2021 BMW Z4 Roadster Review: Crackerjack Cruiser

by Aiden Eksteen

Imagine a sports car that's sophisticated enough to show up to business meetings in, proficient enough to dominate in your club's emulous track days, and has enough luxury to make cruising around a dream experience. Well, imagine no more, as the 2021 BMW Z4 Roadster is this car, comprising a sporty yet authoritative demeanor, two dynamite and refined engines, and all the contemporary creature comforts, conveniences and safety features one would expect from a premium vehicle. In the focused Z4 line is the sDrive30i, which comes standard-fit with a 255-horsepower 2.0-liter inline-4 turbo engine, while the sDrive M40i gets a 382-hp 3.0-liter turbo 6-cylinder motor. The 2021 Z4 Roadster has the dynamic performance chops to put it up against the likes of the Porsche 718 Boxster and the modern and luxurious makeup to stand alongside the tech-laden Audi TT.

Verdict: ๐ŸIs the 2021 BMW Z4 Roadster a good convertible?

There are still a multitude of premium 2-door roadsters in the USA that are stunning, capable, and contemporary, despite the current SUV and crossover trend. That means the Z4 Roadster convertible has a lot of competition, including the renowned Porsche 718 Boxster. However, none have the proud legacy of the BMW Roadster, making it one of a kind within the segment. It's an eye-catching drop-top, too, and contemporary both outside and in. Each of the engines in the line offer plenty of power and throttle responses are precise and refined. Together with the Z4's masterfully modulated chassis and racing-traditional RWD setup, this delivers a truly phenomenal driving experience. It comes fairly well-outfitted with modern and luxurious creature comforts and conveniences, but at the 2021 BMW Z4 Roadster's price of $49,700, we feel it could be presented with a few more driver assists. After all, the current fourth-gen Z4, which includes the 2021 BMW Z4 Roadster, hasn't undergone review for its crashworthiness. Most high-end cars don't get a safety rating, though and the Z4 drop-top actually has a pretty decent reliability expectation for a luxury convertible. The Z4 Roadster is undoubtedly a special car and while it may not be the nonpareil of its class, it isn't easily outclassed.
