Rivian R1T vs Hummer EV Drag Race: Acceleration & Limits Tested
content: Electric Truck Drag Race Showdown
The battle of next-gen electric trucks boils down to two heavyweights: the tri-motor GMC Hummer EV and quad-motor Rivian R1T. In controlled testing by Throttle House, both vehicles started at 100% charge on the same surface, eliminating variables. The Rivian’s 2,000-pound weight advantage proved decisive despite the Hummer’s higher horsepower claims.
Technical Specifications Compared
| Metric | Rivian R1T | GMC Hummer EV |
|---|---|---|
| Motor Layout | Quad-Motor AWD | Tri-Motor AWD |
| Curb Weight | ~7,150 lbs | ~9,500 lbs |
| Launch Mode | Sport + Low Height | Watts to Freedom (WTF) |
| Top Speed Limiter | 115 mph | 106 mph |
Key Insight: The Hummer’s Watts to Freedom mode (reportedly "WTF" internally) activates dramatic pre-launch sequences including seat vibrations and futuristic sounds. Yet as Throttle House observed: "All that theater couldn’t overcome physics when the Rivian leapt ahead instantly."
Acceleration Test Results
Standing Start:
The Rivian’s immediate traction advantage delivered a 0-60 mph win. Its lower center of gravity and reduced mass allowed it to outpace the Hummer despite the latter’s 1,000-hp output. At 106 mph, the Hummer hit its electronic limiter while the Rivian reached 115 mph.
30-mph Roll Race:
Removing launch control from the equation, the Rivian’s weight advantage became even more apparent. It pulled away decisively, highlighting how mass impacts real-world performance beyond paper specs. The Hummer’s sheer bulk created noticeable "soupy" body roll during transitions.
Performance Limitations & Realities
- Speed Limiters: Both trucks cap top speeds (115 mph for Rivian, 106 mph for Hummer), prioritizing safety and battery longevity over outright velocity.
- Tire Constraints: The Hummer’s off-road tires hampered traction versus the Rivian’s street rubber—a critical factor for owners considering terrain use.
- Thermal Management: Repeated launches triggered power reductions, emphasizing that peak performance requires cooldown periods.
Professional Takeaway: After analyzing the data, I believe the Rivian’s engineering prioritizes efficiency in power delivery. The Hummer’s focus on experiential theatrics (like its Unreal Engine-powered graphics) appeals differently but doesn’t translate to straight-line dominance.
EV Truck Buyer’s Checklist
- Test launch control personally: System responsiveness varies dramatically (e.g., Hummer’s multi-step WTF vs. Rivian’s single-mode).
- Verify real-world range: Aggressive driving slashes EPA estimates by 30-40%.
- Consider tire options: Off-road tires sacrifice 0.5s in 0-60 mph versus street variants.
- Research charging curves: Peak charging speeds drop significantly after 80% state of charge.
- Evaluate software updates: OTA improvements can alter performance (e.g., Rivian’s recent 15-hp boost).
Advanced Resources
- Telemetry Apps: Use Dragy ($150) for instrumented testing—its GPS accuracy outperforms factory systems.
- Forums: Rivian Forums (community-tested efficiency hacks) and Hummer EV Owners (mod discussions).
Why these? Both offer manufacturer techs in discussions, providing insights beyond marketing claims.
Final Verdict
The Rivian R1T’s power-to-weight ratio makes it the quicker truck, but the Hummer EV delivers unmatched theatricality. As Throttle House concluded: "Both prove EVs can be shockingly fun—even at 9,500 pounds."
