Yes! We’ve estimated that professional taxi drivers in London can typically save around £100 a week by upgrading to the new TX. But how have we worked out this seemingly far-fetched figure that could save you up to £24,155 over five years.
Let’s say you drive 120 miles per day, five days a week. And let’s also say you’ve found an especially good deal at the pumps and you’re paying 117.7p per litre of diesel. Based on our previous model, the TX4 LE Euro 6, which delivered official fuel economy of 33 mpg (though this tended to be closer to 23mpg in real-world conditions), you can expect a weekly fuel bill of £139.
With the new TX, you’ll be able to recharge the battery overnight and leave fully charged each morning. At the national average electricity price of 12p per kWh, this would cost you about £13.95 per week. And if you’re on an economy 7 tariff, that cost could be even lower.
We’ve also assumed, as is the case for most drivers of electric vehicles, you’ll take advantage of the charging infrastructure whilst you’re out and about, topping up the battery for about 20 minutes each day. If you visit a ‘Fast’ charging point, you can expect an average cost of about 21p per kWh, and you’ll be able to replenish roughly 70% of the battery in that time. Fuel cost wise, that adds around £17 per week, taking us to a total of £37 so far. Topping up on a rapid charger takes less time but can cost a few pence more per kWh.
So, when adjusted for real-world conditions, a full charge will take you approximately 64 miles on pure electrical energy. With a full charge overnight and a partial top-up during the day, you’ll be able to cover over 100 emissions-free miles. And thanks to the flexible eCity drivetrain, the remainder can be covered using the petrol range-extender, without the need to stop again to recharge.
That means you would be able to travel up to 533 miles per week on pure electric energy, leaving only 67 miles of your 600-total to be covered by the petrol range extender. And as the range-extender isn’t powering the drivetrain, not only should you still be able to achieve the officially stated fuel consumption of 36.7 mpg, you’ll spend less than £10 per week based on the stated average costs of petrol.
So, with all the variables considered, we estimate a total weekly fuel bill of £41, compared to £139 in the previous model. And that could save you as much as £98 per week.
