Luxury Diesel SUV Comparison 04 We just missed the five-friend cut, so would having four real chums make us eligible for a very good life? Gathered before us is a collection of diesel-powered midsize SUVs that manages to strike an even keel between capable off-roader, luxurious long-hauler, and excellent all-weather family transporter/urban warrior. It's quite the specific niche. Two newbies lead off: The Jeep Grand Cherokee EcoDiesel and Porsche Cayenne Diesel are the fresh faces whose base vehicles debuted in 2011 but didn't deliver a diesel engine for a few years. Then there's the Volkswagen Touareg TDI, the pack's longest-running contender. Its current model also came out in '11. Rounding out the bunch is the Mercedes-Benz ML350 BlueTec, an associate of the vaunted M-Class that helped spur the luxury SUV market's expansion upon its release in 1998. Luxury Diesel SUV Comparison 03 Like a tight-knit group of friends, the foursome enjoys a common bond: They all possess 3.0-liter turbodiesel V-6 torque monsters producing an identical 240 hp and drive all four wheels through 265mm tires, but each has its own background, pedigree, and personality. Naturally, the Porsche and Volkswagen arise from a shared family lineage nearly 10 years old. They both have their own set of high expectations: The first Touareg was Motor Trend's 2004 SUV of the Year, while the second iteration of the Cayenne was the 2011 winner. Yet they couldn't be more dissimilar. The original M-Class was our '98 Truck of the Year (the award predated the first SUOTY by a year) and is presently in its third generation ('12 and forward). Likewise, the Grand Cherokee was the '93 TOTY. More than a decade after the honors, Jeep experimented with a different diesel for a grand total of two years. It was known as CRD, for Common Rail Diesel, from 2007-2008. We predict Jeep will stick with its EcoDiesel for more than two years.
Luxury Diesel SUV Comparison 01 Luxury Diesel SUV Comparison With four vehicular friends in town, we did what any pals would do. We went out. We stumbled around Southern and Central California and saw some sights. We took pictures. We ended up at the Hollister Hills State Vehicular Recreation Area for off-roading. There may have been yelling and shouting. And after spending lots of quality time, we believe we've come up with four friend archetypes that relate to the 'utes. Mr. Iacocca may have tagged the great life at five friends, but these stout-hearted four will follow you through thick and thin.
The Ones Who Couldn't Make It
Let's settle the issue right off the bat and explain the absence of the Audi Q7 TDI and BMW X5 xDrive35d. The Q7, as a seven-passenger SUV, competes in a different category, and the X5 is entering its new F15 generation, meaning it wouldn't make sense to include a challenger that already has one leg out the door. We hope to see both again sometime soon.
The Ambitious One
Some of your ambitious friends set high but attainable personal goals, and others get waylaid by pipe dreams. The VW Touareg TDI is the former. 2013 Volkswagen Touareg TDI Front Three Quarter In Motion Truck Trend executive editor Allyson Harwood declared, "That such a competent vehicle placed fourth in my order says a lot about the quality of the SUVs in this comparo." That's the truth, and we'd expect many consumers to be immensely satisfied with the Touareg. It rides on the stiffer end of the luxury spectrum, but not uncomfortably so, a consequence of its steel-spring suspension -- it's the only 'ute here without air springs. Selectable Off Road mode features exceptionally well-programmed Auto Hill Descent Assist, and the 6.9-second 0-60-mph time lands it in a three-way, first-place tie with the Mercedes and Porsche. 2013 Volkswagen Touareg TDI Rear Three Quarters With a long list of features and an easy-to-use interior, the Volkswagen ticks the right boxes for a $50,000 SUV. And after a 900-mile group driving adventure, the observed 26.7 mpg ranked it second in fuel economy behind its Cayenne cousin. A 4992-pound vehicle achieving that figure is a testament to the power of diesel. Our primary problem with the Touareg TDI is that we remember its predecessor. The 2004-2010 Touareg was a truly remarkable performer with 4Motion four-wheel drive and available air suspension and adaptive shock absorbers, making it more of a one-stop shop than the present-gen model. The VW didn't stand out in any way in this company, driving and feeling as anonymous as its loud engine note, which has a soundtrack seemingly burned from the "Generic V-6 Engine Noises, Compilation Volume 1." (Is it any consolation that the Cayenne has the same sound?)

Our more petite evaluators felt the driver's seat base cushion needs to be shortened so their legs would hinge less awkwardly over the edge. Associate online editor Karla Sanchez logged, "I kept shifting positions to try and find a sweet spot, but it was just impossible to get comfortable." Ambition can be a potent tool, but trying to live up to a past SUOTY victor calls for an even greater helping of agility.
The Reserved One
This is the friend who always has more on his mind than he lets on. He's outwardly shy, analytical, and always has some random, out-of-the-blue factoid that makes you go "huh." The vehicle equivalent is the Mercedes-Benz ML350 BlueTec. 2013 Mercedes Benz ML350 Bluetec 4Matic Front Three Quarter In Motion Like our nonchalant human friend, the ML350 doesn't feel it necessary to shout its piece. Its all-aluminum V-6 offers the most torque in the test -- 455 lb-ft -- but the real eye-opener is how it sounds. The Mercedes' engine is by far the most muffled, sounding like a distant direct-injection gasser only when being wrung out from the driver's seat. While it stands the tallest among the four (1.4 inches higher than the Jeep at normal ride height), Sanchez judged it the best to drive on-road: "It was my favorite on the curvy roads and highways. Felt light on its feet, and was the most effortless to maneuver." Part of its road behavior can be attributed to the standard Agility Control self-adjusting dampers, $1610 Airmatic air suspension, and $2910 Active Curve System (a set of adjustable anti-roll bars that disengage for straight-line driving and engage when cornering to limit roll). 2013 Mercedes Benz ML350 Bluetec 4Matic Rear Three Quarters In Motion The thinking buyer who craves refinement will be extremely satisfied with this M-Class, savoring everything from the gargantuan cargo space (38.2 cubic feet expands to 80.3 when the backseat is lowered) to the classy, airy cabin to the dignified, calming ride.
The ML350's all-aluminum V-6 offers the most torque in the test -- 455 lb-ft
As well as the ML350 BlueTec drove on paved roads, we considered it the most out of place on the Hollister Hills trails. Not that it did poorly. Associate online editor Nate Martinez said, "It's no hard-core off-roader with multiple modes and cool screens to look at, but it is a very capable soft-roader."

Harwood elaborated, "The Mercedes really never felt comfortable on the trail, and while it did what it was supposed to, it complained and made odd noises while it worked." The "odd noises" would be the ABS pulses we occasionally heard and felt when the hill-descent control system was active. The ML350 was the only SUV that groaned off-road. But the biggest disappointment was the fuel economy. According to the EPA numbers, the Benz's 20/28 mpg city/highway (impressive in its own right for a 5109-pound lux 'ute) is enough for third-best in the closely rated pack. The second-"lightest" SUV systematically generated the lowest observed mpg over the three distinct legs of our 900-mile romp, finishing the journey with 25.3 mpg.
The Well-Bred One
Bless their hearts, but friends who come from better-off backgrounds sometimes just don't get you. They might be the most well-meaning people in the world, but their perspective on things doesn't sync with yours. This brings us to the Porsche Cayenne Diesel. 2013 Porsche Cayenne Diesel Front Three Quarters In Motion Without an imposing naturally aspirated or twin-turbo V-8 in the engine bay, the athletic Cayenne could be expected to lose some of its luster, right? Wrong. The second-thriftiest Cayenne on sale today is a magnificent sport/utility vehicle, replete with the familial, 406-lb-ft turbodiesel V-6 found in the Touareg TDI, smooth-shifting eight-speed automatic transmission, beautifully appointed innards, and bump-conquering air suspension.
If the 911 were a sport/utility, it would be the Cayenne
And did we mention the fuel economy? With an observed 29.2 mpg, the Leipzig, Germany-assembled 'ute effectively stole the other three's lunch money before shoving them to the ground in this metric. To ensure we hadn't made a calculating error, we checked the numbers twice, noting the Cayenne categorically elevated itself in the mpg order in all three drive loop sections. So either we had a freakishly efficient Porsche, or it really is that good. 2013 Porsche Cayenne Diesel Rear Three Quarters In Motion Matched to the efficiency are the innate handling reflexes dialed into every Porsche. Harwood: "If the 911 were a sport/utility, it would be the Cayenne." It's a hoot to blast around on winding roads, plus the Cayenne reminds us more of what the Touareg used to be than the current Touareg with regard to off-road worthiness. Your senses meld with the vehicle, creating too much fun for something of this size. Interior ergonomics issues, the least spacious confines, and narrow outward visibility knock the functionality rating down several notches, the effect amplified by the fact that the Cayenne is an SUV and should at least try to act like one. "The central driveline tunnel is populated by a mesmerizing amount of buttons. Quickly finding what you're looking for usually doesn't happen -- even after four days living with it," noted Martinez.
It stole the others' lunch money in fuel economy

The Jeep is essentially loaded to the gills at its base cost of $56,990, but the Cayenne Diesel doesn't have its $3980 air suspension with height adjustment and Porsche Active Suspension Management or $1330 off-road underbody protection at its $57,575 starting price. The chosen options on our Porsche outnumbered the other three SUVs combined, bloating the as-tested price to eye-popping levels. Not that we think your average Cayenne customer is swayed much by pricing in the first place.
The Right Hand
You may as well call this one your bestie. Your best friend "gets" you in every way and isn't judgmental. You trust this person. You'd also trust our Jeep Grand Cherokee EcoDiesel. 2014 Jeep Grand Cherokee Ecodiesel Front View In Motion Its full legal name is the 2014 Jeep Grand Cherokee Summit 4x4 EcoDiesel, and it's here to set a new standard for all Grand Cherokees. The latest GC is technically still in the same generation (2011-now), but has been considerably refreshed. Apart from the all-new powertrain -- a VM Motori-sourced diesel engine paired with a gem of a ZF-sourced eight-speed automatic -- the cabin received the most prominent revamp. Open-pore wood trim on the topline Summit model complements the inspiring digital gauge cluster (with a screen dedicated to wheel articulation!) and infotainment touch-screen display. The previous arrangements looked like something the better part of 10 years old. Harwood: "The real difference was inside, though, where the materials and the color scheme are much more upscale and the interface is downright intuitive. Things are within easy reach, easy to learn to use, and work as they're supposed to." There are quality leather and plastics, too. Years of interior suffering make the transition even sweeter.
This one is here to set a new standard for all Grand Cherokees
2014 Jeep Grand Cherokee Ecodiesel Rear The Grand Cherokee is the lone wolf here with true four-wheel drive, as evidenced by its two-speed transfer case that features a 2.72:1 low-range ratio. It felt perfectly at ease roaming Hollister Hills and still had plenty of off-road capability to burn. There might be some differences in assumed on-road performance because differing brand perceptions, but our critics found the Jeep held its own against the premium German marques just fine. Martinez thought the GC "had one of the most comfortable interiors of the quartet."

The Jeep was the heaviest in the comparison, weighing 279 pounds more than the next-closest diesel-slurping sled. Yet the GC found itself trading fuel-economy punches with the ambitious Touareg, closing the test cycle at 26.4 mpg, 0.3 off the VW's. Let's not forget the GC is carrying more dedicated off-road hardware. The extra poundage endows the Jeep with a disadvantaged weight-to-power ratio that results in the slowest acceleration (7.8-second 0-60 mph). But if speed is your game, perhaps you're reading the wrong story.

Fret not, for the engine is quiet and vibration-free during normal running. With 3.5 turns needed from lock to lock, it requires you to put in more steering input than do the other 'utes. The steering feels slow on the streets, but you realize the benefit in the dirt. It's a good trade-off. For a segment-friendly $56,990, you get world-class equipment and world-class on- and off-road performance with loads of space for the family and all of your junk. As Iacocca once said, "If you can find a better car [SUV, in our case], buy it."
4th: Volkswagen Touareg TDI ;A generally good SUV, but it simply doesn't feel as good as it once was.
3rd: Mercedes-Benz ML350 BlueTec; Perfect for the diesel luxury SUV buyer who also abhors the idea of diesel.
2nd: Porsche Cayenne Diesel; It'll burn up back roads more quickly than it'll burn though a single tank.
1st: Jeep Grand Cherokee Summit 4x4 EcoDiesel; Capability, character, class, and content. The hallmarks of a winner.
