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.
