Production Ends on Old Grand Cherokee, But You Can Still Buy One New

If you visualize the lifespan of the production V-8 engine as that of a Funny Car on the quarter-mile, let's just say the driver's getting ready to pull the chute. That ticking you hear ain't your lifters; the lap timer's running down on the great eight, with the final V-8s likely thumping around under the hood of trucks and a forlorn contingent of muscle cars and rarified sports cars into the early 2030's. There will be holdouts after that, but increasingly stringent regulations will continue to push out big displacement in favor of a gently humming set of electric motors.It's written on the pitlane wall, folks. Ford announced its intentions to have 40-percent of its fleet electrified by 2030, while General Motors shoots to eliminate its portfolio of internal combustion entirely by 2035. Dodge's first battery electric car—known only as the goofily named Challenger eMuscle— allegedly arrives in 2024. Even if these automakers keep pumping out V-8-powered Mustangmaro GT-Hell500s for decades to come, the market will have geographically shrunk; California announced plans to ban sales of ICE vehicles by 2035, with similar bills in place in New York, Massachusetts, and the city of Seattle. We're not saying we're positive these proposals will come to pass, but the sentiment certainly isn't going away.Mercedes-Benz: A V-8 DynastyThat's just for the American stuff. It's worse for the overseas V-8 junkie; Jaguar Land Rover and Bentley are two V-8 purveyors among a growing number of automakers taking the all-electric pledge. As did Mercedes-Benz, with the German automaker announcing this past summer that every new vehicle architecture launched after 2025 will carry batteries only.This is quite the loss for the greater V-8 portfolio. By our count, the 2021 model year offered American buyers a stunning 24 distinct Mercedes vehicles with a V-8 under the front hood. Granted, the mass majority carry a variant of the same M176/177/178 4.0-liter twin-turbo V-8, but we'd rather not see that engine's prolific status culled to zilch in the coming decade.Bummer. Not only has Merc played in the V-8 game for 59 years as of 2022, but the iconic German marque is responsible for some of the greatest eight-cylinder engines in history. The 6.3-liter M100 was Merc's first, roaring to life in 1963 under the hood of Der Große Mercedes 600, serving as Europe's first post-war production V-8 following the three-pointed star's rich history of inline-eights.The M100 proved hearty and hale enough to last through 1981, replaced in-step by the pre-existing M116 and M117 V-8s that ranged from a tiny 3.5-liters up to a full 5.6-liters. Before it was snuffed, the M100 stunned the world in 6.8-liter guise, shuttling dignitaries, bankers, and celebrities in the mighty 450SEL 6.9.Development and production of the Mercedes V-8 continued unabated through the 1980s and 1990s, a flowering family tree sprouting gas-guzzlin' greats like the supercharged 5.4-liter M113 V-8 found in AMG's early-to-mid 2000s "55" series. 2006 saw the introduction of the 6.2-liter M156, AMG's first fully in-house V-8 that kicked off the incredible "63" series of AMG-ified Mercs from its debut year through 2015.Flat-Out Into Flat-PlaneMercedes gradually phased out the M113 in favor of a blend between the twin-turbo 4.7-liter M278 and the AMG-facing twin-turbo 5.5-liter M157 in the early-to-mid 2010s. Then, the new 4.0-liter twin-turbo M176/M177/M178 family streamlined it all under the roof of a singular engine family; by 2020, every V-8 Mercedes carried some variant of the four-point-oh. In most cases, output differences boiled down to programming, turbo size and configuration, and intake/exhaust; depending on what the alphanumeric scrawl read on the rear decklid, power ranges from 456 hp to a wicked 720 hp. Jumping to the Mercedes-AMG GT's M178 adds beefy hardware to handle extended thrash sessions, notably swapping wet sump for dry sump lubrication, though most of the exploding stuff under the cowl of an AMG GT is recognizable when parked next to a C 63, or even S 560—with one notable exception.Enter the M178 LS2. In direct contrast to every production Mercedes V-8 ever—yes, ever ever—the AMG GT Black Series' 4.0-liter packs a flat-plane crankshaft in place of the garden variety crossplane spinny stick. Fresh camshafts and exhaust manifolds are snapped on to make sure everything plays nice with the exotic firing order, while turbochargers are upsized for an extra 5.0 psi of boost over the crossplane AMG GT R.Black Series is Code for Badass(er)Even amongst the rarified roster of atomic Black Series (BS) weapons, the GT BS oozes brutality. The body of the GT BS swells with menace and bristles with an arsenal of wings, canards, diffusers, vents, and slats that wouldn't look out of place on the Sebring starting line. You can rarely accuse Mercedes-Benz of goofing off on the job, but the GT Black Series is so serious, so singularly focused in its task of trackday subjugation, we wouldn't be surprised to learn the development engineers slept on the shop floor, munched on coffee grounds for breakfast, and only got to work after a three-hour morning MMA training routine. Aside from the leather and Alcantara swaddling the interior, the GT BS feels like a performance car commissioned by SEAL Team Six.Much like enemies Ferrari or McLaren's boosted flat-plane screamers, the bulk of the Black Series' 720 hp and 590 lb-ft arrives fashionably late in the rev-range, with all 720 braying racehorses peaking at 6,700 rpm, just 300 rpm short of redline. That thick shmear of torque fills in the gaps, the full 590 lb-ft coming into effect between 2,000 and 6,000 rpm.The result is a V-8 soundtrack and character unlike any other Merc thumper we've ever experienced. Power is predictably ferocious, but you wouldn't necessarily know that from the outside—or inside, for those hard of hearing. In fact, be careful where you flex with your new third-million-dollar track toy, lest you're aurally shown-up by the slower, less expensive, less exclusive, and surprisingly louder AMG GT R with its trademark AMG snap, crackle, and roar.The M178 LS2 sounds like a McLaren yelling from a padded asylum cell, with the best banshee notes scrubbed into sterilized, no-nonsense whap-whaps when you jab the throttle. Europe's stringent sound regulations no-doubt play a role in the odd hush, but you'd think a 720-hp hand-built AMG flat-plane V-8 would be challenging to render street-legal, let alone tolerable to stand adjacent to while idling. Still, it's a tremendous engine, and the perfect honed titanium hand grenade to sit at the top of Merc's gas-burning weaponry cache until made obsolete by a watermelon-sized electric motor.The Future of the V-8 is SaltyIf you're less of a brand tribalist and more of a general enthusiast of the great and mighty V-8, there is a safe haven from all the plug-in and shush-up on the horizon—you've just gotta be willing to get a little wet from time to time. For the foreseeable future, gas-burnin' boats and the marinized V-8 have solid sea-legs even as the landlubbers turn zappy, and that's not something at risk of changing overnight.While the bloodlines of the automotive V-8 sprouted out like a river delta, with each iteration expressing unique character and range of application, the marinized V-8 is less about personality than it is pure, uncut power. Don't expect your flotilla of V-8 cigarette boats to return the same experiential variance of a Ferrari V-8 against Chevrolet's finest smallblock, but hey—it's nice to know the V-8 thunder will still peal long after the echoes fade on shore.We came to this realization lounging on a dock down in the Florida Keys, specifically as we watched the latest collaboration between Cigarette Racing and Mercedes-AMG gently bob in the quiet marina. The orange-and-black 41-foot Nighthawk Black Series is the 13th AMG-branded boat to emerge from this partnership, and only the latest in a long dynasty of tremendously potent showcase powerboats from Cigarette Racing.Big names, big power. This waterbound AMG-branded speed-shard packs a cluster of five supercharged outboard V-8s rated for a combined 2,250 hp. Yeah, and you thought you were hot stuff with your C 63. The power-mad waterdogs over at Mercury Racing supply this firepower; an obvious matchup, as Mercury Racing is the biggest name for powertrains in the performance watercraft industry, and a subsidiary of one of the most storied and powerful marine-focused manufacturers in the world.It's fortuitous—and obvious— that Mercedes-AMG and Cigarette Racing would choose Florida as the debut stage for this latest mashup. Boats, big-blocks, and off-shore racing courses through the Sunshine State's sky-blue veins; Cigarette calls Opa-Locka home, while Wisconsin-based Mercury Marine holds deep, deep roots in the peninsula's waters—and not just the salty stuff.An Eight-Cylinder MeccaA short drive southeast of Orlando, a 1,440-acre enclosed lake laps placidly against its heavily wooded shores. On Google Maps, it's billed as Lake Conlin, just one of 50 named lakes in the county, but to the powerboat faithful, it's known by the outlandishly enigmatic moniker of Lake X.In 1957, Mercury founder Carl Kiekhaefer buzzed central Florida in a single-engine prop-plane, scouring the topography for a private lake on which he could conduct secret watercraft testing during the winter season away from the eyes of competitors and ears of annoyed neighbors. The 10,000-and-change acre property containing Lake X was soon purchased, and testing got underway immediately.Lake X soon became known as the off-limits mecca of powerboat development, with rumors growing into legend; up until the early 2000s, if it was fast, if it was loud, and if it was powered by Mercury Racing, it was fine-tuned at Lake X. Regardless if you prefer your feet wet or dry, this unassuming Floridian lake is a holy site in the bible of the V-8. We had to pay our respects.This roadtrip from Miami to Lake X was, in a sense, our decade-early epitaph for Benz's V-8. Our funeral procession was tiny, but meaningful; Mercedes opened the archives and tossed us the keys a 2008 CLK 63 AMG Black Series, one of the most characteristically V-8 AMGs to ever spin a tire in anger. If the flat-plane M178 LS2 is the cutting-edge, sci-fi warp-drive zenith for the Merc V-8, the CLK's 6.2-liter M156 is the heart of an old warship pulled straight from the industrial era.Obviously Old-SchoolIt's got all the mechanical hallmarks of a modern engine—dual-overhead cams, four-valves per cylinder—but out on the arrow-straight backroads lancing through central Florida, it feels like something plucked from the streets of Byzantium. In direct contrast to the clean, crisp guttural blats issued from the current crop of 4.0-liter M178 V-8s, the rear of the Mars Red coupe clattered with dirty, oily thunder. The sound is paleolithic, almost inappropriate; if a medieval peasant heard this metal-on-metal crackle emitting from the bowels of a bone-strewn cave, a raiding party would be assembled.500 hp and 465 lb-ft means it certainly has the hustle to match the roiling heavy metal soundtrack, though progress has sapped our serotonin receptors; hampered by a slow-ish shifting seven-speed automatic transmission, the CLK 63 Black Series offers about as much forward poke as a 2022 Ford Mustang GT; less, actually, as an automatic 'Stang undercuts the CLK by 0.6-seconds in the quarter-mile.But in its prime? What an athlete. In 2008, 500 hp was enough to step on the necks of the contemporaneous BMW M3, poke the eyes of the 911 Turbo, kick sand in Aston Martin's martini, and grab at the heels of the C6 Corvette Z06. The noises make you blush, but the power delivery makes you swoon; power is relatively peaky, encouraging a heavy right foot and deep, deep drinks from that wellspring of torque.Orlando-Based Bond VillainyThe chainlink gate to the Lake X facility arrived in a rush. After rumbling down a tree-lined path, a place-out-of-time greeted us; a back parking lot gives way to a cracked and uneven stretch of concrete that extends from the main structure to the water's edge. The first thing constructed at the testing facility was a channel of concrete sea-walls, sluicing straight into a covered engineering workshop built in 1969 that has the space to house a small marina's worth of boats. There's a distinct spy-thriller vibe to the complex, with large plexiglass dome portals ringing the primary building and peppering the exterior of the disused but oh-so-neat observation tower.For a site so integral to the history of the loud-and-brash marine V-8, Lake X sure is tranquil. Mercury used the lake for testing until the early 2000s, when boats were just too fast for the lake's size. "180 mph shrinks any size," laughed Ken Eckert, facilities manager and engineer. After Kiekhaefer sold the property to entrepreneur Kenneth Kirchman in 1984, the new owner established a foundation dedicated to using the lush grounds and wetlands of Lake X to educate the public on Florida's ecology and wildlife.Mercury returned in 2017, using the historic grounds as a satellite engineering and testing shop. "We can do stuff here in a day that would take five days to do on a public waterway," explained Eckert. "No wake zones, no other boaters, and no one to get in our way."It's a small, wild capsule of serenity teeming with life. As we staged photos of the bright red CLK, a flock of wild turkeys strutted through the adjacent field. A gator floated lazily by one of the seawalls, while a heron waded a few yards down the shore. Inside the workshop, an engineer stripped down a 600-hp V-12 outboard for inspection.V-8 Boats Forever? Maybe, Maybe NotMuch like an empty race track, Lake X was eerily quiet without the one-note roar of a powerboat. Luckily, I was just there on a quiet day; chatting with the folks at Cigarette Racing and Mercury Marine instilled in me the belief that the marine V-8 has a long, long life ahead of it—but not without change.There's far less regulations and oversight levied onto marine engines, and depending on the engine, most units are uncatalyzed. "Is there potential for stricter regulations going forward? Most definitely," said Eckert. "That's certainly on our radar, and as everything we do, we look to the future. If the regulations change, I am 100-percent confident we could seamlessly change with them."As of right now, widespread adoption and development of purely electric boats is unlikely, due to the aforementioned lack of legislative pressure, a nonexistent charging infrastructure, and the dramatic inefficiency of electric marine drivetrains relative to the electric car.  Still, there are moves being made behind the scenes. Mercury Marine's parent company—the Brunswick Corporation—just acquired a battery company last September "to extend its leadership position in electrical systems innovation," the company said in a release. As of right now, this expansion might just be for small-scale lithium-ion battery systems for auxiliary power, but this seems like a logical first step toward serious electrification.So, no speedy-but-silent powerboats for now. But in the future? "I think you'll see electric outboards in smaller vessels to start with, and you know how it goes—you've got to start developing the technology to make strides," Eckert mused. "I'm confident that over the years, it won't be an uncommon thing to see an electric powerboat." Then, the V-8 might truly begin its final decline. Maybe.If that dreary dystopia ever arrives, perhaps we'll pull one of Cigarette Racing's AMG collaborations out of storage and go for one final blast. We know just the lake for the occasion.

Whereas there's plenty of hubbub around the V-8-equipped $80,000 Jeep Wrangler 392 and how Jeep finally has stiff competition in the Ford Bronco, there's much less chatter surrounding the other Wranglers. The bulk of the auto market may gravitate toward decked-out variants, but there's still a place for base trims. You know, the ones that cost $30,000 and form the foundation upon which the upper-echelon trims are built. There are still stubborn Jeep guys who just want a Wrangler—just not a Wrangler weighed down with every option. Luckily, Jeep provideth.Consider this: You can theoretically buy—good luck finding one in real life, though—a brand-new two-door 2022 Jeep Wrangler Sport for $29,995 that comes standard with Uconnect 3 with an itty-bitty 5.0-inch touchscreen display and no air conditioning. Even the next trim, Willys Sport, can be had with no air conditioning. (We actually know a guy who opted for a brand-new Wrangler devoid of A/C. Absolute hero! Or just young and broke.) Luckily, you can choose to be frosty. There is the option to upgrade to Uconnect 4 with a respectable 7.0-inch touchscreen. This $1,395 option on the configurator also gets you air conditioning.Fast-forward to model year 2023, and Jeep has implemented some changes to its bare-bones, base-trim, two-door 2023 Jeep Wrangler Sport—while only raising the MSRP by $300 to $30,295. For better or worse, it's still base, but a little less base. Uconnect 4 with the 7.0-inch touchscreen is standard, and Uconnect 3 with the 5.0-inch touchscreen officially dies. That means standard air conditioning; all Wranglers great and small have standard air conditioning for 2023. For those who hate the idea of A/C, crank down that manual window and leave the A/C off. Don't panic—2023 Wrangler Sports retain standard manual door locks, manual windows, and a manual transmission behind the 3.6-liter V-6. Luckily, even the 2023 Wrangler Sport still gets the Smoker's Group option, complete with a removable ash tray and a cigar lighter.Although the two-door 2022 Wrangler Sport still comes standard with the smaller screen and no A/C, that's not the case with the four-door Unlimited configuration of the same year; it made the switch to the better Uconnect, screen, and A/C for 2022. Bottom line: Doors matter.More broadly, the 2023 Jeep Wrangler drops three trims (Sport Altitude, Sahara Altitude, and High Tide) and a few colors (Snazberry and Gobi)—but there's plenty of time for Jeep to garnish its 2023 fleet with more new trims and colors. Pricing remains pretty stable, with the four-door Sahara seeing the biggest jump at $2,170, and some trims (four-door examples: Willys Sport, Sport S, and Rubicon) actually becoming less expensive.These changes in standard equipment for the 2023 Jeep Wrangler Sport two-door help it fall more in line with the Base Ford Bronco, which has air conditioning and Sync 4 with an 8.0-inch touchscreen. But still, RIP Wranglers without A/C. You'll always be hot.

bmw m5 Full OverviewThe new 2022 BMW M5 CS (short for Competition Sport) is not only the most outrageous version of the F90 (sixth generation) M5, but also one of the most ridiculous production BMWs of all time. It's certainly the most powerful: The S63 M TwinPower twin-turbo 4.4-liter V-8 makes 627 hp at 6,000 rpm and 553 lb-ft of torque between 1,800-5,950 rpm. The peak-torque figure is the same as you find in the M5 Competition, but it's available in the M5 CS for an additional 90 rpm. That might not seem like much, but keep in mind the M5 Comp's peak-torque rpm-range already exceeds the standard M5's by 170 rpm. In terms of M5-vs.-M5-vs.-M5 horsepower comparisons, the M5 Competition makes 617 horsepower at 6,000 rpm, and the standard M5 600 hp.The 2022 BMW M5 CS gets more than just additional power and revs compared to its "lesser" versions. It features the same chassis and suspension upgrades the M5 Comp boasts over the M5—stiffer engine mounts and suspension springs, 0.2-inch lower ride height, more negative front camber, and a stiffer rear anti-roll bar and toe-link ball-joint mounts. BMW says the M5 CS receives additional "spring and Dynamic Damper Control tuning" compared to the M5 Competition "to take advantage of the lower vehicle weight and of the optionally available (no-cost) Pirelli P Zero Corsa ultra-high-performance tires." Take note of the point about the rubber, as we'll circle back to it shortly.Ah, speaking of weight, the M5 CS tipped our scales at 4,089 pounds, whereas BMW says the M5 Comp checks in at 4,344 pounds. We have not had the opportunity to weigh an M5 Comp but suspect it would check in lighter than its official weight, due to the parameters under which BMW estimates its cars' curb weights. Either way, this is a notable difference between the two models, and the M5 CS' diet consists of additional carbon-fiber-reinforced plastic pieces, including the hood with vents in unpainted carbon fiber, the front splitter, mirror caps, rear diffuser, and rear spoiler. The engine cover is also made from CFRP, and further weight reduction comes thanks to less sound-deadening throughout the car.So, what do these upgrades yield in performance terms? We ran the 2022 BMW M5 CS through our standard battery of MotorTrend tests, with impressive outcomes.Gas ItIn our acceleration testing, the 2022 BMW M5 CS produced its best launches via its launch-control mode. This produced consistent, clean, and smooth yet explosive launches, and we noted how well the car put the power down without drama. Indeed, it exhibited zero, or almost zero, wheelslip; the AWD just dug in and blasted the car down the track. Our best 0-to-60-mph time came in at a double-take—hell, triple-take—inducing 2.6 seconds. That's the fifth-quickest time we've ever recorded to 60 mph, behind cars like the Tesla Model S Plaid, Ferrari SF90 Stradale Assetto Fiorano, Porsche Taycan Turbo S, Porsche 911 Turbo S, McLaren 720S, Lamborghini Aventador SVJ, and Audi R8 V10 Plus, to name a handful. It also means the CS is even quicker than BMW claims: The company says this M5 reaches 62 mph in 2.9 seconds, so even if we knock off 0.2-second to estimate a 60-mph time of 2.7, our 2.6-second time remains ahead.The BMW's performance through the quarter mile was no less stunning, with a time of 10.7 seconds at 129.7 mph. Only eleven MT-measured quarter-mile elapsed times have been quicker: the same cars mentioned above (and a bunch more). If you're employed as a wheelman by nefarious characters who appreciate the quickest of getaways, look no further; if Hollywood remade John Frankenheimer's 1998 cult-classic Ronin today, we know which new production car should feature in it.Slow Your RollDespite BMW's boast about the M5 CS' reduced poundage, the fact remains that a car of this size and a two-ton curb weight needs to stop as well as it goes. No problem there, as the standard carbon-ceramic brakes brought the M5 CS to a halt from 60 mph in just 101 feet, beating Cadillac's CT5-V Blackwing by 1 foot and trailing the Porsche 718 Boxster GTS 4.0—which weighs 916 pounds less—by only 2 feet. The brake-pedal feel was firm and consistent, and we felt good bite from the 20-inch Michelin PS4S tires. Our only knock against the overall setup is that the firm pedal's short-release travel makes it difficult to trail brake precisely into corners.DynamicsAh, did we just mention tires? As impressive as the 2022 BMW M5 CS performed on the Michelins, it really wants to live on its available, more aggressive, and stickier Pirelli P Zero Corsas. When we say, "available," we mean theoretically offered by BMW, but that's where things went slightly sideways for our test. (You can get the car smokingly sideways easily, too, for the record.) Unfortunately, supply-chain shortages affecting all walks of industry have hit the tire business as well, and despite our best efforts we were unable to source a set of the Italian rubber. Not only would it have almost certainly provided an even shorter stopping distance in our braking test, but it also would have improved the CS' performance on the skidpad and around our figure-eight course.Nevertheless, the big sedan pulled an average of 1.04 g on the skidpad, and it recorded a best figure-eight lap time of 23.2 seconds at 0.92 g average. The skidpad number equaled that of the CT5-V Blackwing, and the BMW bettered the Cadillac around the figure eight by 0.2 second and 0.03 g.These are all solid numbers, and we achieved them despite the M5 CS exhibiting loads of understeer on the skidpad and quite a lot of oversteer when exiting corners around the figure eight. Indeed, it was easy to see the M5 CS simply could not reach its full potential on these tires, which was a shame.Yes, You Want OneDespite being unable to record the absolute best test results, we saw more than enough from the 2022 BMW M5 CS to tell us the mechanicals are there. The engine is brilliant, the outright speed is breathtaking, and the brakes are good. The steering in its sportiest setting is quite nice, too; it loaded and unloaded clearly on the skidpad, which told us precisely when the front tires gained or lost grip. This is a proper driver's car, and then some, and it's the most capable BMW M5 of all time, by far. For all these reasons, we're still cursing the damned supply chain.On second thought, perhaps we're looking at this all wrong: We now have a legitimate excuse to get our greedy hands back on the 2022 BMW M5 CS when the better shoes become available—and we'll be thrilled to run it to its mega limits all over again, with even more impressive performance.Looks good!
