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.

1968 Dodge D200 'Lowliner' adds low-down diesel torque to a lowrider

When Mopar does a custom classic car, it's always spectacular, whether it's a Dodge muscle car like the 1,000-horsepower Super Charger or the monster Jeep Five-Quarter off-road pickup. For SEMA this year, Mopar skipped another Dodge sports coupe in favor of a 1968 Dodge D200 pickup truck done up as a lowrider, but with a twist. Or more accurately, with lots of twist. Under the gorgeous candy red metallic body is a 5.9-liter 24-valve Cummins turbodiesel straight-six. It makes an estimated 325 horsepower and 610 pound-feet of torque, and it's paired with a six-speed manual transmission. Representatives from Chrysler estimated the weight of the engine and transmission alone at 1,100 pounds. The diesel engine's power goes to the rear wheels, which are 22 inches in diameter and 11 inches wide with fat 325-mm tires. The front wheels are a tad narrower at 9.5 inches. 1968 Dodge D200 View 7 Photos As cool as the powertrain is, the exterior and the interior of the truck can't be ignored. This generation of Dodge pickup is already intriguing with its distinct character line with a little kink at the end and ribbed and louvered hood. These unique styling cues are accented now that Dodge removed various other details from the body such as the door handles, metallic trim and such. The bumpers were also reshaped to better fit the contours of the body, and the front wheels were pushed forward to reduce the long overhang of the stock truck. The bumpers, grille, and "smoothie" style alloy wheels were also painted in a solid cream color rather than chrome, which both accents the deep red body and gives the truck a more workmanlike feel, as low-trim cars typically had painted trim instead of chrome or stainless steel. The red paint also features subtle Cummins logos on the fenders and Dodge block lettering on the tailgate. The interior continues the simple and classy theme. The original bench seat remains, but with saddle brown leather upholstery. Leather trim has been added throughout, and exposed metal parts have been painted in the same color as the exterior. Simple gray cloth floor mats cover the bottom of the cab, and the instrument panel uses new Mopar gauges in a machine-turned metal housing. The original steering wheel remains, but a custom shifter with red Cummins shift knob sticks through the floor.

Stellantis expects to hit emissions target without Tesla's help

Franco-Italian carmaker Stellantis expects to achieve its European carbon dioxide (CO2) emissions targets this year without environmental credits bought from Tesla, its CEO said in an interview published on Tuesday. Stellantis was formed through the merger of France's PSA and Italy's FCA, which spent about 2 billion euros ($2.40 billion) to buy European and U.S. CO2 credits from electric vehicle maker Tesla over the 2019-2021 period. "With the electrical technology that PSA brought to Stellantis, we will autonomously meet carbon dioxide emission regulations as early as this year," Stellantis boss Carlos Tavares said in the interview with French weekly Le Point. "Thus, we will not need to call on European CO2 credits and FCA will no longer have to pool with Tesla or anyone." California-based Tesla earns credits for exceeding emissions and fuel economy standards and sells them to other automakers that fall short. European regulations require all car manufacturers to reduce CO2 emissions for private vehicles to an average of 95 grams per kilometer this year. A Stellantis spokesman said the company is in discussions with Tesla about the financial implications of the decision to stop the pooling agreement. "As a result of the combination of Groupe PSA and FCA, Stellantis will be in a position to achieve CO2 targets in Europe for 2021 without open passenger car pooling arrangements with other automakers," he added. Tesla's sales of environmental credits to rival automakers helped it to announce slightly better than expected first-quarter revenue this week. The next tightening of European regulations will soon be the subject of proposals from the European Commission. The 2030 target could be lowered to less than 43 grams/km.
