  • Video: Potential C8 Motor

    Lots of info too. While we have discussed this before, here’s this question reframed, though presented in terms of potential CT5-V’s motor. But as we know, GM does family share many of its power plants.

    What Engine Will Power The Cadillac CT5-V?Cadillac looks poised to continue carving out its niche in the high-performance four-door luxury sedan segment with the upcoming CT5-V, which is slated to debut alongside the smaller CT4-V on May 30th. However, one big question remains: just what will power the Cadillac CT5-V?

    For those not up to speed on the newest Cadillac product, the CT5-V is the upcoming hot-to-trot version of the Cadillac CT5, which debuted just last month at the 2019 New York International Auto Show. The D-segment model will go head-to-head with heavy-hitting German rivals like the BMW M3 and Mercedes-AMG C63, and that means it’s gonna need some serious V8 firepower under the hood.

    And as far as we know at the moment, there are really only two options for what will be under the hood of the Cadillac CT5-V.
    2016 "LT4" 6.2L V-8 AFM VVT DI SC (LT4) for Cadillac CTS-V
    Supercharged 6.2L V8 LT4

    The first is GM’s supercharged 6.2L V8 Small Block LT4. In the outgoing, third-generation CTS-V, the LT4 made 640 horsepower at 6,400 rpm and 630 pound-feet of torque at 3,600 rpm. It was also found in such GM performance powerhouses like the Chevrolet Corvette C7 Z06 and sixth-gen Chevrolet Camaro ZL1. The LT4 is a very capable overhead valve (OHV, otherwise known as push-rod) performance mill, to say the least.

    Cadillac’s Twin-Turbo 4.2L V8 LTA “Blackwing”

    The other engine option to slot under the Cadillac CT5-V, is the twin-turbocharged 4.2L V8 LTA, otherwise known as Blackwing. Developed specifically for Cadillac, the unit is Cadillac’s first twin-turbo V8 engine and, unlike the push-rod LT4, the LTA utilizes a more sophisticated Dual-Overhead Cam (DOHC) design. Currently, the LTA is only available in the forthcoming Cadillac CT6-V, where it will produce 550 horsepower at 5,700 rpm and 627 pound-feet of torque at 3,200 rpm.
    Displacement 6.2L 4.2L
    Valve Configuration OHV DOHC
    Power (hp) 640 @ 6400 rpm (CTS-V) 550 @ 5700 rpm (2019 CT6-V)
    Torque (lb-ft) 630 @ 3600 rpm (CTS-V) 627 @ 3200 rpm (2019 CT6-V)
    Aspiration Supercharged Twin Turbocharged
    Charge Cooling Integrated dual coolant-to-air intercoolers Twin water-to-air intercoolers
    Fuel System Direct injection Direct injection
    Construction Type All-aluminum All-aluminum
    Fuel Type Premium required Premium required
    While both engines would provide the necessary output to make the forthcoming Cadillac CT5-V a beast, each engine also comes with its own unique character and personality. For example, the LT4 is more of an old-school, bombastic performance bombshell, whereas the LTA creates a more refined tidal wave of power.

    So, what do you think: will the Cadillac CT5-V use the supercharged 6.2L LT4 V8, the turbocharged 4.2L LTA V8 Blackwing, or some other engine entirely?

    What do you think we will see for the entry C8 or the Z06? Or will the 2020 Stingray motor be exclusively a LT2?

    John I have read some very intelligent theories from several of the mid engine forum experts over the development of the C8 stating that the base C8 will have the LT2 with improved horsepower and torque. The next level C8's I think (based on their comments) will have a chevy version of the LTA why else would they make these at BG. But the million dollar question that is anybody's guess is what will the top C8 have under the hood. I am guessing a supercharged/hybrid combo. Can't wait to find out the answers...

      I think ( HHHHOPE I’M INCORRECT ) that initially the C8 will only come with the upgraded LT1 ( The LT2 )

        I was reading about the GM powerplant factory near Niagara, and they are all geared up for some new engine(S)
        ....... Hoping that includes the 5.5L Twin Turbo too ( was hoping for the 6.2L Twin, But, Cie la Vie)
