2026 Polaris Slingshot Specs by Trim: S, SL, SLR, R, Signature and Grand Touring

Let's clear up a common mistake first: the Slingshot does not run a "1.5L twin-cylinder, 203 HP" engine. That figure is wrong on every count. Here's what's actually under the hood.

The Engine — What's Actually Under the Hood

Every Slingshot since the 2020 model year runs a ProStar 2.0L inline-four, replacing the earlier GM 2.4L Ecotec used from 2015–2019. No trim runs a twin-cylinder engine, and no trim runs a flat 203 hp — the real numbers vary by trim, below.

180 hp vs. 204 hp — Which Trims Get More Power

S and SL run 180 hp. SLR, R, Signature, and Grand Touring all run 204 hp. Same core engine across the board — the power difference comes from tuning, not a different displacement.

AutoDrive vs. Manual — Transmission by Trim

Every 2026 trim runs AutoDrive — a hydraulically actuated automated 5-speed, not a CVT and not a traditional manual. No trim requires clutch work.

How Much Does a 2026 Polaris Slingshot Cost?

$24,999 to $41,999, pre-destination, depending on trim. That's the buy price — compare it against renting by the hour at $69.99–$149 if you're not sure yet.
