At the heart of the 2019 Bentley Bentayga is its engine. No matter which engine is equipped, the Bentayga is incredibly powerful. New for this year is a 4.0L V8 twin turbo making 542 hp, but the bigger 6.0L W12 engine, fed by two turbochargers, is still available and makes a full 600 hp. At the top of the line sits the Speed version of the Bentayga, utilizing the same W-12 engine, but with a little bit of extra tuning to bring the total horsepower number up to 626. All three engine choices are mated to an 8-speed automatic transmission, sending power to all four wheels. No matter which engine, the Bentayga should go from 0-60 in under 5 seconds. Picking out just the right way to equip one's new Bentayga is an adventure of its own. So many options and colors are available for the big SUV that it's easy to get lost within the features list. For example. the Bentayga's sound system includes 20 speakers and a 1950-watt amplifier, and not surprisingly, Bentley claims it's the most powerful stereo ever sold in an SUV. The Bentayga also includes a rear-seat entertainment system with two 10.2-inch screens set into the headrests that are removable and can be used as tablets. There's also a touchscreen remote located between the rear seats to control that infotainment system. Bentaygas are available in four distinct specifications, Touring, City, All-Terrain and Mulliner. All-Terrain Bentaygas come with a couple of unique driving modes that include a Mud and Trail mode and a Sand mode. Another nice little feature on the All-Terrain is a sump camera to assist in tricky off roading, a compass and altimeter also come standard on the All-Terrain. The City specification includes Park Assist functions and a top-view camera to make parking the large SUV easier. The City specification also can detect traffic signs and display speed limits and other road information in the dashboard. The City specification also has additional features to help avoid fender benders in urban areas. The Bentayga has an audible pedestrian warning system that will beep if someone steps into the vehicle's path, applying emergency braking if necessary. The Mulliner trim adds unique 22-inch wheels, Ombre Burr Walnut fade veneer interior, LED welcome lights, a console drink cooler and a Naim audio system. Additional options include ambient lighting, a rear entertainment system, front and rear-seat ventilation with massaging function, a two-tone premium leather-trimmed steering wheel, and rear foldable tables. The Touring specification adds adaptive cruise control and lane assist functions to the Bentayga. The adaptive cruise control can even be used in heavy traffic, allowing the Bentayga to come to a complete stop and then accelerate again as traffic allows. A night vision system can also warn drivers of potential hazards that might lurk beyond the view of the headlights.
