Fuel Economy Overview

The 2023 BMW Z4 sDrive30i achieves an EPA-estimated 28 MPG in combined city and highway driving, with 25 MPG in the city and 33 MPG on the highway. Powered by a 2L 4-cylinder turbocharged engine paired with a automatic (s8), this two seaters features Rear-Wheel Drive drive.

In terms of environmental impact, the 2023 Z4 sDrive30i produces approximately 312 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this Z4 sDrive30i performs better than the national average in this regard.

The estimated annual fuel cost for this vehicle is $2,450, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $1,500 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.

The weld seam of the integrated transmission control unit's cover may not have been manufactured properly, which could allow automatic transmission oil to leak into the transmission control unit.

Consequence & Remedy

Consequence: Transmission oil that leaks into the control unit can lead to a seizure of the transmission gears, causing a sudden loss of drive power and increasing the risk of a crash.

Remedy: Dealers will replace the transmission mechatronics module and the automatic transmission fluid, as necessary, free of charge. Owner notification letters were mailed January 26, 2024. Owners may contact BMW customer service at 1-800-525-7417.
