Audi going to full LED lighting on the R8 for just $5,600



In the ongoing effort to improve fuel efficiency on vehicles, automakers are looking for ways to reduce parasitic losses that absorb power from the engine rather than sending it to the drive wheels. That means replacing constant drive hydraulic steering assist systems with on-demand electric equivalents and just generally trying to cut the power requirements for all accessory systems. One area that draws power is the lighting system. Cutting the power requirements for headlights is a tricky problem since performance needs to be maintained for safety reasons. One of the best new technologies for lighting is LEDs. Last year Lexus launched LED low beam headlamps on the LS600h and now Audi is taking the next step with the R8 sports car.

Audi has just added a new full LED light option that includes high and low beams, turn signals and daytime running lights. The cluster contains 54 LEDs that never wear out, provide better lighting performance and use less power. There is just one problem, as usual with new technology: it's expensive. Audi is charging a €3,590 ($5,600 U.S.) premium for the full LED system. Eventually the price will come down, hopefully sooner rather than later and on a car like the R8 it probably won't make much difference to the mileage. Nonetheless all of these little things add up and help. Going forward as we move to electrified cars, reducing the electrical power draw will be even more critical. By the middle of the next decade when we have significant numbers of electric cars coming to our roads we will probably start seeing LED lighting going mainstream. Details from Audi after the break.
