Don't mix dry and wet curb weight, must figure about 150-175 lbs for fuel, oil, coolant
The quoted 3366 lbs. is DRY weight. Expect another 145 lbs. once you include gas (18.5 gals?) + oil + coolant... I'm guessing 3511 lbs. "curb"
The quoted 3366 by Chevy is dry weight. The Evora and Cayman are quoted with fluids. Fluids typically weigh about 150-200 pounds or so.
I didn't notice the dry/curb distinction (that's what I get for posting right before going to sleep).
Running the numbers compared to some similar cars (with the links to where I found them), assuming the C8 is 3511lb, the power to weight looks like:
C8 Corvette (at 495hp/3511lb): 7.09 lb/hp
: 7.94 lb/hp
(PDK): 8.7 lb/hp
(using DIN weight): 4.91 lb/hp
(2nd gen, using total system power): 6.77 lb/hp
(3298lb base, assuming that quoted is manual): 7.17 lb/hp
: 10.14 lb/hp
: 5.74 lb/hp
: 4.91 lb/hp
(note: I tried for a while to get the above formatted in a table, but it doesn't seem to work following the BBCode guidelines)
BMW and esp. Porsche have a VERY different model where they have been successful in selling their brand and running higher margins. Porsche's margins are the best in the world, but their volume is relatively tiny. And they leverage VW's corporate SG&A. BMW is more of a full line supplier which means their margins are lower than Porsche, but better than GM.
The above reasons are why I've said before and I will say again that Tesla will get eaten. Musk's vision is/was great. His approach of hitting the high-end first, building up capability, then working down the lower margin and volume was the right call. However, VW, Merc, GM and others are already electrifying. Why buy a Tesla when you can get a cheaper one from GM? Why buy a Tesla when you can get a newer nicer EV from VW or Merc? Once those guys are on-board, Tesla's stock price will return to earth, and they will get bought by one of the above or another. Expect this to happen in the next 3-4 years.
For Lotus, they don't have the scale or purchasing power. The not only spend more per car, but they have to charge more margin to make the corporate numbers work, which negatively affects sales. Vicious cycle. They are a niche car that many people don't know about. While on the surface the Evija Electric looks stupid(and is), it gives a big boost to the name, and now with enough money behind them they can build out the portfolio and be what they and everyone else wants to be, a Porsche alternative. Aspirational brand that charges above-market prices for niche vehicles but in decent numbers to support a proper dealer network, service etc.
I'm still very amused that just a few years ago, Porsche was basically a hedge fund that built cars as a hobby
As a kind-of-disappointed 6-year Tesla owner, I'd argue that Tesla has their supercharger network and (shrinking) vehicle assortment as competitive advantages. If you want an EV from GM right now, it's going to be the crossover-height, FWD Bolt (e.g. "any color you want, as long as it's black"). At least Tesla will sell you a sedan. While the situation is changing, VW and MB still don't sell 200-mile-range EVs - MB has the B-class EV and VW has the e-Golf, but both have ~100-mile ranges.
That said, I personally think their build quality is only on par with 90s GM
(e.g. pretty bad). What I feel really hurts is the experience with service. They have basically lost us as customers after our poor ownership experience (I personally like the description of the service experience as a combination of denial and condescension).
I feel the need to add that at the time of this post, I have no direct financial interest in Tesla (other than being a current owner and hoping they don't go belly-up before our warranty expires). I know that I'll be accused of being in bed with big oil and a short selling spawn of Satan otherwise.
