2020 GMC Sierra Review & Buying Guide | The same but different

For the most part, the 2020 GMC Sierra 1500 and the Chevy Silverado are very close siblings. And with the more modestly equipped Sierra SLE and SLT models, choosing between the equivalent Chevy and GMC largely comes down to styling preference and whether you got a better deal at the GMC dealer. They’re almost identical twins. Almost. Because despite the shared DNA, there are differences in terms of model choice. There's no GMC equivalent to the cheaper Custom Trail Boss, for instance, but there is the high-dollar off-road-oriented AT4 that goes beyond the Chevy LT Trail Boss with more equipment and the availability of GMC's unique MultiPro tailgate and CarbonPro carbon fiber bed. Those are also available on the GMC Sierra Denali, which further differs with an adaptive suspension not offered by Chevrolet that seriously improves the ride comfort and handling composure of GM's full-size trucks. GMC therefore makes a compelling case for itself if you're willing to spend more for your truck, but having said that, the range-topping Sierras also don't go above-and-beyond in the same ways as the ritzy Ram 1500 and Ford F-150 trim levels do to provide a proper luxury truck experience. The new Duramax diesel engine at least stands out, but otherwise the Sierra doesn't offer a lot that others can't match or better (even within the GM family). What's new for 2020? CarbonPro Editions debut for the AT4 and Denali trim levels. These include the CarbonPro composite bed and a Kicker audio system in the MultiPro tailgate. The AT4 versions also gets some unique exterior trim. Mechanically, a 10-speed automatic is now paired with the drivetrain combo of 5.3-liter V8, Dynamic Fuel Management and four-wheel drive. Aiding visibility are newly available trailer tow mirrors, a bed-view camera, and a high-def 360-degree camera system with trailering elements.  What's the interior and in-car technology like? Like its Silverado sibling, the Sierra's cabin is its least compelling and competitive attribute, falling far behind the Ram 1500 and Ford F-150 in terms of quality and design. The dash is drab and frankly ugly in every trim level, but the cabin is particularly damning in the Sierra Denali. Its black vinyl "stitched" onto the black dash and some token strips of wood trim slapped onto the center console and doors just aren't enough to create the sort of high-dollar ambience truck buyers can find elsewhere.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

Best car infotainment systems: From UConnect to MBUX, these are our favorites

Declaring one infotainment system the best over any other is an inherently subjective matter. You can look at quantitative testing for things like input response time and various screen load times, but ask a room full of people that have tried all car infotainment systems what their favorite is, and you’re likely to get a lot of different responses. For the most part, the various infotainment systems available all share a similar purpose. They aim to help the driver get where they're going with navigation, play their favorite tunes via all sorts of media playback options and allow folks to stay connected with others via phone connectivity. Of course, most go way beyond the basics these days and offer features like streaming services, in-car performance data and much more. Unique features are aplenty when you start diving through menus, but how they go about their most important tasks vary widely. Some of our editors prefer systems that are exclusively touch-based and chock full of boundary-pushing features. Others may prefer a back-to-basics non-touch system that is navigable via a scroll wheel. You can compare it to the phone operating system wars. Just like some prefer Android phones over iPhones, we all have our own opinions for what makes up the best infotainment interface. All that said, our combined experience tells us that a number of infotainment systems are at least better than the rest. WeÂ’ve narrowed it down to five total systems in their own subcategories that stand out to us. Read on below to see our picks, and feel free to make your own arguments in the comments. Best infotainment overall: UConnect 5, various Stellantis products Ram 1500 Uconnect Infotainment System Review If thereÂ’s one infotainment system that all of us agree is excellent, itÂ’s UConnect. It has numerous qualities that make it great, but above all else, UConnect is simple and straightforward to use. Ease of operation is one of the most (if not the single most) vital parts of any infotainment system interface. If youÂ’re expected to be able to tap away on a touchscreen while driving and still pay attention to the road, a complex infotainment system is going to remove your attention from the number one task at hand: driving. UConnect uses a simple interface that puts all of your key functions in a clearly-represented row on the bottom of the screen. Tap any of them, and it instantly pulls up that menu.
