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.

Nearly 700,000 Toyotas and Lexuses named in fuel pump recall

In an announcement posted to its corporate press room, Toyota made known a voluntary safety recall on select 2018 and 2019 Toyota and Lexus models. The recall includes roughly 696,000 vehicles and deals with a fuel pump that might stop working. An internal investigation into the issue is under way.  Affected rides include the Toyota 4Runner, Camry, Highlander, Land Cruiser, Sequoia, Sienna, Tacoma, Avalon, Corolla, and Tundra, as well as the Lexus LS 500, LC 500, RC 350, RC 300, GS 350, IS 300, ES 350, LX 570, GX 460, RX 350 NX 300, RX 350L, and GS 300. The Avalon, Corolla, NX 300, RX 350L, and GS 300 are restricted to 2019 model years, while the others are 2018 and 2019 model years. The potential danger in this issue is pretty obvious. Should the fuel pump stop, the vehicles could sputter, stall, and come to a stop, likely without the ability to restart the cars. Toyota notes warning lights and messages would display should this occur, but by then, it'd be too late. Although Toyota made the announcement this week, the investigation is not yet complete, and therefore, a fix has not yet been specified. The resolution, when determined, will come free of charge to affected customers. Toyota plans to send out notifications for affected vehicles in mid-March. 

2013 Lexus LS460 F-Sport AWD

Gary Approved
There's a guy that goes to my gym who can't get enough of the Lexus LS - let's call him Gary. Gary's the guy - you've probably got one at your gym, or coffee shop, or some other public but quasi-social location - who talks to everyone he meets. Sit next to him on the rowing machine or run by him on the track, and he's almost certainly going to bend your ear for a minute or 20. Gary is in his mid-60s, a business owner, and the super-proud owner of a 2013 Lexus LS.
Not being a shy man, Gary will be the first one to tell you that he didn't do much comparative shopping (he "drove by" the BMW dealership, and looked at a 7 Series "on the computer"). Being a satisfied former owner of multiple Lexus RXs, there was probably only a tiny statistical chance that Gary wouldn't end up in an LS when it came time for him to treat himself to the tricked out luxury car that he'd wanted for a long time. Still, when I found myself chatting with Gary about his new LS, right after I had spent a wintry week in the 2013 LS460 F-Sport AWD, I figured that he'd have some light to shed on the car.
