Charlie Sharples scored his first two Test tries as England prepared for the more ferocious challenges to come with a record 54-12 victory over Fiji.
The Gloucester wing, making his first Test start at Twickenham, was joined on the scoresheet by Ugo Monye, flanker Tom Johnson and centre Manu Tuilagi, who touched down twice late on against the tiring Fijians.
England's pack was so superior they struggled to retain control at times but their power did earn a penalty try while Fiji's captain and tight-head prop Deacon Manu was watching from the sin-bin.
The visitors did manage two second-half tries, from Metuisela Talebula and Seko Kelou.
England had talked about imposing themselves from the outset, about being ruthless and showing no mercy as they prepare to face Australia, South Africa and world champions New Zealand.
Head coach Stuart Lancaster will be satisfied with the seven-try performance, disappointed by the two tries they conceded and aware they will need to be more accurate when the Wallabies come to town next Saturday.
England must retain their fourth-place ranking through this most challenging autumn campaign to be among the top seeds when the 2015 World Cup draw is made on December 3.
Captain Chris Robshaw told Sky Sports 2 afterwards: "We were pretty slow coming out of the blocks today. We eventually warmed into the game but we cannot do that over the next three weeks."
Lancaster agreed with Robshaw and said England had "rusty areas" which need to be fixed before next week's clash against the Wallabies.
He added: "Next week and the week after and the week after that we are going to have to be more clinical."
