To be honest, maybe this IS is just a guinea pig (like others have said, a refreshed exterior and some changes in dimensions to keep cost to a minimum) and a showcase of what is to come. I still think torque vectoring (like in the RCF or GSF) is something many enthusiasts would want and Toyota is trailing Honda's SH-AWD, at least from the impression I gathered.
Can't wait for what's to come after this 3.3IS, it better not be a 3.4IS haha.
Sorry for the high school student-like highlights lol.

The Lexus Driving Signature Lives at Shimoyama
From day one, the IS has left a lasting impression in the luxury sports sedan segment, where dynamic capability and driving performance are mandatory attributes. The 2021 IS looks to further cement the bond between driver and vehicle by providing an enhanced linear driving characteristic that provides clear and direct feedback to the driver. In order to achieve this objective, Lexus engineers needed the proper tool with which to hone the vehicle’s skills.
Enter the Toyota Technical Centre Shimoyama. More than merely a new test facility, this asphalt track
signals a change in Lexus’ product development course and speaks to the brand’s commitment to its human-centred nature.
Since Lexus launched, the tactile feel, behavior, and execution for each model has been driven by the vision and efforts of the Chief Engineer.
Moving forward, the efforts of the CE will be focused on elevating the vehicles to a new standard of performance and handling as developed by Lexus International President Koji Sato and Chief Branding officer Akio Toyoda. T
he ultimate goal is to deliver a new generation of Lexus vehicles that is more balanced, refined in control, and confident than ever before. Linear steering, brake responses, and optimized handling with exceptional ride quality is the result of heightened focus on tuning of the chassis and its interactions with the control surfaces through diligent evaluation at a test facility unlike any other.
By establishing a uniform Lexus Driving Signature across the entire lineup, the hope is to continue propelling the brand’s evolution and reinforce its identity in the luxury space. This cultural shift within Lexus product development builds on the learnings and improvements seen on the F brand cars, and the latest models of the flagship vehicles (LC, LS, LX) that involve an “Always On” philosophy for continual, running enhancement. Over the past 30 years, Lexus has been defined by the detail-oriented and thoughtful nature of its products.
The latest IS represents the first step down a path that has evolved into a uniquely Lexus tarmac testbed that will affect the trajectory of every Lexus product that comes next.
“What we had foremost in mind in developing the new IS was to make it a car that excelled in communicating with the driver regardless of the road conditions or driving situation,” said Chief Engineer Naoki Kobayashi of Lexus International. “We aimed to make the new IS a Lexus luxury sports sedan that provides high-quality riding comfort while offering a high level of vehicle control.”
Opened in 2019, the Toyota Technical Centre Shimoyama in Japan’s Aichi Prefecture is near Lexus’s global headquarters. Its country road test course is inspired by Lexus’s many years of experience driving on Germany’s Nürburgring Nordschleife, famous throughout the world for its grueling driving conditions. Much like the IS itself, Nürburgring is near and dear to Akio Toyoda’s heart since it played a key role in his quest to become a master driver. The approximate 5.3-kilometer test course at Shimoyama is designed to take advantage of the local topography, and it features a nearly 75-meter change in elevation, a wide range of curves and corners, and multiple types of road surfaces. Developing the new IS in such a severe driving environment made it possible to infuse an ever-higher dimension of vehicle performance.
