2021 Polaris Slingshot R Review | Making a case for the manual

We like quirky vehicles that don’t fit into established segments, like the Polaris Slingshot. It’s certainly no surprise, then, that after spending a couple of weeks with a 2021 Slingshot equipped with a proper shift lever and clutch pedal, we walked away secure in the knowledge that the five-speed manual transmission is the way to go for the ultimate three-wheeled experience. The base engine produces 120 pound-feet of torque while the upgraded version kicks out 144 lb-ft. With a curb weight of just 1,653 pounds (1,667 with the automatic), the power-to-weight ratio of 8.1 lb/hp pushes the Slingshot R to 60 miles per hour in just 4.9 seconds.
