Hankook Debuts Tweel-Like Airless I-Flex Tire
Ever since Michelin revealed the Tweel airless tire in 2004, it has been on the radar for anyone looking to reduce the need for monitoring tire pressures for optimum fuel efficiency and tire safety—at least for applications like ride-on lawnmowers and ATVs. Looks like Hankook is the next to get in on the act with its i-Flex concept that debuted on the Hyundai Plug-n-Drive module concept at CES 2022.
What Makes The i-Flex Different?
Compared to Michelin X Tweel, the Hankook i-Flex is far more organic in its design—and that's by design. The tire's structure was inspired by "the cellular structure of living organisms." According to Hankook, this allows for "better shock absorption while allowing hexagonal and tetragonal cell structures of different rigidity join together for more stable load support."
Made For An Autonomous Table
For now, the tire design is just a concept limited to a 10-inch outer diameter, which was perfect for the Hyundai Plug-n-Drive (PnD) module that also debuted at CES. You can almost think of it as a rolling, self-driven table. "The PnD modular platform is an all-in-one mobility solution that combines intelligent steering, braking, in-wheel electric drive and suspension hardware. The single wheel unit uses a steering actuator for infinite wheel rotation." In other words, it can turn around itself like that Lazy Susan on your table—except it's the whole table and it can drive around. With LiDAR and camera sensors, a PnD-enabled object can move autonomously, and the PnD modules can be attached to virtually anything that needs additional mobility.
When's It Coming?
The i-Flex has been in the works from Hankook since 2010, but a production version still isn't in sight. There are no explicit plans for building something larger than these small concept tires, but we have to imagine that Hankook is considering scaling up the concept for cars. We just don't know how far in the future that'll be.

ford f-150 Full OverviewIn announcing our MotorTrend 2022 Truck of the Year, we observed that today's trucks are far more than workhorses. They're also commuter cars, family haulers, weekend toys, and luxury vehicles. It's a trend at least 20 years in the making, but one that doesn't make everyone happy. Indeed, some of you wrote to us and expressed your displeasure with this mission drift and argued for trucks to be treated like trucks again. That's easier said than done, as it turns out. Take, for example, this 2021 Ford F-150 XLT Supercrew 4X4 we just tested.This isn't a blinged-out luxury truck; it's an XLT with cloth seats, a column shifter, basic four-wheel drive, a bedliner, and a max-towing package. One step above the base model, this should be a work truck, yet it's priced at $59,520 as tested. How the heck did that happen?What's an XLT, Anyway?A 2022 Ford F-150 XLT trim starts at a more reasonable $39,825 (banish the thought of a full-size truck starting for less than $30,000; those days are gone), but that only gets you a single cab, the base engine, and rear-wheel drive. Single cabs are old school, and every truck maker in the industry will tell you full four-door cabs like this F-150 Supercrew are bestsellers. That's an extra $5,260 right there.Four-wheel drive is a $3,425 upgrade, and getting a stouter engine adds at least $1,195. If you want to tow and haul heavy things on the job site or at the farm, you need power. This 3.5-liter twin-turbo EcoBoost V-6 has plenty of both, but it costs $2,595. After destination and acquisition fees, you're already nearing $50,000 without any other options.The rest of the asking price is made up of both the necessary and the nice to have. The max-trailer-towing package is $1,995, and the spray-in bedliner is another $595. Pro Power Onboard 2.0 kW, handy on the jobsite and in the field, is $995. Now we're at $54,000 for a work truck. The other $8,000 covers stuff you don't need for work but is nice to have, like the big infotainment system, optional wheels, etc.TowingYep, modern work trucks are expensive. The good news is you still get a lot of work for your money. We hitched this Ford F-150 XLT up to a high-profile two-horse trailer and found it to be the comfortable, stable towing platform we've come to expect from Ford. After returning the livestock, we filled the bed with a yard of hot, fresh mulch for the garden. Here again, the torquey twin-turbo V-6 made light work of the added weight, and the sizable payload and tongue-weight ratings meant the truck barely squatted.A Pleasant RideMore impressive, though, is how well the Ford F-150 XLT rides, either empty or loaded. With leaf springs capable of holding up 2,100 pounds of payload, you'd reasonably expect a stiff ride, but Ford's engineers worked wonders. The F-150 is as pleasant and comfortable to drive while doing work as it is cruising into town for groceries.Track TestingIt'll get you down to the market quick, too. Unburdened, the 3.5-liter twin-turbo V-6 hustled this 5,345-pound truck up to 60 mph in just 5.3 seconds and past the quarter-mile mark in 13.9 seconds at 99.9 mph.Power is not a problem, and neither is stopping. The Ford F-150 XLT was consistent in our braking tests from 60 mph, achieving a best result of 126 feet, about average for a full-size pickup. Even better, the stops were drama-free, with little nosedive or wiggling around.Handling tests were similarly uneventful. We discovered excellent composure for a pickup truck, with well-controlled body motions, good brakes, and strong traction. The 0.76-average lateral g it pulled on the skidpad and its 28.0-second figure-eight lap at 0.62-average g are on the right end of the full-size-truck class—and undersell how well the 2021 Ford F-150 XLT takes a corner without any weight loaded into it.SafetyOpt for Ford's $750 Co-Pilot360 Assist 2.0 suite of driver aids and included among all the safety stuff are adaptive cruise control and lane-keep assistance, which helps steer the vehicle and keep it in the center of the lane. Ford's system, which takes some load off your mind on long highway slogs, is one of the better hands-on systems on the market.Wrapping UpThe rest of the driving experience isn't bad, either. The cloth seats are plenty comfortable and feature a pleasing contrasting color scheme. The column shifter frees up a ton of center-console bin space and allows you to use the flip-out tray table while the truck is moving. The rear seat could use a bit more thigh support and recline, if we're being picky, but we like how much space it frees up when you fold it out of the way.As mentioned earlier, our truck was fitted with the big infotainment screen, and it's good to see how far Ford's Sync system has come. This latest incarnation is more user friendly and intuitive, sports modern graphics, and has a handy split-screen mode that lets you use Apple CarPlay or Android Auto simultaneously with other built-in programs like the radio without having to change screens.Simple fact is, unless you're a fleet manager buying dozens of trucks from a commercial dealer, even work trucks are pricey these days. Yes, the convenience and dress-up options can run up the bill, but even the stuff you need to get the job done will dent your budget hard. The good news is, these trucks drive, tow, and haul better than any time in history.Looks good!

Sequoia trees are thought to be the oldest living things on Earth, so it's appropriate that Toyota's full-size SUV is named for them: The soon-to-be-outgoing Sequoia dates from 2008, and over the three thousand years—okay, 13—it's been on sale, we've watched it slip from first to last in comparison to its competitors. Finally, it looks like a new Sequoia sapling is born: Toyota has revealed the 2023 Sequoia, with a few surprises that make it feel like an SUV for the ages.If you think the current Sequoia is a bit too plain—and certainly if you think it's too old—the new one should address your concerns. Up front, the new Sequoia shares its curves and creases with the all-new 2022 Tundra pickup truck. Out back, they've been re-interpreted a bit, with a fenderline crease that starts just ahead of the rear door handles and continues straight back to the taillights. It's less doughy and anonymous than the old model, more aggressive—traits backed up by what's under the hood.So, What's Under the Hood?For those keeping score in the Toyotaverse, the new Sequoia one-ups the (also Land Cruiser-based) Lexus LX600 in the power department. While both large SUVs share a 3.4-liter twin-turbo V-6, the Sequoia's is hybridized, assisted by an electric motor. With 437 hp and 583 lb-ft of torque, it thus bests the Lexus by 28 hp and 104 lb-ft. The hybridized six is an era away from the old Sequoia's 5.7-liter V-8, which made a paltry—by comparison—381 hp and 401 lb-ft. While we have yet to see official efficiency numbers, we can't imagine the Sequoia's hybrid powertrain won't improve on the LX's 19-mpg fuel economy; it's guaranteed to be better than the old Sequoia's mid-teens mpg.And doesn't that meaty hybrid sound like it has boat-towing power? Oh, you betcha. Toyota says the new Sequoia will tow up to 9,000 lbs, a 22% improvement over the outgoing Sequoia despite giving up two cylinders to its V-8. A Tow Tech Package, which (among other things) steers the trailer in reverse, helps alleviate some causes of towing apprehension.Don't Say Land Cruiser... Speaking of the Land Cruiser—which we swear we were just a minute ago—we found a possible explanation to the demise of Toyota's former flagship SUV (other than its relative lack of sales): The Sequoia will be available in a new range-topping Capstone trim, as recently announced for the Tundra pickup, pushing it into the old Land Cruiser's price turf. With 22-inch chrome wheels, two-tone black-and-white semi-aniline leather, and open-pore walnut wood distinguish this model from lesser Sequoias, which include Platinum, Limited and SR5 models.Another quick aside: The Sequoia shares its basic bones with the new Tundra, of course, but also with the newest Land Cruiser sold globally. While it is not a replacement for the iconic Land Cruiser 4x4, which is renowned for its off-road prowess, it is at least related to that SUV.To help fill in the void left in its lineup by the Land Cruiser and to build on the previous-generation Sequoia's off-road offerings, Toyota will once again offer a TRD Pro model, which includes Fox internal bypass shocks, a forward skid plate, multi-terrain drive modes, and Toyota's Crawl Control mode, which maintains a slow, steady speed uphill or down. You'll find plenty of TRD badging inside and out, and this version is only available with four-wheel drive.If the TRD Pro is too, uh, pro for you, SR5 and Limited 4x4 models can be had with a lighter-duty TRD Off-Road package with a locking rear differential, specially-tuned springs and Bilstein shocks, unique 18-inch wheels, as well as the terrain modes and Crawl Control from the TRD Pro package. SR5 models are also offered with an on-road-tuned TRD Sport package with 20-inch wheels, TRD-tuned springs and shocks, and aluminum pedals. Two-wheel drive is standard and part-time four-wheel drive is optional on all on SR5, Limited, Platinum, and—surprisingly—Capstone trim levels. The Sequoia once again utilizes a fully independent suspension, though since 2008 more competitors have added this feature in place of a more traditional (and pickup-truck-like) live rear axle, including the Chevy Tahoe and GMC Yukon.Safely In Modern TerritoryAs with other Toyota models, a full safety and driver-aid package is standard, including collision detection with automatic braking, adaptive cruise control, lane departure alert and correction, automatic high beams, a blind-spot monitor, rear cross-traffic alert, and parking assistance with automatic braking.Inside, the Sequoia is just as new and fresh-appearing. Also, like before, the dashboard and steering wheel are essentially carryover from the Tundra pickup. There is an available large (14-inch!) central touchscreen, chunky air vents, and an available digital gauge cluster. What's important here is that nothing looks like it was designed in 2007—a key step forward.Toyota will build the Sequoia at the same San Antonio, Texas, plant that assembles the Tundra. We'll have pricing and fuel economy data as we get closer to launch, which will come when the weather gets warm; Sequoias are scheduled to arrive at Toyota dealerships this summer. We're looking forward to seeing how this modernized old tree branches into the full-size SUV space, which is now chock full of relatively new contenders, including the recently redesigned Chevy Tahoe, GMC Yukon, Nissan Armada, and all-new Jeep Wagoneer.
Koenigsegg is celebrating 20 years of making the wildest (and most Scandinavian) supercars in the world with a hell of a birthday present to itself: the CC850, essentially a remaster of its first car, albeit with a wildly clever manual/automatic transmission. That first car would be the CC8S, which founder Christian von Koenigsegg spent nearly a decade creating, starting with a very rough prototype and progressing, finally, to the company's first production model. The road from there to here has been fast and wild—it's hard to believe it's been two decades, in fact, a testament to how fresh and how bold the company's cars were when new. Read on for a guided tour through the marque's 20-year history, a quick way to understand how Koenigsegg became the inventive outfit it is today.
