2021 BMW Z4 Review, Pricing, and Specs (2024)

Overview

There's nothing better than putting the top down on a nice day and finding an entertaining road to enjoy, and the 2021 BMW Z4 is a great choice for such an activity. Buyers can choose between a turbocharged four-cylinder or a twin-turbo inline-six—the latter of which blasted the Z4 to 60 mph in just 3.8-seconds at our test track. Rear-wheel drive is standard and all-wheel drive isn't offered but, sadly, neither is a manual transmission; all Z4s come with an eight-speed automatic. Dynamically speaking, the Porsche Boxster is still our preferred ragtop sports car but the Z4 offers plenty of driving enjoyment with a slightly smoother ride for day-to-day use. The cabin is snug but comfortable for two adults and has plenty of standard creature comforts and connectivity features. If you'd prefer a fixed-roof coupe, check out the mechanically similar Toyota Supra instead. Toyota collaborated with BMW on it, and the two cars share their powertrains and suspensions.

What's New for 2021?

Few changes are in store for BMW's two-seat convertible for 2021. All models now come standard with SiriusXM satellite radio and Android Auto. Parking sensors have been added to the optional Driving Assistance package and the price has been adjusted up from $500 to $700 accordingly. Other minor changes include the addition of an optional wireless smartphone charging pad and M Sport brakes with red-painted calipers.

Pricing and Which One to Buy

At its base price, the 2021 Z4 Drive30i is an undeniable value. It costs considerably less than its main rival, the Porsche Boxster, and it offers more than enough performance for most buyers. You can also dress it up with the M Sport Kit, which adds an M Sport suspension for better handling and it dials up its appearance inside and out with an aerodynamic body kit and M Sport steering wheel. Larger 19-inch wheels and tires are also available, and BMW offers the Dynamic Handling package, which adds larger M Sport brakes and its M Sport differential for additional traction. Your new Z4 still won't accelerate like the much more powerful M40i, but it'll be more than quick enough to satisfy.

Engine, Transmission, and Performance

Every 2021 BMW Z4 has an eight-speed automatic transmission with Sport mode as well as Manual mode. Paddle shifters mounted to the steering wheel are also standard. That's right: For the first time, the BMW Z4 is not available with a traditional manual transmission with a clutch pedal. You won't miss it. The eight-speed is one of the best automatics around with sharp responses, snappy shifts, and smooth operation. The sDrive30i is powered by the brand's excellent turbocharged 2.0-liter four-cylinder that makes plenty of torque and 255 horsepower. In our testing, this model accelerated to 60 mph in 5.1 seconds. That's quick, but it's a bit slower than a Porsche Boxster, which is still available with a manual gearbox. For more grunt, the M40i model gets a 382-hp twin-turbocharged inline-six. It's incredibly smooth and refined, and it turns the Z4 into a superfast sports car with a zero-to-60-mph time of just 3.8 seconds. That's quicker than the 350-hp Porsche Boxster S.

Fuel Economy and Real-World MPG

With its exceptional performance, it may surprise you that the 2021 BMW Z4 is one of the most fuel-efficient sports cars in its class. The fuel economy of the Z4 sDrive30i is rated by the EPA to be 25 mpg city and 32 mpg on the highway. With its much higher level of horsepower, the fuel economy of the Z4 M40i is just a single mpg lower, getting 24 mpg city and 31 mpg highway. In our testing, both models recorded 20 mpg in mixed driving. Unfortunately, both engines require more expensive premium gasoline, and the Z4 has a small gas tank, so its fuel range isn't extensive. Expect about 300 miles of highway driving between each fill-up.

Interior, Comfort, and Cargo

As is the case with all current BMWs, the 2021 BMW Z4 has a very high-quality interior. In fact, it may have the best interior in this class. It features luxe materials, exceptional panel fitment, and excellent control placement. Its seats are comfortable with sizable bolsters to hold you in place when you're enjoying the Z4's dynamics. There is also more room inside than you might expect, even for those taller than six feet. Thick and insulated, its cloth roof seals tightly. When the top is up, the BMW's interior is impressively quiet, with so little wind or road noise it almost feels like a Grand Touring coupe. With the push of a button, it folds away in a few seconds. A wind blocker is standard to keep wind buffeting to a minimum with the top down, even at high speeds. Interior stowage is also quite generous. There are several storage bins around the Z4's cabin, including one in the center console and a felt-lined cubby to the left of the steering wheel. There's also a netted shelf behind the seats and two big cupholders up front. At 10 cubic feet, the trunk of the Z4 isn't huge, but it'll swallow luggage for two for a quick weekend road trip.

Infotainment and Connectivity

A massive 10.3-inch touchscreen is standard along with navigation and complimentary Apple CarPlay integration; Android Auto capability is not available. The latest iteration of BMW's iDrive system is easy to use, with sharp graphics. The system can also be controlled intuitively with a knob and buttons on the Z4's console or with voice commands. A USB port and Bluetooth streaming audio are also standard, although you have to pay extra for SiriusXM satellite radio. A Wi-Fi hotspot is part of the available Premium package, along with wireless charging for phones, a head-up display, and heated seats.

Safety and Driver-Assistance Features

Forward-collision warning and daytime pedestrian detection with city braking are standard, as is BMW's lane-departure warning system. Other driver-assistance tech is available as options on both Z4 models. That list of available systems includes active cruise control, active blind-spot detection, rear-collision protection, and rear cross-traffic alert. The BMW Z4 has not been crash tested by either the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS), which is common with sports cars. Key safety features include:

• Standard forward-collision detection with pedestrian detection
• Available active cruise control
• Available active blind-spot detection

Warranty and Maintenance Coverage

BMW's warranty is average for the segment; however, its complimentary scheduled maintenance coverage is a standout. Such programs are not offered with its rivals, the Mercedes-Benz SLK-class and Porsche Boxster.

• Limited warranty covers four years or 50,000 miles
• Powertrain warranty covers four years or 50,000 miles
• Complimentary scheduled maintenance is covered for three years or 36,000 miles
