VW unveils 74 mpg Golf BlueMotion Concept

Debuting in concept form today is the most fuel efficient and cleanest version of Volkswagen's sixth-generation Golf. Wearing the BlueMotion badge, as is common for VeeDubs with fuel-saving tweaks, the new Golf is able to complete the European driving cycle mileage tests with a rather epic 74 miles per gallon (around 62 mpg in the U.S. if conversions can be trusted). For those who like to keep track of such things, that's just 99g/km of carbon emissions and an excellent score by any measure. In order to achieve such low fuel consumption and emissions, the Golf BlueMotion is bestowed with a miserly 1.6-liter TDI common rail diesel engine that kicks out 105 horses and 184 lbs.-ft. of torque at a low 2,000 rpm. Low rolling resistance tires, aero tweaks and revised gearing all help the cause. Though still just a concept, there is little doubt that this model or one very similar will debut a few months after the the standard Golf in Europe next year. In the U.S.? Don't hold your breath, though a Golf TDI sold in the States may happen eventually.

PRESS RELEASE:

99 G/KM, 74 MPG: GOLF BLUEMOTION CONCEPT SETS NEW BENCHMARKS

Volkswagen has today unveiled the remarkable Golf BlueMotion concept vehicle, a car capable of achieving a combined 74.3 mpg while emitting just 99 g/km of CO2. This matches the economy of the Polo BlueMotion, itself among the most efficient vehicles currently on sale.

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 BlueMotion concept is powered by a highly-efficient and refined 1.6-litre TDI common rail diesel engine developing 105 PS and 184 lbs ft of torque at 2,000 rpm. Despite the focus on economy the Golf BlueMotion concept can reach 62 mph from rest in a respectable 11.3 seconds before going on to a top speed of 117 mph.

As with all BlueMotion models the Golf BlueMotion adopts a series of changes to drivetrain and aerodynamics in order to maximise the vehicle's efficiency. A set of low rolling resistance tyres are joined by optimised 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.

In common with every diesel model in the forthcoming new Golf range the BlueMotion concept is fitted with a diesel particulate filter.

Even in standard non-BlueMotion form, the new Golf sets new economy standards. The entry-level diesel Golf will be powered by a 2.0-litre TDI 110 PS common rail engine capable of achieving 62 mpg on the combined cycle while emitting 119 g/km of CO2. This matches the economy of the current Golf BlueMotion model.

The new Golf will go on sale in the UK in January next year; the BlueMotion model will follow around mid 2009.
