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

2021 Hennessey Mammoth 1000 1500 TRX

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 disabled by disconnecting the front driveshaft.

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 Audi Q4 E-Tron, 2022 Hyundai Santa Cruz, Mercedes-Benz AMG One: This Week’s Top Photos

Published

2022 Mercedes-Benz EQS

Audi expanded its lineup of electric vehicles with the reveal of the new Q4 E-Tron and Q4 Sportback E-Tron. The handsome compact crossover duo arrive at dealerships later this year and should offer around 250 miles on a charge.

2022 Mercedes-Benz EQS

Another new electric vehicle in the headlines this week was the 2022 Mercedes-Benz EQS, and it did not disappoint. The svelte electric sedan combines an S-Class grade interior with impressive technology, and this should help it attract well-heeled buyers looking to make the switch from gasoline to electrons.

Nissan GT-R Nismo Special Edition

Nissan is close to launching a redesigned Z, but the automaker’s other sports car, the GT-R, will soldier on in its current form for a little while longer. This week, Nissan introduced a special version of the GT-R Nismo range-topper. It features a unique look and upgraded engine internals.

2021 Volkswagen Arteon

Volkswagen updated the Arteon for 2021, adding new technology and styling tweaks that push the svelte sedan even closer to near-luxury status. This week we posted up our review of the car.

2021 Toyota Supra

Another car we tested was the 2021 Toyota Supra, specifically the 6-cylinder. The car’s got gobs of power, but the same enthusiasts who are eager for this might find the lack of a manual gearbox unforgivable.

Development of Mercedes-Benz AMG’s Formula One-powered hypercar is almost complete, with prototypes this week hitting the Nürburgring for the first time. While the One may be delayed, the wait will definitely be worth it for the 275 future owners.

Another car testing on the ‘Ring was a high-riding Porsche 911. Porsche has said such a car would be a good idea, and now it looks like one is coming.

2022 Hyundai Santa Cruz

And finally, Hyundai revealed its 2022 Santa Cruz. The compact pickup truck is related to the Hyundai Tucson, and we’ll see it at dealerships this summer.

Filling in for the Chinese Grand Prix

Autodromo Internazionale Enzo e Dino Ferrari (Imola)

Round two of the 2021 Formula One World Championship takes us to historic Imola in Italy this weekend, where a special race, the Made in Italy and Emilia Romagna Grand Prix, is being held.

The race fills in for the usual Chinese Grand Prix which was canceled this year due to disruptions caused by the ongoing Covid-19 pandemic. This will be the second year in a row that the Imola racetrack, officially the Autodromo Internazionale Enzo e Dino Ferrari, hosts an F1 race.

The anti-clockwise circuit, which in previous times has hosted the Italian and San Marino Grands Prix, has been in continuous use and updated considerably over the years. For instance, the old Variante Bassa is gone and the long straight heading into Tamburello is now broken up by two right-hand corners. More run-off areas have been added, especially at Variante Alta.

As for the track itself, it stretches 3.08 miles and is quite narrow in places, which adds to the challenge of overtaking and puts an emphasis on strategy. Although it was given fresh asphalt prior to last year’s race, it is still quite bumpy and there are some big curbs, placing notable demands on the cars and drivers.

Just over 70 percent of a lap is taken at full-throttle, the third-highest percentage of the 2021 F1 tracks. This includes 15 seconds of foot-to-the-floor lap time from the exit of the final corner to the braking zone for Turn 2.

Looking at the weather forecast, we should be in for fine conditions for most of the weekends. However, there’s a chance we could see some rain during Sunday’s race. Pirelli has nominated its mid-range C2, C3 and C4 tires for the race.

Following the first practice session on Friday, Mercedes-Benz AMG’s Valtteri Bottas was the quickest, followed by fellow Mercedes driver Lewis Hamilton. Rounding out the top three was Red Bull Racing’s Max Verstappen who hopefully will challenge the Mercedes duo for victory like he did in the season opener in Bahrain.

Going into Saturday’s qualifying and Sunday’s race, Hamilton leads the 2021 Drivers’ Championship with 25 points. Verstappen is second with 18 points and Bottas is third with 16 points. In the Constructors’ Championship, Mercedes leads with 41 points, versus the 28 of Red Bull and 18 of McLaren. Last year’s winner at Imola was Hamilton driving for Mercedes.

Electric Ferrari locked in for 2025

Published

John Elkann

Ferrari will unveil an electric vehicle in 2025, Chairman John Elkann said on Thursday during the company’s annual general meeting.

The news of an electric Ferrari doesn’t come as a huge surprise as patent drawings filed by Ferrari for a modular electric drive system were discovered last year.

Elkann didn’t provide any details on the vehicle but former CEO Louis Camilleri in 2019 said the company was studying the potential for a grand tourer-style car, suggesting it won’t be a supercar like the upcoming Lotus Evija or Rimac C_Two.

Camilleri, who stepped down from Ferrari last year due to personal reasons, also said in 2019 that an electric Ferrari would eventually come, though only after 2025.

During Ferrari’s annual general meeting, Elkann also said that the search for Camilleri’s replacement was ongoing, and that the lucky man or woman will give an update on Ferrari’s future plans during a capital markets day presentation to be held in 2022.

Recent rumors have pointed to Ferrari’s first EV being a crossover, which does make some sense as a heavy battery would be less likely to negatively affect the performance of a crossover compared to a supercar. Ferrari next year will launch its first crossover, the Purosangue, and according to the rumors the platform of the high-riding Prancing Horse has been designed to support electric powertrains.

Ferrari in the past has flip-flopped on the idea of launching an electric car but stricter emission rules and changing market trends has likely convinced the automaker of the need for having one. The company has previously cited a lack of suitable battery technology as the main hurdle.

While an electric Ferrari is still a few years off, the company will focus on plug-in hybrid technology in the interim. The company has just launched the plug-in hybrid SF90 Stradale and targets a 60-percent electrified lineup by 2022. The company is also looking into more alternatives, such as using hydrogen or biofuels.
