Our opinion

The Mercedes-Benz GLC 300 e 4MATIC is the plug-in hybrid version of the latest GLC, combining a 2.0-litre petrol engine with a large battery (big for a PHEV) and electric motor. On paper, it offers huge efficiency numbers—but like all PHEVs, that depends entirely on how often you plug it in. Used properly, it works brilliantly. Short daily commutes can be done fully electric, and the petrol engine quietly takes over for long motorway trips. It’s not a hardcore driver’s SUV, but as a premium family all-rounder, it’s very well judged. Range Accuracy & Ease of Charge Official electric range is over 70 miles (WLTP), which is excellent for a plug-in hybrid. In real UK conditions, expect around 60–80 miles in mixed driving if temperatures are mild and you’re not driving aggressively. In winter or at motorway speeds, that drops. Charging is one of its strengths. It supports up to 11 kW AC charging, meaning a full charge can take around 2–3 hours when conditions are right. DC charging is available on some versions (rare in PHEVs), but realistically most owners will charge at home or at work. If you don’t plug it in regularly, fuel economy becomes average rather than impressive. Space & Practicality It’s a proper mid-size SUV. Rear legroom is generous, and it easily handles family duties. The battery eats slightly into boot capacity compared with mild-hybrid or diesel versions, but it’s still practical enough for pushchairs and holiday luggage. Cabin storage is decent, and the driving position is comfortable with good visibility. It feels like a grown-up family car rather than a lifestyle SUV. Driving & Handling Around town in EV mode, it’s smooth and almost silent. The electric torque makes it feel quicker than you expect for a heavy SUV. When you combine petrol and electric power, it’s genuinely fast for its size. That said, you feel the weight in tighter corners. It’s more about stability and comfort than agility. On motorways, it’s excellent—quiet, planted, and relaxed. Ease of Use (Controls & Infotainment) The latest MBUX system dominates the dashboard via a large central touchscreen. Climate controls are integrated into the screen (not separate physical knobs), though they’re permanently visible on the lower section. There’s also a digital driver display—no traditional analogue dials. The system is modern and responsive, but it can take a few days to get used to. If you prefer physical buttons for everything, this setup may frustrate you. Voice control works well for basic functions. Bottom line If you can charge at home or at work, the GLC 300 e 4MATIC makes a lot of sense. It gives you proper electric daily driving with none of the range anxiety of a full EV, plus long-distance comfort. It’s not cheap, and it’s not sporty in the way some rivals try to be. But as a premium, efficient, do-everything family SUV, it’s one of the more complete plug-in hybrids on sale in the UK. Competitors & Alternatives Main rivals include the BMW X3 xDrive30e (slightly sharper to drive), Audi Q5 TFSI e (solid and discreet), Volvo XC60 Recharge (strong electric range, very comfortable), Lexus NX 450h+ (very efficient, less sporty), Range Rover Evoque P300e (more style-led, smaller inside), and the Porsche Macan (more driver-focused but pricier and less EV range in PHEV form depending on market). If you want more space, a BMW X5 xDrive50e or Volvo XC90 Recharge could also be worth a look, but they’re a step up in size and price.
