Rivian gave its dual-motor models a lot more go when it introduced the $5,000 Performance Pack. The package ups power from 533 horsepower to 665 hp, with an impressive 219 pound-feet torque gain for a maximum output of 829 lb-ft. It shaves eight-tenths off the 0 to 60 mph sprint time, which falls to 3.5 seconds, and almost one second off its quarter-mile time. But so far it’s only been available as an option when you configure a new truck.
