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.

The 2021 Lexus LC 500 Convertible is blissful, motoring beauty

Exquisite, grand, beautiful. Any of these words and more like them could be used to describe the 2021 Lexus LC 500 Convertible’s design. They also apply to the noise made by LexusÂ’ 5.0-liter naturally aspirated V8 engine. In fact, go down the list. The interior is just as stunning. Its handling defies the 4,557-pound curb weight. Sure, the infotainment system is hot garbage to use, but Â… who cares? Messing with a formula as perfect as the LC 500 Coupe is dicey business. That said, these designers already had one mic drop moment. WhatÂ’s a second with the Convertible? One look at the dazzling drop top is enough to turn anybody into a believer. The original LC was essentially just the LF-LC Concept brought to life in production form. Few (if any) designs of the past decade have transitioned so gloriously from the make-believe world of concept cars to production vehicles. Seeing the LC parked amongst Ford Explorers, Chevy Tahoes and other regular fare at a grocery store brings into focus how unprecedented the design is. It looks as though somebody ripped the car straight out of a fantasy novel and stuck it on city streets. The first time I drove the LC, some guy and his friend followed me for several miles until I arrived at my destination, just to scramble out of their car and get a closer look. ThatÂ’s the kind of car this is. Many years from now, there will be beautifully preserved examples of them sitting on the grass at concours shows across the country, rightfully taking its place as a shining example of peak car design from this era. And yes, those are heady words. But look at it! The Lexus spindle grille that looks so awkward and out of place on some Lexus models fits the LCÂ’s face. ItÂ’s complemented by a striking triangle-shaped triple-LED headlight design. Lexus designed the front LED daytime running lights to swoosh in the same shape and style of the grille, too. There are no obnoxious or unnecessary fake vents (looking at you, Supra). ItÂ’s not trying to be a muscle coupe with a super aggressive chin or bulging hood. The front is just clean, pointed perfection. ItÂ’s when we get to the A-pillar that the Convertible begins to diverge from the Coupe. Connecting to the top of the pillar is, well, a roof.

2014 Lexus IS gets TRD bits

Toyota Racing Development (TRD) in Japan has designed cosmetic and performance bits that give the 2014 Lexus IS a front-to-back workover. Different from the F-Sport parts we expect from Lexus here, the full body kit runs 437,700 yen ($4,285 US) and starts with air deflectors at the lower edges of the front bumper, through to side skirts, a decklid spoiler and a rear bumper with a diffuser and quad exhaust tips.
For 288,750 yen ($2,830) you can sharpen responses with new shocks, springs, dampers, sway bar and bracing. The priciest individual component is the set of 19-inch wheels, four of them going for 527,625 yen (5,170 US). There's no word on US importation or pricing yet, but done up all in black like the IS above, we wouldn't mind seeing it here.
