2021 Audi Q5 Reviews SummaryAudi has made a commitment to electrification across its lineup. That takes the form of all-electric (BEV), hybrid (HEV), and plug-in hybrid vehicles (PHEV). The Q5, which entered its second generation in the 2018 model year, has offered a PHEV powertrain since 2020 in the Audi Q5 TFSI e quattro. | |
2021 Mercedes-Benz GLC Reviews SummaryThe modern compact luxury SUV market is an embarrassment of riches. Shoppers have more options than ever before, and all of them are terrific vehicles. There’s the BMW X3, Audi Q5, Volvo XC60, Acura RDX, Alfa Romeo Stelvio, and even the newcomer Lincoln Corsair. Not to be left out of this dizzying list is one of the segment’s most popular options, the 2021 Mercedes-Benz GLC. While the X3 arguably kicked off the small luxury SUV craze, the bar was raised with the GLC’s predecessor, the GLK. But even the GLK felt like a stopgap compared to a fully realized vehicle like the GLC. It encapsulates everything that buyers are looking for in a compact luxury SUV—an upscale cabin, cutting-edge infotainment and safety technology, and driving dynamics that are equal parts athletic and comfortable. Many vehicles in the aforementioned list have some or all of these things, but few combine them all as elegantly as the GLC. Mercedes-Benz happily boasts the GLC is its best-seller, and with good reason. But should you count yourself among one of their customers? Read on to find out. | |

The 2021 Audi Q5 was a sharp-looking crossover SUV that embodied the Audi design language while maintaining its unique character. It featured an expressive front with LED headlights and a prominent Singleframe grille, emphasizing width with horizontal elements. The body showcased crisp character lines, and the rear was marked by bold, large taillights. The Q5's overall appearance was classy and modern, with exceptional fit and finish. The plug-in hybrid version included S-Line trim pieces and enhancements, offering a more refined look with standard 19-inch wheels or optional 20-inch wheels.
Inside, the Q5 maintained a classy and modern aesthetic, packed with technology yet uncluttered. Controls were smartly grouped by function, and the design was cohesive and pleasing. High-quality materials were used throughout, with real wood and metal accents. The 10.1-inch touchscreen was positioned for optimal driver visibility. The second row was well-appointed, featuring standard leather upholstery, ensuring comfort for all passengers.
The 2021 Mercedes-Benz GLC embraced a timeless aesthetic with soft curves and rounded edges, contrasting with the aggressive styling trends of the time.

The GLC's exterior was attractive, and its cabin was an automotive work of art, with flowing lines and a minimalist approach. The interior design set a high standard for compact luxury SUV cabins.
The GLC was available in both conventional SUV and crossover "coupe" body styles. The coupe's sharp look came at the cost of usable space. Standard equipment on the GLC 300 included 19-inch alloy wheels, LED headlights, and a power liftgate. Inside, it featured synthetic leather upholstery, power-adjustable and heated front seats, dual-zone climate control, and the MBUX infotainment system.

Apple CarPlay and Android Auto were integrated, although switching between the GLC's radio and smartphone apps required navigating through menus.
The 2021 Audi Q5 PHEV had not been rated by the IIHS, but the 2020 gasoline model received top "good" ratings in most categories. The NHTSA awarded the 2021 gasoline model five stars. Safety features included six airbags, ABS with brake assist, electronic stability control, and various driver-assistance systems like Audi Pre Sense front and adaptive cruise control.
