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.

Lexus teases 2022 LX 600 flagship SUV

Like so many things at the moment, the Lexus LX debut got pushed back, but it's nearly upon us. Toyota's luxury brand began the teaser campaign for the 2022 Lexus LX 600 today, in preparation for an online debut October 13 at 12:30 p.m. Eastern at the same time the vehicle is unveiled live in the United Arab Emirates and Saudi Arabia. We can glean a few things from the teaser, the first being the same Lexus design language we recently saw on the 2022 NX transferred to what will be the automaker's flagship SUV. That means an LED light bar connecting two hockey-stick taillamps above a spelled-out "LEXUS" instead of the Lexus logo. The chrome accents of the LX 570 are history, the rear license plate placed in an unadorned trapezoidal recess. The rear bumper is now nearly flush with the tailgate and loses its stanchions at the edges.    And then there's that LX 600 badge, officially signaling that numbers aren't about engine displacement. Depending on market, the LX is expected to get the twin-turbocharged 3.5-liter V6 that launched with the 300-Series Toyota Land Cruiser in June and puts out 409 horsepower and 479 pound-feet of torque in that model. Japanese outlet Creative Trend says this mill will eventually get hybrid assistance to create an LX 750h trim with 480 hp and 642 lb-ft. of total system output. The 3.3-liter diesel V6 with 305 hp and 516 lb-ft. could end up in places like Japan and Australia, and it's possible a base version with the naturally aspirated V6 finds its way to market.  Toyota said putting the new Land Cruiser on its TNGA-F platform saved about 440 pounds. We won't be surprised if the Lexus loses some weight as well, but we also expect a lot of new tech in the LX 600, and luxury is heavy. Features like the Multi-Terrain Select system and Multi-Terrain Monitor seem like shoo-ins, as does the 360-degree camera system. An option for fingerprint authentication to start the vehicle might bow as well. We'll know next week when the 2022 LX livestream kicks off. Related Video: This content is hosted by a third party.
