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.

Performance doesn't matter anymore, it's all about the feel

We've just had a week of supercars and high-end EVs revealed. Many of them boast outrageous performance specs. There were multiple vehicles with horsepower in the four-figure range, and not just sports cars, but SUVs with 0-60 mph times under 3.5 seconds. And it's not just a rarified set of supercar builders, comparatively small tuners are also building this stuff. Going fast is easy nowadays and getting easier. So what will distinguish the greats from the wannabes? It's all about how a car feels. This may seem obvious. "Of course it matters that a car should have good steering feel and a playful chassis!" you say. "Why are you being paid for this stuff?" But a lot of automakers have missed the memo. This past week I spent some time in a BMW M4 Competition convertible, and it's a perfect example of prioritizing performance over experience. It boggles my mind how a company can create such dead and disconnected steering; the weight never changes, there's no feel whatsoever. The chassis is inflappable, but to a fault, because it doesn't feel like anything you're doing is difficult or exciting. The car is astoundingly fast and capable, but it feels less like driving a car and more like tapping in a heading on the Enterprise-D. I also happened to drive something of comparable performance that was much more enjoyable: a Mercedes-AMG GT. It was a basic model with the Stealth Edition blackout package, and even though it had a twin-turbo V8 instead of a six-cylinder, it only made 20 more horsepower. The power wasn't the big differentiator, it was (say it with me) the feel. While not the best example, the steering builds resistance as you dial in lock, giving you a better idea of what's happening up front. Pulses and vibrations come back to you as you move over bumpy pavement in corners. The chassis isn't quite as buttoned down, either, providing a little bit of body roll that tells you you're pushing it. It's also easier to feel when the car is wanting to understeer or oversteer, and how your throttle and steering inputs are affecting it. The whole thing is much more involving, exciting and fun. 2021 Mercedes-AMG GT Stealth Edition View 8 Photos That's also to say nothing of the Merc's sounds. That V8 is maybe not the best sounding engine, but its urgent churn through the opened-up exhaust gets your heart racing. It also seems like it's vibrating the whole cabin, so you feel it as much as you hear it.

Dodge engineers trying to shoehorn Pentastar into Dart?

The fact that the Dart's launch has been a pretty dismal affair isn't what we'd call secret. Judging by its mounting inventories and poor critical reception, Dodge's successor to its unloved Caliber has struggled since it hit the market. And while both of those are difficult problems to address, at least their cause is well known - the powertrain.
Even Fiat-Chrysler CEO Sergio Marchionne has acknowledged that the powertrain options in the Dart are substandard, admitting at January's Detroit Auto Show that the powertrains are "less than ideal." Leading with the 1.4-liter turbocharged four-cylinder found in the Fiat 500 Abarth left a bad taste in the mouths of consumers thanks to the laggy engine and dead throttle response (to say nothing of the manual and dual-clutch gearboxes that needed more refinement). The addition of the 184-horsepower 2.4-liter Tigershark in the Dart GT has helped matters some, but apparently Auburn Hills doesn't think it's quite enough.
If rumors are to be believed - get that salt ready - a possible solution may be in the works. A report from Allpar is claiming that Dodge is considering fitting a Pentastar V6 into the Dart's engine bay. As the Mopar-obsessed website points out, the critically acclaimed Pentastar is available in three different sizes - 3.0 liters, 3.2 liters and the original 3.6 liters. We don't get the 3.0 here in the US, but the 3.2 can be found in the new Jeep Cherokee and the 3.6 has been seemingly fitted to every model Chrysler can shoehorn it into.
