We know the Cadillac CT5-V Blackwing is coming. The automaker has teased its upcoming debut and we've also seen a recent spy video. This won't be a typical Cadillac but rather a luxury muscle car. Among its many performance and track-focused lightweight features will include optional carbon fiber front seats and wheels made from forged magnesium alloy.

And now Cadillac Society claims it has learned those seats will have both heated and ventilated functions. Not every vehicle equipped with carbon fiber seats has that capability but since the CT5-V Blackwing will compete against segment heavyweights like the BMW M3 and M5 and Mercedes-AMG E63 S, luxury is still very much required.

The previously released teaser image showing those seats reveals that distinct carbon fiber weave complete with a laser-etched V logo. There are also racing harness cutouts that will come in handy for track day events. The steering wheel also boasts carbon fiber trim but its rim will be wrapped in leather. But it's what's happening under the sedan's hood that is most exciting.

GM's supercharged 6.2-liter LT4 V8 is back and rated at 640 horsepower and 630 lb-ft of torque. This is the same engine that powers the Chevy Camaro ZL1. Both a six-speed manual and a 10-speed automatic will be available.

Major suspension modifications are also on the agenda as are numerous exterior enhancements. We don't know yet when Cadillac plans a full reveal, but we've been told the CT5-V Blackwing will be a 2021 model. Pricing is also unknown but a fair assumption is a starting figure of around $85,000.

The CT5-V Blackwing will be joined by the smaller CT4-V Blackwing that's slated to come powered by the familiar 3.6-liter twin-turbo V6 with 464 hp and 445 lb-ft of twist on hand. However, the report states the CT4-V Blackwing will not offer the carbon fiber racing seats.
