2021 Hyundai Sonata Hybrid vs 2022 Mercedes-Benz C-Class

The 2021 Hyundai Sonata Hybrid was a bold entry in the midsize sedan market, carrying over its striking design from the previous model year. Its exterior styling was distinctive, with a matte gray paint scheme and aerodynamic features like an integrated deck-lid spoiler and taillight strakes. While some found its catfish-like appearance polarizing, it certainly stood out. Inside, the Sonata Hybrid offered a more conventional yet refined cabin, featuring soft-touch surfaces and a modern haptic bezel surrounding the vivid touchscreen infotainment system. The seats were comfortable and supportive, making long trips enjoyable for both front and rear passengers.

In contrast, the 2022 Mercedes-Benz C-Class showcased a cohesive design that borrowed elements from other Mercedes models, resulting in a stylish sedan recognizable from any angle. Its cab-rearward proportions emphasized its rear-wheel-drive platform, distinguishing it from front-wheel-drive models like the CLA-Class. The C-Class featured standard LED headlights and taillights, with an optional Digital Light system for enhanced visibility. Inside, the C-Class aimed to emulate the luxury of the S-Class, with a freestanding touchscreen, intricate speaker grilles, and ambient lighting. Despite its luxury billing, the standard upholstery was synthetic leather, with Nappa leather available on higher trims.

The 2021 Hyundai Sonata Hybrid was powered by a 2.0-liter four-cylinder engine paired with an electric motor, delivering a combined 192 horsepower to the front wheels via a six-speed automatic transmission. The Limited trim featured a solar panel roof, adding about two miles per day to its driving range. The Sonata Hybrid offered solid acceleration, with a Drive Mode toggle allowing drivers to switch between Eco, Sport, Custom, and Smart modes. The transition between battery-only and engine power was seamless, and the auto stop-start system was minimally intrusive. The Sonata Hybrid impressed with its refined driving dynamics, light yet precise steering, and solid braking performance.

The 2022 Mercedes-Benz C-Class C300 was equipped with a 2.0-liter turbocharged four-cylinder engine, producing 255 horsepower and 295 pound-feet of torque. It featured a nine-speed automatic transmission and a 48-volt mild-hybrid system, contributing up to 20 hp and 148 lb-ft of torque in short bursts. The C300 accelerated from zero to 60 mph in 5.9 seconds, with a top speed of 130 mph. While the powertrain was powerful, it exhibited turbo lag and occasional rough shifts. The ride quality was luxurious, with muted impacts over bumps, though some vibration was noted. The C-Class handled well on twisty roads, offering good body control and precise steering, though it required a deliberate approach to cornering.

The 2021 Hyundai Sonata Hybrid offered 16 cubic feet of trunk space, one of the largest among midsize hybrid sedans. The cabin provided ample legroom for front passengers and decent rear-seat space, accommodating four adults comfortably. However, the sloping roofline resulted in a low rear door opening, requiring occupants to lower their heads when entering. Front passengers had access to cargo pockets and a center console, with a wireless charging pad in the Limited trim.

The 2022 Mercedes-Benz C-Class sedan was longer and wider than its predecessor, offering increased interior space. It led its class in front-seat headroom and rear-seat legroom, though front legroom was less generous. The seats were comfortable with adequate bolstering, and forward visibility was excellent. However, thick rear pillars created blind spots, necessitating the use of driver aids. The trunk offered 17.9 cubic feet of space, with a wide opening for easy loading. A split-folding rear bench accommodated longer items, though cargo space with the seat folded was not specified.

The 2021 Hyundai Sonata Hybrid came standard with an 8-inch touchscreen infotainment system, with a 10.25-inch screen available on the Limited trim. It featured Apple CarPlay and Android Auto, though CarPlay only occupied two-thirds of the larger screen. The layout was intuitive, with crisp graphics and a traditional volume knob. The Limited trim included a wireless charging pad and a head-up display, though the HUD's adjustability was limited for taller drivers.

The 2022 Mercedes-Benz C-Class featured an infotainment system inspired by the S-Class, with a 12.3-inch digital instrument cluster and an 11.9-inch touchscreen angled toward the driver. Wireless Apple CarPlay and Android Auto were standard, with a Burmester 3D surround-sound system available on higher trims. The MBUX system offered a "Zero Layer" setup, displaying multiple functions on the screen simultaneously. The voice recognition system was highly effective, and touch controls on the steering wheel were easy to use. The optional augmented-reality navigation system provided helpful visual cues for turns.

The 2021 Hyundai Sonata Hybrid came standard 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, 360-degree parking monitor, and parking sensors. The Sonata Hybrid earned a five-star overall safety rating from the NHTSA and was a 2021 IIHS Top Safety Pick.

The 2022 Mercedes-Benz C-Class offered a range of advanced driver assistance systems, with many features standard. These included automatic emergency braking, blind-spot monitoring, and Pre-Safe systems. Optional features included lane-keep assist, a 360-degree camera system, and adaptive cruise control.
