Chrysler says its 8-speed transmissions will save 700 million gallons

Chrysler Group's TorqueFlite eight-speed transmission could be earning some serious green bragging rights if the company's projections are correct. The recently widely proliferated automatic gearbox, which is now in more than a million vehicles around the world, is poised to save drivers an estimated 700+ million gallons of fuel over the vehicles' lifetimes (an expected cost savings of $2.5 billion). In addition, Chrysler expects a reduction in CO2 emissions by more than six million metric tons. According to Chrysler, and depending on the vehicle, the TorqueFlite can improve fuel economy. The TorqueFlite autobox features particularly close ratios from fifth to eighth gear (see the press release below for the specific numbers), and uses low-viscosity fluid that doesn't need to be replaced. Transmission software adapts to the driving situation to optimize efficiency based on driver behavior, temperature, grade, stability control, and longitudinal and lateral acceleration. The TorqueFlite is capable of handling a variety of duties. As evidenced by the wide range of vehicles Chrysler Group has seen fit to equip with the eight-speed transmission, the TorqueFlite is capable of handling a variety of duties. Since its 2012 introduction, the TorqueFlite has gone from performing cog-swapping duties in Dodge Charger and Chrysler 300 models equipped with the 3.6-liter Pentastar V6 to changing gears in vehicles such as the Pentastar- and Hemi-powered Dodge Durango, Jeep Grand Cherokee and even the Ram 1500 EcoDiesel. For the 2015 model year, the eight-speed is finding its way into even more vehicles with the addition of a third version. In addition to the American-made TorqueFlite 845RE and 8HP70, the new 8HP90 will be manufactured in Saarbrucken, Germany. The 8HP90 is designed for higher torque loads, making it ideal for high-performance vehicles like the 2015 Dodge Challenger SRT Hellcat. The already-in-use 8HP70 will expand its duties to be used in 2015 Hemi models such as the Dodge Charger, Challenger, and Challenger SRT8. You can see the list of those benchmarks in Chrysler's press release below.

Dodge revives Challenger T/A and Charger Daytona trims for 2017

Dodge is reviving the Challenger's T/A trim and the Charger's Daytona line for 2017. Introduced on iconic Woodward Avenue just days before the annual Woodward Dream Cruise kicks off, the new variants promise more performance hardware and sportier aesthetics. We'll start with the two-door. The Challenger T/A, available with either the R/T trim's 5.7-liter V8 or the fire-breathing 6.4-liter Hemi V8, is inspired by the Challenger T/As of old. That means a less restrictive, 2.75-inch active exhaust system and a conical Mopar air filter. But there's no clear bump in output – Dodge still lists the base 5.7-liter at 375 horsepower and the 6.4-liter model at 485 hp. But hey, they're going to look cooler. Unlike the Challenger Hellcat, which should have it as standard, Dodge is including a Satin Black hood on every Challenger T/A. In fact, Satin Black is a recurring theme on this Challenger's front fascia, roof, rear decklid, and T/A bodyside stripes. And yes, the 20-inch Mopar wheels are black, too – they're also an inch wider than normal. Dodge is offering the T/A in three different trims. The base T/A has everything we described above, while the T/A Plus adds some comfort features like heated and vented Nappa leather seats, an 8.4-inch UConnect system with Apple CarPlay/Android Auto, a six-speaker stereo, and a shortcut button for the Dodge Performance Pages. The T/A 392, meanwhile, adds the 6.4-liter V8, even wider wheels, and Brembo six-pot calipers. If you prefer smoking tires with four doors, there's the new Charger Daytona. No, there's not an enormous wing on the back. But Dodge added the same kind of engine/exhaust upgrades found on the T/A while upping the top speed from 135 to 150 miles per hour. Satin Black features prominently again, with hood and rear fender graphics. The roof is also black. Unlike the Challenger, Dodge is only offering two different versions of the Daytona – the 5.7-liter base model and the 6.4-liter version, called the Daytona 392. Prices for the Challenger T/A start at $38,485, including a $1,095-destination charge, while the T/A Plus adds $2,750. Adding the 392 means shelling out $45,090. For the Daytona, you'll need a check for $40,985 for the 5.7-liter or $46,090 for the 6.4-liter. Orders for the Charger Daytona open in September, while the T/A is a month later. Related Video:

Dodge Challenger spied exercising supercharged Hellcat Hemi V8

One of the prime complaints against the Dodge Challenger is that, even in SRT8 guise, its 470 horsepower is responsible for hauling over 4,200 pounds of vehicle. For comparison, the 420 hp in the Ford Mustang GT only has to deal with 3,618 lbs. Things only get worse from there, as the higher-performance variants of both the Mustang and the Chevrolet Camaro are far more powerful than an SRT8 without adding on much heft.
So what is Chrysler to do? The correct answer is add a whole lot more grunt to its hefty two-door and even the odds. That's where the all-new Hellcat engine comes into play. We reported on this engine in May, and suggested that the Hellcat, a supercharged powerplant based on a 6.4-liter V8, would easily generate 500 to 570 hp and could likely arrive boasting more than 600 ponies.
Chrysler's ace in its sleeve has now been spied testing, with a number of Hellcat-equipped Challengers running the potent new engine both in more urbanized areas and under the sun of Death Valley. The hoods on these testers have been raised to accommodate the engine, and that camouflage over the fascias of these prototypes is there to hide a larger air intake. We also note what appears to be a new split grille under wraps. As for power output, our spies are now suggesting a Viper-equalling 640 hp from the Hellcat-equipped cars.
