturally balanced, but the block runs roughly twice as long as a V6’s.
Deep, aggressive sound; extra front weight can affect handling.
Quieter and smoother than 4-cylinders for the output it gives.
Refined and low-vibration, thanks to inherent mechanical balance.
Muscle cars, performance coupes, heavy-duty trucks.
Everyday sedans, crossovers, and SUVs on any drivetrain.
Performance sedans and trucks with room for a longer engine bay.
