Next Lexus RX looks ready to roll

Lexus' bread-and-butter crossover, the RX, has been long overdue for a substantial redesign, with the current third-gen crossover entering its sixth year on sale. Considering this, it's no surprise that the fourth-generation RX is well on its way to production readiness, as evidenced by our latest round of spy photos. This new model looks larger than the current RX, like the wheelbase has been stretched, which would likely explain reports that the company was looking at an optional third-row for the mid-sizer. Aesthetically, the Lexus spindle grille is easy to spot, as are its aggressive headlamps. It's unclear based on these images if the RX will adopt the same styling statement seen on the RC, IS and NX, with sharp LED running lamps mounted below the actual headlights, but it certainly seems likely. Besides the design changes, our spies report that Toyota will be working hard to shed weight, likely through the use of aluminum for the doors, hood and rear hatch. Underhood, expect the typical combo of a gas-powered six-cylinder as well as the V6/hybrid setup found in Lexus' 450h models. As for when we could expect to see the next-gen RX, your guess is as good as ours. Geneva is, as always, a candidate, as is April's New York Auto Show. Of course, should we confirm a debut at either show, we'll be sure to let you know. Stay tuned.

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.

2015 Lexus RC 300h is a hardcore hybrid cherry coupe

Lexus is tag-teaming back into the hardcore coupe ring with this, the red rum RC 300h that's jumping off the top rope to "[inject] emotional appeal into the Lexus DNA." It's the hybrid version of the twin, powered by a 2.5-liter V6 aided by a 105-kW electric motor, the pair putting out 217 total horsepower and 280 pound-feet of torque through a continuously variable transmission. The RC's other, more conventional half will come with a 3.5-liter V6 with 314 hp and 380 lb-ft shifted with an eight-speed sequential transmission.
The brand doesn't want you to take this RC Coupe for a two-door version of the IS. It's based on the GS platform but its dimensions are unique, being wider, lower and shorter in wheelbase than the IS. Concept-car headlights flank the most extreme version of the spindle grille yet seen on a production car, and the lighting novelty continuing in the cabin with illumination that is aimed up instead of down. The package will ride on either 18- or 19-inch wheels.
The "high contrast," dual-zone cabin is graced with shimamoku wood and Lexus' Remote Touch Interface, and Lexus says the seats have been conceived via an "integrated foaming construction method" like racing seats - we think they look spectacular stitched up in this carmel-colored leather.
