BMW 7 Series vs BMW M4 CS Comparison 2026: Price, Mileage, Features

Comparison overview: The BMW 7 Series starts at ₹1.79 Cr and the BMW M4 CS at ₹1.79 Cr, a difference of the listed price gap ex-showroom. On-road in New Delhi that gap becomes roughly the city on-road price gap. Here is what the extra money actually buys.

Mileage and running cost: These two figures are not like for like. The BMW 7 Series number is for the Diesel/Petrol Automatic and the BMW M4 CS number is for the Petrol Automatic, so compare the variants you are actually shortlisting.

What one gives that the other does not: The BMW 7 Series adds Power Door Locks, Passenger Side Rear View Mirror, Rear Seat Belts, Side Impact Beams and Front Impact Beams. The BMW M4 CS adds Electronic Brakeforce Distribution (EBD), Anti-Theft Device, Anti-Pinch Power Windows, Hill Descent Control and Hill Assist. The rest of both spec sheets is shared.

Which one should you buy?

Buy the BMW 7 Series if you drive mostly in the city, you want the lower running cost, and you would rather keep the the listed price gap for your down payment than spend it on features.

Buy the BMW M4 CS 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: BMW 7 Series offers Power Door Locks.

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.
