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.

What effect did Super Bowl ads have on online car searches?

Lexus's Super Bowl ad Let's Play starring an RC version of the RC 350 sliding around wasn't really a big hit among Autoblog readers, with a pretty miserable 13 down-votes as of this writing, compared to the winning Nissan spot with 52 up-votes. The Japanese luxury brand doesn't need to feel blue about the results, though, because in at least one metric the commercial ranks as the most popular of the night. According to Adweek analyzing figures from Kelley Blue Book, the Lexus coupe saw an astounding 1,820-percent increase in searches on the auto pricing site, more than any other vehicle advertised during the game. Viewers were apparently intrigued by the BMW i3 because the EV came in second place with a 1,131-percent jump. Third place went to the Mercedes-AMG GT with a 950-percent boost from its whimsical ad. The lowest growth for the night was from Toyota with a 20-percent upswing for the Camry. In terms of brand searches, the Kia James Bond-inspired spot brought a 68-percent increase in searches to KBB's website, according to Adweek. Dodge scored a close second with a 62-percent bump, and Fiat's humorous ad apparently resonated enough for third place and a 52-percent jump in searches. Despite the RC 350's popularity, Lexus actually ended up at the bottom of the list with just 6 percent more visitors looking for the company. To explain the weird discrepancy, a Kelley Blue Book analyst explained to Adweek that visitors came to the site specifically looking for the RC 350 and to a lesser extent the NX, which saw a 48-percent jump in queries, but that interest didn't extend to the whole brand.

2018 Lexus RX 450hL hybrid will start just over $50,000

Lexus has announced pricing on its 2018 RX 450hL, saying that its new three-row, all-wheel-drive hybrid crossover will carry a starting MSRP just $1,550 higher than the non-hybrid AWD RX 350L when it goes on sale starting in April. The RX 450hL will start at $51,615, positioning it right in-between luxury crossover competitors like the Mercedes-Benz GLE 350 and Infiniti QX60. The Luxury package, which adds features like semi-aniline trimmed seats, interior LED ambient lighting, laser-cut wood trim and 20-inch machine-finished alloy wheels, bumps the price up to $55,550. Prices include a $995 delivery, processing and handling fee. Lexus says the 450hL will get new features like second-row captain's chairs, leather-trimmed seats and complimentary Lexus Inform Safety Connect and Service Connect membership for the first 10 years of ownership. Standard safety features include a pre-collision system with pedestrian detection, lane-keep assistance, intelligent high beam headlights and all-speed dynamic radar cruise control. The RX 450hL combines a 3.5-liter V6 engine with two high-torque electric drive motor-generators to produce 308 in combined horsepower, with an EV mode allowing it to run on pure electric power at lower speeds for short periods. Lexus hasn't yet released fuel-economy figures for the hybrid, but the conventional RX 450h is rated at a combined 30 mpg by fueleconomy.gov. Lexus has added 4.3 inches to the rear body length of the 450hL and added more room for third-row occupants by incorporating a steeper tailgate. We've previously covered the introduction of the three-row RX 450hL and the 2018 RX 350L, which is powered by a 290-hp 3.5-liter V6 and is available in both front- and all-wheel-drive. The latter starts at $48,665 and goes up to $55,080. The RX line has been Lexus' best-selling model, with sales of 108,307 units in 2017.Related Video:
