2017 Jeep Grand Cherokee Trailhawk V-6

The Jeep Grand Cherokee is pretty much tops among mid-size SUVs when the road beneath isn’t actually a road. That said, there’s a difference between being capable of performing a task and being purpose-built to master it. And while every Wrangler is born to play in the dirt, none of the 10—yes, 10—different Grand Cherokee models offered for 2016 were configured specifically for the activity upon which Jeep built its brand. Such a model seems like a no-brainer, if for no other reason than to give Renegade Trailhawk and Cherokee Trailhawk drivers something to move up to. But more important, it would nod to Jeep’s avid off-road enthusiasts, some of whom may be aging, adding offspring, or for whatever reason might find the Wrangler Unlimited a bit too spartan. Jeep certainly has had the know-how (and most of the existing parts) to build such a thing all along, and it came to pass with the unveiling of the 2017 Grand Cherokee Trailhawk last spring. Now, we’ve tackled trails in one, drove it to our West Coast base, and conducted our instrumented testing.
This isn’t the first time Jeep has offered the Grand Cherokee in Trailhawk form; such a version first appeared as a 2013 model, boasting the Grand Cherokee’s most sophisticated off-road components, a generous but not lavish level of creature comforts, and stylistic flourishes equivalent to jeans and a flannel shirt. At around $42,000, the 2013 price was reasonable enough that folks who spend their weekends in a tent by a campfire still might afford it. But the Trailhawk quietly disappeared when the facelifted 2014 model arrived.

The Dirty Parts

As before, the Trailhawk starts with the best off-road gear in the Jeep pantheon: the Quadra-Drive II four-wheel-drive system with its two-speed transfer case and Selec-Terrain dial, along with an electronically controlled limited-slip rear differential, hill-descent and -ascent control (HDC), a full gamut of skid plates, and Jeep’s nifty off-road app. The standard air springs can rise to provide up to 10.8 inches of ground clearance (0.4 inch more than any other air-spring-equipped Grand Cherokee) or lower the vehicle to ease ingress and egress. The rolling stock is no joke: Kevlar-reinforced 265/60R-18 Goodyear Wrangler All-Terrain Adventure all-terrain tires wrapped around aluminum wheels with matte-black inserts.
Our test example was powered by FCA’s ubiquitous 3.6-liter Pentastar V-6, making 295 horsepower and 260 lb-ft of torque, with an eight-speed automatic doing the shifting. The 360-hp 5.7-liter Hemi V-8 and the 3.0-liter turbo-diesel V-6 with 240 horsepower and 420 lb-ft of torque are available as well.

Statement Styling, Cavelike Cabin

The Trailhawk’s mission is evident at first glance. Chrome has been banished from the headlamp bezels, grille, mirrors, roof rails, bumpers, and badges in favor of argent gray or black, while two red tow hooks and matte-black hood decals visually tie it to other Trailhawks in Jeep’s portfolio. Some of us could do without the hood stickers, but the Trailhawk is still handsome, even in our example’s bright Redline Pearl paint—a tough color for a big SUV to pull off. And there’s something about a lack of chrome that makes a truck look good when it’s dirty.
Things are even more intense inside, where pretty much everything other than some chrome trim pieces and red stitching is rendered in solid black (the only color available). The Trailhawk borrows several items from higher up the Grand Cherokee food chain, such as a 506-watt premium sound system and FCA’s 8.4-inch Uconnect touchscreen infotainment unit, although by far the best upgrades are the deeply bolstered front sport seats from the Grand Cherokee SRT, upholstered here in leather and microsuede. Our example also boasted a $450 UConnect navigation upgrade and the $2695 Trailhawk Luxury package that adds HID automatic headlamps, LED fog and running lights, a power-adjustable steering column, and a panoramic sunroof.

Trailhawk On- and Off-Trail

On a winding, closed, dirt course that Jeep charted through the Santa Monica Mountains, we were able to see how the whole package comes together. Not surprisingly, the Trailhawk handled everything we tossed its way, from traversing body-bending staggered ruts to climbing steep, silt-covered hillsides to navigating down even steeper slopes on the back side. With HDC’s combination of hill-ascent and -descent control—the off-road equivalent of cruise control—the Trailhawk kept a steady pace over all but the craggiest of rocky paths while those awesome seats anchored us firmly in place. The most remarkable aspect of driving on that diverse terrain was how little we had to think about it. And while it may never feel natural to keep one’s foot off the brake pedal during steep descents (especially when hanging from the seatbelts and seeing nothing but earth through the windshield), our inability to match the steadiness of the hill-descent control on our own while descending a particularly steep grade vividly illustrated the technology’s benefits.

The Numbers

Off-road-oriented vehicles usually perform more poorly than their on-road counterparts in our instrumented tests, and the Trailhawk is no exception. Powered by the same engine and weighing within 100 pounds of a 2016 Grand Cherokee Summit V-6 4x4 we previously tested, this Trailhawk was a half-second slower to 60 mph, at 7.6 seconds, and trailed by the same amount in the quarter-mile (15.9 seconds and 88 mph). Manual shifts yielded our best times, as the eight-speed automatic tended to upshift well short of the V-6’s redline. We also learned to activate the Sport mode upon startup, which adjusts shift points and throttle settings to keep the 5077-pound beast on a fleeter footing, even if it dragged our observed fuel economy down to an abysmal 15 mpg.
Other objective test numbers also were lackluster. The Trailhawk’s 198-foot 70-mph-to-zero braking distance is 17 feet longer than the Summit’s, and its 0.71-g skidpad figure trails the Summit’s 0.76 g (which itself is nothing to boast about). Blame the tires—the Kevlar-reinforced rubber doesn’t exactly claw a paved road, resulting not only in compromised performance but vague steering, too. On the flipside, ride quality is firm yet remarkably civilized for anything so capable, and the tire noise at highway speeds is scarcely any louder than that of more street-friendly rubber.

The 2017 Trailhawk starts at $43,990—the third cheapest of the 10 Grand Cherokee models for 2017—which is $1700 less than the cushy Overland but $5100 more than the Limited. The price swelled to $50,125 once the aforementioned extras were added, plus another $900 for Mopar roof rails, $595 for blind-spot warning and rear cross-traffic detection, and $1495 for the Jeep Active Safety package (adaptive cruise control, forward-collision warning, lane-departure warning, and parallel/perpendicular parking assist). Although it seems like a hefty sum, at least you get even more capability to go with the additional tech and creature comforts. And maybe the Trailhawk will stick around for more than one year this time.

2017 Audi A4 Allroad

When the previous-generation Audi Allroad replaced the A4 Avant in the U.S. model range for the 2013 model year, sales increased by 50 percent. Yes, hard-core Audi aficionados went ballistic about the lack of a regular A4 wagon—or A4 Avant in Audi-speak—but understand that a regular station wagon isn’t what the American car-buying public purchases. While many people, including us, would prefer the lower, sportier wagon it offers in Europe, Audi is also in the business of selling vehicles and making profit. So, when the newest, B9-generation A4 range launched earlier this year, it was an easy decision for U.S. product manager Anthony Garbis to skip the regular wagon and go right for the Allroad, now carrying the A4 moniker as well.
This Allroad follows the formula that brought two predecessors, the A6 Allroad and the B8-generation A4-based Allroad to our shores: Lift a wagon, install permanent roof rails, and slap on some chunky body cladding. That’s oversimplifying the task but isn’t completely off base. The modest 1.3-inch lift comes from both longer springs and dampers (0.9 inch) and slightly taller all-season Continental ProContact TX radials (0.4 inch). The roof rails are aluminum and stout enough that they might serve as tow hooks. The cladding adds no width to that of a standard A4, even if it looks as if it does. Even better, the add-ons aren’t just raw plastic. Garbis, with a hint of pride in his voice, confirms that the two-tone Allroad’s tack-on bits are painted matte black, an expensive process, we’re told. Those who hate the two-tone look can get the plastic painted to match the body color for $1575. (The monotone option itself costs $1000 but is offered only with metallic paints that add another $575 to the sticker.)

Quattro Goes Ultra

The only other attribute that makes this Allroad special is its new all-wheel-drive system, marketed as Quattro with Ultra Technology. The Ultra business of this system dumps a center differential for a pair of clutches, one at each end of the rear axle’s driveshaft. Under most conditions, the Allroad functions as a front-driver for a slight bump in efficiency. Not spinning the driveshaft saves precious drops of fuel, and said shaft can be reengaged in as little as 0.2 second. While it is an understandable step toward meeting CAFE regulations, we also see it as a heretical departure from the traditional all-wheel-drive Quattro canon. Expect the system to appear in other Audis, although all S and RS models will continue to use center differentials.
Except for the new all-wheel-drive system, the powertrain is a direct carryover from the A4. A 2.0-liter turbocharged inline-four with cam phasers and variable exhaust-valve lift makes 252 horsepower and 273 lb-ft of torque. Ratios are swapped via a dual-clutch automatic with paddle shifters for manual gearchanges, if that’s your thing. The seven forward ratios are identical to those in the A4, but a shorter final-drive ratio (4.41:1 versus 4:23:1) combats the resistance of taller tires and the claimed 199-pound penalty for the wagon bodywork. The A4 Allroad is more than capable of keeping up with the briskest traffic, and we expect it to return a launch-control-assisted zero-to-60-mph time in the mid-five-second range.

A+ Accommodations

Those familiar with Audi’s most recent interiors will feel comfortable in the Allroad. Solid black is available, but the two-tone interiors are especially rich in appearance and feel. In the $44,950 Premium trim model, analog gauges fill the binnacle behind a pleasant and well-contoured steering wheel. Those who want the 12.3-inch, full-color Virtual Cockpit with its configurable gauges and driver-oriented screen will have to select the Premium Plus trim ($3000) and its Technology package ($3250), which also includes navigation, an 8.3-inch center screen, and blind-spot monitoring. Other Premium Plus upgrades include a 19-speaker, 755-watt Bang & Olufsen sound system, front and rear parking sensors, proximity-key entry, LED headlights, and 4G LTE connectivity and its associated in-car Wi-Fi. The standard panoramic sunroof’s perforated sunshade is one of very few interior oversights—it doesn’t effectively block out the sun.
Fully loaded Prestige models require a $7400 upgrade from the base car and include all the Premium Plus and Technology package items, plus a full-color head-up display, acoustically insulated front-side windows, and a multi-camera setup with 360-degree “Top View” functionality to ease low-speed maneuvering fore or aft.
The Allroad sweet spot seems to be a Premium Plus car with the Technology and Cold Weather packages (heated seats and steering wheel, $500) and the Sport package, which includes the A4’s supportive 12-way sport seats for another $500, totaling $52,200. That’s a few grand more than Audi charges for a similarly equipped Q5 crossover, but there are a few bells and whistles on the Allroad that aren’t available on the Q.

Not Much Penalty for Lifted Suspension

Raising the car a little more than one inch doesn’t do much to erode the driving dynamics of the already proficient A4. Unlike the slightly sloppy on-center wobble we found in the A4 sedan’s steering, the Allroad’s tracks straight and true, no matter what Drive Select mode is engaged, and the brakes deliver inspired feedback without so much as a hint of sponginess. Among Comfort, Auto, Dynamic, and Individual modes, we found Auto to do everything well. The steering goes overly light in Comfort mode, while choosing Dynamic cranks the firmness of the adaptive dampers beyond what a pseudo SUV requires. Auto is the “just right” porridge for this backwoods bear.
The only mode the Allroad offers that isn’t in the A4 quiver is Offroad. When selected, steering effort is reduced and Quattro engages the driveshaft all the time (with some clutch slipping when turning to avoid driveline binding). Offroad mode also changes the adaptive damping and disables the forward-collision warning and impact intervention so as not to inadvertently stop the car from hitting a tree you weren’t going to hit anyway. We drove the Allroad down 90 miles of Wyoming logging roads and engaged Offroad some of the time. As was true on paved roads, the Auto mode seemed to work just as well as Offroad mode. You might see greater benefit to Offroad mode in deep snow or on particularly icy roadways.

Lots of Room, Less Consumption than an SUV

Remember that mention of fuel economy? The reality is that EPA ratings give the new A4 Allroad a 1 mpg advantage over its predecessor on the combined scale (25 mpg), with the city rating up just 2 mpg (23 mpg) and the highway figure unchanged at 28 mpg. The Volkswagen Group may have tightened its EPA-reporting leash—well, at this point it might as well be a noose—for the 2017 model year, so any improvement greater than marginal might be hidden. We’ll learn more when we can test one on familiar roads. The good news for the A4 Allroad’s sales ambitions is that its combined-fuel-economy rating tops the Q5’s by more than 10 percent.
Open the power rear hatch (which can be operated by wiggling a foot under the bumper in Allroads equipped with the Technology package), and the standard cargo cover automatically lifts out of the way to reveal a 24-cubic-foot compartment. There also is a divider to protect back-seat passengers from loose items, and the seatback folds in 40/20/40 sections for maximum versatility. Drop the seats all the way and there are 59 cubic feet to fill. When the back seats are in place, they’re plenty comfortable for two adults, with ample head and knee room. Fitting three would be a squeeze, but it’d be doable over a short distance.

Living up to its name, the A4 Allroad is unlikely to meet a mapped road it can’t negotiate, even if few owners will attempt anything more daring than making use of the extra ground clearance while trekking through deep snow. An SUV is an obvious solution for this scenario, but in a world rapidly filling with crossovers, the distinctive Allroad faithfully keeps the wagon torch lit. Those driving an SUV now may discover how much they miss truly carlike dynamics once they encounter the real thing again in the Allroad. Maybe Allcar would be a better name, because this is really all the car most people need.

2017 Chevrolet Camaro SS 1LE Manual

Let’s cut right to the hyperbole: The 2017 Chevrolet Camaro SS 1LE is a rolling manifestation of Bruce Springsteen’s most celebratory lyrical fairy tale, the “all-American boy with a nose for trouble finds his way by means of a pushrod-V-8–powered muscle car with a weary but naturally beautiful girl in the passenger seat.” Born from the same humble two-door-coupe blueprint that launched the Camaro50 years ago, it’s the everyman’s super-Camaro: a 455-hp, apex-craving monster that rings in with a $44,400 base price ($6500 for the SS 1LE Performance package on top of $37,900 for the 1SS coupe). That’s $16,435 less dear than the expected $62,135 sticker for the 2017 Camaro ZL1, and it will likely undercut the price of the upcoming 2018 Camaro Z/28 by even more. While we’re talking matters of finance, the only other option on our test car was a performance data recorder for $1300, which brought the as-tested price to $45,700. It may not be free, but it’s at least attainable for most aspiring part-time track rats.

Decoding 1LE

Regular readers may recall that, over some 15,000 miles, our long-term 2016 Camaro SS has proved itself to be a comfortable cruiser as well as an extroverted destroyer of tires. Although it’s otherwise similar, the 2017 Camaro SS tested here is further equipped with the vaunted 1LE package, a collection of performance and cosmetic upgrades aimed at putting a sharper edge on all the attributes that make our long-term SS such a blast to drive. (For 2017, the 1LE package is also available on 1LT and 2LT V-6 models, but this review focuses on the V-8–powered SS.)
The $6500 1LE package includes a comprehensive list of hardware. Key items include an FE4 performance suspension with specific tuning for the springs, anti-roll bars, and magnetorheological dampers (GM’s Magnetic Ride Control); Brembo six-piston front monoblock calipers and four-piston rear calipers (painted red); aluminum-hat and iron-friction-surface rotors; an electronically controlled limited-slip, 3.73:1 differential; a six-speed manual transmission; a dual-mode performance exhaust system; and a track cooling package with engine, transmission, and differential coolers. Tasked with keeping the car in contact with the pavement are Goodyear Eagle F1 Supercar 3 tires constructed with a rubber compound developed specifically for the Camaro. Sized 285/30ZR-20 in front and 305/30ZR-20 at the rear, the imposing tires wrap 20-inch Satin Graphite forged-aluminum wheels (10 inches wide up front, 11 inches at the rear).
Telltale cosmetic items include an aggressive-looking fascia and grille with a larger splitter plus a rear blade spoiler; the aero aids are rendered in the same satin black as the hood wrap. The interior features a head-up display and Recaro front buckets, while the flat-bottomed steering wheel and the shift knob are both wrapped with a soothing synthetic-suede material that feels great under your fingers.

Hardware Wars

Before we get into the nitty-gritty details of how this hit parade of Chevrolet performance parts translates into test results, let us remind you of how well this sub-$50K Camaro SS 1LE performed at this year’s Lightning Lap competition at Virginia International Raceway. In Turn One, its 1.11 g of grip matched that of the Ferrari 488GTB, and in the uphill esses it managed a higher average speed (121.6 mph) than the McLaren 570S. Do we really need to tell you how many 1LE Camaros you could buy for the price of either of these exotics? Ultimately, the Camaro posted a lap time of 2:54.8, earning it a second-place ranking in the hotly contested LL2 class ($35,000 to $64,999). Only the 526-hp 2016 Ford Mustang GT350R lapped the circuit faster, shaving an even three seconds off the 1LE’s time. With a base price of $63,495, the Stang cost $6365 extra for each of those three seconds. (It’s worth noting that the V-6 Camaro 1LE took first place in the sub-$35K, LL1 class.)
With all those racetrack heroics in mind, let’s take a look at how the 1LE fared in our standard round of tests: The zero-to-60-mph run consumed 4.1 seconds, and the quarter-mile arrived in 12.4 seconds with the car clearing the traps at 116 mph. Although the Camaro was equipped with launch control, our drivers beat it by utilizing old-fashioned reflexes, launching the car with the engine spinning around 2000 rpm for the best results. Braking and roadholding prowess, the primary focus of the 1LE tweaks, catapult the Camaro beyond the sub-$50K pack. Once warmed up, the brakes consistently hauled the 3747-pound 1LE to a stop from 70 mph in just 141 feet with no fade, and a lap of our 300-foot skidpad revealed 1.05 g of grip. Those figures meet or beat those posted by the significantly more expensive 2016 Chevrolet Corvette Stingray Z51 (149 feet, 1.05 g) and the only mildly more expensive 2016 Ford Mustang Shelby GT350 (171 feet, 1.00 g) as measured in arecent comparison test.
While the numbers are impressive, they don’t relay how innocuous the SS 1LE can be in day-to-day driving. Sure, the Recaros are snug, but they leave enough room for your limbs to move about and take care of business. The compromised outward visibility makes it somewhat difficult to place the car on the road, but most staffers eventually acclimated to the environs. Mountains of torque available all over the rev band—the peak of 455 lb-ft comes at 4400 rpm—ensure there’s no need to blip the throttle when letting out the clutch pedal to move away from a stop, which is handy in stop-and-go traffic jams. The magnetorheological dampers manage to soften the impacts transmitted by those massive tires. Hard as it may be to believe, highway slogs are not only possible, they’re pleasant; the 1LE even measured an acceptable interior noise level of 72 decibels at a steady 70 mph.
But when the urge to cut and run arises, the full might of the 1LE package is at your service. The steering is direct and precise, the shifter feels instantly familiar, and the brake pedal is firm and linear in operation. Together, they conspire with the chassis to transform a meat cleaver into a scalpel, a vehicle that immediately responds to and rewards the slightest inputs. The Camaro is endowed with so much grip and stopping power that it’s nearly impossible to find public roads to explore anything more than a fraction of its capabilities. Stable and confident, it inspired even novice drivers to push a little harder on our 10Best Cars test loop, so clearly does the chassis telegraph its behavior. At the risk of drawing major-league hate from both camps, one driver likened its reassuring demeanor to that of a “big, fat Miata.” Let us assure you this was meant as a compliment of the highest order.

There are caveats: Like all Camaros, outward visibility is poor, the rear seats are all but pointless, the interior lacks any substantial provisions for stowage, and the trunk opening is barely large enough to swallow a gym bag. But there are plenty of staid, sensible vehicles that excel at those tasks. This one is fast, brash, and wears its underdog legacy as a badge of pride. You’ve gotta respect that, even if you hate Bruce Springsteen.
