 Luxury car group Jaguar Land Rover JLR unveiled plans to go all-electric on Monday, saying it aims to be net zero on carbon emissions by 2039, as it joined a global race to roll out clean-energy vehicles. Land Rover will add six pure electric variants in the next five years and future Jaguar models would be built exclusively on a pure electric architecture, the British car giant said, adding that the first all-electric variant of Land Rover will debut in 2024.
