Emissions & certification

|---|---|---|---|---|
| Z4 sDrive30i | 7 / 10 | Federal Tier 3 Bin 30 / California LEV-III SULEV30 | All 50 states (federal, all altitudes); California and states following California standards | — |
| Z4 M40i | 5 / 10 | Federal Tier 3 Bin 70 / California LEV-III ULEV70 | All 50 states (federal, all altitudes); California and states following California standards | — |
Certified for all fifty states, so it can be registered new anywhere in the U.S.
The smog rating scores tailpipe pollutants other than greenhouse gases, 1 (worst) to 10 (best), and is comparable only within a model year. The standard is the federal bin or California tier the configuration was certified to. Both come from the EPA certificate behind the window sticker.

Measured by Transport Canada for its Canadian Vehicle Specifications database, which covers the North American versions of each model — here 2 configurations: M40I 2-door Convertible, sDrive30I 2-door Convertible. Where a range is shown, those versions differ. Width is the body without mirrors, which is why it can read narrower than a brochure figure. Before we used it we checked it against the US manufacturer press kits we hold (27 Sep 2026): wheelbase agreed within 1% on every vehicle we could compare, length on 98%, and the curb weight fell inside the manufacturer's range on 96%.

The cheapest ownership win
Insurers price the 2024 Z4 very differently, and the gap between the best and worst quote on the same car and driver is usually larger than any option you are weighing on this page.

These are vehicle campaigns — the ones the automaker filed against this model. NHTSA also records equipment recalls, filed by a parts maker against a component (a tyre, a child seat, an aftermarket part), and those are not listed here or counted above. nhtsa.gov/recalls shows both for a VIN.
Hear about a recall before the letter does
The manufacturer’s letter is the last step of a recall: it has up to 60 days after filing to mail owners, at the address on the registration. We email you the day NHTSA posts a recall on the 2024 BMW Z4, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

A service bulletin is the manufacturer telling its dealers how to diagnose or repair a known condition. It is not a recall, not a finding that the vehicle is defective, and the work is not automatically free — though a bulletin is often what a dealer works from when you describe a symptom, so quoting the document number can save a diagnosis. The count is every communication filed; the list shows the most recent, one entry per campaign, because a single campaign is usually filed as several documents on the same day. The summaries are NHTSA's; the full documents come from the manufacturer.

How safe is the 2024 BMW Z4?
NHTSA has not published a crash-test rating for the 2024 BMW Z4 yet. On the recall record WhichTrim grades it A (100/100), which measures open and severe recalls rather than crash protection.
What is the fuel economy of the 2024 BMW Z4?
Across the 2 EPA-rated configurations of the 2024 BMW Z4, the best EPA combined figure is 28 mpg. Figures are the EPA's own, per configuration, and every one is listed above.
What are the dimensions of the 2024 BMW Z4?
Transport Canada measured it at 170.9 in long, 73.2 in wide (body, without mirrors), 51.6 in tall, on a 97.2 in wheelbase. Curb weight: 3,296–3,463 lb depending on configuration. Those are its measurements of the North American versions; every figure is in the table above.
What do owners complain about on the 2024 BMW Z4?
Owners have filed 1 complaint with NHTSA about the 2024 BMW Z4, most often about engine. Complaints are unverified owner reports, so treat the pattern as a signal and the individual report as an anecdote.
How clean is the 2024 BMW Z4?
The EPA smog rating for the 2024 BMW Z4 runs 5 to 7 out of 10 across its configurations. That score covers tailpipe pollutants other than greenhouse gases, and it only compares vehicles within the same model year. It is certified for all fifty states, so it can be registered new anywhere in the U.S. Its configurations were certified to different standards — California LEV-III SULEV30, California LEV-III ULEV70, Federal Tier 3 Bin 30, Federal Tier 3 Bin 70 — which the table above lists per configuration.
Are there service bulletins for the 2024 BMW Z4?
The manufacturer has filed 3 service bulletins and related communications with NHTSA for the 2024 BMW Z4, most often covering suspension, engine, seats. The most recent is dated 2026-06-27. A bulletin is not a recall: it is the repair procedure a manufacturer sends its dealers for a condition it knows about, and the work is not automatically paid for. It is still worth knowing — if the symptom matches, quoting the bulletin number at the service desk can save a diagnosis. The document numbers and summaries are listed above.
What we hold, and what an empty row means
Paid vehicle-history reports will not tell you the difference between “nothing happened to this car” and “we never received that record” — both of the big two say as much in their own help pages. Most of what is on this page comes from complete federal registers, so we can tell you which is which, row by row.
| Data | Held | Source | What it covers — or what empty means |
|---|---|---|---|
| Fuel economy & configurations | 2 configurations | EPA certification records | Every configuration the EPA certified for sale, with its own test figures. |
| Emission certificates | 2 configurations | EPA emission certificates | Smog rating, standard and the sales area that decides where the car can be sold new. |
| Recalls | none | NHTSA recall campaigns | No campaign has been filed. Because the register is complete, an empty row here means there is nothing to find — not that we are missing it. |
| Owner complaints | 1 | NHTSA complaint database | Also complete, but unverified: these are reports owners filed, not findings. Counts scale with how many were sold. |
| Crash ratings | none | NHTSA NCAP | NHTSA has not tested this model year. Cars are selected for testing, so untested is not unsafe. |
| Service bulletins | 3 | NHTSA manufacturer communications | Everything the manufacturer told its dealers about a defect or malfunction, short of a recall. |
| Investigations | none | NHTSA Office of Defects Investigation | No defect investigation has been opened. |
| Driver-assist crash reports | none | NHTSA Standing General Order 2021-01 | No report has been filed. Only entities named in the order report, and only crashes they hear of — so this is also what an unequipped car, or a manufacturer without telematics, looks like. |
| Specifications filed with NHTSA | 7 fields | NHTSA vPIC, decoded from VIN patterns | What the manufacturer filed under the federal VIN rule — a configuration, not the full trim ladder. |

Sources & method
Safety Signal starts every model-year at 100 and subtracts points per open NHTSA recall campaign by severity: critical 15 (fire risk, park-outside or do-not-drive advisories), high 8 (brakes, steering, airbags, loss of drive power, structure, battery), moderate 6, minor 3 (software, labels, lighting fixed by an update). The most serious recall counts in full and each further one counts 85% of the one before, because a vehicle sold in millions is recalled more often than a rare one without being more dangerous — and because a flat subtraction bottomed the scale out, scoring a vehicle with 22 recalls within a point of one with six. A ≥ 90, B ≥ 80, C ≥ 70, D ≥ 60, otherwise F. Read it as what it counts: recall campaigns on the federal record, weighted by severity. The damping reduces the sales bias by roughly 40% but does not remove it: like our complaint counts, this is not normalized by how many were sold, so a best-seller still scores somewhat worse than an obscure model with the same real risk. NHTSA crash ratings, do-not-drive and park-outside advisories, and the crash, fire, injury and death counts in owner complaints are reported separately on every page and never blended into the letter — a vehicle can hold five stars and a poor letter at once, and where that happens we say so rather than leave you to notice. Because the scale subtracts from a clean sheet, a model year too new to have been recalled, complained about or bulletined scores full marks on an empty record; we label those grades provisional rather than present them as earned.
