M340i xDrive Price and Specs, BMW 3 Series

The M340i is the performance flagship of the 3 Series, priced at ₹77.10 Lakh. It swaps the 2.0 litre four for a 3.0 litre TwinPower Turbo inline-six petrol making 369 bhp and 500 Nm. That is a big step over every other trim here, and it seats five.

Peak torque of 500 Nm holds from 1,900 to 5,000 rpm, and power keeps building to 6,500 rpm, so the six pulls hard everywhere. The trade-off is economy, with a claimed 13.02 kmpl, the lowest in this line-up. The exact equipment is not listed in our data, so confirm the full specification through the on-road price enquiry.

Choose the M340i if you want the fastest, most special 3 Series and can live with higher fuel bills. It costs around ₹14 Lakh more than the 330Li M Sport, reflecting the extra cylinders and power. If speed is not the priority, the four-cylinder petrol and diesel trims make more financial sense.
