BMW 3 Series Long Wheelbase vs Audi A6 Comparison overview

Comparison overview: The BMW 3 Series Long Wheelbase starts at ₹60.50 L and the Audi A6 at ₹63.74 L, a difference of ₹3.24 L ex-showroom. On-road in New Delhi that gap becomes roughly ₹3.60 L. Here is what the extra money actually buys.

Mileage and running cost: These two figures are not like for like. The BMW 3 Series Long Wheelbase number is for the Diesel/Petrol Automatic and the Audi A6 number is for the Petrol Automatic, so compare the variants you are actually shortlisting.

What one gives that the other does not: The BMW 3 Series Long Wheelbase adds Electronic Brakeforce Distribution (EBD), Electronic Stability Control (ESC), Rear Camera, Anti-Pinch Power Windows and Speed Alert. The Audi A6 adds Fog Lights - Front, Rear Spoiler, Chrome Grille, Trunk Opener and Sun Roof. The rest of both spec sheets is shared.

Which one should you buy?

Buy the BMW 3 Series Long Wheelbase if you drive mostly in the city, you want the lower running cost, and you would rather keep the ₹3.24 L for your down payment than spend it on features.

Buy the Audi A6 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 3 Series Long Wheelbase offers Electronic Brakeforce Distribution (EBD).

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.
