Which is best, a V6 or a V8? This query could appear outdated to some on this age of turbocharging, hybrids, and electrical autos. Nevertheless, it’s nonetheless related, significantly when searching for a truck or SUV.

Engine Anatomy: What’s the “V”?
The essential perform of an inside combustion engine (ICE) relies upon upon the movement of pistons to rotate a crankshaft, which in flip powers the wheels by way of a gearbox. Pistons might be of assorted sizes, however every accomplishes its activity inside the confines of a cylinder. In easy phrases, the extra pistons, the better the ability potential. Consequently, once we confer with the variety of cylinders in an engine, it’s actually in regards to the variety of pistons.
Engine designers can organize the cylinders in a straight line (inline) or divide them into two parallel rows with an equal variety of cylinders. When divided into two rows, the cylinders should be angled inward at their base to connect the pistons to the crankshaft working alongside the underside heart of the engine. In different phrases, the parallel rows of cylinders type a “V” form.
Though you would discover inline-8 engines in a number of fashions 60 or 70 years in the past, in the present day, the inline association is confined to engines with six or fewer cylinders. These with eight or extra cylinders and most with six cylinders are within the V configuration.
The benefits and drawbacks of inline versus V is one other story for one more time.
What’s a V8 Engine?
Two rows of 4 cylinders every comprise a V8 engine. Typically, V8 engines are bigger, heavier, extra fuel-thirsty, and extra highly effective than V6 engines.
Why You Want a V8
The explanations for selecting a V8 differ relying on whether or not it’s a automotive as an alternative of a truck or SUV.
No less than in the intervening time, a V8 is the selection for many drivers searching for high-performance or horsepower and torque from a automotive. Whether or not a coupe, sedan, unique, or sports activities automotive, the V8 usually stays the go-to engine. Carmakers providing V8s usually reserve them for his or her top-end fashions.
Effectively suited to efficiency vehicles, V8s not solely provide the next energy ceiling, however they ship that energy in a easy, linear development. What’s extra, they emit a fierce growl that engines with fewer cylinders merely can’t duplicate.
Vehicles providing a V8 are a quickly shrinking slice of the automotive pie. Muscle vehicles and high-performance sports activities vehicles are a number of the final V8-equipped vehicles standing.
Take a look at these examples of high-performance V8 vehicles:
2022 Chevrolet Corvette: 6.2-liter V8 – 490 hp/465 lb-ft torque
2022 BMW Alpina B7: 4.4-liter twin-turbo V8 – 600 hp/590 lb-ft torque

2022 Mercedes-Benz AMG E63 S Sedan: 4.0-liter twin-turbo V8 – 603 hp/627 lb-ft torque
Vans and SUVs
Whereas the V8 vs. V6 debate for vehicles primarily revolves round efficiency, it’s extra about cargo-carrying capability and most towing limits in vans and SUVs.
Typically phrases, V8s deliver the next capability for energy (energy ceiling). A V8 is extra succesful for those who want your truck to tug or haul heavy masses usually and for prolonged intervals. These further two cylinders sharing the workload means the stress of pulling a heavy load over lengthy intervals will get lessened for all of the cylinders.
Though V6 engines are gaining floor, V8s nonetheless rule amongst full-size vans and SUVs. That is significantly true when used for work and towing.
Take a look at these examples of vans and SUVs providing V8 engines:
2022 Ford F-150: 5.0-liter V8 – 400 hp/410 lb-ft torque

2022 Jeep Grand Wagoneer: 6.4-liter V8 – 471 hp/455 lb-ft torque
What’s a V6 Engine?

Furthermore, some type of a V6 even provides the go for a rising variety of efficiency vehicles.
Take a look at these vehicles with a V6 on the prime of their engine meals chain:
2022 Nissan GT-R T-Spec: 3.8-liter twin-turbo V6 – 565 hp/467 lb-ft torque
2022 Audi A5 RS 5 Sportback: 2.9-liter twin-turbo V6 – 444 hp/442 lb-ft torque
2022 Kia Stinger GT: 3.3-liter twin-turbo V6 – 368 hp/376 lb-ft torque

As for towing, the V6 outshines the V8 within the above instance. The V6 can tug as much as 14,000 kilos, whereas the V8’s most towing capability is 13,000 kilos. Nevertheless, because of the V8’s better dimension and weight, we’re again to that sustained energy benefit V8s usually provide over V6s.
So, until your truck or SUV goes to be an actual workhorse, you’ll in all probability admire the decrease working and restore prices of a V6. Additionally, you will nearly at all times pay much less at buy for a V6.
