2020 Cadillac CT5 Reviews SummarySince its debut nearly 20 years ago, the Cadillac CTS has enjoyed praise from critics and consumers alike. At the height of the car’s popularity, it came in sedan, coupe, and wagon body styles, all three available in high-powered, performance-tuned CTS-V variants—with manual transmissions. Those days are over because y’all want SUVs and can’t use a clutch pedal. Still, Cadillac thinks there is life left in luxury cars. The new 2020 Cadillac CT5 replaces the CTS in the company’s lineup, and though based on the previous CTS' Alpha platform, it’s an entirely different car that deserves your consideration. | |
2021 Kia K5 Reviews SummarySedans are now the most exciting new cars in the mainstream market. They are to crossovers today what craft beer was in the early 2000s. They’re not on every corner anymore because Americans prefer trucks over cars, but sedans like the 2021 Kia K5 are refreshing to see, surprisingly good to drive, and will make you look cultured and smart without having to try. The K5—and its new name—replaces the Optima and upgrades nearly everything in the pursuit of style and performance. It’s one of the best midsize sedans out there. | |

The 2020 Cadillac CT5 was a striking representation of Cadillac's future design language, heavily inspired by the Escala concept vehicle. Its sleek and elegant appearance was marred only by a minor design quibble: a chrome spear extending too far back on the rear roof pillars, which visually shortened the car. Despite this, the CT5 maintained a harmonious balance in its lines and proportions, a feat not achieved by its predecessor, the CTS. The standard 18-inch wheels complemented the car's design without appearing undersized, and the optional Red Obsession Tintcoat paint, though costly, added a touch of luxury.
Inside, the CT5's Premium Luxury trim offered a sophisticated cabin with premium semi-aniline leather and carbon-fiber accents, creating an exclusive atmosphere. The quality of materials was superior to the smaller CT4, though some areas, like the lower door panels, could have been improved. The CT5's cabin provided a sense of luxury and comfort, with features like a lumbar massage function and automatic climate controls enhancing the driving experience. Overall, the CT5 delivered a compelling blend of style and substance, making it a serious contender in the midsize luxury sedan segment.
The 2021 Kia K5 marked a significant departure from Kia's past, showcasing a bold new identity with its fastback sedan design. Styled in the GT-Line trim, the K5 resembled an Audi A5 Sportback, thanks to the influence of Peter Schreyer, Kia's chief designer. The K5's design was characterized by its long, ovoid-shaped rear window, unique taillights, and a striking front end with Z-shaped LED running lights. Despite some fake air vents and exhaust tips, the K5's proportions and details contributed to a sporty and appealing appearance.
Inside, the K5's interior was designed with both style and functionality in mind. The dash was split between driver and passenger, with a Supra-style divider and an angled center stack. The GT-Line featured red seats with black accents and a flat-bottom steering wheel, adding to the sporty feel. The materials used throughout the cabin were of high quality, with padded surfaces and well-executed details. The K5's interior exuded a sense of sportiness and quality, setting it apart from many of its competitors.
















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 on the Premium Luxury and standard on the CT5-V, delivered 335 horsepower and 400 pound-feet of torque in the Premium Luxury trim, and 360 horsepower and 405 pound-feet of torque in the CT5-V. Both engines were paired with a 10-speed automatic transmission, featuring paddle shifters and Active Fuel Management for improved fuel economy. The V6 transformed the CT5 into a powerful and exhilarating sedan, though the transmission's behavior in Sport mode could be unpredictable, affecting the driving experience.
The CT5's suspension was tuned for comfort, providing a smooth ride over real-world road conditions. The rack-mounted electric steering and well-calibrated brake pedal contributed to a confident driving experience, though the all-season tires limited the car's performance potential. Overall, the CT5 was most enjoyable when driven up to 8/10ths of its limits, with the CT5-V offering a more engaging experience for those seeking higher performance.
The 2021 Kia K5, particularly in the GT-Line trim, did not deliver the sporty performance suggested by its aggressive styling. The standard 1.6-liter turbo-four engine produced 180 horsepower and 195 pound-feet of torque, providing adequate performance for everyday driving. The eight-speed automatic transmission was responsive, though not always smooth. The K5's ride was balanced and isolated, with good brakes and communicative steering, but the GT-Line's handling fell short of expectations.
The GT trim promised a more powerful 2.5-liter turbocharged engine with 290 horsepower and 311 pound-feet of torque, though it was only available with front-wheel drive. The K5's fuel economy was impressive, with an EPA-estimated 31 mpg combined for front-wheel-drive models. While the K5 excelled as a family sedan, its sporty trim did not fully live up to the hype.
The 2020 Cadillac CT5's interior was a significant improvement over the previous CTS, offering true midsize spaciousness. The Premium Luxury Platinum's front seats provided 18-way power adjustment, lumbar massage, and automatic climate controls, ensuring all-day comfort. The rear seat offered ample legroom and a comfortable cushion, thanks to the stretched wheelbase. Interior storage was generous, with a smartphone tray, large glove compartment, and door-panel bins. However, the trunk space was limited to 11.9 cubic feet, with a non-flat floor and enclosed hinges.
The 2021 Kia K5's interior was designed to accommodate two adults comfortably in the rear, despite its raked profile. The front seats were supportive and firm, ideal for long drives. The K5's infotainment system was user-friendly, with hard buttons for climate controls and a convenient wireless charging pad. The trunk offered 16 cubic feet of space, with the option to fold down the rear seats for additional storage.
The 2020 Cadillac CT5 featured an updated Cadillac User Experience (CUE) infotainment system, with a 10.0-inch high-definition touchscreen, stereo knobs, and piano-key controls. The system included Apple CarPlay, Android Auto, a 4G LTE WiFi hotspot, and Near Field Communication for easy smartphone pairing. Optional upgrades included a navigation system and a 15-speaker Bose sound system. The CT5 also offered a surround-view camera system, rearview-camera mirror, and parking assist with automatic emergency braking. A head-up display was available, though its speed-limit data was occasionally inaccurate.
The 2021 Kia K5 came standard with wireless Apple CarPlay and Android Auto, making it easy to set up. The GT-Line trim added features like fog lights, rear USB ports, and a power driver's seat. The Premium package included a panoramic sunroof, adaptive cruise control, and LED headlights. The EX trim offered heated and ventilated seats, a Bose stereo system, and a 10-inch infotainment display. The GT trim added paddle shifters and performance hardware, with the infotainment system offering unique voice command features.
The 2020 Cadillac CT5 boasted a sophisticated safety-technology suite, with features like lane-keeping assistance, adaptive cruise control, and a Safety Alert driver's seat. The CT5 earned five-star crash-test ratings from the NHTSA, though the IIHS had not rated it at the time of review. Super Cruise, Cadillac's hands-free driver-assist technology, was not available for the 2020 model.
The 2021 Kia K5 was too new to be rated by the NHTSA or IIHS, but it was expected to receive top scores due to its strong chassis and body shell. Standard safety features included rear side airbags, forward emergency braking, lane-keep assist, and a driver attention monitor. Higher trims offered additional features like blind-spot monitoring, rear emergency braking, and parking sensors.
