凯迪拉克近日证实，年初曝光的CT6-V将作为满血版V系列车型加入凯迪拉克高性能子品牌家族中。该车搭载的4.2升V8双涡轮增压引擎将被凯迪拉克正式命名为“黑翼”（Blackwing），虽然车厂并未解释这一名称的缘由，但至少听起来，“黑翼”是个很酷的名字。该引擎采用车厂全新设计，将极大的提升CT6的动力性。虽然CT6标准版轿车所搭载的3.0升V6双涡轮增压引擎功率已经达到301千瓦/404马力，但黑翼全铝引擎的功率提升至410千瓦/550马力，扭矩850牛米。该引擎采用车厂所谓的高性能V设计，排气歧管位于两组气缸之间的凹处而非从外面伸出。双涡管涡轮增压器也与排气歧管集成在一起位于引擎顶部，从而使这台双双顶置凸轮轴（DOHC）引擎设计更紧凑。按照车厂的说法，这可以有效降低涡轮迟滞现象。在引擎转速达到最高时，这些涡轮可以增加最多20磅的推力。车厂表示，CT6-V将于明年春季与消费者见面，而CTS-V和ATS-V也将作为2019款车型陆续推出。

 

Cadillac CT6-V Twin-Turbo 4.2-liter V8 Engine Named 'Blackwing'

Now that Cadillac has confirmed the CT6 V-Sport we saw earlier this year will officially join the performance sub-brand as a full-fledged V model, let’s take a moment and get to know it a bit better. That means spending some time looking at its 4.2-liter twin-turbo V8, which Cadillac is officially calling Blackwing for reasons we don't fully understand, aside from it being a pretty cool name.

 

The engine is a completely new design from the company, and it significantly bumps the CT6 up several notches in the performance category. Whereas the standard-issue sedan offers a maximum output of 404 horsepower (301 kilowatts) from a 3.0-liter twin-turbo V6, the Blackwing all-aluminum engine raises that bar to 550 hp (410 kW) and 627 pound-feet (850 Newton-meters) of torque.

 

It uses what the company calls a hot V design, with exhaust manifolds placed in the valley between the two cylinder banks instead of exiting on the outside. The twin-scroll turbochargers are also integrated into the manifolds at the top of the engine, creating a very compact DOHC powerplant that Cadillac also says has less turbo lag. At full speed, those turbos can add up to 20 pounds of boost.

 

Cadillac should have the CT6-V ready for buyers next spring, with the CTS-V and ATS-V available through the 2019 model years as they're phased out.
