Performance Exhausts for Hackney Carriages and Taxis

Whether you have one cab or a fleet we have a dedicated team to get you the best and more importantly you will get the same support from us to get a Vortex Exhaust performance to gain more power and torque, and more importantly save fuel and cut back black smoke. With big fuel savings to be made it makes sense to change your exhaust system. We have developed a full custom Vortex Exhaust system for Hackney carriages. Vortex Exhausts have been fitted to many other licensed taxis ranging from Peugeot diesel vehicles to Mercedes’ used for airport runs and owner was satisfied with the improvement in performance and the fuel savings.

Vortex Exhausts work well on all hackney Carriages. Most our testing was done on a TX1 Hackney carriage and a full stainless steel vortex system was developed for this. One test involved running two Hackney Carriages around the M25; one with a Vortex Exhaust and the other without. The Vortex Exhaust taxi went approximately 80 miles further on the same amount of fuel. Another test involved running a cab on five litres of diesel to see how far it would go in the traffic in London. This was done for a whole week with the standard exhaust fitted and a week with the Vortex Exhaust fitted. The Vortex Exhaust’s worst mileage was considerably better than the standard exhaust’s best mileage. Overall there was an average saving of approximately 14% in fuel. Lastly we tested the TX1 in back- to-back tests in test houses used by major vehicle manufacturers and one showed a marked improvement in fuel economy running against a modified Euro-3 test and the other showed a continual improvement in power with the Vortex Exhaust until the end of the test. The conclusion was the vehicle was improving all the time and the optimum power still had not been reached in the test.

A Peugeot Hdi was tested on a dynamometer and the power increase was 15bhp with 20Ibs additional torque. The driver reported a better than 15% improvement in fuel economy and a 10-fold drop in emissions at his MOT. Vortex Exhaust Technology Limited has a special rate for Taxi and Hackney Cab owners for a full exhaust system so please don’t hesitate to contact us.

A. This depends on where they are used. In city use in trials we got a14% reduction in diesel on daily back-to-back tests against the PCO standard exhaust on the same TX1 Fairway black cab. On a motorway test we got a gain of 80 miles extra on a full tank of diesel. Read the article on this site originally published by the taxi press.
