2021 Hyundai Sonata

Published on Mar 17, 2025 by Cassie Gould

Exterior Design: A Bold Statement

Hyundai has redefined the Sonata’s appearance with a sleek and sophisticated design. The 2021 Sonata features the brand's "Sensuous Sportiness" design philosophy, which emphasizes elegance and athleticism. The wide cascading grille gives the Sonata a commanding presence on the road. Flanked by slim LED headlights with a unique "hidden light" DRL design, the front end exudes modernity and sophistication. The coupe-like roofline flows seamlessly into the trunk, providing a premium and aerodynamic silhouette. Chrome accents along the window trim enhance the sedan's upscale appearance. A distinctive LED taillight bar spans the width of the trunk, adding a futuristic touch. The sculpted bumper and dual exhaust outlets (on certain trims) reinforce the sporty vibe. Buyers can choose from an array of vibrant colors, including Hampton Gray, Glowing Yellow, and Calypso Red, to personalize their Sonata.

Trims and Features

The 2021 Hyundai Sonata is available in five trims: SE, SEL, SEL Plus, N Line, and Limited. Each trim is carefully crafted to meet diverse customer needs, offering an ascending array of features and capabilities. SE, the base trim, includes a 2.5L 4-cylinder engine, 8-inch touchscreen, and standard safety features like adaptive cruise control and lane-keeping assist. SEL adds dual-zone climate control, heated front seats, and blind-spot monitoring. SEL Plus introduces a turbocharged engine, 19-inch alloy wheels, and wireless charging. The N Line offers a performance-focused 2.5L turbo engine, sport-tuned suspension, and distinctive styling cues. Limited trim features luxury appointments like leather upholstery, a 12.3-inch digital instrument cluster, and Bose premium audio.

Performance and Driving Experience

The 2021 Sonata offers three powertrain options tailored to different driving preferences. A 2.5L inline-4 engine powers the SE and SEL trims, delivering 191 horsepower and a smooth, efficient ride. The SEL Plus and Limited trims feature a 1.6L turbocharged engine with 180 horsepower, offering a blend of power and fuel efficiency. The N Line’s 2.5L turbocharged engine churns out 290 horsepower, transforming the Sonata into a sporty performer with sharp handling and robust acceleration. The Sonata’s ride quality balances comfort and agility, making it equally suitable for city commutes and highway cruising.

Interior: Technology Meets Comfort

Hyundai has elevated the Sonata's interior with premium materials, cutting-edge technology, and thoughtful design. The minimalist dashboard integrates a user-friendly touchscreen and digital controls, with soft-touch materials enhancing the cabin’s aesthetic. The Sonata’s seats are ergonomically designed for comfort, with available leather upholstery and ventilated options in higher trims. The base infotainment system includes an 8-inch touchscreen with Apple CarPlay and Android Auto, while higher trims feature a 10.25-inch display with navigation. The Bose premium audio system and features like wireless charging and a panoramic sunroof add to the luxury experience. With 16 cubic feet of trunk space and split-folding rear seats, the Sonata also excels in practicality.

Safety: Hyundai SmartSense

The 2021 Sonata boasts an impressive array of safety features under Hyundai’s SmartSense suite. Standard features include forward collision-avoidance assist, lane-following assist, and driver attention warning. Higher trims add advanced features like a blind-spot view monitor, rear cross-traffic collision-avoidance assist, and Remote Smart Parking Assist. Hyundai’s commitment to safety makes the Sonata a family-friendly choice and a top performer in safety ratings.

Fuel Efficiency and Cost of Ownership

With its efficient engines and competitive pricing, the 2021 Sonata is economical both at the pump and over its lifespan. The base 2.5L engine offers up to 38 mpg highway, while the turbocharged options maintain excellent efficiency. Hyundai’s 10-year/100,000-mile powertrain warranty adds significant value, complemented by a complimentary maintenance program covering basic services for the first three years or 36,000 miles. Routine maintenance costs remain affordable, contributing to the Sonata's appeal as a budget-friendly option.

Competition: How the Sonata Stacks Up

The 2021 Hyundai Sonata competes in a crowded midsize sedan market, standing out with its innovative design and tech-forward approach. The Toyota Camry remains a reliability leader, but the Sonata offers more modern features. The Honda Accord delivers a more engaging driving experience, but the Sonata N Line matches it in performance. The Nissan Altima’s optional all-wheel drive is a unique advantage, though the Sonata’s superior interior quality and advanced technology make it a more compelling choice for many buyers.

Customer Reviews and Market Perception

Owners of the 2021 Hyundai Sonata often praise its stylish design, tech-forward interior, and value for money. Positive feedback highlights the quiet and comfortable ride quality, intuitive infotainment system, and excellent warranty coverage. Some drivers have noted that the base engine could use more power for highway merging and passing, but this concern is addressed by the turbocharged options, particularly in the N Line trim.

Advanced Technology: Leading the Segment

The 2021 Hyundai Sonata is packed with advanced technology that elevates the driving experience. The Digital Key allows drivers to lock, unlock, and start the car using a smartphone, a feature not commonly found in competitors. The head-up display on higher trims projects critical driving information onto the windshield, minimizing distractions. Smart Cruise Control with Stop & Go adjusts the vehicle’s speed based on traffic conditions, enhancing convenience on long drives. The Sonata’s tech-savvy interior keeps drivers and passengers connected with multiple USB ports, voice recognition, and seamless smartphone integration.

Environmental Impact: Hybrid Options

For eco-conscious buyers, the Sonata Hybrid offers a compelling option. Its 2.0L hybrid engine delivers 192 combined horsepower while achieving up to 52 mpg in the Blue trim. A unique feature of the Sonata Hybrid is its solar panel roof, which helps charge the battery and increases driving range by adding approximately 2 miles of range per day in optimal conditions. The hybrid variant combines the Sonata’s innovative design with a commitment to sustainability, making it a strong contender in the hybrid sedan market.

Handling and Driving Dynamics

The Sonata delivers a composed and confident ride, with steering tuned for precision and responsiveness. The standard trims prioritize comfort, absorbing bumps with ease and offering a smooth driving experience. The N Line, however, introduces sport-tuned suspension and larger brakes, providing an engaging and dynamic performance that rivals some entry-level sports sedans. Whether you prefer relaxed cruising or spirited driving, the Sonata offers versatility to suit your needs.

Infotainment System Features

The infotainment system in the 2021 Sonata stands out for its user-friendly interface and customization options. The 10.25-inch touchscreen on higher trims features split-screen functionality, allowing users to display navigation, music, and other controls simultaneously. The voice recognition system has been enhanced for natural commands, making it easier to adjust settings without taking your hands off the wheel. Over-the-air updates ensure the system remains current, keeping the Sonata future-proof.

Build Quality and Materials

Hyundai has paid close attention to the Sonata’s build quality, using premium materials throughout the cabin. The fit and finish are impeccable, with minimal panel gaps and a solid feel that rivals luxury vehicles. Soft-touch surfaces and textured trim pieces enhance the interior’s tactile appeal, while available leather upholstery and ambient lighting create a premium ambiance. The exterior build also reflects Hyundai’s meticulous engineering, with excellent aerodynamics and durable paint finishes.

The 2021 Hyundai Sonata has earned recognition from various automotive organizations for its design, safety, and value. It received a Top Safety Pick designation from the IIHS, thanks to its comprehensive safety features and crash-test performance.
