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.

Apple uses Logitech steering wheels and pedals to control autonomous cars

SAN FRANCISCO (Reuters) - Apple outlined a plan to train operators of self-driving cars in documents submitted to California regulators earlier this month, the latest clues to the company's autonomous vehicle technology aspirations. Apple was granted a permit to test self-driving cars on April 14 by the California Department of Motor Vehicles but the company has never said anything about its plan. The state released 41 pages of Apple application documents to Reuters that give some clues about the company's highly secret self-driving effort, which it has never openly acknowledged. The iPhone maker joins a long list of carmakers, start-ups and technology rivals, including Alphabet's Waymo, that are testing cars on state roads. Apple is looking for new hit products and autonomous car technology is expected to revolutionize the traditional auto industry. As part of the application, Apple included a 10-page training plan that appeared to be related to operators taking back manual control of the car during automated driving exercises of the system, which it calls a development platform. Business Insider reports that Apple engineers riding in the back seats have the ability to take over control of the car using off-the-shelf steering wheel and pedal video game controllers from Logitech. Apple declined comment beyond the filing. The plan includes a document called "Automated System: Development Platform Specific Training Overview" whose objective is "to train safety drivers in various automated driving conditions." "Development platform will be controlled electronically (e.g. joystick) and safety drivers must be ready to intervene and take control," the document reads. The document highlights different scenarios to be tested, from high speed driving and tight U-turns to lane changes. One letter sent from Apple to the state Department of Motor Vehicles noted that Apple's development platform "will have the ability to capture and store relevant data before a collision occurs." The document does not include detail on how Apple's self-driving platform actually works or other technical details. It also does not say what kind of sensors are found on Apple's three permitted vehicles, all 2015 Lexus model RX450h. The permit does not necessarily mean that Apple itself is building a full car. Apple could instead be designing a self-driving platform that can be integrated into other manufacturer's cars. (By Alexandria Sage.

2022 Lexus LS 500 gets subtle changes, the same price

The Lexus LS 500 glides into 2022 with a modicum of changes. The most notable update for new owners will be the retuned suspension, spring and damper rates adjusted to provide a more comfortable ride and anti-roll bars enlarged to tamp down body roll. On sedans optioned with the adjustable-ride-height function, Lexus said that feature has been "enhanced" to make getting in and out even easier. Output from the 3.5-liter twin-turbo V6 doesn't change from 416 horsepower and 442 pound-feet of torque, but a trio of tweaks are said to upgrade the experience. Reshaped tops on the pistons deliver "quiet operation when cold" — as if engine noise has ever been a Lexus problem — and lower emissions. New wastegate control logic means better turbo efficiency. And the 10-speed automatic transmission gets recalibrated shift mapping to keep the engine in the meatier part of the power band. The other changes for every LS 500 trim start with Lexus making its Safety System+ 2.5 standard across the range. This adds active safety features like Pre-Collision System (PCS), Frontal Collision Warning (FCW), Automatic Emergency Braking (AEB), Pedestrian Detection and Bicyclist Detection. Inside, Lexus says the infotainment system "provides additional control options for driver and passenger," without going into what those are. Those who option the Luxury or Executive Packages can get a new foil interior treatment called Haku. This is derived from 400-year-old the Japanese art of decorative gold leaf, the most well known being Kanazawa-haku, the leaf made by hammering gold until it was one or two ten-thousandths of a millimeter thin. Yes, you read that thickness correctly. The foil is so delicate that Lexus says it has to be applied by hand. Lastly, the 2,400-watt, 23-speaker Mark Levinson stereo can be optioned on the entry-level LS for the first time. Prices don't change from the current MSRPs for the 2021 sedan, the base LS 500 with rear-wheel drive starting at $76,000 and adding a $1,075 destination charge for $77,075 total. The rear-driven LS 500 F Sport starts at $80,675. Optioning either with AWD costs another $3,250. Related video: This content is hosted by a third party.
