Jeep Grand Cherokees are majorly built as rear-wheel drives with off-roading capabilities; they can also be used for towing and hauling loads.

Cherokees are relatively spacious and they are, of course, reliable – both the V6 models and V8 models. However, the V8 models deliver better performance on/off road.

That said, let’s quickly compare between Jeep Grand Cherokee v6 vs v8 in detail!

Jeep Grand Cherokee V6 vs V8: The Comparison

Choosing between engine options is one of the most challenging decisions to make when buying a brand new Cherokee.

With V6 engine, you’d be paying a cheaper price, but why not add up and have a V8 engine installed for you? Here’s what you should know.

1. Fuel Efficiency and Engine Performance

If you care more about saving fuel as you drive, a V6 engine would give you higher fuel efficiency. The base V6 engine in Cherokees is a 2.4L four-cylinder that delivers 172hp and 165 lb-feet torque.

Another optional V6 engine for Cherokees is a 3.2L engine that produces 271Hp and 239 pound-feet of torque.

On the other hand, the V8 engine available for Cherokees is a 5.7L HEMI V8 engine that produces 360 HP with 390 lb.-ft torque. You’d get 19mpg – 24mpg with the V6 engines and 14 – 22mpg with the V8 engine. Apparently, you’d save more fuel with the V6 engine.

2. Towing Capacity

Basically, V8s are built for towing; they are “heavy-duty” engines with extreme sturdiness for hauling.

For Jeep Grand Cherokees, the towing capacity of the V6 engines is 6,200 lbs. maximum, while the V8 engine allows you to tow up to 7,200-pound weight. If you’d be towing large campers or any other heavy “stuff,” V8 engine is the better choice.

3. Off-Roading Capabilities

Both the V6 and V8 engines can take you through any off-road path; yes, they are both built strongly, however, the V8 engine would let you drive seamlessly on rough, rocky paths.

A Grand Cherokee with a V8 engine would give you more stability when you drive through paths that are quite rocky.

4. City Driving

Well, the V8 engine wins the comparison for off-roading, but for city driving, the V6 engine is the best. The V6 engine is lighter and provides more stability while drifting on city roads.

Also, V8s do not accelerate as fast as V6s; if you love cars that accelerate quickly, the V6 engine is a perfect option.

5. Noise Level

Typically, V8 engines produce throaty, deep sound when you rev or accelerate; a lot of drivers love this sound, but some other driver do not like it. Also,

V6 engines are less noisy when driving; so, if you love quiet driving, you may just have to pick a Cherokee with the V6 engine option.
