Mercedes-Benz GLS vs Hyundai Ioniq 5

The 2026 Hyundai Ioniq 5 combined the retro charm of a 1980s hatchback with the modern flair of a crossover SUV, creating a unique aesthetic that surprisingly worked well. Its profile was distinctly hatchback-like, yet larger than typical models like the Volkswagen GTI or Toyota Corolla. Angular lines and a character line rising from the rear wheels to the front doors formed a triangular shape that defined its profile. Dark cladding around the wheels and lower body added a crossover touch. The front featured a visor slit with rectangular headlights and a small grille in a darkened fascia, while the rear boasted an integrated spoiler and rectangular taillights. The XRT model stood out with unique 18-inch alloys, dark trim, and pixel-patterned cladding, giving it a rally car vibe.

Inside, the Ioniq 5 leaned towards a utilitarian design with a strong emphasis on technology. The base model featured standard cloth upholstery, while higher trims offered synthetic leather, maintaining a rather cold theme with only black and gray options. The tech setup included dual 12.3-inch screens and touch controls for the climate system, contributing to a sterile yet modern EV interior.

The 2027 Mercedes-Benz GLS, retaining its third-generation design, underwent significant updates for a more striking appearance. The new front end featured headlights with three-pointed star elements and a grille adorned with miniature stars, creating a galaxy-like effect. The rear echoed this motif with new taillights set into a one-piece panel. The GLS 450 and GLS 580 models offered six-cylinder and V8 engines, respectively, with the AMG GLS 63 and Maybach GLS 680 providing performance and luxury options. The facelifted model, while more ostentatious, ensured it wouldn't be overshadowed by competitors like the Escalade or Range Rover.

Inside, the GLS featured a bold Superscreen display spanning the dashboard, though it lacked charm. The interior maintained its high level of fit and finish, with ambient lighting enhancing the cabin's appeal. Standard leather upholstery, heated and ventilated front seats, and a panoramic glass roof added to the luxury, justifying comparisons to the S-Class.
