Unlike other websites and magazines, our ratings are not based solely on a singular road test, but rather a more encompassing batch of criteria: quality, safety, comfort, performance, fuel economy, reliability history and value. When comparing vehicles using our Rating System, it's important to note that the rating earned by each vehicle correlates only to the models within its class. For example, a compact car cannot be compared to a SUV—They are different vehicles altogether.
You can interpret our ratings in the following way:
5-Star: Outstanding vehicle. Only the most exceptional vehicles achieve this rating.
4-Star: Very Good vehicle. Very good and close to being the best vehicle in its class.
3-Star: Good vehicle. Decent, but not quite the best. Often affordable, but lacking key features found in vehicles of the same class.
2-Star: Below average vehicle. Not recommended, and lacking attributes a car buyer would come to expect for the price.
1-Star: Poor vehicle. Simply does not deserve to be on the road.
2016 Cadillac CT6 OVERVIEW
Cadillac’s brand-new, full-size prestige sedan seeks to rise right to the top of the automaker’s lineup. Because the CT6 will be offered in various markets, including China, it’s meant to signal Cadillac’s return to the global prestige luxury segment. New technologies are intended to make drivers aware of their surroundings, according to Cadillac. Aluminum-intensive construction incorporates 11 different materials.
What's New for 2016
Offered with a choice of three engines, the full-size CT6 luxury sedan is a brand-new model for 2016, strongly focused on technology. Auto Vehicle Hold prevents forward/rearward vehicle creep when the driver’s foot is off the brake pedal. A true 360-degree view around the vehicle, displayed in Cadillac’s CUE screen, helps reduce blind spots.
The industry-first surround-view video recording system can record front and rear views while driving, and an enhanced Night Vision helps identify people and large animals. A Rear Camera Mirror puts the rearward view into the inside mirror. Advanced Park Assist integrates automatic braking into automatic parking. Pedestrian Collision Mitigation technology also is new.
Choosing Your Cadillac CT6
Star of the powertrain trio is the new 3-liter Twin Turbo V6, generating 404 horsepower and 400 pound-feet of torque, for nearly 135 horsepower per liter. Cadillac says it’s the first application of cylinder deactivation technology to a turbo V6. Buyers can also choose a 2-liter turbo four-cylinder or a naturally aspirated 3.6-liter V6, producing 265 and 335 horsepower, respectively. Each engine mates with an eight-speed automatic transmission, but a different version is used for the Twin Turbo.
Active-on-demand all-wheel drive with a continuously variable clutch is standard with either V6 engine, whereas the four-cylinder model has rear-wheel drive. An available Active Chassis Package includes active rear steering, and Magnetic Ride Control. Any of three drive modes may be selected: Tour, Snow/Ice, and Sport.
Fuel economy with the Twin Turbo V6 is estimated at 18 mpg in city driving and 26 mpg on the highway, versus 19/28 mpg for the naturally aspirated V6 and 22/31 mpg for the four-cylinder.
Each of the three engines comes in a choice of two, three, or four trim levels:
Cadillac claims the CT6 is among the world’s lightest, most agile full-size luxury performance sedans, with interior space equivalent to BMW’s short-wheelbase 7 Series. Weight and agility are said to be closer to the BMW 5 Series and Mercedes-Benz E-Class. Prices range from $53,495 to $87,465. Tempting as the Twin Turbo might be, most buyers are likely to be satisfied with one of the less-potent engines. Careful study of standard-equipment lists is essential, since moving up a trim level can add either a few extra features or an overwhelming selection.
