Out of Spec: Rivian R1T vs. Cybertruck Highway Range Test! Don't Trust The EPA Rated Difference, Surprising Result

[Administrator]

ChatGPT summary:

The video appears to document a detailed range test comparison between the Tesla Cybertruck and the Rivian R1T under specific conditions. Below is a summary of key points from the first portion of the video, with timestamps for notable moments:

Key Points:

• Cold Weather Range Test Introduction (0:59)
  The test takes place under deteriorated weather conditions, featuring cold temperatures and crosswinds. This affects the overall range and efficiency for both vehicles. The Cybertruck and Rivian R1T are tested in their longest-range configurations.
• Setup & Testing Procedures (3:57)
  • Both trucks are charged to 100% and preconditioned for optimal battery performance.
  • The test involves a drive along a 70 MPH highway route until the vehicles run out of charge.
  • Both vehicles use different drive modes and configurations to maximize efficiency.
• Sponsorships & Collaborations (5:11)
  The video highlights sponsors like Amber, Star Charge, Eaton, and Climate Exchange, which is hosting an EV raffle with substantial cash prizes.
• Vehicle Setup Details (9:55)
  • The Cybertruck uses a smaller 123 kWh battery compared to Rivian's 141-144 kWh pack.
  • Tesla's aerodynamic design and unique shape potentially contribute to its efficiency despite a smaller battery.
  • Drive modes: Rivian utilizes front-wheel drive for efficiency, while Cybertruck operates with its rear motor in chill mode.
• Mid-Test Observations (20:47)
  • Early results suggest the Cybertruck is slightly more efficient, even though it has a smaller battery and larger size.
  • Wind and cold weather influence the efficiency of both trucks significantly.
• Challenges & Anecdotes (31:30)
  • Rivian's driver assistance system temporarily malfunctioned but was restored after a reset.
  • Some quirks of the Cybertruck include its unique aerodynamic shape potentially aiding in efficiency.

Observations:

• Efficiency Trends: The Cybertruck seems to hold an efficiency edge in certain conditions despite its unconventional shape.
• Weather Impact: Crosswinds and cold conditions have a noticeable impact on the range, showcasing the importance of weather in real-world testing.

TLDR: 14 mile real world difference but they're thinking weather conditions affected the test more than anticipated. The video has a good summary in the last 3 minutes.

Did it discuss tires? It looks like the screenshot has the AT tires on the Cybertruck.

 

[TripleB]

Don't have 1.5 hours. Distance of both? Is the CT on stock tires?

Weird dig at a repeated scientific averaged test vs an anectodical one-off.

Grok 2 summary:


Video Summary:

- Range Test Setup: The video features a range test comparing the Tesla Cybertruck and the Rivian R1T. Both vehicles are driven at a constant highway speed of 70 mph until they run out of battery, with the goal to see how their real-world range compares to their EPA-rated range.

- EPA Ratings vs. Real-World Performance:
- The Rivian R1T with the Max Pack has an EPA-rated range of 410 miles, while the Tesla Cybertruck's range (not specified in the summary context) is generally less according to EPA ratings.
- Despite the EPA ratings, the results of the test show that the Cybertruck actually outperformed the Rivian in real-world conditions, achieving more miles on a single charge than expected.

- Test Results:
- Rivian R1T Max Pack: Achieved 345 miles before running out of charge, which is below its EPA rating of 410 miles.
- Tesla Cybertruck: Managed to go 304 miles, which was closer to its EPA estimate, suggesting better efficiency in this particular test scenario.

- Key Points:
- The test highlights that EPA ratings can be misleading, especially under consistent highway conditions where factors like aerodynamics and vehicle efficiency play significant roles.
- The Cybertruck's performance was surprising given its lower EPA rating, suggesting that it might handle real-world highway driving more efficiently than anticipated or that the Rivian's larger battery doesn't translate to proportional range gains under these test conditions.

- Additional Insights:
- The video discusses factors like battery efficiency, vehicle weight, tire type, and aerodynamic design, which could explain the observed discrepancies in range.
- It also touches on the implications of these findings for prospective buyers considering these electric trucks for long-distance travel.

- Conclusion: The video concludes that while EPA ratings are useful, they do not always reflect real-world performance, emphasizing the importance of independent range tests for potential EV buyers.

This test serves as a reminder that real-world conditions can significantly affect an electric vehicle's range, and consumers should consider such tests alongside official ratings when evaluating vehicles like the Cybertruck and Rivian R1T for their needs.

wow, the cybertruck did really well.....305 miles highway in the cold, missing 3 aero flaps and with 99% charge....its shocking how close they were in the end

The other interesting element (did not watch the video, but recognize the truck), that is the Rivian R1T Gen 2 with the larger max pack battery. Kyle released a video a couple of days ago doing the 10% challenge and discussed the vehicle quite a bit (he likes his R1T Gen 1 much better).

It did not do 305... 250-something and the Rivian was 14 miles ahead. Shows the massive efficiency advantage the CT has despite being bigger. I live in the area and the weather that day was far from ideal to test. I'd expect both to be ~12-15% higher on a better day. I'd also hazard a guess that the Rivian's heatpump isn't as efficient as the CT so it might be a little more impacted by the weather.

I only watched the end where they are talking from inside the rivian and I thought he said 305 for the CT down from the rated 320 and with only 121 instead of 123 kW

Just looked at the end again, it was 252 vs 266. It was 121 kWh pulled from the truck, but that is never 100% exact. It wasn't great weather that day (I remember because I had to drive for hours that day too), so another +10% is pretty safe for both and I really think that +12-15% is closer. Honestly not a great showing for Rivian there. WAY off considering an 18 kWh larger battery.

Samples of one are not the best tests.
