Figures in [ ] apply to models with five-speed automatic transmission.
1: Top speed limited electronically.
2: BMW test results. Actual acceleration results may vary, depending on specification of vehicle, road and environmental conditions, testing procedures, and driving style. These results should be used for comparison only and verification should not be attempted on public roads. BMW urges you to obey all posted speed laws and always wear safety belts.
3: EPA-estimated figures are for comparison purposes only. Your actual mileage will vary, depending on speed, driving habits, trip length, and driving conditions; actual mileage may be lower.
4: Z4 Roadsters with run-flat tires are not equipped with a spare tire and wheel.
5: Due to low-profile tires, please note: wheels, tires and suspension parts are more susceptible to road hazard and consequential damages. Performance tires are not recommended for driving in snow and ice conditions.
