High range, swift refueling, sporty road performance: The Audi h‑tron quattro concept car can boast all these virtues. It combines a highly efficient fuel cell achieving an output of up to 110 kW with a powerful battery that can provide a temporary boost of 100 kW. The car can be fully refueled with hydrogen in around four minutes, and is then ready to drive for up to 600 kilometers (372.8 mi).

The 2.0 TFSI with a displacement of 1,984 cc is available in the new the Audi A4 ultra and A4 Avant ultra. Its technical refinements are the exhaust manifold integrated into the cylinder head, the rotary-valve model for thermal management, the Audi valve-lift system (AVS) for the intake valves, the electric wastegate of the turbocharger and the dual fuel injection. In partial load, indirect injection in the inlet manifold supplements the FSI direct injection. ection.

37 light-emitting diodes in each of the headlights of the new R8 Spyder produce a bright LED light that can be augmented with the optional Audi laser light. A module with four high-power laser diodes, each of which is just 300 micrometers in diameter, emit a blue laser beam with a wavelength of 450 nanometers. A phosphor converter converts it into white light with a color temperature of 5,500 Kelvin, which is pleasant to the human eye.
