The day has finally come. The call to Storm Area 51 on September 20 started out as an Internet joke but has inspired hundreds of people to actually drive out to the area surrounding the top-secret Nevada militarybase in search of alien lifeor at least a good party. We strongly recommend that you don't storm Area 51 if you want to stay out of jail, but all this Alienstock hype brings back fond memories from this 2018 comparison test, when we carried out an Area 51 raid of our own in five high-performance SUVs. Enjoy! The craft came to a stop in a cloud of dust. A slender figure emerged from inside the swoopy, sleek sheetmetalloose skin, bulbous head, humanoid but with a hint of something extra and a swarm of scientists descended,needingfeedback. Needing data. Needing to know: Have we finally broken through? Ihave always been fascinated with Area 51. Stories of secret test flights, of government scientists collaborating with alien pilots to push the limits of what we believed possible, hooked my childhood mind. And seeing Capt. Steven Hiller pilot his F/A-18 through the Grand Canyon, flying saucer in hotpursuit, only solidified my intrigue ( Independence Day s fictional nature notwithstanding). Was that top-secret area in southwest Nevada really the place where the government had hidden the Roswell aircraft? Had we reverse-engineered spacecraft not of this earth, perhaps with alien aid? Or werethe feds telling the truth whentheysaid the facility was merely the development site for military jets such as the U-2, SR-71, and F-117 Nighthawkjets that suspiciously flew higher, faster, and sneakier than any before? Like those military jetsor flying saucersthese five ridiculously high-performance SUVs we are pilotingrefuse to conform to classical ideas of appearance and capability. Originally created for rock-crawling or helping out around the estate, sport-utility vehicles have become Americas favorite mundanefamily haulers. But somehow, in a recent unexplainable technological leap,SUVs have also evolved into supercars, with overboosted engines stuffed between their fenders and suspensions cranked down for sports car levels of performance. This is higher, faster, sneakier space-alien stuff. Which is how our pack of otherworldly vehicles is screaming at post-apocalyptic velocities across Nevadas Extraterrestrial Highway. What better place to find answers on the hottest transport advancements than Americas most secret environs? So we rip a hole through the desert air, alien experimentation on our minds, in a 2,730-hp convoy of performance SUVs built by manufacturers that have thrown out their rulebooks. The 503-hp 2018 Mercedes -AMG GLC 63 S 4Matic+ Coupe Im piloting is a challenge to the automotive status quo. SUVs dont need to be big and slow; sports cars dont have to be light, low, and lean. Like it or not, SUVs are where the auto industry is going. With its twin-turbo V-8 making 516 lb-ft of torque mated to a nine-speed auto with all-wheel drive, I cant say I mind this form of transport. Coming from brands traditionally known for their off-road prowess, the 2018 Jeep Grand Cherokee Trackhawk and 2018 Land Rover Range Rover Sport SVR both turn their backs on knobby tires and mud slinging in favor of a pair of supercharged V-8s. The Rovers new-for-2018 5.0-liter unit makes 575 hp and 516 lb-ft of twist and is paired with an eight-speed automatic and a full-time four-wheel-drive systemits vestigial link to its past. The Jeep , in a nod to the nuclear wasteland that is the Nevada Test Site surrounding Area 51, goes all in with its 6.2-liter Hellcat V-8, which puts out an absurd 707 hp and 645 lb-ft of torque. The Grand Cherokees engine is abetted by an eight-speed automatic and an all-wheel-drive system. Meanwhile, the 2018 Alfa Romeo Stelvio Q4 Quadrifoglio and 2017 Porsche Macan Turbo with Performance package are a weird, roundabout return to the roots of the two storied racing brands. The Stelvio packs a Ferrari -derived 505-hp 2.9-liter twin-turbo V-6 under its hood, and its backed by an eight-speed automatic and all-wheel drive. The Macan rides on an Audi -developed platform, but its 3.6-liter twin-turbo V-6 is all Porsche . It packs 440 hp and 442 lb-ft of torque, and its backed by Porsches famed PDK seven-speed twin-clutch gearbox and torque-vectoring all-wheel drive. The stakes here are high, and Im really pondering the idea of a 440-hp Porsche being the lowest-output beast of this bunch. The winner of this performance SUV comparison test will have the honor of being the first SUV to compete in our annual Best Drivers Car competition next month. As such, the rules are simple: The winner needs to be the most engaging, exciting, fun-to-drive super SUV in our quintetthe SUV thats most likely to upset the world order. Welcome to Earth The scenery a day earlier couldnt be more different. A twin-turbo V-6 growls in front of me as the sapphire blue Macan slices through soupy coastal clouds and mist as we climb the Angeles Crest Highway to meet up with the rest of the group. Its been a while since Ive driven a Macan; this one offers an extra 40 hp, larger front brakes, and a few other go-fast options. It feels the same as the Turbo without the Performance package, but Angeles Crest will be the place to prove it. The highway twists and turns 66 miles up and over the San Gabriel Mountains as it links the L.A. basin to the Mojave Desert and beyond. Its the perfect nearby-substitute for the Best Drivers Cars State Route 198 hill climb. Once linked up with the rest of the crew, we picked one of our favorite stretches of the highway and set off. The Porsche makes things easy. Despite the Macan having the least powerful engine here, I found myself parked on the Trackhawks tail as we rocketed up Angeles Crest for our first run of the day. The Macan is easy to drive fast. Zuffenhausen did a fabulous job with the suspension, senior features editor Jonny Lieberman said. The damping is superb, and the body control is excellent. But theres something off about the Porsche. Its not in the way it drives, but in the way it makes you feelor not feel, rather. Theres a sort of numbness to the Macan Turbo thats tough to identifythe Novocain-numb steering is part of the issue, but theres more to it. Although this crossover is supremely capable, I found myself daydreaming about bills to be paid and errands to run. Nearly every other editor felt (or didn't feel, as the case may be) the same detachment. Theres no doubt about its capability, but theres just no emotion in it, features editor Scott Evans said. Driving a good car up a good road is supposed to be an escape. The Macan wasnt acting like one. Seeking a shot of adrenaline, I swapped into the Darth Vaderblack Range Rover Sport SVR for my next run. I have fond memories of the pre-refresh Rover Sport SVR. Although its short 25 horsepower compared to the new one, it was absolutely hilarious to drivethe only SUV as prone to swinging out its backside as it was to plowing through a bend. It took all of four corners to discover that the SVRs manners have finally been tamed. I havent decided if thats a good thing, but because youre no longer fighting the Rover, you do get a chance to evaluate its prowess in other areas. Not nearly as ridiculously tail happy as the last SVR, this iteration does feel noticeably smoother, Jonny said. The Range Rover Sports steering rack has a surprising delicacy and lightness to it, given the Rovers size, but its air suspension cant keep up on a good road. Its weight is noticeable on the twisties, where it leans quite a bit, associate road test editor Erick Ayapana said. The Jeep Grand Cherokee Trackhawk has a lot in common with the Rover. Theres a lot to love about the Trackhawk, but in this group it turns about as well as a B-2 in a dogfight. Its steering feel is actually pretty responsivedirect, linear, mechanicalbut its dragstrip-oriented suspension makes it feel like, well, a Jeep. I ran out of desire to go faster long before I ran out of grip, associate online editor Collin Woodard said. As Scott would discover, braking could be a bit of an issue when the Jeep was pushed hard. In a few miles, I managed to set the brakes on fire, he said. Not smoking. Actual flame from the right front pad. The Jeep sports decent-sized brake rotors; we suspect that higher-quality brake pads and fluids would help avoid small, easily extinguished fires like we had. (Note: Pushing heavy vehicles repeatedly to their limits can ignite the brakes, and although its rare, it is not unheard of in the testing community.) If youre only looking to figuratively set your world on fire, the Alfa feels like it comes from a different galaxy than the Rover and Jeep. The Stelvio is a crossover only in that it looks like the rest of the SUVs assembled here. From behind the wheel it feels like its sedan stablemate, the Giulia Quadrifoglio, with an extra carbon-fiber halfshaft driving the front wheels. The body control on this high-rider is incredible, Scott said. Collin agreed, adding, From the moment you take off, everything just feels right. Thirty seconds in, I almost forgot I was in a crossover. It might sound like hyperbole, but the Stelvio really manages to capture the engaging, dynamic feel of the Giulia sedan (warts and all), from its pure steering to its grabby, hard-to-modulate brake-by-wire system. Stuck in both camps is the AMG GLC 63. In some ways it bridges the gap between the Jeep/Range Rover camp and that of the Porsche/Alfa, offering up a V-8 for the former crowd and the European sensibilities of the latter. It didnt take long to feel confident behind the wheel of the AMG, Erick said. True to its new AMG badge, the GLC 63 begs to be pushed to its limit. Trouble is, you might not like what you find once you get there. Steering just feels good: sharp, precise, perfectly weighted, Jonny said. But once you start pushing the GLC 63 S Coupe, the damping lets the car down, and it starts to bounce around on its air springs. Even in its firmest mode, the AMGs suspension never proved to be stiff enough to deliver the high-gain experience that the rest of the GLC package was promising. Exhausted after a long day on Angeles Crest, we fueled up and cannonballed to Las Vegas. Little green men were waiting. Warp Speed Ride and handling get a well-deserved portion of the attention during Best Drivers Car. But as you well know, its only half of the formula that makes a drivers car just that. Its the atom without the neutron, if you will. Our next stomping ground: a blazing-hot scenic drive along some of Americas most top-secret sites on the deserted Extraterrestrial Highway, skirting Area 51, across the barren U.S. Route 6, and then a straight shot down US-95, hugging the edges of the nuclear-weapons Nevada Test Site to reach our end point in Death Valley. Leaving Vegas by car is always a gamble, one I won by scoring the keys to the Alfa. For a knife-fighter, the Stelvio is remarkably comfortable on the highway. Its high-strung V-6 is brutally powerful; its laggy off the line, but once the turbos spool up, it sends out wave after wave of torque. The engine is powerful and the transmission doesnt need your guidance; its fine on its own, said Scott. The test data shows hes right. The Alfa accelerates from 0 to 60 mph in 3.5 seconds, and itll run the quarter mile in 12 seconds flat at 114.4 mph. Yet these startling numbers are only midpack in this group. The Macan futilely attempts to hang on the Alfas tail. Hustling through the San Gabriel Mountains the day before, the Macan felt quick. But out on the endless straights of Nevada highway, its power disadvantage becomes apparent. Its kind of amazing how much horsepower can skew things; the Macans 440 ponies are enough to get it from 0 to 60 mph in a properly quick 3.8 seconds and through the quarter mile in 12.5 seconds at 109.4 mph. But in this group that still makes it second slowest. The Range Rover Sport SVR brought up the rear of our strike packagenot that those driving it minded. Arguably the most comfortable long-haul cruiser of the bunch, the Rover had another trick up its sleeve. The award for best exhausts goes to the Range Rover Sport SVR, Erick said. But it sounds much quicker than it feels behind the wheel. Hes right. In nearly all of our instrumented tests, the SVR trailed this pack. It takes the Range Rover Sport 4.3 seconds to accelerate from 0 to 60 mph, and it needs 12.7 seconds to cross the quarter mile at 110.9 mph. Thats hardly slow, but it aint setting speed records in this crowd. Amazingly, our two fastest SUVs were designed for the same job but go about it in completely different ways. The Jeep is all about power. Its 707-hp V-8 allows Jeep to ignore the Grand Cherokees curb weight and focus instead on blistering straight-line speed. That suspension that left the Trackhawk flopping around Angeles Crest? Well, when launched, the Trackhawk hunkers down on its rear haunches as it claws down the tarmac. Your view changes from street to sky. All the SUVs in this group are quick, but oh my, the Trackhawk is something else completely, Collin said. From a stop. At low speeds. At highway speeds. You put your foot down, and it just takes off. It never gets old at least as long as youre going in a straight line. The better-balanced Mercedes doesnt need any more than the 503 horses under its hood thanks to its nearly 1,000-pound weight advantage. The AMGs big V-8 puts out all the cruel and lovely snarls were used to, deep and throaty and pretty much hinged, Jonny said. It feels both torquey and fast. The GLC 63 S loves eating up highway miles at extralegal speeds just as much as it does launching hard for drag races. In instrumented testing, the GLC 63 S and Grand Cherokee Trackhawk are constantly trading blows. The German and American tie each other from 0 to 30 mph, the Jeep edges the Mercedes to 40 mph, the Mercedes comes even at 50 mph, and then ultimately it takes the 060 crown. The GLCs 3.2-second 060 run ties the Tesla Model X P90D for the quickest SUV weve ever tested. The Merc is also the quickest gas-powered SUV weve ever run down the quarter miletying the Jeeps 11.7-second quarter-mile time but at a higher 116.5-mph trap speed. Its close enough to call it a draw. Even in the open desert, local police presence means this fight wont be settled today. Mission Accomplished I think its fair to say that everyone hated my logistical planning skills after our loop through Nevada to Death Valley. After a long day, the only alien we saw was the plaster one standing outside of the Alien Research Center in Hiko, Nevada. The only flying saucer we saw was hanging from a battered tow truck outside the Little ALeInn in Rachel, Nevada. As for under-the-radar military stuff, we did see an old Nike nuclear-tipped missile serving as a gate guard for the secretive Tonopah Test Range, and a 50s-era French fighter jetlikely belonging to the Air Force test pilot schoolbuzzed us. Im sure those were secret at one point or another. But despite the hassle, there was a reason we wound up in Death Valley. While the military develops its latest black projects in Area 51, not far away in Death Valley, the auto industry tests its own top-secret stuff. Bugatti Chirons and Ford GTs were both partially developed in the national park. Hell, we even bumped into Acura engineers hard at work on a to-be-announced performance MDX variant. Its a fair bet that each of our five super SUVs spent some development time in Death Valley, their test drivers, decked in bulbous helmets and the loose skin of racing suits, taking on a vaguely alien appearance as automotive engineers prod them for thoughts on how to push the performance envelop just a little bit past what we previously imagined possible. That evening, with beers to quench the deserts heat, our SUVs ticking in the cool desert night behind us, it was time to take all wed learned and pick the SUV that most deserved a shot at Best Drivers Car. After allonly the best-driving SUV stands a shot at knocking BDCs purebred sports and supercars off their pedestal. Were Best Drivers Car singularly focused on straight-line speed, the 2018 Jeep Grand Cherokee Trackhawk wouldve been a sure bet. Its stupid fun to bury the Trackhawks throttle in a straight line, but its severely underbraked for an object as fast and heavy as it is, and its handling performance is perhaps most kindly described as sharp as a hammer. Last place in this group is nothing to hang your head about, but this bruiser would be outgunned at Best Drivers Car. The 2018 Land Rover Range Rover Sport SVR finished ahead of the Jeep by a nose. Despite the Rover being the slowest SUV in this comparison, this isnt a numbers game. Simply put, out on the road, the Range Rover Sport is more enjoyable to hustle through a corner or two, making the most of its power. Although price wasnt a factor in this comparison, its worth mentioning that the SVR, especially its interior, felt worth every bit of its $28,500 premium over the next-cheapest SUV here. The 2017 Porsche Macan Turbo with the Performance package earned third. The Porsche does almost everything rightits quick, it goes around a corner well, and its easy to drive fast. So what went wrong? It commits the cardinal sin of being boring, Jonny said. Im sorry, but Porsches, by definition, cannot be boring. Collin agreed: Driving the Macan was kind of like watching Tom Brady play football. Hes an incredible quarterback, but guys like Cam Newton and Russell Wilson play a more exciting game. And that sets us up the battle for first place between the 2018 Alfa Romeo Stelvio Quadrifoglio and 2018 Mercedes-AMG GLC 63 S. The Alfa lives for slicing up your favorite back road, yet its equally satisfying at high straight-line speeds. This thing is phenomenal in a way that you have to experience to understand, Collin said. The Mercedes trades some of that sharpness in favor of a slightly more comfortable commute-friendly ride, and its also the fastest SUV weve ever tested, period. The experience reminds me of the GT R, Erick said. That the GLC 63 S evokes the same visceral and satisfying experience as AMGs halo car is a huge success. Ultimately its a game of inches, and with Best Drivers Car rules in place, the Alfa Romeo Stelvio Quadrifoglio earns the win. The Merc is quicker, but the Alfa is the most fun SUV here to drive, and in spite of its SUV-ness, its also one of the most outstanding vehicles on the roadregardless of shape, size, or curb weight. Like the secret projects being built in the middle of the Nevada desert, automotive enthusiasts might not like what the Stelvio Quadrifoglio represents. But theres no denying that Alfa accomplished its mission of building a drivers SUV. Best Drivers Car contenders, you have your work cut out for you. Godspeed. 5. 2018 Jeep Grand Cherokee Trackhawk The worlds fastest studio apartment is great in a straight line but leaves us wanting in corners. 4. 2018 Land Rover Range Rover Sport SVR Its guaranteed to score you a primo valet spot, if not necessarily a spot on the podium. 3. 2017 Porsche Macan Turbo (Performance Package) The soul weve come to expect from Porsche products is nowhere to be found. 2. 2018 Mercedes-AMG GLC 63 S 4Matic+ Coupe Say hello to the quickest SUV weve ever tested. Sort out its body control, and we might have had a different winner. 1. 2018 Alfa Romeo Stelvio Q4 Quadrifoglio Take everything you thought you knew about lumbering SUVs and throw it out the window.
