Rivian burst onto the scene with the R1T Quad-Motor, an 835-hp supertruck that may deal with gnarly off-road obstacles and match sports activities automobiles to 60 mph. Now there is a extra smart 533-hp Twin-Motor variant, which could be bumped as much as 665 horsepower via a $5000 Efficiency bundle. The R1T Twin-Motor Efficiency is not as excessive because the Quad-Motor, however it retains the identical composed driving demeanor, well-appointed inside, and intelligent packaging, with almost a Corvette Z06’s value of energy nonetheless bringing gut-punch acceleration.
The most cost effective Twin-Motor fashions begin at $74,800, however the Glacier White Efficiency model we examined got here in at $92,850. The Twin-Motor tipped our scales at 6914 kilos, 122 kilos lower than the Quad-Motor. Most of that weight reduction could be attributed to the Twin-Motor having a tire inflation package as a substitute of a full-use spare. The 128.9-kWh “Giant” battery—a $6000 add-on required with the Efficiency pack—gives as much as 352 miles of vary, however the 22-inch wheels—shod in Pirelli Scorpion Zero All Season Elect rubber—on this instance drop the EPA’s ranking to 341 miles. Obtainable all-terrain tires lower vary even additional to 307 miles. Our 75-mph freeway take a look at revealed the Twin-Motor can journey 280 miles on cost—a little bit of a letdown contemplating the Quad-Motor rolling on the identical tires returned an an identical quantity and that the quantity is considerably shy of the Twin-Motor’s EPA estimate.
The separate eco-minded Preserve mode from the Quad-Motor is folded into the Twin-Motor’s All-Function mode, which disconnects the rear motor round 20 mph within the majority of driving situations to spice up effectivity however will reconnect it at low speeds or when extra energy is required.
Sport mode retains the Twin-Motor in all-wheel drive and unlocks the total energy output, with the 2 electrical motors combining for 829 pound-feet of torque, 79 lower than the Quad-Motor. That is sufficient shove for the R1T to leap to 60 mph in 3.4 seconds, placing it 0.4 second behind the Quad-Motor. The quarter-mile flashed by in 12.0 seconds, trailing the Quad-Motor by 0.5-second. The All Season tires helped the Twin-Motor file 0.82 g on the skidpad, the identical because the Quad-Motor carrying an identical rubber. Braking efficiency from 70 mph improved by three ft to 173 ft.
The principle distinction versus the Quad-Motor is how the torque is dished out. As a substitute of exact torque supply to particular person wheels, the Twin-Motor splits the output throughout the entrance and rear axles. From there, brake-based torque vectoring routes the torque to the wheel with essentially the most traction. This reduces the R1T’s capability off-road, the place the four-wheel vectoring is vital for sniffing out each final little bit of traction. In day by day driving, you will not discover the distinction, with the entrance/rear system nonetheless protecting the truck balanced when zipping down a two-lane street.
The Twin-Motor is in any other case an identical to extra highly effective R1Ts, with glorious physique management and correct steering. The experience can really feel jittery on bumpy roads at decrease speeds, however on the transfer, the air-spring suspension is well-damped. This R1T emitted some loud thuds over damaged pavement round city and a slight clunk from the rear when the motor disconnects. The R1T’s whisper-quite operation—recording simply 68 decibels at 70 mph—may need made these noises extra obvious.
The cabin stays a nice place to be—stuffed with rich-feeling fake leather-based and open-pore wooden—even when too many capabilities are buried within the display screen. The Twin-Motor additionally stays a sensible alternative with the sizable frunk and nifty gear tunnel with 12 cubic ft of house.
The R1T Twin-Motor Efficiency is an expensive proposition however gives almost all the similar mind-bending on-road functionality. Should you do not care about successful stoplight drag races, skipping the Efficiency pack will save $5000 whereas nonetheless sprinting to 60 mph in a Rivian-estimated 4.5 seconds. So, you possibly can skip the Quad with out a lot lack of muscle.
