Audi has updated the plug-in hybrid variants of the Q5, A6, and A7 Sportback TFSIe models with a bigger lithium-ion battery pack for a longer EV driving range.

The new battery pack measures 14.4 kWh in net capacity (17.9 kWh gross), instead of the previous gross capacity of 14.1 kWh. The result is a longer EV range that’s up to 91 km (56 miles) on the NEDC cycle, and up to 73 km (45 miles) according to the WLTP standard.

The new bigger battery, which hasn’t changed in dimensions, is accompanied by a maximum charging capacity of 7.4 kW, which means that the plug-in hybrid Audi models can be fully charged in around two and half hours when plugged in.

Together with the new battery upgrade, Audi is launching the A6 Avant  50 TFSIe Quattro in Europe, as the entry-level variant of the model. The electrified powertrain combines a 2.0-liter TFSI with a 140 HP electric motor for a combined output of  294 HP (299 PS) and 331 lb-ft (450 Nm) of torque.

All five upgraded plug-in hybrid Audi models also get the new ‘Charge’ driving mode, in addition to the existing ‘EV’, ‘Auto’, and ‘Hold’ modes. The new driving mode allows the battery to be charged by the combustion engine while driving, for example before arriving into specified environmental zones.

The plug-in hybrid Audi Q5, A6 Sedan, and A7 Sportback models are still available in two power outputs: the 50 TFSIe with 294 HP (299 PS), and the more powerful 55 TFSIe with a system output of 362 HP (367 PS). Both variants use the 2.0-liter TFSI four-cylinder petrol engine paired to an electric motor and a seven-speed dual-clutch transmission.

Audi’s range of plug-in hybrid models now includes the A3 Sportback, the Q3 and Q3 Sportback, the Q5 and Q5 Sportback, A6 Sedan and Avant, A7 Sportback, Q7, Q8, and the flagship A8.
