The announcement was made at the Frankfurt motor show by JLR chief executive Ralf Speth.
The jobs at the Solihull site would bring the total number of jobs it had created in the UK over the last three years to almost 11,000.
Most of the investment will go into designing systems to allow the chassis of future models to be made out of aluminium – the first of which are expected to be new mid-sized sports saloon cars that will be introduced in 2015.
Speaking to an expectant audience, Mr Speth said: "Today's announcement signals Jaguar Land Rover's ambitions to push the boundaries and redefine premium car ownership."
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."
Car manufacturers are keen on using aluminium in production as it is so much lighter than other materials available and increases fuel efficiency.
The first car using the aluminium platform will be a smaller than other Jaguar models, but it’s hoped that it will ultimately be flexible enough to be the base for future models of either Jaguar or Land Rover cars.
In order to demonstrate the flexibility of the system, JLR has also unveiled a concept car called the C-X17, which is halfway between a sports car and an SUV – breaking new ground for the car giant who is yet to venture into this area of the market. source: http://www.bbc.co.uk/news/business-24018350
