Lexus wants to be neck on neck with BMW in the medium segment and is readying the new IS model. The new 2021 Lexus IS was unveiled today via a unique and engaging online virtual reveal. Since its debut nearly 20 years ago in the U.S., the IS has thrived on creating exhilarating driving performance in the form of a true rear-wheel-drive luxury sports sedan.
One of the first things engineers targeted was enhancing body rigidity. This was done in key areas such as reinforcing the radiator side supports, increasing the number of front-side-member weld points, and optimizing reinforcement structures from the C-pillars to the sides of the roof. The increased rigidity not only helps reduce unwanted noise and vibration, but it also helps improve riding comfort and driving performance with enhanced response to steering input.
For the first time, the new IS will be available with larger 19-inch wheels to improve cornering force and provide a greater contact patch with the road. Engineers revised the suspension layout and front pickup points to help accommodate the larger tire-and-wheel package. Overall two different 19-inch wheels are available on F SPORT models, including a unique BBS wheel specific to the F SPORTs equipped with the Dynamic Handling Package. Standard 18-inch wheels will replace the outgoing 17-inch wheels on all other models.
Taking a cue from the Lexus LFA supercar, engineers took rigidity enhancements one step further by employing lighter weight hub bolts to secure each wheel to the new IS. The use of hub bolts allows for improved fastening strength and therefore an increase to rigidity to further enhance braking and handling. What’s more, the move to hub bolts sheds approximately 2 pounds of total unsprung weight. The new bolts also feature a black coating so as not to draw any attention away from the attractive new wheel designs.
Complementing the enhancements to overall rigidity, multiple refinements were made to the suspension setup. For starters, engineers targeted a reduction in unsprung weight. The new IS features coil springs that are 20 percent lighter than the outgoing model. New A-arms are employed as well that feature a forged aluminum material versus the outgoing steel composition, resulting in an 18 percent weight reduction. Engineers also opted for a new material for the suspension stabilizer bar to optimize the diameter and thickness to provide a 17 percent weight reduction.
The IS F SPORT lineup is restructured in the 2021 model year, as F SPORTs will only be offered on the IS 350 powered by the 311-horsepower 3.5-liter V6 engine. F SPORT features a host of visual and performance cues that immediately set it apart, including a unique front bumper with functional aerodynamic enhancements, rear bumper, grille surround, rear lip spoiler, rocker molding and more. Along with F SPORT 19-inch wheels, a unique center cap and larger rear tires for added performance (265/35R19), they are also equipped with a cool air intake with sound generator and an F SPORT exhaust and diffuser. In addition, unique F SPORT badges adorn the sides and rear of the vehicle as well.
Inside the new IS, stainless-steel scuff plates adorn the door sills. Eyes are immediately drawn to the stylish F SPORT front seats, especially when dressed in the available new Circuit Red option. The front seats also offer standard heated and ventilated functions. A heated leather-wrapped steering wheel with unique center ornament, perforated leather-wrapped shifter and F SPORT combination instrumentation meter await the driver, as do unique F SPORT accelerator pedal, brake pedal and footrest. The distinctive front seats offer available two-way power adjustable lumbar support as well as four-way adjustable headrests. Unique F SPORT door accents are highlighted with black geometric film window switch surrounds. Active Sound Control has been improved to further enhance the exhilarating performance notes of the V6 engine while reducing unpleasant tones.
F SPORT models can be further augmented with the addition of a Dynamic Handling Package (DHP) that includes Adaptive Variable Suspension (AVS). For 2021, engineers have optimized the damping force of the AVS system to help enhance performance. In addition, the DHP also includes lighter 19-inch forged alloy BBS wheels finished in matte black. Not only are they impressive looking, the 19-inch BBS wheels are approximately 4 pounds lighter per wheel compared to the standard 19-inch F SPORT wheel.
New trim adorns each door in F SPORT models with a graphic pattern of embossed intersecting lines, representing a new form of Lexus decorative expression and Takumi craftsmanship. Decorative ornamentation is finished for the first time in Black Metallic paint, Black Geometic Film, or the unique Ash ornamentation exclusive to F SPORT models equipped with the Dynamic Handling Package. Piano Black accents also can be found on surface elements for cabin atmosphere that is both dignified and sporty. Standard NuLuxe interior color options include Black, Glazed Caramel and Rioja Red. On F SPORT packages the options include Black, Circuit Red, and two-tone White/Black, while the F SPORT Dynamic Handling Package is available in Black or Circuit Red interior.
The 2021 IS will be available in both rear- and all-wheel drive options, and there are three distinct powertrain options available depending upon the grade.
The rear-wheel drive IS 300 features a 2.0-liter, turbocharged and intercooled inline four-cylinder engine. The 2.0-liter engine is updated for 2021, featuring an adaptive transmission control that helps determines the most appropriate gear for each driving situation based on driver input to achieve linear response. Rated to deliver 241 horsepower, the stout four-cylinder also produces a solid 258 lb-ft of torque across a flat torque range from 1 ,650 rpm all the way up to 4,400 rpm. It’s not only powerful, it’s efficient, too, thanks to a sophisticated Variable Valve Timing intelligent – Wide (VVTi-W) system which allows the engine to switch between the Otto and Atkinson combustion cycles to maximize efficiency. It comes equipped with an eight-speed Sport Direct Shift (SPDS) automatic transmission. It integrates an advanced G-force Artificial Intelligence (G-AI) system that monitors multiple performance parameters to determine the optimum gear selection.
For added traction in cold-weather climates, the IS 300 is also available with all-wheel drive. The IS 300 AWD is powered by a 3.5-liter V6 that delivers 260 hp and 236 lb.-ft. of torque to all four wheels through a six-speed automatic transmission. The electronically controlled all-wheel drive system is designed to help enhance traction and grip by automatically varying front-to-rear torque distribution. On dry roads it maintains a 30:70 front-to-rear torque split for maximum performance, but it’s capable of sending as much as 50 percent of the power to the front wheels in certain conditions.
For buyers who crave maximum power, there’s the IS 350 in either rear-wheel drive or all-wheel drive powered by a 3.5-liter V6 that produces 311 hp and 280 lb.-ft. of peak torque. The rear-wheel drive model uses the same eight-speed Sport Direct Shift automatic transmission found in the IS 300 RWD, while the AWD version sends power through a six-speed automatic. If there’s any question about the performance-minded nature of each vehicle, look no further than their 0-60 times, as the IS 350 RWD covers the ground in 5.6 seconds while the IS 350 AWD goes from 0-60 mph in 5.7 seconds.
