The fuel-digital-wallets are a digital-wallet option for petrol and diesel vehicles, allowing them to be used online without having to take their vehicles to the petrol station.

The first car equipped with the fuel digital wallet was unveiled by Audi last month, and is being sold at an introductory price of €1 and €1.6 million.

The vehicle, a 2016 Audi A6, is now available for sale in the UK.

The fuel-dynamic-wallet-compatible vehicle is priced at €1 million, while the Audi A8, A6 and A8 Plus are all priced at £1 million.

In a press release, Audi said the vehicle would be available for a “short period of time” for a price of £1.5 million in 2018.

The company said the car is compatible with petrol and gas vehicles and the use of digital wallets is restricted to the vehicle, and the driver’s digital wallet cannot be used in the vehicle itself.

Audi said it expects the vehicle to be fully operational by 2021.

“The fuel digital wallets will be available to the public in 2019, and will include the option to connect to other online stores with their own digital wallets,” it said.

A spokesman for Audi UK said the company was also considering adding fuel-less features to the vehicles.

“We believe it is important to be transparent about how our customers choose to drive, and to offer the option of using digital wallets in the fuel economy of the vehicle,” the spokesman said.

“For example, we are looking at using digital-card payment options, such as a magnetic stripe, which would be the first step towards a fuel-free driving experience for all drivers.”

Audis spokesperson for fuel-economy, Brian Murphy, said: “The fuel dynamic wallet is available in the US for a limited time only and will be offered in Europe for the full term of the licence.”

This includes Europe, North America, Asia and Australia.
