While much talk around electric cars is focused on small, affordable, runabouts, there's another category of car that can benefit just as much from electrification (or even a degree of electrification). That's the luxury limousine, where smoothness and near-silence (for passengers) and low running costs (drivers) are vital.

You can already get plug-in hybrid versions of the current BMW 7 Series and Mercedes S-Class, and now Audi has joined the party with the A8 TFSI e – the flagship of its line-up of plug-in hybrid vehicles that also includes the Q5 and Q7 SUVs, the A7 four-door coupe and the A6 saloon. The car's '60 TFSI e' powertrain comprises a 3.0-litre turbocharged V6 petrol engine plus a 126bhp electric motor, with a combined total power output of 443bhp. Power is sent to all four wheels through an eight-speed automatic gearbox.

Audi quotes a 0-62mph time of 4.9 seconds along with a top speed of 155mph, while official fuel economy and CO2 figures are bang on the money for this segment. Only a Sport trim level is offered, available in standard or long-wheelbase guise. When the 14.1kWh battery is fully charged (which takes about two-and-a-half hours from a 7kW wallbox), the A8 TFSI e will go for just under 30 miles without the engine switching on, at speeds up to 111mph. That means faster electric running than either the Mercedes S 560 e or BMW 745e.

On the move, the A8 is a very smooth drive, with the transition from electric to petrol power being almost imperceptible, save for some occasional driveline shunt. With the help of a dashboard indicator, you can be gentle enough with the accelerator to avoid waking the petrol engine, too. An EV mode instructs the car to prioritise battery power, but in general it's better to leave the car in Hybrid mode and let it work out the best combination of electric and petrol power to keep moving as efficiently as possible.

To help it do this, sat-nav, live traffic and topography data are all called on. You can also prioritise the petrol engine if you want to save battery power for urban running later in your journey. Elsewhere, the A8 is as impressive a large luxury car as it has always been, remaining uncannily quiet inside regardless of which power source you're using, how fast you're travelling or what type of road you're passing over. In terms of ride quality, it falls just short of the S-Class's benchmark and is broadly on par with the 7 Series.

Interior materials are pleasingly luxurious throughout, although we're not totally convinced by the 'haptic' feedback employed by the large twin infotainment screens; it takes a bit of getting used to and means you have to give the screen a proper press rather than just a tap for it to do anything. In practice, this is more distracting than a regular touchscreen when you're on the move.

These niggles aside, the A8 hybrid seems entirely fit for purpose as a hugely comfortable, classy and (relatively) environmentally friendly way of transporting VIPs and dignitaries around. For a more detailed look at the Audi A8 hybrid, read on for the rest of our in-depth review...
