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.

Editors' Picks August 2021 | Honda Civic, Mercedes S-Class and more

This month of Editors' Picks saw us award the honor to a couple of redesigned stalwarts like the Honda Civic and Mercedes-Benz S-Class. Plus, a new crossover that splits the difference between the compact and subcompact class takes home the prize. On top of this, we'll introduce you to a new term: midcompact. We'll be using this to describe those in-between crossovers that are a tad too small to be considered compact, but too large to neatly fit into the subcompact class. For a few examples of these "midcompact" cars, we'll point you to the Ford Bronco Sport, Kia Seltos and VW Seltos. In case you missed our previous Editors' Picks posts, here’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in August that earned an EditorsÂ’ Pick. 2021 Genesis G70 2022 Genesis G70 View 26 Photos Quick take: Genesis hits all the right buttons with its G70. It's attractive, fun to drive and can be had for a fair price. Enthusiasts should give it a shot before taking home one of its German competitors. Score: 8 What it competes with: Alfa Romeo Giulia, Lexus IS, Acura TLX, Infiniti Q50, Audi A4, BMW 3 Series, Mercedes-Benz C-Class, Cadillac CT4, Volvo S60 Pros: Sharp handler, stunning exterior looks, strong engines Cons: Average interior, loses manual option, small backseat and trunk From the editors: News Editor Joel Stocksdale — "I was already a big fan of the Genesis G70. It has brilliant handling, and the twin-turbo V6 is a beast. It's even a bargain against the competition. And Genesis just made it look a lot better. I wish they'd done a bit more to update the interior, but it's still not a bad cabin. Besides, you won't think too much about it when you're hustling down a fun back road." Features Editor James Riswick — "Yes, it is small, but in a sport sedan segment where "sport" means increasingly less, the G70 still delivers (in part because of that smallness).

2014 Chevrolet Corvette C7 Convertible offers a few more views before reveal

Over the weekend, Chevrolet released its first images of the new 2014 Corvette Stingray Convertible. Now, ahead of the droptop's official introduction tomorrow at the Geneva Motor Show, the automaker has given us a few more shots of the softop C7 showing off the car's rump albeit from a high, strategically positioned angle.
From this angle, it's hard to get a sense for how long and flat the decklid really is, but we can easily see that, like the rest of the C7's design, the new convertible's decklid and tonneau cover are far more detailed than the current car. We also get a better look at the rear haunches sans brake vents, which have apparently been moved to underneath the car in order to accommodate the top's hard cover.
As for the overall styling of the C7 convertible, with the top erected, we get some idea of what a coupe design (as opposed to the Stingray's fastback shape) would look like on this car. The C5 Corvette most recently had a coupe model that did away with the large glass hatchback, and we recently reported on a low-cost "coupe" model potentially being added to the C7's repertoire.
