Harris County Sheriff's deputies say the crash happened just after 2:30 a.m. near Loch Katrine Lane.
Video from the scene shows the destroyed BMW split in half, barely recognizable after colliding with a Hummer.

The crash happened when the Hummer crossed the intersection at Loch Katrine and hit the BMW, causing it to spin before hitting a steel light pole, deputies said.
According to the sheriff's office, 16-year-old Tristan Sanders was sitting in the back seat of the BMW and was killed. The 16-year-old driver and 18-year-old passenger are both in the hospital in serious condition.
Family on the scene says Sanders was a star football player at his high school in north Texas, and they had just moved here because he was transferring to a Houston-area school.

The driver of the Hummer was not seriously injured, officials say.
Authorities believe the 47-year-old Hummer driver, Carlos Guillermo Ayala, was under the influence, and say he's been charged with driving while intoxicated. They say speed was a factor in the crash.
Harris County District Attorney's Office Vehicular Crimes Chief Sean Teare says Ayala could face additional charges pending a blood test.
"It's pretty catastrophic damage," Sgt. Gilbert Guien said. "The BMW actually split apart."
Both directions of Highway 6 were closed for hours and traffic was detoured at Kieth Harrow.
