Decades of power, American ingenuity
Chevy unleashes first all-wheel-drive, hybrid, 655-hp Corvette at 70
The Chevrolet Corvette turned 70 years old in January, and in celebration, the iconic supercar showcased its first hybrid, all-wheel-drive model.
The $104,295, 2024 Corvette E-ray expands the mid-engine, C8 model’s offering with a grand touring version to complement its ferocious, rearwheel-drive, $109,295 Z06 performance model and standard, $65,895 Stingray.
The E-ray and Z06 share a wider track and more aggressive body panels compared to the base car, but they diverge under the skin. With a Stealth mode that runs on the battery alone and all-season, AWD grip, E-ray offers more refinement for the daily driver. A $111,2954 hard-top convertible version of the E-ray will also be available when the hybrid Vette goes on sale late this year.
Not that the E-ray lacks performance. The Detroit News got a ride along in the E-ray at General Motors’ Proving Grounds to witness its awesome power and all-wheel grip on a cold January day.
“We’ve long heard from customers they really want AWD to make it a three-or-even-four-season car,” said executive chief engineer Tadge Juechter at Milford, Michigan.
“We weren’t able to do that with front-engine architecture, but with mid-engine architecture, that freed up space to enable us to do it.”
With an electric motor up front and a 6.2-liter V-8 driving the rears, E-ray is the quickest Corvette in a straight line yet, accelerating from 0-60 mph in just 2.5 seconds. The hybrid-electric drivetrain makes a combined 655 horsepower and 595 pound-feet of torque (the e-motor’s 160 horsepower complementing the small-block V-8’s 495 ponies).
The Z06’s high-revving, 8,500-rpm, Gt3-racing-derived, 5.5-liter V-8 — the most powerful, naturally-aspirated production engine made — makes 670 horsepower and 470 pound-feet of torque for a 2.6 second 0-60 dash. The base, 6.2-liter, 495-horse Stingray also boasts a sub-3-second 0-60 number at 2.9.
Paired with Z06, Juechter says E-ray “splits the family” in similar fashion to Porsche, which offers parallel grand touring and track-focused models. Think of the all-wheel-drive 911 Carrera 4 compared to the rearwheel-drive 911 GT3, for example.
In prior generations, Corvette has expanded on its standard model with three performance variants: Grand Sport, Z06 and ZR1. With the addition of E-ray, The Detroit News anticipates the eighth-generation Corvette lineup will include six trims — including a new Zora hypercar at the summit that will combine electric power, AWD and a twin-turbo 5.5-liter V-8 for more than 1,000 horsepower.
The 70th birthday celebration is no coincidence. GM sees the hybrid Vette not just as a game-changer with its unique talents, but as a bridge to an electric future where all of the General’s products will be battery-powered.
Juechter noted the similarity to Porsche’s offerings but for thousands of dollars less. A Porsche Carrera 4 starts at about $115K and a 911 GT3 at $170,000. Significantly, Porsche does not offer a hybrid version. And with the $170,000 Acura NSX hybrid exiting the market at the end of last year, the E-ray is the only electrified supercar in the market for less than $200,000. Other hybrid models range from the $237,500 Mclaren Artura to the $2,640,000 Lamborghini Countach.
At 2.5 seconds, the E-ray beats the Mclaren and Lamborghini to 60 mph and nearly matches the $524,815, 969-horsepower, three-motor, twin-turbocharged, 4.0-liter V-8-powered Ferrari SF90 hybrid’s 2.3-second sprint.
The E-ray achieves its “bargain” status by choosing carefully from the family toolbox.
The hybrid Vette shares its fiberglass body with Z06, which was widened
3.6 inches from the base Stingray to handle more power with bigger tires. E-ray options the same massive, 11inch front and 13.5-inch rear Michelin Pilot Sport 4S summer tires that are standard on the Z06. The base tire is a Michelin Pilot Sport all-season wrapped around staggered, 20-inch front and 21-inch rear rims.
Obsessed with lightweighting — at 3,774 pounds, the E-ray coupe weighs about 300 pounds more than Z06 — engineers kept the powertrain simple compared to three-motor, torque-vectoring systems found in competitive hybrids. The 1,609-horsepower motor and 1.9-kwh battery were developed exclusively for the E-ray application. Even the lithium-ion, 12-volt battery (which operates the car’s electronics) is bespoke to reduce weight.
Under the rear bonnet is Corvette’s workhorse, 6.2-liter, push-rod V-8 making 495 horses. E-ray is the only hybrid model that GM offers.
