With the addition of hybrid propulsion and an all-wheel drivetrain, the 2024 Corvette E-Ray has thrown a wrench into what the Chevy Corvette has traditionally been. Regardless of the controversy this paradigm shift brings, it’s hard to deny how impressive the technology behind the C8 E-Ray is, including its 1.9 kWh battery pack. To help articulate how forward-thinking the hybrid Vette is, executive chief engineer Tadge Juechter recently provided some insight into the battery’s characteristics.
Speaking to SAE International in a recent interview, Juechter pointed out three distinctive C8 Corvette E-Ray charging features, including coast regen, brake-apply regen, and through-the-road charging. In regards to coast regen, every time the driver lifts off the throttle, the batteries recover a small amount of energy. According to Juechter, this is not one-pedal driving as seen in other EVs, but rather more similar to that of an ICE’s compression braking.
Next up is the brake-apply regen. When the driver begins to apply the brake, progressive regen provides the expected deceleration. Similar to that of most other electric vehicles, as more braking is applied, friction brakes add more stopping power. The C8 E-Ray adds an electric brake booster to create a seamless transition regardless of braking degree.
Finally, under certain circumstances, the Corvette E-Ray will command more output than the driver initiates with the throttle. The electric motor then switches to generator and regen mode to provide the driver an intuitive feel and recharge the battery while the vehicle is in motion.
These three techniques allow the Corvette E-Ray’s battery pack to be quickly recharged. In addition, the Charge+ mode applies aggressive regen to charge the battery from close to empty to full in about 2 to 3 miles. In normal driving situations, Juechter added that it’s actually difficult to fully drain the battery.
As a reminder, the 2024 Corvette E-Ray was officially unveiled earlier this week. Slotting in between the entry-level C8 Stingray and track-focused C8 Z06 variants, the E-Ray combines the naturally aspirated 6.2L LT2 V8 engine, rated at 495 horsepower and 470 pound-feet of torque, with a front-mounted electric motor that develops 160 horsepower and 125 pound-feet. This raises total output to 655 horsepower. A revised dual-clutch, eight-speed automatic transmission (RPO code MLH) serves as the only transmission option.
The 2024 Corvette E-Ray will go on sale in late 2023, and will be built at the GM Bowling Green plant in Kentucky, alongside the Stingray and Z06 models. Both a Coupe and Convertible body style will be on offer, with a starting MSRP of $104,295 for a Coupe in 1LZ configuration.
