HIGH STIFFNESS AND SAFETY: THE CARBON PASSENGER CELL.
BMW i is revolutionising automotive engineering with the first series-produced passenger cells made of carbon - thereby setting new standards in lightweight construction. Thanks to its high strength, the material offers passengers the best possible protection in accidents, yet is still light enough to balance out the additional weight of the HV battery. The result is greater safety combined with a generous and comfortable level of spaciousness which simultaneously saves weight – and thus further increases dynamics.
The BMW i3 and BMW i8 are the first vehicles in which the high-tech material carbon has been used for large-scale series production. For a long time, the use of carbon was limited because it had to be produced manually. Today, the BMW Group produces the carbon fibres and carbon fibre plates itself, which makes large-scale series production possible.
LOW WEIGHT. HIGH ACCELERATION.
From rear axle to aluminium front apron, from the M light alloy wheels to the CFRP roof, the BMW M4 Coupé provides an example of how you can discover the diversity of BMW EfficientLightweight.
BMW M4 Coupé (1):
Fuel consumption in l/100 km (combined): 9.1 (8.3)
CO2 emissions in g/km (combined): 209 (194)
LOW WEIGHT. HIGH ACCELERATION.
Fuel consumption and CO2 emissions.
Figures outside brackets refer to the basic model with transmission as per the basic equipment; figures in brackets to the model with optionally available transmission (see special equipment).
The values of fuel consumptions, CO2 emissions and energy consumptions shown were determined according to the European Regulation (EC) 715/2007 in the version applicable at the time of type approval. The figures refer to a vehicle with basic configuration in Germany and the range shown considers optional equipment and the different size of wheels and tires available on the selected model.
(1) The values are applicable until 15.04.2018. Please check availability with your BMW dealer.
The values of the vehicles labeled with (3), are already based on the new WLTP regulation and are translated back into NEDC-equivalent values in order to ensure the comparison between the vehicles. [With respect to these vehicles, for vehicle related taxes or other duties based (at least inter alia) on CO2-emissions the CO2 values may differ to the values stated here.]
The CO2 efficiency specifications are determined according to Directive 1999/94/EC and the European Regulation in its current version applicable. The values shown are based on the fuel consumption, CO2 values and energy consumptions according to the NEDC cycle for the classification.
For further information about the official fuel consumption and the specific CO2 emission of new passenger cars can be taken out of the „handbook of fuel consumption, the CO2 emission and power consumption of new passenger cars“, which is available at all selling points and at https://www.dat.de/angebote/verlagsprodukte/leitfaden-kraftstoffverbrauch.html.
