The new higher range is available on the single-motor Extended Range car, priced from £45,875 and fitted with a 77kWh battery. 0-62mph time at 6.4sec.
The twin-motor four-wheel-drive Explorer, uses a slightly larger 79kWh battery but has a reduced range of 329 miles. 0-62mph time at 5.3sec - quicker, it highlights, than a Ford Focus ST.
The range-topper can also tow loads of up to 1200kg.
A lower-powered Standard Range car, with a 168bhp rear motor, a smaller 52kWh battery and a maximum charging speed of 125kW, will be added to the line-up in due course, taking the price down to £39,875.
As for options and trims - only two options are available: a panoramic glass roof and a driver assist pack which brings a hands-free bootlid, a head-up display, 360deg parking camera and lane-change assist.
There are also just two trims on offer for the Explorer: Select and Premium. All cars come with a heated steering wheel, heated seats (with massage function for the driver), wireless smartphone charging and wireless smartphone mirroring.
Premium trim adds a 10-speaker Bang & Olufsen sound system, ambient lighting and dynamic matrix LED headlights with 'glare-free' high beam function.
