Re: Ordering my TRAILHAWK

It's not funny math, it's different testing procedures.

Canada is still using old EPA test (2 cycles - 60 mph top speed). New EPA test has 3 additional tests to better simulate real-world driving...

Re: 2014 GC 3.6L V6 enough?

I'm aware of it, but the overall gear ratios are much more useful.

I meant to say that my quote stands for the V8 also.

Grand Cherokee V8 overall gear ratios
......8 speed.....5 speed

Re: 2014 GC 3.6L V6 enough?

3 - 3.0L CRD Diesel
5 - 5.7L Hemi
6 - 6.4L Hemi

Re: 0-60 times JGC V6 & V8

Gear ratios play a significant role. All 5 speed vehicles (Charger, 300, GC, Durango) lack a real first gear. SRT's are exception because of an aggressive final drive ratio.

Re: 0-60 times JGC V6 & V8

LR4 had a shorter 1st gear (like 2014 JGC) and was quicker 0-30 mph (2.2 - 2.6 sec). At 0-50 mph they were equal (5.2), but at around 50mph JGC shifts into 2nd and revs fall from 5500 to 3000 rpm. ...

Re: 8-speed transmission

Looking at the gear ratios provided by Jeep, it should be (according to my calculations):

HEMI - 1700 rpm
Pentastar, CRD - 1900 rpm
SRT - 2050 rpm

Re: Diesel People - Enlighten Me? (2014)

As a result of the GM-Fiat divorce, GM got rights on 1.3L and 2.0L Fiat diesel engines, and Fiat got $2 billion. Fiat will buy GM's stake in VM Motori in the next 12 months. GM will continue diesel...

Re: $1000 + price increase for 2013 Jeep SRT8

@Strada
Why is $90.500 ridiculous when similarly equipped BMW X5 M retails for $160,000?
