Jaguar Land Rover (JLR) is to create 1,700 jobs at its plant in Solihull as part of a £1.5 billion investment.
The money will go towards the introduction of new technically-advanced aluminium vehicle architecture in future models.
The first new model to showcase this will be a mid-sized sports saloon car from Jaguar to be launched in 2015.
Jaguar Land Rover chief executive Dr Ralf Speth announced the news at the Frankfurt Motor Show.
"Today's announcement signals Jaguar Land Rover's ambitions to push the boundaries and redefine premium car ownership," he said.
"At Jaguar Land Rover we place the customer at the heart of everything we do and the introduction of a world class all-new aluminium vehicle architecture means we will be more competitive, flexible and efficient delivering exciting new products for our customers around the world.
"Jaguar Land Rover is a business driven by design, technology and innovation and this investment and level of job creation is yet further evidence of our commitment to advancing the capability of the UK automotive sector and its supply chain."
The 1,700 new jobs at the Solihull site in the West Midlands will bring the total number of UK manufacturing jobs announced by Jaguar Land Rover over the last three years to almost 11,000.
Business Secretary Vince Cable said: "Jaguar Land Rover has been experiencing great success over the last couple of years but this ground-breaking project takes Jaguar on to the next level.
"This all-aluminium architecture project typifies the type of innovative and high value R&D that the UK excels in and government is supporting through the automotive industrial strategy."
