Found this info via Car and Driver and thought I should post it along with asking some questions.
Powertrain: Like the Discovery Sport and the Range Rover Evoque, the E-Pace will use a turbocharged inline-four, likely plucked from JLR’s new Ingenium engine family. A ZF-sourced nine-speed automatic transmission will be standard and help extract the most from whatever engine Jaguar chooses; all-wheel drive, naturally, will be included.
The Range Rover Evoques turbo four pot makes 240hp. That's not much of an issue but the turbo lag does seem to be one. Even from a rolling start of 5-60mph, it took the Evoque 9.3 seconds which is pretty long.
