Lexus hints at LF-SA concept bound for Geneva

Lexus has been moving steadily away from its once conservative designs with increasingly aggressive ones, and looks set to move the bar once again with this latest concept. Bearing the codename LF-SA, the new Lexus concept is set to debut in a couple of weeks at the Geneva Motor Show. But the Japanese luxury automaker isn't giving us much to go on from the decidedly enigmatic teaser image and brief statement below. According to Lexus, "the LF-SA Concept explores unexpected territories for the brand," which could come down to a new compact model to either replace or slot in below the CT 200h in the brand's lineup. The upright form would seem to be consistent with a city car. Beyond that, we can see an even larger evolution of Lexus' trademark spindle grille and checkmark accent lights. Whatever it is, though, Toyota's luxury division promises it will remain "a driver-focused vehicle." We'll just have to sit tight and wait to find out more, so watch this space. 17 Feb 2015 WORLD PREMIERE OF THE LEXUS LF-SA CONCEPT AT THE 2015 GENEVA MOTOR SHOW Lexus will reveal its all-new concept, the LF-SA at the 2015 Geneva Motor Show. Brussels, Belgium - An illustration of Lexus' passion for upcoming design trends, the LF-SA Concept explores unexpected territories for the brand in a bold and emotional execution. In a future world which many people see as increasingly influenced by technology and virtual experiences, the LF-SA Concept is also a driver-focused vehicle, reflecting Lexus' vision that real experience will remain ultimate luxury. The LF-SA Concept will be revealed at the Lexus Press Conference taking place on March 3, 2015 at 12:30 PM at the Lexus stand (number 4211) in Palexpo, Hall 4.

Are you the 2015 Lexus RC F?

With less than two weeks before the start of the 2014 Detroit Auto Show, we're starting to get a better idea of what some of the hot debuts are for this year's installment of America's premiere auto show.
The latest leaked image to hit the internet is what purports to be the Lexus RC F, the Japanese premium brand's long-awaited return to the coupe market and the latest challenger for the upcoming BMW M4, a model that will also be arriving in Detroit. This image was reportedly originally leaked by a Chinese magazine, and was then picked up by our friends at AutoExpress.
The image fits with the teasers and spy shots we've seen of the car so far, meaning that this could very well be the real deal. As we've previously reported, Lexus is expected to offer the RC F with a 460-horsepower V8, while a lower-power RC 350 with two fewer cylinders will also be available. We'll have the full set of details on the RC F when it hits the stage in Detroit.

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.
