One of the few unknowns when I was handed the keys to our Audi A6 long-termer was how well its plug-in hybrid technology would fit into my lifestyle: the answer to this has been ‘very well’.

I currently work from home instead of doing a 75-mile round trip to the office each day. This has meant the A6’s official electric-only range of 34 miles has allowed me to do perhaps 95% of my journeys without burning a drop of petrol.

I’m also fortunate enough to have a 7kW Pod Point charger at home, which – combined with the A6’s 7kW on-board charger – can charge the 14.1kWh battery from empty to full in around two hours.

The PHEV powertrain has also changed my shopping habits. I worked part-time at Tesco when I was in sixth form and have remained loyal since.

It turns out, however, my loyalty can be bought and all it has taken is enough free electricity to drive 12 miles. That’s how much charge I can put into the A6 when I shop at my local Sainsbury’s. As, ironically, Tesco says, every little helps.

Audi A6 TFSIe plug-in hybrid joins our fleet

A new long-term test car day is always an exciting event and my most recent changeover was a more anticipated moment than many.

I’ve switched from Audi’s impressive A4 into its bigger executive saloon sibling, the A6, in S Line trim. The change has also seen me switch from a diesel powertrain to the TFSI e plug-in hybrid.

Combining a 2.0-litre petrol engine and a 105kW electric motor to produce 299PS, it has an official combined fuel economy of 188.3mpg with CO2 emissions of 36g/km.

This, together with an electric-only range of 34 miles from its 10.1kWh battery, puts the A6 in the 10% benefit-in-kind (BIK) tax band for 2020/21.

Its P11D price of £56,945 means a 40% taxpayer will pay monthly BIK of £190. This will increase to £209 in the 2021/22 tax year when the BIK band rises to 11%, but it still remains an awful lot of car for the money.

It’s also very well equipped in S Line trim. Standard equipment across the A6 range includes Audi’s MMI two-touchscreen infotainment system – the upper one measuring 10.1 inches – Audi’s Virtual Cockpit TFT digital instrument cluster, and integration of Amazon’s cloud-based Alexa voice control.

S Line also includes Matrix LED headlights, 19-inch wheels, sports suspension and sports seats.

On top of this, our test car features silver metallic paint (£685), City Assist Pack (£1,375), Comfort and Sound pack (£2,295) and electric heated and folded door mirrors (£150).

City Assist includes technologies such as blind spot assist, pre-sense in the event of a rear-end collision and cross-traffic assist, while Comfort and Sound includes systems such as 360-degree cameras, park assistant and a Bang & Olufsen sound system.

The addition of these packs may seem slightly extravagant, but they do add a lot of equipment for the cost and should enhance the ownership experience.

Early signs are very promising. Technically and aesthetically the A6 is an impressive package, and my time behind the wheel so far has further reinforced this: it oozes class and quality.

Hopefully, I’ll continue to enjoy it as much over the next six months as I am at the beginning.
