Polaris has unveiled a novel improvement to its continuously variable transmission (CVT) on the 2027 Xpedition side-by-side utility vehicle. By integrating a pneumatic system alongside the established mechanical CVT, the new design promises a quieter, smoother ride and better fuel economy when the vehicle is cruising or crawling at low RPM.
- Pneumatic system reduces CVT noise by 40% at cruising speed
- Three driver modes allow control of noise and performance
- Compressor also enables onboard tire inflation via a built-in air nozzle
What happened
Polaris has upgraded the transmission system in its 2027 Xpedition utility vehicle by adding a pneumatic-assisted continuously variable transmission (CVT). This enhancement pairs a traditional mechanical CVT with an air compressor, an air tank, and a pneumatic piston to soften the harshness and noise when maximum engine speed isn’t required. The drivetrain remains fully functional in pure mechanical mode if pneumatics malfunction.
The pneumatic piston controls the drive clutch’s compression with compressed air, lowering engine RPM during low-effort driving like cruising or slow crawling. In doing so, the system cuts down engine noise and improves fuel economy. Drivers can switch between Comfort, Standard, and Sport modes to optimize for quietness or power depending on the trail and riding conditions.
Why it feels good
The most noticeable advantage of the pneumatic CVT system is the significant reduction in noise, making the ride more pleasant and less fatiguing. In Comfort mode, noise levels drop by about 9 decibels—roughly a 40% decrease—compared to traditional mechanical systems at 35 mph, allowing passengers to hold conversations comfortably within the cabin.
Beyond noise reduction, the system’s ability to lower RPM during gentle driving improves fuel efficiency, extending the vehicle’s range on trails. The seamless integration of pneumatics with the familiar mechanical layout provides a smooth transition between quiet cruising and powerful output without risking reliability, contributing to a confident and enjoyable off-road experience.
What to enjoy or watch next
Alongside quieter operation, the onboard air compressor offers practical benefits. It includes its own filtered air intake and a compact high-output design that can inflate tires via an integrated air nozzle located behind an easy-access panel on the vehicle’s rear fender. This addition supports quick adjustments on the trail, such as inflating tires from a previously aired-down state.
This innovation signals a broader shift in side-by-side vehicles toward more refined, convenient features that meet the demands of trail enthusiasts. Watching Polaris’s ongoing evolution in blending mechanical reliability with smart technology hints at future utility vehicles that will further blend comfort, efficiency, and off-road capability.
