Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2026 Z4.
The 2026 BMW Z4 is a two-seat convertible sports car built on a rear-wheel-drive platform, paired with a smooth-shifting eight-speed automatic transmission and delivering EPA-estimated fuel economy of 23 mpg in the city, 29 mpg on the highway, and 25 mpg combined, placing it squarely in the competitive landscape of its segment; this model year arrives with an exceptional reliability profile, as the nameplate has reached its lowest complaint level in over two decades—just one owner complaint recorded in 2022 compared to 414 in 2003—while currently showing zero open recalls, suggesting meaningful improvements in build quality and customer satisfaction over the Z4's 2002-2023 model history.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The provided federal record does not include a 2026 row in its year-by-year table, so direct comparison of total complaints, recalls, investigations, and TSBs against adjacent years is not possible from this dataset. What the target-year fields do show is minimal activity: one top complaint area listed as “Steering, Power Train, Service Brakes” with a count of 1, and zero crash or fire complaints. Against the modern-year sequence in the record, the trajectory from 2019 through 2023 is downward on every measure—complaints fell from 5 to 0, recalls from 6 to 2, and TSBs from 242 to 36—so the 2026 indicators appear consistent with the low-complaint tail end of that arc. Because the full 2026 counts are absent, we cannot confirm whether recalls and TSBs also stayed low, but the available data place it in the quieter portion of the trend. The data does not specify a root cause for the single reported complaint, so no underlying defect can be inferred. Bottom line: based only on the numbers given, the 2026 Z4 looks like a low-risk year with no reported fire or crash complaints, making it a reasonable used-buy candidate provided a pre-purchase inspection checks the steering, powertrain, and brake systems referenced in the lone complaint.
