New York (CNN) -- During the 90-minute ride of terror, Tamerlan Tsarnaev kept talking.

He barked out orders, detailed his hatred of Americans and asked his carjacking victim to remain calm.

Tsarnaev kept asking about the 26-year-old driver's heritage and family.

"If you cooperate, I won't kill you," said Tsarnaev, who, along with his younger brother, was a suspect in the Boston Marathon bombings and the killing of a police officer.

The Massachusetts driver, whom CNN is identifying only as Danny because of privacy and safety concerns, gave his account of the April 18 incident and described the very different behavior of Tsarnaev and his younger brother, Dzhokhar.

While the talkative Tamerlan was the ringleader during the carjacking, the quiet Dzhokhar responded to multiple orders, such as getting money from an ATM.

The only question Dzhokhar asked was how much Danny paid for his Mercedes SUV.

After the Chinese entrepreneur eventually escaped, police caught up with the brothers and engaged in a gun battle that left Tamerlan Tsarnaev dead.
