Juechter finally got a mid-engine Corvette approved for the 2020 model year \u2014 in part by arguing that the midship architecture would finally birth an all-wheel-drive Corvette to compete against similar AWD exotics from European manufacturers like Porsche and Lamborghini.<\/p>\n<p class=\"gnt_ar_b_p\">The 2024 Corvette E-Ray, unveiled Tuesday with a 160-horsepower electric motor driving the front wheels and a good ol\u2019 495-horsepower V-8 driving the rears, is the culmination of that vision. The Detroit News sat down with Juechter at GM\u2019s Milford Proving Grounds to talk about his latest toy.<\/p>\n<p class=\"gnt_ar_b_p\"><em>TDN: The E-Ray is the third model of the eighth-generation Corvette C8 after the standard Stingray and Z06. Tadge, tell us about it.<\/em><\/p>\n<p class=\"gnt_ar_b_p\">Juechter: It\u2019s a different mission than the Z06. Even though it is similarly priced, it represents a different value proposition. We\u2019ve long heard from customers they really want AWD to make it a three-or-even-four-season car. We weren\u2019t able to do that with front-engine architecture, but with mid-engine architecture, that freed up space to enable us to do it.<\/p>\n<p class=\"gnt_ar_b_p\">Starting at the inception of the C8, we thought an electrified front axle was the way to go. It\u2019s compact, and gives us a lot of efficiency. It\u2019s independent of GM\u2019s commitment to zero-emissions. We thought this would be a good idea and pleasing to customers. And it brings a new, higher-level of thinking to the Corvette. The Z06 is mission specific: it\u2019s focused on the track experience, whereas the E-Ray is an all-arounder.<\/p>\n<figure class=\"gnt_em gnt_em_img\"><img decoding=\"async\" class=\"gnt_em_img_i\" src=\"https:\/\/www.gannett-cdn.com\/presto\/2023\/01\/16\/PDTN\/561c8979-9dbb-451d-ab01-d072f03267ca-CorvetteE-Ray_fr3-4.jpg?width=660&amp;height=372&amp;fit=crop&amp;format=pjpg&amp;auto=webp\" srcset=\"https:\/\/www.gannett-cdn.com\/presto\/2023\/01\/16\/PDTN\/561c8979-9dbb-451d-ab01-d072f03267ca-CorvetteE-Ray_fr3-4.jpg?width=1320&amp;height=744&amp;fit=crop&amp;format=pjpg&amp;auto=webp 2x\" alt=\"The 2024 Chevrolet Corvette E-Ray is a grand touring model to complement the performance Z06.

With all-wheel-drive, the E-Ray is suited for all-season driving.\" data-c-credit=\"Henry Payne, The Detroit News\"><\/div>\n<\/figure>\n<p class=\"gnt_ar_b_p\">We like to say the Z06 is the scalpel \u2014 a sharp instrument for a specific purpose. E-Ray is more of a Swiss Army knife \u2014 it\u2019s good at all sorts of things. It\u2019s capable on track, but a great daily driver, and it\u2019s great in inclement weather. (It\u2019s) a car for anyone who wants an all-around daily driver.<\/p>\n<p class=\"gnt_ar_b_p\"><em>TDN: Other manufacturers have done hybrid, all-wheel-drive, mid-engine sports cars. There\u2019s the $1 million Porsche 918 and $170,000 Acura NSX that just went out of production in Ohio. How do you make this thing for just $105,000?<\/em><\/p>\n<aside id=\"gnt_atomsnc\" class=\"gnt_em gnt_em_anc\" data-g-r=\"lazy\" data-gl-method=\"loadAnc\" aria-label=\"Newsletter signup form\">\n<div class=\"label\" hidden=\"\"><\/div>\n<div class=\"container\">\n<div class=\"message\">\n<div class=\"container\">\n<div class=\"input-container populated\">Juechter: Electric motors are so compact and small. We\u2019ve done a kind of Corvette version, so if you look at the way we do our electrification, it\u2019s very Corvette-like. It\u2019s not a replica of technology that you see in other electrified vehicles, all the way down to the chemistry in the battery pouches. They are all designed for performance. Everything about this car is designed for performance.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/aside>\n<p class=\"gnt_ar_b_p\">You see the same kind of material usage you\u2019ve seen on Corvettes \u2014 composites like the battery cover is carbon fiber; our magnesium for the front-drive unit is probably the lightest in the industry; it only weighs a little over 80 pounds. This for a 160-horsepower motor.<\/p>\n<p class=\"gnt_ar_b_p\">Corvette\u2019s value proposition is part of our history. Just because we are going electrified, we don\u2019t feel like we can charge an arm and leg for that. We want to keep it a car that\u2019s reasonably accessible. It\u2019s not inexpensive, but we feel like we are giving you a really good value.<\/p>\n<p class=\"gnt_ar_b_p\">The E-Ray is a little less expensive than the Z06, but it\u2019s got the battery pack, front-drive unit and carbon ceramic brakes standard. We think we are starting down the electrified road in a very appealing way. Being light is very, very important. Batteries and drive units tend to be heavy \u2014 this car is less than 300 pounds heavier than a Z06, which shares its proportion and size.<\/p>\n<p class=\"gnt_ar_b_p\"><em>TDN: How heavy is it?<\/em><\/p>\n<p class=\"gnt_ar_b_p\">About 3,700 pounds dry weight. Heavy for a Corvette, but very light for an electrified vehicle. So we tried to keep it as elemental as we could \u2014 only use the technology in a way that enhances the driving experience. It does happen to enhance the efficiency as well, but we didn\u2019t want to burden the car with so much wiring that we lost the basic element: the ride and handling, track capability, responsiveness. We didn\u2019t want the car to feel more sluggish. We put the heaviest part of the unit, the battery, right at the center of gravity. Low, in the tunnel. So you still get that beautiful turn-in that you get from our mid-engine cars. We didn\u2019t want to lose that.<\/p>\n<p class=\"gnt_ar_b_p\">The drive-unit is pushed rearward in the front \u2014 almost in the tunnel \u2014 so we\u2019re not putting a lot of extra weight on the nose. So it still drives and feels like a C8.<\/p>\n<p class=\"gnt_ar_b_p\"><em>TDN: You still have a full frunk. How did you package that?<\/em><\/p>\n<p class=\"gnt_ar_b_p\">Juechter: Everyone thought we would have to give up the front trunk. We didn\u2019t want to do that. As an all-around vehicle, you want to be able to take this car cross-country. It&#8217;s available in coupe and convertible. You put the top down and you don\u2019t lose any trunk space. We wanted to preserve the front and rear cargo for the customer, so you don\u2019t have to leave anything at home. The frunk is almost exactly the same as the Stingray.<\/p>\n<figure class=\"gnt_em gnt_em_img\"><img decoding=\"async\" class=\"gnt_em_img_i\" src=\"https:\/\/www.gannett-cdn.com\/presto\/2023\/01\/16\/PDTN\/acc8bfe2-86f3-4f3c-892d-54414c184522-CorvetteE-Ray_frunk.jpg?width=660&amp;height=372&amp;fit=crop&amp;format=pjpg&amp;auto=webp\" srcset=\"https:\/\/www.gannett-cdn.com\/presto\/2023\/01\/16\/PDTN\/acc8bfe2-86f3-4f3c-892d-54414c184522-CorvetteE-Ray_frunk.jpg?width=1320&amp;height=744&amp;fit=crop&amp;format=pjpg&amp;auto=webp 2x\" alt=\"The frunk in the 2024 Chevrolet Corvette E-Ray maintains the same volume despite the addition of a front motor.\" data-g-r=\"lazy\" \/><\/p>\n<div class=\"gnt_em_img_ccw gnt_em_img_ccw__cap gnt_em_img_ccw__crd\" data-c-caption=\"The frunk in the 2024 Chevrolet Corvette E-Ray maintains the same volume despite the addition of a front motor.\" data-c-credit=\"Henry Payne, The Detroit News\"><\/div>\n<\/figure>\n<p class=\"gnt_ar_b_p\"><em>TDN: You also kept the pushrod, 6.2-liter V-8 in back like the Stingray.<\/em><\/p>\n<p class=\"gnt_ar_b_p\">The small block V-8 has been a part of the Corvette legacy since 1955 and we actually wanted to use electrification to enhance what people love about that small block. So you get all the sound and character \u2014 we don\u2019t take anything away from that. However, we tell people this is a 6.2-liter, almost-500 horsepower small block, but the way this car drives is like an 8-liter small block with almost 650 horsepower. Except it has none of the downsides \u2014 you don\u2019t feel the weight, you don\u2019t lose the efficiency. This car gets fuel efficiency as good or better than a Stingray even though it has all the exotic proportions \u2014 (13.5-inch wide) rear tires. So you would think a car with this kind of looks, presence and performance would be a gas guzzler and it\u2019s not.<\/p>\n<p class=\"gnt_ar_b_p\"><em>TDN: I\u2019ve been out here four-wheel drifting on Black Lake (the 67-acre asphalt testing pad at GM\u2019s Proving Grounds) with your performance engineer Aaron Link. How do you tell E-Ray apart from a Z06?<\/em><\/p>\n<p class=\"gnt_ar_b_p\">There are some subtle differences. This car comes standard with more of a monochrome look, so fewer of the carbon accents pieces like you would find on a Z06. But the bodywork is the same as the Z06. Everybody loves it. We have unique badging, unique forged wheels. Because the outboard exhaust is ideal for the small-block V-8, we retain that. That is quite distinct from the Z06.<\/p>\n<figure class=\"gnt_em gnt_em_img\"><img decoding=\"async\" class=\"gnt_em_img_i\" src=\"https:\/\/www.gannett-cdn.com\/presto\/2023\/01\/16\/PDTN\/92ee82d5-f341-4607-8412-2bf9731e1f7a-CorvetteE-Ray_rr.jpg?width=660&amp;height=372&amp;fit=crop&amp;format=pjpg&amp;auto=webp\" srcset=\"https:\/\/www.gannett-cdn.com\/presto\/2023\/01\/16\/PDTN\/92ee82d5-f341-4607-8412-2bf9731e1f7a-CorvetteE-Ray_rr.jpg?width=1320&amp;height=744&amp;fit=crop&amp;format=pjpg&amp;auto=webp 2x\" alt=\"You'll be able to tell the 2024 Chevrolet Corvette E-Ray from the Z06 by the E-Ray's corner-mounted quad pipes (the Z06's pipes are center-mounted).\" data-g-r=\"lazy\" \/><\/p>\n<div class=\"gnt_em_img_ccw gnt_em_img_ccw__cap gnt_em_img_ccw__crd\" data-c-caption=\"You'll be able to tell the 2024 Chevrolet Corvette E-Ray from the Z06 by the E-Ray's corner-mounted quad pipes (the Z06's pipes are center-mounted).\" data-c-credit=\"Henry Payne, The Detroit News\"><\/div>\n<\/figure>\n<p class=\"gnt_ar_b_p\"><em>TDN: That\u2019s because of the different engines?<\/em><\/p>\n<p class=\"gnt_ar_b_p\">Yes. The (5.5-liter, overhead-cam V-8 in the) Z06 really cried out for a different solution. We didn\u2019t think we\u2019d have two different solutions, but as we got into the hardware \u2014 and listened to the car \u2014 we realized we needed a unique solution. One good thing that came out of COVID is that it gave us down time \u2014 when the plants were shut down and we were working from home. We still had people coming into the Milford Proving Grounds trying to architect the exhaust and figure out what was the ideal exhaust for this engine. So there was a little pause in the program and we took advantage.<\/p>\n<p class=\"gnt_ar_b_p\"><em>TDN: Let\u2019s talk about the interior. Google Automotive Services is now running the infotainment system, and you\u2019re doing something different with the drive modes.<\/em><\/p>\n<p class=\"gnt_ar_b_p\">We wanted to give people other feature functionality with the electric motor. Anybody who has driven a Corvette knows that when you start it, it\u2019s not a subtle thing. The engines are very expressive, very powerful. They have a relatively open exhaust. So they are noisy, but there are times when you don\u2019t want to wake your neighbors when you go into work early.<\/p>\n<figure class=\"gnt_em gnt_em_img\"><img decoding=\"async\" class=\"gnt_em_img_i\" src=\"https:\/\/www.gannett-cdn.com\/presto\/2023\/01\/16\/PDTN\/e89b30f0-7b01-4ff1-8fa0-1b71a7554693-CorvetteE-Ray_cockpit.jpg?width=660&amp;height=372&amp;fit=crop&amp;format=pjpg&amp;auto=webp\" srcset=\"https:\/\/www.gannett-cdn.com\/presto\/2023\/01\/16\/PDTN\/e89b30f0-7b01-4ff1-8fa0-1b71a7554693-CorvetteE-Ray_cockpit.jpg?width=1320&amp;height=744&amp;fit=crop&amp;format=pjpg&amp;auto=webp 2x\" alt=\"The driver-focused cockpit of the 2024 Chevrolet Corvette E-Ray includes a Z-Mode button on the steering wheel, a new Stealth Mode screen, and a Charge+ button on the side console for max battery regen.\" data-g-r=\"lazy\" \/><\/p>\n<div class=\"gnt_em_img_ccw gnt_em_img_ccw__cap gnt_em_img_ccw__crd\" data-c-caption=\"The driver-focused cockpit of the 2024 Chevrolet Corvette E-Ray includes a Z-Mode button on the steering wheel, a new Stealth Mode screen, and a Charge+ button on the side console for max battery regen.\" data-c-credit=\"Henry Payne, The Detroit News\"><\/div>\n<\/figure>\n<p class=\"gnt_ar_b_p\">So we thought: why not use the electric ability to be a neighborhood exit feature? We\u2019ve had Stealth modes on Corvettes before, which tone down the noise \u2014 but we never went completely silent. So in this case, there is a mode where \u2014 before you start the car \u2014 you can actually put it in Stealth Mode and it will run on battery power alone.<\/p>\n<p class=\"gnt_ar_b_p\">You can back the car out, run a few miles, get out on the highway, and then when you step on the gas \u2014 or exceed 45 mph \u2014 the internal combustion engine will light off and you\u2019re back to regular performance hybrid operation. We think a lot of people will really appreciate that feature.<\/p>\n<p class=\"gnt_ar_b_p\"><em>TDN: Thanks, Tadge.<\/em><\/p>\n<p class=\"gnt_ar_b_p\"><em>Henry Payne is auto critic for The Detroit News.
