Mexico had never beaten Germany in a competitive match but was transformed from the team that lost to the Germans in last year's Confederations Cup, conceding twice in the opening eight minutes of the 4-1 defeat.
In a packed Luzhniki Stadium with an estimated 30,000 Mexicans in attendance, 22-year-old winger Hirving Lozano slotted a low shot past the diving German goalkeeper and into the back of the net in the 35th minute of the match, sending the thousands of Mexican fans present and millions back home into raptures.
Germany must shrug off a rocky World Cup build-up as they begin the defence of their title on Sunday against a vastly experienced Mexico side jolted by their own pre-tournament scandal.
Despite the poor result, Low stressed that Die Mannschaft will not overhaul their tactics, though he admits that some flaws need to be ironed out.

"It goes without saying that the next match will be decisive for us, we have to win it", Loew added ahead of his team's next game against Sweden next Saturday. "We played without fear and my team-mates were incredible". "We have to focus on our strong points".
They have been battering teams in World Cup openers for as long as any of the players on this pitch could remember.
Like Germany, Mexico qualified easily for a seventh consecutive World Cup after punching their ticket to the finals with three matches to spare.
"We speak a lot about them and we consider them clearly superior", said Salcedo, who signed a four-year deal with Eintracht Frankfurt in May after spending the past season on loan with the Bundesliga club.
"We did not play our usual offensive and passing game", Loew said.
Mexico pulled back into a more defensive formation midway through the second half as key players exhausted and had to withstand heavy pressure from Germany.
"I think it's definitely the best goal I've ever scored in my life, we all dream of playing in the World Cup". By the final minutes, the tired Mexicans were playing more with their hearts than with their feet. "I don't really understand why we played like we played because, really, we already had our wake-up call".
Joshua Kimmich's acrobatic overhead kick looped onto the roof of the net, with substitute Edson Alvarez then blocking bravely to thwart Draxler.
Mexico are no World Cup novices, only Brazil and today's opponents have advanced from the group stages more often in the past nine tournaments. We want to get to the final.
