Polaris Slingshot: A Decade of Thrills

The Genesis and Evolution of the Polaris Slingshot

Since its groundbreaking introduction in 2015, the Polaris Slingshot has carved a unique niche in the automotive world, offering an exhilarating open-air driving experience that blurs the lines between car and motorcycle. This three-wheeled marvel has undergone a significant evolution over the years, with Polaris consistently refining its design, performance, and features to cater to an ever-growing enthusiast base. This article delves into the journey of the Slingshot, tracing its development from its inaugural year through to the latest iterations, highlighting key changes and innovations along the way.

The Inaugural Year: 2015

The year 2015 marked the very first production run of the Polaris Slingshot. It arrived with three distinct trim levels, each offering a different flavour of the Slingshot experience:

• Base: This entry-level model was designed for purists, foregoing a windshield and stereo system to keep the focus squarely on the raw driving sensation. It featured 17x7 front wheels with a +42mm offset, shod in Kenda 205/50R17 tyres, and 18x9.5 rear wheels with a +45mm offset, fitted with Kenda 265/35R18 tyres.
• SL: Stepping up, the SL trim added creature comforts such as a windshield and a stereo system. The wheel and tyre specifications were upgraded to 18x7.5 front wheels with a +42mm offset and Kenda 225/45R18 tyres, and 20x9 rear wheels with a +45mm offset, wearing Kenda 255/35R20 tyres.
• SL LE (Limited Edition): Differentiating itself with a striking Nuclear Sunset Orange paint scheme, the SL LE also included the windshield and stereo. Its wheel and tyre specifications mirrored those of the SL model.

Refinements and New Colours: 2016 & 2016.5

The 2016 model year saw minor but notable tweaks. While the core specifications remained largely consistent, the SL LE was offered in a new Black Pearl paint option. Furthermore, a limited run saw the frame, control arms, and swing arm powder-coated in a vibrant red, adding a splash of performance-oriented aesthetics. The '2016.5' designation indicated a mid-year update, primarily featuring colour changes, with the SL LE available in two colour choices. Crucially, the wheel and tyre specifications remained unchanged across all models during this period.

Interior Upgrades and the SLR Debut: 2017

2017 brought a wave of enhancements, including new paint colours, updated sticker packages, and significant interior improvements. The base and SL models received upgraded 'Velocity Street Seats', offering enhanced comfort and superior thigh and lateral support compared to the previous hollow rubber seats. This year also saw the introduction of the 'Ride Command' system, featuring Rockford Fosgate speakers, a larger LCD touchscreen radio, a vehicle information centre, and turn-by-turn navigation. While standard on the new SLR model, this advanced infotainment was an optional upgrade for the SL. The year also witnessed the launch of the SLR model, which boasted even more supportive 'Velocity Street Sport' seats and distinctive two-tone paint schemes. The SLR also featured different wheel and tyre sizes: 18x7.5 front wheels with a +42mm offset and Kenda 225/45R18 tyres, and a wider 20x11 rear wheel with a +45mm offset, fitted with Kenda 305/30R20 tyres.

Model Rebranding and New Additions: 2018

Polaris continued to evolve the Slingshot lineup in 2018. The SL LE was rebranded as the 'SL Icon', offering the same specifications as the SL but with four additional colour schemes alongside the standard red and navy options. A significant new addition was the 'GT LE' (Grand Touring Limited Edition). This model shared the two-tone paint of the SLR but introduced the innovative 'Slingshade' roof system with gullwing doors for improved entry and exit. The GT LE also adopted the wheel and tyre specifications of the standard SL model. The SLR remained largely unchanged, though an 'SLR LE' variant was introduced, offering an additional two-tone colour option. Wheel and tyre specifications for other models remained consistent.

Icon Series and Colour Options: 2019

In 2019, the SLR LE was phased out and replaced by the 'SLR Icon'. This change primarily meant an expanded colour palette for the SLR, now offering a total of five colour choices. The SL Icon models saw a reduction in additional colour options, from four in 2018 to three, aligning with the SLR Icon's colour choices. A key differentiator between the SL Icon and SLR Icon remained the SLR's distinctive two-tone paint on the hood and the 'SLR' badging on the rear fin, contrasting with the SL's 'SL' badging. Wheel and tyre specifications across the range stayed the same.

Powertrain Revolution and Design Facelift: 2020

The 2020 model year marked a pivotal moment for the Slingshot. Polaris replaced the GM 2.4L Ecotec engine with its proprietary 'Prostar 2.0L' naturally aspirated engine, capable of revving to 8500rpm. This year also introduced the first factory-option automatic transmission, dubbed 'AutoDrive'. The 'S' model was discontinued, with the lineup consisting of the SL, the new 'R' model, and the GT LE. Both the exterior and interior received a substantial facelift. Externally, new headlights integrated the high and low beams into a single centre-mounted unit, and new gap fillers were added around the daytime running lights. The roll hoops were also redesigned. Internally, the cockpit saw a significant upgrade: cup holders were repositioned for better accessibility, the gauge cluster was updated with a sleek new unit featuring an LCD screen, and the infotainment system was enhanced to a 7-inch touchscreen display with Ride Command features, navigation, and a backup camera. The display was oriented vertically to combat sun glare. The steering wheel also gained buttons for controlling driving modes and the infotainment system. The S and SL models featured 18x7.5 front wheels with a +42 offset and Kenda 225/45R18 tyres. The SL and GT LE models had 20x9 rear wheels with a +45 offset and Kenda 255/35R20 tyres. The R model shared the same front wheel and tyre specifications but sported a wider 20x11 rear wheel with a +45 offset, fitted with Kenda 305/30R20 tyres.

Model specifics for 2020:

• SL: With 178hp, the 2020 SL was exclusively offered with the AutoDrive transmission and came in Red Pearl or Blue Steel paint.
• R: The 203hp 2020 R was available with either a manual or AutoDrive transmission and could be had in Stealth Black or Miami Blue paint.

Further Enhancements and Model Lineup Adjustments: 2021

For 2021, Polaris reintroduced the 'S' model, now featuring roll hoops reminiscent of classic Shelby Cobras. The SL and R models continued, joined by the new 'R LE'. The GT LE was removed from the lineup. The Ride Command system received an update, incorporating Apple CarPlay, and paddle shifters were added to the AutoDrive models (though these were also available as an upgrade for 2020 models). The S and SL models retained the 18x7.5 front wheels with a +42 offset and Kenda 225/45R18 tyres, and 20x9 rear wheels with a +45 offset and Kenda 255/35R20 tyres. The R and R LE models shared the same front wheel and tyre specifications but featured the wider 20x11 rear wheel with a +45 offset and Kenda 305/30R20 tyres.

The Latest Iterations: 2022

The 2022 model year saw further refinements and a clear segmentation of the Slingshot offerings:

• S: Positioned as the ultimate canvas for customization, the S model provides the essential Slingshot experience. It was available in Ghost Gray.
• SL: Aimed at those seeking enhanced style and premium finishes, the SL model includes a Rockford Fosgate 100w audio system. Available colours included Red Pearl, Ultra Blue, Moonlight Metallic White, Volt Orange, Miami Blue, and Liquid Lime.
• SLR: This performance-oriented trim boasted a two-tone paint scheme with gloss and matte finishes, premium sport seats for enhanced cornering support, and the 203 horsepower engine. The SLR was offered in Forged Orange and Forged Red.
• R: The top-tier R model featured bold paint schemes, paddle shifters (for AutoDrive), enhanced styling, and the Technology Package 3, which included turn-by-turn navigation and connected services. Available colours were Pacific Teal Fade, Midnight Storm Fade, Liquid Lime Fade, and Voltage Orange Fade.
• LE (Limited Edition): The Signature LE represented the pinnacle of Slingshot design and technology for its release year. It featured a limited-edition Tri-Tone paint scheme, a new Vented Sport Hood, updated wheel designs, a 7-inch display powered by RIDE COMMAND, GPS navigation, RIDE COMMAND+, stage 3 Rockford Fosgate audio, and Apple CarPlay. The LE was exclusively offered in Crimson Forge.
