Audi A6 vs BMW 5 Series LWB vs Mercedes-Benz E-Class (2026)
The classic luxury sedan shortlist, settled with numbers (October 2026):
- Pick the Audi A6 if you want the lowest starting price (₹64.81 Lakh).
- Pick the BMW 5 Series LWB as the balanced middle path — it wins no single spec outright but concedes little anywhere.
- Pick the Mercedes-Benz E-Class if you want the most power (577 bhp), the biggest boot (540 L).
Three-Way Specification Comparison
Audi A6 in short
The A6 is Audi's executive sedan in India, running ₹64.81 lakh (MY2025 base) to ₹71.66 lakh (Technology) with a 245 PS 2.0L TFSI mild-hybrid petrol. This C8 generation is in runout — the all-new A6 is expected in India around October — which makes the current car the value play of the class: it undercuts the BMW 5 Series LWB by nearly ₹12 lakh and the Mercedes E-Class by more. Unlike those two, the A6 runs a standard wheelbase.

Its 258 PS 2.0L turbo-petrol carries 48V mild-hybrid assistance, and the stretched body targets the Mercedes-Benz E-Class LWB — the only other long-wheelbase sedan in the class — head on. Buyers wanting an electric 5 Series get the closely related i5 eDrive35L at ₹79.60 lakh.

The E-Class LWB is India's best-selling luxury car, and the current generation launched in October 2024 continues the formula that earned that title: an India-specific long-wheelbase body with a 3,094 mm wheelbase, reclining rear seats and a 540-litre boot. The range spans ₹81.50 lakh (E 200) to ₹1.45 crore for the 585 PS AMG E 53 Hybrid 4MATIC+ plug-in hybrid. India is one of the few markets to get the LWB sedan at all — the BMW 5 Series LWB is its only direct long-wheelbase rival, with the Audi A6 running standard length.
