Toyota to suspend 18 assembly lines as production restarts post-quake

TOKYO - Japanese manufacturers began restarting production at plants in the country's quake-hit northeast, but Toyota Motor Corp said it plans to idle 18 assembly lines for a few days next week due to a shortage of parts from suppliers. It had suspended operations at three factories due to the quake and sees lost production of 20,000 units due to the stoppages. Toyota has already cut its global production target due to the ongoing chip shortage. The suspension will cut heavily into Toyota's domestic production. Impacted product lines include the Toyota RAV4, Land Cruiser, Harrier and Yaris and virtually every Lexus. Toyota did not say whether these shutdowns could extend to U.S.-based production lines, but the possibility exists if they receive parts from the same suppliers.  On one hand, the limited damage caused by the magnitude 7.4 temblor has highlighted Japan's success in building resilience against the frequent tremors that shake the archipelago. But the quake has sparked concerns of further disruptions to a pandemic-hit supply chain for precision components vital to electronics and autos production and in which Japanese manufacturers play a leading role. Murata Manufacturing Co Ltd, the top global supplier of ceramic capacitors used in smartphones and cars, said it restarted production on Friday at two stopped plants with the remaining two idled plants to restart next week. A fire that broke out at a factory which produces chip inductors caused some damage to equipment. Renesas Electronics Corp, which makes nearly a third of the microcontroller chips used in cars globally, said it has restarted production after stopping it at two factories with a partial stop at a third. All three factories, including the Naka factory where fire broke out last year, are expected to return to pre-quake capacity by Wednesday, Renesas said. Power has mostly been restored across the northeast, which suffered Japan's biggest earthquake 11 years ago. Areas of Tokyo lost power for nearly three hours after the latest quake, in which three people died and 183 were injured. The blackout has forced the disposal of some COVID-19 vaccines held in cool storage, the Yomiuri newspaper reported. Tech conglomerate Sony Group Corp is in the process of gradually restarting production at three factories in the quake-hit area, a spokesperson said.

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.
