Mopar teases four of 'nearly 20' SEMA Show concepts

Yesterday it was Chevrolet. Today, Mopar has dropped some SEMA knowledge, releasing a quartet of teaser images that give us some indication of what kind of cars, trucks, and crossovers Fiat, Chrysler, Dodge, Jeep, and Ram will be showing in Las Vegas. Like Chevy, Mopar's concepts utilize both production and concept accessories, although Fiat Chrysler has gone a bit more indepth on at least one of its concepts. Immediately, the most tantalizing teaser is the one shown above. Yes, that's the back of a Challenger, and aside from the bright orange accents on the gray body, you should take notice of the badge mounted on the spoiler – yes, that says "GT AWD." To be honest, such a vehicle wouldn't be a huge shock, as both the Challenger's LX platform-mates, the Dodge Charger and Chrysler 300, are offered with all-wheel-drive options. Still, adding such a vehicle to the production cycle would give Dodge a leg up on the rear-drive only Ford Mustang and Chevrolet Camaro. Aside from that concept, FCA has also released teasers of a Ram-based concept, a 300-based concept, and what we're guessing is a Fiat 500X. We can't wait to see what the actual Fiat concept has to do with kiteboarding. As for the 300 and Ram, there's not a lot of hints on what sort of styling details they'll contain. The Chrysler has additional LED accents and what we're guessing is matte blue paint, while the Ram is based on a Hemi-powered 1500 with Rebel styling cues. This is just a very tiny sample of Mopar's final SEMA roster, which include "hundreds" of parts. There should also be a total of 20 vehicles covering all four former Chrysler Group brands, as well as Fiat. Naturally, we'll have plenty to report on each vehicle once the SEMA show kicks off in the next couple weeks.

Ram 1500 TRX too tame for you? Hennessey cranks its Hemi V8 to 1,012 horsepower

Ram captured the top spot on the horsepower podium when it released the Hellcat-powered 1500 TRX in 2020. The truck's 702-horsepower output places it comfortably ahead of the Ford F-150 Raptor, at least for now, but American tuner Hennessey saw plenty of room for improvement. It added over 300 horses to the TRX's cavalry. Hennessey is a master in V8-ology, so it was only a matter of time before it injected more power into the TRX. It announced two models named Mammoth 900 and Mammoth 1000, respectively, and each number vaguely corresponds to the V8's new output. The 900's 6.2-liter produces 912 horsepower and 873 pound-feet of torque, increases of 210 and 223, respectively, compared to the standard TRX. Hennessey achieved these figures by upgrading the supercharger pulleys and making relatively basic changes to the intake and exhaust systems. Stepping up to the 1000 unlocks 1,012 horsepower and 969 pound-feet of torque, numbers that give the 6,300-plus-pound truck the uncanny ability to reach 60 mph from a stop in 3.2 seconds. It flies through the quarter mile in 11.4 seconds at 120 mph. Building a pickup with supercar-like acceleration required installing a bigger, 2.65-liter supercharger, adding high-flow fuel injectors, and recalibrating the ECU. Intake and exhaust modifications are on the menu, too. Surprisingly, it doesn't sound like Hennessey made significant internal changes to the engine or to the transmission, which suggests the standard components can handle a massive amount of power. Context is useful here. Released in 2013, the fifth and final generation of the Dodge-turned-SRT-turned-Dodge again Viper took 3.3 seconds to sprint from zero to 60 mph, and it logged an 11.5-second quarter-mile time. Previewed in a computer-generated sketch, the Mammoth 1000 (shown above) also receives 20-inch wheels wrapped by 35-inch off-road tires, a 2.5-inch suspension lift, custom bumpers on both ends, extra LEDs up front, electronic fold-out steps, plus an array of model-specific emblems. Inside, Hennessey added a numbered plaque. 200 units of the Mammoth 1000 will be available for the 2021 model year, and pricing starts at $135,350 including the cost of the donor truck (which carries a base price of $71,790) and a warranty valid for two years or 24,000 miles. Put another way, you get 30.6% more power than stock for about 40% more money.

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).
