BMW 7 Series special

Dedicated to efficiency: luxury meets sustainability

A responsible approach to the environment and the judicious use of resources are pivotal issues of our time. For products in the highest luxury class, such as the new BMW 7 Series, the bar is set particularly high.

For BMW, it is an approach that has been a fundamental tenet for decades. More than 50 percent of electric power used by BMW worldwide derives from renewable sources. To achieve maximum efficiency in the production of the new BMW 7 Series at Plant Dingolfing with its numerous innovative processes, the factory planners redesigned large parts of the facility. This ongoing commitment to saving resources is recognized in international rankings such as the Dow Jones Sustainability Index: BMW is the only vehicle manufacturer to have made it into the top three of these listings for 15 consecutive years. Sustainability is firmly anchored in every area of the company – as evidenced by every single vehicle produced and reflected in every department, from development and production all the way to delivery.

The new BMW 7 Series is the latest example in a sequence of advanced vehicles that – notwithstanding their superlative standards and outstanding capability – gladly play their part in reducing emissions. Here, the luxury sedan benefits from decades of experience with BMW EfficientDynamics and the exceptional development of the innovative BMW i models.

Carbon-fiber-reinforced plastic (CFRP) is extremely strong and ultra-lightweight, and – depending on the alignment of the fibers – boasts significant tensile and flexural strength. One benefit is to improve fuel consumption in the new BMW 7 Series.

A new dimension in lightweight design

Deep inside the exterior body of the new BMW 7 Series lies a powerful innovation. Key elements of the luxury sedan’s body structure consist of lightweight carbon- fiber. The complex expertise required to process this innovative material derives from the development of the BMW i3 and BMW i8 models – because when it comes to the all-electric car for megacities and the hybrid sports vehicle, every ounce of weight counts. Today, no other manufacturer worldwide integrates carbon-fiber to the same extent and uses comparably advanced processes. The body frame of the new BMW 7 Series contains up to 14 carbon-fiber elements. Despite their weight advantage over steel – being lighter by up to 50 percent – they are extremely robust.

This, along with many other lightweight design measures in the new BMW 7 Series, saves nearly 200 pounds compared with its predecessor. As ever, the engineers paid close attention to key factors affecting the BMW driving experience, such as a lower center of gravity, a balanced axle load distribution and a particularly lightweight chassis. In parallel, they developed entirely new processes for the sophisticated production of many lightweight components and the complex mix of highly diverse materials used, for instance, in the vehicle’s Carbon Core. In alliance with honed aerodynamics and an ultra-efficient power unit, the new BMW 7 Series is thus able to post leading figures in terms of both fuel economy and driving dynamics.

Luxury and effortless authority

Engines form the core of every BMW and they epitomize the BMW EfficientDynamics strategy in a way no other element of the vehicle does. In the new BMW 7 Series, they convey a sense of luxury and effortless authority. The BMW Sedan comes with a range of engines that are either brand new or have undergone an extensive overhaul. Powerplants such as the inline six and V-8 have long since been recognized as the finest in their class – as reflected in their numerous international awards.

The sum of BMW expertise: the luxury sedan benefits from decades of experience with BMW EfficientDynamics and the exceptional development of the innovative BMW i models.

In the luxury segment in particular, customers value the responsible use of resources and moderate consumption figures. Thanks to the state-of-the-art TwinPower Turbo technology package with its combination of turbocharging, direct injection and fully variable power management, all engines live up to these expectations while ranking among the most powerful in their category. The new six-cylinder engine, for instance, produces 320 hp and a peak torque of 330 lb-ft, enabling it to propel the new BMW 740i to 60 mph in 5.4 seconds.

Sensationally good figures

Starting in Summer of 2016, the first BMW 7 Series with eDrive will take efficiency to even greater heights. The BMW 740e will feature a gas engine paired with an electric motor. Thus equipped, the 7 Series with eDrive will emit no more than 79 grams of CO2 per mile, a sensationally low figure unmatched by any other comparable model of this size. When a fully charged battery, the hybrid can cover up to 25 miles on electric power alone - sufficient for most urban journeys. For all this, the Sedan will continue to be extremely dynamic to drive.
