2021 Lexus IS debuts with new styling and greater emphasis on handling

The reveals keep on coming today. Lexus just took the wraps off the 2021 Lexus IS sport sedan, the fourth generation of its small, sporty four-door. It may not look all that different on the outside, but Lexus is making heady claims that the driving experience is going to be the real head turner. We’ll start with the looks, though. Lexus has only revealed the 2021 IS in F Sport trim, which is the most aggressive of all the models. The spindle grille again sits proudly in front. (Apparently, even non F Sport models have mini spindles within the grille design, so we hope you like spindles.) YouÂ’ll also see a new air intake below that grille. ItÂ’s meant to direct air to the brakes and assist in cooling. The slimmer headlights with a new LED pattern look sharp. Along the side, Lexus has implemented new rocker panels that kick up into the rear fender for a more aggressive stance. The view from the rear offers up the most noticeable change. Lexus has gone with the full-width taillight design, stretching the red element from one side of the trunk to the other. Those taillights feature more intricate sculpting, and the rear valance is finished in a glossy black. Lexus changed the exhaust tip look, too, opting for ovals this time. But, onwards to the performance. The powertrain lineup hasnÂ’t changed a bit. A Lexus IS 300 with rear-wheel drive continues to be powered by a 2.0-liter turbocharged four-cylinder. It makes the same 241 horsepower and 258 pound-feet of torque as before, and is mated to an eight-speed automatic transmission only. However, Lexus says itÂ’s been updated for “adaptive transmission control” that is better at choosing the appropriate gear for the driving situation. An all-wheel-drive IS 300 is also available, but itÂ’s equipped with the 3.5-liter V6 that makes 260 horsepower and 236 pound-feet of torque. The all-wheel-drive IS 300 is also continuing to send the power through a six-speed automatic transmission exclusively. The system can send as much as 50% of torque to the front axle. The tip-top IS is the IS 350. ItÂ’s equipped with a 3.5-liter V6 that makes 311 horsepower and 280 pound-feet of torque. With rear-wheel drive, itÂ’s equipped with an eight-speed automatic, but the all-wheel-drive version is equipped with a six-speed auto. Lexus says the rear-drive IS 350 will get to 60 mph in 5.6 seconds, while the all-wheel-drive car gets there in 5.7 seconds.

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.
