The biggest change that has taken place in the new 5-Series edition is the launch of a standard 4-cylinder turbo engine under the bonnet, substituting the previous 3-liter 6-cylinder engine.
In an attempt to increase the fuel efficiency, German based BMW Motors has introduced a standard 2-liter inline 4-cylinder turbocharged engine, which has the capability to pull out an impressive 240-hp and torque of about 260 pound-feet.
The engine has been mated to a standard 8-speed auto gearbox system, which has the ability to offer smooth power transmission to the wheels.
Looking at the real figures, the new 4-cylinder equals or even slightly surpasses the bigger 6-cylinder in many areas of concern, but many consumers still have a nagging feel that a vehicle that costs nearly more than $60k should incorporate something more potent under its hood.
The new 4-cylinder beats the 6-cylinder when it comes to 0-60 match-up. The company claims that the 4-cylinder vehicle can sprint from 0 to 60 mph in under 6.2-seconds, which tops the old 6-cylinder model by nearly a half-second.
The EPA fuel economy estimations of the 2012 528i xDrive model with 4-cylinder engine has been rated to vary in between 22 and 32 miles per gallon, which is nearly about 2-percent improvement over the previous 6-cylinder engine.
