Abstract
The V12 engine of world's first hydrogen-powered luxury saloon car, which was created in a series development process, represents a further landmark along the road to the hydrogen age. Thanks to sequential hydrogen injection, combined with Valvetronic and a complex operating strategy, the 6.0 l engine develops 390 Nm of torque and a power output of 260 bhp. At the same time it clearly undercuts the toughest emissions regulation worldwide.
