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 (37.3 mph) 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 LMX will take to the streets this summer. The base price in Germany is €210,000. The Audi R8 (14,9 – 12,4 l/100 km [15.8 – 19.0 US mpg]; 349 – 289 g CO2 per km [561.7 – 465.1 g/mile]) 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 419 kW (570 hp) and 540 Nm (398.3 lb-ft) of torque, its 5.2 liter, V10 engine accelerates the car from 0 to 100 km/h (62.1 mph) in just 3.4 seconds. Top speed is 320 km/h (198.8 mph), and average consumption is 12.9 liters of fuel per 100 kilometers (299 grams CO2 per kilometer) [18.2 US mpg/481.2 g/mile]. 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 (15.0 in) 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.
