Audi: Plug-in hybrids get a larger battery

[ad_1]

The sale of plug-in hybrids is currently subsidized with plenty of tax money, which is quite controversial. Because the environment usually only has a lower impact if green electricity is diligently charged and the proportion of electric routes is high. Audi is now creating slightly better conditions for the latter by increasing the size of the battery in the plug-in hybrid models in the A6, Q5 and A7. So far it was 14.1 kWh, now it is 17.9 gross, and 14.4 kWh can be used.

In the press release, Audi promises a range of up to 73 km in the WLTP consumption measurement cycle. That is not wrong, but it is worth taking a look at the small print, because this value only applies to the A7 and only in urban areas. In the combined cycle, depending on the model, the following ranges are possible in E mode:

model

Range WLTP in km

Q5

56 to 62

Q5 Sportback

56 to 62

A6

62 to 68

A6 Front

60 to 66

A7

61 to 69

This should allow distances that commuters cover on average to be covered easily. In all three models, the customer has the choice between two power levels: the slightly less powerful offers 220 kW system power, the more powerful 270 kW. In both cases, the combustion engine is a two-liter, four-cylinder petrol engine with 195 kW. The possible driving performance is pretty rapid. The A6 station wagon accelerates from standstill to 100 km / h in 6.3 or 5.7 seconds, and the top speed is 250 km / h.

The construction is always the same: the electric motor is integrated on the input side of the double clutch transmission with seven gears. An electric secondary axle, in which an electric motor only drives the rear wheels, would be more efficient and significantly more complex. Audi takes a different approach and only distributes the power to all four wheels behind the transmission output.

There is a new “Charge” mode with which the battery can be charged while driving. However, this should remain the absolute exception, because the combustion engine bills the extra work in the form of higher consumption significantly. The better way is through an electrical outlet. Audi promises a charging power of up to 7.4 kW, but without revealing any details about the charger itself. That’s why we asked the friendly press office: The charger has a two-phase design. With a wallbox, the maximum charging power can also be used at home. The option of being able to charge the battery with direct current, as Land Rover and Mercedes offer at least at an additional cost, does not exist at Audi.

Cars like the A6 have to convince fleet managers, after all, the majority of new registrations are due to commercial customers. So it makes sense for Audi to have a wide range here that is tailored to this group of buyers. That is why the A6 Avant is getting another plug-in hybrid that offers 220 kW and is available from 61,790 euros. The only astonishing thing is why Audi was so hesitant with this expansion, because the drive has been available in the sedan for some time.
