You've no doubt seen the advert above at some point and wondered what on earth it's all about.
It's okay - we thought the same thing upon first viewing. The message in the video is quite subtle, but will become quite an important part of Audi's range next year when the plug-in hybrid A3 e-tron hits the streets.
But what makes the A3 e-tron special? Earlier this year, we flew to Berlin to get a much closer look at the firm's first production plug-in vehicle.
In the past, Audi - and the rest of the Volkswagen Group, for that matter - has sung a distinctly diesely tune. European regulations play heavily on carbon dioxide emissions, and this is something diesels are particularly good at avoiding. Diesel has a higher energy content than petrol so actually produces more CO2, all other things being equal - but the frugality of diesel engines means the overall CO2 output is often lower than that of an equivalent petrol. Less fuel used means less CO2 produced.
Because of all those tax breaks, diesel has dominated in Europe and VW has put a great deal of money and resources into its diesel programs - from ultra-frugal small cars to all-conquering Audi Le Mans vehicles.
There's a problem though - diesel engines are getting more and more expensive to make (and therefore buy) as stricter emissions regulations control the particulate matter they can produce. There are also rumors the fuel will become scarce over the next few decades. Essentially, automakers are looking for alternatives.
Petrol plug-in power
One alternative is hybridisation - pairing combustion engines with electric power.
Toyota's Prius does just that: You get an engine and an electric motor, each providing propulsion but requiring less power (and less fuel) to do so.
The electric motor's assistance is limited though as the batteries aren't very big. To eke out more electric range you need bigger batteries, and to fill these efficiently you need a plug - hence the plug-in Prius we tested last year.
Audi's A3 e-tron is essentially the German brand's take on the plug-in Prius - only a chunk more powerful and several orders of magnitude more desirable.
Its engine is actually smaller than the Prius's 1.8-litre unit, at 1.4-litres - but uses a turbocharger to boost power. Together with an electric motor, it produces 204 horsepower and a punchy 258 pounds-feet of torque, enabling a hot hatchback-like 7.6-second 0-62 mph sprint.
Top speed is 138 mph, while the motor alone is strong enough to enable an 80 mph top speed under electric power. Power is sent through a six-speed dual-clutch transmission.
The important bit though is the car's electric range - just over 30 miles on a full charge. While this would be atrocious in a regular electric car, it doesn't really matter in a plug-in hybrid - just like the Prius and the Chevrolet Volt/Vauxhall Ampera twins, it'll just keep on driving once the electrons have given up.
Overall economy is a spectacular 188 mpg. Take this with a Dead Sea's worth of salt, though - as ever, your combined economy depends entirely on what proportions of petrol and electric you use. Don't expect mpg in the hundreds as you pound up and down the motorway...
Vorsprung durch high-Technik
So it's quick and it's frugal. It's also (like the robot) suitably high tech.
Like an increasing number of plug-in hybrid vehicles, the A3 e-tron features a hold mode. This means if you live in the sticks but end your commute in a city, you can hold the electric mode for when it's most useful - crawling in traffic.
If you've managed to waste that electric range, you can also set the car into a "charge" mode, where some of the engine power is used to put charge back into the batteries.
A host of minor engine detail changes over the regular 1.4 TSI unit ensure that it's more than ready to deal with unusual usage patterns too - hybrid engines spend a lot of time switching off and on, lying idle, or not being used at all.
Then there's Audi's clever home charger, which it'll install for e-tron buyers for an as-yet unannounced cost. Because batteries work their best at a certain temperature, the charging wall box will actually hold its final ten minutes or so of charging until the morning. Charging generates heat in the battery, so by feeding in that final charge before you unplug the car and head to work, the batteries are raised to their optimum operating temperature before you drive off - for better battery life and improved range.
Should I buy one?
You'll have to wait a while for the e-tron - as Audi's advert suggests, until Autumn 2014.
When it does arrive, it's also likely to cost over 30,000, a good chunk more than an Audi A3 Sportback 2.0 TDI and many thousands more than the most frugal 1.6 TDIs.
Whether you think it's worth it for the e-tron's unique qualities - the performance, the reduced noise, the electric running and the joy of never picking up a greasy diesel pump again - is up to you. For some, that Audi badge is all you need to make the car worth buying in the first place.
And if you'd still prefer the diesel? Well, at least you now know what that robot advert is all about...
