Audi R8 Exclusive Edition gets laser beam headlights

We've long lamented the National Highway Traffic Safety Administration's draconian Federal Motor Vehicle Safety Standards, which contrary to their name, have actually prevented automakers from selling some substantial and important safety equipment, like advanced headlights, in the US market. Until now, apparently. To be fair, we've known Audi was prepping its advanced laser headlights for the US market, but that doesn't make their arrival any less exciting. Audi will begin offering DOT-approved high-beams that use advanced laser diodes on a limited run of V10-powered R8s. Exclusive to the, um, Exclusive Edition R8, the advanced lamps complement the standard LED low beams and dynamic front turn signals, offering "very bright and pure white light" for 25 lucky consumers. Here's some more techno babble about how the lights work – according to Audi's official release, there's a laser module in each headlight containing four high intensity laser diodes that fire out blue lasers. Then, a phosphor converter adjusts the 450-nanometer laser into visible light that fires up above 40 miles per hour. "When conditions permit," Audi's release reads, the laser high beams "greatly enhance visibility for the driver by projecting a low and wide beam of light on the road ahead." Naturally, we have questions, but Audi wasn't keen on releasing much info ahead of the R8 Exclusive Edition's Los Angeles Auto Show debut. The company confirmed that the new lights are DOT approved, which makes sense considering the LA introduction. We're also wondering how Audi's new Laser Lights differ from BMW's similarly named Laserlight system, offered on the i8. Both setups use lasers to replace conventional high beams, but BMW says it "adjusted to the maximum allowable light output for the US market." Audi was cagey about explaining if it modified the system to satisfy the feds. Ingolstadt also offered the typical "we don't comment on future product" when asked about future applications for its laser headlight technology. Beyond the advanced high-beam headlights, the R8 Exclusive Edition comes standard with Quantum Grey paint, 20-inch "Y Design" wheels, a carbon-fiber side blade with an orange stripe, and a whole bunch of interior trim upgrades, like full leather upholstery and Alcantara trim. Price start at $229,200, not counting $1,250 in destination charges. We'll have more on the R8 and its laser lamps when it debuts in a couple weeks. Related Video:

2019 Infiniti QX50 vs. compact luxury SUV rivals: How they compare

With apologies to the EX35, or whatever it was eventually renamed, Infiniti has been without a proper, competitive entry in the compact luxury SUV segment. You know, the segment that's growing faster in sales and entries than any other? To say the 2019 Infiniti QX50 is long awaited would therefore be an understatement. At first glance and drive, the new QX50 would indeed seem to be wildly more competitive than its predecessor, which come to think of it, was eventually called the QX50 as well. This one is based on an all-new front-wheel-drive platform, and although it lacks the inherent verve of the old, rear-drive- and 370Z-based one, the resulting increase in cabin space should be a welcome tradeoff. In fact, as you'll see below, the QX50 has gone from one of the smallest compact SUVs to the most spacious. How does it stack up in every other way? Say, against the segment's four best-selling entries last year: the 2018 Lexus NX 300, 2018 Acura RDX, 2018 Audi Q5 and 2018 BMW X3. On paper at least, really well as it turns out. Let's go to the spreadsheet! Discover and compare other luxury crossovers with our Car Finder and Compare tools. Comparing engines, drivetrains and transmissions With the exception of the Acura, all of the contenders come with 2.0-liter turbocharged four-cylinder engines. As you can see, the Infiniti is the heavyweight amongst the four-bangers, boasting the most horsepower and torque. The Acura V6 nips it by 11 hp, but the QX50 is still the overall torque champ. Plus, as we documented in the QX50 first drive, the Infiniti's new VC-Turbo engine is also the most technologically advanced. The Lexus is the wimp of the group and is also the second-heaviest, which isn't exactly the ideal scenario. The Infiniti is the only one in the group to feature a continuously variable transmission. That's not going to generate much applause around here. The BMW tops the gear count with eight, while the Audi is the only entry with a dual-clutch automated manual. The Acura and Lexus have only six gears, but they're good transmissions and it's not like their fuel economy is off the pace. The Audi and BMW come standard with all-wheel drive, while the others offer a choice of front- or all-wheel drive. Comparing cargo and interior space The new front-wheel-drive platform is paying dividends inside for the 2019 QX50, as it now boasts the most maximum cargo space at 65.1 cubic feet.

Audi SQ7 TDI packs 48V electric compressor, 664 lb-ft

Take a look at the new Audi SQ7 TDI. It's the first time Audi has done an S performance version of its flagship sport-ute, and packs under the hood a 4.0-liter V8 turbo diesel engine mated to an eight-speed automatic and all-wheel drive. It produces a potent 435 horsepower, and an absolutely bonkers 664 pound-feet of torque. The Audi SQ7 TDI produces a massive 664 lb-ft of torque. Impressive as it is, though, that doesn't even tell the full story. That's enough to make us forget it wasn't there in Geneva. It's also more torque than just about anything the Volkswagen Group makes – short of the Bentley Mulsanne Speed and the new Bugatti Chiron. Not even the Lamborghini Aventador SV or Bentley Continental GT Speed can touch that torque figure. Nor can competition like the Porsche Cayenne S Diesel (with its 385 hp and 627 lb-ft) or the BMW X5 M50d (381 hp and 546 lb-ft). It may not surpass the old twelve-cylinder Q7 6.0 TDI (with its 493 hp and 738 lb-ft), but still trounces the VW Touareg V10 TDI (309 hp and 553 lb-ft) – which was strong enough to tow a jet airplane, while the new SQ7 is fast enough to out-drag one (as you can see from the video below). Impressive as it is, though, that headline-grabbing torque figure doesn't tell the full story. To get there, Audi employed two conventional, sequential turbochargers and a third compressor that – in an industry first that's been a long time coming – is powered electrically. The engineers in Ingolstadt installed a beefier 48-volt electric subsystem to power the electric compressor (among other systems) and its latest valvetrain tech for the first time in a diesel. The result, Audi says, is a lack of any perceptible turbo lag – and a 0-62 time quoted at 4.8 seconds, en route to the typical electronically limited top speed of 155 miles per hour. As if that weren't enough, Audi also equipped the SQ7 TDI with an optional suspension package that coordinates the activities of three systems. There's a differential, a four-wheel steering system, and a clever electromechanical roll stabilization system that employs an electric motor (made possible once again by that 48-volt system) and a three-stage planetary gearbox to keep it all level and improve ride quality over rough surfaces. The sum total is an impressive technological tour de force on Audi's part, but one that we may just have to admire from afar.
