Volkswagen will be showcasing its latest “green” models at this month’s Frankfurt Motor Show with the unveiling of the the new generation of the Polo BlueMotion, Golf BlueMotion and Passat BlueMotion. According to VW these three cars are the world’s “most fuel-efficient” models in their respective segments.
Key features of these cars are new common rail TDI engines with modified engine management software and reduced idling speed. Furthermore power transfer is handled by five-speed gearboxes with longer gear ratios. There is also a gear-shift indicator integrated in the instruments ensures that the BlueMotion models are always driven at the gear stage that is optimal for fuel economy.
Other BlueMotion characteristics include energy recovery (regenerative braking), a start-stop system (automatic engine shutoff, such as at red lights), tyres optimised for low rolling resistance, especially lightweight low-drag wheels, improved fine tuning of body aerodynamics and a lower chassis (Polo and Golf).
