Audi A3 Sportback fuel-saving versions: is the e-tron worth it?

O b it is due to the lack of combustion noises that one is in the Audi A3 e-tron is philosophizing so quickly? For example, it is almost a shame how sparingly we flow past our regular petrol station when fuel is so cheap at the moment. Until we go back to the contents of the petrol tank, we leave a few petrol stations on the left and right, after all, our A3 Sportback with its conspicuously taped stickers managed 47 kilometers purely electrically in the test.

Audi A3 e-tron from 0 to 100 km /h in 7.6 seconds

Since the average way to work in Germany is around 20 kilometers, e-tron In other words, drivers can go there and back using electric power even if they cannot charge at work. The Audi A3 e-tron thus achieves significantly more than the almost three times as expensive Mercedes S 500 plug-in hybrid, which roamed 21 kilometers on our electric circuit.

The different driving programs also encourage philosophizing and trying out: Depending on your taste, the Audi A3 e-tron not only drives with its powerful 75 kW electric motor in the gearbox, but also cleverly combines the battery drive with the 150 hp TFSI. Together they heave the 1.6-ton truck to 100 km /h in 7.6 seconds, have a total range of 519 kilometers and convince with their polished manners, which quickly make you forget the complicated technology.

Only when in E-mode is accelerated vigorously, it takes a short moment until the gasoline engine starts and is engaged with a noticeable jolt. On the other hand, the Audi A3 e-tron drives amazingly frugally even with an empty battery: Since it often sails and recuperates on our leisurely economy lap, it manages with 5.5 l /100 km.

Audi A3 e -tron comes to 116 g CO2 /km

With brisk driving style such as motorway stretches with around 160 km /h, the hybrid module no longer has a particularly fuel-saving effect, the Audi A3 e-tron uses 9.3 l /100 here km. Nevertheless: With a typical driving profile, consisting of 70 percent electric short trips and 30 percent in hybrid mode, the average consumption is 2.2 liters of petrol and 11.6 kWh of electricity. With the German electricity mix as a basis, it comes to 116 grams of CO2 per kilometer.

The 37 grams that Audi specifies, on the other hand, show how unworldly the NEDC standard is designed, as it does not provide any electrical energyAssigns CO2 component. Which is not even true when the electricity comes entirely from nuclear power plants or renewable sources. Because even a wind turbine needs to be built and serviced, which generates CO2.

184 HP diesel impresses on the motorway

Drivers of the A3 2.0 TDI do not even think about it in the first place, since with diesel only one type of energy is available anyway. However, this is used very economically regardless of the driving profile: Although it neither recuperates nor sails, the TDI with 5.0 l /100 km is already half a liter below the Audi A3 e-tron on the savings circuit.

On the other hand, the 184 hp diesel is completely in its element on the autobahn: beyond the recommended speed, it works hardest and does not start to swallow at high speeds. With 8.2 l /100 km, it remained over a liter under the Audi A3 e-tron with a sporty driving style. The average is 6.7 l /100 km, which corresponds to emissions of 176 g /km in hard CO2 currency. Also more than the 110 grams determined in the NEDC creep mode, but not quite as far from practical use as with the e-tron.

TDI and TFSI sportier and cheaper than the e-tron

And the pure gasoline engine? Unsurprisingly, it came last with 8.0 l /100 km on average (equivalent to 186 grams of CO2 per kilometer). He is anything but a drunkard: With nine liters, the 1.8 TFSI even undercuts the Audi A3 e-tron on the autobahn, which is only surprising at first glance. On the one hand, the part-time electric vehicle weighs almost 250 kilos more, and on the other hand, it has much less opportunity to recuperate on the autobahn.

In addition, its 1.4-liter TFSI, which has a smaller displacement, has to stretch to the more powerful 1.8 -Liter to stay tuned. In general, the sporty talents of the A3 come into their own with the conventional drives: In tight bends, the TDI and TFSI appear noticeably more nimble, and the heavy battery on the e-tron rear axle has a negative impact on traction and the luggage compartment volume, which is 100 liters smaller.

Those interested in hybrid should be able to cope with that rather than the significantly higher purchase price. An A3 1.8 TFSI with dual clutch transmission costs 8,600 euros less, because neither the lower consumption nor the better standard equipment (such as adaptive suspension, LED headlights, automatic air conditioning) help the Audi A3 e-tron. Even as a Quattro with automatic, the 184 PS diesel is even cheaper than the front-wheel drive e-tron. But with that, the electrified A3 is in the best company of BMW i3, VW E-Golf and Co .: The part-time and full-time electricians impress with sophisticated technology - but without subsidies or privileges in the city they are not worthwhile in this country.
