Car and Driver doesn't have specs on the CLS53, but we've heard that it should make around 430 hp.

From the moment electric headlights snuffed out kerosene and acetylene lamps in the 1910s, automakers have struggled to illuminate the road without blinding oncoming drivers. The industry’s first unified effort to rein in glare was led by the carmakers themselves before the automobile was federally regulated. In the span of just two model years, 1940 and 1941, every new car in the United States adopted standardized seven-inch round headlights.

These sealed-beam assemblies, combining the bulb, lens, and reflector into one unit, eventually expanded to include additional sizes and rectangular shapes, but the original seven-incher was still popping up in vehicles such as the 1990–1997 first-generation Mazda MX-5 Miata well after NHTSA had approved replaceable-bulb and nonstandard-shaped headlights in 1983.

2019 Jeep Cherokee reveals a much more normal face

  2019 Jeep Cherokee reveals a much more normal face A handsome if unexciting redesign.The obvious change is the headlights. Instead of the slender daytime running lights at the top next to the grille, and the actual illuminating headlights lower in the bumper, all of the elements are integrated into single housings on either side. They're somewhat rectangular now, looking more like those on the Compass and the Grand Cherokee. But you can still see the same hockey-stick shaped LED running light design in the new lamps. The grille has changed, too. It looks much more blunt than the sharply creased, almost pointy grille of the current model.

Today’s lighting regulations primarily dictate performance, allowing manufacturers to choose from a handful of technologies. High-intensity discharge (HID) lamps produce light with an electric arc in a gas-filled bulb rather than the filament used in conventional halogen bulbs. The latest trends favor energy-efficient light-emitting diodes (LED) and lasers. Both allow for precise control and placement of the beam, to the extent that some “smart” headlights can carve out a dark spot around an oncoming car.

Our test revealed that technology isn’t the only factor in determining headlight performance. NHTSA allows headlights to be located between 22 and 54 inches from the ground yet also calls for a horizontally oriented cutoff to block the beam from angling upward into the eyes of approaching drivers. Mounting the headlights higher, then, is the only way to elevate the beam.

Kia Prices the Stinger GT

  Kia Prices the Stinger GT Kia's first sports sedan now has a price to go with it. The Stinger GT will start at $44,195 for the base GT model, with the GT Limited ringing in at $49,995. Both come with a 3.3L turbocharged V6 that produces 365 hp and 376 lb-ft of torque. They use an eight-speed automatic and send power to all four wheels. The Stinger has a sport-tuned suspension that was developed on Germany's famed Nurburgring race track. The GT comes equipped with a heated steering wheel and seats, and a 7.0-inch touchscreen with Apple CarPlay and Android Auto support. The GT Limited adds niceties like a head-up display, Nappa leather ventilated seats, a 15-speaker stereo and adaptive headlights. The 2.0L turbocharged four-cylinder model was also just announced to be coming to Canada. It's expected to arrive in the spring. The V6 Stinger GT goes on sale this afternoon across Canada.

That’s exactly why the 1916 Ford Model T Touring we tested did such an admirable job exposing the body of our decoy deer at a distance of 100 feet [see below, top right] while several of our modern cars threw their light at the deer’s feet. However, the T’s crude reflectors created a narrow spot beam, barely wider than the car itself, and intensity fell off rapidly beyond 100 feet.

The 2018 Honda Fit’s halogen bulbs are hardly an improvement on a 1997 Miata’s sealed-beam lights. And at just 50 feet out from the car, the bright center of the Mercedes E400’s beam passed below our light meter positioned 24 inches off the ground. The 305-hp Dodge Challenger GT AWD can’t spin its own tires, but it was the Hellcat of headlights in our test. Its HID lamps flooded our testing field with the brightest light in each of the eight measurement locations. It helps that the all-wheel-drive Challenger has an SUV’s stance.

Mercedes-Benz GLE And GLS SUVs Spied Testing Together

  Mercedes-Benz GLE And GLS SUVs Spied Testing Together The next-generation people movers from Stuttgart will gain size while losing weight.Mercedes-Benz is moving forward in the SUV department with updates to both the GLE-Class and GLS-Class in the works. We’ve seen both separately, but spy photographers recently caught the two models testing in the same area. Compared to previous spy shots we’re not really seeing anything new, though the crystal-clear images give us a nicely detailed view of both models.

Lux quantifies the intensity of light as perceived by the human eye. City streets are typically illuminated to about 10 lux at night while the lights in a living room are roughly equivalent to 50 lux. An overcast day is usually around 1000 lux.

The 2019 Mercedes-Benz G-Class Ditches its Front Solid Axle for an Independent Suspension .
Mercedes-Benz doesn’t seem to want to wait for the Detroit Auto Show to talk about its all-new 2019 G-Class which, let’s be honest with ourselves here, looks like every other version of the G-Class that has ever existed since the 1970s. Yet Mercedes-Benz promises an all-new product from the ground …What you need to know is that the new G-Class is new where it counts, and Mercedes-Benz wants to reassure everyone that it will meet expectations in terms of its off-road capabilities and ruggedness. Personally, I am somewhat worried about the fact that the 2019 G-Class will lose its front solid axle in favour of an independent suspension setup.
