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.

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.

NHTSA investigates FCA for SUVs that roll out of Park

The National Highway Traffic Safety Administration is opening a preliminary evaluation into the 2014 Dodge Durango and 2014-205 Jeep Grand Cherokee after 14 complaints of the SUVs rolling out of Park. An estimated 408,000 of them could be affected, if a recall is necessary. All of the current complaints submitted to NHTSA about the issue concern the Grand Cherokee, and the claims allege that the SUV can roll out of Park whether or not the engine is running. Some folks report that they check the indicator each time because the gear sometimes fails to engage. Among the 14 cases, there are five accounts of crashes and three injuries, including a situation with someone allegedly being rolled over. NHTSA's preliminary evaluations are meant to investigate "the scope, frequency, and safety-related consequence" of a reported problem. They don't necessarily lead to a recall.

The unintended motion has occurred with both the engine off and the engine running. ODI has also identified EWR field report data related to the alleged defect. The model year 2014 and 2015 Jeep Grand Cherokee vehicles are equipped with an electronic gear selector (shift-by-wire system). The gear selection is made by pressing the shifter-paddle forward or backwards; the shifter does not move along a gate path as with conventional gear selectors. A Preliminary Evaluation has been opened to asses the scope, frequency, and safety-related consequence of the alleged defect. The VOQs associated with the opening of this investigation are: 10733158, 10730952, 10683556, 10679497, 10583366, 10725429, 10715401, 10711893, 10676998, 10668651, 10662619, 10662308, 10605865, and 10567538.
