Mercedes-Benz AMG A 45 S vs Mercedes-Benz AMG GLC 43 Comparison 2026: Price, Mileage, Features

Comparison overview: The Mercedes-Benz AMG A 45 S starts at ₹87.00 L and the Mercedes-Benz AMG GLC 43 at ₹99.35 L, a difference of ₹12.35 L ex-showroom. On-road in New Delhi that gap becomes roughly ₹13.71 L. Here is what the extra money actually buys.

Engine and performance: Both cars use the same 1991cc Petrol engine and Automatic gearbox, so performance will not decide this for you. Price, features and boot space will.

Mileage and running cost: These two figures are not like for like. The Mercedes-Benz AMG A 45 S number is for the Petrol Automatic and the Mercedes-Benz AMG GLC 43 number is for the Petrol Automatic, so compare the variants you are actually shortlisting.

What one gives that the other does not: The Mercedes-Benz AMG A 45 S adds ISOFIX Child Seat Mounts, Heads-Up Display (HUD), Global NCAP Safety Rating, Rear Spoiler and Chrome Grille. The Mercedes-Benz AMG GLC 43 adds Child Safety Locks, Curtain Airbag, Electronic Brakeforce Distribution (EBD), Rear Camera and Anti-Pinch Power Windows. The rest of both spec sheets is shared.

Which one should you buy?

Buy the Mercedes-Benz AMG A 45 S if you drive mostly in the city, you want the lower running cost, and you would rather keep the ₹12.35 L for your down payment than spend it on features.

Buy the Mercedes-Benz AMG GLC 43 if you do regular highway runs, you carry luggage or a pram often, and you want Anti-lock Braking System (ABS) without waiting for the next facelift.

The one thing that settles it: Mercedes-Benz AMG A 45 S offers ISOFIX Child Seat Mounts.

Before you sign anything:

Ex-showroom price is not what you pay. Add registration, road tax, insurance and handling, and expect the final figure to land ten to twelve percent higher. Road tax changes state to state, so a car that costs the same in two cities does not cost the same to own.

Ask the dealer four things before you book. What is the current waiting period for the variant you want. What is the on-road figure.

Then drive both cars back to back on the same day, on a road you actually use. Take your family. Put your usual luggage in the boot. Most people decide in the first ten minutes, and it is rarely for the reason they expected.
