All You Need To Know About V8 Engines

A V8 engine has eight cylinders arranged in a V shape. It delivers strong power and torque, which makes it ideal for luxury and sports cars. Even in 2025, many drivers still choose V8s for their performance, engine sound, and reliability—despite the rise of electric and hybrid vehicles.

When Was The V8 Engine First Used In Cars?

The V8 engine was first designed in the 19th century for ships and planes. Renault used it in cars in 1904, followed by Rolls-Royce in 1905. Rolls-Royce introduced the first street car with a 3.5-litre V8 engine. Since then, the V8 has become a symbol of power and prestige.

How Is A V8 Engine Built?

A V8 engine contains eight cylinders in two banks of four. These banks are set at a 90° angle, forming a “V” shape. When one piston is at the top on one side, the matching piston on the opposite side moves down. This creates balanced primary forces.

To better understand parts like cylinder banks and cooling paths, read this guide to the engine block.

To reduce vibration from secondary forces, manufacturers use friction dampers and engine mounts. The engine runs on a typical four-stroke cycle, like most internal combustion engines.

How Does A V8 Engine Work?

Here’s how a V8 engine works step by step:

1. The air-fuel mixture enters the cylinder through the valvetrain.
2. The piston compresses the mixture.
3. The spark plug ignites it.
4. The explosion moves the piston down to generate power.

To explore more about how cylinder heads and valve systems function, see this engine head guide. 

There are two main valve control methods:

• Overhead camshafts (chain-driven)
• Pushrods with rocker arms

The firing order varies by model, but the most common is 1-8-7-2-6-5-4-3. Many V8s now also have counterbalancers to reduce the movement and vibrations caused by the pistons.

What Are The Differences Between V6, V8, and V12 Engines?

Here’s a comparison table to help understand how V8 engines compare with V6 and V12:

Why Do People Still Prefer V8 Engines in 2025?

Here are the key reasons why many drivers still pick a V8 engine:

• Compact Build: Two banks of cylinders allow a V8 to fit into smaller engine bays.
• Balanced Power: Opposing piston movement helps balance forces for smoother performance.
• Lower Manufacturing Cost: Fewer parts reduce overall production costs.
• Easy Maintenance: Cylinder heads are easy to reach, lowering labour time.
• Better Fuel Flow: The intake manifold gives a balanced air-fuel mix to all cylinders.

Is the V8 Engine Still Relevant in the Future?

Yes, the V8 engine still has a place in 2025—though with changes:

• Hybrid Technology: Some modern V8s are paired with electric motors.
• Smaller Turbocharged Alternatives: Four- and six-cylinder turbo engines are replacing V8s in some models.
• Stricter Emission Rules: Car makers are updating or phasing out some V8s to meet global emissions laws.
• Collector and Performance Cars: V8s are often used in limited-edition or high-end models.

Which Latest Cars Still Use a V8 Engine in the UAE?

Here are some 2024–2025 models that still offer a V8 engine:
