Converting the popular black TX4 taxi to a cleaner, Euro 6-compliant cab is now an option for many taxi drivers as news from the Energy Saving Trust endorsing the technology is released.
The news is well received by many in the industry and follows the recent Peugeot E7 taxi conversion approval.
Several large councils across England and Scotland are currently offering grants to taxi drivers wishing to upgrade the taxis they drive to cleaner levels that meet the EURO 6 standard.
Taxi drivers could switch to greener taxis for as little as Â£ 1,300 in some cities, according to the latest published research.
In addition to purchasing a new zero emission capacity taxi (ZEC), modernizing existing cabins to meet Euro 6 compliance standards is seen as a way to eliminate daily costs and make a driver’s taxi sustainable. . Using a fully approved retrofit conversion could not only save money on fees, but will also ensure that the taxi is less harmful to the environment.
Several councils in England and Scotland have given grants to taxi drivers to switch to cleaner technology.
According to Cybrand, a UK company that provides emission and exhaust control solutions for diesel engine applications, Manchester, Birmingham, Portsmouth, Bradford and Bath all offer taxi drivers the option of converting their taxis in England. In Scotland, the four big cities of Glasgow, Edinburgh, Aberdeen and Dundee also offer clean air subsidies to taxi drivers.
The conversion is currently available for Euro 5 Mercedes Vito, Peugeot E7 taxis and now the LTi TX4. The price is Â£ 5,195 + VAT, although for most cities implementing clean air zones, grants are available through local government, usually for 80% of that amount, meaning the cost typical for a taxi driver is only Â£ 1,234.
The table below shows the funding details for each city:
The accreditation required to be exempt from emission zone fees within the LEZ or CAZ is known as the Clean Vehicle Retrofit Accreditation Scheme (CVRAS) and is administered by the Energy Saving Trust.
According to sources, Britain’s largest taxi licensing authority, Transport for London (TfL), has yet to approve the refurbishment and the approval process is still ongoing. TfL has chosen to use its own testing regime rather than that of the recognized Energy Savings Trust standard used in the rest of the UK.
On a standard taxi conforming to the Euro 5 standard, the exhaust gases from the turbocharger pass directly through the combined catalytic converter and diesel particulate filter and from there through the muffler to the tailpipe.
On a modernized cab to Euro 6 standard, a new Selective Catalytic Reduction (SCR) system is installed in the exhaust system further downstream. This incorporates a thermoelectric element that helps bring the exhaust to an ideal temperature to encourage efficient catalytic conversion. With the introduction of AdBlue, which is a diesel exhaust fluid, the SCR system reduces NOx to levels that exceed Euro 6 requirements.
SCR is beneficial because it reduces NOx by up to 90% and is one of the most cost effective and fuel efficient technologies available.
The upgrade system also comes with a full 2 ââyear warranty and local installation options are being deployed around the clock.
