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 North 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. | |
2021 Honda Accord Hybrid Reviews SummaryMidsize sedan buyers have never had it better. Across the boad, in one way or another, nearly every model is worthy of your consideration. But the 2021 Honda Accord is a standard-bearer in the segment, the car to beat in most respects. This year, Honda updates the 2021 Accord with a handful of changes intended to keep it at the top of its class and puts more emphasis on the hybrid version of the car, which is the subject of this review. | |

The 2021 Kia K5 represented a fresh chapter in Kia's design evolution, shedding its past image of drab sedans. With its fastback form and striking GT-Line trim, the K5 drew comparisons to the Audi A5 Sportback, thanks to the influence of Peter Schreyer, Kia's chief designer. The K5's exterior was a blend of sporty and sophisticated elements, featuring unique taillights and a killer front design with Z-shaped LED running lights. Inside, the K5's interior was driver-focused, with a split dash and quality materials, exuding a sense of sportiness and quality.
In contrast, the 2021 Honda Accord Hybrid was a testament to Honda's design prowess, boasting a well-proportioned and stylish exterior. The Accord received minor front styling updates, including a new grille and revised bumper, enhancing its overall appeal. The Touring trim featured new 19-inch aluminum alloy wheels, adding a touch of elegance. Inside, the Accord's cabin was remarkably upscale, with simulated matte-finish wood trim and polished metallic accents. The controls were logically arranged, and the infotainment system was user-friendly, making the Accord a pleasure to drive.















The 2021 Kia K5, despite its aggressive GT-Line styling, didn't quite deliver the sporty performance one might expect. The standard 1.6-litre turbo-four engine produced 180 horsepower and 195 lb-ft of torque, providing decent acceleration but lacking the punch for spirited driving. The GT trim promised more with a 2.5-litre turbocharged engine delivering 290 horsepower, but its front-wheel-drive setup raised concerns about handling. Fuel efficiency was commendable, with an estimated 8.2 L/100 km combined, making it a practical choice for daily commuting.
The 2021 Honda Accord Hybrid, on the other hand, featured a sophisticated two-motor hybrid system combining a 2.0-litre four-cylinder engine with an electric drive motor. This setup produced a combined 212 horsepower and 232 lb-ft of torque, offering quick acceleration and impressive fuel efficiency at 5.0 L/100 km combined. The Accord Hybrid's powertrain seamlessly switched between EV, Hybrid, and Engine Drive modes, providing a smooth and efficient driving experience. The Touring trim's 19-inch wheels and tuned suspension added to its athletic handling, making it a joy to drive.
The 2021 Kia K5 offered a comfortable interior with ample space for two adults in the back, despite its raked profile. The front seats were supportive, and the infotainment system was user-friendly, with an optional 10.25-inch display. However, the absence of rear air vents was a drawback. The K5's trunk provided 434 litres of space, accommodating most storage needs.
In contrast, the 2021 Honda Accord Hybrid excelled in interior space, offering a full-size sedan experience in a midsize package. The 12-way power-adjustable driver's seat and spacious back seat ensured comfort for all passengers. The Touring trim added heated and ventilated front seats and heated rear seats. Interior storage was generous, and the trunk boasted an impressive 473 litres, larger than any competitor in the segment, with 60/40 split-folding rear seats for added utility.
The 2021 Kia K5 featured wireless Apple CarPlay and Android Auto connectivity, making it easy to set up. Standard features included LED headlights, dual-zone climate control, and lane-keep assist. The GT-Line trim added 18-inch black alloys, a panoramic sunroof, and adaptive cruise control. The GT trim offered a Bose premium audio system and 19-inch wheels, enhancing the driving experience.
The 2021 Honda Accord Hybrid came with an 8-inch touchscreen infotainment system, Bluetooth, Apple CarPlay, and Android Auto as standard. The Touring trim included a head-up display, navigation, and wireless charging. While the voice recognition system required specific prompts, the overall technology package was comprehensive and user-friendly.
The 2021 Kia K5 earned top marks in crash tests, receiving the Top Safety Pick+ designation from the IIHS. It came equipped with a range of safety features, including forward collision avoidance assist, lane-keep assist, and blind-spot monitoring. The K5 EX trim and above featured Junction Turning for added safety at intersections.
The 2021 Honda Accord Hybrid aimed to improve its safety ratings by redesigning its LED headlights. Standard safety features included blind spot monitoring, rear cross-traffic alert, and Honda Sensing ADAS. The Touring trim added low-speed braking control and automatic emergency braking. While the Honda Sensing system showed improvements, some aspects, like lane departure warning, needed refinement.
