Ως EfficientDynamics αυτοκίνητο διαθέτει σύστημα Start/Stop, σύστημα ανάκτησης ενέργειας κατά το φρενάρισμα, ενεργή γρίλια, αεροδυναμικές ζάντες και κιβώτιο ταχυτήτων με μακριές σχέσεις κάνοντας έτσι την κατανάλωση να περιορίζεται στα 4.5 λίτρα/100 χλμ με εκπομπές CO2 119 γρ/χλμ.
Τέλος η BMW ανακοίνωσε ότι η 5-Series θα είναι διαθέσιμη και με τον 2.0-λιτρο TwinPower Turbo κινητήρα. Η έκδοση 520i αποδίδει 184 άλογα με 270 Νμ ροπής με τα 0-100 χλμ/ώρα να τα κάνει σε 7.9 δευτ. με τελική ταχύτητα 227 χλμ/ώρα. Τέλος η έκδοση 528i φορά και αυτή τον 2.0-λιτρο κινητήρα απόδοσης 245 ίππων με 350 Nm ροπής. Τα 0-100 χλμ/ώρα τα κάνει σε 6.2 δευτ. με τελική ταχύτητα 250 χλμ/ώρα.

BMW 520d EfficientDynamics Edition: unique in the upper mid-range segment – a premium sedan with CO2 emissions of 119 g/km.
From autumn 2011, in parallel with the regular BMW 520d, an ultra-fuel-efficient version of this sedan will be offered: the BMW 520d EfficientDynamics Edition. With unchanged maximum power (135 kW/184 hp) and torque (380 Newton metres / 280 lb-ft), this model records average fuel consumption in the EU test cycle of 4.5 l/100 km (62.8 mpg imp) and CO2 emissions of 119 grams per kilometre. This is around ten per cent better consumption than the most fuel-efficient segment competitors, despite the fact that the BMW 520d EfficientDynamics Edition is more powerful than the competitor models.
With a 0-100 km/h (62 mph) acceleration time of 8.2 seconds and a top speed of 231 km/h (143.5 mph), even this most fuel-efficient model in the BMW 5 Series boasts typical sporty BMW performance. Its extra-efficient 2.0-litre diesel engine is, like that of the familiar BMW 520d, equipped with a centrifugal pendulum absorber which reduces irregular running at low engine speeds for greater refinement. It is also combined with a range of other efficiency-enhancing measures. These include Auto Start-Stop, an Optimum Shift Indicator, Brake Energy Regeneration and active cooling flap control, plus a longer final drive ratio and special aero rims with “Streamline” styling.
New four-cylinder petrol engines with BMW TwinPower Turbo technology.
With the launch of a new generation of four-cylinder engines with BMW TwinPower Turbo technology, the BMW 5 Series engines for the upper mid-range market now lead the way on efficiency and sporty power delivery in the petrol segment too. This world-exclusive technology equips the two 2.0-litre engines with twin-scroll turbocharging, High Precision Injection direct injection, VALVETRONIC variable valve timing and Double-Vanos variable camshaft timing. This combination of features is inspired by the technology package used on the multi-award-winning 225 kW/306 hp six-cylinder in-line BMW TwinPower Turbo engine of the BMW 535i. Now BMW has adopted this highly efficient performance-boosting technology in the four-cylinder engines as well. The system, which delivers the exhaust gases from each pair of cylinders to the turbine via two separate channels, both in the exhaust manifold and in the turbocharger itself, provides more responsive performance. The fuel supply is precisely metered by the direct-injection system with solenoid injectors, while the latest version of the VALVETRONIC system provides even more precise air mass control and, in combination with Double-Vanos variable intake and exhaust camshaft timing, optimises both efficiency and response.
As fitted in the new BMW 520i, the four-cylinder engine develops maximum power of 135 kW/184 hp at 5, 000 rpm and peak torque of 270 Newton metres (199 lb-ft), which is available between 1,250 and 4,500 rpm. Instantaneous power response helps the BMW 520i Sedan perform the 0 to 100 km/h (62 mph) sprint in 7.9 seconds (automatic: 8.0 seconds), while the BMW 520i Touring accomplishes the same task in 8.3 seconds (automatic: 8.4 seconds). Top speeds are 227 km/h (141 mph) (automatic: 226 km/h / 140.4 mph) for the Sedan and 220 km/h (36.7 mph) (manual and automatic) for the Touring model. Simultaneous efficiency improvements are reflected in average fuel consumption (as per EU test cycle, depending on tyre format) of 6.8 – 7.0 l/100 km (40.3 – 41.5 mpg imp) (automatic: 6.5 – 6.7 litres / 42.2 – 43.5 mpg imp) and CO2 emissions of 157 – 163 grams (149 – 155 grams) per kilometre. For the BMW 520i Touring, the corresponding figures are 7.0 – 7.3 l/100 km (38.7 – 42.2 mpg imp) (automatic: 6.7 – 7.0 litres / 40.3 – 42.2 mpg imp) and 163 – 170 grams (automatic: 156 – 163 grams) per kilometre.
In the new BMW 528i, with modified turbocharging and injection technology, the four-cylinder engine develops maximum power of 180 kW/245 hp at 5,000 through 6,500 rpm, and peak torque of 350 Newton metres (258 lb-ft), which is available between 1,250 and 4,800 rpm. 0 to 100 km/h (62 mph) is accomplished in 6.2 seconds for the new BMW 528i Sedan (automatic: 6.3 seconds), and 6.4 seconds for the BMW 528i Touring (automatic: 6.6 seconds). Top speeds are 250 km/h (155 mph) for the Sedan and 244 km/h (151.6 mph) for the Touring model (in both cases the figures are the same for both manual and automatic versions). The new BMW 528i Sedan achieves average fuel consumption (as per EU test cycle, depending on tyre format) of 6.8 – 7.1 l/100 km (39.8 – 41.5 mpg imp) (automatic: 6.5 – 6.8 litres / 41.5 – 43.5 mpg imp), and CO2 emissions of 159 – 165 grams (automatic: 152 – 158 grams) per kilometre. For the new BMW 528i Touring, the corresponding figures are 7.1 – 7.4 l/100 km (38.3 – 39.8 mpg imp) (automatic: 6.8 – 7.1 litres / 39.8 – 41.5 mpg imp) and 165 – 172 grams (automatic: 159 – 166 grams) per kilometre.
