Technical data for the BMW Z4 M40i Roadster.
BMW wheels & tyres.
We subject the tyres for our vehicles to stringent tests with up to 50 different quality criteria – significantly more than prescribed by the uniform tyre labelling regulation that applies throughout Europe. This is where you will find all the information on the properties of the tyres used at BMW.
Consumption and CO2 emissions.
{model.description}: Energy consumption, combined WLTP in l/100 miles: {techdata.consumptionWltpCombined}; CO2 emissions, combined WLTP in g/km: {techdata.emissionsWltpCombined}
The stated values are based on the mandatory WLTP measurement procedure. The real life values depend on various factors, e.g. cargo weight, driving style, route, weather conditions, auxiliary electrical consumption (including air conditioning), tires, battery state of health.
