BMW has unveiled the new 520d EfficientDynamics Edition (EDE).
Designed for eco-minded drivers, the EDE has a 2.0-liter diesel engine with 184 PS (135 kW / 181 hp) and 380 Nm (280 lb-ft) of torque. This enables the car to accelerate from 0-100 km/h in 8.2 seconds and hit a top speed of 231 km/h (144 mph). More importantly, thanks to several enhancements - an engine start/stop system, regenerative brakes, an active grille, a longer final drive ratio and aerodynamic wheels - the model has an average fuel consumption of 4.5 L/100 km (62.8 mpg imp / 52.3 mpg US) and CO2 emissions of 119 g/km.
