Chrysler recalls small number of 2013-2014 cars and trucks over engine debris

Chrysler is recalling a small number cars over issues with their 2.4-liter four-cylinder engines. The recall, which affects 522 examples of its 2013 Dodge Avenger and Chrysler 200 models, as well as 2014 Jeep Compass and Patriot CUVs has to do with potential debris in the balance shaft bearings.
The abrasive stuff can cause the oil pressure to drop, which could lead to the engine stalling or outright failure. This situation could at best leave drivers stranded and at worst lead to a crash.
Chrysler will begin notifying owners, who will need to report in to have the balance shaft module replaced. All repairs are naturally free of charge. Scroll down for the bulletin from NHTSA.

2016 Dodge Viper ACR is ready to take a bite out of the Corvette Z06 [w/video]

The Dodge Viper ACR is back, and as Fiat Chrysler Automobiles tells it, it's the most venomous breed ever born. Before you get too excited, the 8.4-liter V10 produces 645 horsepower; five more than the standard Viper and five less than the supercharged Chevrolet Corvette Z06. It's unclear why Dodge didn't extract more from the huge engine, although we somehow imagine that certain people in Maranello, Italy had a say in the matter. Instead of blessing the ACR variant with bunches of extra output, Dodge instead turned to an aggressive aerodynamics package that it claims delivers nearly a ton of downforce at the Viper's maximum speed of 177 miles per hour. The total aero package includes an adjustable, twin-element, carbon-fiber rear wing, carbon-fiber diffuser, an extendable front splitter, and dive planes. Those big louvers on the hood? Yeah, they're removable, too. The "race-tuned" suspension uses coil-over Bilstein shocks that offer ten different settings and up to three inches of height adjustment. Kumho Ecsta V720 tires were built specifically for the Viper ACR, and come in 355/30 in back and 295/25 in front, with 19-inch wheels at all four corners. Along with the aero improvements, Dodge is claiming the Viper can pull a race-car-like 1.5Gs in higher-speed turns. Carbon-ceramic brakes with six-piston calipers add the stopping power that's greater or equal to the ACR's cornering performance. Dodge was also keen to reduce weight, taking some rather dramatic measures in the effort. The stereo has just three speakers, while the electric function was removed from the seats. Even the carpet has been replaced with a "lightweight" alternative. Finally, Dodge is offering up the innovative 1 of 1 customization it pioneered with the Viper GT earlier this year. That means that not only can you get the fastest Viper ever built, but it'll be entirely your own when you take delivery.

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).
