According to German publication Autobild, the next generation 2016 BMW 5 Series will be offered with a three-cylinder engine. Same outlet says the next M5 will receive an xDrive option.
A little bit of background on the three-cylinder engines from BMW.
The three-cylinder unit was first revealed in 2012. The “Baby-Six,” a 1.5 liter three-cylinder turbocharged engine, is built on the 500cc per cylinder architecture. The compact engine has the same genes as the award-winning 3.0 liter six-cylinder unit. The 1.5 liter three-cylinder uses a mono-scroll that keeps the load step at steady 1,500 rpm.
BMW will offer a range of power outputs, low, mid and high, based on the configuration of the car and of course, its weight. For gasoline, the power range starts at 30 kW and extends to 50 kW per cylinder. A little math gives us a range in horsepower from 120 to approximately 200 ponies. For diesels, the low end of the char shows 20 kW per cylinder or 80 horsepower per engine. At the high end, 180 ponies will drive the diesel-powered vehicle. The torque ranges are 180 to 270 Nm for petrol, and 225 to 300 Nm for diesel.
At the time, BMW experts said to not expect a 2,000 kg vehicle to be moved by a 1.5 liter engine, but since the new generation 5 Series will go through a “weight loss”, that statement might be obsolete.
Autobild says that the 2016 5 Series will be offered with a small 3-cylinder turbodiesel producing 150 HP (110 kW), delivering a fuel consumption of just 3.9 liters / 100 km (60 mpg US or 72 mpg UK).
The new 5-Series will go on sale as a sedan in July 2016, followed by the Touring and second generation 5 Gran Turismo.
Now onto the next M5. While in the past the M folks have constantly dismissed the idea of an all-wheel drive M5, recent reports indicate that the next BMW M5 will get an optional xDrive. The power output is said to be raised to over 600 horsepower.
