How much does the Audi A8 cost to run?

The 3.0L diesel is the most economical Audi A8 to run, taking into account insurance, tax and fuel efficiency.

The Audi A8 3.0L diesel costs £160.00 a year to tax, as it sits in tax band F.

It does not far off 50 MPG on average, which means it will cost £12.00* in diesel every 100 miles driven.

In terms of fuel efficiency, it sits between the BMW 5 Series 2.0L diesel and the more thirsty BMW 5 Series 3.0L diesel.

The lower the insurance group, the cheaper a car should be to insure. This model is rated insurance group 46, which is lower than the BMW 7 Series 3.0L diesel, but higher than the Jaguar XF 3.0L diesel. (If insurance cost is important to you then the Volvo V70 has the lowest insurance group.)

Audi A8: How big is the boot?

The Audi A8 has a below average boot space (500 litres of luggage with the seats up).

This would allow one pushchair and 3 large bags. Alternatively you could load up with 4 large bags or 4 cabin bags instead.

Worth knowing, the Volvo V70 estate is the best in class, allowing for one pushchair and 5 large bags with its 815 litres.

Is the Audi A8 easy to park?

Given a typical supermarket space, the A8 is hard to park. (If you want the detail it will fill 81% of the bay). This is the widest car in the Large Executive class, and you may need to breathe in a bit when getting in and out.

This car is actually 387mm longer than the average street space, so parallel parking will never be easy.

Which Audi A8 has the best performance?

The fastest Audi A8 from 0-60, is the 4.1L diesel (if you’re a petrol head, it has 850 lbs/ft torque and 385 bhp). It hits 60 mph in 4.7 seconds.

The closest rival in its class is the BMW 5 Series 4.4L petrol, which will beat your Audi A8 to 60 by 0.1 seconds. That’s a big gap in Formula 1, but not something you would notice in your commute to work.

What size caravan or trailer, can the Audi A8 tow?

If you are towing you want good torque to pull away easily despite the extra weight, and the car needs to be at least 15% heavier than the caravan to keep you stable at speed.

The model that can tow the biggest caravan or heaviest trailer is the Audi A8 4.1L diesel which has 850 lbs/ft torque. It should be able to tow a braked caravan or trailer that weighs up to 2300kg comfortably.

You must check your car handbook – maximum towing weights vary considerably with different engine and gearbox combinations.
