I doubt very much that either Chevy or Nissan are going to create an EV to lust over.
They can't even create an ICE to lust over. Well... maybe with the exception of the Corvette. Even when GM does produce something really nice - like the Buick Avista - you get the sense that it can't go to production without being ground through the bland-o-tron.

It really depends on your idea of bland. CTS-V, ATS-V, Camaro, etc, you can spot a GM at a distance.
The Corvette is not an exception. It doesn't even have competitors. Chevy builds them for Chevy folk. Euro guys need not apply. It's not priced high enough, the badges aren't large enough, it lacks a "real" grill, it's too fast, handles too well, sounds too good, and gets too good of fuel economy, Sadly, they are sold with automatics available in most models, which blows. Yes, it's perhaps the world's finest automatic today, but still.
My ZR1 is "bland" smooth styling. It doesn't "claim" to exceed 200mph, it actually does. It's doesn't claim to run 10.9, it actually runs quicker. It has real brakes (big ass carbon ceramic Brembos), powerful electronic warfare tricks for wussies, and handles like a 2000lb car.
Oh, and the Nissan GT-R "Godzilla" is indeed a "Tesla Killer", regardless if you like the look or not.
PS - Elon said the other night the Model S is the "fastest four door". Exactly what were it's Nurburgring times, and top speed? I know my CTS-V 4-door had a stupid 175mph speed limiter. Others ran the ring at 7:xx in the 2009 CTS-V. Not sure any Tesla can match that or the $60k price tag.
