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.

GM expected to debut two new crossovers at Detroit Auto Show

Next month, General Motors is expected to debut two new crossovers at the North American International Auto Show. That's according to Automotive News and The Wall Street Journal, which reports that the successors to the aging Chevrolet Traverse and GMC Terrain will finally make their debut. The two crossovers have been on sale since 2009 and 2010 respectively and are due for updates as the competition has newer models on the market. Both crossovers play in growing market segments where sales success is crucial for the respective brands. GM, and the automotive industry as a whole, has been shifting its focus towards crossovers in the last few years. The Traverse and the Terrain are some of the oldest SUVs on the market and are in dire need of an update. GMC's Acadia, the former corporate clone to the Traverse (and Buick Acadia), switched to a new platform in 2016. And the Terrain's platform-mate, the Chevrolet Equinox, was revealed a few months ago. Both the new Chevy and GMC models are expected to go on sale late in 2017 as 2018 models. Look for a follow up to the Traverse's sister, the Buick Enclave, to make an appearance soon.

Autoblog In Cuba: 1957 Chevy Bel Air Review

If you've been following the Autoblog In Cuba series, you may remember that my efforts to rent a car in the country were ultimately unsuccessful. Misinformation, bad planning, and a lack of rental car inventory conspired to disrupt my hoped-for driving adventure. I discovered in my week of exploration, however, that the terrific thing about Havana is that there's always another adventure to be found – if you're willing to look. A car I could drive myself might have been impossible to come by, but a ride to remember was not. After all, even when reviewing a new car, I've found that impressions about the car and the route can be credibly formed from the right seat. Starting from the parking lot of the grand Hotel Nacional, finding an interesting car for hire is as simple as walking up and down the block. Scads of classic American iron wait just outside the hotel gates, in a riot of colors and conditions befitting the tropical climate. Fords from the 1940s are plentiful – more sedans than coupes – and the glory days of General Motors are represented by enough Pontiacs and Cadillacs to fill a Bruce Springsteen B-sides album. But the Chevy Bel Air is the king of the road here, by some margin. View 30 Photos I settled on a burnt orange 1957 Chevy Bel Air convertible, in tourist-appropriate condition. I was looking for a hardtop at the request of my crew's audio/video needs, but settled on a burnt orange 1957 Chevy Bel Air convertible, in tourist-appropriate condition. This car might look good as a prop in the background on your vacation photos – hair blowing in the breeze with the ocean at your back, parked in front of Che's face in Revolution Square, etc. – but was far from pristine on a closer inspection. A perfect representative of the Cuban average. At least the price was right: $50 for two hours to make it 12 miles to Hemingway's house, and back. My driver was a kid named Daniel who looked to be about 20 years old. The Chevy doesn't belong to him, he co-drives it with the owner, but he was able to give me the basic mechanical rundown. The eight- or six-cylinder engine that Chevy shipped this convertible with was long gone. No surprise there, as nearly every American-made car I'd ridden in so far was powered by some belching Mercedes diesel. Despite it's clattering note, Daniel said the lump under the hood of the '57 drinks gas: a four-cylinder of Russian origins, pulled out of a GAZ Volga as best I can understand.
