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 to reveal Hellcat-powered Challenger in Detroit?

On top of all the other performance car debuts slated for next week's Detroit Auto Show, we might be able to add one more to the list - the new, supercharged Hellcat V8 from Chrysler. According to new reports, the rumored 640-horsepower mill is likely to cross the Motor City stage in the engine bay of a Dodge Challenger.
As AllPar points out, though, there may be more news than just the fire-breathing engine. While we've seen spy photos of the Hellcat testing under the hood of the current Challenger, there's a very fair chance that it won't arrive until the muscle car is refreshed later this year. The question now is whether that refresh will be shown off alongside the new engine in Detroit, or if it'll be saved, perhaps for the New York Auto Show.
Other details dug up by AllPar include potential transmissions for the supercharged engine - the Mopar-minded site is expecting an eight-speed automatic or a Tremec six-speed manual. Prices, meanwhile, could be in the same elevated range as the Chevrolet Camaro Z/28, at $70,000 to $80,000.

Nine cars we wish were convertibles

The snow has melted, the sun is shining, and the days are getting longer. At the Autoblog Detroit office we feel like our winter hibernation is finally over. And with warmer temperatures come visions of opening up a convertible roof and cruising. You know, just turn up the bass and let the Alpine blast. There are plenty of droptops on sale in the US, and more on the way (like the 2016 Mazda MX-5 Miata). That said, we always want more. More! More! More! In that spirit, we cooked up a list of nine cars aren't currently sold as convertible, but ought to be. Check out our picks, below. Summer's just around the corner. Subaru BRZ / Scion FR-S In some parallel universe, this car actually happened. Toyota showed us a FT 86 Convertible concept at the Geneva Motor Show in 2013, and we immediately started licking our chops over the thought of a rear-wheel-drive convertible based on the Subaru BRZ and Scion FR-S twins. These days, the MX-5 Miata is our only option for affordable roadster fun. A competitor to the Mazda seems like a no-brainer to us, especially since we have naught but good to say about the BRZ/FR-S as-is. Unfortunately in our present timeline, this car is as likely for production as a BRZ STI. Which is to say, not very. Dang. Lexus RC F Unlike the FR-S, a convertible from Toyota's luxury division might actually see the light of day. The current IS convertible is about to be phased out, and the Lexus LF-C2 concept from the 2014 Los Angeles Auto Show is really a thinly veiled look at a possible RC convertible. A droptop RC would be plenty good, but let's reach for the starts. What we really want is to run topless in an RC F, complete with that powerful, loud, 5.0-liter V8 engine. Lexus says the RC F is a true competitor to the BMW M4. If that's true, it only makes sense for Lexus to mimic the Germans and offer its performance coupe in a folding hardtop form. Maybach Landaulet Maybach is bach back, recast as an upper crust trim level for Mercedes-Benz. The Mercedes-Maybach S600 is seriously awesome, and more luxurious than a trip to the spa. But why not go a step into the truly ridiculous levels of extravagence and bring back that open-top Landaulet? We think your local princess will love this idea, and with better S-Class bones underneath, Jeeves will have a pretty enjoyable ship to steer, too. Besides, with that slick new Mercedes design language, a Landaulet redux wouldn't be nearly as hideous as the old model, pictured here.
