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.

'Next Lexus F' teased ahead of Detroit debut

We've got absolutely zero actual information from the automaker on what its "Next Lexus F" will be, other than what was just released today in this brief press release and lone teaser image, but our best guess is that it's the next-generation IS-F sedan. The timing would make sense, considering that the latest IS just hit the market earlier this year as a 2014 model.
Since we know so little, we'll just share some of the exuberant marketing speak contained in the press release for your reading pleasure:
Designed from the asphalt up, to strike at the heart, the newest Lexus F model will debut at the January 2014 North American International Auto Show in Detroit.

Lexus RC facelift: Here's an official look

After the updated Lexus RC coupe was spied testing last month, Lexus has released official images of the RC coupe's upcoming refresh. The facelifted car will debut at the Paris Motor Show in early October, but the automaker is already offering a good look at the RC's improvements. The 2014-introduced RC is getting a subtle set of updates, and Lexus says these changes will sharpen it both as a driver's car and as a grand tourer. As well as improving aerodynamics, Lexus has honed the RC's suspension and powertrain: There are new shocks and stiffer bushings along with a new set of 19-inch wheels; the car's footprint has been altered and its center of gravity lowered. The rear-wheel-drive RC300's 2.0-liter turbo engine has also had its throttle response fine-tuned. As for aero, there are changes in the side window moldings and a new rear bumper duct to aid airflow and to make the RC more stable on the road. Lexus now calls the RC both razor-sharp and extremely supple; eventual test drives will confirm how much the handling has improved. There's no mention of changed power figures. The RC's looks remain largely unchanged, with noticeable alterations mainly to the headlights and bumper corners along with the spindle grille's mesh; the headlights are now one-piece compared to the old split design that featured a lower "Nike Swoosh" separate from the main headlights. There are new colors, including Naples Yellow and Sparkling Meteor, and the interior colors and trim have also been refreshed: Black leather seats are now available with eye-catching Mustard Yellow side bolsters. A new analogue clock has been borrowed from the LC, as well as other interior styling improvements influenced by the bigger coupe sibling. All in all, it seems the RC is getting subtly infused with the LC's appearance. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.
