Jeep teases plug-in hybrid Wrangler 4Xe

US off-road icon Jeep appears to be having an each-way bet on what will drive its future vehicles, teasing fans with images of a plug-in hybrid Wrangler barely a day after it showed off a gas-guzzling V8. A video of the upcoming Jeep Wrangler plug-in hybrid was posted on Instagram, and shows the vehicle gliding silently on an off-road track, without any sound of a combustion engine running.
