Costs & verdict
Everyday costs, plus how reliable and safe it is
Although the costs vary depending on which engine you go for, generally speaking the A7 carries a higher list price than the equivalent BMW 6 Series Gran Turismo, but undercuts the Mercedes-Benz CLS. The same order is true if you are looking to buy on a PCP finance deal, but the A7 tends to be the priciest of the three cars to lease.
The 45 TFSI petrol engine brings the lowest rate of company car tax in the range, and it will still do around 30-35mpg in the real world, which we think makes it the best all-round engine. However, if you'll be pounding the motorways often, the vastly superior fuel consumption of the diesels could serve you better.
