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.

MotorWeek proves '90s were awesome with Supra, Stealth, RX-7, Corvette, 968, 300ZX comparo

Oh, the heady days of 1993, back when the Clinton Presidency was just getting underway, and it seemed like every hot new rock band was coming out of Seattle. Sports cars in the US had finally shaken off the shackles that slowed them during the '70s and '80s, and you could buy any number of legitimately quick vehicles again. MotorWeek recently went digging into its archives to find this six-model test from 1993 showing off some of the best semi-affordable performance coupes that money could buy at the time, and it's priceless.
Featuring the 1994 model year Toyota Supra in twin-turbo guise and MY 1993 versions of the Porsche 968, Nissan 300ZX TT, Mazda RX-7, Dodge Stealth R/T Turbo and Chevrolet Corvette LT-1, MotorWeek definitely covered all of the bases. One thing that might surprise younger readers is these cars' performance. The video only provides 0-60 acceleration times, but several of these vehicles would still be considered pretty potent today - over 20 years since going on sale. The Supra is especially impressive, hitting 60 miles per hour in just 5 seconds. Even today, that's nothing to sneeze at.
Given their performance potential and still-attractive looks, it's amazing that some of these coupes are old enough to drink now. The progress of interior design and safety equipment in the intervening years is pretty shocking, though. In most of these models, having two airbags is touted as a big deal. Scroll down to watch a Throwback Thursday blast from the past about some of the '90s best sports cars.

Common Dodge Ram 1500 vs. Chevrolet Silverado breakdowns

These two trucks are famous for their ability to get the job done. Still, even the toughest vehicle can have mechanical problems at some time. What if we match the Dodge Ram 1500 and Chevrolet Silverado head to head? Let's find out more about common repairs for each model. Also, learn some tricks to pay for car repairs. Clunky Steering Both Dodge and the Chevy owners sometimes notice bumping and clunking when steering. This might be more noticeable when driving over bumps. The cause is usually different in each truck though. In the Dodge Ram, clunky steering is more likely due to a defective lower ball joint. Replacement costs around $300 - $400, parts and labor. Clunky Chevy Silverado steering is probably a steering rack failure. This problem appears more often in trucks with over 90,000 miles. Silverado steering rack repair will run you up to $1,000 or more. Starting Woes For the Chevy Silverado with over 130,000 miles, you might notice trouble starting. This problem may appear occasionally at first, but it typically gets worse. Excluding a weak battery, the culprit is usually the starter. Replacement will cost you around $330 - $500. Of the total cost, $90 is for labor only. Now the Dodge Ram might make a ticking sound when starting, especially on models with over 94,500 miles. The noise often disappears after the engine warms up. These symptoms may indicate a broken exhaust manifold. Repair costs range from $800 - $900. Burning Oil & Gas Gauge On The Blink Sometimes, the Dodge Ram burns oil much faster than normal. In models with over 125,000 miles, this often points towards a leaky intake manifold gasket. A knocking sound may also appear with acceleration along with possible engine misfire. The cost to repair is around $200 - $300. The Chevy Silverado has its own surprises, especially when you've filled the gas tank but the gauge still reads low. Or the needle fluctuates widely from low to full while driving. In trucks with over 120,000 miles, it's likely due to a faulty fuel sensor. You might need a full fuel pump replacement, which can cost you up to $820, parts and labor. Water Inside And Poor Heat The Ram 1500 rear window has been known to leak. You might notice the back seat and floor wet after a rainstorm. This is more common in trucks with over 65,000 miles. Resealing the Ram 1500 rear window costs around $150 - $250.
