The new BMW 7 Series. Start orders in Romania


Just a few months after the world premiere of the electric BMW i7, more powertrain options will be available from November 2022.

Two plug-in hybrid (PHEV) variants – including the first BMW M model in the new BMW 7 Series range – will be available from the engine list. It is a gasoline engine with six cylinders in line and an updated electric propulsion system. The new BMW 740d xDrive means a six-cylinder in-line diesel engine with 48V mild-hybrid technology.

Starting price for Romania for the 740d version it is 90,300 Euros without VAT (107,457 Euros with VAT). Authorized BMW dealers can take orders from today (September 29).

The propulsion systems installed in the two plug-in hybrid models combine a six-cylinder in-line engine with BMW TwinPower Turbo technology and an electric motor integrated into the eight-speed Steptronic transmission. For both models, the power generated by the two power units is transferred to the road via the intelligent BMW xDrive all-wheel drive system.

The electric motor fitted in the two models features the latest generation of BMW eDrive technology for plug-in hybrid models. The synchronous motor with a specific power of more than 5.0 kW/kg has a nominal output of 145 kW/197 hp in the two PHEV variants, and the rev range has been extended to a maximum of 11,500 rpm.

In addition, a gear reduction gear is used to increase the torque produced by the electric motor to an effective maximum of 450 Nm at the engine-side transmission input.

The new BMW M760e xDrive is the first performance car from BMW M GmbH with a plug-in hybrid drive system

The thermal engine is a 3.0-liter, six-cylinder in-line engine with M TwinPower Turbo technology, a rated output of 280 kW/380 hp and a rated torque of 520 Nm. This is combined with a new electric motor to generate a system power of 420 kW/571 hp (with temporary increase) and a system torque of 800 Nm. The above figures translate into an acceleration from 0 to 100 km/h in 4.3 seconds and complete acceleration in half (from 80 to 120 km/h, fifth gear) in just 2.7 seconds. Hereby, the BMW M760e xDrive combines outstanding performance attributes with the option of local emission-free driving pleasure in urban areas and beyond. The M-specific design features, interior trim and cockpit screens perfectly match the sedan’s modern luxury feel.

The the new BMW 750e xDrive, the new electric propulsion system is again combined with a 3.0-liter inline six-cylinder engine, this time developing a maximum power of 230 kW/313 hp and a torque of 450 Nm. Working in tandem, the two power sources produce a system power of 360 kW/490 HP (with temporary boost) and a system torque of 700 Nm. This allows the new BMW 750e xDrive to accelerate from 0 to 100 km/h in 4.8 seconds, and acceleration in half (80-120 km/h) is achieved in just 2.7 seconds.

The electric motors for the two plug-in hybrid models are supplied with energy from a high-voltage lithium-ion battery installed in the floor of the car. At 18.7 kWh, the usable energy content of the battery is more than 50% higher than that available with the previous generation of technology.

The maximum AC charging power is 7.4 kW. In combination with the efficiency of the electric motor and intelligent energy management, including adaptive recuperation, this gives the new BMW M760e xDrive an electric range of 77-85 kilometers (provisional values) in the WLTP cycle, and the new BMW 750e xDrive a range of 78- 87 kilometers (provisional values) according to WLTP.

Diesel engine with six cylinders in line, with latest generation 48V mild-hybrid technology

The consistent progress made under the BMW EfficientDynamics development program also benefits the new diesel engine for the BMW 7 Series. In the new BMW 740d xDrive, a completely updated combustion engine teams up with the latest 48 V mild-hybrid technology, which includes an electric motor integrated into the eight-speed Steptronic transmission. The result is a maximum power of 220 kW/300 hp (generated by the combination of the thermal engine with up to 210 kW/286 hp and the integrated electric motor with up to 13 kW/18 hp) and the maximum torque of 670 Nm (generated by the engine combination thermal up to 650 Nm with the integrated electric motor up to 200 Nm).

The 3.0-liter inline six-cylinder diesel engine that powers the BMW 740d xDrive has new steel pistons that allow an increase in injection pressure and enrich the engine’s acoustics. The efficiency of the oil separation process has also been improved compared to the predecessor engine. The new common-rail direct injection system now works with solenoid valve injectors, providing up to 12 injections per power stroke with a maximum pressure of 2,500 bar.

The latest generation of mild-hybrid technology ensures that extra power is instantly available and the level of recuperation is high to improve efficiency. The electric motor is integrated – together with the power electronics – in the housing of the eight-speed Steptronic transmission, where it also assumes the role of a starter.

This allows coasting with the complete shutdown of the internal combustion engine over long distances and a smooth and efficient restart. The rapid power delivery of the electrified drive system enables acceleration from 0 to 100 km/h in 5.8 seconds. In addition, the high-precision interaction between the thermal engine and the electric motor improves the efficiency and fluidity of the propulsion system, making it ideal for use in the new BMW It would be 7.
