For starters, while we know that the mainstream 2017 XE will ultimately offer three engines, a manual transmission, and rear- or all-wheel drive, so far Jaguar’s only talking about two of the engines, one ZF eight-speed automatic, and the rear- and all-wheel drive bits. As we were already aware, the XE’s top-flight engine will be a supercharged 3.0-liter V-6 making 340 horsepower and 332 lb-ft of torque—a version we’ve already driven. Jag has dubbed that XE variant “XE 35t.” The other engine Jag is talking about at this time is a 2.0-liter turbo-diesel four-cylinder making 180 horsepower and 318 lb-ft of torque, and models so equipped will be badged “XE 20d.” Pulled from the new Ingenium engine family, the diesel is expected to be very efficient (no EPA figures are available yet), and thanks to largely aluminum construction it will be relatively light-weight at just 304 pounds. Both engines are mated to a ZF eight-speed automatic, and both can be paired with rear- or all-wheel drive.
