Chapter 1: Who is John Hennessey and what inspired his passion for cars?
John Hennessy, founder and CEO of Hennessy Performance Engineering, a leader in high-performance vehicle tuning. For three decades now, he's been pushing cars beyond their limits.
My parents didn't have much. That was the driver towards entrepreneurship. I kind of had to find a way to make money. There wasn't really any choice around that. I'm a little bit of a Warren Buffett when it comes to horsepower. I look for value. I look for undervalued vehicles where there's more potential that can be extracted.
Chapter 2: How did John Hennessey's early entrepreneurial spirit develop?
you
John Hennessy, founder and CEO of Hennessy Performance Engineering, a leader in high-performance vehicle tuning. For three decades now, he's been pushing cars beyond their limit. He's already set a world speed record. We'll talk about it. And now as a Venom F5, he's chasing the 300 mile per hour. Oh my God, John. First of all, why cars? And maybe take us back in time to your childhood.
When did this love start?
Maybe it started when my dad was younger and I'm the first born child and he had a 1964 Pontiac GTO muscle car. And I'm told that I would sit in his lap and he would let me drive and shift through the gears. So I think it started before I could remember.
So it's something that's been, you know, now 62 years later, I've been programmed into my DNA and now my kids, and now we had our first grandchild a few weeks ago. So maybe in his DNA as well.
Oh, my God. Congratulations, first of all. So you and Hope, we'll talk about her as well, speaking of more car lovers. So take us back in time to your childhood. What fueled you into this drive and success? And was there like a specific moment?
Yeah, I can think of several. When I was in junior high, I was hanging out with my friends.
few streets away from home i knew i was supposed to be home at a certain time i kind of blew it off and then my dad had another muscle car i think this is a 1968 pontiac gto he comes flying down the street he rolls down the window and i'm over talking to my buddies he's like hey you're supposed to be home i'm like okay okay i'm coming so i could come to go get in the car
And he basically just slaps into the gear and doesn't let me even open the door. And he does this big burnout, spinning the tires, making a big cloud of smoke for a couple hundred feet, at which point I knew I was in big trouble. But then again, I'm probably 12 or 13 at the time. And I look over at my buddies, they're all like,

Chapter 3: What were John Hennessey's first steps into car racing?
And at that point in time, I had a friend of mine who had a Corvette. an old 73 Corvette, which had the T-top roof panels that would come off. And I had this idea to start a business to make these soft bags that you could put the roof panels in because nobody offered that at the time. And so I was trying to earn up money at that working at Bennigan's so I could start that business.
That didn't end up working out, but I just kept trying different things. And then a few years later, some guy that I'd met said, well, hey, there's this new businesses back in the 80s where
commercial real estate and schools and hospitals used a lot of asbestos for insulation on pipes and in different construction materials because of the fire retardant properties, but they were also a carcinogen and they would cause cancer. So that was kind of a new industry back then of removing asbestos from commercial buildings.
And so I went to some schooling, learned about that, started a business. Went and did that and actually had some success from that. And so I wasn't married yet. I wasn't dating my wife yet. So I had a little bit extra money and decided to start buying some cars and tinkering with the cars and decided to dabble in the car racing.
Did your parents force you to do all these jobs, like the 3 a.m. thing, or is that something that you wanted to do?
I was always motivated. Again, they were very matter-of-fact about it. They're like, well, we don't have money for that. If you want to go to McDonald's, we don't have money for that. Okay, you've got shoes, but if you want those nicer shoes, You're going to have to figure out how to make some money. Yeah. And at the time, my dad had an issue with PTSD from the Korean War.
So he had an addiction issue and he wasn't working a lot of the time. My mom had to really work to support the family. So I'm like, I got to kind of at least do my part. At least, you know, if I want to have a car or a motorcycle or go and do stuff with my friends, I kind of had to find a way to make money. There wasn't really any choice around that.
Amazing. So to some extent, it was also a huge gift.
Yeah. Yeah. My mom passed away recently and her funeral was last week. And it was definitely a gift that I got from both of them. And when I had my newspaper route at the hospital up in Kansas City, they would generally give me a ride there. They would get up early to get me there so I could go pass out newspapers and make a little bit of money. They were supportive and encouraging.

Chapter 4: How did John Hennessey transition from racing to founding Hennessey Performance?
And so I did that race. Then I did Pikes Peak. And these days, I don't have a budget for a crew. I don't have a budget for, I didn't even know I needed a crew. I didn't even know I needed a truck or a trailer. And I would show up to Pikes Peak and here are major like IndyCar type teams, like NASCAR type teams with major crews.
And I'm just this guy over here pulling my wheels and tires out the back. And and luggage and whatnot. Actually, I went and picked my wife up from the airport in Colorado Springs for the race. Anyway, I didn't win anything at Pikes Peak, but I competed, I finished. She and I went to Aspen for a little vacation afterwards. We were engaged at the time.
And then I also thought, well, now that I've got a roll cage in my car, I thought I wondered if there was a class that I could compete at at the Bonneville Slot Flats where they would do the top speed stuff. And so I got a copy of the rule book. I found a class that I fit in. And so in August, so that same year, this is 1991. So I do the Nevada Open Road Challenge in May.
Then I did Pikes Peak in July. Then I went to Bonneville in July. August. And I set a two-way average there of 177 miles an hour, which in today's terms doesn't sound very fast. But doing that at Bonneville, it's very difficult. So I set a record there, drove it there, drove it home. And then they do another open road race in September. That's called the Silver State.
And then I got second place overall in that race. And my average speed was 167 miles an hour so i went a little bit faster so anyway i do all these races and at the time i'm not doing my asbestos abatement business as much i'm engaged we're in love we're having fun we get married go on the honeymoon
And I come back from the honeymoon and I'm looking at my bank balance and I'm like, man, I used to have a lot more money in the bank earlier this year before I started all this car stuff and continuing the romance and buying a house and so on and so forth. And I mentioned this to some racing buddy of mine. He's like, oh, you just learned the first rule of car racing. I said, what's that?
He says, if you want to make a small fortune in car racing, you start with a larger fortune. And so this whole year I'm watching my bank balances. Well, I'm not watching it because I know what it's doing and I don't want to be reminded that it's going in the wrong direction because I was having fun. At which point I thought to myself, well, I really like the car business.
I really like modifying cars. I think I'm pretty good at it. I think I'm a pretty good driver. I want to keep doing some of the racing. And I thought, you know, guys before me, guys like Carroll Shelby with Ford, a guy named Alois Roof, who's still alive, who's a very famous Porsche modifier, who I'd started reading about back when I was at the magazine rack when I was nine years old.
And another gentleman from here in the US, a guy named Reeves Calloway, who modified Corvettes and Chevrolet products. Those guys seemed to have made a career out of modifying cars for other people. And I thought,

Chapter 5: What challenges did John Hennessey face in building his car modification business?
And he worked in the public relations department at Mitsubishi. And he brought the journalist to write the article, See Van Tune. And so these guys were like, oh, they kind of diffused the situation. And they were like, oh, we're going to help John. We've got the minivan over here. We can tow him around.
I'm telling you this whole long story is Joe was been within the PR department at Mitsubishi for a few years. And he said, after Bonneville, he says, Hey, look, after Bonneville, why don't you come down to LA? I'll take you around and I'll introduce you to like the editor at Motor Trend and the one editors at Car and Driver. And I'm like, wow, I've read about these guys.
And he said, Hey, by the way, If they like you and if they ever ask to do a story on one of your vehicles and they write something nice about your vehicle, your phone will ring and people want to buy your product. I'm like, okay, that sounds good. So went and did all that and gave my car to a couple of these different media outlets and
And a couple months later, this nice little article came out and my phone started ringing. I didn't know what earned media was. I didn't know what PR was. But my friend Joe, and again, we talk all the time. We're still friends to this day. He just retired as the VP of communications for Chevrolet. So he's been in the car industry most of his career.
But Joe taught me a very, very valuable lesson very early on that This is before the internet. This is before YouTube, social media. So car magazines, they could make you or break you back in the day. So I would just foster relationships with these guys. Anytime over the years, they would call me up and say, hey, we need a fast car to do XYZ. I was always... Yes, I'll do it. Yes, I'll do it.
Yes, I'll do it. But for those first five years of the business, our bank balance never fluctuated much above $15,000 and not much below $5,000. And all I'm trying to do is just make enough money to help pay our house payment and get to the next race. Well, then after our first child came along, I'm like, all right, I got to make this into a real business. This can't be a hobby business.
But for those first five years, I kept thinking, is this the year that cool cars is out? Is this the year that people are like, you know, fast cars, that's just kind of a fad. I'm ready to move on to something else. And that's kind of what I thought for the first five years. But over time, I thought we kept getting more notoriety.
And then a vehicle came along, the Dodge Viper, and we started modifying the Viper, which was a pretty radical car back in the 90s, a V10 with 400 plus horsepower, and we took it to 500 horsepower and beyond. So we got a lot, a lot, a lot of media coverage. I'm talking about dozens of car magazines and many, many covers. I mean, probably dozens of covers of magazines.
And people seem to kind of know who we were. So this is maybe now we're five, seven years into this. And I thought, are we a brand? Are we starting to become a brand? People seem to kind of know who we are. And at the time, different automotive companies, I would read about brand managers. It was kind of a term that they used back then.

Chapter 6: How did media relationships and branding impact Hennessey Performance?
And now we're all scrolling all these little short videos that we get fed all day long, right? So yeah, however people want to consume their entertainment. I always tell people, I've been saying this for years, that our company, Hennessy, is as much in the entertainment business as we are in transportation.
If you need transportation, you can go buy a brand new vehicle from most manufacturers for... $35,000, $40,000 that's safe, that's reliable, cold air conditioning, has all the connectivity. It will get you where you want to go. So every dollar spent over $40,000 is based upon entertainment and passion.
People come to us, they want us to entertain them, to give them something interesting, something that's different, something that's fun. They can either enjoy themselves, share with their family and friends.
And it's probably also status and coolness and other things.
I never, ever thought of way back when. But yeah, there is definitely a status factor for whether you're buying a Mercedes, a Rolls Royce, a Ferrari, and now even Hennessy. We're a very unique American brand. And I think people, not just in America, but around the world, do identify with the American high-performance cool factor that we deliver.
Well, I hope you enjoyed this conversation as much as I did. If you did, please share it with friends. This really helps us continue to bring amazing guests. Also, if you are feeling stuck or simply want more from your own career, watch this 30-minute training. I know it's going to help. It's leapacademy.com slash training. That's leapacademy.com slash training.
And I will see you in the next episode of The Leap Academy with Ilana Golan Show. So let's talk about this because at some point, I don't know the exact year, but you decide this insane undertaking, which is to create your own car. That's a huge undertaking. Now you're competing with really big players. It's very expensive. Tell us a little bit about that decision.
Before the Venom F5, we built a car that was about 90% our own called the Venom GT. So if you go back to... This is almost 20 years ago. Road and Track invited us to a test where they were having a shootout. The magazine wanted to get some of the fastest cars on earth together on a runway to see which car could go from zero to 200 miles per hour in the shortest amount of time.
We brought a Venom 1000 Viper. There were several other fast cars there, Lamborghini, Mercedes SLR. The fastest car besides our car was the Bugatti Veyron. 1,000 horsepower, million dollar plus car. At the end of that contest, we beat the Bugatti by four seconds. So we're on the cover of the magazine. It's a great article. It's good for business. It's great for the brand.
