Volkswagen Unveils New Golf BlueMotion Concept; 62 mpg US, 99 g CO2/km

|The Golf BlueMotion concept.|
Volkswagen unveiled the BlueMotion concept version of its coming new sixth-generation Golf. The Golf BlueMotion concept has combined European cycle fuel consumption of 3.8 L/100km (62 mpg US) and CO2 emissions of 99 g/km. This matches the economy of the Polo BlueMotion, itself among the most efficient conventional vehicles currently on sale. (Earlier post.)
The new Golf BlueMotion concept is powered by a 1.6-liter TDI common rail diesel engine developing 77 kW (104 hp) and 249 Nm (184 lb-ft) of torque at 2,000 rpm. Acceleration from 0 to 62 mph is 11.3 seconds; top speed its 117 mph. In common with every diesel model in the forthcoming new Golf range the BlueMotion concept is fitted with a diesel particulate filter.
As with all BlueMotion models, the Golf BlueMotion adopts a series of changes to drivetrain and aerodynamics in order to maximize the vehicle’s efficiency. A set of low rolling resistance tires are joined by optimized aerodynamics and revised ratios in the five speed gearbox. The resulting combination of changes works to reduce loading on the engine to drive up economy and reduce emissions.
The BlueMotion label was first attributed to the Polo in 2006 and represents the most efficient model in each of Volkswagen’s passenger car ranges. Since the Polo made its debut, BlueMotion versions of the Golf Mk V, Golf Estate, Golf Plus, Jetta, Touran, Passat, Passat Estate and Sharan have been launched.
The new Golf. The sixth generation of the Golf, which launches into the market in October, features a range of new diesel and gasoline engine and transmission technologies that reduce fuel consumption by up to 28% compared to the previous generation. All gasoline and diesel engines fulfill emission limits of the future Euro-5 standard.
On the diesel side, the Golf is using common rail TDI engines for the first time. Plans call for a TDI power range from 66 - 125 kW (89-168 hp). At market launch, Volkswagen will offer two 2.0 liter TDI engines on the Golf, delivering 81 kW (108 hp) and 103 kW (138 hp). The 81 kW diesel has a fuel consumption rating of 4.5 L/100km (52 mpg US) and emissions of 119 g CO2/km—a reduction of 0.6 liter compared to the previous generation. The 103 kW diesel has a fuel consumption rating of 4.9 L/100km (48 mpg US) and 129 g CO2/km —also 0.6 liter less than the on the previous generation.
In the launch phase, Volkswagen will offer four gasoline engine variants: 59 kW (79 hp), 75 kW (101 hp), 90 kW (121 hp) and 118 kW (158 hp). Starting at the 90 kW level, VW will use TSI engines with supercharging and/or turbocharging are used.
The optimized 59 kW entry-level engine consumes 6.4 L/100km (37 mpg US)—0.5 liter less than its predecessor. The new Golf 90 kW 1.4 TSI consumes 6.2 L/100km (38 mpg US)—a fuel consumption advantage of 0.1 liters. The new 118 kW top version of the 1.4 TSI offers consumption of 6.3 L/100km, reducing fuel consumption by 1.6 liters compared to the retired 110 kW FSI.
With the exception of the entry-level versions, all gasoline and diesel engines in the new Golf range may be paired with Volkswagen’s dual clutch transmission (DSG). Either a 6-speed or 7-speed DSG is used, depending on engine torque. The combination of DSG and TSI engines helps optimize fuel economy. The 118 kW 1.4 TSI and 7-speed DSG consumes 6.0 L/100km (39 mpg US, 139 g/km CO2). This replaces the 110 kW 2.0 FSI and 6-speed automatic, which offered average fuel consumption of 8.3 L/100km (28 mpg US); the savings of 2.3 L/100km represents a 28% improvement.
Volkswagen has sold more than 26 million Golfs since the original introduction of the vehicle to the market in 1974.
