It all means the total price of £75,085 for our A6 S line e-tron Performance is representative of what most customers will pay. A BMW i5 Touring in M Sport trim starts at £76,455.
The Performance powertrain is the mid-range choice in the e-tron line-up above the standard car, with less power and a smaller battery, but below the all-wheel-drive e-tron quattro. You get a 94.9kWh usable battery capacity and an official WLTP range of 443 miles. So far, I have been able to match the official figure of 4.0 miles per kWh, but only on a 50mph stop-start cruise round a busy M25. In normal driving, 3.2 miles per kWh seems more realistic, but the weather has been warm since our test started, so that figure may be as good as it gets.
Performance is lively. The 362bhp output can be briefly increased to 375bhp if you use launch control, but a big family estate car needs launch control about as much as it does square wheels. It’s enough for 0-62mph in 5.4 seconds, but in the real world it means more than enough acceleration to join motorways and get swiftly out of junctions.
The 502-litre boot easily swallows three golf bags with the drivers removed, plus you’ve got a 27-litre ‘frunk’ in the nose. An early observation from the larger of our offspring (a 14-year-old who is close to six feet tall) is that under-thigh support in the rear could be better, because the seat base is low to the floor and he has to bunch his knees up. The touch-to-open electric charging flaps – one on each side of the car – are neat, but not when you’re trying to wash the car and they keep opening.
