SANTA CLARA, Calif. -- Racing out to six straight wins to open the season against a less than formidable schedule left some people doubting how good the San Francisco 49ers actually are. Blowing out a Carolina team that had won four straight games should quiet some of those critics.
Tevin Coleman scored three of his four touchdowns in the first half, rookie Nick Bosa had three sacks to go along with an acrobatic interception and the 49ers remained unbeaten with a 51-13 victory over the Carolina Panthers on Sunday in their highest-scoring game in 26 years.
"It doesn't really matter what the outside world thinks," said cornerback Richard Sherman, who had an interception. "We know what we have in this building. The same thing we've said since training camp, we'll continue to say. We knew the talent we have, we just have to execute and focus on us and let the chips fall where they may."
The Niners (7-0) are off to their best start since winning their first 10 games in 1990 and now have a second win against a team with a winning record thanks to a complete performance against the Panthers (4-3).
Jimmy Garoppolo and the offense had little trouble carving Carolina's defense with 232 yards rushing and a pair of touchdown passes for San Francisco's most prolific offensive game since beating Detroit 55-17 on Dec. 19, 1993. The Niners stellar defense did the rest.
San Francisco intercepted three passes from Kyle Allen, who came into the game with no interceptions on 153 career attempts while winning his first five starts in place of injured starter Cam Newton. They also had seven sacks, with Bosa getting three of them to go along with his leaping interception and 46-yard return on the final play of the third quarter.
"Whenever your moves are working really good, it's a good feeling," Bosa said. "Once you get a sack early you calm down."
Coleman did most of the rest of the damage. He scored on a 19-yard run in the first quarter, added a 10-yard catch in the second quarter, broke the game open with a 48-yard run late in the first half and added a 1-yard run late in the third quarter.
Coleman finished with 11 carries for 105 yards and two catches for 13 yards. He became just the fourth 49ers player to score at least four touchdowns in a regular-season game, joining Jerry Rice (1993, 1990) and Billy Kilmer (1961). Rice holds the team record with five TDs against Atlanta in 1990.
"He knows how to play in the offense," coach Kyle Shanahan said. "He had some good looks today, and when Tevin has a good look, he usually can get in the end zone."
Garoppolo finished 18 for 22 for 175 yards with TD passes to Coleman and Emmanuel Sanders.
Allen went 19 for 37 for 158 yards on a day that Newton was able to take warmups before the game in a sign that he could be close to being ready to return from a foot injury that has sidelined him since Week 2.
Christian McCaffrey was the lone bright spot on Carolina's offense with 117 yards rushing and a TD and 38 yards receiving.
"They showed up. We didn't," Panthers defensive lineman Gerald McCoy said. "We just didn't come here today and be who we were supposed to be and play like we were supposed to play. We have to do a better job of not beating ourselves. We did a lot of wrong out there today."
The 49ers made a trade earlier in the week to acquire Sanders from Denver and it paid off almost immediately. Sanders caught two passes on the opening drive, including a 4-yard TD from Garoppolo . He finished with four catches for 25 yards.
"It was probably one of the easiest touchdowns I have had," Sanders said. "It was awesome to get on the opening drive to be a newcomer on this team and be able to open up like that is awesome."
Niners kickoff specialist Mitch Wishnowsky got called for a rare personal foul when he was called for lowering his helmet to initiate contact on Carolina returner Reggie Bonnafon in the second quarter. That gave the Panthers the ball at the 49ers 47 to start the drive but a holding penalty on Trai Turner wiped out a long run by McCaffrey and a sack by D.J. Jones led to a stalled drive for Carolina.
Panthers: WR Jarius Wright left with a leg injury in the second half.
49ers: RB Matt Breida left after injuring his ankle late in the first half. ... RB Jeff Wilson left in the fourth quarter with a stinger.
Panthers: Host Tennessee on Sunday.
49ers: Visit Arizona on Thursday night.
