Spotted: 2018 Bentley Continental GTC Convertible Share Comments Previous ImageNext ImagePreviousNextView Large The Bentley Continental GTC was spotted testing earlier this year, and now our spy photographers have caught the convertible version of the GTC testing in Germany. As usual, the body is covered in camo, but we know that this all new Continental GT/GTC will be based on the MSB platform, which it will share with the Porsche Panamera. The advantage being that, not only will it share the same underpinnings as the, apparently, excellent Porsche, but the Bentley will also be able to make use of the hybrid drivetrain. The move also saves development time and money. The car is expected to have a 600 hp W12 at the top of the range, and 4.0L V8 lower down in the range.
