2020 Cadillac CT5 vs 2021 Hyundai Sonata

The 2020 Cadillac CT5 was a striking representation of Cadillac's future design language, heavily inspired by the Escala concept vehicle. It exuded a sleek and elegant aesthetic, with a design that was largely free of flaws, save for a debatable chrome spear on the rear roof pillars. The standard 18-inch wheels complemented the car's proportions well, and the Red Obsession Tintcoat paint, though costly, added a touch of luxury. The CT5's interior, especially in the Premium Luxury trim with the Platinum Package, offered a high level of sophistication with premium semi-aniline leather and carbon-fiber accents, though some areas still showed room for improvement in material quality.

In contrast, the 2021 Hyundai Sonata presented a bold and distinctive design that was unmistakably a Sonata. The N Line variant enhanced this with functional and stylistic upgrades, such as larger air intakes and gloss black accents, which added to its sporty appeal. The interior of the Sonata N Line featured sport seats with Nappa leather and Dinamica suede, providing both comfort and support. The panoramic sunroof and high-quality materials contributed to a spacious and upscale feel, although the hard plastic seatback panels were a minor drawback for rear passengers.

The 2020 Cadillac CT5 offered a choice between an unrefined 2.0-liter turbocharged four-cylinder engine and a more powerful twin-turbo 3.0-liter V6. The latter, available in the Premium Luxury and standard in the CT5-V, delivered 335 horsepower and 400 pound-feet of torque, or 360 horsepower and 405 pound-feet in the CT5-V. Despite its impressive power, the V6's performance was occasionally marred by the 10-speed automatic transmission's unpredictable behavior during spirited driving. The CT5's suspension provided a comfortable ride, but its handling was less engaging at the limits, making it more suitable for relaxed driving.

The 2021 Hyundai Sonata N Line, equipped with a turbocharged 2.5-liter four-cylinder engine, produced 290 horsepower and 311 pound-feet of torque. Its eight-speed wet dual-clutch automatic transmission, combined with various driving modes, offered a dynamic driving experience. The Sonata N Line's sport-tuned suspension, larger brakes, and responsive steering made it a joy to drive on winding roads, while its front-wheel-drive layout managed to minimize understeer. The car's ride quality remained comfortable, and its fuel economy was reasonable given its performance capabilities.

The 2020 Cadillac CT5's interior benefited from a stretched wheelbase, providing ample space for both front and rear passengers. The Premium Luxury Platinum's front seats offered 18-way power adjustment and a range of comfort features, including lumbar massage and automatic climate controls. Rear passengers enjoyed generous legroom and air conditioning vents, while interior storage was practical and well-designed. However, the trunk space was limited to 11.9 cubic feet, with a non-flat floor and enclosed hinges.

The 2021 Hyundai Sonata N Line's interior was both comfortable and functional, with heated front sport seats that balanced support and comfort. Rear-seat accommodations were adequate, with rear air conditioning vents and a USB port enhancing passenger comfort. The Sonata's trunk offered a spacious 16 cubic feet of cargo space, with a 60/40-split folding rear seat for added versatility. The Smart Trunk hands-free release feature was a convenient addition, though the lack of an interior handle for closing the trunk was a minor inconvenience.

The 2020 Cadillac CT5 featured an updated Cadillac User Experience (CUE) infotainment system with a 10.0-inch touchscreen, offering Apple CarPlay, Android Auto, and a 4G LTE WiFi hotspot. The system was user-friendly, with physical controls and voice recognition that worked well. Optional upgrades included a navigation system and a 15-speaker Bose sound system. Additional technologies included a surround-view camera system, a rearview-camera mirror, and a head-up display, though the latter occasionally displayed incorrect speed-limit data.

The 2021 Hyundai Sonata N Line came equipped with a 12.3-inch digital instrumentation panel and a 10.25-inch touchscreen infotainment system. Standard features included navigation, wireless smartphone charging, and a Bose premium sound system. The system supported Apple CarPlay and Android Auto, though it lacked a WiFi hotspot. The absence of a tuning knob was a minor inconvenience, and the voice recognition system was not always reliable. The Sonata N Line also offered Hyundai Digital Key for Android devices and a calming Sounds of Nature feature.

The 2020 Cadillac CT5 offered a comprehensive suite of safety features, though many were only available on higher trims. The lane-keeping assistance system was subtle, sometimes leading to uncertainty about its operation. The adaptive cruise control system worked smoothly, maintaining safe distances and accelerating promptly. Super Cruise was not available for the 2020 model but was planned for 2021. The CT5 received five-star crash-test ratings from the NHTSA, though the IIHS had not rated it at the time of review.

The 2021 Hyundai Sonata N Line was equipped with Hyundai's SmartSense ADAS, including adaptive cruise control, forward-collision warning, and lane-keeping assistance. Additional features included Rear Occupant Alert, Safe Exit Warning, and Highway Drive Assist. The ADAS package was sophisticated and user-friendly, providing a stress-free driving experience. While the N Line had not been rated by the NHTSA or IIHS, the standard Sonata's high safety ratings suggested strong occupant protection.
