Chrysler resolves recall issue with NHTSA, will inspect, upgrade affected Jeeps

Chrysler made big news earlier in the month by refusing a recall request from the National Highway Traffic Safety Administration for the 1993-2004 Jeep Grand Cherokee and 2002-2007 Jeep Liberty. Last week, NHTSA boss David Strickland countered by defending his agency's request for the recall of 2.7 million Jeep SUVs. Today marked the deadline for Chrysler to formally respond to NHTSA, and it seems that both parties have met in the middle with Chrysler inspecting and upgrading some of the affected vehicles without using the word "recall," which would constitute the admission of a defect; instead, Chrysler said that it is conducting a "voluntary campaign."
At issue on these vehicles is the positioning of the fuel tank behind the rear axle that could get damaged during a rear-end collision. NHTSA has stated that at least 51 people have been killed in rear-end collisions involving these Jeeps after the vehicles caught fire, to which Chrysler countered by pointing out that both models "met and exceeded" the requirements for fuel-system integrity.
As a compromise on the situation, Chrysler says that it will inspect all pre-2004 Grand Cherokees and pre-2007 Liberty models and, "if necessary, provide an upgrade to the rear structure of the vehicle." According to Automotive News, this upgrade will consist of adding a trailer hitch that will presumably better protect the rear-mounted gas tank. Vehicles already equipped with a factory or Mopar hitch will not be modified. Chrysler's official statement on the matter is posted below, but no additional information has been released, such as when the campaign will begin and how many vehicles could be affected.

Watch this 650-hp Hennessey Jeep Grand Cherokee go from 0-60 in 3.9 seconds

Hennessey Performance Engineering has created an HPE650 package for the Jeep Grand Cherokee SRT fitted with the 6.4-liter Hemi engine. When it leaves the showroom floor it has 470 horsepower and gets from 0-60 miles per hour in 4.8 seconds. When it leaves Hennessey's garage floor after the upgrade it has 650 horsepower - 530 hp at the wheels, according to Hennessey - and gets to 60 mph in 3.9 seconds on its way to running the quarter-mile in 12.6 seconds.
There's more than just a Roots-type supercharger bolt-on, with ported cylinder heads and high-flow headers among the many changes made to the engine. You can watch this pre-2014 facelift silver model prove its spec sheet on the drag strip in the video below.

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).
