When I introduced our A6, I extolled its credentials for being a great high-mileage business express and the past month has seen this well and truly put to the test.
A series of long motorway runs have reinforced my view that this A6 is a great choice if you’re covering big mileages – around 400 miles of range and, despite the S Line specification and 20-inch wheels, decent ride comfort.
At motorway speeds the cabin insulates you from wind and road noise and the A6’s large footprint imbues a real sense of stability at higher speeds.
Of course, these sort of runs don’t do a hybrid car’s economy much good, resulting in our average economy dropping to 63.3mpg – still impressive for a big ICE vehicle, but short of the claimed 100mpg-plus.
However, balancing this is the e-Hybrid’s effectiveness on shorter urban runs – a four-hour charge liberates around 55 miles of pure EV motoring, meaning I can go almost a week on my average commuting regime. To put that in to perspective, on my 17p/kWh home tariff, that’s about £4.
The aforementioned long motorway trips have also given me the chance to assess some of the options fitted to our test car. The 20-inch RS alloys are a decadent £2,300 option which you can obviously do without, but they really enhance the stance of the A6. Likewise the metallic blue paint, although this is a much more affordable £775.
The one option that is almost impossible to justify is the full-length panoramic sunroof with switchable transparency. Once you have marvelled at the ability to change the opacity from clear to opaque, and giggled at the striped opacity function, you’re left with a large glass roof which you just wish you could open. A cheaper opening glass roof would be a much better choice, although Audi does not offer this.

After a few months of driving a Q6 e-tron – the pinnacle of Audi’s current EV offering – it feels almost like a step back to take the keys to a plug-in hybrid model. From pure electric motoring we’ve now added in a thirsty and fossil-fuel munching petrol engine, somewhat at odds with the evangelical push for the adoption of pure EVs.
However, as we all know, not every driver either wants or can live with an EV, so a plug-in is the best compromise in the short term (until the Government starts increasing the Benefit-in-Kind (BiK) bandings ever further upwards from 2028).
So what we have here is almost the quintessential high-mileage company car – able to muster around a 400-mile range of combined petrol and electric power, good levels of comfort and technology, loads of cabin room, affordable BiK bills and strong residuals.
Recently revised, the A6 is a stalwart of the Audi line-up, occupying what is now a shrinking executive sector as SUVs in all shapes and sizes take over. But is it still a tempting alternative for a company executive?
Absolutely… shorn of the excessive weight of a pure EV’s battery pack, the A6 combines mile-crushing comfort and pace with a surprising level of agility on cross-country roads. It’s a car you can cover big distances in five-up with a bootful of stuff. And with the petrol tank brimmed you have around 360 miles of range, while the battery pack offers a claimed 60 miles fully charged.
Our test car is in the default S line specification, adding in all of the sporty accoutrements you expect – the bigger wheels, bulkier body kit and lowered ride height imbue the A6 with a real sense of purpose.
We’ve added to that purpose with the addition of a gorgeous set of grey 20-inch RS alloy wheels (a hefty £2,300) to offset the £775 metallic blue paintwork. Other options include the panoramic full-length sunroof with switchable transparency (£2,400) and an uprated stereo with headrest speakers (£150). All of which adds £5,625 to the £70,155 list price.
As the A6 has only just arrived on fleet it’s too early to calculate running costs, but we’re already impressed with the pure EV range and comfort. We look forward to putting many more miles under the wheels.
