3.7 Engine .... Any Good?????

Hi Boys and Girls,

Some of you may be aware that I'm a proud owner of a 5.7 Ltd XH Commander here in the United Kingdom (England).

I'm now looking for a part time play thing, and have my eye on a 08 Dodge Nitro 3.7SXT. Do the Dodge Products i.e The Nitro run the same motor & transmission to that of the 3.7 Commander?

If so, how do you rate the 3.7 engine & transmission for power, torque, build quality and reliability?

In addition, how is the Nitro seen as a credible SUV in the USA (and other countires).....

Nitros are like miniature Commanders.

I have the 3.7V6 in my Commander, but that might not give you the info you need, since I'm guessing the Commander is a heavier vehicle than a Nitro. But the 3.7V6 does just fine for what I need, which is mainly just transporting people. I have had 6 adults, a car-carrier full of luggage for 6 people, and an 8-foot Uhaul loaded with crap on an 8-hour trip, and it didn't even act like it noticed the extra weight. I personally think it's a strong little V6.

It's probly even more noticeable in a Nitro.

Reading the spec sheets over here, it looks like the Commander and Nitro are similar weights!!!

We used to own a 2005 Liberty with the 3.7, now we have a 2007 Commander. Both with the 3.7 V6. The 3.7 is a very well built engine, and has done Jeep well. I feel it is better matched to the Liberty than the Commander because of the vehicle weight. We chose the base Sport with the V6 for cost, but we are happy with it. If I want to go out and "play", I would use my '97 Wrangler anyways -43

You got me interested, so I looked, too... they're similar, but the Nitro is a little lighter. It runs 3900-4100 lbs... the Commander runs 4700-5200 lbs, so it can be almost 1000 lbs more.

Nitros look really similar to Commanders from behind. There's been a few times I got fooled.

The 3.7L is a very good engine. It provides plenty of torque so it’s very adequate for off-road use and even when towing.

The downside of the 3.7L is street/expressway driving when you want acceleration. The Commander is heavy, and the 3.7L accelerates noticeably more slowly compared to the 4.7L and 5.7L.

The big difference I see is that you have the “pedal to the metal” a lot more when driving a 3.7L. That negates any savings in mileage with the smaller 3.7L engine.

It's just fine if you slow down.

had one in my 07 Liberty with a 6spd man. and it was a strong 6 banger we just didn't like the bumpy ride of a short wheelbase and the amount of room it had. The liberty and the Nitro are built on the same platform too, So i'd imagine they'd be very identical all the way around...hope this helps

I think you are right. The Nitro and Liberty are clones that are made to look slightly different.

Also from Cars.com, this makes me go, "hmm..."

The Nitro is not intended for rugged trails, although with its H3-like styling it looks as though it should be.

"The Jeep buyer takes his vehicle and sits on the edge of the Grand Canyon, enjoying nature," Dodge truck marketing manager Ron Zarowitz said during last year's rollout of the Nitro. "The Dodge customer is an on-road driver."
Is the Liberty available in the UK? Might be a better bet than the Nitro if you want to do a lot of off-roading.
