The 2021 Hyundai Sonata Hybrid, a continuation of the bold design introduced in the 2020 model year, stood out in the sedan market with its aggressive styling. Despite some comparisons to the Honda Accord Hybrid and Camry Hybrid, the Sonata Hybrid's unique exterior, featuring a matte gray paint scheme and aerodynamic details, made it a distinctive choice. Inside, the cabin offered a mix of modern technology and comfort, with logically placed controls and supportive seating, ensuring a pleasant experience for both front and rear passengers.
In contrast, the 2021 Lexus IS presented an athletic and elegant design, capturing a sense of motion even when stationary. Its exterior featured a new spindle grille, narrow headlights, and a fast roofline, contributing to its sporty appearance. The interior matched this boldness with a simple yet modern aesthetic, though the analog clock felt outdated. The IS's design emphasized quality and style, appealing to those seeking a luxury sports sedan with a strong visual statement.
















The 2021 Hyundai Sonata Hybrid was equipped with a 2.0-liter four-cylinder engine paired with an electric motor, delivering a combined 192 horsepower through a six-speed automatic transmission. The Limited trim featured a solar panel roof, adding approximately two miles per day to its range. The Sonata Hybrid offered solid acceleration and a smooth transition between battery and engine power, with multiple drive modes to suit different driving styles. Its refined driving dynamics, precise steering, and effective braking made it a competent choice for hybrid enthusiasts.
The 2021 Lexus IS, designed with the "Lexus Driving Signature," offered a range of powertrains. The IS 300 RWD featured a 2.0-liter turbocharged engine with 241 horsepower, while the AWD version had a 3.5-liter V6 producing 260 horsepower. The IS 350 models, both RWD and AWD, boasted a 311-horsepower V6. With a top speed of 143 mph and 0-60 mph times ranging from 6.9 to 5.6 seconds, the IS delivered impressive performance. Its balanced weight distribution, independent suspension, and precise steering contributed to a dynamic driving experience, though fuel efficiency varied across models.
The 2021 Hyundai Sonata Hybrid offered a spacious interior with 16 cubic feet of trunk space, making it one of the larger options among midsize hybrid sedans. The cabin provided ample legroom for front passengers and decent rear-seat space, though the sloping roofline required some maneuvering to enter. Storage options included door pockets, a center console, and a wireless charging pad, ensuring convenience for everyday use.
The 2021 Lexus IS focused on driver comfort with an easily adjustable seating position and supportive seats, especially in the F Sport trim. The interior featured NuLuxe upholstery, offering a leather-like feel without the maintenance. Storage was ample, with various compartments and cupholders, though rear-seat space was limited for three passengers. The trunk, at 10.8 cubic feet, was deep but smaller than the Sonata's, reflecting its compact sedan status.
The 2021 Hyundai Sonata Hybrid came with an 8-inch touchscreen, upgraded to a 10.25-inch screen with navigation in the Limited trim. Standard Apple CarPlay and Android Auto integration allowed for seamless connectivity, though CarPlay only occupied part of the larger screen. The intuitive layout, wireless charging pad, and head-up display added to the tech-savvy appeal, despite some limitations for taller drivers.
The 2021 Lexus IS introduced a touchscreen infotainment system with Android Auto and Apple CarPlay, alongside a touchpad for navigation. Lexus Enform services offered various connected features, with trial subscriptions for safety, service, and remote access. The optional Mark Levinson audio system provided exceptional sound quality, appealing to audiophiles. However, the subscription model for navigation and other features could be a concern for long-term ownership.
The 2021 Hyundai Sonata Hybrid was equipped with a comprehensive suite of driver-assistance features, including forward-collision avoidance, lane-departure warning, and adaptive cruise control. The Limited trim added a head-up display and parking sensors. The Sonata Hybrid earned top safety ratings from the IIHS and NHTSA, ensuring peace of mind for drivers.
The 2021 Lexus IS featured the Lexus Safety System+ 2.5, offering advanced safety technologies such as pedestrian detection, lane-departure warning, and adaptive cruise control. Additional features included blind-spot monitoring, a backup camera, and LED lighting. While official safety ratings were not yet available, the IS was expected to perform well based on its platform and equipment.
