Polaris Slingshot Sl
The Polaris Slingshot was introduced in 2015 as a three-wheeled autocycle, designed to offer an open-air driving experience blending car and motorcycle characteristics. The SL trim level added premium features like an audio system, upgraded interior, and sport-tuned suspension compared to the base model. It is notable for being classified as a motorcycle in most U.S. states, yet features a steering wheel and side-by-side seating, making it a unique niche vehicle that sparked significant interest in the autocycle segment.

What Buyers Should Know
GM Engine Reliability
The SL uses a 2.0L GM Ecotec engine, which is well-proven and widely serviceable at many auto shops — not just Polaris dealers. This makes maintenance costs significantly lower than exotic alternatives.
Watch for Belt Wear
The drive belt is a known wear item and should be inspected regularly, especially on used models. Neglected belts can snap without warning, so always verify replacement history before buying.
Strong Resale Value
Slingshots hold their value unusually well due to limited competition in the 3-wheel autocycle market. The SL trim's added features like audio and upgraded interior make it particularly attractive to resale buyers.
