1. If operating in Pure EV mode, when the range reaches zero will TX automatically switch to a different drive mode to engage the range-extender?


When operating in Smart mode TX will automatically activate the range-extender before the range reaches zero. In Pure EV it will not, instead the vehicle will prompt the driver to change drive mode before the range reaches zero and then limit the power delivery. If these prompts are ignored the vehicle will ultimately stop. When the range reaches zero, in order to get the taxi started again the driver will need to select a different drive mode.

2. Is it possible to download or add 3rd party “apps” - such as the Zap Map charge point locator - to the touch screen console in TX?


To protect the interface we control what can be installed, as untested apps can interfere with the existing functions. At this moment in time 3rd party apps from the App Store or Google Store aren't compatible with the touch screen console. However there is ample space on the accessory bar, and complimentary on-board Wi-Fi, which allows drivers to attach a tablet and/or mobile phone which could run 3rd party apps such as Zap-Map or Android Auto.

3. What card payment readers are approved to use in TX?


We're constantly working with providers to give drive the greatest choice possible. For a list of card payment providers approved by TfL for use in the electric taxi please click below.

4. Has TX got air conditioning in the driver and passenger compartments as standard?


Yes both compartments have independent climate control with powerful, automatic digital air conditioning and heating.

5. Why is the petrol range-extender fitted with a turbo?


The turbo helps improve the efficiency and durability of the engine.

6. Is it true the petrol range-extender is governed by a sensor that if you went in to certain places in London they will be able to stop it from working until you're out of that area?


Unlike other European cities we're working with, there is currently no geo-fencing requirement in London. However if TfL were to introduce this requirement, we have a supplier in place who we'll work with to fit the necessary on-board software.

7. I sometimes hear the fan on when the engine is off or whilst on charge, is this normal?


Just as in diesel or petrol vehicles with traditional combustion engines, it's normal for the fan to run for a short while after the vehicle has shut down. Since the engine has stopped running it no longer circulates coolant to cool it down, therefore the fan kicks in to cool the necessary components - you'd definitely expect to hear in during the warmer summer months. It's also worth noting that TX will also run the fans as required while plugged in to charge, for the same reason.

8. Does the odometer on the display show a total distance travelled on electric & petrol, if so can they be shown separately?


Currently the odometer shows a combination of the distance travelled on electric and petrol. We aim to be very transparent with our new vehicle and we're continually looking for ways to share more information with drivers, which is why we're looking at how to separate this data in the future.

9. If the card payment system in the rear stays on overnight, won’t this drain the vehicle battery?


We've worked closely with all of the approved card payment providers and supplied installation instructions which allow their units to automatically turn off an hour after the vehicle has stopped. All card payment systems can also be wired so the reader in the passenger compartment always stays on. Systems such as Verifone use their own battery which does not interfere with the electrics of the cab; there have been no instances where it has been confirmed that the unit drains the vehicle battery.

10. If I left my TX unused for a week will it still start?


Yes that isn't a problem, just like any other vehicle TX relies on a 12V battery to start the system.

11. Is TX classed as a Zero Emission Capable vehicle?


TfL classify a zero emissions capable taxi as one with an official combined CO2 output of less than 50g, which can travel at least 30 miles on electric only. TX comfortably exceeds these requirements with 19g/km and 63 miles on the WTLP test cycle.

12. Are there any guides for operating TX?


There most certainly are. We understand that diving any new vehicle is exciting, but it also has the potential to be intimidating. To help improve customer confidence for those living with TX or driving during unaccompanied test drives, the TX Quick-Start Guide provides a handy point of reference on the most basic vehicle functions. These functions should always be explained to the driver before they get behind the wheel, and our free download can act as a physical reminder to provide reassurance and ensure a more enjoyable driving experience. Alternatively you can always refer to our free TX Operator App, available in Google Play and Apple App Store.

13. Does the fuel cut off switch at the boot disable the cab completely?


No the fuel cut off switch simply stops the petrol range-extender from working, you can still operate in Pure EV mode. The switch is part of TfL Conditions of Fitness but isn't really necessary on newer vehicles with more sophisticated engine safety precautions.

14. Why does TX turn off automatically if left idling for a period of time?


The TX electrical system requires various circuits to remain active while the meter is running. To preserve the charge of the 12v battery and ensure sufficient energy to restart the vehicle, power to the meter is switched off after one hour of inactivity. It is possible to extend the waiting time by another hour by cycling the ignition.

15. What type of electric vehicle is TX?


TX is a range-extended electric vehicle. This means that it is always driven electrically by a motor and powered by a battery. The electric range of 63 miles, combined with flexible plug-in charging options, gives most taxi drivers the ability to complete their day on electric power.

Because the nature of a taxi driver’s work is varied and unpredictable by its nature, TX also has a small petrol range-extender fitted. This is not connected to the wheels and cannot drive the cab as an engine, it acts as a generator to send electrical energy to the battery and ensures drivers are able to complete their fare before needing to stop to recharge. It is this technology which overcomes the range anxiety faced by many operators and gives the confidence to consider an ultra-low emissions cab.

As well as emitting none of the harmful particulates associated with a diesel engine, TX combined CO2 emissions on the official WLTP drive cycle, which includes use of the range-extender, is only 19 g/km. This compares to between 212 and 244 g/km for a diesel London Taxi (depending on model / age) and represents a huge step towards improving the air quality in our cities.

16. How do I pre-warm/pre-cool my TX using mains electricity rather than taking energy from the drive battery?


In an electric vehicle, the cabin temperature is maintained electrically using energy from the drive battery.

When charging your TX, whether overnight at home or on-street, you can set a ‘Parking Climate’ timer to prewarm or pre-cool the cabin using the mains electricity. This feature automatically activates the climate control system to restore the last set temperature and fan speed. This means energy isn’t taken from the battery to do the same job after you’ve driven away, helping to preserve your electric range…plus, you get to climb into a cab that’s just the way you like it.

17. Some TX drivers have described a feeling of ‘surging forward’ while slowing down. Does this indicate a fault with the vehicle?


This sensation is a characteristic of the way the braking system operates, it does not affect the braking performance of the taxi, or indicate a fault with the vehicle.

Antilock Braking Systems (ABS) use sensors to identify if a wheel is beginning to rotate more slowly than expected during braking, indicating a loss of grip that will lead to the wheel ‘locking up’. Hydraulic valves reduce the braking effort on the affected wheels, preventing them from skidding and allowing the driver to maintain control.

TX features regenerative braking, recovering energy that would usually be lost while slowing down to recharge the drive battery.The regeneration generates drag on the rear wheels as the vehicle gradually slows while coasting and up to around 10% of brake pedal effort.

When wheel slip is identified, the system must react by deactivating the regeneration to reduce the drag on the rear wheels. This could be the result of a heavy braking event, slippery conditions or a change of road surface (such as ironworks). Disengaging the regenerative braking has the effect of reducing the rate of deceleration; this can give the feeling of vehicle surging forward and drivers typically react to this sensation by applying the brake pedal harder. In many cases, the affected wheel has already begun to rotate normally, and the vehicle reacts to the new input by slowing more rapidly.

This sensation only occurs at low speeds and under light braking, where the vehicle is being slowed by the regeneration. In emergency braking events, most of the braking effort is already being achieved using the hydraulic wheel brakes and so the sensation of the ABS working in the conventional way is more familiar.

Working in conjunction with the ABS system, Autonomous Emergency Braking monitors the road ahead, ready to react if an imminent collision is detected. The system operates more quickly and effectively than most humans can and while antilock braking systems normally decrease stopping distances, on very slippery surfaces, such as gravel or snow, ABS may actually increase the overall braking distance, but allow the driver to maintain steering control.

The very latest safety technology, fitted as standard, is just one reason the new TX is our safest taxi ever.

18. Does the TX have a catalytic converter?


Yes it does – it’s just one of the emissions-reducing technologies utilised by our highly-efficient range-extender, which contributes to its combined CO2 emissions (on the WLTP cycle) of just 19g/km, which assumes some use of the petrol range-extender.

19. How does the air-conditioner system work in TX?


​The heating and air-conditioning system in TX is dual-zone, so as long as the system is switched on, the driver and passengers can set their own independent temperature and fan speed. The driver also has the ability to control or turn off the rear cabin from the central touchscreen.

20. Can I adjust the volume of the road traffic announcements?


Yes. All sounds can be adjusted in the settings of your TX.
Find the setting on your touch screen by clicking: Settings > Sound > System Volumes.
