The Rivian R1T and Rivian R1S were both shown at the LA Auto Show in November, both claiming a top of the line range of 400 miles. The folks over at Rivian Forums have uncovered a patent filing for an extended battery for the Rivian R1T.
The drawing shows a bed mounted battery with connections for coolant and electrical flow. In addition to providing more energy, the R1T would detect when the auxiliary battery was installed and adjust braking, suspension, and steering to compensate for the extra weight.
Rivian uses a skateboard style architecture which places the entire powertrain and battery system in a platform below the vehicle and then builds the body on top of it. This allows Rivian to have nearly a free hand in designing the body and interior above the powertrain.
Rivian will offer 3 standard battery packs for the R1T:
- 105-kWh: 402 horsepower, and 413 lb-ft of torque, range of 230+ miles
- 135-kWh: 754 horsepower, and 826 lb-ft of torque, range of 300+ miles
- 180-kWh: 700 horsepower, and 826 lb-ft of torque, range of 400+ miles
Rivian claims the R1T will get 80 percent charge in just 15 minutes when using a DC fast charger and a full charge in eight hours using a Level 2 charger.
Rivian says the R1T will begin at $61,500 after Federal Tax credit - likely putting the base at just under $70,000. Production is expected to begin in late 2020 at a plant in Normal, Illinois. The company recently landed $700M in investment commitments, lead by a significant investment by Amazon.
