Costs & verdict
Everyday costs, plus how reliable and safe it is
The A8 is competitively priced next to the BMW 7 Series and even undercuts the Mercedes S-Class a little. CO2 emissions for the A8’s regular petrol and diesel engines are higher than those of the 7 Series, but beat the S-Class, while the plug-in hybrid 60 TFSIe, with its near 30 mile all-electric range and CO2 rating of just 60g/km, makes company car drivers liable for (benefit-in-kind) tax payments of just 14%. We suspect this will make it the go-to choice for many.
Bear in mind, though, that those who mainly make long motorway journeys won’t feel the 60 TFSIe’s fuel-saving benefits quite so keenly – a plug-in hybrid’s electric motor really comes into its own at lower, urban speeds.
As for PCP finance, the S-Class historically undercuts the A8 thanks to the substantial deposit contributions that Mercedes tends to offer. Resale values of big limos like these are notoriously poor; they can lose up to half of their value from new – sometimes more in the case of top-end models – in the first year alone.
Standard equipment is very generous, though. Even entry-level cars have 18in alloy wheels, leather seats (heated in the front), a powered bootlid, adaptive cruise control, dual-zone climate control and even electric sunblinds for the rear windows.
All A8s come with a fair amount of safety kit as standard, including automatic emergency braking, traffic sign recognition and lane-keeping assistance. Unfortunately, the A8 hasn't been crash tested by Euro NCAP, so we can't tell you how well it's likely to protect you if an accident proves unavoidable.
