The new generation of the flagship BMW 7 Series sedan will be equipped with new petrol engines. This is in particular a heavily upgraded version of the 3.0-liter (B58) in-line six-cylinder petrol engine.
The BMW 7 Series will be completely overhauled for the 2023 model year with a redesign likely to bring split headlights, an all-electric version and, according to a new report, new gasoline engines. While electrification will be in the spotlight when it comes to powertrains, there is good news for ICE enthusiasts, but these are just rumors.
The BMW Blog reports that the base 7 Series will receive a heavily redesigned version of the 3.0-liter (B58) in-line six-cylinder petrol engine.
In the 735i it will put out about 270 horsepower, while if you choose the 740i it will produce 370 horsepower. Of course, these are not official figures yet.
As a side note: The refreshed B58 engine is expected to be offered on the X5, X6 and X7 as well, but will likely debut on the 2023 7 Series. The 5 Series, with 540i trim, is also set to receive a new version of BMW’s 3.0-liter inline-six at some point.
While the refreshed B58 will undoubtedly be warmly received, BMW fans are likely to be more excited by the news that the new V8 will debut with the new 7 Series. It is expected to carry the internal designation S68, it will be based on the existing 4.4-liter twin-turbo V8 N63 and will have some standard hybridisation. According to the BMW Blog, power should be around 535bhp and, like the new 3.0, it should be expanded to other major models of the company.
The all-electric version of BMW’s flagship sedan will admittedly be the most technologically advanced model in the new 7 Series. According to preliminary data, it can have a power of up to 650 hp. with a large battery and twin motors driving all four wheels, making it the most powerful option in the range.
