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.

Autoblog Minute: UAW and FCA avoid strike, Clarkson teases new show

FCA avoids a worker strike, a former Top Gear host teases us with a picture from Amazon's new car show, and Toyota predicts autonomous cars by 2020. Autoblog senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] FCA avoids a worker strike, a former Top Gear host teases us with a picture from Amazon's new car show, and Toyota predicts autonomous cars by 2020. I'm senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. A UAW strike of FCA was avoided thanks to a zero-hour tentative agreement reached this week. Worker concerns that were renegotiated in the new [00:00:30] deal include adjustments to the two-tier wage scale, health care costs, and production outsourcing. Now check-in with Autoblog as we update our reports on this evolving story. Shooting began on Amazon Prime's new automotive show starring the former Top Gear crew. That's Jeremy Clarkson, Richard Hammond, and James May. Now Clarkson threw out a tweet from day one of filming on location at Algarve Motor Park in Portugal. The picture features the show's [00:01:00] three stars and crew posing with the holy trinity of hyper cars. That's a McLaren P1, a Ferrari LaFerrari, and a Porsche 918 Spyder. This Prime show is being called Gear Knobs though the name is unofficial. Now if a tweet is any indication of what we can expect, who cares what it's called this is gonna be awesome. (Eds Note: Clarkson tweeted Friday that the show will not be called Gear Knobs.) Toyota predicts drivers could be obsolete on highways as early as 2020, with technology dubbed the Toyota Highway Teammate or THT. Toyota is using a modified [00:01:30] Lexus GS to show what this is capable of. THT is already able to create a driverless freeway car that's capable of changing lanes, making passes and taking curves. Plus, it can keep safe distances from other vehicles. Toyota is currently testing this on Tokyo's Shuto Expressway. Those are the highlights from the week that was. Be sure to check out my full recap this Saturday. And I'll have some added insight on the BMW M4 GTS. For Autoblog, I'm Greg Migliore. [00:02:00] Show Logo Autoblog Minute is a short-form video news series reporting on all things automotive. Each segment offers a quick and clear picture of what's happening in the automotive industry from the perspective of Autoblog's expert editorial staff, auto executives, and industry professionals.

NHTSA may investigate new Toyota unintended acceleration case

After paying a $1.2-billion settlement to the US government last year, Toyota largely put the unintended acceleration recall behind it. Although, there were still some civil lawsuits to handle. A new case where the owner of a 2009 Lexus ES350 is petitioning the National Highway Traffic Safety Administration to open another analysis could draw the issue back to the forefront. Investigators are still deciding whether to research these claims further, though. According to this petition, the owner's wife was driving the ES350 in February 2015. While pulling into a parking space, the sedan allegedly surged forward, and there was a low-speed accident. The claim asserts there are at least two other similar cases in NHTSA's database: one in a 2009 Camry in 2009 and another in a 2010 Corolla in 2014. Specifically, this person wants an "investigation into low-speed surging in different models of Toyota automobiles in which the car starts accelerating and the engine RPM increases even when the accelerator pedal is not depressed," according to the agency. NHTSA will do further research into this person's claim and will decide whether to conduct a full investigation into the alleged issue. This won't be the first reappraisal of unintended acceleration in Toyotas by the agency in recent months, though. Between September 2014 and May 2015, NHTSA evaluated a similar petition with allegations covering 2006-2010 Corollas, and the government body decided to deny that one because the problem couldn't be replicated.

The petition was prompted by a February 2015 crash involving a model year (MY) 2009 Lexus ES350, which allegedly surged as the petitioner's wife was pulling into a parking spot.
