The all-new BMW 750d won’t get the now familiar tri-turbo six-cylinder diesel engine, but according to a new report, a four-turbo variant that’s set to debut next year, and which is said to bear the codename ‘B57 TOP’.
According to Bimmertoday, it’s not clear whether this fourth turbo will be an actual one or an electric supercharger as is the trend nowadays. Power is believed to be just over 400 hp, while torque will come in at a massive 800 Nm or 590 lb-ft.
The engine will probably be used in the same models the current one is right now: the 5-Series, X5, X6 and future X7 model. All will most likely come with standard xDrive all-wheel drive.
The quickest model currently using the tri-turbo is the M550d, which has 381 hp and 740 Nm of torque. It sends the medium-sized exec sedan to 100 km/h or 62 mph in 4.7 seconds, while promising to use just 6.3 l/100km on the combined cycle.
