Last updated August 4, 2026

Buick Cascada

The Buick Cascada lineup starts with the 1SV, a well-equipped four-seat convertible with a power soft top, heated leather-appointed front seats, navigation, and a 200-hp turbo engine. Premium adds parking help, driver alerts, and weather-friendly conveniences for easier touring. Sport Touring keeps the added alerts and parking support but stands apart with distinctive wheels and sportier cabin details.

Frequently asked questions

What are the Buick Cascada trim levels?

The main trim order is 1SV, Premium, and Sport Touring. The 1SV and Premium ran throughout the U.S. model’s life. Sport Touring joined for 2017 and continued through the final 2019 model year.

Is the Cascada 1SV the base trim?

Yes. The 1SV is the entry trim, but it still has the Cascada’s core equipment: the 200-hp turbo engine, insulated power roof, heated power-adjustable front seats, leather-appointed seating, and a heated steering wheel.

What does the Cascada Premium add over the 1SV?

Premium mainly adds convenience and warning features. It brings front and rear parking sensors, forward collision alert, lane departure warning, rain-sensing wipers, and wind-reducing air deflectors without changing the engine.

What's the difference between Cascada Premium and Sport Touring?

Sport Touring is mostly a styling step from Premium. On 2017–2019 models, it adds distinctive 20-inch wheels, a flat-bottom steering wheel, alloy pedals, and darker cabin trim while retaining the parking support and driver warnings found on Premium.

Is the Cascada Sport Touring faster than the other trims?

No. Sport Touring uses the same 200-hp 1.6-liter turbo engine, six-speed automatic, and front-wheel-drive layout as the other trims. Its sport theme comes from the wheels, steering wheel, pedals, and cabin details rather than extra performance.

Which Cascada trim has forward collision and lane departure warnings?

Premium has both forward collision alert and lane departure warning throughout the U.S. run. Sport Touring also has them on 2017–2019 models. The 1SV does not include these warning systems.

Which Cascada trim is easiest to park?

Premium and Sport Touring are the better fits for parking help because they have front and rear parking sensors. The 1SV leaves out that extra assistance.

Which Cascada trim should I pick for the core convertible experience?

The 1SV covers the essentials. It has the same turbo engine and insulated power soft top as the higher trims, plus heated leather-appointed front seating and a heated steering wheel. Move up mainly for added warnings, parking help, or sport-themed details.

Which Cascada trim is the better fit for relaxed road trips?

Premium is the comfort-focused pick. Its wind-reducing air deflectors, rain-sensing wipers, parking sensors, and driver warnings add convenience while keeping the same relaxed turbo powertrain and insulated roof as the 1SV.

Which Cascada trim has the sportiest look?

Sport Touring has the sportiest presentation on 2017–2019 models. Its identifying details are 20-inch twin-spoke wheels, a flat-bottom leather-wrapped steering wheel, alloy sport pedals, and black interior trim.

Do all Cascada trims have heated leather seats?

Yes. Every trim has heated, power-adjustable front seats with heat-reflective leather-appointed upholstery. That includes the 1SV, Premium, and 2017–2019 Sport Touring.

Do all Cascada trims have built-in navigation?

Built-in navigation is standard across all trims on 2018–2019 Cascadas through the 7-inch touchscreen. It was not a lineup-wide standard feature before 2018, so check the equipment on an earlier used example.

Do Cascada trims use different engines?

No. Every U.S.-market Cascada trim uses the same 200-hp 1.6-liter turbo four-cylinder engine and six-speed automatic transmission. Moving up the trim ladder changes comfort, warning, parking, and appearance features instead of power.
