BMW 3 Series LWB Vs Audi A6 Vs BMW 3 Series Vs Mercedes-Benz E-Class FAQs

The 2025 facelift BMW 3 Series Long Wheelbase (LWB) starts from ₹63.90 lakh ex-showroom, for the petrol 330Li M Sport variant. Diesel variants (320Ld M Sport / M Sport Pro) are priced slightly lower or around that range, with some petrols slightly higher depending on state taxes.

Petrol 330Li M Sport uses a 2.0-litre twin-turbo petrol motor producing ~ 258 bhp (≈ 254-258 PS) and 400 Nm torque. Diesel 320Ld variants produce ~ 190 PS with similar torque (~400 Nm).

Diesel variant is claimed to be better in term of mileage; some reports suggest ~ 19.6 kmpl for the diesel engine in mixed driving. Petrol will be lower; real-world mixed driving probably ~ 12-15 kmpl or less, depending on traffic.

1. Routine service (oil, filters, inspections): likely ₹ 40,000-80,000+ depending on variant and usage. Diesel tends to cost a bit more due to diesel-specific components. Major servicing, tyres, brakes etc will add extra. Premium tyres and performance brakes cost more. 2. Insurance for this sedan will be fairly high because of its luxury status: potentially ₹ 1-1.5 lakh/year or more depending on city, driver profile, and cover. 3. Extended service/warranty packages exist (BMW’s Service Inclusive etc) which help reduce surprises; check these when buying.

1. Standard safety: 6 airbags, ABS, Dynamic Stability Control (DSC), Cornering Brake Control (CBC), ISOFIX mounts for child seats. 2. Also equipped with blind-spot detection, collision warning, attention assistance, driving assistant package (Level-2 ADAS elements) like rear-cross traffic warning.

1. Length ~ 4,819 mm, wheelbase ~ 2,961 mm. That gives spacious rear legroom. 2. Boot space is good (similar to shorter 3 Series), but more relevant is rear-seat comfort. If someone is going to use it as chauffeur-driven or carry rear passengers often, this shines. For solo driving in tight parking spaces, you’ll have to adapt.

Yes, with caveats: Petrol version’s fuel cost will be high in stop & go traffic, diesel helps here. Parking big sedan requires space; reversing camera, sensors and surround view help. Speed breakers and potholes need care because of long wheelbase / low under-body clearance. Service centres, parts cost more than non-luxury sedans.

Luxury sedans do depreciate notably, especially as new models and variants arrive. Diesel vs petrol trend: diesel engines may face heavier regulation / higher running cost (fuel/diesel price), which can affect resale. Petrol might retain value better depending on usage.

As of Sep-2025, after GST 2.0 changes, the ex-showroom price of the Audi A6 starts around ₹63.74 lakh. This puts it right in the sweet spot of the luxury executive sedan segment.

The claimed fuel efficiency is about 14.11 kmpl.

The Audi A6 comes with a 1984 cc petrol engine.

Length: 4939 mm, Width: 2110 mm, Height: 1470 mm. It has serious road presence, though tight parking spaces may feel challenging.

The boot space of Audi A6 is 530 litres. Perfect for weekend getaways or airport luggage runs.

The ground clearance is approximately 165 mm. Sufficient for city roads, but you’ll need care over large speed breakers.

The estimated maintenance cost of Audi A6 for 5 years is around ₹3 to 3.5 lakh. Standard upkeep for a luxury German sedan.

With a mileage of 14.11 kmpl and petrol price of ₹100/litre, the running cost is about ₹7 per km. Luxury travel at a cost that stays reasonable for the segment.

Currently, the Audi A6 in India is offered with a petrol engine only. Smooth and refined, though diesel fans may miss the torque surge.

Main rivals include BMW 5 Series, Mercedes-Benz E-Class, Jaguar XF, and Volvo S90.

Yes, all Audi A6 variants in India come with automatic transmission. The gearbox is smooth, making both city drives and highway runs effortless.

The current BMW 3 Series in its premium spec (M340i xDrive) is priced at ₹ around 75 lakh ex-showroom. Depending on your city, add registration, insurance, state tax etc., which can push the on-road price (Delhi or similar) to around ₹ 80 lakh or more.

The 3 Series’ top petrol version (M340i xDrive) uses a 2,998 cc inline-6 turbocharged petrol engine. It delivers around 368-370 horsepower and 500 Nm torque, with 0-100 km/h sprint time in roughly 4.4 seconds.

The M340i xDrive version gives about 13.02 kmpl (ARAI) in combined driving.

If you drive 10,000 km/year, fuel cost (M340i) will be ~ ₹ 82,300.

Routine service (oil change, filters, inspections) for a BMW sedan like 3 Series can cost ₹ 50,000-₹ 1,00,000+ per service depending on variant & parts needed (especially for imported or premium components). Wear items like brakes, tyres (premium), suspension components cost more than average sedans. Insurance: Because the on-road value is high (Rs 70-80 lakh), insurance premium will be high: likely ₹ 1-2 lakh/year or more, depending on coverage, driver record etc. Other costs: spare parts from BMW, malfunctions in electronics, servicing from authorised centres only—adds cost and waiting times.

Safety features include 6 airbags, LED headlamps, ABS + EBD, Electronic Stability Programme (ESP), Traction Control, Hill Start Assist etc.

Yes, but with caveats. If your routine includes highways or open roads, you’ll enjoy performance, stability, and comfort. In city traffic, low speeds, stop-go etc will reduce mileage, increase wear & tear. Also servicing + fuel + insurance cost adds up markedly. If you accept that and budget properly, 3 Series can be a very satisfying daily sedan. If your budget is tight or roads bad, might feel expensive to maintain.

Luxury / premium sedans (especially import or higher spec) depreciate steeply in the first few years in India. BMW brand helps, but maintenance history matters more.

The ex-showroom price of the Mercedes-Benz E-Class in India ranges from ₹78.50 lakh to ₹91.65 lakh. The on-road price can start from around ₹90 lakh and go up to ₹1.08 crore, depending on the variant and city.

The E-Class in India is offered in three main variants: the E 200 LWB (petrol), E 220d LWB (diesel), and the top-spec E 450 4MATIC LWB (petrol).

The E-Class is available with a 2.0-litre turbo-petrol (E 200), a 2.0-litre turbo-diesel (E 220d), and a more powerful 3.0-litre twin-turbo petrol (E 450). The petrol and diesel engines offer smooth, efficient performance for daily driving, while the E 450’s larger twin-turbo setup delivers strong acceleration and effortless overtaking, giving a sportier feel on highways.

The E-Class sold in India is the Long Wheelbase (LWB) version, offering a significantly extended cabin with class-leading rear-seat space and comfort, making it a popular choice for chauffeur-driven owners. Rear passengers get plenty of legroom and headroom, plus a serene, luxurious environment that makes long drives or traffic jams feel much more relaxing.

The ARAI-certified mileage of the E-Class ranges from 12 kmpl to 15 kmpl, with the diesel variants generally being more fuel-efficient.

The E-Class has a boot space of 540 litres, which is practical for both daily use and long-distance travel. It can easily fit around three to four large trolley bags along with a couple of smaller duffle bags, making it ideal for family trips or airport runs without worrying about space.

All variants of the E-Class are equipped with a 9-speed G-Tronic automatic transmission. Gear shifts are smooth and barely noticeable, helping the car feel effortless in city traffic while also delivering quick, responsive performance on highways.

Yes, the Mercedes-Benz E-Class comes with a panoramic sunroof.

The E-Class has a ground clearance of approximately 183 mm, which is higher than many of its rivals and is well-suited for Indian road conditions.

The E-Class has a strong safety record with a 5-star Euro NCAP rating. It is equipped with multiple airbags (up to 8 in some variants), ABS with EBD, electronic stability control, and a suite of advanced driver-assistance systems (ADAS) like automated emergency braking.
