Tata Motors has plans of sharing engines with Jaguar/Land Rover products according to a report on BS Motoring.com.  Most of the engines that are presently used on Jaguar and Land Rover owe their lineage to Ford from whom Tata purchased J-LR.  Tata also relies on Fiat for engines for some of its cars.  The Tata Group has now decided to embark on a plan of engine development that could see the new engines utilised by Tata, Jaguar and Land Rover.
