BMW has revised the F10 5-Series model range, with these new engines added for the September 2011 production. Most of the updates concern four cylinder engines, but keep reading and there’ll be something for the inline-6 and V8 fans.

First up is a new variant called the BMW 520i, which will feature the new 184hp/270Nm 2.0 litre inline four cylinder engine that was first announced for the X1. The 520i does 0 to 100km/h in 8 seconds.

Next up is an updated 528i, which dumps its 3.0 litre inline-6 engine for a higher powered version of the 2.0 litre turbo four pot in the 520i, thanks to increased boost pressure and a revised fuel injection system. As expected from the power ratings in the X1 and Z4, the new 528i makes 245hp and 350Nm, propelling the sedan to 100km/h in 6.3 seconds.

The oil burner 525d has also got 2 cylinders lopped off but it gains one extra turbocharger – it is now powered by a 2.0 litre four cylinder engine with two turbos, an engine that was previously only found in smaller cars like the 123d. The new four cylinder 525d makes 218hp and 450Nm of torque.

There’s also a new version of the 520d that’s called the 520d EfficientDynamics, which retains the same 184hp/380Nm power output but gets 10% better mileage thanks to low rolling resistance tyres on Streamline design alloy wheels, a longer final drive ratio for lower engine RPM during highway cruising, and a range of other EfficientDynamics features such as Auto Start-Stop, Optimum Gearshift Indicator, Brake Energy Regeneration and Active Aerodynamics.

The 530d and the 535d also gets some revisions to their 3.0 litre turbodiesel inline-6 engines. The 530d now has 13% better fuel consumption, while the 535d gets a power boost up to 313hp, up from 300hp.

The four cylinder and six cylinder F10 now also faetures the new ECO-PRO button, which adjusts engine mapping, throttle sensitivity, automatic gearshift points, where applicable, and the amount of power consumed by electrical ancillaries including climate control and heated seats. We first saw this ECO-PRO button in the new 1-Series.

We’ll update you as soon as any of these changes roll down to our Malaysian market.
