Fiat Chrysler has revealed that it will create 2,000 jobs in the United States, thanks to a $1 billion investment in its Michigan and Ohio factories by 2020.

The American-Italian firm's announcement came ahead of the major Detroit auto show, which kicked off Sunday and runs until January 22nd, and as car manufacturers feel the wrath of US President-elect Donald Trump on Twitter, predominantly for investing in Mexico.

Fiat Chrysler confirmed Michigan's Warren Truck Assembly Plant will be rolling out its Jeep and Grand Wagoneers, as well as the Ram heavy duty truck which it currently builds in Mexico.

The new Jeep pickup will be manufactured in Ohio's Toledo Assembly Complex.

The company said in a statement:

"FCA US is further demonstrating its commitment to strengthening its US manufacturing base."

Ford bowed to pressure from Trump last week, as it announced on Tuesday that it was shelving plans to construct a $1.6bn plant in Mexico and instead investing in the United States and creating 700 jobs in the process.

General Motors and Toyota raised Trump's online ire last week, with the latter being the first example of a non-US carmaker coming under fire.

Despite this precedent, German carmaker BMW has told the BBC that it is "absolutely" committed to its new $1bn plant in Mexico.

The head of Volkswagen has said that, while it will continue to produce cars in Mexico, its electric vehicles will be made in the US.

"Mr Trump I think wouldn't want us to produce cars and only export to Mexico. Mexico is for us a very big market as well...

"I think we are well positioned in America. We strongly invested in Chattanooga. We have one of the most modern plants here.

"We are really becoming an American car company now."
