BMW is already working on the new generation 7 series, but that does not mean that the current one will not be affected for the rest of its life cycle. Still on sale in many parts of the world, Bavaria’s flagship sedan is getting a new family of in-line six-cylinder diesel engines for the European market, which includes greener and more efficient factories.
This is possible thanks to the addition of a 48-volt electrical system with an integrated starter-generator, which helps acceleration with an increase of 11 horsepower (8 kilowatts). BMW promises to help the new 3.0-liter diesel engines deliver better fuel consumption of between 0.4 and 0.6 liters per 100 kilometers.
From the 730d and 730d xDrive (and their respective long wheelbase versions), these models benefit from an updated six-cylinder in-line diesel with an additional 21 hp (15 kW) for a total power of 286 hp (210 kW ), while the torque increases from 22 foot-pounds (30 Newton-meters) to 479 foot-pounds (650 Nm). With the addition of punch, the two sedans benefit from improved acceleration from 0 to 62 miles per hour (0-100 kilometers per hour) in just 5.9 and 5.6 seconds, respectively.
Moving to the more powerful iteration of the 3.0-liter engine, the 740d xDrive now offers 340 hp (250 kW), up from 20 hp (15 kW) compared to the previous version of the engine. Thanks to this, and the additional 15 lb-ft (20 Nm) at a peak of 516 lb-ft (700 Nm) between 1,750 and 2,250 rpm, the luxury sedan only needs 5.0 seconds to reach 62 mph (100 km / h) from a stop, 0.2 seconds faster than before.
Both engines benefit from a new exhaust gas filtration system with an optimized diesel particulate filter, helping the Diesel 7 series to meet the latest European emission standards Euro 6d. In addition, according to BMW, customers will be offered new customization options for the exterior and interior, including the new BMW Individual Merino leather for the cab in color combination Smoky White / Midnight Blue / Black.
