A teenage Boston University undergrad with no driver’s license drove his $126,500 Maserati GranTurismo over the rain-soaked streets of the Back Bay yesterday at 100 mph, prosecutors said.

The speed limit on Beacon Street is digitally posted at 30 mph. The Italian sports car, which goes from 0 to 60 mph in five seconds, has a top speed of 177 mph, according to the manufacturer.

Zeguang Xu, 19, an undergraduate student at BU’s College of Arts and Sciences, pleaded not guilty today in Boston Municipal Court to charges of operating without a license, providing a false name to police, speeding, failure to stop, and negligent operation. He was released from custody after posting $1,000 bail.

“High speeds, poor driving conditions — this could have been a recipe for disaster,” Suffolk District Attorney Daniel Conley said. “We’re very fortunate no one was hurt, including the driver himself.”

Xu had a female passenger with him when he was arrested. Prosecutors said police allowed her to take the car after confirming Xu was the owner.

Xu, who prosecutors said is a Chinese national, did not immediately respond to a request for comment this afternoon.

Colin Riley, spokesman for BU, said he could not speak specifically about Xu’s status, citing privacy laws, but told the Herald, “Certainly what is described here is reckless and dangerous. We hold students accountable when they’re arrested for violations of student-conduct policies. We’ll get the police report and go from there.”

Prosecutors said police saw the blue sports car blow by on Beacon at 2:20 p.m. Wednesday “while it was raining and the roadway was wet.”

Xu was allegedly seen driving through a red light at Beacon and Fairfield streets — the same intersection where Jessica Campbell, a senior analyst at Kantar Retail, and John “Jack” Lanzillotti, the Emmy Award-winning manager of Red Sox Productions and Game Operations, were killed when Yemen native Mohamed Alfageeh, 30, allegedly ran a red light and flipped his SUV June 21. Alfageeh is scheduled to go on trial May 18 on two counts of motor vehicle homicide.

Xu was busted when he hit traffic at Beacon and Massachusetts Avenue, prosecutors said.

Police said he told them he’d left his wallet and driver’s license at home and that the car belonged to a friend. It’s alleged Xu also gave police the name and birth date of someone else. When confronted, prosecutors said Xu produced a wallet and provided his BU ID.
