2025 Mercedes-AMG GLC-Class vs BMW X3 M: Which is Better?
Mercedes-AMG’s high-performance lineup, embracing electrification with models like the GLC43 and plug-in hybrid GLC63 S E Performance, showcases a shift toward hybrid technology rather than full electric power. The GLC43 boasts 416 horsepower from its turbo-four and 48-volt hybrid setup, while the plug-in GLC63 S E Performance cranks it up to 671 horses with an electric motor and onboard battery. On the other hand, the BMW X3 M, derived from the more subdued X3, conceals a beast beneath its exterior. Powered by a twin-turbo six-cylinder, the X3 M, especially in its 503-horsepower Competition trim, delivers a thrilling driving experience with a wild exhaust note and even a rear-drive drift mode. Despite a firm ride, it maintains the luxurious features of the standard X3, appealing to those seeking a balance between performance and comfort.

Mercedes-AMG GLC-Class
Engine & Performance
Rev up your driving experience with the GLC43, boasting a robust 416 horsepower from its turbocharged 2.0-liter four-cylinder—quite the leap from the GLC300’s modest 255 ponies. Powering this beast is a 48-volt hybrid system, seamlessly integrated with all-wheel drive and a nine-speed automatic transmission for an exhilarating ride. Stepping into the electrified realm, the top-tier GLC63 S E Performance cranks up the intensity. Mercedes-AMG injects extra power, reaching a staggering 671 horsepower and 752 lb-ft of torque, thanks to an added electric motor. Like its counterpart, the 63 model delivers power to all wheels through a nine-speed automatic, ensuring a dynamic and electrifying drive. Upgrade your journey with the GLC43 or go all-in with the electrified prowess of the GLC63 S E Performance—both promising an exhilarating and seamless driving experience.
Price & Mileage
Although we’re yet to experience the thrill firsthand, our bet leans heavily towards the GLC63 S E Performance model as the top choice. Its substantial power advantage over the GLC43 promises an impressive performance on the drag strip. Notably, it stands out as the sole option offering an all-electric driving range. Anticipated to kick off at an estimated $70,000, the GLC-Class holds intrigue. While the EPA hasn’t disclosed the AMG GLC’s fuel efficiency, we predict it might slightly dip below the GLC300’s figures, resting at 23 mpg city and 31 mpg highway. With its potent features, the GLC63 S E Performance appears poised to redefine expectations in the luxury SUV realm.
Acceleration & Features
Zooming from 0 to 60 mph in a mere 5.6 seconds during testing, the GLC300 promises an even snappier performance with an extra 162 horsepower. The GLC63 takes it up a notch, boasting a jaw-dropping 3.4-second sprint to 60 mph. Every model flaunts a 12.3-inch digital gauge display alongside an expansive 11.9-inch infotainment touchscreen. This tech marvel responds to voice commands and supports standard wireless Apple CarPlay and Android Auto. Optional delights encompass a head-up display and a top-tier Burmester stereo system. Notably absent are physical HVAC buttons and an audio volume knob, as the control shifts to the touch screen—an adjustment that, in our perspective, leans away from the user-friendly design.
BMW X3 M
Engine & Performance
In the realm of crossovers, the twin-turbo 3.0-liter inline-six-cylinder in this BMW not only exudes power but also boasts a seamless performance. Meticulously fine-tuned by the M performance division, this mill cranks out a dynamic range, spanning from 473 to a formidable 503 horsepower, and a torque prowess ranging between 457 and 479 pound-feet. The apex of this power resides in the Competition model, featuring not only the extra power but also a standard sport exhaust system and imposing 21-inch wheels. Each X3 M is equipped with an eight-speed automatic transmission, seamlessly synchronized with an all-wheel-drive system capable of channeling 100 percent of the engine’s torque to the rear wheels as circumstances demand. This not only ensures a spirited drive but also exemplifies the dynamic versatility of this crossover.
Price & Mileage
Yearning for added power and upgraded features? Look no further than the BMW X3 M, a powerhouse that begins at a price point of $76,495. Whether opting for the Competition package or not, both versions are projected to achieve a fuel efficiency of 15 mpg in urban settings and an impressive 20 mpg on the open highway. This means you can revel in enhanced performance without compromising fuel economy. The Competition model, in particular, beckons with its enticing blend of extra power and top-tier equipment. So, if you’re eager to elevate your driving experience, the BMW X3 M, with its dynamic options, awaits your exploration.
Acceleration & Features
In the daring trial of the X3 M Competition, its staggering speed and unexpected agility redefine expectations. Zooming to 60 mph in a mere 3.2 seconds, it swiftly bridges the gap from 50 to 70 mph in just 3.1 ticks, accomplishing the quarter-mile in a rapid 11.5 seconds at 119 mph. Impressively, the X3 M halts from 70 mph in a mere 146 feet and conquers the skidpad with a remarkable 0.97 g of grip. The tech-savvy cockpit boasts a 12.3-inch touchscreen infotainment system, offering diverse control options.
