Do I Need a V8? Or Is a V6 Good Enough?

The automotive industry has evolved over the years as emissions, fuel economy, and safety regulations have changed. While there are still quite a few larger engines available today, many automakers now rely on smaller four- and six-cylinder engines with turbochargers that can deliver power levels similar to hefty V8 engines while typically producing fewer emissions and returning better fuel economy.

If you’re shopping for a V6- or V8-powered vehicle, we’ve got you covered. This overview explains the major differences between the two engine types, and we’ll dive into some of the reasons one might be a better choice for you than the other. Let’s get rolling.

V6 vs. V8: The Highlights

The only difference between V6 and V8 engines is the number of cylinders, right? Think again.

When a V6 Engine is the Right Choice

While many people probably prefer a big V8 when it’s available, choosing a six-cylinder engine doesn’t mean giving up on performance, power, or capability.

Six-cylinder engines, including inline-six options, often offer a better balance of power and fuel efficiency than V8 engines do, making them well suited for drivers who occasionally tow but want mproved fuel economy on everyday trips.
V6 and inline-six-cylinder engines are usually smoother and more subdued than their eight-cylinder counterparts, giving many vehicles a more relaxed, refined feeling on the road.
Six-cylinder engines are typically lighter than V8s, which improves handling and driving dynamics for many vehicles.
In most cases, six-cylinder engines are less expensive to produce and buy than V8s.

Some automakers produce inline-six-cylinder engines, which place all six cylinders in a row instead of the three-by-three setup seen in most V6 engines. The design gives engines better balance, making them smoother in operation. That said, V6 engines are shorter, making them better for vehicles with limited under-hood space.

When a V8 Engine is the Right Choice

Gas-powered V8 engines remain workhorses of the automotive world, but they’re far more advanced than the gas-guzzling engines from years past.

V8 engines are great for people who tow frequently. They often provide better torque and horsepower and are well suited for heavier loads, though some modern turbocharged six-cylinder engines can match or exceed their output.
V8 engines remain a better choice for full-size trucks and SUVs, especially for drivers who prioritize maximum towing capacity, performance, or long-term heavy use.
People who want a beefy sound should opt for a V8.
