BMW includes 4WD model in new 7 series hybrid line

POSTED BY Nigel Andretti ON 20 julai 2016

BMW has introduced its three 7 Series plug-in hybrid luxury sedans: the 740e iPerformance, 740Le iPerformance, and the 4WD 740Le xDrive iPerformance.

The trio is powered by the latest-generation four-cylinder gasoline engine with BMW TwinPower Turbo technology and an electric motor. bersama-sama, they deliver a system output of 326hp.

The new BMW 740e iPerformance with standard wheelbase and the new BMW 740Le iPerformance with long wheelbase offer combined cycle average gasoline consumption of 2.2–2.0 liters per 100 kilometers and CO2 emissions of 50–45 grams per kilometer.

The new BMW 740Le xDrive iPerformance delivers 2.5–2.1 l/100 km with CO2 emissions combined of 56–49 g/km). Intelligent all-wheel drive distributes the combined power of the combustion engine and electric motor permanently and as required between the front and rear wheels.

The electric power consumption of the plug-in hybrid luxury sedans, as calculated in the EU test cycle, stands at 13.3-12.5 kWh per 100 kilometers for the BMW 740e iPerformance and 13.3-12.6 kWh per 100 kilometers for the BMW 740Le iPerformance.


The combined electric power consumption of the BMW 740Le xDrive iPerformance in the EU test cycle comes in at between 13.9 dan 13.2 kWh per 100 kilometer.

The maximum electric range, as per the EU test cycle for plug-in hybrid vehicles, adalah 44-48 kilometers for the BMW 740e iPerformance and BMW 740Le iPerformance, atau 41-45 kilometers for the BMW 740Le xDrive iPerformance.

The combustion engine with BMW TwinPower Turbo technology employed by the plug-in hybrid variants of the new BMW 7 Series is a member of the new Efficient Dynamics engine family. Developing maximum output of 258 hp, it is the most powerful four-cylinder engine ever fitted in a series-produced BMW.

Instantaneous power delivery and peak torque of 400 Nm on tap across a wide rev range (1,550-4,400 rpm) give the 2.0-litre unit sporty yet poised and authoritative performance. Sebagai tambahan, the new engine displays outstanding refinement.

The electric drive system, based on the principle of a permanently excited synchronous motor, delivers a high power density with a maximum output of 83 kW/113 hp. As is characteristic for electric drive systems, it serves up its peak torque of 250 Nm instantly. The electric motor also takes on the role of a generator which—depending on the hybrid function selected — is powered either by recuperating braking energy or by efficiently raising the engine’s load points. It then feeds the energy it generates into the high-voltage battery.

The electric motor is fully integrated into the eight-speed Steptronic transmission. This ensures that pure-electric driving, the dynamics-enhancing electric boost function and the recuperation of braking energy are all efficient.

Working together intelligently, the combustion engine and electric drive system deliver a system output of 326 hp and a combined peak torque of 500 Nm.

The BMW 740e iPerformance accelerates from 0 kepada 100 km/h in 5.4 saat; the BMW 740Le iPerformance to completes the same sprint in 5.5 saat.

The BMW 740Le xDrive iPerformance is the brand’s second model to distribute its power permanently to all four wheels in pure-electric driving, when the combustion engine cuts in and when both drive systems are in use at the same time.

Power distribution between the front and rear wheels gives the BMW 740Le xDrive iPerformance extremely dynamic accelerative ability, with the journey from rest to 100 km/h completed in 5.3 saat.

A multiple driving mode button – now known as a Driving Experience Control switch – on the centre console offers four modes (Eco Pro, Comfort, Sport and Adaptive) that are, according to BMW, much more clearly defined.

The Adaptive mode reads the driver’s inputs and terrain travelled to optimise the 740’s consumption of fuel and battery power, which can be replenished by regenerative braking, petrol engine recharging or by plugging into the mains.

BMW claims the battery can be fully recharged from a regular wall socket in four hours, while a BMW i Wallbox will do the job in three hours.

yang 7 Series is built around BMW’s Carbon Core – first seen in the i8 hybrid sportscar – that comprises a mixture of steel, aluminium and carbon-fibre reinforced plastic (CFRP) for the platform and chassis, netting a weight reduction of up to 130kg over the old model, according to BMW.

Standard equipment for all three variants will include LED headlights, a BMW Display Key, a ConnectedDrive navigation package, smartphone integration with inductive charging facility for the phone battery, a touchscreen-enabled iDrive system and gesture control.

A new remote heating and air conditioning system, which allows owners to prepare the car’s interior temperature in advance, will be offered, and is powered from the high-voltage battery. When the car’s battery is being charged, the auxiliary air-conditioning function is powered by the mains supply.

Driver assistance systems include a head-up display as well as the parking assistant, driving assistant, driving assistant plus and surround-view systems.

The iPerformance variants of the new BMW 7 Series can also be specced with an M Sport package, Pure Excellence exterior design and interior design packages and BMW’s Individual Design Composition.
