CADILLAC CT4-V, CT5-V BLACKWING WILL SEE CARRYOVER ENGINES, BUT THERE’S MORE

The Upcoming Cadillac Performance Cars Give Us Powertrain Combos That ATS-V And CTS-V Never Did

CT5-V Blackwing

If you were hoping to see the 4.2L “Blackwing” V8 engine in upcoming high-performance Cadillac models, sorry. Sources familiar with what’s coming for the upcoming performance Cadillac portfolio have further confirmed to us once again that the DOHC “hot-V” 4.2L twin-turbo V8 engine found only in the CT6-V is indeed one and done. However, there’s plenty to get excited about.

MC&T has come to learn that both the range-topping CT4-V and CT5-V high performance sedans (which are expected carry on the “Blackwing” name) will each feature familiar engines. First is the 3.6L twin-turbo LF4 V6 for the CT4-V Blackwing, which is the ATS-V replacement. Then there’s the supercharged sledgehammer – the 6.2L LT4 V8 for the CT5-V, the CTS-V replacement. What’s more, both – yes both – vehicles will offer six-speed manual transmissions, as well as the fast-shifting 10-speed automatic.

This also means that these super Cadillacs will maintain a RWD layout, because it’s awesome.

Cadillac hasn’t offered a supercharged V8/stick shift combo since the discontinuation of the second-generation CTS-V, which also came in coupe and wagon body styles. To that end, we understand that the entirety of the Cadillac CT5 program to come in a single body style: a four-door sedan. That includes the CT5-V and CT5-V Blackwing. Like the gen-3 CTS-V, there will be no coupe, nor wagon.

Earlier this year, it was reported that GM would not be using the Blackwing V8 for any further products, in large part due to cost cutting measures. The CT5 sedan was originally intended to be produced on the Omega platform that underpins the CT6, however it has since been shuffled to the Alpha platform. This smaller platform does not meet the packaging requirements for the taller and wider DOHC Blackwing, thus rendering it a nonstarter. 

While we have no quarrels about the use of the LT4 supercharged V8 that was shared with the sixth-gen Camaro ZL1 and C7 Corvette Z06 in the upcoming high performance CT5-V Blackwing, the Blackwing V8 – otherwise known as the LTA – is an exciting piece of hardware that we would’ve loved to have seen proliferate through the Cadillac lineup. Under the hood of the CT6 sedan, the LTA V8 produces 500 horsepower and 553 pound-feet of torque, while the high-output variant delivers 550 horsepower and 627 pound-feet of torque.
