GM recalling 686k Lambda-platform models for hatch repair

General Motors is recalling 686,287 units of its Lambda platform crossovers. On models equipped with a power rear hatch the system can potentially fail. This campaign includes the 2008-2012 Buick Enclave, 2009-2012 Chevrolet Traverse, 2007-2012 GMC Acadia, and 2007-2010 Saturn Outlook. According to GM's documents to the National Highway Traffic Safety Administration (as a PDF), dirt can get into a portion of the strut that holds up the hatch and cause the part to prematurely fail. There's a redundancy in place called the Prop Rod Recovery system that's designed to shut the liftgate if there's a malfunction. However, if the breakdown happens too quickly after the hatch is opened the prop rod might not work the way it's supposed to. If someone were in the way of the falling liftgate, they could be hurt. For the repair, dealers will update the software for the power liftgate actuator motor control unit to prevent the hatch from closing so quickly. They'll also check the operation of the system afterward.

The affected vehicles, equipped with the power liftgate option, have gas struts that hold the power liftgate up when open. These struts may prematurely wear and the open liftgate may suddenly fall. CONSEQUENCE: If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury. REMEDY: GM will notify owners, and dealers will update the software for the power liftgate actuator motor control unit so that the motor will prevent the rapid closing of the lift gate, free of charge. The manufacturer has not yet provided a notification schedule.

Best Convertibles for 2022

The past decade has not been kind to the drop-top enthusiast. No matter which dealer you walk into, convertible models have been biting the dust left and right. Nissan Z? Audi TT? Buick Cascada? Volkswagen Eos? All gone. Remember the humble Chrysler Sebring/200? Well, you do now. Fortunately, though, the news isn't all bad. There are still plenty of options out there for those who absolutely must have a convertible. Whether you need something to haul behind your retirement cruiser, a performance car that can go toe-to-toe with the best in the world or just something that allows you to sling the roof back after a long day of on-location business meetings before catching the flight back to your everyday hustle and bustle, there's at least one cabriolet out there to suit your needs. Here are our picks and starting prices for the top convertibles in several categories for 2022.  For the frugal open-top lover: 2022 Mini Convertible ($34,650) Let's face it; gas ain't cheap. But open-top motoring doesn't need to be a wallet killer. The Mini is cheap (at least by 2022 standards) and an absolute joy to drive, so there's really no downside here ... except for the roof. Get it?    For the hardtop lover: 2022 Mazda MX-5 RF ($37,260) / 2022 Chevrolet Corvette Convertible ($69,695) The number of hardtop convertibles has seriously dwindled due to weight concerns and the fact that fabric roofs have gotten so quiet, but there are still some options for those who prefer a more coupe-like look with the roof up. Our picks here are the delightfully Targa-like MX-5 Miata RF and literally any Corvette Stingray — even the hardtop has a removable roof!    For long road trips: 2022 Ford Mustang Convertible ($34,100) The first image that comes to mind for many who are told to visualize an American convertible is the classic Ford Mustang. It's not the only drop-top pony car out there, but thanks to the Camaro's tiny trunk, it's much harder to see the USA in a Chevrolet when a drop-top enters the equation. The Mustang has much more cargo space and a much larger opening, which is likely the difference between keeping your bags under lock and key or leaving them exposed in the back seat.    For towing behind an RV: 2022 Jeep Wrangler ($31,590) While many small runabouts make sense for towing behind a motor home (or nestled up inside a fancier one), the Wrangler has a serious advantage when it comes to RVing: it can easily be flat-towed.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.
