2016 Cadillac CT6 avant-garde styling and high-tech features are great, but the CT6 sheds the Cadillac clichés in an attempt to best its European rivals. A 265-hp 2.0-liter turbo four and eight-speed automatic drive the rear wheels; the optional 335-hp 3.6-liter V-6 and 404-hp 3.0-liter twin-turbo V-6 get all-wheel drive. Onboard Wi-Fi with 4G LTE is standard, and a large touchscreen offers Apple CarPlay and Android Auto. High-end options include a 34-speaker stereo, giant sunroof and adaptive cruise control.
