Polaris Slingshot Sl
The Polaris Slingshot Sl has a top speed of 201 km/h (125 mph — estimated, Polaris does not officially publish a top speed), produces 173 hp and weighs 794 kg. Motoryk rates it 7/10.
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.

Used Buyer Review
"A genuinely fun weekend toy, but buy with eyes wide open."
$15,000-$28,000 usedLet's get this out of the way first — the Slingshot is not a motorcycle. Polaris calls it an autocycle, and that matters when you're buying used because licensing requirements, insurance, and registration vary wildly by state. That said, it's an absolute riot to drive. The 2.4-liter Ecotec engine pulls hard, the open-air experience is genuinely thrilling, and heads will turn everywhere you go. For the right buyer, it's an experience nothing else quite replicates. On used examples, check the clutch carefully on manual models — they get abused by riders who've never driven stick. The 2020+ refresh with the ProStar 2.0 engine is noticeably better than earlier Ecotec-powered units, so prioritize those. Body panels crack easily and they're expensive to replace, so inspect every panel closely. Electronics can be finicky — test every screen and feature before signing anything. Maintenance costs are higher than most expect, parts availability can be spotty, and resale holds surprisingly well — meaning sellers rarely give these away cheap.
