In cooperation with General Motors, Leno's EcoJet was actually built right inside his garage. It has 650 horsepower and utilizes a Honeywell LTS101 turbine engine, which is usually used for attack helicopters.
Upon walking up to the EcoJet, Tyson asks, "Why is it called Eco? This doesn't look very 'eco' to me."
Leno explains that it runs on renewable energy, biofuels. The major mechanics are located in the rear of the car, and exhaust comes out from the top.
"It would've been way cooler if flames came out the back," Tyson says as he looks over the car. "I'm just saying."
Leno is quick to shoot down the idea, saying, "I'm not trying to scare children. We're trying to make a transportation vehicle here."
With their helmets on, they climb inside the EcoJet for a drive.
Tyson shouts, "Show me what you got!"
Leno does. Soon, they're blasting down the runway. Everything seems to be going smoothly as they top 100 miles per hour. The engine is running well. The tires are sturdy. Tyson is squealing with delight.
