#JeepCherokee

Fiat Chrysler Automobiles is flinging cash at its Midwestern assembly plants as part of its world-conquering plan to boost Jeep production.

Yesterday, the automaker announced $1.05 billion in funding to retool its Belvidere, Illinois and Toledo, Ohio production facilities, and issued a kill date for one of its least popular products.

More than 300 jobs are coming to a historic Toledo manufacturing site, and you can thank the car-buying public’s thirst for Jeeps for it.

Dana Holding Corp. is spending $70 million to build a 300,000 square foot axle plant at the former Willys-Overland site, with Jeep being its only named customer, Automotive News reports.

The Jeep brand is Fiat-Chrysler’s biggest money maker, so it’s no wonder that CEO Sergio Marchionne is scattering factories around the world like a sailor’s offspring.

The company’s head honcho outlined his business plan for the brand in an interview published by Automotive News, and it involves no longer having to make a “Sophie’s Choice” decision with Jeep output.

Examples of the XJ Jeep Cherokee are everywhere in Denver junkyards (nearly as numerous as late-1990s Subaru Outbacks, these days), and it takes a special one to make me deploy my camera. I thought the factory-installed orange tape stripes on this ’91 Cherokee Sport were interesting, and now today’s ’93 with innovative tree-branches-and-rattlecans camo job has made the cut.

Because we still see them all over the roads today, the still-in-production ( in China) XJ Cherokee is the best-known Jeep Cherokee. However, AMC made a two-door version of the original SJ Wagoneer, called it the Cherokee, and built it for the 1974 through 1983 model years (just to confuse things, a four-door SJ Cherokee was added to the mix a few years into production).We saw an XJ Cherokee Junkyard Find a couple of weeks ago, and here’s a final-year-of-production SJ from the same Denver self-service yard.

The XJ Jeep Cherokee was made for approximately a thousand years (OK, 32 years, counting the still-in-production BAW Knight S12), and these trucks are still extremely easy to find here in Colorado. Nice XJs still command good prices here, but used-up ones fill the local wrecking yards. Since I shared a junked Grand Cherokee last week, it’s only fair that we should admire a discarded Colorado Cherokee Sport.

She seduced my soul.

She is a a 1989 Jeep Wagoneer with just over 200,000 miles and a fantastic maintenance history. With beautiful, thick leather seats and a working A/C system which is a huge deal here in Georgia, the old woody Jeep could only have been better if it had a stick and a four-wheel drive system mated to its iron-block 4.0-liter inline-six.

I started the bid at $700, a dealer who specializes in the Latino clientele bid it at $800, and then another fellow jumped in at $900. By the time bidding was at $1100, I waited a few seconds, and did a slicing motion with my hand which knocked it up to $1150.

Would I get it?

In each of the last three months, the Cherokee has been the best-selling model at America’s fastest-growing volume brand. Jeep sales are up 44% in the United States through the first eleven months of 2014, an improvement of 191,895 units.

Excluding the Cherokee, which wasn’t on sale until the fourth-quarter of 2013, Jeep sales are still up 10% in 2014 and 15% in November. Those Cherokee-less increases still far outpace the auto industry as a whole, which is up a little more than 5% this year; a little less than 5% in November.

Yet even before Jeep once again broadens its lineup with the subcompact Renegade, the Cherokee helped power the brand to new heights. The Jeep brand last topped the 500,000 mark in calendar year 1999. Jeep sold 629,074 utility vehicles during the first eleven months of 2014.

On a percentage scale, through the first seven months of 2014, the only auto brand improving its year-over-year U.S. sales tally more proficiently than Jeep is Maserati. In other words, Jeep is the fastest-growing volume auto brand in America in 2014.

Based on pure volume gains, no auto brand, certainly not Maserati, has improved on its seven-month 2013 sales total as successfully as Jeep has, with 120,708 extra sales over the last seven months.

The Jeep Grand Cherokee received a diesel option earlier this year, but don’t look for the Cherokee to get one any time soon – at least not in North America.

For a brief stretch of time, Jeep did business in the UK as a purveyor of authentic American SUVs. The Cherokee, Wrangler and Grand Cherokee had a respected niche, even if they didn’t sell in particularly large numbers. And then it all went down the tubes.

You may not have heard the name Roy Lunn, but undoubtedly you’ve heard about the cars that he guided into being. You think that’s an exaggeration? Well, you’ve heard about the Ford GT40 haven’t you? How about the original XJ Jeep Cherokee? Lunn headed the team at Ford that developed the LeMans winning GT40. Later as head of engineering for Jeep (and ultimately VP of engineering for AMC) he was responsible for the almost unkillable Cherokee, Jeep’s first unibody vehicle, a car that remained in production for over two decades with few structural changes and could be said to be the first modern SUV. In addition to those two landmark vehicles, Lunn also was in charge of the engineering for two other influential cars, the original two-seat midengine Mustang I concept and the 4X4 AMC Eagle. If that’s not an impressive enough CV for a car guy, before Ford, he designed the Aston Martin DB2 and won an international rally. After he retired from AMC, he went to work for its subsidiary, AM General, putting the original military Humvee into production. Oh, he also had an important role in creating one of the most legendary muscle cars ever, the Boss 429 Mustang. So, yeah, you should know about Roy C. Lunn.

The problem with a “take-no-prisoners” approach to evaluating new cars is that when you’re the only one adopting a particular stance, it can get pretty lonely – even your own readers begin to doubt you. My initial review of the Jeep Cherokee was a great example of this. Most reports are fairly positive – and indeed, there was plenty to like about the car, as my own review mentioned – but many of the car’s flaws were glossed over or simply not mentioned. On the other hand, we at TTAC gave you the unvarnished truth about the Cherokee – and Chrysler was gracious enough to let us review the Cherokee again.

A TTAC reader is an engineer with a major powertrain company, and offered his extremely detailed analysis of the ZF 9-speed. Consider this an AP level course in powertrain engineering.

Before we dive right in to the 9-speed gearbox, let’s take a quick refresher on the basics of gears. The simplest gear set consists of 2 parallel gears mounted on 2 parallel shafts. Shown in Fig. is a gear set with a 20 tooth drive gear on the right and a 30 tooth driven gear on the left. For this gear set the speed of the driven gear is 1.5 times lower than the drive gear, and assuming no frictional losses anywhere, the torque on the driven gear is 1.5 times higher. This gear set has a ratio of 1.5:1. This type of a gear set is usually not favorable for packaging since it requires 2 parallel shafts, and there are largest separating forces that push the 2 gears apart which means that the bearings supporting the shafts have significant radial loads on them, in addition to an axial load if the gears are helical.

The folks at Jeep have known for some time that high volume on-road models have to be part of the mix to keep low volume off-road models viable. From the 1946 Willys Station Wagon and the original Wagoneer, to the Grand Cherokee and the Compass, Jeep has been on a steady march towards the word no Wrangler owner wants to hear: “crossover”. Their plan is to replace the off-road capable Liberty and compete with the RAV4, CR-V and 20 other small crossovers with one vehicle: the 2014 Cherokee.

With two ambitious (and contradictory) missions and unconventional looks, the Cherokee has turned into one of the most polarizing cars in recent memory. It is therefore no surprise the Cherokee has been getting mixed reviews. USA Today called it “unstoppable fun” while Consumer Reports called it “half baked” with a “choppy ride and clumsy handling.” Our own Derek Kreindler came away disappointed with its on-road performance at the launch event, though he had praise for the Cherokee’s off-road capabilities. What should we make of the glowing reviews, and the equally loud dissenting voices?
