This latest Ingenium engine is a turbocharged 2.0-liter gasoline four-cylinder like the older Jag engine it replaces; this one has its exhaust manifold integrated into the cylinder head, and it uses a twin-scroll turbocharger. It produces 247 horsepower and 269 pound-feet of torque, which are improvements of 7 hp and 18 lb-ft over the XE's old turbocharged four. Plus, peak torque is also available a bit lower than with the previous engine, at 1,200 rpm versus 1,750. It shares its architecture with the Ingenium diesel four-cylinder.
The XE also gets some powertrain love at the top of the range, borrowing an engine from its bigger siblings. Jaguar is introducing a new XE S model with the 380-horsepower supercharged 3.0-liter V6. Previously, the most powerful engine available on the XE was the 340-horsepower version of that V6, which will still be available. The XE gets another upgrade in the form of an available 12.3-inch instrument panel display, when optioned with the Jaguar Touch Pro infotainment system that's also available on the other models.
The big news for the XF is that its base price drops ever so slightly now that a four-cylinder model has been added. The rear-drive model with the new Ingenium engine starts at $48,770 as opposed to $49,245 for the cheapest 2017 XF, which had a diesel four-cylinder and rear-wheel drive. The downside is that diesel buyers will be paying $50,270 for the 2018 version of the same car.
Some other technology upgrades have permeated the lineup as well. These 2018 Jaguars will be available with a forward cross-traffic alert and a system that will show steering angle and distance to objects on screen during slow forward maneuvering. The latter seems mainly useful for tight parking spaces. These features are available with Jaguar's Surround Camera System. Jaguar also introduced a system that will allow users to pay for gas (or diesel) from the car's touch screen using Apple Pay, Android Pay, or PayPal. The system will be introduced first in the UK and later this year in other markets, and it can only be used at Shell gas stations.
