Grune “deep stacker”: economy cars don’t deliver what they promise

Grune 'deep stacker': economy cars don't deliver what they promise

London, 13. August 2008 – no surprise, but always annoying: tests conducted by the british tv station channel 4 have shown that buyers of "green" car models cannot rely on the manufacturers’ fuel consumption figures. In the program "4car," the editors sent eight fuel-efficient models from various manufacturers on a test track that was modeled as closely as possible on real traffic. The testers chose the popular golf bluemotion, toyota aygo, fiat 500 1.2, skoda fabia greenline, bmw 118d, honda civic hybrid, mini cooper diesel and ford focus econetic. Apart from the toyota prius, this represents a fairly complete selection of affordable economy models, especially as the toyota aygo is also offered by citroen and peugeot in practically identical form.

Consumption target clearly missed
unsurprisingly, none of the vehicles came close to the standard values specified by the manufacturer. In practice, the additional consumption was between 0.4 and 1.0 liters; under german traffic conditions, it could have been even worse. This is because the british devised a practical but still comparatively tame driving cycle in which there was practically no traffic – otherwise a fair comparison would hardly have been possible. The "city drive" lasted 11.3 minutes, with an average speed of around 27 km. In addition, there were ten turning events with 16 km. In addition, the vehicle was stationary for 180 seconds, i.E. About a quarter of the urban driving time.

Comparison cycle on real roads
the entire test drives consisted of 10 percent "city," 15 percent "suburban," and 25 percent each of highway, "brisk," and "leisurely" country road driving. Vehicles still benefit from the fact that in the uk, freeway speeds do not exceed 112 km. The environmental conditions were also favorable: all cars started at 10 °c, which is typical for the united kingdom, and drove the route with the electrical consumers switched off.
