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).

Jeep Grand One and Quicksand Concepts lead the charge to Moab

Jeep's past, present, and future all share equal billing at the 51st annual Easter Jeep Safari in Moab. We're suckers for vintage Jeeps, so the all-new Grand One Concept really stands out among the seven vehicles that make up Jeep's conceptual take on the off-road event. It's based on a 1993 Grand Cherokee in a slightly early celebration of the model's 25th anniversary. Exterior mods include custom fender flares for clearance over 18-inch wheels and 33-inch BFGoodrich Mud-Terrain KM2 tires, trimmed front and rear fascias and what FCA is calling a "subtle wood grain" splashed on the vehicle's bodysides. An extended wheelbase ought to offer a bit more room inside, and a two-inch suspension lift will help when the going gets tough. No alterations are mentioned to the vehicle's 5.2-liter V8 or 4-speed automatic transmission. The second most interesting concept for Moab is the Jeep Quicksand. It's clearly Wrangler-based, but instead of a traditional rock-climbing focus, this one's built for the sand dunes. Power comes from a worked-over Mopar 392 Crate HEMI engine topped with an eight-stack fuel injection system that peeks through the hood. A six-speed manual sends the ponies to all four wheels, but with a unique twist: 32-inch BFGs in the front and 37s in the rear in what Jeep says is its first application of staggered tire sizes on a concept vehicle. A Warn winch concealed in a vintage-style Moon tank at the front is the finishing touch. The Jeep Safari Concept is all about letting the outdoors in while keeping the elements out. A translucent hardtop and four aluminum and clear vinyl doors are the most obvious changes from stock, and two rear seats have been angled outward so that their occupants get a better view outside. Dana 44 axles and a two-inch suspension lift come from the Mopar parts catalog, but the roof-rack-mounted drone and dash-mounted iPad are custom one-off touches. Power comes from a stock 3.6-liter V6 and five-speed automatic transmission. Perhaps more intriguing than all the custom bits and baubles, though, are what appears to be next-gen Wrangler bodywork. Take a look at the kinked grille, the outer slats of which are pinched by the headlights, and the shape of the rocker panel between the front and rear door. No, this isn't exactly a 2018 Wrangler hiding in plain sight, but it's certainly a nod toward the future. Jeep's Switchback Concept looks to be a rolling Mopar parts catalog.

FCA issuing software update for 1.4M vehicles to prevent hacking

In the wake of a Jeep Cherokee being hacked remotely while on the road through its Uconnect infotainment system, FCA US is now issuing a software update for 1.4 million vehicles in the United States. Affected customers will receive a USB stick in the mail with the improved version; owners can check this website to see if their cars are affected. A large variety of models with FCA's 8.4-inch touchscreen infotainment system are affected. They include the 2015 Chrysler 200, 2015 Chrysler 300, 2015 Dodge Charger, and 2015 Dodge Challenger; 2013-2015 Dodge Viper; 2013-2015 Ram 1500, 2500, and 3500; 2013-2015 Ram 3500, 4500, and 5500 chassis cab; 2014-2015 Jeep Grand Cherokee and Cherokee; and 2014-2015 Dodge Durango. According to FCA in its announcement, the new software "insulates connected vehicles from remote manipulation." As of July 23, the company also "fully tested and implemented within the cellular network" additional security to prevent access to many of a vehicle's systems. FCA US says that it's conducting this campaign out of an abundance of caution and disputes the notion that there's a defect with these vehicles. Beyond the demonstration of the hack in the Cherokee, the automaker says that it's unaware of any other reports of these attacks actually happening. Related Video: Statement: Software Update July 24, 2015 , Auburn Hills, Mich. - FCA US LLC is conducting a voluntary safety recall to update software in approximately 1,400,000 U.S. vehicles equipped with certain radios. The recall aligns with an ongoing software distribution that insulates connected vehicles from remote manipulation, which, if unauthorized, constitutes criminal action. Further, FCA US has applied network-level security measures to prevent the type of remote manipulation demonstrated in a recent media report. These measures – which required no customer or dealer actions – block remote access to certain vehicle systems and were fully tested and implemented within the cellular network on July 23, 2015. The Company is unaware of any injuries related to software exploitation, nor is it aware of any related complaints, warranty claims or accidents – independent of the media demonstration.
