The recent long-distance test of the rear-wheel-drive (RWD) version of the Kia EV6 (with a 77.4 kWh battery) brings an interesting result.
According to Bjørn Nyland's 1,000 km (621 miles) challenge, the car completed the distance, at an average temperature of 3°C, in 10 hours and 10 minutes (after some time deductions).
During the challenge, the car was charged a total of five times along the way. The average speed (including charging stops) was 98.4 km/h (61 mph).
It's a very good result, however slightly slower (by 15 minutes) than the previously tested Kia EV6 AWD.
The difference is relatively small and might be associated with many factors, as the challenge test is quite complex. However, it is a bit surprising. We would expect - especially after the range test - that the RWD version would be more efficient and a bit faster than the AWD version. After all, it's lighter.
Maybe the answer is the temperature. It was colder in the case of the RWD test (by a few degrees) and the E-GMP cars note lower fast-charging power when the battery is cold (the battery pre-heating feature has not been implemented yet).
Bjørn Nyland notes that the E-GMP platform is designed to minimize the eventual losses of efficiency and range related to the addition of the front-drive unit for all-wheel drive.
