Lexus Bladescan is another new headlight safety breakthrough U.S. won't get

Lexus is back at it with innovative lighting technology. The BladeScan headlights available in Europe on the 2020 RX utilize a new mechanism for throwing light further down the road, aiming that light more precisely, and doing so without blinding other road users. Lights from other OEMs with the same capabilities have increased the number of LEDs inside the housing for finer control. The BladeScan module inside the Lexus lights holds the number of LEDs down to 10 on each side of the RX, which Lexus says is a more cost-effective solution. In fact, BladeScan uses fewer LEDs than Lexus' most recent adaptive high-beam system, which has 24 LEDs on each side. The LEDs in the new module are arranged in two rows, eight on top, two on bottom. The diodes are fed information about objects ahead, and adjust their intensity to dim light aimed at an oncoming car, or illuminate a pedestrian by the roadside. However, the LEDs don't shine their light down the road, they shine their strobing light onto two blade-shaped mirrors — hence the name BladeScan — that rotate at high speed. The light reflects off the mirrored blades and into a lens, which orients the beam down the road. Not only is the reflected light easier to handle for oncoming drivers, the system has aim accurate to 0.7 degrees. Lexus' current adaptives are accurate to 1.7 degrees, making BladeScan a 143-percent improvement. That means the new feature can throw even more light into areas that are hard to reach with current lights — Lexus says pedestrian recognition at night has increased from 105 feet to 184 feet. Buyers of the 2020 RX will be able to take advantage when the new crossover goes on sale in Europe later this year. Naturally, U.S. Federal Motor Vehicle Safety Standard No. 108 means we won't get BladeScan — that goes for you, too, Canada. The now-52-year-old U.S. law mandates a single low beam and a single high beam setting, with no intermediate settings and no activation of high and low beams simultaneously. Toyota, Audi and BMW have been trying for six years to get FMVSS 108 changed to permit new and potentially lifesaving headlight technologies. The automaker wrote in a statement to Carscoops, "Last December, Lexus submitted a petition to NHTSA to allow ADB in the United States. Currently, we await the Agency's decision and hope to see an amendment in FMVSS 108."

2021 Lexus IS teased, will be revealed next week

While the larger Lexus GS has finally been discontinued after declining sales, its smaller sibling is getting a new generation. The new 2021 Lexus IS will be revealed next week, and in the meantime, Lexus released this teaser image. It doesn't reveal too much, and the company was smart enough to make some adjustments so that playing with exposure and brightness in Photoshop wouldn't reveal anything more. All we can tell is that it's a sedan, it gets a full-width taillight design, and there's a bit of a diffuser treatment to the rear bumper. Lexus does confirm that this generation will be rear-wheel-drive, not that we were worried that would change. What we're left wondering is what will power those wheels. Previous rumors have speculated it could get a BMW inline-six from the Supra and Z4. Others have reported the current range of engines, including a turbo four-cylinder and a naturally aspirated V6, will carry over, and the 5.0-liter Lexus V8 could join the group. Fortunately we won't have to wait long to know the truth. The Lexus IS will be revealed on June 9. You can be sure to see it here on Autoblog. Related Video:    

Why is there a huge bulge in 2021 Lexus IS 300 AWD's driver footwell? We explain

After an initial turn a few weeks ago for the 2021 Lexus IS first drive review, the revised luxury sedan has returned to the Autoblog garage for a second look. This middle-of-the-road IS 300 AWD pairs a 260-horsepower V6 with a six-speed automatic transmission and four driven wheels, and frankly it's the least interesting way to spec out the redesigned sedan. While there are cars in this segment designed to get a performance boost from their all-wheel-drive systems even in dry conditions, the IS isn't one of them. Adding insult to injury, you get stuck with a cramped driver-side footwell care of the engineering shenanigans that went into making this system possible.  While we've mentioned this particular compromise before, we rarely touch on the reasons why it exists in the first place. The fundamentals are fairly obvious; the standard IS utilizes a longitudinal, rear-wheel-drive powertrain. As is typical with this configuration, the transmission sits in a tunnel beneath the center console. This arrangement works just fine, provided you don't need to power the front wheels.  To do so in a traditional car like the IS requires a literal end-around maneuver involving the engine and transmission, which we've diagrammed for you below care of MSPaint. This is a bit simplified for the sake of this write-up, and it should be noted that this is not the only way to implement AWD in an inherently RWD platform, but it illustrates how the power for the front axle (red) and rear axle (blue) flows from the transmission to the drive wheels. To get juice flowing to the front axle, Lexus had to add a parallel output shaft, exiting the transmission from the front with enough clearance for the bell housing and engine, which sits between the transmission and the front differential. This requires quite a bit of lateral reach, meaning the housing has to extend much farther out than usual to accommodate it (yellow arrow). As a result, the all-wheel-drive transmission looks a lot like a sci-fi gun with a chunky drum magazine hanging off the side of it. The hump (above right) in the footwell is there to clear this protrusion. This basic configuration isn't unique to Lexus. In fact, if you look at a BMW xDrive cutaway, it's similar. So, why no "hump" in other cars? There are multiple factors, but to boil it down to what is most relevant, it's a combination of the resulting shape of the Lexus transmission housing and the size of the IS chassis.
