Here are the best-selling cars and trucks from January 2015

Every month, Autoblog slogs through all the sales figures reported by automakers that do business in the United States, and, after a little bit of sorting, we put it into an easy-to-read chart in an attempt to make it as easy as possible to follow the ins and outs of sales and shipments. But that only covers the brands themselves, not the individual models they sell. And we think you'd all be interested in knowing which vehicles beat their rivals in sales from month to month, so we've put together this handy gallery to keep you in the know. While the leader of the pack may not come as much of a surprise, the order that the top ten finishes in changes frequently – due to automaker deals, the price of gas, etc. – and we've included some statistics to help you see how their current performance stacks up to month's past.

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.

Mustang retakes monthly pony car sales crown from Camaro

Going back to their origins in the Swinging '60s, the Ford Mustang and Chevrolet Camaro have been fierce rivals for fans' hearts and dollars. Historically, the Ford often led in volume, but Chevy took the muscle car top spot in 2009 upon the Camaro's rebirth. However, with the launch of the latest Blue Oval pony car, the tide is turning back in Ford's favor. November was the first full month of sales for the new 2015 Mustang, and according to TheDetroitBureau.com, the model did spectacularly well. The Blue Oval shifted 8,728 of them, up 62 percent from same month last year, with the automaker proclaiming it the model's best November sales since 2006. Conversely, 4,385 units of the Camaro were delivered, down 13.5 percent year-over-year, meaning its sales were roughly half that of the new-generation Mustang. Ford is understandably happy with the results, and product development director Raj Nair even hinted to TDB that another version of the Mustang might be unveiled at January's North American International Auto Show. Rumor has it that the model will be the even more potent Shelby Mustang GT350R. Despite the Mustang's November success, the Camaro outsells it year to day. So far in 2014, Ford has sold 73,124 Mustangs versus 79,669 examples of the Camaro. With December offering the last chance for an overtake, the Bowtie may yet remain king for this year's sales crown. A new Camaro is peeking over the horizon, as well. It's reportedly moving to the Alpha platform used by the Cadillac ATS, and production could start in late 2015. Prototypes are already testing at the Nurburgring, and camouflaged examples have been spotted weirdly being compared to its '80s forefather.
