Agreed with your post. I drove the Compass Trailhawk over the weekend.

It is a nice engine-gearbox combination; if it was introduced along with the Compass' original launch, the car would easily be doing ~2000 units / month consistently. But Jeep killed its potential by bringing it too late & that too on the Trailhawk variant only. I hope that the rumoured lower variants that this gearbox is coming in will be priced well.

The drive is smooth and it'll suit the relaxed driver. The brilliant engine also has enough torque on tap. But Fiat doesn't have that brilliance in tuning AT gearboxes (I say this after driving the Compass Petrol AT too). At times, I found it hard to believe that it's a ZF. Many times, it would upshift when I didn't want it to, and downshift at others. Sometimes, it stayed in 2nd gear for longer than expected. Found the gearbox "hunting" in tricky traffic conditions too.

Still, overall this is a capable AT SUV, with the price & size being the main points against it. As things stand today, my favourite Compass remains the Diesel MT which is quite a rockstar.

Just wanted to add that the dead pedal is horrible. It's way too narrow. The dead pedal didn't bother me as much in the MT as it's not used as much there. But in the AT, my left foot started aching after resting the left leg on the dead pedal for 45 - 60 minutes.

Default Offroading with the Jeep Compass Trailhawk

Update on my most recent drive. This time I played around with the cruise option all the way.

The Trailhawk has explosive performance in the cruise resume mode. The higher the cruise was set at the faster the acceleration. I just felt that FCA are running different maps for the cruise control.

Every time you brake ,the cruise dis -engages , you then hit the resume button and then the Trailhawk is a different beast. It will still take that one second to choose the right gear and kick down, and then the full torque surge and the 170 horses seem to be all available.

The acceleration and up shifts happen really quick. The first few times I was actually struggling to hold the suv( torque steer I guess or just surprised?)

In the cruise resume mode this SUV transforms itself into another beast. I am now enjoying my highway drives a lot better and the smile has been plastered across my face ever since. No points for guessing which steering buttons will be the most worn out on my Compass.

Hope I was able to time it but maybe another day when I have a buddy around and not my wife.

Just completed 4500 kms. A long drive (1400 kms round trip)down south helped. Enjoying the tank.

I am assuming this can be achieved in a Limited 4x4

Superior Approach / Breakover / Departure angle: There is a huge improvement in the approach (26.5), breakover (21.2) and departure (31.6) angles.

This continues to be an Achilles heel, whats the possibility of retrofitting Trailhawk Bumper on Limited 4x4 ?

Skid Plates: Trailhawk has high-grade, heavy-duty steel and high-quality black e-coated skid plates covering the cooling module, engine, transmission oil pans, front suspension and fuel tanks.

Again I believe this would be an easy add-on for the with Limited 4x4


Improved water wading depth: The Trailhawk’s water wading depth is 483 mm, which is much improved compared to the 330 mm of the other variants.

How exactly is this achieved ? Did they change anything in the engine Bay and exhaust Plumbing ?


It would be really great if you can respond to this

Naive question but it seems like the issue is when all four wheels lock up and the car still slides down - shouldn't the Hill Descent Control pump the brakes here to let the wheels rotate and give you steering control again?

Also, in such instances, I assume the fundamental problem is that the tyres don't have the grip to hold the vehicle on the slope so wouldn't the same thing happen with a proper crawling gear?

I don't know the answers to these. One of the owners has to try it.

HDC behaves exactly like ABS. And ABS is not a good thing in offroad driving. Ask any offroader who has taken ABS equipped SUV into slippery trail.

When the tyres keep rotating, it doesn't easily slip. Let's say the braking tyre slips when coefficient of traction is at 5, but the rotating tyre slips when coefficient of traction at 2, giving you lot more room to work with it.

Interesting! It seems in principle possible for an ABS mode that accomplishes precisely this by allowing some rotation to "mimic" a crawl gear - but I suppose it hasn't quite been figured out yet.

Regarding the water wading, I'm assuming they have relocated the air intake level as well as moved essential electronics higher?

I wouldn't say exactly like ABS where it pumps the brakes at approx 15 times a second. HDC uses ABS sensors but the braking forces are different. If it behaved just like ABS, then the point of HDC would be moot and it'll be HCD - Hill Crash Down!

Well, HDC uses ABS, just the frequency and modulation is different as the application is different.
