2024 Corvette ERay – GM’s First Electrified Corvette
The Challenge
The 2024 E-Ray introduced a major first: electric all-wheel drive in an iconic American sports car. But with innovation came complexity.
How could we help drivers understand a dual power source, manage new behaviours, and unlock the full performance potential of a performance hybrid system—without overwhelming them?
Design Goals
To make hybrid performance intuitive, engaging, and distinctly Corvette, we focused on:
Explaining complex power flows simply and visually
Delivering real-time feedback for electric and gas propulsion
Creating a premium, Corvette-worthy in-vehicle experience
Enabling new behaviours like EV-only starts through intuitive UX
“Built to reveal, not overwhelm—translating advanced technology into a language every driver understands.”
As lead designer, I collaborated closely with performance engineers, software architects, and brand teams to craft the E-Ray’s first-of-its-kind hybrid interface.
I owned the user flow, wireframes, and final UI design—translating technical vehicle logic into an elegant, in-dash experience that drivers could understand and trust.
Key Features & Innovations
Real-Time Power Flow Visualization
A dynamic animation system shows how and when the front electric motor and rear internal combustion engine contribute to propulsion, regen, or charging—clearly illustrating a complex hybrid architecture.
‘Stealth Mode’ Activation
We created a seamless user experience for enabling EV-only starts, giving owners an intuitive way to quietly move the car—Corvette’s version of a “secret handshake.”
Performance-First Language
Rather than overwhelming drivers with technical jargon, the interface speaks the language of performance: front assist, torque split, regen status—refined for clarity.
Rapid Prototyping with Engineers
Iterative testing with Corvette performance engineers helped ensure the app was more than just beautiful—it had to be accurate and track-capable.
Design Highlights
The E-Ray App features a live, animated power diagram that clearly shows how the hybrid system responds in real time. Every detail—from the custom Corvette branding to the performance-focused UI language—was crafted to feel intuitive and purposeful.
We introduced a dedicated Stealth Mode flow, enabling EV-only starts with ease, and designed EV usage metrics specifically for the expectations of sports car drivers. Whether charging trough the road or leveraging the Charge+ feature, the interface was built for clarity in both driving and charging states.
Impact & Outcomes
The E-Ray app made complex hybrid tech clear and intuitive, giving drivers confidence and control.
As Corvette’s first hybrid interface, it earned praise from media and GM leadership—including Mark Reuss—and set a new UX standard for future electrified performance cars. Now live in the 2024 E-Ray and revised for the 2026 model, it’s built for broader use across GM platforms.
The E-Ray App shows what’s possible when design, engineering, and emotion align. It doesn’t just explain the hybrid system—it elevates it, giving drivers insight, control, and pride in a new era of performance.
