Trump said his message was the need to start 'a conversation about how to make America great again for everyone, especially – and I say especially – for those who have the very least.'
But most of his largest applause lines were slaps at Clinton, including some that linked Democratic politicians to Detroit's crumbling, crime-ridden inner city.
'The city of Detroit is the living, breathing example of my opponent's failed economic agenda,' Trump said. 'Every policy that has failed this city, and so many others, is a policy supported by Hillary Clinton.'
'She supports the high taxes and radical regulation that forced jobs out of your community, and the crime policies have made you far, far less safe, and the immigration policies that have strained local budgets, and the trade deals like NAFTA, signed by her husband, that have shipped your jobs to Mexico and other countries.'
'And she supports the education policies that deny your students choice, freedom and opportunity,' he continued, to wild applause.
'She is the candidate of the past. Ours is the campaign of the future.'
'OUT OF IDEAS': Trump clobbered his opponent, saying that 'if you were a foreign power looking to weaken America, you couldn't do better than Hillary Clinton's economic agenda'
'This is a city controlled by Democratic politicians at every level. And unless we change policies, we will not change results,' Trump said 'One hundred per cent.'
'Our opposition ... has long ago run out of ideas,' Trump said, promising an expansion of his economic proposals on his website.
'All Hillary Clinton has to offer is more of the same. More taxes, more regulations, more bureaucrats, more restrictions on American energy and on American production. More of that!'
'If you were a foreign power looking to weaken America, you couldn't do better than Hillary Clinton's economic agenda. Nothing would make our foreign adversaries happier than for our country to tax and regulate our companies and our jobs right out of existence.'
After Trump left the podium, a female emcee said: 'I want to apologize to all of you and to Mr. Trump for the interruptions. This is not what the Detroit Economic Club is all about.'
Indiana Gov. Mike Pence, Trump's running mate, introduced the billionaire candidate.
'We've become best friends. He seems like somebody I've known all my life,' said Pence.
'He's a dreamer. He's a builder. He's a driver. And he's a man who speaks his mind.'
