The unenviable task of taking the survey across five of the UK’s major cities fell to Citroen, who found London to be the worst place for being stationary in traffic after 36 minutes were spent at a standstill in an hour.
This compares to just 19 minutes in 2006 for the capital, and was the most amount of time spent at a standstill compared to Norwich (20m 29s), Manchester (28m 39s), Birmingham (22m 03s) and Cardiff (20m 38s).
Marc Raven, Citroën’s Communications Director, commented; “Despite a general downward trend in traffic during the economic slowdown, many urban commuters are experiencing similar, if not worse stop-start journeys to work as they were five years ago.”
The study did have a practical use, however. Citroen was demonstrating the benefits of Stop & Start technology, a growing feature on new cars on the market today.
The technology turns off the engine when the car is stationary and instantly restarts it when the brake is released. In some cars, an ‘e-booster’ is used to increase the speed of the car restarting.
Designed to reduce the amount of fuel a car uses, the technology is one of the ways car makers have been able to reduce CO2 emissions and fuel consumption across their line ups in recent years.
Peugeot and Citroen recently launched their second generation Stop & Start system and plans to include it in over one million diesel cars by 2013.
The technology can help cars such as the Citroen C3 and DS3 deliver CO2 emissions below 100g/km – enough to qualify for the lowest band of UK road tax. It also offers fuel economy of over 70mpg on the C3.
The new Citroen C4 will also include the Stop & Start technology including the e-booster, which will come under the e-HDi name.
