MPG and Fuel Efficiency Advice
In the past, wealthy and influential people reserved luxury saloons for themselves. However, movie stars now frequently travel in vans with first-class levels of rear seat luxury, while the majority of politicians are chauffeured around in bulletproof SUVs. This indicates that large, elegant saloons are reserved for those who value luxury in a dark and understated way.
Although luxury SUVs are increasingly the preferred vehicles among purchasers in this market, these individuals will also have the Mercedes-Benz S-Class, BMW 7 Series, and Lexus LS on their shopping lists. Thus, the Range Rover, Mercedes-Benz GLS, and BMW X7 are competitors of the A8.
Although A8 running costs are not exactly the top priority given list prices that can easily reach six figures, it is comforting to know that they will be less expensive to operate than the model they replaced for businesses that use these vehicles in their fleet. Based only on the numbers, the plug-in hybrid model is the preferred option.
Audi A8 Fuel Consumption
Official calculations indicate that a near 30-mile electric-only range will help both the standard- and long-wheelbase variants achieve nearly 100 mpg. Make sure you don't use the petrol engine very much, if at all. This will result in a significantly cheaper fuel cost.
If you frequently utilise the petrol engine, don't expect to get close to the 100 mpg figure because the A8 is a huge and powerful car. Additionally, the diesel engine was a mixed bag. In the long term, we outperform Audi's estimated 39.8 mpg. However, it dropped to less than 20 mpg around town, which is not ideal.
All regular A8s have some battery help, but they won't operate entirely on batteries like the PHEV does because they are electrified (albeit only mildly hybridised). Because of this, both V6s emit relatively little CO2, making them a positive step.
Although there isn't a cheap method to operate an Audi A8, the regular 50 TDI offers 40.4 mpg combined economy and 184 g/km of carbon dioxide emissions.
Selecting the hybrid model will save you up to 148.7 mpg and 42 g/km, which is equivalent to 36 miles of EV driving; however, these savings are offset by the higher initial cost of this model.
If you choose a more basic petrol variant, the 55 TFSI produces 204g/km of CO2 and 31.0mpg.
The hybrid's £10 first-year road tax provides some relief from the high operating expenses. The Audi S8, on the other hand, will have to pay a much higher £2605.
The 50 TDI and 55 TFSI basic versions, which are part of Group 44, are the least expensive in terms of insurance. Everything costs more after that, and the best Audi A8 models fall into the highest Group 50 price range.
The fuel consumption of the Audi A8 is shown below in both MPG (Miles Per Gallon) and km/L (Kilometers Per Litre). Both of these figures show you how far that particular Audi A8 variant can travel for every gallon (4.55 litres) and every litre (1000ml) of fuel. The higher the MPG or km/L value, the more economical the car is and the cheaper it will be to run. As well as providing the combined figures, we also give you the fuel consumption you can expect from a Audi A8 in urban / city driving conditions as well as what can be expected on the open highway / motorway.

The 'real fuel consumption' shows you the amount of fuel your Audi A8 is consuming to travel a fixed distance. This is normally shown as L/100km. This figure shows you the amount of fuel consumed in litres for every 100kms travelled. This is the most commonly used figure for showing the fuel consumption of a vehicle. The formula to calculate it is:
(Litres of fuel used X 100) / Kilometers travelled = L/km.
