Acura MDX vs. Audi Q7 3.0T, BMW X5 xDrive35i, Land Rover LR4 HSE, Lexus GX460

Acura MDX vs. Audi Q7 3.0T, BMW X5 xDrive35i, Land Rover LR4 HSE, Lexus GX460

The words “coast to coast” have very specific connotations when they appear in this magazine. The Cannonball Baker Sea-to-Shining-Sea Memorial Trophy Dash, for one. Not this time. Do you see any California beaches in these photos? Any Red Ball Garages?

The coasts visited on this tour do lie on vast bodies of water, but the water is fresh (so to speak) and defines the eastern and western boundaries of  Michigan’s Lower Peninsula.

So, rather than the 2798-mile blitz from New York City to Redondo Beach, California, as in the original Cannonball Run, our coast-to-coast dash was a little more modest—135 miles, from Alpena on Lake Huron at the east to Traverse City, tucked into Grand Traverse Bay off Lake Michigan, on the west. With some dirt-road diversion, plus the trek from and to Ann Arbor, it added up to 650 miles. Which seemed like enough. More than enough, in at least one of  these vehicles.

There were five, and their classification isn’t quite as easy as their shapes might suggest. We’re tempted to call them crossovers, but for all its elasticity, that word can’t stretch quite far enough to cover the Lexus GX460. One of the guides we use in identifying crossovers is their construction—unibody  versus body-on-frame, usually based on front-wheel-drive passenger-car architecture. The 460’s body doesn’t catch up with its chassis until late in the assembly process. Which makes it a truck.

For that matter, even though the four others are unibodies—frame rails integrated with the body structure—the front-drive passenger-car connection is pretty much absent.

We also look at towing capacity. Vehicles rooted in front-drive architecture tend to be relatively anemic as draft animals—usually 4000 pounds max—but even that simple rule of thumb fails us here. The Acura MDX, which traces its ancestry to the front-drive Honda Odyssey minivan, has the lowest rating in the group, but it’s a respectable 5000 pounds.  And the max capabilities range up to the Land Rover LR4, pegged at 7716.

In the end, we settled for a classification based on one inarguable attribute: three-row seating. Not very snappy. But accurate. You could add the word “luxury” because that, too, is accurate. The ­amenity quotient is high across the board, and so are the prices. The as-tested ticket for each member of  this quintet is well above $50K, soaring to a max of  more than $67,000.

With snow in the forecast, we climbed into our three-rows and set out for Michigan’s northeast coast, right where the index finger would poke up through the mitten of the Lower Peninsula. Suffice it to say, Dom DeLuise won’t be starring in this movie, but that doesn’t mean it wasn’t entertaining.Continued...

2013 Infiniti JX Crossover

2013 Infiniti JX Crossover

Infiniti’s EX and FX crossovers are a hoot to drive, but as showroom performers, they’re the Microsoft Zunes of the automotive world. Crossovers like the Lexus RX and Acura MDX trounce the duo’s combined sales by tremendous margins every month in the charts. The execs at Infiniti are well aware of this, and are preparing the three-row JX to properly mount an assault on the luxury-crossover market.

Through the garbage-bag garb of this prototype, we can make out an Infiniti grille that may even beat that of the M sedan for bulginess. The roofline of the car in these photos is clean and elegant, tapering towards the rear into the oval-shaped rear window like those of the EX and FX. The design seems very far along—perhaps it’s even finished—and in profile, the truck is somewhat reminiscent of the low-slung Audi Q7. There isn’t a lot you can do to disguise seating for seven.

Infiniti Badge, Nissan Roots

Unlike the rest of the current Infiniti lineup, which depends on just two rear-drive-based platforms—one for the G, M, EX, and FX, and a second for the QX—the JX will borrow a front-drive-based Nissan platform. (Our guess is the architecture from the Altima and Murano.) The bosses at Nissan and Infiniti haven’t yet spoken to the degree of differentiation between the JX and any Nissan siblings, but we expect the Infiniti to be something more than simply a stretched and rebadged Murano.

Our spy photographer also got a clear shot of the JX prototype’s interior, and the car shows both its Nissan roots and some Infiniti-style touches. The layout of the center stack is clearly dependent on what you’ll find in the Nissan Murano, with a centrally mounted display flanked by air vents. The gearshift lever is similar to what you’d find in other Infinitis, though, and you can also spot the same knob on the center console, situated between the seat-heater controls, that controls chassis settings on other Infinitis.

As we previously reported, Nissan has filed paperwork with the U.S. Patent and Trademark office to trademark JX20, JX25, JX25h, and JX30. Which—if any—of these badges will one day adorn JX crossovers on the road is difficult to say. Infiniti’s current naming convention indicates the engine displacement in liters multiplied by ten, and we have a hard time believing the company would sell a three-row crossover SUV with a 2.0-liter or 2.5-liter engine—at least in the States. What’s more, Nissan doesn’t even have a 3.0-liter engine in the parts bin right now, save a diesel six offered in a few Renaults. In spite of there not being a trademark filing for JX35, we think the crossover is most likely to receive Nissan’s ubiquitous 3.5-liter VQ V-6, which produces in the neighborhood of 290 hp in most of its front-wheel-drive applications. Given Nissan’s proclivity for rubber-band transmissions, a CVT may be the only transmission on offer.

That’s where the speculation ends. In showing off its sketch in New York, Infiniti laid out its timeline for the JX: It will show a concept version at the Pebble Beach Concours d’Elegance in August, and follow that with a production vehicle at the L.A. auto show in November. Expect more information as those dates near.

2014 Infiniti Electric Sedan

2014 Infiniti Electric Sedan

What it is: A sleek luxury sedan designed as a dedicated EV.

Why it matters: If EVs become a success, Infiniti will—for the first time—be a leader. The other luxury brands, after all, only make hybrids.

Platform: The Infiniti will be built off the Nissan Leaf.

Powertrain: The Nissan Leaf motor, likely tuned to make between 130 and 150 horsepower, powered by lithium-ion batteries, driving the front wheels through a single-speed transaxle. The range should be better than the Leaf’s real-world 80 miles.

Competition: Fisker Nina and Tesla Model S (if they are ever produced).

What might go wrong: The Infiniti EV will be a good-looking, well-appointed sedan, but the question remains whether more than a few customers will be ready to put up with a diminutive range, long charging hours, mediocre performance, and a huge price premium.

Estimated arrival and price: Mid-2013, more than $40,000.

2013 Infiniti JX Concept Sketch

2013 Infiniti JX Concept Sketch

We appreciate Infiniti’s forthrightness in announcing a sixth model for the American market. The company is using the occasion of the New York auto show to tease us with a sketch of the seven-passenger JX crossover, while a concept will appear at the Pebble Beach Concours d’Elegance in August and the production version will bow at the L.A. auto show this November. Glad that’s out of the way. The rest of the details, however, are still murky.

To wit, the watercolors-meet-blur-tool rendering shows a metal-trimmed sidelight opening that sweeps back into a kinked D-pillar, a treatment very similar to the one on Infiniti’s recent Etherea concept. (That same kinky look was also used on Infiniti’s too-hot-for-production Essence concept.) Muscular fenders and flowing body lines match the rest of Infiniti’s current lineup, save for the more blocky QX56. Fortunately for the JX, by way of its two-box shape, it doesn’t appear to suffer from the which-way-is-it-heading problem the Etherea did.

There’s no official word on what will motivate the JX, but trademark filings we uncovered last summer provide some hints. Infiniti has secured the rights to the JX20, JX25, JX25h, and JX30 badges, suggesting a lineup that could include four-cylinders, V-6s, and a hybrid. It’s doubtful that all four would be offered, with the more likely explanation being Infiniti’s desire to safeguard the alphanumerics for possible future use. The hybrid, however, is almost a guarantee, if not from the start.

An all-wheel-drive option also is a given, although the JX may be the first Infiniti in a long while to be based on a front-drive architecture instead of a rear-drive platform. If that is in fact the case, we won’t be surprised if Nissan gets its own version of the large crossover.

We also won’t be surprised when the expected concept looks nearly production-ready. If we don’t know much about the JX, at least we know exactly when we’ll know more. Look for more details at Pebble this summer.

2012 Infiniti M35h , M Hybrid - Drive

2012 Infiniti M35h , M Hybrid - Drive

As the first in-house hybrid from Nissan/Infiniti, the M35h is pretty unassuming. Indeed, although the test cars we drove in Japan were covered with decals advertising their gasoline-electricness, small “hybrid” badges on the production models’ front fenders will be the biggest powertrain giveaway once the cars arrive stateside next spring.

Now, before you frothily remind us that Nissan already has a hybrid in the Altima, remember that it uses technology licensed from Toyota, a complicated system with two electric motors and a planetary CVT. The M hybrid takes a simpler, Nissan-engineered approach to integrating electric power. Like the latest hybrids from Hyundai, Porsche, and Volkswagen, the Infiniti’s single electric motor is located between the engine and automatic transmission, in place of a conventional torque converter. The 67-hp motor is connected to the crankshaft via a wet-plate clutch. This allows the M to use its 1.3-kWh, 340-volt lithium-ion battery pack for electric-only propulsion at speeds up to about 60 mph as long as the driver keeps throttle application below 20 percent. During deceleration, the system will turn the engine off and decouple it from the driveline at speeds as high as 81 mph, as opposed to simply shutting off the fuel supply, which means some amount of energy is still being spent.

Should you need more power than the electric motor can supply, the gas-powered engine will kick in, although a second, dry clutch in front of the rear differential slips when the car changes from electric to gas mode to help smooth out any potential jolts. Nissan uses the designation VQ35HR for the 3.5-liter V-6 in the M35h. Technically, it’s the same engine that’s used in the EX35 (as well as in the M35 and G35 in previous model years), but in this application, the output is 302 hp and 258 lb-ft of torque. Infiniti is short on details as to all the ways in which this engine differs, but we do know that the M35h’s V-6 has different cam timing and uses the late-intake-valve-closing Atkinson cycle for greater efficiency.

It’s a Hybrid, So It’s Heavy

There’s always a catch with hybrids, of course, and that catch is weight. In the M35h, the penalty is 265 pounds compared with a conventional M37, which Infiniti claims is 66 fewer pounds than the toll exacted by the Lexus GS450h’s hybrid system. That means the M35h should weigh in around 4300 pounds. The extra low-end torque provided by the hybrid system should offset the extra heft; we predict a 0-to-60-mph time of 5.5 seconds, the same as that turned in by the M37 in a recent comparison test. Of course, as in most hybrid sedans, the M35h’s battery pack sits behind the rear seats, compromising trunk space.

Our brief drive of a right-hand-drive, Infiniti-badged Nissan Fuga (as the M is known in Japan) suggests that the M37’s solid handling has been preserved, especially in the braking and steering departments. The only herky-jerky event we encountered was from mashing the accelerator pedal at low speeds. A jolting downshift from the seven-speed automatic transmission was followed by a second surge as the electric boost was routed to the rear wheels. We experienced the aggressive engine shut-off, too, as we observed the revs drop to zero while humming along at 70 mph. It’s easy to stay in electric mode, although we’ll have to wait until a stateside drive of the production car to see if the M35h keeps up in traffic without using the gasoline engine.

Infiniti claims the M35h has fuel economy close to that of a 1.8-liter economy car. If the M hybrid can match the numbers of an automatic-transmissioned Nissan Versa (which, conveniently, is available with a 1.8-liter engine), it would achieve EPA figures of 24 mpg in the city and 32 mpg on the highway. That would be an improvement of 6 mpg over the M37 in both categories, which seems reasonable considering the Infiniti’s bias toward performance and the lofty mileage numbers achieved by the Ford Fusion and Hyundai Sonata hybrids.

Oh, and there’s another catch with hybrids, and that is price. Again, Infiniti is short on details, but we expect the M35h to sit between the M37 and M56 in the product lineup. We’re also guessing the base price will be closer to that of the M56 than its V-6 counterpart, or about $53,000. Lexus has had a hard time moving many copies of the slightly more expensive (and performance focused) GS450h, and we aren’t going to predict significant sales for the M hybrid just yet. But we can already tell this Infiniti will be more fun to drive than the Lexus.

2012 Infiniti M35 Hybrid - Info

2012 Infiniti M35 Hybrid - Info

Japanese manufacturers have been leading the hybrid movement from the beginning, but so far Nissan’s only entry has been the Altima hybrid, which licenses its powertrain from Toyota and is only sold in eight states. Now, shortly after announcing the Leaf electric car, Nissan tells us that its Infiniti luxury arm will be getting into the hybrid business with the 2012 M35 hybrid debuting at the Geneva auto show.

While the company is currently being coy with performance and fuel-economy estimates, it's calling the M35 the “cleanest and most economical car in Infiniti’s history.” With technology previewed by the Infiniti Essence concept from last year's Geneva show and now coined Infiniti Direct Response Hybrid, the M35 hybrid will feature a 3.5-liter V-6 augmented by a 67-hp electric motor fitted between the engine and a revised seven-speed automatic transmission. There is no conventional torque converter. The rear-wheel-drive-only car will be capable of moving solely under electric power, although Infiniti is keeping quiet on how far or how fast. The company claims that its 1.3-kWh laminated lithium-ion battery is the same size as a nickel-metal-hydride battery pack, but with twice the power, and that the use of manganese for its positive electrodes improves the battery’s temperature stability and, therefore, overall reliability.

The 2010 Infiniti M will go on sale in the spring of 2010, with the hybrid to follow about a year later as a 2012 model.

2012 Infiniti M35h Hybrid

2012 Infiniti M35h Hybrid

Infiniti has announced that its first-ever hybrid model, the M35h, will start at $54,575 when it goes on sale at dealers in mid-March. This seats the 360-hp M35h squarely between the $47,925 M37 and the $59,325 M56.

It’s difficult to compare the M35h’s price to competitors’ because, quite simply, there aren’t a whole lot of ‘em. The aged Lexus GS450h starts at $58,925, and can muster an EPA fuel-economy ratings of only 22 mpg city/25 highway against the Infiniti’s 27/32 rating. Mercedes-Benz’s diesel E350 Bluetec represents an alternative approach to fuel sipping; it undercuts the M35h at $51,850 (although the Infiniti is much better equipped), and is good for an EPA-estimated 22 mpg city/33 highway. It’s worth mentioning that Audi soon will have a hybridized A6 on the market, too, although it hasn’t been confirmed for U.S. sale.
