The new model is available from £59,900, including the government's £3500 plug-in car grant, representing a saving of £7445 over the E-tron 55. It will be available in four trim levels, with prices rising to £72,700 for the highly specified Launch Edition, which is marked out by black trim elements and bespoke 21in alloy wheels from Audi Sport.
Available to order in the UK now, the new model weighs roughly 120kg less than the 2565kg E-tron 55, primarily as a result of its smaller battery pack.
The E-tron 50's 71kWh pack – likely to be the lowest-capacity pack Audi will offer in the E-tron – enables it to achieve a range of up to 190 miles on the WLTP test cycle. That's 51 miles fewer than the 95kWh E-tron 55.
By comparison, the E-tron’s main rival, the Mercedes-Benz EQC, has a WLTP-certified range of 259 miles in its standard 400 form. A future lower-spec variant could be expected to offer less than 200 miles.
While the E-tron 55 is compatible with 150kW chargers, the E-tron 50 can accept only up to 120kW. It can still, however, be charged to 80% in approximately half an hour at a rapid-charging station.
The E-tron 50 is also less potent than the E-tron 55. It employs the same twin-motor set-up, but maximum power is down from 402bhp to 308bhp and maximum torque is down from 490lb ft to 398lb ft.
It has a 0-62mph time of 7.0sec and an electronically limited top speed of 118mph.
