Why we can't have better headlights here in the U.S.

It wouldn't be a European auto show if we weren't teased with at least one mainstream vehicle we can't have here. At the Geneva Motor Show last week, the small but vocal contingent of shooting-brake buffs lamented that the Mazda6 wagon won't be coming to our shores, although they can take comfort in the fact that the vehicle won't get the torquey 250-horsepower 2.5-liter turbocharged gasoline engine we'll get here. Mercedes-Benz also announced a new headlight technology in Geneva that likely won't be available here anytime soon. It's just the latest in a long line of innovative and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation. Mercedes-Benz's new Digital Light system that debuted in Geneva uses a computer chip to activate more than a million micro-reflectors to better illuminate the road ahead. The Digital Light headlamps works with the vehicle's cameras, sensors and navigation mapping to adjust lighting for the given location and situation and to detect other road users. The Digital Light technology also serves as an extended head-up display of sorts by projecting symbols on the pavement ahead to alert drivers to, say, slippery conditions or pedestrians in the road. And it can even project lines on the road in a construction zone or through tight curves to show the driver the correct path. Digital Light will be available on Mercedes-Maybach vehicles later this year, although like any technology it's bound to trickle down to less expensive vehicles. That is, if we ever get it here in the U.S. Audi, a leader in automotive lighting, has repeatedly run into snags trying to bring state-of-the-art car headlights to the U.S. The German luxury automaker's recently introduced matrix laser headlight system, which performs many of the same trick as Mercedes-Benz's Digital Light, also isn't legal on U.S. roads. And five years after the introduction of its matrix-beam LED lighting, which illuminates more of the road without blinding oncoming motorists with brights by simultaneously operating high and low beams, Audi still can't bring that technology to the U.S. either.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.

Brabus tunes Mercedes-AMG GT up to 600 horsepower

"You can never have enough power," says Brabus in the statement below, "especially in a sports car." Hence the beast you see here. It's based, as you can plainly see, on the Mercedes-AMG GT. But instead of 469 horsepower in the base model or 503 in S spec, Brabus has boosted it up to 600 metric horsepower. That works out to 591 hp by our standards, a figure backed up by an equally impressive 553 pound-feet of torque – up from 443 or 479. With all that power and twist, the Benz tuner of record says its take on the GT will top out at an autobahn-crunching 201 miles per hour, reaching 62 along the way in 3.6 seconds. Of course, Brabus didn't just tinker with the engine and leave the rest alone. It'll build customer vehicles to individual requirements, but has outfitted this demo vehicle with a full aero kit (in clear carbon fiber), monoblock alloys (20 inches up front, 21 at the back), a retuned suspension dropped by 0.6 inches, and a fully refitted interior. We'll be keeping an eye out for the Brabus GT at the Frankfurt Motor Show this week, but judging from the photos above, it would be hard to miss.

At the IAA 2015 in Frankfurt am Main, the exclusive sports program for the Mercedes-AMG GT and GT S models celebrates its world premiere. With an output increase to 441 kW / 600 HP (591 bhp) and a peak torque of 750 Nm (553 lb-ft), the two-seat car reaches a top speed of 325 km/h (201 mph). From the outside, the sports car with BRABUS design impresses with aerodynamic-enhancement components made from clear-coated carbon, ultra-light BRABUS Monoblock F forged wheels, a sports suspension with a multitude of selectable settings for damping and ride height, and a sports exhaust system made from especially lightweight titanium with electronically controlled sound management. BRABUS fine leather interiors and inlays made from real carbon and precious wood upgrade the cockpit of the two-door car. You can never have enough power, especially in a sports car.
