The BMW 3 Series has long been the benchmark for the executive sports sedan worldwide. However, for a market like India, where the chauffeur-driven experience dictates luxury segment purchasing, BMW introduced a strategic masterpiece: the 3 Series Long Wheelbase (LWB), previously known as the Gran Limousine.
Launched specifically to cater to the high demand for rear-seat comfort, the 3 Series LWB retains the dynamic driving character of the standard 3 Series while offering a crucial extra 110 mm of wheelbase. This extension translates directly into segment-leading legroom, effectively positioning it as a compelling, more affordable alternative to the 5 Series, and a direct rival to the Mercedes-Benz C-Class and Audi A4.

Its competitive ₹60.60 lakh to ₹65.00 lakh ex-showroom price, coupled with the latest interior technology (Curved Display, OS 8.5), unmatched rear legroom, and powerful yet efficient 2.0 L turbo engines, makes it the default choice for the discerning buyer in the ₹70 lakh to ₹80 lakh on−road luxury segment. It delivers 90% of the executive experience of its larger siblings at 70% of the cost.
For the Indian consumer, the 3 Series LWB represents an investment in a German engineered masterpiece that respects both the driver (with its dynamic performance) and the driven (with its luxurious, spacious rear cabin).
