In the ever-evolving electric vehicle market, Rivian’s R2 Performance is making waves by matching the energy consumption of the 2026 Tesla Model Y Performance while offering a longer driving range. These advancements showcase Rivian’s commitment to innovation in the EV sector.
Equipped with 21-inch all-season wheels, the R2 Performance achieves a commendable 105 MPGe combined, with separate ratings of 114 MPGe for city and 96 MPGe for highway driving, and uses 32 kWh per 100 miles. The US Department of Energy and the Environmental Protection Agency have confirmed its range at 330 miles.
On the other hand, Tesla’s Model Y Performance shares the same efficiency metrics—105 MPGe and 32 kWh per 100 miles—but its range is slightly less at 306 miles.
The Weight and Aerodynamics Gap
Despite the Rivian R2 Performance being heavier and having a bulkier design, it surpasses the Model Y in range. The R2’s curb weight is documented at 4,998 pounds, compared to the Model Y’s 4,466 pounds, marking a difference of over 530 pounds.
The aerodynamic profile further differentiates these vehicles. The Model Y boasts a drag coefficient of 0.22, thanks to its streamlined design. In contrast, Rivian’s R2 is estimated to have a drag coefficient between 0.28 and 0.29, with a boxier shape that increases its frontal area.
Rivian’s Charging
Under the hood, the R2 Performance is powered by two AC permanent magnet motors, delivering a combined 489 kW (approximately 656 horsepower). The battery offers 87.9 kWh of usable energy, with tests recording 88.67 kWh during depletion. The efficiency is enhanced by a redesigned heat pump system, which is standard across all R2 trims.
Rivian’s CEO RJ Scaringe explained that the R2 adopts an “energy cell centric approach” to prioritize range over charging speed. The vehicle supports DC fast charging up to 210 kW, achieving a 10-to-80 percent charge in 29 minutes. Additionally, a native NACS charging port allows access to Tesla’s Supercharger network.
Pricing for the R2 Performance starts at $57,990, excluding destination charges. The Launch Package includes a lifetime Autonomy+ subscription, exclusive paint options, and a tow package rated for 4,400 pounds.
The All-Terrain Tire Penalty
Opting for 20-inch all-terrain tires affects the R2’s efficiency, resulting in a combined 99 MPGe (109 city, 89 highway) and 34 kWh per 100 miles, with the range dropping to 307 miles. This configuration increases the annual fuel cost estimate to $750, and the curb weight rises slightly to 5,016 pounds. Despite this, the range on all-terrain tires remains competitive, nearly matching the Model Y Performance.
Lucid Gravity Leads the Group
Both Rivian and Tesla’s models are surpassed by the 2026 Lucid Gravity Touring, which achieves 111 MPGe combined and a range of 337 miles with a 89 kWh battery pack. This vehicle, with a dual-motor configuration, produces up to 560 horsepower.
The Lucid Gravity’s efficiency stems from its aerodynamic design with a drag coefficient of 0.24, supported by advanced drivetrain engineering. Lucid emphasizes efficiency as a core aspect of its brand identity, with VP of Comms Nick Twork stating that energy efficiency is more critical than fast charging.
Lucid’s Drag Coefficiency
The Lucid Gravity’s drag coefficient of 0.24 is slightly higher than the Model Y’s but is balanced by Lucid’s superior drivetrain. The upcoming Lucid Cosmos aims to set a new standard with a drag coefficient below 0.22 and will utilize the new 800-volt Atlas drive unit. It is anticipated to start under $50,000, with production planned at the Saudi Arabia plant.
