Right now you can buy a brand new Bentley Bentayga with that ridiculous twin-turbocharged 6.0-liter W12 with 600 hp and 663 lb-ft of torque. A 4.0-liter diesel V8 can also be had, but it's the W12 that people talk about. Fortunately, AutoGuide has confirmed, thanks to a leaked National Highway Transportation and Safety VIN decoder document for the '19 Bentayga, that the upcoming twin-turbo 4.0-liter V8 option will have 542 hp – exactly the same output found in the new Porsche Cayenne Turbo, which shares that engine. Until now, this was a rumor.

The other piece of Bentayga news involves the also upcoming plug-in hybrid variant. Automotive News has confirmed it'll debut this March at Geneva. This time, however, it'll share its powertrain with the Porsche Panamera 4 E-Hybrid. That means the 2.9-liter twin-turbo V6 is paired to an electric motor with power being sent to all four wheels through an eight-speed automatic. All told, expect this powertrain to deliver around 462 hp. The Panamera can do 30 miles of all-electric range, so expect a similar figure for the Bentayga. Based on everything, it'd make sense for Bentley to debut the twin-turbo V8 alongside the plug-in hybrid at the Swiss show. That way, sales will get underway sometime next summer or early fall.

And yes, both new engine options will be available in the US. As for the W12? It's not going anywhere. It'll still remain the king of the Bentayga engine range, as it rightly should.I will also, more than likely, be the most expensive, followed by the plug-in.
