The new Volkswagen Golf BlueMotion offers fuel economy of 88.3mpg on the combined cycle and emissions of just 85g/km CO2.
The fuel economy is 15 per cent better than that of the previous-generation model, which emitted 99 g/km (now the emissions of a standard Golf 1.6-litre TDI). The original Golf BlueMotion, revealed at the Geneva Motor Show in 2007, returned, at that time, a class-leading 62.8 mpg with emissions of 119 g/km – figures now surpassed by even the range-topping diesel, the 184 PS Golf GTD.
With its 50-litre fuel tank and 88.3mpg fuel consumption, the new Golf BlueMotion has a theoretical range of 970 miles. Assuming an average annual driving distance of under 10,000 miles, most drivers will only have to refuel 10 times a year. The Golf BlueMotion is in Band A, meaning that there’s nothing to pay for road tax.
The reduction in the car’s combined fuel consumption has been achieved through lightweight design (including 26 kg less weight in the running gear and 37 kg less in the body), engine-related modifications and a collection of other measures. These include super low rolling resistance tyres with higher air pressure, longer gear ratios (six-speed manual gearbox), the Stop/Start and battery regeneration systems that are standard in all new Golfs, plus specific aerodynamic modifications.
The frontal area of the new Golf was reduced by 0.03 m 2 and aerodynamic drag (Cd x A) by nearly 10 percent, giving it a Cd value of 0.27. Compared to other standard Golf models, the aerodynamics of the BlueMotion were also refined by a lowered ride height (by 15 mm), a roof spoiler, lateral air guide elements on the rear window, a masked front grille, partially closed air inlet screens, optimised cooling system airflow, special underfloor panels, optimised brake cooling channels and a C-pillar spoiler.
At the heart of the new Volkswagen Golf BlueMotion is a 1.6-litre 110 PS common rail TDI producing 5 PS more power than in non-BlueMotion models. The four-cylinder 16-valve unit develops its maximum torque of 250 Nm from just 1,500 rpm up to 3,000 rpm.
Various measures such as reduced internal friction, an innovative thermal management system with shortened warm-up phase, exhaust gas recirculation, cylinder pressure sensor, two-stage oil pump, switchable electric water pump and water-cooled intercooler right in the intake manifold result in successfully reducing fuel consumption and emissions. To reduce emissions values further, Volkswagen has also implemented an oxidation catalytic converter, a diesel particulate filter and a NOx storage catalytic converter.
Prices for the new Golf BlueMotion start at £20,335 for the three-door and rise to £20,990 for the five-door, with specification based on that of the standard Golf S. UK Volkswagen Retailers are taking orders for the new Golf BlueMotion now, with the first deliveries expected in August.
