DRR says that a standard ATV can release more than 20 pounds of CO2 into the atmosphere from a single tank of gas, while registering up to 80 on a decibel meter. The Stealth E-ATV quadbike is eco-friendly and lives up to its Stealth moniker. It's been developed for search and rescue personnel, ecologists and environmentalists, but is designed so that any rider can quietly enjoy all-terrain adventures.

"I was watching a news clip about the search for a lost child;the vehicles were so loud," said DRR's Kim DeCuzzi. "With UTVs and ATVs and trucks – I thought – can anyone even hear a cry for help? There has to be a better way to do this."

Currently at the prototype stage, the Stealth E-ATV can travel up to 35 miles (56 km) at full tilt before its swap-out battery pack needs some juice, but the company reckons that riders could get a full 8 hour working day on a single charge if the vehicle is used intermittently.
