BMW i5 LWB and Mercedes E-Class: Electric and Diesel Showdown for Luxury Sedans

BMW no longer offers a diesel engine with the 5 Series in India, so for buyers with high annual running who want an efficient 5 Series, the electric i5 is the only option. The E-Class, meanwhile, continues to offer a diesel powertrain in the form of the E 220d, alongside petrol versions. Both are aimed at buyers seeking a spacious, chauffeur-friendly luxury sedan, but their powertrains make for very different ownership propositions. The i5 LWB is significantly wider, with a 276mm advantage over the E-Class, while the two are fairly similar in length, height and wheelbase. The BMW also gets larger 20-inch wheels compared with the Mercedes's 18-inch units. The i5 LWB gets rear-axle air suspension, which should help with ride comfort, while the E 220d uses a steel setup with selective damping. The i5 has the clear advantage in power and acceleration, but the E 220d has more torque than its electric rival. The i5 should also be smoother, as expected of an EV, while the E-Class is exceptionally fuel efficient for a luxury sedan and can manage more than 800km on a full tank. The i5 gets a large 81.6kWh battery pack and has a claimed range of 669km, which should be achievable in highway runs. The E 220d, however, is better suited to those who regularly mix city driving with long highway journeys and want the convenience of quick refuelling. Both sedans are similarly equipped in terms of exterior features, with the i5 LWB getting adaptive LED headlights and an illuminated grille. In contrast, the E-Class gets flush-fitting door handles. Both offer a similar baseline of luxury equipment, but their priorities differ. The i5 adds ventilated front seats and a larger central display, while the E 220d has a more comprehensive set of rear-seat features, including electric recline, sunblinds, soft-close doors and the ability to adjust the front passenger seat from the rear. For a chauffeur-driven buyer, that gives the Mercedes an advantage in rear-seat functionality. The two cars are closely matched on safety features, with both offering 8 airbags, lane departure warning, blind-spot monitoring, automatic emergency braking, 360-degree cameras and parking assistance. At Rs 79.60 lakh, the i5 LWB is Rs 3.90 lakh more affordable than the E 220d and is also cheaper than the petrol E-Class. Factoring in the lower running costs of an EV, particularly for buyers who can charge at home, the BMW makes a strong financial case. On paper, the BMW i5 LWB is the stronger choice if outright performance, lower running costs and a more front-seat-focused cabin are priorities. It is more powerful, quicker and cheaper to buy, while home charging can make it substantially cheaper to run.
