British luxury carmaker Jaguar Land Rover has delayed the launch of its electric Range Rover and Jaguar models to allow time for more testing and for demand to pick up, The Guardian reported on Friday.

JLR is delaying the models to allow time for more testing and for EV demand to pick up, the Guardian newspaper reported.

Interest in electric luxury vehicles remains strong, but for some automakers, getting new models to market is proving slower than planned. More than 60,000 people have reportedly lined up for Range Rover’s first all-electric SUV. Jaguar, meanwhile, is staking its entire brand on an all-new, all-electric future.
