What is it?
The Golf is the fourth car in the VW range to be given the efficiency-orientated BlueMotion treatment. Unlike the Polo it doesn’t feel like a stripped-out econo-box: the revisions have been added to the existing, well-equipped 1.9 TDI S and Match specs.
The Bluemotion costs £520 more than the standard 1.9 TDI, but it saves £85 in road tax and will be exempt from the London Congestion Charge, sneaking under the 120g/km barrier with CO2 emissions of just 119g/km.
Revisions include harder compound tyres, taller gearing, lower suspension and revised engine management. The front grille aperture has also been partially blanked to reduce drag. Aerodynamic efficiency and rolling resistance are both improved, contributing to the impressive claimed fuel economy.
What’s it like?
Under gentle use, we saw an average of 60mpg – making VW’s combined figure of 62.8 appear achievable. A gearshift indicator advises you when to change gear for the best fuel economy, but its small size and obscure location at the bottom of the trip computer display means its advice will often go unheeded.
The 1.9 TDI engine is loud by modern standards, especially at idle and under full throttle. Poor low-down responses mean the motor also labours at 30mph in fourth gear, meaning that third is the (counter-instinctive) best option for driving in town. On motorways the Bluemotion is a relaxed cruiser, with 70mph requiring just 1900rpm in fifth. The tall gearing means that even shallow motorway gradients often require a downshift to fourth.
