The economy is steaming along and we have seen the positive effect in the global performance car sales. For Cadillac a reason to launch a new high-performance sedan, the CT6 V-Sport. And this is the brand’s first-ever twin-turbo V-8 engine and aims to compete with cars like the BMW M5. Great news for those that live in North America, but Cadillac is not launching this model in the European markets, at least for now!
The new Cadillac Twin Turbo V-8 is a clean-sheet design that also introduces unique design elements developed to balance performance and efficiency with compact, mass-efficient packaging. At the center of the 4.2L Twin Turbo V-8 is a “hot V” configuration that transposes the conventional layout of the cylinder heads’ intake and exhaust systems to mount the turbochargers at the top of the engine — in the valley between the heads — to virtually eliminate turbo lag and reduce the engine’s overall packaging size.
In a conventional turbocharged engine, the cylinder heads receive the pressurized air charge through ports at the top of the engine and the exhaust exits through ports on the lower outside of the heads into manifolds connected to the turbochargers. With Cadillac’s innovative hot V design, the intake-charged air enters through the lower outside of the heads and exits through the top inside — where the turbochargers are integrated with the exhaust manifolds — for quick spool-up that translates into more immediate power delivery. The design also allows closer mounting of the catalytic converters, for efficient packaging.
