GM 6.2L V8 claims most powerful light-duty truck engine title

General Motors has officially captured the horsepower crown for mainstream pickup trucks with its 6.2-liter V8. The big mill, available in both the Chevrolet Silverado and GMC Sierra, comes to market with 420 horsepower and 460 pound-feet of torque, handily outdoing its two cross-town competitors, Ram (5.7-liter V8, 395 ponies and 407 lb-ft) and Ford (6.2-liter V8, 411 hp and 434 lb-ft).
The new GM 6.2 will take a bit of an investment, though. Those that want the extra thrust will need to go with either the LTZ or High Country trims from the Chevy, or the SLT and Denali trims from GMC, which are the two highest trim levels for the respective vehicles. Trim levels aside, if you're in the business of towing, GM has you covered. Optioned with the 6.2-liter V8 and the Max Trailering Package, owners will be able to pull 12,000 pounds, a hugely impressive figure.
We still aren't certain as to what sort of economy the new engine will get, but it'll probably be a bad bet for the fuel conscious. As for availability, expect to see the 6.2-liter trucks in showrooms later in the fall.

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).

How the Ram Multifunction Tailgate compares to Ford, GMC, Honda

Ram just announced its Multifunction Tailgate — a descriptive if not very creative name. It's an asymmetrical barn-door arrangement, which can both fold down like a conventional tailgate or swing open like a gate. There's a new bed step, but unlike Ford or GM, the step isn't part of the tailgate itself. Rather, it kicks out from under the bumper (as opposed to out from under the driver's side of the rear bumper in its previous incarnation). So let's just focus on the tailgate functionality. A video of the Ram Multifunction Tailgate in action is above. For one, either of the swinging tailgate sections can be opened independently. They open to a full 88 degrees. In conventional flip-down mode, the tailgate works just like a normal one, too, with a 2,000-pound rating. The bottom line is that while it gives a variety of types of access to the load area, it doesn't "do" anything else. It's a $995 option on any Ram 1500. Its closest analogue is the Honda Ridgeline, which works basically the same way, but on that truck the tailgate swings as one piece. And the Honda's load rating isn't as hefty as the Ram's tailgate: 300 pounds. As Honda says, that's sufficient to hold the weight of the part of an ATV hanging out of the bed, or something similar, but it's a lighter-duty unit (and a lighter-duty truck) than the Ram's overall. Let's also get Ford's one-trick tailgate out of the way before comparing to the more analogous, and complicated, GM MultiPro. A bit of trivia: Ford's optional Tailgate Step is actually designed and supplied by Multimatic, better known as the outfit that builds the Ford GT and produces the DSSV spool-valve shocks. This step has been available for years. It pulls out of the top edge of the tailgate when the tailgate is lowered, deploying a single step. A separate handle pulls out from beside the step and flips up, giving a handhold. While it was initially (and infamously) mocked by competitors, with load floor heights as high as they are it's better than toting around a stepstool. It's currently a $375 standalone option. Now we get to the GMC MultiPro tailgate, the most complicated and multi-functioned around. It's essentially a tailgate within a tailgate, with a fold-out stopper that deploys from the inner tailgate. This gives it several functions depending on the position of all the parts. It can still be used like a normal tailgate, dropping down at the push of a button or using the key fob.
