NEW DELHI: Mercedes-Benz lists a 620-litre boot for both the GLC 300 4MATIC petrol and GLC 220d 4MATIC diesel on its India model page. The shared luggage figure means the engine choice does not change the published boot capacity. The practical differences begin with the powertrain, while parking space and bag shape need separate checks.

The separate official India price listing puts the petrol and diesel GLC family from Rs 77,00,000. Price as of 6 November 2026, 00:20 IST. It does not disclose an individual price for each engine in the accessible listing, so this is a specification explainer rather than a complete variant price list.
What 620 litres can and cannot answer
A boot-capacity figure gives a useful reference when comparing vehicles, but a household carries objects rather than litres. A folded pushchair, a golf bag and a hard suitcase all use space differently. The question for this GLC is whether the opening and floor arrangement accept the items that usually travel together.
For an airport run, bring the luggage you actually use to a demonstration. Place it below the normal cover position and check whether the tailgate closes without rearranging the cabin. For a family holiday, repeat the exercise with the smaller bags that tend to accompany larger cases. This is a better test than assigning an arbitrary suitcase count to the official volume.
The same boot leaves room for a different engine decision
The petrol and diesel entries provide distinct performance descriptions without changing the stated luggage capacity. That allows the household to settle cargo suitability first and assess the engine on its own terms. There is no need to infer a boot-space sacrifice from the fuel label when the official figures are the same.
The torque and acceleration entries also show why an isolated engine number can mislead. More listed torque does not, by itself, establish quicker acceleration. The complete powertrain and vehicle matter. Here the manufacturer's published acceleration claims give a direct comparison, although they remain official claims rather than times measured during this report.
Measure the parking bay with mirrors in mind
The mirror-inclusive width is especially relevant to a narrow basement lane or home gate. A body-width measurement alone would leave part of the vehicle out of that calculation. Measure the approach as well as the space where the car eventually stands, including obstructions at mirror height.
Then consider how the tailgate will be used after parking. A bay can accommodate the car while leaving awkward access to luggage against a wall. Try the loading routine from the position in which the GLC would normally be parked. A generous boot has less practical value if the family cannot comfortably reach it in the place where most loading happens.
Keep the family arrangement in the test
The seating entry identifies the GLC as a family SUV without a third seating row in these technical listings. For a household that regularly travels together, assess the rear bench with the usual occupants in place. If a child restraint is part of the routine, check its fit and the remaining access before evaluating decorative cabin details.
Ask passengers to put their everyday items where they would during a journey. Check whether coats, school bags and charging cables create clutter around the seating area. Those observations help distinguish usable family accommodation from an impressive boot number, particularly when the GLC is expected to manage school duties and longer journeys alike.
Be careful to open the petrol and diesel GLC listing when checking these figures. The price overview also carries a separate electric GLC entry, which this luggage comparison does not cover.
Who it is for
This GLC specification suits readers considering a premium family SUV who want to understand luggage space before settling the powertrain. The petrol's published acceleration and the diesel's torque figure offer different starting points for that discussion. Neither substitutes for a drive on a route resembling the owner's normal use.
