Bentley is offering up a new kind of Continental GT Coup? with a "smaller" engine. The 4-liter V8 with a double twin-scroll turbocharger is the little brother to the 6-liter, 12-cylinder model. The V8 features 373 horsepower, which is 50 less than the W12 - but Bentley says the car's new engine uses 40 percent less petrol.
