2015 Ram 1500 Rebel drops the crosshairs, muscles in with new snout

Emboldened by record sale and increasing market share, Ram continues to spin off derivatives of its fullsize pickup. Bowing at today's Detroit Auto Show, the 10th model based on Ram's 1500 series is the new-for-2015 Rebel, and it's designed to capture the affections of that exceedingly popular marketer's bogey, the "active lifestyle enthusiast." Ram officials figure they've already got the hunt/fish/camp crowd all sewn up with the 1500 Outdoorsman, so the Rebel's imposing snout strikes out in a different direction in search of extreme-sports types – namely customers with dirt bikes, side-by-sides, jet-skis and other powersports toys. If that has you envisioning the Rebel as a rival to the Ford F-150 SVT Raptor, think again – "It's not an extreme, desert-racer off-road type product," says Ram boss Bob Hegbloom. If you're seeking an analog from another automaker, look to the Toyota Tundra TRD Pro and we think you'll be in the ballpark. The Rebel's most distinctive styling element has to be its radical new grain-finish grille, which does away with Ram's longstanding crosshair motif in favor of an interlocking design that intentionally won't be for everyone. There are lighting changes, too, with black-bucket headlamps featuring LED accents and matching LED foglights. A non-functional twin-snorkel sport hood, tonneau cover with stamped logo, blacked-out taillamps and unique badges are other model telltales. The Rebel (where have we heard that name before?) makes good use of Ram's air suspension system as an easy way to raise the ride height by an inch, which in turn affords inch-longer suspension travel and lends the truck a more formidable stance while helping clear the 33-inch (LT285/70R17E) Toyo Open Country A/T tires. Flares swiped from the 2500 Power Wagon keep the wider rubber mounted on Rebel-exclusive 17-inch wheels nicely – and legally – tucked in. Further off-road-minded modifications include a close-cropped steel front bumper that offers an improved arrival angle as well as 360-degree tow hooks and replaceable center skid plate. Out back, dual exhausts tuck up into the bumper and out of harm's way, but you might be too busy staring at the billboard-sized RAM tailgate lettering to notice. Ram officials assure us the Rebel's suspension has been recalibrated to cope with the higher ride height and better off-road ability (mostly through the inclusion of Bilstein monotube shocks, a softer rear anti-roll bar and reworked jounce bumpers).

Ram Rebel TRX concept is a Hellcat-powered Raptor-fighter

Ford has proven that fast off-road trucks are awesome. Dodge has proven that ridiculously powerful supercharged V8s are awesome. Combining the two would theoretically be even more awesome. The Ram Rebel TRX, which was unveiled at the Texas State Fair, proves that theory. As you may have guessed from the intro, the Rebel TRX uses a supercharged V8. A version of the supercharged 6.2-liter V8 from the Hellcat twins (and, we suspect, the Jeep Grand Cherokee Trackhawk). Because of some new calibrations to make the engine more suited for off-road driving, it doesn't make the full 707 horsepower of the Charger and Challenger. But the TRX engine still cranks out 575 horsepower, which is a full 125 more than the new SVT Raptor. That's enough to propel the mega-sized truck to 100 mph in its off road terrain mode. Power is transferred through an 8-speed automatic transmission to all four wheels. At the back, the Rebel TRX has an electronic locking differential. The TRX also gets an updated version of the Ram's 4x4 Performance Control System featuring Normal, Wet/Snow, Off-road and - best of all - Baja modes. The latter mode is the one that will do triple digits through the desert. Of course a sweet powertrain needs chassis and tire upgrades to round out the package, and the Rebel TRX has plenty of improvements. The standard Ram 1500 frame is unchanged, but bolted to it are custom front control arms, internal bypass shocks at each corner and new springs. The changes bring suspension travel to a full 13 inches all around. It also provides enough space to fit massive 37 x 13.5-inch tires. Ram also added six-piston calipers with 15-inch discs at the front and 14-inch discs at the back. Finally, Ram gave all this heavy duty equipment a big, burly wrapper. The body is a full six-inches wider than the standard 1500 with large composite fenders to cover the aforementioned tires. The truck also has a vented and scooped hood based on the Ram HD. This was necessary to help cool the engine and provide vertical clearance for the supercharger. A large sport bar was added to the back and has provisions for carrying a pair of spare tires, plus an LED light bar on top. The truck also has a big steel skid plate up front, and a sweet integrated side-exit exhaust behind the doors. Inside, the truck gets plenty of leather, suede and carbon fiber. The front seats also have racing harnesses attached to a harness bar that spans the B-pillars.

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.
