The revolutionary Bose suspension that could have been

The Bose name pops up on these pages every once in a while – usually, as you might expect, because some automaker or another has installed its audio systems in one or more of its models. But a few years back, the research-driven audiophiles at Bose developed a revolutionary adaptive suspension system that could have been a game-changer. Sadly, it wasn't. The Bose suspension system was a technological breakthrough. As you can see from the pair of Lexus LS sedans demonstrated (and the Porsche Cayman thrown in for good measure) in the two-minute video above from CNET, the system virtually eliminated body roll and smoothed out bumps in the road to near glass-like serenity. It could even jump over minor obstacles. Unfortunately, the system was too heavy and expensive to put into production, and the project was shelved. Instead, it was repackaged into a suspended driver's seat for heavy-duty, long-haul trucks and called the Bose Ride System. It's said to significantly reduce fatigue and back pain while encouraging driver alertness and wellness – which is all well and fine, but a far cry from what the suspension system could have meant for the automotive industry. Just think about that the next time you notice the Bose logo on the speaker grille in an upscale vehicle from the likes of Audi, FCA, GM, Mazda, or Nissan – all automakers that offer Bose audio systems, and which might have considered implementing the advanced suspension if only it were more practical for production.

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.

Lexus GS 300 disappears from 2020 lineup

The seven-strong Lexus GS lineup will enter 2020 with only five models in the lineup. Cars Direct found out the entry-level GS 300 will not ring in the new year, the discovery explained by a Lexus spokesperson with, "the GS 300 represented a small percentage of GS sales in 2018." That will leave the standard GS 350 and the GS 350 F Sport, both offered in either rear- or all-wheel drive. With the $47,885 GS 300 out of the game, the price of entry for the range goes up to $52,420 for the GS 350 RWD. That price represents a $150 increase over 2019, and an MSRP of $51,395 plus a $1,025 charge for destination and handling. Perhaps it's a sign of how much Lexus believes in the sport sedan credentials of the GS 350 that the rear-wheel-drive version currently on sale costs $330 more than the all-wheel-drive model. This is reversed for the F Sport trims, with the GS 350 F Sport AWD needing $1,745 more than version with a driven rear axle only. If pricing differentials hold across the range into 2020, that would make the GS 350 AWD $52,090, the GS 350 F Sport RWD would cost $53,785, and the GS 350 F Sport AWD $55,530. The GS F, charging along with a 5.0-liter V8 producing 467 horsepower and 389 pound-feet of torque sent to the rear wheels only, will run $86,035. That's a $560 bump over the 2019 model year. Since the GS F 10th Anniversary Edition celebrated the tenth anniversary of F performance this year, we don't expect the $89,350 sedan to continue into next year. The GS has been in the spotlight at Lexus HQ since last summer, when the brand's general manager told Automotive News "we're certainly evaluating both vehicles," speaking of the GS and IS. For next year, the 241-horsepower GS 300 slips off the scene, but one wonders how long even the 311-hp GS 350 can stick around when the entire lineup sold just 6,604 units in the U.S. last year. Sales are down more than 50 percent this year, down from a 2015 high of 23,117. The new ES is just nine horses down on the GS, $7,000 less expensive, and sold 50 percent more units in the U.S. in January than the GS has so far this year. With no news of an updated GS on the way and the ES rumored to add an all-wheel-drive trim for 2020, the GS could have a hard time standing up to business-case scrutiny.
