Audi A7 hybrid review

Audi is on a plug-in hybrid charge at the moment, with the Q5 and Q7 SUVs and A8 limousine all adopting petrol-electric power. Then there's this A7 four-door coupe, as well as the A6 four-door saloon sister and five-door Avant estate models.

As with the Q5, two variations of the Audi plug-in hybrid drivetrain are being offered in the A7: the 55 TFSI e, with 362bhp, and the 50 TFSI e, with 295bhp. In both cases, the same electric motor and 14.1kWh battery feature – only the power output of the four-cylinder turbocharged petrol engine changes.

Overall, the A7 TFSI e is a mixed bag – appealing, yes, but not without compromise. As many would expect of a large executive Audi, build quality is excellent, styling is classy, performance is plentiful and practicality is strong. Not to mention the impressive safety credentials and potentially low running costs. Still, it’s hard not to draw comparisons with the petrol and diesel A7 models (or even traditionally fuelled rivals from the likes of BMW and Mercedes), which regularly trump the plug-in A7.

For example, when running solely on battery power, the efficiency for such a large car is great and the ride nice and relaxed – but this only lasts for a while. Soon, the battery runs out and the petrol engine has to cut in. In the process, it reminds drivers that they don’t have a velvety smooth six-cylinder engine firing away under the bonnet.

Instead, they have fewer cylinders and this much is obvious when accelerating hard. This is, perhaps, the key takeaway from a hybrid A7; if maximising the potential of the battery and electric motor is possible, then the A7 TFSI e makes a strong case for itself. If not, it could be better to look elsewhere to avoid the compromises in terms of practicality and performance that the plug-in A7 models demand.

That said, for company-car drivers the low tax rate might make the A7 plug-in a winner regardless. Thanks to low CO2 emissions, the A7 TFSI e will have comparable monthly company-car tax bills to a mid-range diesel Audi A3.

Also, despite being a sleek four-door coupe, the A7 scores quite highly for interior and boot space compared to saloon or estate alternatives. The upshot of this is those looking for a large family car could realistically consider an A7. That is, unless they have a Saint Bernard or two to fit in the (rakish) boot.

For reference, the A7 hybrid’s boot is fractionally smaller than that of a Volkswagen Golf – and even more so than petrol or diesel A7s. Granted, the Golf’s boot is hardly tiny, but that car is considerably smaller and more affordable than the big Audi.

Despite the TFSI e not being the most practical or most potent model in the A7 line-up, there’s still a lot to like about the big German hatchback – all of which is discussed in greater detail in the rest of our in-depth review...
