For entry-level—but hardly base—versions of its Continental GT line, Bentley installs a V-8 in place of the usual W-12. Big B says excising four cylinders improves fuel economy, but we suspect its aim is mostly to sell more very expensive cars to more very wealthy people. La Bonnotte po-tay-toes, La Bonnotte po-tah-toes. Either way, the V-8 model is no ­penalty job—think IWC Schaffhausen case with an ETA Valgranges movement. Like the 12-cylinder, the Audi-derived eight-holer is strapped with two turbos, packs the output of a nuclear sub (500 horsepower and 487 pound-feet), and shoves you in the back like a schoolyard bully. “Distinctive V-8 growl” is listed as standard, but that sells it way, way short. With the top down in this GTC, the noise under full boot was so monstrous we checked our blind spots to see if someone had released a kraken.
