The all-electric Rivian R1T pickup recently received a new Max Pack battery option (149 kilowatt-hours of total capacity), joining the initial Large Pack (about 135 kWh). However, the range increase turned out to be relatively small, especially considering the $10,000 price difference.
The Out of Spec Reviews team recently had an opportunity to range test two basically brand new Rivian R1Ts—one with the Max Pack (the blue one) and one with the Large Pack (the silver one)—in a side-by-side range test at a mostly constant 70 mph speed in slightly cold weather conditions.
