The BMW 528i will have its six-cylinder engine replaced with a new four-cylinder TwinPower Turbo two-litre petrol engine, an uprated version of the one found in the 520i, delivering 180 kW (5,000-6,500 rpm) and 350 Nm of torque (1,250-4,800 rpm).
When it comes to performance, going from a six to a four-cylinder engine has had the opposite effect as the new 528i is actually faster than before. Now accelerating from 0-100km/h in a very sporty 6.3 seconds (0.4 seconds faster than the six-cylinder 528i).
The 528i's fuel consumption figures have also dropped to 6.7L/100km (below the luxury car tax threshold) meaning prices now start from $98,200 (previously $99,900). BMW has added dynamic driving control, ECO PRO mode, electric seat adjustment, professional navigation system, automatic start/stop function and on-board internet functionality as standard equipment for no extra cost.
If you want a diesel, the entry model 520d now retails for $80,700 (previously $83,300) and sips just 4.7L of diesel per 100km. Our favourite in the range, the 3.0-litre twin turbo 535d (now $120,900), has seen its power increase to 230kW meaning it now accelerates from 0-100km/h in 5.5 seconds and yes it's a diesel, so fuel consumption remains at a ridiculously low 5.6L/100km. What other car can you think of that can do the 0-100km/h dash in 5.5 seconds or less and uses just 5.6L/100km?
For those still stuck in the old ways demanding a powerful petrol, the 535i is the one to go for, now retailing for $115,600 and hitting 100km/h from a standstill in 5.9 seconds.
If you simply can't wait for the new BMW M5, the current range-topping TwinPower turbo V8 petrol 550i sedan still remains at the same price point ($179,900) but gains about $3,000 worth of added features.
BMW Australia has also added its new Active Protection safety system to the 2012 range. The safety package quickly initiates protective measures for occupants when it detects an accident is imminent. This means belt tensioning, closing the windows and sunroof as well as positioning the front-passenger backrest to a crash-optimised location.
The 2012 BMW 5 Series update is certain to entice even more interest in the German offering, with the outgoing model already the best selling car in its segment (37 percent marketshare).
