Comparison: Mercedes-Benz C-Class vs BMW 3 Series Gran Limousine (2025 Edition)

A timeless duel between two sedans that have long anchored their brands solidly within India’s luxury market. These cars, for many decades, were the epitome of new-age luxury for German automobile-buying audiences. The Mercedes C-Class India was synonymous with luxury comfort and also symbolized luxury. The BMW 3 Series Gran Limousine earned its stripes by being known as the enthusiast’s preferred choice.

However, for this particular luxury sedan comparison test, both have undergone significant evolution. The 3 Series gained a new long-wheelbase Gran Limousine variant, aimed at prioritizing comfort for rear-seat occupants. The C-Class borrowed styling inspiration from its sibling, the AMG, and was equipped with new power units featuring mild-hybrid technology. Both cars also graduated from the “entry-luxury” tier and took on a pricier role above their earlier selves.

How do these evolved sedans stack up in 2025? Let’s find out.

Mercedes-Benz C-Class vs BMW 3 Series Gran Limousine: Dimensions

There’s a common belief among Indian buyers—if you’re spending more, you expect a bigger car. In this regard, the BMW 3 Series Gran Limousine has a clear advantage.

The nearly 100 mm longer wheelbase of the BMW translates to slightly more rear legroom and a strong selling point for those interested in chauffeur-driven motoring. The boot is also larger, although both cars’ spare tyres intrude on usable capacity.

Visually, the C-Class also features AMG styling touches, such as a widened base grille, a tauter silhouette, and aggressive bonnet creases. This gives a sportier, more aggressive presence. In contrast, the BMW 3 Series Gran Limousine brings together its sporty proportions and longer, more stately profile enhanced by a macro-teasing stance and chic detailing.

Both the Mercedes C-Class India and the BMW 3 Series Gran Limousine bring plenty of firepower under the bonnet. For 2025, Mercedes continues to use its 48V mild-hybrid setup across the range, while BMW sticks to its proven 2.0-litre petrol and diesel engines, now updated to meet BS6 Phase 2 norms.

• The C-Class mild-hybrid system adds a smooth electric boost under hard throttle and helps improve real-world fuel economy.

If driving excitement is your priority, the BMW 3 Series Gran Limousine remains the driver’s choice. But for effortless torque and mild-hybrid refinement, the C-Class diesels are hard to beat.
