Lexus planning a hydrogen fuel-cell LS by 2017

Toyota's Fuel Cell System will certainly migrate to other vehicles in the carmaker's lineup, but Australian car site Motoring reports that one of the models at the head of the queue is the Lexus LS. According to its sources, the executive barge powered by hydrogen will be released by 2017 and take the top spot in the range, rolling in above the LS Hybrid. We're told that Toyota engineers will find a way to slide two hydrogen tanks into its bodywork with the same general setup as on the Mirai – one under the rear seats and another under the rear parcel shelf. The 150-kW fuel cell stack will be placed under the front seats. Motoring says the resulting sedan and its 220-kW electric motor would come in "at around 2,100 kg," which is 4,620 pounds; that's a ginormous 539 pounds less than the listed curb weight of the current LS Hybrid, and 387 pounds more than the standard LS. Assuming all goes as planned, it would have a range of roughly 238 miles, a few dozens less than the Mirai's range of about 300 miles. It would look slightly different, too, the front end getting larger intakes to cool the power unit. It wouldn't surprise us if Lexus does have a hydrogen LS planned – it would be a statement car, and the company likes making statements, even if few heed them; it has stuck with its LS 600h for the past seven years, yet of the 7,539 LS models sold through the end of November this year, only 61 of them were hybrids. The timing would be intriguing, however; by the time the LS hybrid came out, Lexus had already worked over its filet-and-potatoes models. And if the hydrogen version is going to come in above the $120,440 hybrid, well, that will be a statement indeed.

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.

Updated 2016 Lexus LX 570 bows in Monterey

Lexus just pulled the wraps off its 2016 LX 570, and though the updates are minor, they're long overdue. A new one-piece spindle grille – framed by a satin chrome trim – defines the front end aesthetically, and adds a more aggressive look, bringing the eight-passenger SUV up to speed with Lexus's current design language. New LED headlights, turn signals, and foglights further distinguish the front end. The LX 570 adds new wheels, the standard 20-inch split 10-spoke wheels, with an available 21-inch option. While the new LX keeps the brawny 5.7-liter V8 – rated at 383 horsepower, with 403 pound-feet of torque available at 3,600 rpm – it adds a new transmission. For 2016 the LX 570 drops the six-speed in favor of a new eight-speed automatic transmission. This combination means the LX is capable of towing 7,000 pounds, and we expect the 4WD system – the LX flaunts its Toyota Land Cruiser roots – to be as formidable as on the current model. Drivers will appreciate the new Drive Mode Select, which adjusts throttle and suspension calibration with the turn of a dial. The system works in conjunction with the adaptive variable suspension, which adjusts damping, and makes for a smoother ride in the cabin. Drivers can choose from four modes: Eco, Comfort, Sport, and Sport +. The LX gets more standard safety features for 2016, including the Lexus Safety System+, a blind spot monitoring system with rear cross traffic alert, and a tire-specific TPS that gives pressure readings for each tire. Additionally, the multimedia system gets a boost with a new 12.3-inch screen with a remote-touch interface. The Panoramic View Monitor, and "Climate Concierge" are now standard features, while a heads-up display is now an available option. Scroll down for the full details in the press release.
