Mercedes-Benz GLC (2020) - The German giant's best-selling SUV

The Mercedes GLC is a mid-sized family SUV with plenty of space, style and luxury to make it an enticing prospect for future buyers. In 2019, one in three of all Mercedes-Benz cars sold worldwide was an SUV variant, and the GLC was the best-selling SUV in the German Manufacturer's range.

Mercedes were a little late getting the GLC to the SUV party in the UK, as there were already several rival models available such as the BMW X3, Audi Q5 and Range Rover Evoque. Mercedes did have the GLK available throughout Europe but decided not to bring to the UK, therefore, missing out on valuable sales. When Mercedes finally released their mid-sized family SUV to the UK market in 2016, it has gone from strength to strength and proven to be one of the best-selling SUVs in its class.


Following suit with rival manufacturers, Mercedes-Benz designed and released a Coupe version of the GLC, to add that little extra sportiness to the traditional SUV silhouette. The compact SUV market is filled with an abundance of fantastic offerings, each with its own unique styling and performance packages. Not only do we have the standard SUV's, but we now have Coupe versions thrown in the mix, as well with the GLC Coupe likely to be up against stiff competition such as the BMW X4.

The GLC was given a mid-life facelift in 2019 as Mercedes sought to keep their compact SUV up to date and on top of the market to help it fend off the stiff competition. When it comes to trim levels, Mercedes, have gone a little OTT. There are 11 different model variations, ranging from the entry-level GLC Sport right the way up to the top-specced Mercedes-AMG GLC 63 and 63S. Mercedes has also added a new hybrid model badged the GLC 300 e to its line-up, so there should now be a Mercedes-Benz GLC to suit anyone's needs and requirements.

Engines, Power and Performance

There are two diesel engines both sharing the same 2-litre four-cylinder unit but with different power outputs, an all-new petrol/electric hybrid motor and a choice of four different petrol offerings.

The types of diesel engines are badged the 220d and 300d with the 300d offering the most power. The 220d develops 194hp and will get from 0-62mph in 7.9secs and climb to a top speed of 134mph.

The 300d gets a further power increase to 245hp, which brings the 0-62mph time down to just 6.5secs and changes the top speed to 144mph. Both diesel engines perform admirably and pull the GLC along with ease and offer more than enough performance to give you confidence when overtaking.

The petrol line-up kicks off with the GLC 300 which uses a 2-litre four-cylinder turbocharged engine combined with Mercedes' EQ Boost mild hybrid system which recoups energy under braking and can then re-use when accelerating. The engine develops 258hp and is capable of racing from 0-62mph in 6.2secs and will keep going to a top speed of 149mph.

Next up is a 3-litre V6 petrol engine found in the GLC 43, which develops an impressive 390hp  and will rocket from 0-62mph in a blistering 4.9secs and go on to a top speed of 155mph.


The final petrol unit is a 4-litre V8 which is shared by the GLC 63 and GLC 63S but the 63S eeks out a little extra power. The GLC 63 unit develops 476hp and will hit 0-62mph in just 4secs and will climb to a top speed of 155mph.

The GLC 63S gains and extra 34hp giving it a whopping 510hp and a lightening time of just 3.8secs to hit 0-62mph. It has a limited top speed of 155mph, but if you add the Driver's Package, its top speed will raise to 174mph.

Finally, there's the all-new hybrid model, the GLC 300 e. It features a 2-litre four-cylinder petrol engine combined with a 90Kw, 122hp electric motor to give a combined power output of 333hp. It will hit 0-62mph in just 5.7secs and is capable of an impressive top speed of 143mph.

Each GLC engine is paired Mercedes' 9G-Tronic automatic transmission to help reduce fuel consumption and noise level. Every GLC also benefits from the Mercedes 4MATIC (AWD) drive system for added traction and stability, a necessity when you consider the power that some of these fantastic engines generate.

Interior Quality and Technology

The interior and dashboard are a pretty much a copy of that found in the new Mercedes C Class which is not a bad thing. As we have come to expect from Mercedes, the standard of materials used, and the build quality are exceptionally high end and are of premium levels.


Every GLC receives a host of the latest Mercedes technology and features as standard, such as a bright, crystal clear 10.25inch colour touchscreen to support the latest MBUX infotainment system. Some of the other standard features on the impressive list are sat-nav, DAB Radio, parking sensors with reversing camera and a voice assistant which is activated when you say "Hey Mercedes".

Finding a great driving position should also be easy, as all come with at least some electrically adjustment in the front seats along with four-way adjustable lumbar support for added comfort on those longer journeys. The steering wheel also has a good amount of adjustment, and the standard seat height is good, not too high but not too low, Mercedes have got it pretty much bang on.


If you choose AMG Line Premium trim level, then the analogue driver display dials are replaced by a fully digital and customisable 12.3inch colour display instrument cluster. You also get 20-inch alloy wheels, AMG leather sports seats and smartphone connectivity with Apple CarPlay and Android Auto to list just a few of the additional features.

Space, Practicality and Safety

The GLC is fairly spacious inside and will comfortably fit four larger than average-sized adults in without a problem and five at a squeeze, but is ideal for shorter trips. In the front, there is more than enough legroom to satisfy even the longest of legged occupant's, thanks in part to front seats which slide back more than you would expect. Headroom again is impressive, and those in the front should have no issues even if you have opted to have the panoramic sunroof (standard on Premium Plus trim level and above).


In the back, generous amounts of legroom await your passengers, and headroom again is good; however, with the panoramic sunroof, taller adults will find the tips of their hair brushing against it. The middle seat is more suitable for a small child due to limited foot and leg room allowed, thanks to the large transmission tunnel running up the centre of the car.

The boot is a generous size coming in with a capacity of 550-litres rising to 1600-litres with the rear seats folded away making it more substantial than the Range Rover Evoque and Porsche Macan rivals and coincidentally is the exact same size as the boot in the BMW X3.


The Mercedes GLC was awarded a Top 5 Star rating at the Euro NCAP safety tests thanks to a selection of advanced safety features with particularly high scoring in the adult and child occupant safety.

Some of the standard safety features included across the GLC range are; PARKTRONIC Active Parking Assist with reversing camera, multiple airbags and Collision Prevention Assist. There are various additional safety packages on offer such as the Driving Assistance Pack, some of which come as standard on higher trim models.

Overall the Mercedes GLC is a fantastic compact family SUV offering style, luxury and comfort, perfect for those family holidays to the seaside or road trip to the South of France. If you want a more sporty looking SUV, then the GLC Coupe should be right up your street.
