First things first: I’d like to show you all the new E-Ray’s power curve, as it includes that of the 6.2-liter naturally aspirated LT2 V8 and that of the electric motor, overlapped. You’ll see peak power for the gas engine is 495 ponies, and that of the electric motor is 160, though the shapes of the curves are quite different. It’s worth noting that the x-axis, speed, is probably not what you think it is. The only thing linking the electric motor’s RPM to the gas engine’s RPM is vehicle speed, so X-axis is likely related to that. I assume it’s just peak power as a function of vehicle speed, with the jogs in the plot being gear changes? I’ve asked GM for clarification. Maybe one of you in the comments knows for sure.
The above video has me going through the features.
Anyway, let’s have a look at some gorgeous imagery.
The 6.2-Liter V8
Chevy’s got a rendering and a “technical drawing showing the LT2 in all of its glory. Check them out:
The photos come with a description mentioning 210mm diameter equal-length intake runners, and a dry sump oil scavenging system for track use:
Eight-Speed Automatic Transmission
Check out the above beautiful graphics showing the eight-speed dual-clutch transmission. Chevy describes the images, writing: And to give you an idea of the gear ratios, Chevy shows roughly what percentage of the vehicle’s top speed each gear will get you to before hitting the engine’s max RPM:
The Battery Pack
Check out the 1.9 kWh battery packaged along the Corvette’s spine. A few years ago, I helped tear down a C8 Corvette, and in so doing I was able to have a look at that packaging location/void right there along the vehicle’s longitudinal axis; check it out:
From Chevy:
Chevy’s website shows the battery’s power as a function of relative vehicle speed — both output to the motor and input from the motor during deceleration/regenerative braking.
Electric Motor (Drive Unit)
At the front axle sits the electric motor and gear reduction. Chevy’s description notes that the motor’s max torque is 125 lb-ft.
The All-Wheel Drive System
The mid-mounted V8 powers the rear wheels, while the electric motor independently powers the fronts through the aforementioned gear reduction. Chevy describes the all-wheel drive system, writing:
The site even shows the graphic above, which turns blue when accelerating (the motor is adding power) and green when decelerating (the motor is generating power and sending it to the battery pack).

Far too much added complexity to justify the benefit, in my opinion. The problem is that people want to think that “hybrid” means a significantly greener or more economical vehicle, because that’s how it has been marketed. I’ve been on the engineering team for a few mild hybrids, and you can make CO2 savings that are significant for a fleet of vehicles with technology that produces a barely noticeable effect on a single vehicle. Especially as almost no one bothers to drive in a way to minimise CO2. Even on a road course (which this is not really intended for), your long straightaways are going to be broken up by braking zones that will recharge the battery. This car isn’t for me either (I don’t care for AWD in my sports cars) but I get why it exists. https://jalopnik.com/lets-find-out-if-using-electric-eels-to-charge-your-tes-1836978424 Why is the rear passenger side halfshaft a different diameter than the rear driver’s side?
