The Mercedes-Benz GLC-Class is the Stuttgart-based automaker's answer to the likes of the BMW X3, Audi Q5, and even the Jaguar F-Pace. While the GLC offers a variety of engine options, we have decided to focus on two: a petrol and a diesel, both badged as 300 but rather different at the same time. Let’s investigate the two, and see which one we consider the option to go for, when considering a Mercedes-Benz GLC 300 purchase.
A broad overview
The GLC is competing with a host of well-established vehicles within the mid-sized SUV segment. The Mercedes-Benz GLC also received a slight refresh in 2019, which saw the inclusion of redesigned front headlights, a re-styled front bumper, new LED taillights, as well as a refined AMG-line body kit option which adds more aggressive and sporty elements to enhance the car’s appearance. There are other options available for the GLC, which include nice things such as Lane Tracking, Driving Assistance, and an Off-road Package, to name but a few. In 2023 the GLC received a much-awaited refresh and the international reveal of a new Hybrid AMG derivative.
Inside the GLC, you will find a neat and well-designed interior. Recent updates include a new infotainment screen mounted to the top of the dashboard, which now features the brand’s interactive MBUX software. There is also an optional digital instrument cluster, which enables you to change between various themes as well as select which individual items of information you want. The interior is spacious, and the boot will hold around 550 litres.
The GLC 300 petrol
As mentioned earlier, the GLC is offered with a variety of engines, however we have chosen the flagship, non-AMG model as focal point. It’s called the GLC 300, but, despite the 300 badge on the back, it features a 2.0-litre turbocharged four-cylinder engine. It develops 190kW and 370Nm, a slight bump up from the previous model. The Mercedes-Benz GLC 300 will bolt from 0 to 100 km/h in about 6.5 seconds, a time that will give a few hot hatches a run for their money. Power delivery from the 2.0-litre engine is surprisingly smooth and linear, with minimal lag and a wide power band. The engine is mated to a 9-speed automatic gearbox which offers smooth transitions between gears. Mercedes-Benz claims an average fuel consumption figure of around 7.4l/100km.
The GLC 300 diesel
The diesel derivative of the GLC 300 is also worth a look when shopping in this segment, as it also offers impressive performance. Like the petrol version, the 300 badging is all but a badge. Under the bonnet, you will find a 2.0-litre turbodiesel, tuned to develop an impressive 180kW and a monumental 500Nm of torque, colossal figures for a 2.0-litre diesel. The GLC 300d employs the same 9-speed automatic gearbox and AWD system, and will hit 100 km/h in around 6.5 seconds, a near-identical number to that of its petrol counterpart. However, it truly excels in fuel economy, which is claimed to average just 5.6 l/100km.
Verdict
The Mercedes-Benz GLC is an attractive option within the segment, and both variants are worth consideration, The 220 derivatives may deliver less power but just the same as the 300, we feel that the diesel is worth just a little more – if only for its fuel efficiency, and not all that delicious torque.
