Hellcat no help to Fiat-Chrysler's bottom-of-the-pile mpg average

What, you expected the "fastest muscle car ever" to help fleetwide fuel economy? Nope, don't think that's going to happen. That means Fiat Chrysler will likely to continue to languish at the bottom of the heap when it comes to fleetwide fuel economy among the largest automakers serving the US, especially as the automaker starts to sell its Dodge Challenger SRT Hellcat. A few hundred Fiat 500E electric vehicles aren't going to turn the trend around. See, Chrysler has once again finished at the bottom of the list when it came to fleetwide fuel economy among automakers for 2014 model-year vehicles, according to a preliminary study by the US Environmental Protection Agency. Chrysler and Fiat had an average of 21.1 miles per gallon. That substantially lagged the overall 24.2 mpg average, but it was an increase from the company's 20.9 mpg average last year and the 20.1 mpg average two years prior. For 2014, General Motors had the second-worst fleetwide fuel economy at an even 22 mpg. Fiat Chrysler does say it's working on improving its fuel economy, according to Automotive News. The company plans on making its inline-four-cylinder and V6 engines smaller, and will sell more vehicles with eight- and nine-speed transmissions. Heck, there's even a plug-in hybrid version of the Chrysler Town & Country minivan in the works for late 2015, and the company can tout fuel-efficiency gains with the Chrysler 200 and Jeep Cherokee. We would be remiss if we didn't note that, compared to its muscle-car forefathers, the Hellcat actually performs pretty well at the pump. Last month, word got out that the 2015 Challenger Hellcat, equipped either with a six-speed manual or an eight-speed automatic transmission, got a combined fuel economy of 16 mpg. Heck, the automatic-tranny version got 22 mpg on the highway. And that's for a car with 707 horsepower and a 10-second quarter-mile time. Still, with the pedal floored, the car can burn a gallon and a half of fuel per minute. Ouch.

NHTSA investigating Chrysler for airbags, ignition switches

Chrysler is being targeted by the National Highway Traffic Safety Administration in a pair of actions that focus on over 1.2 million Jeeps, minivans and crossovers.
The first is a "preliminary investigation" that focuses on an airbag issue afflicting the Jeep Commander built in model years 2006 and 2007 and Grand Cherokee from 2005 to 2006. In total, 700,000 vehicles could potentially be affected. It's not entirely clear what the airbag issue is, with The Detroit Free Press simply stating that the restraint systems in the affected Jeeps may be "faulty."
The other investigation is what's called a "recall query" and it covers a problem that General Motors should be familiar with. In this case, there could be a problem with the ignition switches of 525,000 vehicles, ranging from 2008 to 2010 Chrysler Town & Country and Dodge Grand Caravan minivans, to the 2008 to 2010 Dodge Journey crossover. Again, it's not entirely clear what sort of behavior prompted the 32 complaints that NHTSA has received on these vehicles.

Dodge Challenger SRT Demon TransBrake eliminates the need for brake torquing

Performing the perfect launch is key to drag racing. In order to get consistent starts, the engineers behind the Dodge Demon developed TransBrake, a system that holds the output shaft of the automatic transmission to keep the vehicle stationary until launch. Rather than the traditional method of two-foot brake torquing, the system is triggered by pulling the shift paddle for quick and consistent launches. According to Dodge, the main benefit of TransBrake versus a two-foot setup is a quicker power delivery and higher engine launch torque potential. The system gives brake-free launches up to 2,350 RPM, a 105-percent increase in launch boost pressures, and a 120-percent increase in engine launch torque. Dodge also claims that using the paddle provides a 30-percent better reaction when compared to using your feet. In addition to shifting duties from your feet to your hands, the Demon's TransBrake will preload the driveline. Torque is loaded at the wheels, not the transmission. That means full torque delivery 150 milliseconds after the shift paddle is released. It should also help reduce the driveline shock that occurs when those 315 section rear tires get near-instant grip. The reveal is coming near.
