Top horsepower-per-dollar cars in 2017

Bang for the buck. That quasi-scientific statistic is bandied about by motor heads everywhere from classrooms to barrooms, though the truth of the matter is that it's exceedingly complex to measure. A fair performance-per-dollar index would include something like cross-referencing MSRP (Manufacturers Suggested Retail Price) with point-to-point times on a track or driving route, which is obviously hard to do comprehensively. But, for the sheer joy of talking about cars and playing with a big spreadsheet, there's always the horsepower-per-dollar index, which is more straightforward, albeit hilariously flawed. There are vagaries even with this simple formula, of course: MSRP for vehicles can change at a moment's notice, to say nothing of the bottom-line shifting that happens with local deals or showroom negotiation. For this list we're running with the straight MSRP wherever possible, and as recently reported as we can get it. All the vehicles on this list are 2017 models, and all trims are reported where the lowest price and differing power levels intersect. Some choices were made for personal preference and some for sanity, avoiding things like all 48 trim levels of the Ford Transit, all with the same horsepower). If this list were a simple top ten, or even a top fifty, you'd be bored to tears with all the red, white and blue that is represented. Following perfectly with conventional wisdom, American cars really do lead the world where hp/$ is concerned. So, for the sake of variety (and the sheer joy of seeing a minivan 'win' one round of this thing) I've sorted out some top five and bottom five lists for broad power categories. Let's dive in. Less Than 100 Horsepower Okay, okay, this is hardly a category we'll grant you. But we've often tried to click off all the sub-100-hp cars on sale in the US, and making this list gave us an excuse. It also illustrates that none of these smallish vehicles bring cheap horsepower to the table - for that you'll need a motorcycle. The segment-leading Chevy Spark (above) asks just over $139 for each hp, and that Smart Fortwo Electric Drive has hp on sale for about the same price as its very distant family cousin, the Mercedes-Benz SL65 AMG (insert your favorite Smart joke here... we know you want to).

2022 GMC Sierra 1500 Denali gets Super Cruise and an upgraded interior

The 2022 GMC Sierra 1500 is getting Super Cruise! Exclamation point required, because this is exciting news. Cadillac has been the sole owner of Super Cruise at GM from the start, and though we knew it was coming to the Hummer EV, we didn't know a fast-selling full-size pickup would be getting the technology. GMC says it will launch Super Cruise on the 1500 Denali, which is the most expensive and luxurious trim of the Sierra. It’s scheduled to arrive for the 2022 model year, but GMC qualifies that by saying “late model year 2022.” That means itÂ’s probably coming right toward the end, with 2023 scheduled as the first full year of Super Cruise in the Sierra 1500. GM also claims that the version of Super Cruise coming to the Sierra is capable of towing. Yes, hands-free towing, folks. WeÂ’re a little antsy, too. The tech is the same as the newest generation of Super Cruise coming in the Cadillac CT5 and CT4. ItÂ’s an improved version with more capability than the first-gen system that won AutoblogÂ’s Technology of the Year award a couple of years ago. Questions still remain to be answered, though. GM hasnÂ’t said anything about what it will cost on the Sierra 1500. WeÂ’re also left in the dark when it comes to other Sierra 1500 trim levels; and what about the Silverado 1500? It makes sense that GM would give the Sierra Super Cruise first, but itÂ’s certainly compatible with the Chevy version of the truck now, too. As for other GMC products, GM is quiet on when theyÂ’ll be blessed with Super Cruise. The redesigned Yukon would be the most obvious candidate being the flagship product, but GM says the program timing worked out best to launch on the 2022 Sierra, not the Yukon. ItÂ’s likely that the SUV will be updated with the system in the near future. Besides Super Cruise, GMCÂ’s photo also reveals that the 2022 Sierra is getting a fully digital instrument cluster. ItÂ’s surely an optional item, but could very well be standard on Denali. GM has flipped the speedometer and tachometer to opposite sides, but their digital versions still have that straight-edged GMC look to them. You can see the Super Cruise graphic in the center, and all the gauges are dropped down to the bottom of the display. But wait, thereÂ’s more. The photo also shows the beginnings of a totally new interior design, different from both the current Sierra, standard Yukon and Yukon Denali interiors. ItÂ’s immediately and obviously different everywhere we look.

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.
