2021 Ram 1500 TRX strapped to dyno, puts out 583 hp at the rear wheels

The 2021 Ram 1500 TRX boasts a factory-quoted 702 hp and 650 lb-ft of torque, but that’s as measured at the crank, not the wheels. Hennessey Performance Engineering tried to measure how much power the TRX makes at the wheels by strapping one to a dyno, but only ran numbers for the rear wheels.

The dyno test showed 538 hp and 570 lb-ft of torque at the rear wheels. That represents around 17% driveline loss, which isn’t unusal for a pickup truck. Hennessey previously recorded 20% driveline loss at the rear wheels when it tested a 2019 Ford F-150 Raptor.

The TRX is full-time four-wheel drive, so you might be wondering how Hennessey got dyno results for the rear wheels only. Company founder John Hennessey told Motor Authority that four-wheel drive was temporarily disabled by disconnecting the front driveshaft.

2021 Hennessey Mammoth 1000 1500 TRX

While the TRX was designed for off-roading, the amount of power produced by its 6.2-liter supercharged Hellcat V-8 makes this truck pretty quick on pavement. Ram says it will do 0-60 mph in 4.5 seconds.

Inevitably, that wasn’t enough for Hennessey. The company has developed more powerful versions of every Hellcat-powered vehicle, and it’s doing the same with the TRX. Dubbed the Mammoth 1000, Hennessey claims its take on the TRX will boast 1,000 hp, will do 0-60 mph in 3.2 seconds, and run the quarter mile in 11.4 seconds.

To achieve those numbers, Hennessey plans to equip the Mammoth 1000 with an upgraded supercharger, pulley, and air intake, stainless-steel headers, high-flow exhaust piping (retaining the catalytic converter), and new engine mapping. The price for the complete truck is $135,350, and Hennessey only plans to build 200 this year.

2022 Volvo C40 Recharge, 2021 Porsche Taycan, 2021 Honda Legend: This Week’s Top Photos

By 2030, Volvo will have a fully electric lineup and an online sales model just like Tesla. However, we won’t have to wait until then for new electric vehicles from the Swedish brand as it will already have seven available by the middle of the decade. One of the seven was revealed this week in the form of the 2022 C40 Recharge.

2022 Honda CR-V, 2021 Chevrolet Corvette, 2020 Audi SQ8: The Week In Reverse

The 2022 Honda CR-V was spotted, the 2021 Chevrolet Corvette became more expensive, and we drove the 2020 Audi SQ8. It’s the Week in Reverse, right here at Motor Authority.

The 2022 Honda CR-V was spotted undergoing testing with a light layer of camouflage. The small crossover SUV’s design will take an evolutionary step forward with design influence from the latest Accord sedan. The upcoming CR-V appears to be longer than the current model, and the interior will likely take cues from the redesigned Civic.

We now know what happens when you cross the Boot and 004 supercar from Scuderia Cameron Glickenhaus. It’s called the 008, and it looks like a safari version of the 004 triple-seat supercar. The mid-engine off-roader’s long-travel off-road suspension could make it eligible to tackle the Baja 1000.

The 2021 Chevrolet Corvette now starts above $60,000. Despite a $1,000 price bump across the lineup, the Corvette will remain a value. Other changes include new exterior color options, available full-length racing stripes, and wireless Apple CarPlay and Android Auto.

The National Hot Rod Association (NHRA) is the latest racing sanctioning body to take a serious look at electric cars. The organizers are asking for input on how to make electric cars a larger part of drag racing. The invitation for input includes, but is not limited to, automakers, aftermarket parts suppliers, race car builders, and safety equipment manufacturers.

Subtlety can be attractive, and the 2020 Audi SQ8 is an understated performance crossover SUV. A twin-turbo 4.0-liter V-8 pushes this four-ringed crossover to 60 mph in 4.3 seconds despite its 5,324-lb curb weight. It’s one quick way to get to Starbucks. There’s no question the SQ8 is worth the $20,000 upcharge over the base Q8.
