2025 Mercedes-Benz GLC vs 2025 Porsche Cayenne

The 2025 Mercedes-Benz GLC adhered closely to the contemporary Mercedes design language, presenting a refreshing sight in the compact crossover segment. Its taut lines contributed to a trim and muscular shape, flowing elegantly from the Mercedes star pattern grille and standard LED headlights. The taller, upright cabin area and short overhangs suggested a sense of multi-terrain capability, particularly in non-AMG Line models with unpainted wheel arch liners. The GLC's crisp headlights and detailed tail lights ensured its look remained fresh, while the optional 20-inch AMG five-spoke wheels enhanced its athletic form. Inside, the GLC exuded luxury with beautifully designed, contrasting-leather-adorned interior door panels and premium materials. The GLC 350e PHEV test unit featured supple white leather seats with heating and ventilation options, offering great adjustability and a commanding road view. The haptic steering wheel and climate controls, though made of piano black plastic, were nicely contrasted by faux carbon fibre, satin-stitched leather, and painted aluminum trim accents.

The 2025 Porsche Cayenne was available as a standard SUV or a sporty Cayenne Coupe, with trim levels ranging from the base Cayenne to the high-performance Cayenne Turbo E-Hybrid. The GTS trim level featured high gloss black trim, a unique front fascia with larger air intakes, tinted headlights, and red brake calipers visible through 21-inch anthracite gray wheels. The Cayenne Coupe offered an adaptive rear spoiler. Inside, the Cayenne allowed extensive customization, from colour choices to trim and seat belts. Pricing could escalate with options like custom paint jobs. The cabin featured numerous screens, with mechanical controls for essential functions like HVAC and volume. The shifter toggle on the dashboard provided more storage space, though the sliding centre console required careful handling. Overall, the Cayenne's cabin was well-thought-out, offering a blend of luxury and functionality.

The 2025 Mercedes-Benz GLC came standard with the Mercedes 4Matic all-wheel drive system in Canada. The entry-level models were powered by a 2.0-litre turbocharged four-cylinder engine paired with a nine-speed automatic transmission. The turbo-four engine produced 255 horsepower and 295 pound-feet of torque in the GLC 300, while the GLC 350e's output was slightly lower at 201 hp and 236 lb-ft. Despite the GLC's curb weight of around 1,900 kilograms, the 300 model featured a 48-volt mild-hybrid system that added 23 hp and 148 lb-ft of torque, enabling a 6.2-second 0-100 km/h time. The 350e's hybrid system included a 23.3-kilowatt-hour battery pack and an electric motor, contributing an extra 134 hp and 235 lb-ft of torque, resulting in a combined output of 313 hp and 406 lb-ft. The 350e had a slower 6.7-second 0-100 km/h time due to its additional weight. The GLC's ride quality, steering, and handling were commendable, with the vehicle absorbing road imperfections well and maintaining composure on highways and winding roads. Braking performance was adequate, and the 350e's regenerative braking system could be adjusted via steering wheel paddles. The GLC's hybridization prioritized electricity over internal combustion, offering an impressive 87-kilometre electric range.

The 2025 Porsche Cayenne offered various engine options, all capable of delivering impressive performance. The base 3.0-litre V6 engine produced 348 horsepower and 368 pound-feet of torque, while the Cayenne S featured a V8 engine with 468 hp. The Turbo GT, available only as a coupe, boasted 650 hp. Plug-in hybrid options offered up to 729 hp for peak performance. The Cayenne GTS trim, with its twin-turbo 4.0-litre V8 engine, delivered 493 hp and 486 lb-ft of torque, paired with an eight-speed transmission and all-wheel drive. The GTS could accelerate to 100 km/h in 4.4 seconds with the Sport Chrono package, reaching a top speed of 275 km/h. The GTS struck a balance between sporty and comfortable performance, with precise steering and agile handling. The vehicle's components, including Pirelli P Zero tires, stiffer roll bars, and an active suspension, contributed to its athleticism. The GTS offered various drive modes, with Sport and Sport Plus enhancing throttle and transmission performance. The optional carbon ceramic brakes provided ample stopping power. In Normal mode, the GTS transformed into a comfortable commuter, retaining its V8 charm. The Cayenne's versatility allowed for a sporty driving experience without sacrificing daily comfort.

The 2025 Mercedes-Benz GLC offered a commanding view of the road, with ample hip, shoulder, and legroom in the front seats, even for a six-foot three-inch driver. However, the back seats were somewhat tight on leg and headroom. The front seats featured a clever design with a curve to maximize rear legroom, though rear-seat passengers couldn't stretch out. The GLC's boxy shape provided 470 litres of cargo space, expanding to 1,530 litres with the rear seats folded down. Despite being lower in cargo capacity than the GLC 300, the GLC 350e remained practical. The split rear seat dropped instantly via buttons behind the hatch, allowing for easy storage of large items like an XL-sized road bike. The GLC's hybridization offered financial benefits, with an estimated fuel economy of 9.6 litres per 100 kilometres over 440 kilometres of driving. The 350e's estimated fuel economy was 10.2 L/100 km city, 8.5 highway, and 9.4 combined in hybrid mode, with an efficiency of 3.7 litres-equivalent per 100 kilometres in all-electric mode. The mild-hybrid 300 returned an estimated 10.0 L/100 km city, 7.6 highway, and 8.9 combined.

The 2025 Porsche Cayenne offered a la carte customization, with the base model featuring standard eight-way power-adjustable seats, heated but with cooling and massage options available at an extra cost. The Cayenne included two-zone climate control, soft-close doors, a heated steering wheel, and ambient lighting. Higher trims offered upgrades like a GT Sport steering wheel and Race-Tex headliner. The options list was extensive, allowing for customization of interior materials, seats, and more. However, the Cayenne lacked a third row of seating, accommodating only five people. The second row provided ample headroom, even in the coupe body style. The Cayenne's towing capacity was impressive, with the base V6 engine capable of towing 3,500 kilograms and accommodating over 635 kilograms of payload. Cargo space was slightly smaller than competitors, with the standard Cayenne offering 772 litres behind the second row, expanding to 1,708 litres with the seats folded down. The coupe version offered 576 and 1,486 litres, respectively. The Cayenne Turbo e-hybrid PHEV had slightly reduced cargo space due to the battery.

The 2025 Mercedes-Benz GLC featured the latest third-generation MBUX infotainment system, with haptic controls for steering wheel, climate, and infotainment functions. The 11.9-inch touchscreen required some adjustment to swipe intensity, as overswiping could lead to rapid screen changes. The touchscreen response was occasionally sluggish, causing confusion when navigating menus. However, wireless Apple CarPlay and Bluetooth connected seamlessly, and Android Auto was standard. The screen resolution was good, and the ambient lighting customization added to the driving experience. The GLC's stereo system, including the Burmester 3D surround sound system, provided excellent audio quality.

The 2025 Porsche Cayenne boasted a range of screens, including a standard 12.6-inch digital gauge cluster with up to seven views, depending on the trim level. The 12.3-inch touchscreen display ran the Porsche Communication Management system, offering wireless Apple CarPlay, Android Auto, Spotify, Apple Music, satellite radio, and a Wi-Fi hotspot. An optional 10.9-inch passenger screen allowed for navigation and media control, with a screen filter preventing driver distraction. The screens were well-organized and responsive, with voice control options available. A head-up display provided pertinent information, though it appeared dim with polarized sunglasses. The system included night-vision assist, and HD-Matrix Design LED headlamps were standard. The Cayenne featured four high-speed USB-C charging ports and a cooled wireless charging area, preventing phone overheating.

The 2025 Mercedes-Benz GLC came standard with advanced safety features, including blind-spot monitoring, active parking assistance, automatic high beams, rain-sensing windshield wipers, and active braking assistance. The optional $2,500 Driver Assistance Package added adaptive cruise control, steering assist with stop-and-go capability, lane-change assist, lane-keep assist, automatic emergency braking, evasive maneuvering, and speed limit assist. These features worked smoothly, with adaptive cruise control and steering assist providing a comfortable driving experience.

The 2025 Porsche Cayenne offered standard safety features like parking sensors, forward collision warning, and blind-spot monitoring. However, adaptive cruise control, lane-keeping assist, and lane-departure warning were optional. Porsche's InnoDrive adaptive cruise control system, which looked ahead approximately 3 kilometres, was not tested due to the car's German specifications. The Cayenne lacked hands-off/eyes-up driving assist features. Neither the NHTSA nor the IIHS had rated the 2025 Cayenne for safety.
