First - this article is entirely about engine vs motor efficiency (ie what percentage of energy used is actually converted to forward momentum). Second - your own source concluded that the studied BEV has lower lifetime emissions (including manufacturing) than the studied ICE car, albeit with a high uncertainty - they estimate that the the BEV has 27-54 tonnes of emmissions vs 58 tonnes for the ICE, or 47-93% of the ICE's lifetime emmissions.
