Audi launches production car with laser high beams
Neckarsulm, May 11, 2014
German automaker Audi has launched a new limited edition car, the first production car in the world to come equipped with laser high beams.
The combination of LED and laser high beams will be used for the first time on the new Audi R18 e tron quattro at the 24 Hours of Le Mans on June 14 and 15.
“Audi has long dominated the most important 24-hour race. In addition to the outstanding TDI drive technology, a maximum light yield gives our pilots a major advantage, and with night racing in particular is a key factor to our success,” said Prof Dr Ulrich Hackenberg.
“The transfer of the laser headlight to the Audi R8 LMX underscores our leading position in lighting technology. The safety benefit this provides to the customer truly represents Vorsprung durch Technik.”
With the new laser high beams, one laser module per headlight generates a cone of light with twice the range of the all LED headlight. Each module comprises four high power laser diodes.
With a diameter of just 300 micrometers, these generate a blue laser beam with a wavelength of 450 nanometers. A phosphor converter transforms this into roadworthy white light with a color temperature of 5,500 Kelvin – ideal conditions for the human eye that enable the driver to recognize contrast more easily and help prevent fatigue.
The laser spot, which is active at speeds of 60 km/h and above, supplements the LED high beam in the R8 LMX and greatly enhances visibility and safety. An intelligent camera based sensor system detects other road users and actively adjusts the light pattern to exclude them.
The Audi R8 is the dynamic, top of the line Audi model. Its high-revving, mid mounted engine, double wishbone suspension and ASF (Audi Space Frame) aluminum body are closely based on racing. The Audi R8 LMX is available as a coupe with a production run limited to 99 vehicles. With 570 hp and 540 Nm of torque, its 5.2 liter, V10 engine accelerates the car from 0 to 100 km/h in just 3.4 seconds. Top speed is 320 km/h, and average consumption is 12.9 liters of fuel per 100 kilometers (299 grams CO2 per kilometer).
A compact, seven speed S tronic transfers the power to the quattro permanent all-wheel drive system. 19-inch wheels are combined with carbon fiber ceramic brake discs, which up front measure 380 millimeters in diameter. Red anodized brake calipers shine behind the exclusive designer wheels. The R8 LMX is shod with 235/35 R 19 tires up front and 305/30 R 19 tires at the rear.
The Audi R8 LMX will take to the streets this summer. The base price in Germany is approximately 210,000 euros ($288,900). – TradeArabia News Service
