Toyota's hydrogen fuel cell Mirai isn't good enough to be a Lexus

It looks like the first hydrogen fuel-cell vehicle from Lexus will be faster than previously advertised, but it will get to the market slower than expected. It's all part of the paradox involved with Toyota looking to broaden its fuel-cell technology beyond the Mirai. Either way, the first Lexus fuel-cell vehicle is slated to start sales by the end of the decade, said Auto Express, citing comments from Alain Uyttenhoven, head of Lexus Europe. Uyttenhoven noted that it'd take an SUV to provide enough space to accommodate the packaging for the Lexus fuel cell powertrain. That comment may imply that the hydrogen-fueled powertrain from Lexus will offer similar performance to that of the Lexus RX450h hybrid SUV. That model delivers 300 horsepower and boasts a 0 to 60 mile-per-hour time of about seven seconds. Such a mill would be a departure from what we'd previously reported on Toyota's plans to expand its fuel-cell technology to its Lexus luxury badge. With Toyota believed to be planning to unveil as many as three fuel-cell models in time for the 2020 Summer Olympics in Tokyo, the Japanese automaker said early last year that it may have a Lexus fuel-cell vehicle available as soon as 2017, while reports suggesting the model would be a Lexus LS-based sedan. Additionally, the Mirai's fuel-cell powertrain had been believed to be the platform for the proposed Lexus fuel cell from the moment that model started sales in California last year. Apparently, though, the Mirai's 152-horsepower powertrain, coupled with a full-tank range that would be about 20 percent less than the 300-mile Mirai, isn't up to snuff for Lexus duty.

Production Lexus RZ 450e leaked ahead of official debut

The Lexus RZ 450e isn't supposed to debut until April 20, but some screenshots from Japan may have revealed the production EV's look. Unsurprisingly, they look pretty close to the official concept images we've seen before. In some ways toned down for production, in other ways amped up. The images appear to have been leaked in a Japanese Discovery Channel promo, which users at RZforums.com screen captured. The screenshots show a burnt orange-colored RZ driving on a test course in Japan. The inescapable dress-up comes in the form of a black hood that emphasizes the Lexus spindle grille. Though it's been in use for over 10 years now, it remains a controversial piece of Lexus design. It works better on some cars than others, but in the case of the RZ the company seems to want to double down on accentuating its lines. On the other hand, the concept's body-colored nose seems to have been replaced with a black section where the grille might have resided on a internal combustion car. This lets the RZ maintain a semblance of grille without actually having one. The result is a more traditional-looking face than the Mirai-esque concept schnoz. It should be noted that the production car wears a black roof as well, which the concept does not. Overall, the Lexus RZ's styling departs further from the Subaru Solterra and Toyota bZ4X upon which it is based. While those two are nearly indistinguishable from one another, the Lexus has unique sheetmetal as evinced by its surfacing, C-pillar treatment, and more. Perhaps as the biggest relief to some, the RX eliminates the black cladding on the front fenders for body-colored wings. The Toyota bZ4X is powered either by a single electric motor with 201 horsepower or a dual-motor, all-wheel-drive configuration with 214 horses. Both choices use a 71.4-kilowatt-hour lithium-ion battery that gets, in the Japanese testing cycle, 310 miles of range in front-drive and 285 miles in all-wheel-drive. The Lexus might get a performance boost, but we won't know until April 20 at the latest. Related video: This content is hosted by a third party. To view it, please update your privacy preferences.

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.
