BMW X6 vs Audi SQ8 Comparison 2026: Price, Mileage, Features

Comparison overview: The BMW X6 starts at ₹1.78 Cr and the Audi SQ8 at ₹1.78 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.

Engine and performance: The BMW X6 uses a 4,395cc Petrol making 523bhp@5500rpm and listed torque with Automatic. The Audi SQ8 uses a 3,996cc Petrol making 500bhp@5500rpm and listed torque with Automatic.

Mileage and running cost: The BMW X6 Petrol Automatic is rated at 7.89 kmpl and the Audi SQ8 Petrol Automatic at 7 km/l. At 1,000 km a month, the BMW X6 saves you about ₹1.69 K a month and ₹20.30 K a year on fuel.

What one gives that the other does not: The BMW X6 adds Brake Assist, Child Safety Locks, ISOFIX Child Seat Mounts, Adjustable Headlamps and Rain Sensing Wiper. The Audi SQ8 adds Side Airbag-Rear, Curtain Airbag, Seat Belt Warning, Door Ajar Warning and Speed Alert. The rest of both spec sheets is shared.

Which one should you buy?

Buy the BMW X6 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 Audi SQ8 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 X6 offers Brake Assist.

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.
