You’ve probably seen the headlines about Mary Barra. She’s the face of General Motors, the CEO who navigated the "Switchgate" crisis and steered the company toward an all-electric future. But if you’re looking for the person actually turning the wrenches on the company’s massive portfolio, you’ll find Mark Reuss. He is the President of GM Motors, a title he’s held since 2019, and honestly, he’s not your typical corporate suit.
Most people think of a "President" in a massive conglomerate as a numbers guy. Someone who sits in a glass office staring at spreadsheets and EBITDA margins. That’s not Reuss. He is a certified "car guy"—a mechanical engineer who grew up in the shadow of Detroit’s smokestacks. He’s also the son of Lloyd Reuss, who served as GM President in the early '90s.
But following in his father’s footsteps wasn’t a guaranteed path. Mark started as a student intern back in 1983.
Why the President of GM Motors is More Than an Executive
When we talk about the President of GM Motors, we’re talking about the person responsible for every single vehicle that rolls off the line. This includes global product development, quality control, and even the high-stakes world of motorsports. While Barra handles the high-level strategy and investor relations, Reuss is the one making sure the Cadillac LYRIQ doesn’t just look good but actually drives like a Cadillac should.
He’s known for being incredibly hands-on. In October 2024, he didn't just sign off on a press release for the 2025 Chevrolet Corvette ZR1; he actually got behind the wheel. Reuss drove the car to a blistering 233 mph, setting a world record for the fastest production car under $1 million.
How many other 60-year-old presidents of Fortune 500 companies are doing that? Not many.

It’s that kind of grit that defines his tenure. He isn’t just managing a brand; he’s trying to save the soul of American manufacturing. It hasn't always been a smooth ride, though. People love to bring up the 2018 Detroit Grand Prix. Reuss was driving the pace car—a Corvette ZR1—and he lost it in the first corner. He crashed right in front of the cameras. It was a PR nightmare.
"I'm okay. I'm just incredibly embarrassed," he essentially told the media afterward. But here’s the thing: he got back in the pace car the very next year. In the pouring rain. He didn't blink. That says more about the current President of GM Motors than any quarterly earnings call ever could.
The Massive Shift to Electric
The real challenge for Reuss right now isn't hitting 233 mph on a test track. It's the "Ultium" platform. This is the modular battery architecture that GM is betting its entire future on. If it fails, the company fails.
GM has been taking some massive hits lately. In early 2026, reports surfaced that the company took a $7 billion charge related to its EV transition. That’s a staggering amount of money. The skepticism is real. Critics argue that the pivot to electric is happening too fast, or perhaps not fast enough, depending on who you ask.
Reuss’s job is to bridge that gap. He oversees:

Recent Wins and 2026 Goals
Just this week, in mid-January 2026, GM snagged the "Overall Manufacturer Loyalty" award from S&P Global Mobility for the 11th year in a row. Reuss pointed out that this isn't just a trophy for the shelf. It means that when people buy a Chevy or a Cadillac, they’re coming back.
But "loyalty" in 2026 looks different than it did in 1996. Now, it’s about software.
Reuss is currently pushing the integration of conversational AI into vehicles. You’ve likely heard about the partnership with Google to use Gemini (the AI, not the star sign) to handle voice commands. They are also eyeing 2028 for "eyes-off" driving on the Cadillac Escalade IQ.
The F1 Dream
One of the most surprising things about the President of GM Motors is his obsession with Formula 1. Under his leadership, Cadillac is making a serious run at the F1 grid.
A lot of people thought it was a vanity project. But Reuss has been adamant that F1 is the ultimate "innovation lab." Just days ago, he was at the new GM headquarters at Hudson’s Detroit—a stunning new facility that replaced the old RenCen—unveiling a special edition livery for the Cadillac F1 team’s shakedown in Barcelona.

He’s betting that the prestige of F1 will rub off on the consumer cars. If you can build a power unit for a Grand Prix car, people might trust your electric SUV battery a bit more. That’s the logic, anyway.
Actionable Insights for the Industry
If you are following the trajectory of the President of GM Motors, there are a few key takeaways you can actually use to understand where the market is headed:
- Engineering over Buzzwords: Watch Reuss’s LinkedIn or public appearances. He talks about torque, aerodynamics, and thermal management. In a world of "AI-first" marketing, GM is still trying to lead with mechanical excellence.
- The Hybrid Pivot: Despite the "all-electric" mantra, pay attention to how Reuss discusses hybrids. As of late 2025, the company has had to soften its stance to meet actual consumer demand. If the President of GM is talking about "flexibility," the industry is likely cooling on a pure-EV-only 2030 goal.
- Regional Strength: GM is doubling down on North American production. With shifting federal policies and tariffs becoming a major talking point in 2026, Reuss’s focus on domestic supply chains is a roadmap for other manufacturers.
Mark Reuss is a legacy executive who is trying to prevent GM from becoming a legacy company. He’s a guy who crashes pace cars and then breaks speed records. He’s an engineer in a world of financiers. Whether he succeeds in turning GM into a tech powerhouse remains the biggest question in Detroit.
To stay ahead, keep an eye on the technical milestones he highlights rather than the broad corporate promises. When Reuss talks about a specific suspension tune or a battery chemistry change, that’s where the real strategy is hidden. Don't just watch the CEO; watch the President. He’s the one actually building the cars.
