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.

PSA: Toyota wants to save your life, needs an hour of your time

Toyota wrote Autoblog to ask if we could spread the word about the Takata airbag inflator recall. Defective inflators remain installed in tens of millions of cars made by 19 carmakers, with manufacture dates that go back to the year 2000. Each inflator compounds the risk of serious injury or death in an airbag-activating crash. With a new ad campaign called "in about an hour," Toyota wants to make sure that unaware owners, or overly busy owners, know they can get their Toyota, Lexus, and Scion vehicles repaired free of charge in about the time it takes to do a load of laundry. The campaign focuses on cities in three so-called Zone A states where hot, humid climates worsen the threat of the ruptured inflators: Los Angeles, Dallas, and Miami. However, every owner everywhere who cares about his life, or his child's life, should at least check to see if his car is affected. All it takes is a quick VIN entry at the dedicated recall site at Toyota.com/Recall. The results will let you know if your car is affected and, if so, locate a local dealer for the free fix. The National Highway Transportation Safety Administration said the Takata affair has become "the largest and most complex safety recall in U.S. history." The numbers so far suggest the recall covers more than 42 million vehicles and more than 60 million airbags. Autoweek keeps an updated list of Takata information, including every make and model on the recall list. Consumer Reports published a list of frequently asked questions covering issues directly related and tangential to the recall. The 19 automakers maintain pages dedicated to the issue; Fiat Chrysler lists every relevant model and how it prioritizes repairs by Zone, Honda says it offers a free rental car while owner cars are repaired, Daimler vans says its fix only takes about an hour. And of course NHTSA serves all owners with its own VIN lookup site. We encourage you to check your vehicle — the life you save could be your own. Related Video:

Lexus LC 500 dominates 2016 EyesOn Design Awards

The Lexus LC 500 captured top honors for the best-designed production car and the best interior at the 10th annual EyesOn Design awards at the Detroit Auto Show. The awards are handed out by the Detroit Institute of Ophthalmology. The Buick Avista won the concept car category, just as its four-door predecessor, the Avenir, did last year. Other winners this year included the Chrysler Pacifica, which won for the best-designed production "truck" (as crossovers and minivans are sometimes categorized), and the Audi H-Tron Quattro, which won for the best concept truck. The Acura Precision concept was also recognized for its "innovative use of color, graphics, and materials." And the new Volvo S90 was singled out for its human-machine interface. The panel of jurists this year included designers from an array of automakers and art schools. Several past honorees for the organization's LifeTime Design Achievement Award participated in the voting, including GM's Wayne Cherry, BMW DesignworksUSA founder Chuck Pelly, Hyundai's Peter Schreyer, and Jack Telnack (formerly of Ford). Telnack also served on the select panel of chief judges this year, alongside Chris Chapman from Hyundai, Dave Marek from Acura, and Stewart Reed from the Art Center College of Design.
