The BMW 7 Series specifications describe a single car, the 740i M Sport. Its engine is a 3.0 litre inline six turbo petrol with a mild hybrid. Output is 400 PS, quoted as 394 bhp, with 540 Nm of torque. An eight speed automatic drives the rear wheels. Peak power spans 5200 to 6250 rpm.

The 48 volt mild hybrid assists the engine at low speed. It cannot move the car on electricity alone. Peak torque runs from 1850 to 5000 rpm, so the flagship pulls without fuss. The engine is a smooth straight six, a BMW signature. BMW rates it at 12.61 kmpl on the ARAI cycle. A large, heavy sedan with a big engine will read lower in town. See what that means for real running cost.

The dimensions explain the limousine feel. Length is a long 5391 mm on a 3215 mm wheelbase. Width is 1950 mm and height 1544 mm, giving real presence. The long wheelbase is what creates the rear cabin space. It also smooths the ride over broken surfaces. Ground clearance is 136 mm, tuned for smooth roads rather than rough ones.

The 74 litre tank suits long trips between fills. The 540 litre boot is generous for a sedan this focused on the back seat. Seating is for five, though the rear pair travel best. Six paint finishes are offered, from Mineral White to Vancouver Green. The M Sport package comes as standard on the sole trim. Comfort and cabin technology sit at the top of the range.

BMW 7 Series power and torque explained

In India the 7 Series comes with just one engine, but it is a strong one. You get a 3.0 litre inline-six turbo petrol backed by a 48 volt mild hybrid, making 400 PS and 540 Nm. It is set up for calm, effortless pace rather than drama, which suits a flagship built around the rear seat.

That single choice means the complete 7 Series rundown can spend its time on trim, comfort and price rather than engines.

How to read this chart. Torque is the push you feel when you accelerate, and it peaks low on the rev range. Power is how hard the engine keeps pulling as it revs higher, and it peaks further up. The two dots mark those peaks. The shaded strip between them is the flexibility band: a wider band pulls easily across more revs and feels relaxed in traffic, while a narrower band asks you to rev the engine more to get its best.

Peak figures come from the 3.0L Inline-6 Turbo Petrol Mild Hybrid spec sheet. The line between the two peaks is not a measured dyno curve.

The 3.0 turbo petrol makes its full 540 Nm as low as 1850 rpm, so the car eases away gently and glides through traffic. You rarely have to work it, which is just what you want with someone sitting in the back. When you press on, power keeps building to 400 PS at 5200 rpm, so highway overtakes come easily whenever you ask. The mild hybrid smooths the low-speed crawl, and its fuel economy figures show how that pays off. For a big, comfort-first flagship, this single engine handles city runs and long trips without ever feeling stretched.
