The Rivian R1T has rapidly become a talking point in the automotive world, and for good reason. Breaking stereotypes of traditional trucks, the R1T delivers impressive performance metrics that rival sports cars, especially when it comes to acceleration. While trucks of old were often criticized for sluggish handling and braking, the electric Rivian R1T Performance model challenges these preconceptions head-on. Let’s delve into the stopping and turning capabilities of this groundbreaking EV truck and see how it redefines expectations.
Braking Prowess: Rivian R1T Stops Shorter Than You Think
One area where trucks have historically lagged behind cars is braking performance. However, the Rivian R1T Performance demonstrates a surprising ability to stop quickly and effectively. In testing, the Rivian R1T Performance achieved a 60-0 mph stopping distance of just 126 feet. To put this into perspective, this braking distance is shorter than some small sedans, highlighting the advanced braking system and overall engineering of the R1T.
The testers noted the brake pedal feel is superior to other trucks they’ve evaluated, providing commendable feedback to the driver. Furthermore, engaging Sport mode and the firmest suspension setting minimizes nosedive during hard braking, enhancing stability and driver confidence. Interestingly, an earlier test of the Rivian R1T Launch Edition, which weighed slightly more at 7,148 pounds, recorded an even shorter stopping distance of 117 feet on the same test surface. This difference is attributed to variations in tire models, emphasizing how crucial tire selection is to vehicle performance. Even though both models used tires of the same size and brand, the tire construction on the R1T Performance didn’t offer the same level of grip as those on the Launch Edition.
Cornering Confidence: Rivian R1T Skidpad Performance
Beyond straight-line braking, handling is another domain where the Rivian R1T defies truck norms. On the skidpad, the Rivian R1T Performance achieved 0.85 g of lateral acceleration. This figure is remarkable for a vehicle of its size and weight, demonstrating agility and composure typically unexpected in a truck.
Reviewers were impressed by the R1T’s effortless handling, stating it “casually outhandling pretty much every other truck.” The vehicle’s systems work cohesively to make handling feel intuitive and easy. The steering wheel received praise for its slim rim and quicker steering rack compared to most trucks, contributing to a more responsive turn-in. Even in All-Purpose drive mode, the stability control effectively manages handling without being intrusive. Switching to Sport mode, lowering the ride height, and disengaging ESC allows for even greater cornering speed. While understeer is the primary handling characteristic, the Rivian R1T maintains a stable and secure feel throughout maneuvers. The potential for even greater handling prowess with enhanced torque vectoring and stickier tires was also highlighted.
Tire Tech: The Unsung Hero and Potential Limiter
The tires equipped on the Rivian R1T Performance during testing were Pirelli Scorpion Zero Elects, size 275/50R22, with a 500 treadwear rating and an HL (High Load) rating. These all-season tires are specifically designed for heavy electric vehicles, balancing load-carrying capacity, low rolling resistance for efficiency, and acceptable performance. The HL rating is a newer standard developed to accommodate the increased weight of EVs without requiring excessively high tire pressures, which can compromise ride comfort and increase noise.
However, the focus on load management and efficiency means that outright performance can take a backseat compared to tires designed purely for grip. The earlier tested Rivian R1T Launch Edition used Pirelli Scorpion Verde all-season tires (275/55R21) with a higher 600 treadwear rating and without the HL designation. This difference in tire construction likely contributed to the variations in braking and skidpad performance observed between the two R1T models.
Here’s a comparison of the test results:
Performance Metrics Compared
| Model | 60-0 mph Braking (feet) | Skidpad (g) |
|---|---|---|
| Rivian R1T Launch Edition (Quad-Motor) | 117 | 0.87 |
| Rivian R1T Performance | 126 | 0.85 |
| Ford F-150 Lightning Platinum | 127 | 0.78 |
| Ford F-150 Raptor R | 147 | 0.72 |
Range and Rolling Resistance: Tires Impact Efficiency Too
Beyond performance handling and braking, tires also significantly influence the range of electric vehicles. The EPA estimates for the Rivian R1T Performance Dual-Motor vary based on wheel and tire configuration: 307 miles with 20-inch all-terrain tires, 352 miles with 21-inch wheels, and 341 miles with the 22-inch wheels as tested. The 20-inch wheels paired with all-terrain tires present higher rolling resistance, reducing range, while lighter wheel and tire packages like the 21-inch configuration can improve efficiency by reducing the workload on the motors.
Conclusion: Rivian R1T Redefines Truck Performance
The Rivian R1T Performance impressively blends truck utility with sports car-like performance. While the 0-60 mph acceleration is a major highlight often discussed, its braking and handling capabilities are equally noteworthy, defying traditional truck limitations. The testing reveals that the Rivian R1T delivers commendable stopping power and cornering grip, positioning it favorably against both traditional trucks and even some passenger cars. However, the choice of tires plays a crucial role in realizing the full performance potential of the R1T, impacting not only handling and braking but also the overall driving range. As Rivian continues to innovate, further advancements in tire technology and vehicle dynamics promise to elevate the performance of electric trucks even further.
