The C&D article has some pretty funny numbers for the Bolt EV that don't match other reviews (and don't really match other numbers that C&D provided). Now, the Kona Electric could have over performed relative to its published performance numbers, which miraculously resulted in slightly better numbers than the Bolt EV's numbers that exactly matched published performance numbers. And despite C&D's acceleration numbers for the Bolt EV aligning with Motor Trend's (within .1 to .2 seconds) until 0-90 mph, where the Bolt EV in C&D's hands inexplicably lost .6 seconds compared to Motor Trend's testing.
The efficiency numbers also require explanation if the Kona Electric was, in fact, driven under similar circumstances to the Bolt EV. The Bolt EV repeatedly exceeds EPA ratings, so why was their 600-mile trip so much less efficient than EPA ratings while the Kona Electric's was better?
When I look at the results of the datasheet, though, it makes sense because without the stark difference in efficiency, the only ways the Kona Electric was scored higher were completely subjective. It's almost as though, if the Kona Electric is the decisive new "Bolt EV killer," it can't be just a little bit better. It has to be strictly better.
Now, it's entirely possible that the Kona Electric is as close to the Bolt EV in performance and efficiency as C&D claims, so I'll reserve judgment on the Kona Electric until I (or a trusted source) have a chance to test it. However, I know several of C&D's numbers for the Bolt EV are inaccurate (or at least lack context), so this article actually leaves me with less information about the Kona Electric relative to the Bolt EV than I went in with.
