IAA Mobility 2021: BMW To Showcase The iX5 Hydrogen

The BMW Group is systematically pushing forward with development of hydrogen fuel cell technology as an additional option for sustainable individual mobility. Two years after unveiling the BMW i Hydrogen NEXT concept car, the company will present the BMW iX5 Hydrogen at the IAA Mobility 2021 in Munich. Currently still in series development, the SUV with hydrogen fuel cell drive train will be one of several vehicles visitors can experience as they are driven along the Blue Lane connecting the main exhibition grounds with other exhibition venues in the city centre.

A small series of the BMW iX5 Hydrogen, developed on the basis of the BMW X5, will be used for demonstration and testing purposes from the end of next year. Its hydrogen fuel cell system is further proof of the BMW Group's leading development expertise in the field of electric drive technologies.

Individual exterior and interior design elements highlight the car's ties to the BMW i brand, as well as its specific drive technology. The inner edging of the BMW kidney grille, the inserts in the 22- inch aerodynamic wheels and the attachments in the outer portion of the rear apron are all in BMW i Blue. The entry sills and cover trim for the instrument panel also sport a "hydrogen fuel cell" badge.

The mesh inserts covering the cooling air openings at the front of the BMW iX5 Hydrogen, as well as the rear apron and its diffuser element, also have their own unique design. The ornamental grilles covering the BMW kidney grille, the lower and two outer air inlets and the body elements for the lower rear end trim are all made using 3D printing.

The BMW iX5 Hydrogen's aerodynamic wheels come with sustainably produced tyres made of natural rubber and rayon. The raw materials for this are extracted in compliance with the standards of the independent Forest Stewardship Council (FSC) organisation. The BMW Group is the first automotive manufacturer worldwide to use Pirelli tyres made exclusively from certified natural rubber and the wood-based material rayon in its production vehicles.

The BMW iX5 Hydrogen combines fuel cell technology with a fifth-generation BMW eDrive. The drive system uses hydrogen as fuel by converting it into electricity in a fuel cell - delivering an electrical output of up to 125 kW/170 hp, with water vapour as the only emission. This drive power also enables it to maintain consistently high speeds over longer distances. The electric motor was developed from the fifth-generation BMW eDrive technology also used in the BMW iX. In coasting overrun and braking phases, it serves as a generator, feeding energy into a power battery. The energy stored in this power battery is also utilised for particularly sporty driving manoeuvres - delivering a system output of 369 bhp.

The hydrogen needed to supply the fuel cell is stored in two 700-bar tanks made of carbon-fibre reinforced plastic (CFRP), which together hold almost six kilograms of hydrogen. Filling up the hydrogen tanks only takes three to four minutes.
