With competitive safety, technology, and fuel efficiency now supplemented by an attractive exterior and interior design, the Sentra no longer feels like a compromise—it feels like a smart choice. | |
2022 Kia K5 Reviews SummaryLast model year, as part of a redesign of its midsize sedan, Kia changed the car’s name from Optima to K5. Rakishly attractive and an undeniably good value, the new Kia K5 is an appealing choice in a shrinking vehicle segment where it faces fewer rivals with each year that passes. For the 2022 model year, the K5 wears Kia’s redesigned emblems and upper trim levels add standard features. | |

The 2021 Nissan Sentra, in its eighth generation, presented a compact four-door sedan with a sporty and athletic exterior. It featured a V-Motion grille and expressive headlights, giving it a bold and serious look. The Sentra offered a variety of paint colours, including two-tone options for the SR trim, enhancing its visual appeal. Inside, the Sentra boasted a spacious and well-designed interior with an 8-inch infotainment touchscreen, textured plastics, and a flat-bottomed steering wheel. The second row provided ample space for two passengers, and the trunk offered 404 litres of cargo capacity, with a 60/40 split-folding rear seat for added versatility.
The 2022 Kia K5, available in various trims, showcased a sleek and luxurious design, resembling a sports sedan. It featured a low, long profile with a distinctive style. The interior exuded quality, with a combination of synthetic leather, matte-finish trim, and metallic accents. The K5's controls conveyed a sense of solidity, and the cabin was well-insulated from wind noise. However, road noise and suspension issues affected ride quality. The K5's design and build quality made it feel like a premium vehicle, offering a unique and upscale experience.














The 2021 Nissan Sentra was equipped with a 2.0-litre naturally aspirated four-cylinder engine, producing 149 horsepower and 146 pound-feet of torque. It featured front-wheel drive with an Xtronic CVT, providing adequate performance for daily commuting. The Sentra's lightweight design contributed to its efficiency, with fuel consumption ratings of 8.0 L/100 km city and 6.0 L/100 km highway for S and SV models. The suspension and steering offered tidy road manners, making it a practical choice for urban driving.
The 2022 Kia K5 offered a more powerful option with its GT trim, featuring a turbocharged 2.5-litre engine delivering 290 horsepower and 311 pound-feet of torque. However, the GT lacked all-wheel drive and was less fuel-efficient. The standard 1.6-litre turbocharged engine provided 180 horsepower and 195 pound-feet of torque, offering linear power delivery and decent performance. The K5's fuel economy was rated at 8.2 L/100 km combined. While the K5 excelled in highway driving, it struggled with road noise and suspension issues on uneven surfaces.
The 2021 Nissan Sentra's interior was well-organized, with features like a traditional gear selector, open cupholders, and ample storage space. It included USB ports and a 12-volt outlet for connectivity. The Zero Gravity front seats provided comfort for long journeys, and heated front seats were standard. The SR Premium trim offered additional features like a power-adjustable driver's seat and a moonroof.
The 2022 Kia K5 prioritized comfort with dual-zone climate control, power-adjustable seats, and a panoramic sunroof. The interior featured SynTex synthetic leather and ample rear-seat space. The K5's controls were logically arranged, and storage options were generous, including a spacious trunk with a 434-litre capacity. However, the low-slung design made entry and exit challenging for some.
The 2021 Nissan Sentra offered a straightforward infotainment system with a 7-inch touchscreen in the S trim and an 8-inch touchscreen in SV and SR trims. It included Apple CarPlay, Android Auto, and Bluetooth connectivity. The SR Premium trim featured a premium Bose audio system. Navigation was not available, but smartphone integration provided access to navigation apps.
The 2022 Kia K5 featured two infotainment systems, with an 8-inch touchscreen in lower trims and a 10.25-inch touchscreen in higher trims. The larger screen required a cable for smartphone integration but offered satellite radio, navigation, and Kia Connect services. A wireless smartphone charger was standard on most trims, and the GT trim boasted a 12-speaker Bose audio system. However, the voice recognition system was subpar.
The 2021 Nissan Sentra came equipped with a comprehensive suite of safety features, including multiple airbags, a tire pressure monitoring system, and Nissan Safety Shield 360. It received a five-star overall rating from the NHTSA and a Top Safety Pick rating from the IIHS. The Sentra's adaptive cruise control and 360-degree camera system were available on higher trims.
The 2022 Kia K5 excelled in safety with features like forward-collision-avoidance assist, blind-spot monitoring, and lane-keeping assist. It also offered advanced systems like Safe Exit Assist and Highway Driving Assist. The K5 achieved a Top Safety Pick+ rating from the IIHS and a five-star rating from the NHTSA. Its safety technology was highly effective, providing peace of mind for drivers.
