Eric's Autos: 2018 Buick Cascada
You can drop the top without having to stop.
There are usable back seats with 32.8 inches of legroom, and there's a large trunk (13.4 cubic feet).
It's very reasonably priced compared with rivals like the Audi A3 cabriolet.
What's Not So Good
It has mediocre acceleration, and there's no optional engine to fix that.
Even though it's only 2 years old, it still has some old-timey equipment -- like a physical ignition key instead of a keyless/push-button ignition.
Under the Hood
In keeping up with trends, the Cascada has a very small (just 1.6 liters) four-cylinder engine with a turbo bolted to it for on-demand power. It has 200 horsepower -- strong for its size. But the Cascada is a heavy car, at 3,979 pounds, which is why this drop-top Buick needs 8.6 seconds to achieve 60 mph. This is much slower than the Audi A3 cabriolet, which can get to 60 almost 3 seconds sooner with its optional 220-horsepower engine. As mentioned previously, the Buick doesn't offer an optional engine.
Gas mileage is so-so, coming in at 20 mpg city and 27 highway. The more powerful -- and much quicker -- A3 cabriolet manages 35 mpg on the highway.
On the plus side, the Buick's turbocharged engine is designed to run on regular 87-octane unleaded gas. The Audi's turbocharged engine requires premium.
