4-Cylinder Turbo vs. V6 Engine

Over the course of several years, more and more automakers, including GMC and Buick, have been replacing V6 engines with turbocharged 4-cylinder engines in their new vehicles. Why is that? The bottom line is that turbocharged engines are more fuel-efficient versus V6 models on Orchard Park roads and beyond. So when shopping for a new or used vehicle with a 4-cylinder turbo vs. a V6 engine, keep a few things in mind if you’re curious. 

Read our guide as we compare the 4-cylinder turbo vs. a V6 engine at Robert Basil Buick GMC near Buffalo. We think it will shed some light as to what engine is better for your drives in Blasdell and West Seneca.

What is a 4-Cylinder Turbo Engine?

A 4-cylinder turbo is an engine with four cylinders that line up with the next one, forming a straight line. These are often called “inline 4” or “I4” engines. Every 4-cylinder turbo is a smaller engine, typically with a displacement of less than 3 liters (3.0L) compared to a V6. This means the combustion chambers hold no more than 3.0L of air collectively among the four cylinders.

Because of the lower displacement, 4-cylinder engines are:

• More fuel efficient
• Smaller than a 6-cylinder
• Less toxic to the atmosphere with fewer emissions

The turbocharger is what makes an I4 engine truly stand out. It works by forcing exhaust back into the cylinders, which creates bigger explosions as the pistons pump air into the cylinders. The result is more power and higher horsepower in larger engines that can outrun comparable V6 engines.

What is a V6 Engine?

A V6 engine is one in which the 6 cylinders are aligned in the shape of a V. These were common in larger cars and light-duty trucks until larger engines with bigger displacements became more common. A V6 engine is one that is naturally aspirated, using only the air and fuel it pulls in during the original cycle of the piston pressurizing the cylinder.

A V6 engine can:

• Produce low RPM torque for towing
• Create higher horsepower at lower displacements
• Have more air in the chamber to produce bigger explosions

The downside is that the V6 isn’t as fuel-efficient as an I4. 

What’s the Difference Between a 4-Cylinder Turbo and a V6 Engine?

The first major difference between a 4-cylinder turbo and a V6 engine is that the I4 has two fewer cylinders. Secondly, the turbocharger forces more air into each cylinder. Third, a 4-cylinder turbo requires high-octane premium (93 octane rating) gasoline to run. Another major difference between a 4-cylinder turbo and a V6 engine is that the turbo engine also requires full synthetic oil for the best results to keep the turbocharged parts cleaner for longer periods of time.
