The midsized Q6 E-Tron SUV uses a chassis that also underpins the Porsche Macan Electric. It is 4 inches longer and about 3 inches wider than the Q5, although it is the same height. There are three versions: The 322-hp Q6 E-Tron has rear-wheel drive, while both the 456-hp E-Tron Quattro and the sportier 483-hp SQ6 have all-wheel drive. EPA range estimates are between 283 and 321 miles depending on the version. The interior is dominated by an 11.9-inch display in front of the driver that curves and blends into the 14.5-inch center touchscreen. A 10.9-inch display for the front passenger is available. So far we've found our Q6 to be quick and quiet. Handling is nimble and the ride is taut, with an underlying firmness. The front seats are very comfortable and supportive. While very nice, interior fit and finish doesn't match the Mercedes-Benz EQE SUV.
